The very first article on chiropractic listed in ‘Medline’ was published 100 years ago in the ‘California State Journal of Medicine’ without the author’s name. It is a beauty! Here I take the liberty of re-publishing it in full.
Some people are really so terribly modest that it is a mystery how they can live, or even be willing to live, in a world so filled with pushing braggarts and rampant commercialism. For example, note the list of things that E. R. Blanchard D.C., (graduate chiropractor), intimates that he can cure:
“Adhesions, anemia, asthma, appendicitis, blood poison, bronchitis, backache, biliousness, catarrh, constipation, chills and fever, diabetes, dropsy, dizziness, drug and alcohol habits, diarrhoea, deafness, eczema, eye diseases, female diseases, gallstones, gravel, goitre, hay fever, indigestion, lumbago, locomotor ataxia, malaria, nervousness, neuralgia, paralysis, piles, pneumonia, rickets, ruptures, rheumatism, St. Vitus’ dance, suppressed or painful menstruation, scrofula, tumors, worms, bed wetting and other child’s diseases, leucorrhoea, or whites, stricture, emissions, impotence and many other diseases.”
This is almost as long a list as that compiled by the wealthy and admired Law brothers in connection with what they say they can cure with the wonderful Viavi, that prize of all fakes!
One hundred years later, it seems to me, not a lot has changed:
A review of 200 chiropractor websites and 9 chiropractic associations’ claims in Australia, Canada, New Zealand, the United Kingdom, and the United States was conducted between. The outcome measure was claims (either direct or indirect) regarding eight reviewed conditions, made in the context of chiropractic treatment. The results demonstrated that 190 (95%) chiropractor websites made unsubstantiated claims.
This article was posted a few months ago. Then it mysteriously vanished without a trace; nobody knows quite why or how. Today I found an old draft on my computer, so I post the article again. It might not be identical with the original but it is close enough, I think.
Some time ago, Andy Lewis formulated a notion which he called ‘Ernst’s law’. Initially, I felt this was a bit o.t.t., then it made me chuckle, and eventually it got me thinking: could there be some truth in it, and if so, why?
The ‘law’ stipulates that, if a scientist investigating alternative medicine is much liked by the majority of enthusiasts in this field, the scientist is not doing his/her job properly. In any other area of healthcare, such a ‘law’ would be absurd. Why then does it seem to make sense, at least to some degree, in alternative medicine? The differences between any area of conventional and alternative medicine are diverse and profound.
Take neurology, for instance: here we have an organ-system, anatomy, physiology, pathophysiology, etiology and nosology all related more or less specifically to this field and all based on facts, rigorous science and substantial evidence. None of this knowledge, science and evidence is static, but each has evolved and can be predicted to do so in future. What we knew about neurology 50 years ago, for example, was dramatically different from what we know today. Scientific discovery discoveries in neurology link up with the knowledge gathered in other areas of medicine to generate a (more or less) complete bigger picture.
In alternative medicine or any single branch thereof, we have no specific organ-system, anatomy, physiology, pathophysiology, etiology or nosology to speak of. We also have few notions that are transferable from one branch of alternative medicine to another – on the contrary, the assumptions of homeopathy, for example, are in overt contradiction to those of acupuncture which, in turn, are out of sync with those of reflexology, aromatherapy and Reiki.
Instead, each branch of alternative medicine has its own axioms that are largely detached from reality or, indeed, from the axioms of other branches of alternative medicine. In acupuncture, for instance, we have concepts such as yin and yang, qi, meridians and acupuncture points, and there is hardly any development of these concepts. This renders them akin to dogmas, and there is no chance in hell that the combination of all the branches of alternative medicine would add up to provide a sensible ‘bigger picture’.
If a scientist were to instill scientific, critical, progressive thought in a field like neurology, thus overthrowing current concepts and assumptions, they would be greeted with open arms among many like-minded researchers who all pursue the aim of advancing their field and contributing to the knowledge base by overturning wrong assumptions and discovering new truths. If researchers were to spend their time trying to analyse the concepts or treatments of alternative medicine, thus overthrowing current concepts and assumptions, they would not only not be appreciated by the majority of the experts working in this field, they would be castigated for their actions.
If a scientist dedicated decades of hard work to the rigorous assessment of alternative medicine, that person would become a thorn in the flesh of believers. Instead of welcoming him with open arms, some disappointed enthusiasts of alternative treatments might even pay for defaming them.
On the other hand, if a researcher merely misused the tools of science to confirm the implausible assumptions of alternative medicine, he would quickly become the celebrated ‘heroes’ of this field.
This is the bizarre phenomenon that ‘Ernst’s law’ seems to capture quite well – and this is why I believe the ‘law’ is worth more than a laugh and a chuckle. In fact, ‘Ernst’s law’ might even describe the depressing reality of retrograde thinking in alternative medicine more accurately than most of us care to admit.
What do my readers feel? Their comments following this blog may well confirm or refute my theory.
Several sceptics including myself have previously commented on this GP’s bizarre promotion of bogus therapies, his use of disproven treatments, and his advocacy for quackery. An interview with Dr Michael Dixon, OBE, chair of the ‘College of Medicine’, and advisor to Prince Charles, and chair of NHS Alliance, and president of the ‘NHS Clinical Commissioners’ and, and, and…was published on 15 November. It is such a classic example of indulgence in fallacies, falsehoods and deceptions that I cannot resist adding a few words.
To make it very clear what is what: the interviewer’s questions are in bold Roman; MD’s answers are in simple Roman; and my comments are in bold italic typeface. The interview itself is reproduced without changes or cuts.
How did you take to alternative medicine?
I started trying out alternative medicine after 10 years of practising as a general physician. During this period, I found that conventional medicine was not helping too many patients. There were some (patients) with prolonged headaches, backaches and frequent infections whom I had to turn away without offering a solution. That burnt me out. I started looking for alternative solutions.
The idea of using alternative treatments because conventional ones have their limits is perhaps understandable. But which alternative therapies are effective for the conditions mentioned? Dr Dixon’s surgery offers many alternative therapies which are highly unlikely to be effective beyond placebo, e.g. ‘Thought Field Therapy’, reflexology, spiritual healing or homeopathy.
But alternative medicine has come under sharp criticism. It was even argued that it has a placebo effect?
I don’t mind what people call it as long as it is making patients better. If the help is more psychological than physiological, as they argue, all the better. There are less side-effects, less expenses and help is in your own hands.
I have posted several articles on this blog about this fundamental misunderstanding. The desire to help patients via placebo-effects is no good reason to employ bogus treatments; effective therapies also convey a placebo-response, if administered with compassion. Merely administering placebos means denying patients the specific effects of real medicine and is therefore not ethical.
Why are people unconvinced about alternative medicine?
One, there are vested interests – professional and organizational impact on it. Two, even practitioners in conventional medicine do not know much about it. And most importantly, we need to develop a scientific database for it. In conventional medicine, pharmaceutical companies have the advantage of having funds for research. Alternative medicine lacks that. Have people who say alternative medicine is rubbish ever done research on it to figure out whether it is rubbish? The best way to convince them is through the age-old saying: Seeing is believing.
1) Here we have the old fallacy which assumes that ‘the establishment’ (or ‘BIG PHARMA’ ) does not want anyone to know how effective alternative treatments are. In truth, everyone would be delighted to have more effective therapies in the tool-kit and nobody does care at all where they originate from.
2) GPs do not know much about alternative medicine, true. But that does not really explain why they are ‘unconvinced’. The evidence shows that they need more convincing evidence to be convinced.
3) Dixon himself has done almost no research into alternative medicine (I know that because the few papers he did publish were in cooperation with my team). Contrary to what Dixon says, there are mountains of evidence (for instance ~ 20 000 articles on acupuncture and ~5000 on homeopathy in Medline alone); and the most reliable of this evidence usually shows that the alternative therapy in question does not work.
4) Apologists lament the lack of research funds ad nauseam. However, there is plenty of money in alternative medicine; currently it is estimated to be a $ 100 billion per year business worldwide. If they are unable to channel even the tiniest of proportions into a productive research budget, only they are to blame.
