For ‘my’ journal FACT, I review all the new articles that have emerged on the subject of alternative medicine on a monthly basis. Here are a few impressions and concerns that this activity have generated:
- The number of papers on alternative medicine has increased beyond belief: between the year 2000 and 2010, there was a slow, linear increase from 335 to 610 Medline-listed articles; thereafter, the numbers exploded to 1189 (2011), 1674 (2012) and 2236 (2013).
- This fast growing and highly lucrative ‘market’ has been cornered mainly by one journal: ‘EVIDENCE BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE’ (EBCAM), a journal that I mentioned several times before (see here, for instance). In 2010, EBCAM published 76 papers, while these figures increased to 546, 880 and 1327 during the following three years.
- Undeniably, this is big business, as authors have to pay tidy sums each time they get published in EBCAM.
- The peer-review system of EBCAM is farcical: potential authors who send their submissions to EBCAM are invited to suggest their preferred reviewers who subsequently are almost invariably appointed to do the job. It goes without saying that such a system is prone to all sorts of serious failures; in fact, this is not peer-review at all, in my opinion, it is an unethical sham.
- As a result, most (I estimate around 80%) of the articles that currently get published on alternative medicine are useless rubbish. They tend to be either pre-clinical investigations which never get followed up and are thus meaningless, or surveys of no relevance whatsoever, or pilot studies that never are succeeded by more definitive trials, or non-systematic reviews that are wide open to bias and can only mislead the reader.
- Nowadays, very few articles on alternative medicine are good enough to get published in mainstream journals of high standing.
The consequences of these fairly recent developments are serious:
- Conventional scientists and clinicians must get the impression that there is little research activity in alternative medicine (while, in fact, there is lots) and that the little research that does emerge is of poor quality.
- Consequently alternative medicine will be deemed by those who are not directly involved in it as trivial, and the alternative medicine journals will be ignored or even become their laughing stock.
- At the same time, the field of alternative medicine and its proponents (the only ones who might actually be reading the plethora of rubbish published in alternative medicine journals) will get more and more convinced that their field is supported by an ever- abundance of peer-reviewed, robust science.
- Gradually, they will become less and less aware of the standards and requirements that need to be met for evidence to be called reliable (provided they ever had such knowledge in the first place).
- They might thus get increasingly frustrated by the lack of acceptance of their ‘advances’ by proper scientists – an attitude which, from their perspective, must seem unfair, biased and hostile.
- In the end, conventional and alternative medicine, rather than learning from each other, will move further and further apart.
- Substantial amounts of money will continue to be wasted for research into alternative medicine that, whenever assessed critically, turns out to be too poor to advance healthcare in any meaningful way.
- The ones who medicine should be all about, namely the patients who need our help and rely on the progress of research, are not well served by these developments.
In essence this suggests, I think, that alternative medicine is ill-advised and short-sighted to settle for standards that are so clearly below those generally deemed acceptable in medicine. Similarly, conventional medicine does a serious disfavour to progress and to us all, if it ignores or tolerates this process.
I am not at all sure how to reverse this trend. In the long-term, it would require a change of attitude that obviously is far from easy to bring about. In the short-term, it might help, I think, to de-list journals from Medline that are in such obvious conflict with publication ethics.
Necessity, they say, is the mother of invention. The meaning of this proverb is fairly clear:
- In the Oxford Dictionary the proverb has been defined as– when the need for something becomes imperative, you are forced to find ways of getting or achieving it.
- According to the Cambridge Dictionary, this is “an expression that means that if you really need to do something, you will think of a way of doing it.”
- Finally, the Longman dictionary has defined the proverb as– “if someone really needs to do something, they will find a way of doing it.”
In the world of chiropractic the proverb acquires a special meaning: chiropractic relies almost entirely on inventions. A few examples have to suffice:
- first, instead of pathophysiology, they invented subluxations,
- this required the invention of adjustments which were needed for their imagined subluxation,
- then they invented the ‘inate’,
- then they invented the idea that all sorts of conditions are caused by subluxations and therefore require adjustments,
- finally, they invented the notion that regular adjustments are needed for a healthy person to stay healthy.
I was reminded of the unique inventive capacity of chiropractic when I came across the website of the Foundation for Chiropractic Progress (F4CP). The F4CP is, according to their own statements, a not-for-profit organization dedicated to raising awareness about the value of chiropractic care (which is, of course, another invention).
