Many experts have warned us that, when we opt for dietary supplements, we might get more than we bargained for. A recent article reminded us that the increased availability and use of botanical dietary supplements and herbal remedies among consumers has been accompanied by an increased frequency of adulteration of these products with synthetic pharmaceuticals. Unscrupulous producers may add drugs and analogues of various classes, such as phosphodiesterase type 5 (PDE-5) inhibitors, weight loss, hypoglycemic, antihypertensive and anti-inflammatory agents, or anabolic steroids, to develop or intensify biological effects of dietary supplements or herbal remedies. The presence of such adulterated products in the marketplace is a worldwide problem and their consumption poses health risks to consumers.

Other authors recently warned that these products are often ineffective, adulterated, mislabeled, or have unclear dosing recommendations, and consumers have suffered injury and death as a consequence. When Congress passed the Dietary Supplement Health and Education Act, it stripped the Food and Drug Administration of its premarket authority, rendering regulatory controls too weak to adequately protect consumers. State government intervention is thus warranted. This article reviews studies reporting on Americans’ use of dietary supplements marketed for weight loss or muscle building, notes the particular dangers these products pose to the youth, and suggests that states can build on their historical enactment of regulatory controls for products with potential health consequences to protect the public and especially young people from unsafe and mislabeled dietary supplements.

A new study has shown that these problems are not just theoretical but are real and common.

Twenty-four products suspected of containing anabolic steroids and sold in fitness equipment shops in the UK were analyzed for their qualitative and semi-quantitative content using full scan gas chromatography-mass spectrometry (GC-MS), accurate mass liquid chromatography-mass spectrometry (LC-MS), high pressure liquid chromatography with diode array detection (HPLC-DAD), UV-Vis, and nuclear magnetic resonance (NMR) spectroscopy. In addition, X-ray crystallography enabled the identification of one of the compounds, where reference standard was not available.

Of the 24 products tested, 23 contained steroids including known anabolic agents; 16 of these contained steroids that were different to those indicated on the packaging and one product contained no steroid at all. Overall, 13 different steroids were identified; 12 of these are controlled in the UK under the Misuse of Drugs Act 1971. Several of the products contained steroids that may be considered to have considerable pharmacological activity, based on their chemical structures and the amounts present.

The authors concluded that such adulteration could unwittingly expose users to a significant risk to their health, which is of particular concern for naïve users.

The Internet offers thousands of supplements for sale; specifically for bodybuilders there are hundreds of supplements all claiming things that are untrue or untested. The lax regulations that exist in this area seem to be often ignored completely. I think it is important to inform customers that most supplements are a waste of money and some even a waste of health.

In 2004, I published an article rather boldly entitled ‘Ear candles: a triumph of ignorance over science’. Here is its summary:

Ear candles are hollow tubes coated in wax which are inserted into patients’ ears and then lit at the far end. The procedure is used as a complementary therapy for a wide range of conditions. A critical assessment of the evidence shows that its mode of action is implausible and demonstrably wrong. There are no data to suggest that it is effective for any condition. Furthermore, ear candles have been associated with ear injuries. The inescapable conclusion is that ear candles do more harm than good. Their use should be discouraged.

Sadly, since the publication of this paper, ear candles have not become less but more popular. There are about 3 000 000 websites on the subject; most are trying to sell products and make claims which are almost comically misguided; three examples have to suffice:

I said ALMOST comical because such nonsense has, of course a downside. Not only are consumers separated from their cash for no benefit whatsoever, but they are also exposed to danger; again, three examples from the medical literature might explain:

  • Otolaryngologists from London described a case of ear candling presenting as hearing loss, and they concluded that this useless therapy can actually cause damage to the ears.
  • A 50-year-old woman presented to her GP following an episode of ear candling. After 15 minutes, the person performing the candling burned herself while attempting to remove the candle and spilled candle wax into the patient’s right ear canal. On examination, a piece of candle wax was found in the patient’s ear, and she was referred to the local ear, nose, and throat department. Under general aesthetic, a large mass of solidified yellow candle wax was removed from the deep meatus of the ear. The patient had a small perforation in her right tympanic membrane. Results of a pure tone audiogram showed a mild conductive hearing loss on the right side. At a follow-up appointment 1 month later, the perforation was still there, and the patient’s hearing had not improved.
  • case report of a 4-year-old girl from New Zealand was published. The patient was diagnosed to suffer from otitis media. During the course of the ear examination white deposits were noticed on her eardrum; this was confirmed as being caused by ear candling.