5) Have people who say alternative medicine is rubbish ever done research on it to figure out whether it is rubbish? Yes, there is probably nobody on this planet who has done more research on alternative medicine than I have (and DM knows it very well, for about 15 years, he tried everything to be associated with my team). The question I ask myself is: have apologists like Dixon ever done rigorous research or do they even know about the research that is out there?
6) Seeing is believing??? No, no, no! I have written several posts on this fallacy. Experience is no substitute for evidence in clinical medicine.
Will alternative medicine be taught in UK universities?
US already has 16 universities teaching it. The College of Medicine, UK, is fighting hard for it. We are historically drenched in conventional medicine and to think out of the box will take time. But we are at it and hope to have it soon.
1) Yes, the US has plenty of ‘quackademia‘ – and many experts are worried about the appalling lack of academic standards in this area.
2) The College of Medicine, UK, is fighting hard for getting alternative medicine into the medical curriculum. Interesting! Now we finally know what this lobby group really stands for.
3) Of course, we are ‘drenched’ in medicine at medical school. What else should we expose students to?
4) Thinking ‘out of the box’ can be productive and it is something medicine is often very good at. This is how it has evolved during the last 150 years in a breath-taking speed. Alternative medicine, by contrast, has remained stagnant; it is largely a dogma.
What more should India do to promote integrated medicine?
India needs to be prouder of its institutions and more critical of the West. The West has made massive mistakes. It has done very little about long-term diseases and in preventing them. India needs to be more cautious as it will lead the world in some diseases like the diabetes. It should not depend on conventional medicine for everything, but take the best for the worst.
To advise that India should not look towards the ‘West’ for treating diabetes and perhaps use more of their Ayurvedic medicines or homeopathic remedies (both very popular alternatives in India) is a cynical prescription for prematurely ending the lives of millions prematurely.
Today, Prince Charles celebrates his 65th birthday. He is one of the world’s most tenacious, outspoken and influential proponent of alternative medicine and attacker of science – sufficient reason, I think, to join the birthday-celebrations by outlining a chronology of his love affair with quackery. The following post highlights just a few events (there are so many more!) which I happen to find interesting. As I was personally involved in several of them, I have tried to stay as close as possible to the text published by journalists at the time (with links to the originals); this, I thought, was fairer than providing my own, possibly biased interpretations.
The origins Charles’ passion for all things alternative are not difficult to trace. The Royal family is famous for using homeopathy and other doubtful treatments while they are healthy, and for employing the very best conventional medicine has to offer as soon as they are ill. This pattern also applied to Charles’ childhood, and it is more than likely that this is how his weakness for alternative medicine and charlatans first started.
The young Prince Charles went on a journey of ‘spiritual discovery’ into the wilderness of northern Kenya. His guru and guide was Laurens van der Post (who was later discovered to be a fraud and compulsive fantasist and to have fathered a child with a 14-year old girl entrusted to him during a sea voyage). Van der Post wanted to awake Charles’ young intuitive mind and attune it to the ideas of Carl Jung’s ‘collective unconscious’ which allegedly unites us all through a common vital force. It is this belief in vitalism (long obsolete in medicine and science) that provides the crucial link to alternative medicine: virtually every form of the otherwise highly diverse range of alternative therapies is based on the assumption that some sort of vital force or energy exists. Charles was so taken by van der Post that, after his death, he established an annual lecture in his honour.
Throughout the 1980s, Charles seems to have lobbied for the statutory regulation of chiropractors and osteopaths in the UK. In 1993, it finally became reality.
Osteopathy has strong Royal links: Prince Charles is the President of the GOsC; Princess Diana was the President of the GCRO; and Princess Anne is the patron of the British School of Osteopathy (statement dated 2011).
In 1982, Prince Charles was elected as President of the British Medical Association (BMA) and promptly challenged the medical orthodoxy by advocating alternative medicine. In a speech at his inaugural dinner as President, the Prince lectured the medics: ‘Through the centuries healing has been practised by folk healers who are guided by traditional wisdom which sees illness as a disorder of the whole person, involving not only the patient’s body, but his mind, his self-image, his dependence on the physical and social environment, as well as his relation to the cosmos.’ The BMA-officials were impressed – so much so that they ordered a full report on alternative medicine which promptly condemned this area as utter nonsense.
In 1993, Charles founded his often re-named lobby group that ended up being called the ‘Foundation for Integrated Health’ (FIH). It was closed down in 2010 amidst allegations of money laundering and fraud. Its chief executive, George Gray, was later convicted and went to jail. The FIH had repeatedly been economical with the truth. For instance, when it published a DoH-sponsored ‘patient guide’ that was entirely devoid of evidence, arguably the most important feature of such a document. They claimed evidence was never meant to be included. But I had seen a draft where it had been part of it, and friends have seen the contract with the DoH where “evidence” was an important element.
In 2000, Charles wrote an open letter to The Times (citing my work twice!!!) stating that…It makes good sense to evaluate complementary and alternative therapies. For one thing, since an estimated £1.6 billion is spent each year on them, then we want value for our money. The very popularity of the non-conventional approaches suggests that people are either dissatisfied with their orthodox treatment, or they find genuine relief in such therapies. Whatever the case, if they are proved to work, they should be made more widely available on the NHS…But there remains the cry from the medical establishment of “where’s the proof?” — and clinical trials of the calibre that science demands cost money…The truth is that funding in the UK for research into complementary medicine is pitiful…So where can funding come from?…Figures from the department of complementary medicine at the University of Exeter show that less than 8p out of every £100 of NHS funds for medical research was spent on complementary medicine. In 1998-99 the Medical Research Council spent no money on it at all, and in 1999 only 0.05 per cent of the total research budget of UK medical charities went to this area…
In 2001, Charles was working on plans to help build a model hospital that would tap into the power of alternative therapy. It was to train doctors to combine conventional medicine and alternative treatments, such as homeopathy, Ayurvedic medicine and acupuncture, and was to have have up to 100 beds. The prince’s intervention marked the culmination of years of campaigning by him for the NHS to assign a greater role to alternative medicine. In a speech he had urged the NHS not to dismiss it as a “woolly cul-de-sac”. Groups interested in alternative medicine were delighted at the news. Teresa Hale, founder of the Hale Clinic in London, said: “Twenty-five years ago people said we were quacks. Now several branches, including homeopathy, acupuncture and osteopathy, have gained official recognition.” The proposed hospital, which was due to open in London in 2003 or early 2004, was to be overseen by Mosaraf Ali, who runs the Integrated Medical Centre (IMC) in London. He was also responsible for raising finance for its construction.
To the best of my knowledge, this hospital never materialised. This might be due to Mosaraf Ali falling in disrepute: Raj Bathija, 69 and from India, went for a massage at the clinic of Dr Mosaraf Ali and his brother Imran in 2005 after suffering from two strokes. However, he claims that shortly after the treatment, his legs became pale and discoloured. Four days afterwards, Mr Bathija was admitted to hospital, where he had to have both legs amputated below the knee due to a shortage of blood. According to Mr Bathija, Dr Ali and his brother were negligent in that they failed to diagnose his condition and neglected to advise him to go to hospital.
His daughter Shibani said: “My father was in a wheelchair but was making progress with his walking. He hoped he might become a bit more independent. With the amputations, that’s all gone.”
In 2003, Prince Charles’ Prince of Wales’ FIH has launched a five-year plan which outlined how to improve access to therapies.
In 2004, Charles publicly supported the Gerson diet as a treatment for cancer and Prof Baum, one of the UK’s most eminent oncologists, was invited to respond in an open letter to the British Medical Journal: …Over the past 20 years I have treated thousands of patients with cancer and lost some dear friends and relatives to this dreaded disease…The power of my authority comes with knowledge built on 40 years of study and 25 years of active involvement in cancer research. Your power and authority rest on an accident of birth. I don’t begrudge you that authority but I do beg you to exercise your power with extreme caution when advising patients with life-threatening diseases to embrace unproven therapies.