Experts at the F4CP point out that a growing number of professional athletic teams utilize chiropractic care to maximize overall health and maintain peak performance. “Repetitive motion injuries, including shoulder tendinitis, elbow, lower back pain and muscle spasms, are common conditions and injuries among professional baseball players that can be successfully prevented, managed and treated with chiropractic care,” says Hirad N. Bagy, DC. “Chiropractic adjustments, in conjunction with soft tissue mobilization, provide athletes with proper structure, function and balance to reduce the risk of injury, accelerate recovery time and improve overall performance,” he continues – and he must know, because he has received specialized training and certifications specific to sports medicine, which include the Graston Technique®, Active Release Technique®, Myofascial Release Technique, Impact Concussion Testing and Functional Dry Needling. Dr. Bagy continues: “A number of athletes that I treat regularly understand the importance of chiropractic maintenance care, and also seek treatment when an injury arises. Through the restoration of proper bio-mechanics, doctors of chiropractic are now positioned as key health care providers throughout all of the sports teams that I work with.”
BRAVO! We are impressed! So much so, that we almost forgot to ask: “Is there any evidence for all of these therapeutic claims?”
Just as well! Because had we asked and perhaps even did a bit of research, we would have found that almost none of these far-reaching claims are evidence-based.
But who would be so petty? Instead of criticising the incessant flow of bogus claims made by chiropractors worldwide, we should really admire their remarkable skill of invention:
- When the need for profit becomes imperative, CHIROPRACTORS are forced to find ways of getting or achieving it.
- If CHIROPRACTORS really need to do something, they will think of a way of doing it.
- If a CHIROPRACTOR really needs money, he will advocate ‘maintenance care’.
AND THAT’S WHAT IS CALLED ‘CHIROPRACTIC PROGRESS’!
Would you believe it? This is the 500th post on this blog!
When I started this blog less than three years ago, I would have never thought that I would have fun doing this; and I would not have expected to get hooked on it. In fact, it needed even a bit of arm twisting to try it, and I have to thank Alan for doing it and everything else. Without him, this blog would surely not exist.
With my very first post, I promised that my blog is not going to provide just another critique of alternative medicine; it is going to be different, I hope. The reasons for this are fairly obvious: I have researched alternative medicine for two decades. My team and I have conducted about 40 clinical trials and published more than 100 systematic reviews of alternative medicine. We were by far the most productive research unit in this area. For 14 years, we hosted an annual international conference for researchers in this field. I know many of the leading investigators personally, and I understand their way of thinking. I have rehearsed every possible argument for or against alternative medicine dozens of times.
In a nutshell, I am not someone who judges alternative medicine from the outside; I come from within the field. Arguably, I am the only researcher in this area who is willing [or capable?] to state publicly what is wrong with alternative medicine. This is perhaps one of the advantages of being an emeritus professor!
I am not sure whether I lived up to this promise – but I did try. And one thing is for sure, it was an eventful exercise. The blog now has ~ 20 000 readers every week; we had something like 15 000 comments; and some posts were re-tweeted several hundred times.
This seems to indicate that there is a need for a forum of this nature. Alternative medicine continues to be popular but critical thinking is not something that this field is blessed with. On the contrary, the misinformation on this subject is simply monstrous and seems to be growing every day. Factual and reliable information is very hard to come by, and therefore I feel that I am doing an important educational job here.
It’s a job which I certainly could not do alone. I therefore like to take this occasion to thank everyone who made my blog what it is today. Alan has already been mentioned but the many commentators deserve a big THANKS too – regardless of whether I agree or disagree with you, your comments make it all worth my while.
On 26/5/2015, I received the email reproduced below. I thought it was interesting, looked up its author (“Shawn is a philosopher and writer educated at York University in Toronto, and the author of two books. He’s also worked with Aboriginal youth in the Northwest Territories of Canada”) and decided to respond by writing a blog-post rather than by answering Alli directly.
Hello Dr. Ernst, this is Shawn Alli from Canada, a blogger and philosopher. I recently finished a critical article on James Randi’s legacy. It gets into everything from ideological science, manipulation, ESP, faith healing, acupuncture and homeopathy.
Let me know what you think about it:
It’s quite long so save it for a rainy day.
So far, the reply from skeptical organizations range from: “I couldn’t read further than the first few paragraphs because I disagree with the claims…” to one word replies: “Petty.”
It’s always nice to know how open-minded skeptical organizations are.