I should stress that we do not know how often such events happen; there is no monitoring system, and one might expect that the vast majority of cases do not get published. Most consumers who experience such problems, I would guess, are far to embarrassed to admit that they have been taken in by this sort of quackery.

It was true 10 yeas ago and it is true today: ear candles are a triumph of ignorance over science. But also they are a victory of gullibility over common sense and the unethical exploitation of naive hope by greedy frauds.

When someone has completed a scientific project, it is customary to publish it [‘unpublished science is no science’, someone once told me many years ago]. To do so, he needs to write it up and submit it to a scientific journal. The editor of this journal will then submit it to a process called ‘peer review’.

What does ‘peer review’ entail? Well, it means that 2-3 experts are asked to critically assess the paper in question, make suggestions as to how it can be improved and submit a recommendation as to whether or not the article deserves to be published.

Peer review has many pitfalls but, so far, nobody has come up with a solution that is convincingly better. Many scientists are under pressure to publish [‘publish or perish’], and therefore some people resort to cheating. A most spectacular case of fraudulent peer review has been reported recently in this press release:

SAGE statement on Journal of Vibration and Control

London, UK (08 July 2014) – SAGE announces the retraction of 60 articles implicated in a peer review and citation ring at the Journal of Vibration and Control (JVC). The full extent of the peer review ring has been uncovered following a 14 month SAGE-led investigation, and centres on the strongly suspected misconduct of Peter Chen, formerly of National Pingtung University of Education, Taiwan (NPUE) and possibly other authors at this institution.

In 2013 the then Editor-in-Chief of JVC, Professor Ali H. Nayfeh,and SAGE became aware of a potential peer review ring involving assumed and fabricated identities used to manipulate the online submission system SAGE Track powered by ScholarOne Manuscripts™. Immediate action was taken to prevent JVC from being exploited further, and a complex investigation throughout 2013 and 2014 was undertaken with the full cooperation of Professor Nayfeh and subsequently NPUE.

In total 60 articles have been retracted from JVC after evidence led to at least one author or reviewer being implicated in the peer review ring. Now that the investigation is complete, and the authors have been notified of the findings, we are in a position to make this statement.

While investigating the JVC papers submitted and reviewed by Peter Chen, it was discovered that the author had created various aliases on SAGE Track, providing different email addresses to set up more than one account. Consequently, SAGE scrutinised further the co-authors of and reviewers selected for Peter Chen’s papers, these names appeared to form part of a peer review ring. The investigation also revealed that on at least one occasion, the author Peter Chen reviewed his own paper under one of the aliases he had created.

Unbelievable? Perhaps, but sadly it is true; some scientists seem to be criminally ingenious when it comes to getting their dodgy articles into peer-reviewed journals.

And what does this have to do with ALTERNATIVE MEDICINE, you may well ask. The Journal of Vibration and Control is not even medical and certainly would never consider publishing articles on alternative medicine. Such papers go to one of the many [I estimate more that 1000] journals that cover either alternative medicine in general or any of the modalities that fall under this wide umbrella. Most of these journals, of course, pride themselves with being peer-reviewed – and, at least nominally, that is correct.

I have been on the editorial board of most of the more important journals in alternative medicine, and I cannot help thinking that their peer review process is not all that dissimilar from the fraudulent scheme set up by Peter Chen and disclosed above. What happens in alternative medicine is roughly as follows:

  • a researcher submits a paper for publication,
  • the editor sends it out for peer review,
  • the peer reviewers are either those suggested by the original author or members of the editorial board of the journal,
  • in either case, the reviewers are more than likely to be uncritical and recommend publication,
  • in the end, peer review turns out to be a farcical window dressing exercise with no consequence,
  • thus even very poor research and pseudo-research are being published abundantly.