In 2005, the ‘Smallwood-Report’ was published, commissioned by Charles and paid for by Dame Shirley Porter, specifically to inform health ministers. It stated that up to 480 million pounds could be saved if one in 10 family doctors offered homeopathy as an alternative to standard drugs. Savings of up to 3.5 billion pounds could be achieved by offering spinal manipulation rather than drugs to people with back pain. Because I had commented on this report, Prince Charles’ first private secretary asked my vice chancellor to investigate my activities; even though I was found to be not guilty of any wrong-doing, specifically of violating confidentiality, all local support stopped which led to my early retirement. ITV later used this incident in a film entitled THE MEDDLING PRINCE.
In a 2006 speech Prince Charles told the World Health Organisation in Geneva that alternative medicine should have a more prominent place in health care. The Prince urged every country to come up with a plan to integrate conventional and alternative medicine into the mainstream. But British science struck back. Anticipating Prince Charles’s sermon in Geneva, thirteen of Britain’s most eminent physicians and scientists issued a widely quoted “Open Letter: Use of ‘Alternative’ Medicine in the NHS”. The letter expressed concern over “ways in which unproven or disproved treatments are being encouraged for general use in Britain’s National Health Service.” The signatories, who included three Fellows of the Royal Society, one Nobel Laureate (Sir James Black, FRS) and the son of another (Professor Gustav Born, FRS), cited the overt promotion of homeopathy by the NHS, including its official website. The Open Letter warned that “it would be highly irresponsible to embrace any medicine as though it were a matter of principle.”
In 2008, The Times published my letter asking the FIH to recall two guides promoting “alternative medicine”, saying: “the majority of alternative therapies appear to be clinically ineffective, and many are downright dangerous.” A speaker for the FIH countered the criticism by stating: “We entirely reject the accusation that our online publication Complementary Healthcare: A Guide contains any misleading or inaccurate claims about the benefits of complementary therapies. On the contrary, it treats people as adults and takes a responsible approach by encouraging people to look at reliable sources of information… so that they can make informed decisions. The foundation does not promote complementary therapies.”
In 2009, the Prince held talks with the health Secretary to persuade him to introduce safeguards amid a crackdown by the EU that could prevent anyone who is not a registered health practitioner from selling remedies. This, it seems, was yet another example of Charles’ disregard of his constitutional role. In the same year, Charles urged government to protect alternative medicine medicine because “we fear that we will see a black market in herbal products”, as Dr Michael Dixon, medical director of Charles’ FIH, put it.
In 2009, Charles seemed to have promised that his London-based ‘College of Integrated Medicine’ (the name was only later changed to ‘College of Medicine’, see below) was to have a second base in India. An Indian spokesman commented: “The second campus of the Royal College will be in Bangalore. We have already proposed the setting up of an All India Institute of Integrated Medicine to the Union health ministry. At a meeting in London last week with Prince Charles, we finalized the project which will kick off in July 2010”.
In 2010, Charles publicly stated that he was proud to be perceived as ‘an enemy of the enlightenment’.
In 2010, ‘Republic’ filed an official complaint about FIH alleging that its trustees allowed the foundation’s staff to pursue a public “vendetta” against a prominent critic of the prince’s support for complementary medicines, Edzard Ernst. It also suggests the imminent closure of Ernst’s department may be partly down to the charity’s official complaint about him after he publicly attacked its draft guide to complementary medicines as “outrageous and deeply flawed”.
In 2010, former fellows of Charles’ disgraced FIH launched a new organisation, The College of Medicine’ supporting the use of integrated treatments in the NHS. One director of the college is Michael Dixon, a GP in Cullompton, Devon, who was formerly medical director of the Foundation for Integrated Health. The others are George Lewith, who runs a complementary medicine unit at Southampton University; David Peters, the chairman of the British Holistic Medical Association; and Christine Glover, a holistic health consultant. All are former fellows of the prince’s charity. My own analysis of the activities of the new college leaves little doubt that it is promoting quackery.
In 2010, Charles published his book HARMONY which is full of praise for even the most absurd forms of quackery.
In 2011, after the launch of his very own range of herbal tinctures Charles was harshly criticised. Consequently, a public row was re-ignited with Clarence House by branding the Prince of Wales a “snake oil salesman”. I had the audacity to criticise the heir to the throne for lending his support to homeopathic remedies and for selling the Duchy Herbals detox tincture.
In 2011, Charles forged a link between ‘The College of Medicine’ and an Indian holistic health centre. The collaboration has been reported to include clinical training to European and Western doctors in ayurveda and homoeopathy and traditional forms of medicine to integrate them in their practice. The foundation stone for the extended campus of the Royal College known as the International Institution for Holistic and Integrated Medicine was laid by Dr Michael Dixon in collaboration with the Royal College of Medicine.
In 2012, Charles was nominated for ‘THE GOLDEN DUCK AWARD’ for his achievements in promoting quackery; Andrew Wakefield beat him to it, but Charles was a well-deserved runner-up.
In 2013, Charles called for society to embrace a broader and more complex concept of health. In his article he described a vision of health that includes the physical and social environment, education, agriculture and architecture. Emphasising that his point is not to confront accepted medical wisdom, HRH suggests reasons for encouraging a wider perspective on health. Rather than simply treating the symptoms of disease, The Prince advocates a health service that puts patients at the heart of the process by incorporating the core human elements of mind, body and spirit. Explaining that symptoms may often be a metaphor for underlying disease and unhappiness, he calls for a scientific and therapeutic approach that understands, values and uses patient perspective and belief rather than seeking to exclude them.
In 2013, Charles’ Highgrove enterprise offered ‘baby-hampers’ for sale at £195 a piece and made a range of medicinal claims for the products it contained. As these claims were not supported by evidence, there is no way to classify them other than quackery.
By 2013, the ‘Association of Osteomyologists’ are seeking to become regulated in statute, with the help of Prince Charles as their patron. An Osteomyologist will treat both the symptoms and the root cause of a condition with the aim of alleviating symptoms and preventing reoccurrence whenever possible. Osteomyology encourages the skilled use of techniques including Cranial and Cranio-Sacral therapy.
In November 2013, Charles invited alternative medicine proponents from across the world, including Dean Michael Ornish, Sausalito, California, Michael Dixon, chair of College of Medicine, UK and Issac Mathai of Soukya Foundation, Bangalore, to India for a ‘brain storm’ and a subsequent conference on alternative medicine. The prince wanted the experts to collaborate and explore the possibilities of integrating different systems of medicines and to better the healthcare delivery globally, one of the organisers said.
I am sure that, in the future, we will hear much more about Charles’ indulgence in quackery; and, of course, we will hear more criticism of it. But I doubt that anyone can put it better that the late Christopher Hitchens who repeatedly wrote about Charles’ passion for anti-science:
“Once the hard-won principles of reason and science have been discredited, the world will not pass into the hands of credulous herbivores who keep crystals by their sides and swoon over the poems of Khalil Gibran. The “vacuum” will be invaded instead by determined fundamentalists of every stripe who already know the truth by means of revelation and who actually seek real and serious power in the here and now. One thinks of the painstaking, cloud-dispelling labour of British scientists from Isaac Newton to Joseph Priestley to Charles Darwin to Ernest Rutherford to Alan Turing and Francis Crick, much of it built upon the shoulders of Galileo and Copernicus, only to see it causally slandered by a moral and intellectual weakling from the usurping House of Hanover.”
And perhaps even better here:
We have known for a long time that Prince Charles’ empty sails are so rigged as to be swelled by any passing waft or breeze of crankiness and cant. He fell for the fake anthropologist Laurens van der Post. He was bowled over by the charms of homeopathic medicine. He has been believably reported as saying that plants do better if you talk to them in a soothing and encouraging way. But this latest departure promotes him from an advocate of harmless nonsense to positively sinister nonsense….The heir to the throne seems to possess the ability to surround himself—perhaps by some mysterious ultramagnetic force?—with every moon-faced spoon-bender, shrub-flatterer, and water-diviner within range.