Hopefully you can add a bit more.
Yes, indeed, I can but try to add a bit more!
However, Alli’s actual article is far too long to analyse it here in full. I therefore selected just the bit that I feel most competent commenting on and which is closest to my heart. Below, I re-produce this section of Alli’s article in full. I add my comments at the end (in bold) by inserting numbered responses which refer to the numbers (in round brackets [the square ones refer to Alli’s references]) inserted throughout Alli’s text. Here we go:
Homeopathy & Acupuncture:
A significant part of Randi’s legacy is his war against homeopathy. This is where Randi shines even above mainstream scientists such as Dawkins or Tyson.
Most of his talks ridicule homeopathy as nonsense that doesn’t deserve the distinction of being called a treatment. This is due to the fact that the current scientific method is unable to account for the results of homeopathy (1). In reality, the current scientific method can’t account for the placebo effect as well (2).
But then again, that presents an internal problem as well. The homeopathic community is divided by those who believe it’s a placebo effect and those that believe it’s more than that, advocating the theory of water memory, which mainstream scientists ridicule and vilify (3).
I don’t know what camp is correct (4), but I do know that the homeopathic community shouldn’t follow the lead of mainstream scientists and downplay the placebo effect as, it’s just a placebo (5).
Remember, the placebo effect is downplayed because the current scientific method is unable to account for the phenomenon (3, 5). It’s a wondrous and real effect, regardless of the ridicule and vilification (6) that’s attached to it.
While homeopathy isn’t suitable as a treatment for severe or acute medical conditions, it’s an acceptable treatment for minor, moderate or chronic ones (7). Personally, I’ve never tried homeopathic treatments. But I would never tell individuals not to consider it. To each their own, as long as it’s within universal ethics (8).
A homeopathic community in Greece attempts to conduct an experiment demonstrating a biological effect using homeopathic medicine and win Randi’s million dollar challenge. George Vithoulkas and his team spend years creating the protocol of the study, only to be told by Randi to redo it from scratch.  (9) I recommend readers take a look at:
Randi’s war against homeopathy is an ideological one (10). He’ll never change his mind despite positive results in and out of the lab (11). This is the epitome of dogmatic ideological thinking (12).
The same is true for acupuncture (13). In his NECSS 2012 talk Randi says:
Harvard Medical School is now offering an advanced course for physicians in acupuncture, which has been tested endlessly for centuries and it does not work in any way. And believe me, I know what I’m talking about. 
Acupuncture is somewhat of a grey area for mainstream scientists and the current scientific method. One ideological theory states that acupuncture operates on principles of non-physical energy in the human body and relieving pressure on specific meridians. The current scientific method is unable to account for non-physical human energy and meridians.
A mainstream scientific theory of acupuncture is one of neurophysiology, whereby acupuncture works by affecting the release of neurotransmitters. I don’t know which theory is correct; but I do know that those who do try acupuncture usually feel better (14).
In regards to the peer-reviewed literature, I believe (15) that there’s a publication bias against acupuncture being seen as a viable treatment for minor, moderate or chronic conditions. A few peer-reviewed articles support the use of acupuncture for various conditions:
Eight sessions of weekly group acupuncture compared with group oral care education provide significantly better relief of symptoms in patients suffering from chronic radiation-induced xerostomia. 
It is concluded that this study showed highly positive effects on pain and function through the collaborative treatment of acupuncture and motion style in aLBP [acute lower back pain] patients. 
Given the limited efficacy of antidepressant treatment…the present study provides evidence in supporting the viewpoint that acupuncture is an effective and safe alternative treatment for depressive disorders, and could be considered an alternative option especially for patients with MDD [major depressive disorder] and PSD [post-stroke depression], although evidence for its effects in augmenting antidepressant agents remains controversial. 
In conclusion: We find that acupuncture significantly relieves hot flashes and sleep disturbances in women treated for breast cancer. The effect was seen in the therapy period and at least 12 weeks after acupuncture treatment ceased. The effect was not correlated with increased levels of plasma estradiol. The current study showed no side effects of acupuncture. These results indicate that acupuncture can be used as an effective treatment of menopausal discomfort. 
In conclusion, the present study demonstrates, in rats, that EA [electroacupuncture] significantly attenuates bone cancer induced hyperalgesia, which, at least in part, is mediated by EA suppression of IL-1…expression. 