The editorial boards of journals of alternative medicine tend to be devoid of experts who are critical about the subject at hand. If you think that I am exaggerating, have a look at the editorial board members of ‘HOMEOPATHY’ (or any other journal of alternative medicine) and tell me who might qualify as a critic of homeopathy. When the editor, Peter Fisher, recently fired me from his board because he felt I had tarnished the image of homeopathy, this panel lost the only person who understood the subject matter and, at the same time, was critical about it (the fact that the website still lists me as an editorial board member is merely a reflection of how slow things are in the world of homeopathy: Fisher fired me more than a year ago).

The point I am trying to make is simple: peer review is never a perfect method but when it is set up to be deliberately uncritical, it cannot possibly fulfil its function to prevent the publication of dodgy research. In this case, the quality of the science will be inadequate and generate false-positive messages that mislead the public.

‘THE HINKLEY TIMES’ is not a paper that I read often, I have to admit – but maybe I should! It was there that I found the following remarkable article:

Bosworth MP David Tredinnick has asked questions in the House of Commons about the growing problem of antibiotic resistance within hospitals, suggesting herbal remedies could be answer.

The Tory MP, who has a keen interest in alternative medicine particularly herbal curatives, asked Jeremy Hunt, Secretary of State for Health, whether the problem was being discussed at the very top level.

He said: “Does my right honourable friend agree that a critical problem that A and E units will face in the future is antibiotic resistance? Is he aware that the science and technology committee, of which I am a member, has been looking at this issue and it also interests the health committee, of which I am also a member? Can he assure me that he is talking to the Prime Minister about how to stimulate new antibiotic research, and will he also remember that nature has its own remedies, such as tea tree oil?”

In reply Mr Hunt said: “My honourable friend is right about the seriousness of the issue of antimicrobial resistance. Some 25,000 people die in Europe every year as a result of the failure of antibiotics – more than die in road traffic accidents. I raised the issue at the World Health Assembly and I have discussed it closely with the Prime Minister.”

David Tredinnick is no stranger to strange ideas. Wikipedia (yes I know, many people do not like it as a source) sums it up quite succinctly:

He is a supporter of complementary and alternative medicine (CAM). He has made supportive comments in Parliament on homeopathy, despite continued lack of evidence of its effectiveness. He has supported chiropractic and mentioned the influence of the Moon on blood clotting. In this same debate he characterised scientists as “racially prejudiced”. He has tabled several early day motions in support of homeopathy’s continued funding on the National Health Service.Tredinnick’s views continue to cause amused disbelief in some quarters and a spokesman for the Royal College of Surgeons of England said they would “laugh their heads off” at the suggestion they could not operate at the full moon.

At the 2010 general election, in addition to candidates from the two main parties, Tredinnick was opposed by New Scientist journalist Dr. Michael Brooks who objected to “Tredinnick’s outspoken promotion of complementary and alternative medicine.”During a hustings debate called by Brooks to “highlight the scientific literacy of the UK’s elected representatives” Brooks claimed that Tredinnick regarded homeopathy as a suitable treatment for Malaria and HIV, which Tredinnick did not deny. Tredinnick in turn argued that “alternative treatments are incredibly good value for money” and stated his belief that randomised controlled trials are not effective at evaluating very dilute preparations.

In March 2013 Tredinnick was ridiculed as “nonsensical” by the government’s outgoing chief scientist, Sir John Beddington, who said the MP had fallen for the “Galileo fallacy” (Galileo was laughed at but was right, therefore since I am laughed at I must be right).

In July 2013 Tredinnick sponsored an EDM congratulating a farmer on his decision to use homeopathy with what were claimed to be positive results.The motion was supported by one other MP but the British veterinary association says there is no evidence of any benefit.

Tredinnick is a supporter of astrology especially the use of it in medical practice.In November 2009, he spoke at a meeting organised by the Astrological Association of Great Britain, where he related his personal experience of astrology and illness, advocating that astrology be integrated into the NHS.