According to a recent comment by Dr Larry Dossey, sceptics are afflicted by “randomania,” “statisticalitis,” “coincidentitis,” or “ODD” (Obsessive Debunking Disorder). I thought his opinion was hilariously funny; it shows that this prominent apologist of alternative medicine who claims that he is deeply rooted in the scientific world has, in fact, understood next to nothing about the scientific method. Like all quacks who have run out of rational arguments, he resorts to primitive ad hominem attacks in order to defend his bizarre notions. It also suggests that he could do with a little scepticism himself, perhaps.
In case anyone wonders how the long-obsolete notions of vitalism, which Dossey promotes, not just survive but are becoming again wide-spread, they only need to look into the best-selling books of Dossey and other vitalists. And it is not just lay people, the target audience of such books, who are taken by such nonsense. Health care professionals are by no means immune to these remnants from the prescientific era.
A recent survey is a good case in point. It was aimed at exploring US student pharmacists’ attitudes toward complementary and alternative medicine (CAM) and examine factors shaping students’ attitudes. In total, 887 student pharmacists in 10 U.S. colleges/schools of pharmacy took part. Student pharmacists’ attitudes regarding CAM were quantified using the attitudes toward CAM scale (15 items), attitudes toward specific CAM therapies (13 items), influence of factors (e.g., coursework, personal experience) on attitudes (18 items), and demographic characteristics (15 items).
The results show a mean (±SD) score on the attitudes toward CAM scale of 52.57 ± 7.65 (of a possible 75; higher score indicated more favorable attitudes). There were strong indications that students agreed with the concepts of vitalism. When asked about specific CAMs, many students revealed positive views even on the least plausible and least evidence-based modalities like homeopathy or Reiki.
Unsurprisingly, students agreed that a patient’s health beliefs should be integrated in the patient care process and that knowledge about CAM would be required in future pharmacy practice. Scores on the attitudes toward CAM scale varied by gender, race/ethnicity, type of institution, previous CAM coursework, and previous CAM use. Personal experience, pharmacy education, and family background were important factors shaping students’ attitudes.
The authors concluded: Student pharmacists hold generally favorable views of CAM, and both personal and educational factors shape their views. These results provide insight into factors shaping future pharmacists’ perceptions of CAM. Additional research is needed to examine how attitudes influence future pharmacists’ confidence and willingness to talk to patients about CAM.
I find the overwhelmingly positive views of pharmacists on even over quackery quite troubling. One of the few critical pharmacists shares my worries and commented that this survey on CAM attitudes paints a concerning portrait of American pharmacy students. However, limitations in the survey process may have created biases that could have exaggerated the overall perspective presented. More concerning than the results themselves are the researchers’ interpretation of this data: Critical and negative perspectives on CAM seem to be viewed as problematic, rather than positive examples of good critical thinking.
One lesson from surveys like these is they illustrate the educational goals of CAM proponents. Just like “integrative” medicine that is making its ways into academic hospital settings, CAM education on campus is another tactic that is being used by proponents to shape health professional attitudes and perspectives early in their careers. The objective is obvious: normalize pseudoscience with students, and watch it become embedded into pharmacy practice.
Is this going to change? Unless there is a deliberate and explicit attempt to call out and push back against the degradation of academic and scientific standards created by existing forms of CAM education and “integrative medicine” programs, we should expect to see a growing normalizing of pseudoscience in health professions like pharmacy.
I have criticised pharmacists’ attitude and behaviour towards alternative medicine more often than I care to remember. I even contributed an entire series of articles (around 10; I forgot the precise number) to THE PHARMACEUTICAL JOURNAL in an attempt to stimulate their abilities to think critically about alternative medicine. Pharmacists could certainly do with a high dose of “randomania,” “statisticalitis,” “coincidentitis,” or “ODD” (Obsessive Debunking Disorder). In particular, pharmacists who sell bogus remedies, i.e. virtually all retail pharmacists, need to remember that
- they are breaking their own ethical code
- they are putting profit before responsible health care
- by selling bogus products, they give credibility to quackery
- they are risking their reputation as professionals who provide evidence-based advice to the public
- they might seriously endanger the health of many of their customers
In discussions about these issues, pharmacists usually defend themselves and argue that
- those working in retail chains cannot do anything about this situation; head office decides what is sold on their premises and what not
- many medicinal products we sell are as bogus as the alternative medicines in question
- other health care professions are also not perfect, blameless or free of fault and error
- many pharmacists, particularly those not working in retail, are aware of this lamentable situation but cannot do anything about it
- retail pharmacists are both shopkeepers and health care professionals and are trying their very best to cope with this difficult dual role
- we usually appreciate your work and critical comments but, in this case, you are talking nonsense
I do not agree with any of these arguments. Of course, each single individual pharmacist is fairly powerless when it comes to changing the system (but nobody forces anyone to work in a chain that breaks the ethical code of their profession). Yet pharmacists have their professional organisations, and it is up to each individual pharmacist to exert influence, if necessary pressure, via their professional bodies and representatives, such that eventually the system changes. In all this distasteful mess, only one thing seems certain: without a groundswell of opinion from pharmacists, nothing will happen simply because too many pharmacists are doing very nicely with fooling their customers into buying expensive rubbish.
And when eventually something does happen, it will almost certainly be a slow and long process until quackery has been fully expelled from retail pharmacies. My big concern is not so much the slowness of the process but the fact that, currently, I see virtually no groundswell of opinion that might produce anything. For the foreseeable future pharmacists seem to have decided to be content with a role as shopkeepers who do not sufficiently care about healthcare-ethics to change the status quo.
A recent article by a South African homeopath promoted the concept of homeopaths taking over the role of primary care practitioners. His argument essentially was that, in South Africa, homeopaths are well trained and thus adequately equipped to do this job responsibly. Responsibly, really? You find that hard to believe? Here are the essentials of his arguments including all his references in full. I think they are worth reading.
Currently, the Durban University of Technology (DUT) and the University of Johannesburg (UJ) offer degree’s in homoeopathy. This involves a 5-year full-time theoretical and practical training course, followed by a Master’s level research project. After fulfilment of these criteria, a Master’s Degree in Technology (Homoeopathy) is awarded. The course comprises of a strong core of medical subjects, such as the basic sciences of Anatomy, Physiology, Medical Microbiology, Biochemistry and Epidemiology, and the clinical sciences of Pathology and Diagnostics. This is complemented with subjects in Classical, Clinical and Modern Homoeopathy and Homoeopharmaceutics4,5…
By law, any person practicing homoeopathy in South Africa must be registered with the Allied Health Professions Council of South Africa (AHPCSA). This is essential, as the Council ensures both medical and homoeopathic competency of practitioners, and that the activities of registered practitioners are closely monitored by the Professional Board. The purpose of the AHPCSA is to ensure that only those with legitimate qualifications of a high enough standard are registered and allowed to practice in South Africa, thus protecting the public against any fraudulent behaviour and illegal practitioners. Therefore, in order to ensure effective homoeopathic treatment, it is essential that any person wishing to prescribe homoeopathic medicine or practice homoeopathy in South Africa must be registered as a Homoeopathic Practitioner with the Allied Health Professions Council of South Africa. This includes conventional Medical Practitioners (dual registration is allowed for Medical Practitioners with both the Health Professions Council and AHPCSA)6, as homoeopathy requires several years of training in order to apply effectively in clinical practice…
Registration with the Council affords medico-legal rights similar to those of a medical professional, where treatment is limited to the scope of homoeopathic practice. Thus a homoeopath is firstly a trained diagnostician, and with successful registration with the Council, obtains the title Doctor. A homoeopath is trained and legally obliged to conduct a full medical history, a comprehensive clinical examination, and request further medical investigations, such as blood tests and X-rays, in order to fully assess patients. This is coupled with the ability to consult with specialist pathologists and other medical specialists when necessary, and refer a patient to the appropriate practitioner if the condition falls outside the scope of homoeopathic practice. A homoeopath may also legally issue a certificate of dispensation (‘Doctor’s note’) with appropriate evidence and within reason, and is deemed responsible for the diagnosis and treatment of patients under their care6. A homoeopath is not trained or licensed in any form of surgery, specialist diagnostics (e.g. colonoscopy or angiograms), cannot prescribe prescription medication and is not lawfully allowed to conduct intra-venous treatment of any kind. However, a registered homoeopath is licensed to use intra-muscular homoeopathic injectables in the treatment of various local or systemic complaints when necessary.