In animal model of focal cerebral ischemia, BBA [Baihui (GV20)-based Scalp acupuncture] could improve IV [infarct volume] and NFS [neurological function score]. Although some factors such as study quality and possible publication bias may undermine the validity of positive findings, BBA may have potential neuroprotective role in experimental stroke. 
In conclusion, this randomized sham-controlled study suggests that electroacupuncture at acupoints including Zusanli, Sanyinjiao, Hegu, and Zhigou is more effective than no acupuncture and sham acupuncture in stimulating early return of bowel function and reducing postoperative analgesic requirements after laparoscopic colorectal surgery. Electroacupuncture is also more effective than no acupuncture in reducing the duration of hospital stay. 
In conclusion, we found acupuncture to be superior to both no acupuncture control and sham acupuncture for the treatment of chronic pain…Our results from individual patient data meta-analyses of nearly 18000 randomized patients in high-quality RCTs [randomized controlled trials] provide the most robust evidence to date that acupuncture is a reasonable referral option for patients with chronic pain. 
While Randi and many other mainstream scientists will argue (16) that the above claims are the result of ideological science and cherry picking, in reality, they’re the result of good science going up against dogmatic (17) and profit-driven (17) ideological (17) science.
Yes, the alternative medicine industry is now a billion dollar industry. But the global pharmaceutical medical industry is worth hundreds of trillions of dollars. And without its patients (who need to be in a constant state of ill health), it can’t survive (18).
Individuals who have minor, moderate, or chronic medical conditions don’t want to be part of the hostile debate between alternative medicine vs. pharmaceutical medical science (19). They just want to get better and move on with their life. The constant war that mainstream scientists wage against alternative medicine is only hurting the people they’re supposed to be helping (20).
Yes, the ideologies (21) are incompatible. Yes, there are no accepted scientific theories for such treatments. Yes, it defies what mainstream scientists currently “know” about the human body (22).
It would be impressive if a peace treaty can exist between both sides, where both don’t agree, but respect each other enough to put aside their pride and help patients to regain their health (23).
END OF ALLI’S TEXT
And here are my numbered comments:
(1) This is not how I understand Randi’s position. Randi makes a powerful point about the fact that the assumptions of homeopathy are not plausible, which is entirely correct – so much so that even some leading homeopaths admit that this is true.
(2) This is definitely not correct; the placebo effect has been studied in much detail, and we can certainly ‘account’ for it.
(3) In my 40 years of researching homeopathy and talking to homeopaths, I have not met any homeopaths who “believe it’s a placebo effect”.
(4) There is no ‘placebo camp’ amongst homeopaths; so this is not a basis for an argument; it’s a fallacy.
(5) They very definitely are mainstream scientists, like F Benedetti, who research the placebo effect and they certainly do not ‘downplay’ it. (What many people fail to understand is that, in placebo-controlled trials, one aims at controlling the placebo effect; to a research-naïve person, this may indeed LOOK LIKE downplaying it. But this impression is wrong and reflects merely a lack of understanding.)
(6) No serious scientist attaches ‘ridicule and vilification’ to it.
(7) Who says so? I know only homeopaths who hold this opinion; and it is not evidence-based.
(8) Ethics demand that patients require the best available treatment; homeopathy does not fall into this category.
(9) At one stage (more than 10 years ago), I was involved in the design of this test. My recollection of it is not in line with the report that is linked here.
(10) So far, we have seen no evidence for this statement.
(11) Which ones? No examples are provided.
(12) Yet another statement without evidence – potentially libellous.
(13) Conclusion before any evidence; sign for a closed mind?
(14) This outcome could be entirely unrelated to acupuncture, as anyone who has a minimum of health care knowledge should know.
(15) We are not concerned with beliefs, we concerned with facts here, aren’t we ?
(16) But did they argue this? Where is the evidence to support this statement?
(17) Non-evidence-based accusations.
(18) Classic fallacy.
(19) The debate is not between alt med and ‘pharmaceutical science’, it is between those who insist on treatments which demonstrably generate more good than harm, and those who want alt med regardless of any such considerations.
(20) Warning consumers of treatments which fail to fulfil the above criterion is, in my view, an ethical duty which can save much money and many lives.
(21) Yes, alt med is clearly ideology-driven; by contrast conventional medicine is not (if it were, Alli would have explained what ideology it is precisely). Conventional medicine changes all the time, sometimes even faster than we can cope with, and is mainly orientated on evidence which is not an ideology. Alt med hardly changes or progresses at all; for the most part, its ideology is that of a cult celebrating anti-science and obsolete traditions.