Tredinnick’s appointment to the Health committee in June 2010 was criticised in two science reports in the Guardian. Martin Robbins said his appointment was “an extremely disturbing development” even though “Tredinnick is a figure unlikely to be taken seriously by policymakers” whilst Nature‘s Adam Rutherford described Tredinnick as “misinformed about a great many things” and said that “giving [him] influence on medical policy a bad move.”The Telegraph writer Ian Douglas also described it as “a problem.”

His appointment to the Science and technology committee also drew criticism. Andy McSmith in the Independent, cited his views that homeopathy could cure HIV, TB, malaria, urinary infections, diarrhoea, skin eruptions, diabetes, epilepsy, eye infections, intestinal parasites, cancer, and gangrene amongst others and quoted Imran Khan, head of the Campaign for Science and Engineering, as saying that “someone with such incredibly odd views is not helpful”. Tom Whipple in the Times said his appointment caused despair,whilst Elizabeth Gibney in the Times Higher Education quoted the Skeptical Voter website as saying that Tredinnick is “perhaps the worst example of scientific illiteracy in government”…

In 2009 Tredinnick attempted to claim the £125 cost of attending a course on “intimate relationships” through his Parliamentary expenses. He was also found to have used expenses to purchase astrology software, claiming it was for a debate on alternative medicine.

Compared to some of theses bizarre activities, the notion that herbal remedies might provide the solution for antibiotic resistance seems almost reasonable and clever.


Tredinnick does not seem to know that:

  • many antibiotics originate from plants or other natural substances,
  • several large pharmaceutical companies are feverishly looking for more such substances from plants,
  • most plants do actually contain substances which have antibiotic activity,
  • however, most cannot be used as medicines, for instance, because they are far too toxic (tea tree oil is a good example for this),
  • once a pure compound has been isolated from a plant and is used therapeutically, it ceases to be herbal medicine (which is defined as the use of full plant extracts),
  • it is thus unlikely that full plant extracts, i. e. herbal medicine, will ever provide a solution to antibiotic resistance.

I have little doubt that Tredinnick will continue to mislead parliament and the public with his nonsensical views about alternative medicine. And even if it might have no effect whatsoever, I will continue to point out just how nonsensical they are.

Some time ago, I published a post entitled HOW TO BECOME A CHARLATAN. This prompted ‘THE NORWEGIAN ACADEMY OF SCIENCE AND LETTERS’ to invite me to give a lecture on the subject, a great honour, I am sure. Consequently, I have thought about this somewhat unusual subject quite a lot.

Obviously, my thoughts come from the perspective of someone who has researched alternative medicine for many years. Pseudoscientists seem to love alternative medicine and proponents of alternative medicine love pseudoscience. As a result, alternative medicine is densely populated by pseudoscientists.

But what is the characteristic of pseudoscience? Reflecting on this question, I found not one but several hallmarks (and for each of them, there are many posts on this blog which provide further explanations):

Based on these 12 hallmarks, one could create a simple score which indicates the likelihood of the presence of pseudoscience. In other words, it might be useful to consider pseudoscience in terms of a sliding scale. Some things in alternative medicine can be just a bit pseudoscientific, others quite a lot, while others again are hopelessly so.

The issue of pseudoscience is by no means just academic; it is very real problem and has many important, practical implications. The most important one probably is that, in health care (and other areas as well), pseudoscience can be harmful, even to the point that it costs lives of vulnerable patients who believe that everything masquerading as science can be relied upon.

I find it always nice to see that people appreciate my work. Yet sometimes I am a little surprised to realise what some commercially interested firms make of it. Recently I came across a website that proudly used my research for advertising the use of magnetic bracelets against pain. Here is the text in question:

The extra strong magnets make this magnetic bracelet the fastest acting pain reliever. While wearing this magnetic bracelet customers with wrist and hand pain report significant pain relief….

What is a magnetic bracelet and what are the benefits? Magnetic bracelets are a piece of jewelry, worn for the therapeutic benefits of the magnetic field. Magnetic bracelets has been used successfully by many people for pain relief of inflammatory conditions such as arthritis, tendinitis and bursitis.