Conventional (allopathic) medicine generally targets specific biochemical processes with mostly chemically synthesised medication, in an attempt to suppress a symptom. However, in doing so, this usually negatively affects other biochemical reactions which results in an imbalance within the system. Homoeopathy, by contrast, seeks to re-establish a balance within the natural functioning of the body, restore proper function and results in the reduction or cessation of symptoms. Homoeopathy therefore enables the body to self-regulate and self-heal, a process known as homeostasis that is intrinsic to every living organism.
Conventional medical treatment is by no means risk free. Iatrogenic (medically induced) deaths in the United States are estimated at 786 000 per year, deaths which are considered avoidable by medical doctors7,8. These figures put annual iatrogenic death in the American medical system above that of cardiovascular disease and cancer as the leading cause of death in that country9, a fact that is not widely reported! South African figures are not easily available, but it is likely that we have similar rates. Although conventional medications have a vital role, are sometimes necessary and can of-course be life-saving, all too often too many patients are put on chronic medication when there are numerous effective, natural, safe and scientifically substantiated options available….
According to the World Health Organisation (WHO), homeopathy is the second largest system of medicine in the world, and world-wide use continues to grow in developed and developing nations10. Homoeopathy is widely considered to be safe and effective, with both clinical and laboratory research providing evidence for the efficacy of homoeopathy11. As the range of potential conditions that homoeopathy can treat is almost limitless, and that treatment is not associated with adverse reactions, homoeopathy should be considered a first-line therapy for all ages. As homoeopaths in South Africa are considered primary health care practitioners, if a conventional approach is deemed necessary, and further diagnostics are required, your practitioner will not hesitate to refer you to the appropriate health care practitioner. Homeopathy is also used alongside conventional medicine and any other form of therapy, and should be seen as ‘complementary’ medicine and not ‘alternative’ medicine.
Homoeopathy is an approach that is widely considered to be safe, and when utilised correctly, can be effective for a wide range of conditions. As a primary health care practitioner, a homoeopath is able to handle all aspects of general practice and family health care, including diagnostics, case management and referral to other practitioners or medical specialists. A registered homoeopath is legally responsible to ensure the adequate treatment of their patients, and is accountable for all clinical decisions and advice. A registered homoeopath understands the role of conventional medicine, and will refer to the appropriate specialist in cases that fall outside the legal scope of practice.

I found this article extremely revealing and scary. It gives us an important glimpse into the way some or perhaps even most homeopaths think. They clearly believe that:
1) Their training is sufficient for them to become competent primary care professionals, i.e. clinicians who are the first port of call for sick people to be diagnosed and treated effectively.
2) Homeopathy is scientifically proven to be efficacious for an ‘almost limitless’ range of conditions. Interestingly, not a single reference is provided to support this claim. Nevertheless, homeopath believe it, and that seems to be enough.
3) Homeopaths seem convinced that they perfectly understand real medicine; yet all they really do is to denounce it as one of the biggest killer of mankind.
4) The fact that homeopaths cannot prescribe real medicine is not seen as a hindrance to their role as primary care practitioner; if anything, homeopaths consider this to be an advantage.
5) Homeopaths view registration with some sort of governing body as the ultimate legitimation of their trade. Once such regulatory measures are in place, the need to support any of their claims with evidence is nil and void.
This article did remind me of the wry statement that ‘HOMEOPATHY IS TO MEDICINE WHAT THE CARPET INDUSTRY IS TO AVIATION’. Homeopaths truly live on a different planet, a planet where belief is everything and responsibility is an alien concept. I certainly hope that they will not take over planet earth in a hurry. If I imagine a world where homeopaths dominate primary care in the way it is suggested in this article, I start having nightmares. It seems to me that people who harbour ideas of this type are not just deluded to the point of madness but they are a danger to public health.
The following is a guest post by Preston H. Long. It is an excerpt from his new book entitled ‘Chiropractic Abuse—A Chiropractor’s Lament’. Preston H. Long is a licensed chiropractor from Arizona. His professional career has spanned nearly 30 years. In addition to treating patients, he has testified at about 200 trials, performed more than 10,000 chiropractic case evaluations, and served as a consultant to several law enforcement agencies. He is also an associate professor at Bryan University, where he teaches in the master’s program in applied health informatics. His new book is one of the very few that provides an inside criticism of chiropractic. It is well worth reading, in my view.
Have you ever consulted a chiropractor? Are you thinking about seeing one? Do you care whether your tax and health-care dollars are spent on worthless treatment? If your answer to any of these questions is yes, there are certain things you should know.
1. Chiropractic theory and practice are not based on the body of knowledge related to health, disease, and health care that has been widely accepted by the scientific community.
Most chiropractors believe that spinal problems, which they call “subluxations,” cause ill health and that fixing them by “adjusting” the spine will promote and restore health. The extent of this belief varies from chiropractor to chiropractor. Some believe that subluxations are the primary cause of ill health; others consider them an underlying cause. Only a small percentage (including me) reject these notions and align their beliefs and practices with those of the science-based medical community. The ramifications and consequences of subluxation theory will be discussed in detail throughout this book.
2. Many chiropractors promise too much.
The most common forms of treatment administered by chiropractors are spinal manipulation and passive physiotherapy measures such as heat, ultrasound, massage, and electrical muscle stimulation. These modalities can be useful in managing certain problems of muscles and bones, but they have little, if any, use against the vast majority of diseases. But chiropractors who believe that “subluxations” cause ill health claim that spinal adjustments promote general health and enable patients to recover from a wide range of diseases. The illustrations below reflect these beliefs. The one to the left is part of a poster that promotes the notion that periodic spinal “adjustments” are a cornerstone of good health. The other is a patient handout that improperly relates “subluxations” to a wide range of ailments that spinal adjustments supposedly can help. Some charts of this type have listed more than 100 diseases and conditions, including allergies, appendicitis, anemia, crossed eyes, deafness, gallbladder problems, hernias, and pneumonia.
A 2008 survey found that exaggeration is common among chiropractic Web sites. The researchers looked at the Web sites of 200 chiropractors and 9 chiropractic associations in Australia, Canada, New Zealand, the United Kingdom, and the United States. Each site was examined for claims suggesting that chiropractic treatment was appropriate for asthma, colic, ear infection/earache/otitis media, neck pain, whiplash, headache/migraine, and lower back pain. The study found that 95% of the surveyed sites made unsubstantiated claims for at least one of these conditions and 38% made unsubstantiated claims for all of them.1 False promises can have dire consequences to the unsuspecting.
3. Our education is vastly inferior to that of medical doctors.
I rarely encountered sick patients in my school clinic. Most of my “patients” were friends, students, and an occasional person who presented to the student clinic for inexpensive chiropractic care. Most had nothing really wrong with them. In order to graduate, chiropractic college students are required to treat a minimum number of people. To reach their number, some resort to paying people (including prostitutes) to visit them at the college’s clinic.2
Students also encounter a very narrow range of conditions, most related to aches and pains. Real medical education involves contact with thousands of patients with a wide variety of problems, including many severe enough to require hospitalization. Most chiropractic students see patients during two clinical years in chiropractic college. Medical students also average two clinical years, but they see many more patients and nearly all medical doctors have an additional three to five years of specialty training before they enter practice.