(22) Overt contradiction to what Alli just stated about acupuncture.
(23) To me, this seems rather nonsensical and a hindrance to progress.
In summary, I feel that Alli argues his corner very poorly. He makes statements without supporting evidence, issues lots of opinion without providing the facts (occasionally even hiding them), falls victim of logical fallacies, and demonstrates an embarrassing lack of knowledge and common sense. Most crucially, the text seems bar of any critical analysis; to me, it seems like a bonanza of unreason.
To save Alli the embarrassment of arguing that I am biased or don’t know what I am talking about, I’d like to declare the following: I am not paid by ‘Big Pharma’ or anyone else, I am not aware of having any other conflicts of interest, I have probably published more research on alt med (some of it with positive conclusions !!!) than anyone else on the planet, my research was funded mostly by organisations/donors who were in favour of alt med, and I have no reason whatsoever to defend Randi (I only met him personally once). My main motivation for responding to Alli’s invitation to comment on his bizarre article is that I have fun exposing ‘alt med nonsense’ and believe it is a task worth doing.
Many experts have argued that the growing popularity of alternative medicine (AM) mandates their implementation into formal undergraduate medical education. Most medical students seem to feel a need to learn about AM. Yet little is known about the student-specific need for AM education. The objective of this paper was address this issue, specifically the authors wanted to assess the self-reported need for AM education among Australian medical students.
Thirty second-year to final-year medical students participated in semi-structured interviews. A constructivist grounded theory methodological approach was used to generate, construct and analyse the data.
The results show that these medical students generally held favourable attitudes toward AM but had knowledge deficits and did not feel adept at counselling patients about AMs. All students were supportive of integrating AM into education, noting its importance in relation to the doctor-patient encounter, specifically with regard to interactions with medical management. Students recognised the need to be able to effectively communicate about AMs and advise patients regarding safe and effective AM use.
The authors of this survey concluded that Australian medical students expressed interest in, and the need for, AM education in medical education regardless of their opinion of it, and were supportive of evidence-based AMs being part of their armamentarium. However, current levels of AM education in medical schools do not adequately enable this. This level of receptivity suggests the need for AM education with firm recommendations and competencies to assist AM education development required. Identifying this need may help medical educators to respond more effectively.
One might object to such wide-reaching conclusions based on a sample size of just 30. However, there are several similar surveys from other parts of the world which seem to paint a similar picture: most medical students clearly do want to learn about AM. But this issue raises several important questions:
- How can this be squeezed into the already over-full curriculum?
- Should students learn about AM or should they learn how to practice AM?
- Who should teach this subject?
In my view, students should learn the essentials about AM but not how to do this or that therapy. Most deans of medical schools seem to agree with me on that particular point.
The question as to who should teach students about AM is, however, much more contentious. Most conventional medical instructors have no interest in and/or no knowledge of the subject. Consequently, there is a tendency for medical schools to delegate AM by hiring a few alternative practitioners to cover AM. Thus we see homeopaths teaching medical students all (well, almost all) about homeopathy, acupuncturists teaching acupuncture, herbalists teaching herbal medicine etc. To many observers, this might sound right and reasonable – but I beg to differ resolutely.
Most alternative practitioners who I have met (and these were many over the last 20 years) are clearly not capable of teaching their own subject in a way that befits a medical school. They have little or no idea about the nature of scientific evidence and usually lack the slightest hint of critical analysis. Thus a homeopaths might teach homeopathy such that students get the impression that it is well grounded in evidence, for instance. Students who have been taught in this fashion are not likely to advise their future patients responsibly on the subject in question: THE TEACHING OF NONSENSE IS BOUND TO RESULT IN NONSENSICAL PRACTICE!
In my view, AM is an ideal subject to acquaint medical students with the concepts of critical thinking. In this respect, it offers an almost opportunity for medical schools to develop much-needed skills in their students. Sadly, however, this is not what is currently happening. All too often, medical school deans find themselves caught between the devil and the deep blue sea. In the end, they tend to delegate the subject of AM to people who are not competent and should not be let loose on impressionable students.
I fear that progress and care of future patients are bound to suffer.