A randomized, placebo controlled trial with three parallel groups, came to the conclusion : Pain from osteoarthritis of the hip and knee decreases when wearing magnetic bracelets. It is uncertain whether this response is due to specific or non-specific (placebo) effects. Tim Harlow, general practitioner, Colin Greaves, research fellow, Adrian White, senior research fellow, Liz Brown, research assistant, Anna Hart, statistician, Edzard Ernst, professor of complementary medicine.

The entrepreneurs seem to have forgotten a few things which we tried to make clear in our paper:

  • this article was published in the Christmas issue of the BMJ which specialises in publishing unusual and odd findings with a high entertainment value,
  • in our paper, we point out that “the contamination of group B with stronger magnets prevented a more objective estimation of any-placebo effect”,
  • and stressed that “there were problems with the weak magnets”,
  • and that “a per-specification analysis suggested (but could not confirm) a specific effect of magnetic bracelets over and above placebo”.

Most importantly, this was just one trial, and surely one swallow does not make a summer! We should always consider the totality of the reliable evidence. Being conscientious researchers, at the time, we did exactly that and conducted a systematic review. Here is the abstract in its full beauty:


Static magnets are marketed with claims of effectiveness for reducing pain, although evidence of scientific principles or biological mechanisms to support such claims is limited. We performed a systematic review and meta-analysis to assess the clinical evidence from randomized trials of static magnets for treating pain.


Systematic literature searches were conducted from inception to March 2007 for the following data sources: MEDLINE, EMBASE, AMED (Allied and Complementary Medicine Database), CINAHL, Scopus, the Cochrane Library and the UK National Research Register. All randomized clinical trials of static magnets for treating pain from any cause were considered. Trials were included only if they involved a placebo control or a weak magnet as the control, with pain as an outcome measure. The mean change in pain, as measured on a 100-mm visual analogue scale, was defined as the primary outcome and was used to assess the difference between static magnets and placebo.


Twenty-nine potentially relevant trials were identified. Nine randomized placebo-controlled trials assessing pain with a visual analogue scale were included in the main meta-analysis; analysis of these trials suggested no significant difference in pain reduction (weighted mean difference [on a 100-mm visual analogue scale] 2.1 mm, 95% confidence interval -1.8 to 5.9 mm, p = 0.29). This result was corroborated by sensitivity analyses excluding trials of acute effects and conditions other than musculoskeletal conditions. Analysis of trials that assessed pain with different scales suggested significant heterogeneity among the trials, which means that pooling these data is unreliable.


The evidence does not support the use of static magnets for pain relief, and therefore magnets cannot be recommended as an effective treatment. For osteoarthritis, the evidence is insufficient to exclude a clinically important benefit, which creates an opportunity for further investigation.

So, would I, on the basis of the current best evidence, recommend magnetic bracelets to people who suffer from pain? No! In my view, only charlatans would do such a thing.

When I first read about agrohomeopathy (i.e. the use of potentised preparations for the health of plants and soils) I thought that it must be a hoax. Then I realised that it was entirely serious (a Google search returns ~28 000 hits for ‘agrohomeopathy’) – serious but nevertheless too weird for words. Because it is so utterly unbelievable, I cite (in italics) the key parts of an article on the subject.

What’s better than ORGANIC or BIODYNAMIC farming? AGROHOMEOPATHY! What is Agrohomeopathy? It’s the specialized area of homeopathy used to treat your garden and crops. Agrohomeopathy is the most chemical free, non-toxic method of growing food and other crops that you can get. Agrohomeopathy makes your plants resistant to disease and pests by strengthening them from the inside out. In nature, it is the weakest of organisms that are attacked and destroyed. Agrohomeopathy helps build up the plant’s basic structure and gives it optimum health, thus reducing and sometimes even eliminating it’s susceptibility. And the skeptics can’t blame THESE effects on placebo, can they?!….

Homeopathic treatment for your crops is a win-win situation. It is backed by decades of research and practice. Try it for yourself and see. And if you have problems or need help, there are experts in the field who are eager to help, who want to get your feedback & experience…

If you think this is far-fetched, rest assured that other sources go even further. Look at this statement, for instance:

Agro-Homeopathy not only treats the disease symptoms of the plant and performs preventive actions, but can also treat traumas retained in the biological memory of the plant, which resulted from conditions such as forced hybridization, moving to places outside their natural habitats , or exaggerated fertilization that maximizes production to the extreme.