Chiropractic’s minimum educational standards are quite low. In 2007, chiropractic students were required to evaluate and manage only 15 patients in order to graduate. Chiropractic’s accreditation agency ordered this number to increase to 35 by the fall of 2011. However, only 10 of the 35 must be live patients (eight of whom are not students or their family members)! For the remaining cases, students are permitted to “assist, observe, or participate in live, paper-based, computer-based, distance learning, or other reasonable alternative.”3 In contrast, medical students see thousands of patients.
Former National Council Against Health Fraud President William T. Jarvis, Ph.D., has noted that chiropractic school prepares its students to practice “conversational medicine”—where they glibly use medical words but lack the knowledge or experience to deal appropriately with the vast majority of health problems.4 Dr. Stephen Barrett reported a fascinating example of this which occurred when he visited a chiropractor for research purposes. When Barrett mentioned that he was recovering from an attack of vertigo (dizziness), the chiropractor quickly rattled off a textbook-like list of all the possible causes. But instead of obtaining a proper history and conducting tests to pinpoint a diagnosis, he x-rayed Dr. Barrett’s neck and recommended a one-year course of manipulations to make his neck more curved. The medical diagnosis, which had been appropriately made elsewhere, was a viral infection that cleared up spontaneously in about ten days.5
4. Our legitimate scope is actually very narrow.
Appropriate chiropractic treatment is relevant only to a narrow range of ailments, nearly all related to musculoskeletal problems. But some chiropractors assert that they can influence the course of nearly everything. Some even offer adjustments to farm animals and family pets.
5. Very little of what chiropractors do has been studied.
Although chiropractic has been around since 1895, little of what we do meets the scientific standard through solid research. Chiropractic apologists try to sound scientific to counter their detractors, but very little research actually supports what chiropractors do.
6. Unless your diagnosis is obvious, it’s best to get diagnosed elsewhere.
During my work as an independent examiner, I have encountered many patients whose chiropractor missed readily apparent diagnoses and rendered inappropriate treatment for long periods of time. Chiropractors lack the depth of training available to medical doctors. For that reason, except for minor injuries, it is usually better to seek medical diagnosis first.
7. We offer lots of unnecessary services.
Many chiropractors, particularly those who find “subluxations” in everyone, routinely advise patients to come for many months, years, and even for their lifetime. Practice-builders teach how to persuade people they need “maintenance care” long after their original problem has resolved. In line with this, many chiropractors offer “discounts” to patients who pay in advance and sign a contract committing them for 50 to 100 treatments. And “chiropractic pediatric specialists” advise periodic examinations and spinal adjustments from early infancy onward. (This has been aptly described as “womb to tomb” care.) Greed is not the only factor involved in overtreatment. Many who advise periodic adjustments are “true believers.” In chiropractic school, one of my classmates actually adjusted his newborn son while the umbilical cord was still attached. Another student had the school radiology department take seven x-rays of his son’s neck to look for “subluxations” presumably acquired during the birth process. The topic of unnecessary care is discussed further in Chapter 8.
8. “Cracking” of the spine doesn’t mean much.
Spinal manipulation usually produces a “popping” or “cracking” sound similar to what occurs when you crack your knuckles. Both are due to a phenomenon called cavitation, which occurs when there is a sudden decrease in joint pressure brought on by the manipulation. That allows dissolved gasses in the joint fluid to be released into the joint itself. Chiropractors sometimes state that the noise means that something therapeutic has taken place. However, the noise has no health-related significance and does not indicate that anything has been realigned. It simply means that gas was allowed to escape under less pressure than normal. Knuckles do not “go back into place” when you crack them, and neither do spinal bones.
9. If the first few visits don’t help you, more treatment probably won’t help.
I used to tell my patients “three and through.” If we did not see significant objective improvement in three visits, it was time to move on.
10. We take too many x-rays.
No test should be done unless it is likely to provide information that will influence clinical management of the patient. X-ray examinations are appropriate when a fracture, tumor, infection, or neurological defect is suspected. But they are not needed for evaluating simple mechanical-type strains, such as back or neck pain that develops after lifting a heavy object.
The average number of x-rays taken during the first visit by chiropractors whose records I have been asked to review has been about eleven. Those records were sent to me because an insurance company had flagged them for investigation into excessive billing, so this number of x-rays is much higher than average. But many chiropractors take at least a few x-rays of everyone who walks through their door.
There are two main reasons why chiropractors take more x-rays than are medically necessary. One is easy money. It costs about 35¢ to buy an 8- x 10-inch film, for which they typically charge $40. In chiropractic, the spine encompasses five areas: the neck, mid-back, low-back, pelvic, and sacral regions. That means five separate regions to bill for—typically three to seven views of the neck, two to six for the low back, and two for each of the rest. So eleven x-ray films would net the chiropractor over $400 for just few minutes of work. In many accident cases I have reviewed, the fact that patients had adequate x-ray examinations in a hospital emergency department to rule out fractures did not deter the chiropractor from unnecessarily repeating these exams.
Chiropractors also use x-ray examinations inappropriately for marketing purposes. Chiropractors who do this point to various things on the films that they interpret as (a) subluxations, (b) not enough spinal curvature, (c) too much spinal curvature, and/or (d) “spinal decay,” all of which supposedly call for long courses of adjustments with periodic x-ray re-checks to supposedly assess progress. In addition to wasting money, unnecessary x-rays entail unnecessary exposure to the risks of ionizing radiation.
11. Research on spinal manipulation does not reflect what takes place in most chiropractic offices.
Research studies that look at spinal manipulation are generally done under strict protocols that protect patients from harm. The results reflect what happens when manipulation is done on patients who are appropriately screened—usually by medical teams that exclude people with conditions that would make manipulation dangerous. The results do not reflect what typically happens when patients select chiropractors on their own. The chiropractic marketplace is a mess because most chiropractors ignore research findings and subject their patients to procedures that are unnecessary and/or senseless.
12. Neck manipulation is potentially dangerous.
Certain types of chiropractic neck manipulation can damage neck arteries and cause a stroke. Chiropractors claim that the risk is trivial, but they have made no systematic effort to actually measure it. Chapter 9 covers this topic in detail.
13. Most chiropractors don’t know much about nutrition.
Chiropractors learn little about clinical nutrition during their schooling. Many offer what they describe as “nutrition counseling.” But this typically consists of superficial advice about eating less fat and various schemes to sell you supplements that are high-priced and unnecessary.
14. Chiropractors who sell vitamins charge much more than it costs them.
Chiropractors who sell vitamins typically recommend them unnecessarily and charge two to three times what they pay for them. Some chiropractors center their practice around selling vitamins to patients. Their recommendations are based on hair analysis, live blood analysis, applied kinesiology muscle-testing or other quack tests that will be discussed later in this book. Patients who are victimized this way typically pay several dollars a day and are encouraged to stay on the products indefinitely. In one case I investigated, an Arizona chiropractor advised an 80+-year-old grandma to charge more than $10,000 for vitamins to her credit cards to avoid an impending stroke that he had diagnosed by testing a sample of her pubic hair. No hair test can determine that a stroke is imminent or show that dietary supplements are needed. Doctors who evaluated the woman at the Mayo Clinic found no evidence to support the chiropractor’s assessment.
15. Chiropractors have no business treating young children.
The pediatric training chiropractors receive during their schooling is skimpy and based mainly on reading. Students see few children and get little or no experience in diagnosing or following the course of the vast majority of childhood ailments. Moreover, spinal adjustment has no proven effectiveness against childhood diseases. Some adolescents with spinal stiffness might benefit from manipulation, but most will recover without treatment. Chiropractors who claim to practice “chiropractic pediatrics” typically aim to adjust spines from birth onward and are likely to oppose immunization. Some chiropractors claim they can reverse or lessen the spinal curvature of scoliosis, but there is no scientific evidence that spinal manipulation can do this.6
16. The fact that patients swear by us does not mean we are actually helping them.
Satisfaction is not the same thing as effectiveness. Many people who believe they have been helped had conditions that would have resolved without treatment. Some have had treatment for dangers that did not exist but were said by the chiropractor to be imminent. Many chiropractors actually take courses on how to trick patients to believe in them. (See Chapter 8)
17. Insurance companies don’t want to pay for chiropractic care.
Chiropractors love to brag that their services are covered by Medicare and most insurance companies. However, this coverage has been achieved though political action rather than scientific merit. I have never encountered an insurance company that would reimburse for chiropractic if not forced to do so by state laws. The political pressure to mandate chiropractic coverage comes from chiropractors, of course, but it also comes from the patients whom they have brainwashed.