The task of UK Clinical Commissioning Groups (CCGs) is to ensure NHS funds are spent as effectively and responsibly as possible. This is particularly important in the current financial climate, as NHS budgets are under enormous pressure. For that reason, The Good Thinking Society (GTS, a pro-science charity) invited Liverpool CCG to reconsider whether the money (~ £ 30,000 pa) they spend on homeopathy represents good service to the public. Recently the CCG agreed to make a fresh decision on this contentious issue.
The GTS would prefer to see limited NHS resources spent on evidence-based medicine rather than on continued funding of homeopathy which, as readers of this blog will know, has repeatedly failed to demonstrate that it is doing more good than harm. It is encouraging to see Liverpool CCG take a first step in the right direction by agreeing to properly consider the best evidence and expertise on this issue.
Supporters of homeopathy frequently cite the concept of patient choice and claim that, if patients want homeopathy, they should have it free on the NHS. The principle is obviously important, but it is crucial that this choice is an informed one. The best evidence has conclusively shown that homeopathy is not an effective treatment, and to continue to offer ineffective treatments under the guise of patient choice raises troubling questions about the important concept of informed choice, and indeed of informed consent as well as medical ethics.
The GTS were represented by Salima Budhani and Jamie Potter of Bindmans LLP. Salima said: “This case underlines the necessity of transparent and accountable decision making by the controllers of health budgets, particularly in the light of the current financial climate in the NHS. CCGs have legal obligations to properly consider relevant evidence, as well as the views of experts and residents, in deciding how precious NHS resources are to be spent. It is essential that commissioning decisions are rational and evidence-based. Liverpool CCG’s decision to reconsider its position on the funding of homeopathy in these circumstances is to be welcomed.
“Our client has also called upon the Secretary of State for Health to issue guidance on the funding of homeopathy on the NHS. Public statements by the Secretary of State indicate that he does not support ongoing funding, yet he has so far declined to ask NICE to do any work on this issue. The provision of such guidance would be of significant benefit to CCGs in justifying decisions to terminate funding.”
Commenting on their decision, a Liverpool CCG spokesperson said: “Liverpool CCG currently resources a small homeopathy contract to the value of £30,000 per year that benefits a small number of patients in the city who choose to access NHS homeopathy care and treatment services. The CCG has agreed with the Good Thinking Society to carry out further engagement with patients and the general public to inform our future commissioning intentions for this service.”
Over the last two decades, prescriptions fulfilled in community pharmacies for homeopathy on the NHS in England have fallen by over 94% and homeopathic hospitals have seen their funding reallocated. This reduction indicates that the majority of doctors and commissioning bodies have acted responsibly by terminating funding for homeopathic treatments.

Twenty years ago, I published a short article in the British Journal of Rheumatology. Its title was ALTERNATIVE MEDICINE, THE BABY AND THE BATH WATER. Reading it again today – especially in the light of the recent debate (with over 700 comments) on acupuncture – indicates to me that very little has since changed in the discussions about alternative medicine (AM). Does that mean we are going around in circles? Here is the (slightly abbreviated) article from 1995 for you to judge for yourself:
“Proponents of alternative medicine (AM) criticize the attempt of conducting RCTs because they view this is in analogy to ‘throwing out the baby with the bath water’. The argument usually goes as follows: the growing popularity of AM shows that individuals like it and, in some way, they benefit through using it. Therefore it is best to let them have it regardless of its objective effectiveness. Attempts to prove or disprove effectiveness may even be counterproductive. Should RCTs prove that a given intervention is not superior to a placebo, one might stop using it. This, in turn, would be to the disadvantage of the patient who, previous to rigorous research, has unquestionably been helped by the very remedy. Similar criticism merely states that AM is ‘so different, so subjective, so sensitive that it cannot be investigated in the same way as mainstream medicine’. Others see reasons to change the scientific (‘reductionist’) research paradigm into a broad ‘philosophical’ approach. Yet others reject the RCTs because they think that ‘this method assumes that every person has the same problems and there are similar causative factors’.
The example of acupuncture as a (popular) treatment for osteoarthritis, demonstrates the validity of such arguments and counter-arguments. A search of the world literature identified only two RCTs on the subject. When acupuncture was tested against no treatment, the experimental group of osteoarthritis sufferers reported a 23% decrease of pain, while the controls suffered a 12% increase. On the basis of this result, it might seem highly unethical to withhold acupuncture from pain-stricken patients—’if a patient feels better for whatever reason and there are no toxic side effects, then the patient should have the right to get help’.