18. Lots of chiropractors do really strange things.
The chiropractic profession seems to attract people who are prone to believe in strange things. One I know of does “aura adjustments” to treat people’s “bruised karma.” Another rents out a large crystal to other chiropractors so they can “recharge” their own (smaller) crystals. Another claims to get advice by “channeling” a 15th Century Scottish physician. Another claimed to “balance a woman’s harmonics” by inserting his thumb into her vagina and his index finger into her anus. Another treated cancer with an orange light that was mounted in a wooden box. Another did rectal exams on all his female patients. Even though such exams are outside the legitimate scope of chiropractic, he also videotaped them so that if his bills for this service were questioned, he could prove that he had actually performed what he billed for.
19. Don’t expect our licensing boards to protect you.
Many chiropractors who serve on chiropractic licensing boards harbor the same misbeliefs that are rampant among their colleagues. This means, for example, that most boards are unlikely to discipline chiropractors for diagnosing and treating imaginary “subluxations.”
20. The media rarely look at what we do wrong.
The media rarely if ever address chiropractic nonsense. Reporting on chiropractic is complicated because chiropractors vary so much in what they do. (In fact, a very astute observer once wrote that “for every chiropractor, there is an equal and opposite chiropractor.”) Consumer Reports published superb exposés in 1975 and 1994, but no other print outlet has done so in the past 35 years. This lack of information is the main reason I have written this book.

In 1747, James Lind conducted what may well be the first documented controlled clinical trial in the history of medicine. He treated a small group of healthy sailors with a range of different remedies to see whether one of these regimen might be effective in preventing scurvy. The results showed that lemon and lime juice – effectively vitamin C – did the trick. This trial changed the world: it saved tens of thousands of lives, gave Britain the advantage at sea needed to become a dominant empire, and set medicine on the track to eventually become evidence-based.
Of course, Lind did not know that the effective principle in his lemon/lime juice was vitamin C. The Hungarian physiologist Albert Szent-Gyorgyi discovered vitamin C only ~200 years later and received the Nobel Prize for it in 1937. Since then, research has been buoyant, and vitamin C has been advocated for almost every condition one can think of. Looking at some of the claims made for it, I get the impression that more charlatans have jumped on the vitamin C band-waggon than the old vehicle can support. In alternative medicine, high-dose IV vitamin C is a popular variation of Lind’s concept, not least for the treatment of cancer.
Researchers from the NIH in the US surveyed attendees at annual CAM Conferences in 2006 and 2008, and determined sales of intravenous vitamin C by major U.S. manufacturers/distributors. They also queried practitioners for adverse effects, compiled published cases, and analyzed FDA’s Adverse Events Database. Of 199 survey respondents (out of 550), 172 practitioners had administered IV vitamin C to 11,233 patients in 2006 and to 8876 patients in 2008. The average dose was 28 grams every 4 days, with a mean of 22 treatments per patient. Estimated yearly doses used (as 25g/50ml vials) were 318,539 in 2006 and 354,647 in 2008. Manufacturers’ yearly sales were 750,000 and 855,000 vials, respectively. Common reasons for treatment included infection, cancer, and fatigue. Of 9,328 patients for whom data was available, 101 had adverse effects, mostly minor, including lethargy/fatigue in 59 patients, change in mental status in 21 patients and vein irritation/phlebitis in 6 patients. Publications documented serious adverse events, including two deaths. The FDA Adverse Events Database was uninformative.
The authors of this paper conclude that high dose IV vitamin C is in unexpectedly wide use by CAM practitioners. Other than the known complications of IV vitamin C in those with renal impairment or glucose 6 phosphate dehydrogenase deficiency, high dose intravenous vitamin C appears to be remarkably safe. Physicians should inquire about IV vitamin C use in patients with cancer, chronic, untreatable, or intractable conditions and be observant of unexpected harm, drug interactions, or benefit.
I find these results somewhat worrying. Desperate cancer patients are constantly being told that they can fight the disease with high-dose vitamin C, for instance on the >9 million (!) websites on this subject. One site, for instance, leaves little doubt about the efficacy of vitamin C as a treatment for cancer: First shown to be a powerful anti-cancer agent in 1971, it wasn’t until 20 years later that vitamin C started to be accepted by the mainstream medical profession. Eating a vitamin C-rich diet substantially reduces the risk of cancer, and high intakes – above 5000mg a day (the equivalent of 100 oranges) – substantially increases the life expectancy of cancer patients.
Statements like this one give false hope to cancer patients which is unethical and cruel and might hasten the death of many. The reality is quite different and provides little reason for such hope. Here are just a few conclusions from recent scientific analyses on this or closely related topics:
We could not find evidence that antioxidant supplements prevent gastrointestinal cancers. On the contrary, they seem to increase overall mortality. The potential cancer preventive effect of selenium should be studied in adequately conducted randomised trial
The question whether the regular intake of high doses of vitamin C have a preventative effect for certain cancers is currently open. But there is no good reason to suggest that high dose IV vitamin C is an effective treatment for any cancer. To pretend otherwise, as so many alternative practitioners seem to do, is less than responsible – in fact, it is a hallmark for cancer quackery.
This post was inspired by a shiatsu-practitioner who recently commented on this blog. As I have not yet written a post about shiatsu, I think this might be a good occasion to do so. On one of the websites of the said practitioner – who claimed to have such amazing powers that he “would be locked up or worse“, if he made them public – explains that Shiatsu is a form of natural healing therapy that promotes health through finger pressure along energy meridians or channels – like acupuncture but with no needles and all your clothes on. Shiatsu is a combination of ancient theories of oriental medicine and ‘energy’, with modern knowledge of anatomy and physiology. Shiatsu originated in Japan where it is officially recognised and parents teach their children to treat them. Shiatsu is one of the fastest growing areas of complementary therapy in the UK. Shiatsu is safe and non-invasive. Shiatsu is a holistic therapy which means your whole body is treated. Work on your energy channels promotes well-being at the physical and emotional levels and stimulates your natural self-healing processes. The application of pressure and gentle stretching helps relieve muscle tension, joint stiffness and to realign body structures. Contact with the energy pathways helps to correct imbalance in the functioning of internal organs and to re-balance the effects of emotional disturbance. You don’t have to be ill to enjoy Shiatsu, many people enjoy it simply because it is deeply relaxing.
I also looked up another of his websites and found that he claims to treat the following conditions:
- Anger Management
- Anxiety and Stress
- Back pain
- Bipolar disorder
- Breathing/respiratory problems
- Confidence issues
- Digestive Disorders
- Eating Disorders
- Emotional Issues
- Fears and Phobias
- Irritable bowel syndrome (IBS)
- Joint Pain
- Low energy/Lethargy
- Low Self-Esteem
- ME/Chronic Fatigue Syndrome
- Muscular Tension
- Nausea and sickness
- Panic Attacks
- Sexual problems
- Sinus problems
- Skin conditions
- Sleeping problems
- Social anxiety disorder
- Spiritual Issues
- Weight problems
Impressed by this list, I looked at similar sites and found that such extravagant claims seem more the rule than the exception in the world of shiatsu. Such therapeutic claims came as a big surprise to me: the last time we reviewed the evidence, we had concluded: NO CONVINCING DATA AVAILABLE TO SUGGEST THAT SHIATSU IS EFFECTIVE FOR ANY CONDITION.