But what about the placebo effect? It is notoriously difficult to find a placebo indistinguishable to acupuncture which would allow patient-blinded studies. Needling non-acupuncture points may be as close as one can get to an acceptable placebo. When patients with osteoarthritis were randomized into receiving either ‘real acupuncture or this type of sham acupuncture both sub-groups showed the same pain relief.
These findings (similar results have been published for other AMs) are compatible only with two explanations. Firstly acupuncture might be a powerful placebo. If this were true, we need to establish how safe acupuncture is (clearly it is not without potential harm); if the risk/benefit ratio is favourable and no specific, effective form of therapy exists one might still consider employing this form as a ‘placebo therapy’ for easing the pain of osteoarthritis sufferers. One would also feel motivated to research this powerful placebo and identify its characteristics or modalities with the aim of using the knowledge thus generated to help future patients.
Secondly, it could be the needling, regardless of acupuncture points and philosophy, that decreases pain. If this were true, we could henceforward use needling for pain relief—no special training in or equipment for acupuncture would be required, and costs would therefore be markedly reduced. In addition, this knowledge would lead us to further our understanding of basic mechanisms of pain reduction which, one day, might evolve into more effective analgesia. In any case the published research data, confusing as they often are, do not call for a change of paradigm; they only require more RCTs to solve the unanswered problems.
Conducting rigorous research is therefore by no means likely to ‘throw out the baby with the bath water’. The concept that such research could harm the patient is wrong and anti-scientific. To follow its implications would mean neglecting the ‘baby in the bath water’ until it suffers serious damage. To conduct proper research means attending the ‘baby’ and making sure that it is safe and well.
My memoir ‘A SCIENTIST IN WONDERLAND’ has already brought many surprises (and about 20 most flattering reviews). A few days ago, the German version was published entitled ‘NAZIS, NADELN UND INTRIGEN’ (people who have not read it might find this title puzzling). The German publisher reported that the first print-run was sold out in the first 4 days.
In order to tempt you to read my memoir, I publish here the final section of the book which affirms that the link between my rather diverse experiences boils down to ethics.
…the most important link between my research into alternative medicine and that related to the Third Reich was that of medical ethics.
It should be axiomatic that ethics is indispensable to the practice of medicine, and is not something that can just be switched off at will. No branch of health care, including alter-native medicine, can be considered exempt from it. But the subject of ethics is seldom even considered in alternative medicine; many alternative practitioners have never been taught medical ethics, and where training in this area does exist, it tends to be at best superficial. There are thousands of books on alternative medicine but hardly more than a handful cover the subject of medical ethics in any depth. It is perhaps not surprising, therefore, that the principles of medical ethics are routinely ignored and frequently violated by promoters of alternative medicine.
Medical ethics seem to me to be violated, for example: when homeopaths prescribe or recommend homeopathic vaccinations for which there is not a shred of evidence; when chiropractors or other alternative practitioners happily promote bogus treatments for children with asthma or other serious conditions; when practitioners fail to obtain informed consent before commencing their treatments; when Prince Charles sells his “detox tincture” which is unable to eliminate poisons from your body, merely cash from your purse; when quacks inveigle desperate cancer patients by pretending they have found a cure; when pharmacists sell Bach Flower Remedies or other glorified placebos; when applied kinesiologists, iridologists, etc. claim that their baseless diagnostic tests are able to identify serious diseases; when pseudoscientists claim that certain alternative therapies are evidence-based because they managed to generate a false positive result purely by cherry-picking or massaging their data; when politicians who lack even the most basic understanding of science publicly support quackery, proclaiming that it is evidence-based.
And so on, and so on.
Some might criticize me here for claiming the moral high ground. But if I do so, it is for a good reason. Medical consultations are intrinsically unequal, with the clinician occupying a position of considerable power over often highly vulnerable patients. This places an important ethical onus on the caregiver to assist patients in making informed choices—an imperative and a trust that is breached each and every time that unproven nostrums born of ideology and wishful thinking are offered to people with assertions that they are an effective, valid approach to the treatment of disease.
When science is abused, hijacked or distorted in order to serve political or ideological belief systems, ethical standards will inevitably slip. The resulting pseudoscience is a deceit perpetrated on the weak and the vulnerable. We owe it to ourselves, and to those who come after us, to stand up for the truth, no matter how much trouble this might bring.