But that was 5 years ago; perhaps there have been major advances since? To find out, I did a quick Medline search and – BINGO! – found a recent systematic review entitled “The evidence for Shiatsu: a systematic review of Shiatsu and acupressure“. It was authored by proponents of this therapy and can therefore not be suspected to be riddled with ‘anti-shiatsu bias’ (I just love the give-away title THE EVIDENCE FOR SHIATSU….!). These authors found that “Shiatsu studies comprised 1 RCT, three controlled non-randomised, one within-subjects, one observational and 3 uncontrolled studies investigating mental and physical health issues. Evidence was of insufficient quantity and quality” The only RCT included in their review was not actually a study of shiatsu but of a complex mixture of treatments including shiatsu for back and neck pain. No significant effects compared to standard care were identified in this study.
So, what does that tell us about shiatsu? It clearly tells us that it is an unproven therapy. And what does that say about shiatsu-practitioners who make multiple claims about treating serious conditions? I think I can leave it to my readers to answer this question.
As I write these words, I am travelling back from a medical conference. The organisers had invited me to give a lecture which I concluded saying: “anyone in medicine not believing in evidence-based health care is in the wrong business”. This statement was meant to stimulate the discussion and provoke the audience who were perhaps just a little on the side of those who are not all that taken by science.
I may well have been right, because, in the coffee break, several doctors disputed my point; to paraphrase their arguments: “You don’t believe in the value of experience, you think that science is the way to know everything. But you are wrong! Philosophers and other people, who are a lot cleverer than you, tell us that science is not the way to real knowledge; and in some forms of medicine we have a wealth of experience which we cannot ignore. This is at least as important as scientific knowledge. Take TCM, for instance, thousands of years of tradition must mean something; in fact it tells us more than science will ever be able to. Qi-energy, for instance, is a concept based on experience, and science is useless at verifying it.”
I disagreed, of course. But I am afraid that I did not convince my colleagues. The appeal to tradition is amazingly powerful, so much so that even well-seasoned physicians fall for it. Yet it nevertheless is a fallacy, I am sure.
So what does experience tell us, how is it generated and why should it be unreliable?
On the level of the individual, experience emerges when a clinician makes similar observations several times in a row. This is so persuasive that few doctors are immune to the phenomenon. Let’s assume the experience is about acupuncture, more precisely about acupuncture for smoking cessation. The acupuncturist presumably has learnt during his training that his therapy works for that indication via stimulating the flow of Qi, and promptly tries it on several patients. Some of them come back for more and report that they find it easier to give up cigarettes after consulting him. This happens repeatedly, and our clinician forthwith is convinced – in fact, he knows – that acupuncture is effective for smoking cessation.
If we critically analyse this scenario, what does it tell us? It tells us very little of relevance, I am afraid. The scenario is entirely compatible with a whole host of explanations which have nothing to do with the effects of acupuncture per se:
- Those patients who did not manage to stop smoking might not have returned. Only seeing his successes without his failures, the acupuncturist would have got the wrong end of the stick.
- Human memory is selective such that the few patients who did come back and reported failure might easily get forgotten by the clinician. We all remember the good things and forget the disappointments, particularly if we are clinicians.
- The placebo-effect might have played a dirty trick on the experience of our acupuncturist.
- Some patients might have used nicotine patches that helped him to stop smoking without disclosing this fact to the acupuncturist who then, of course, attributed the benefit to his needling.
- The acupuncturist – being a very kind and empathetic clinician – might have involuntarily induced some of his patients to show kindness in return and thus tell porkies about their smoking habits which would have created a false positive impression about the effectiveness of his treatment.
- Being so empathetic, the acupuncturists would have provided lots of encouragement to stop smoking which, in some patients, might have been sufficient to kick the habit.
The long and short of all this is that our acupuncturist gradually got convinced by this interplay of factors that Qi exists and that acupuncture is an ineffective treatment. Hence forth he would bet his last shirt that he is right about this – after all, he has seen it with his own eyes, not just once but many times. And he will doubt anyone who shows him evidence that says otherwise. In fact, he is likely become very sceptical about scientific evidence in general – just like the doctors who talked to me after my lecture.
On a population level, such experience will be prevalent in not just one but most acupuncturists. Our clinician’s experience is certainly not unique; others will have made it too. In fact, as an acupuncturist, it is hard not to make it. Acupuncturists would have told everyone else about it, perhaps reported it on conferences or published it in articles or books. Experience of this nature is passed on from generation to generation, and soon someone will be able to demonstrate that acupuncture has been used ’effectively’ for smoking cessation since decades or centuries. The creation of a myth out of unreliable experience is thus complete.
Am I saying that experience of this nature is always and necessarily wrong or useless? No, I am not. It can be and often is correct. But, at the same time, it is frequently incorrect. It can serve as a valuable indicator but not more. Experience is not a tool for reliably informing us about the effectiveness of medical interventions. Experience based-medicine is an obsolete pseudo-medicine burdened with concepts that are counter-productive to optimal health care.
Philosophers and other people who are much cleverer than I am have been trying for some time to separate good from bad science and evidence from experience. Most recently, two philosophers, MASSIMO PIGLIUCCI and MAARTEN BOUDRY, commented specifically on this problem in relation to TCM. I leave you with some extensive quotes from what they wrote.
… pointing out that some traditional Chinese remedies (like drinking fresh turtle blood to alleviate cold symptoms) may in fact work, and therefore should not be dismissed as pseudoscience… risks confusing the possible effectiveness of folk remedies with the arbitrary theoretical-metaphysical baggage attached to it. There is no question that some folk remedies do work. The active ingredient of aspirin, for example, is derived from willow bark…
… claims about the existence of “Qi” energy, channeled through the human body by way of “meridians,” though, is a different matter. This sounds scientific, because it uses arcane jargon that gives the impression of articulating explanatory principles. But there is no way to test the existence of Qi and associated meridians, or to establish a viable research program based on those concepts, for the simple reason that talk of Qi and meridians only looks substantive, but it isn’t even in the ballpark of an empirically verifiable theory.
…the notion of Qi only mimics scientific notions such as enzyme actions on lipid compounds. This is a standard modus operandi of pseudoscience: it adopts the external trappings of science, but without the substance.
…The notion of Qi, again, is not really a theory in any meaningful sense of the word. It is just an evocative word to label a mysterious force of which we do not know and we are not told how to find out anything at all.
Still, one may reasonably object, what’s the harm in believing in Qi and related notions, if in fact the proposed remedies seem to help? Well, setting aside the obvious objections that the slaughtering of turtles might raise on ethical grounds, there are several issues to consider. To begin with, we can incorporate whatever serendipitous discoveries from folk medicine into modern scientific practice, as in the case of the willow bark turned aspirin. In this sense, there is no such thing as “alternative” medicine, there’s only stuff that works and stuff that doesn’t.
Second, if we are positing Qi and similar concepts, we are attempting to provide explanations for why some things work and others don’t. If these explanations are wrong, or unfounded as in the case of vacuous concepts like Qi, then we ought to correct or abandon them. Most importantly, pseudo-medical treatments often do not work, or are even positively harmful. If you take folk herbal “remedies,” for instance, while your body is fighting a serious infection, you may suffer severe, even fatal, consequences.
…Indulging in a bit of pseudoscience in some instances may be relatively innocuous, but the problem is that doing so lowers your defenses against more dangerous delusions that are based on similar confusions and fallacies. For instance, you may expose yourself and your loved ones to harm because your pseudoscientific proclivities lead you to accept notions that have been scientifically disproved, like the increasingly (and worryingly) popular idea that vaccines cause autism.
Philosophers nowadays recognize that there is no sharp line dividing sense from nonsense, and moreover that doctrines starting out in one camp may over time evolve into the other. For example, alchemy was a (somewhat) legitimate science in the times of Newton and Boyle, but it is now firmly pseudoscientific (movements in the opposite direction, from full-blown pseudoscience to genuine science, are notably rare)….
The borderlines between genuine science and pseudoscience may be fuzzy, but this should be even more of a call for careful distinctions, based on systematic facts and sound reasoning. To try a modicum of turtle blood here and a little aspirin there is not the hallmark of wisdom and even-mindedness. It is a dangerous gateway to superstition and irrationality