Today, I look back at the often stormy past from the peaceful vantage point of my retirement with a mixture of satisfaction and incredulity. The doctor and scientist may still be full of questions, but the musician in me breathes a sigh of relief that the performance, with all its impossible demands and fiendishly difficult passages, is finally over.
The FDA just made the following significant announcement:
The Food and Drug Administration (FDA) is announcing a public hearing to obtain information and comments from stakeholders about the current use of human drug and biological products labeled as homeopathic, as well as the Agency’s regulatory framework for such products. These products include prescription drugs and biological products labeled as homeopathic and over-the-counter (OTC) drugs labeled as homeopathic. FDA is seeking participants for the public hearing and written comments from all interested parties, including, but not limited to, consumers, patients, caregivers, health care professionals, patient groups, and industry. FDA is seeking input on a number of specific questions, but is interested in any other pertinent information participants would like to share.

The agenda will be posted soon
And this is what Reuters reported about the planned event:
The hearing, scheduled for April 20-21, will discuss prescription drugs, biological products, and over-the-counter drugs labeled homeopathic, a market that has expanded to become a multimillion dollar industry in the United States. The agency is set to evaluate its regulatory framework for homeopathic products after a quarter century. (http://1.usa.gov/1Hxwup3) An Australian government study released this month concluded that homeopathy does not work. (http://bit.ly/1BheAmR) The FDA issued a warning earlier this month asking consumers not to rely on asthma products labeled homeopathic that are sold over the counter. (http://1.usa.gov/1EEuKrC) Homeopathic medicines include pellets placed under the tongue, tablets, liquids, ointments, sprays and creams. The basic principles of homeopathy, formulated by German physician Samuel Hahnemann in the late 18th century, are based on a theory that a disease can be treated using small doses of natural substances that in a healthy person would produce symptoms of the disease. The agenda for the hearing will be posted soon, the FDA said on Tuesday.
In my view, this is an important occasion for experts believing in evidence to make their position regarding homeopathy heard. I therefore encourage all my readers who have an evidence-based opinion on homeopathy to submit it to the hearing.
How often have we heard it on this blog and elsewhere?
- chiropractic is progressing,
- chiropractors are no longer adhering to their obsolete concepts and bizarre beliefs,
- chiropractic is fast becoming evidence-based,
- subluxation is a thing of the past.
American chiropractors wanted to find out to what extent these assumptions are true and collected data from chiropractic students enrolled in colleges throughout North America. The stated purpose of their study is to investigate North American chiropractic students’ opinions concerning professional identity, role and future.
A 23-item cross-sectional electronic questionnaire was developed. A total of 7,455 chiropractic students from 12 North American English-speaking chiropractic colleges were invited to complete the survey. Survey items encompassed demographics, evidence-based practice, chiropractic identity and setting, and scope of practice. Data were collected and descriptive statistical analyses were performed.
A total of 1,243 questionnaires were electronically submitted. This means the response rate was 16.7%. Most respondents agreed (34.8%) or strongly agreed (52.2%) that it is important for chiropractors to be educated in evidence-based practice. A majority agreed (35.6%) or strongly agreed (25.8%) the emphasis of chiropractic intervention is to eliminate vertebral subluxations/vertebral subluxation complexes. A large number of respondents (55.2%) were not in favor of expanding the scope of the chiropractic profession to include prescribing medications with appropriate advanced training. Most respondents estimated that chiropractors should be considered mainstream health care practitioners (69.1%). About half of all respondents (46.8%) felt that chiropractic research should focus on the physiological mechanisms of chiropractic adjustments.
The authors of this paper concluded that the chiropractic students in this study showed a preference for participating in mainstream health care, report an exposure to evidence-based practice, and desire to hold to traditional chiropractic theories and practices. The majority of students would like to see an emphasis on correction of vertebral subluxation, while a larger percent found it is important to learn about evidence-based practice. These two key points may seem contradictory, suggesting cognitive dissonance. Or perhaps some students want to hold on to traditional theory (e.g., subluxation-centered practice) while recognizing the need for further research to fully explore these theories. Further research on this topic is needed.
What should we make of these findings? The answer clearly must be NOT A LOT.
- the response rate was dismal,
- the questionnaire was not validated
- there seems to be little critical evaluation or discussion of the findings.
If anything, these findings seem to suggest that chiropractors want to join evidence based medicine, but on their own terms and without giving up their bogus beliefs, concept and practices. They seem to want the cake and eat it, in other words. The almost inevitable result of such a development would be that real medicine becomes diluted with quackery.