So, plants have a ‘biological memory’ that is able to retain information of a past trauma! Fascinating, this gets more fantastic by the minute.

And there is plenty of practical advice too; just consider this helpful hint, if you are a keen gardener: the effects and benefits of homeopathic Silicea are so numerous that an entire article has been devoted to them at: Homeopathic Silica – The Gardener’s Friend. Needless to say, Silicea is one remedy no gardener or farmer should be without…

According to this website, homeopathic silica is a miracle cure; it

  1. Aids germination of seeds
  2. Reduces transplant shock
  3. Strengthens weak and spindly plants
  4. Increases vigour and resistance of plants to pests, moulds, and mildew
  5. Aids water retention in plants growing on arid soils
  6. Stimulates flower growth, both in number and size
  7. Assists seed generation and development
  8. Improves fruit-setting when applied after flowering
  9. Stimulates premature flowering and prevents seed formation when applied in overdose to weeds
  10. Changes the ionisation of soil particles so that water-repellent soil readily absorbs moisture … and more!

The sceptics can indeed not blame ‘THESE effects’ on placebo. Nobody needs to do that because they do not exist! I could not find a single piece of reliable evidence to demonstrate that highly diluted homeopathic remedies can cure diseases of plants.

I hope that a few agrohomeopathic readers of these lines will correct me by showing me solid data – but somehow I doubt it.

A recent meta-analysis evaluated the efficacy of acupuncture for treatment of irritable bowel syndrome (IBS) and arrived at bizarrely positive conclusions.

The authors state that they searched 4 electronic databases for double-blind, placebo-controlled trials investigating the efficacy of acupuncture in the management of IBS. Studies were screened for inclusion based on randomization, controls, and measurable outcomes reported.

Six RCTs were included in the meta-analysis, and 5 articles were of high quality.  The pooled relative risk for clinical improvement with acupuncture was 1.75 (95%CI: 1.24-2.46, P = 0.001). Using two different statistical approaches, the authors confirmed the efficacy of acupuncture for treating IBS and concluded that acupuncture exhibits clinically and statistically significant control of IBS symptoms.

As IBS is a common and often difficult to treat condition, this would be great news! But is it true? We do not need to look far to find the embarrassing mistakes and – dare I say it? – lies on which this result was constructed.

The largest RCT included in this meta-analysis was neither placebo-controlled nor double blind; it was a pragmatic trial with the infamous ‘A+B versus B’ design. Here is the key part of its methods section: 116 patients were offered 10 weekly individualised acupuncture sessions plus usual care, 117 patients continued with usual care alone. Intriguingly, this was the ONLY one of the 6 RCTs with a significantly positive result!

The second largest study (as well as all the other trials) showed that acupuncture was no better than sham treatments. Here is the key quote from this trial: there was no statistically significant difference between acupuncture and sham acupuncture.

So, let me re-write the conclusions of this meta-analysis without spin, lies or hype: These results of this meta-analysis seem to indicate that:

  1. currently there are several RCTs testing whether acupuncture is an effective therapy for IBS,
  2. all the RCTs that adequately control for placebo-effects show no effectiveness of acupuncture,
  3. the only RCT that yields a positive result does not make any attempt to control for placebo-effects,
  4. this suggests that acupuncture is a placebo,
  5. it also demonstrates how misleading studies with the infamous ‘A+B versus B’ design can be,
  6. finally, this meta-analysis seems to be a prime example of scientific misconduct with the aim of creating a positive result out of data which are, in fact, negative.

There is much debate about the usefulness of chiropractic. Specifically, many people doubt that their chiropractic spinal manipulations generate more good than harm, particularly for conditions which are not related to the spine. But do chiropractors treat such conditions frequently and, if yes, what techniques do they employ?

This investigation was aimed at describing the clinical practices of chiropractors in Victoria, Australia. It was a cross-sectional survey of 180 chiropractors in active clinical practice in Victoria who had been randomly selected from the list of 1298 chiropractors registered on Chiropractors Registration Board of Victoria. Twenty-four chiropractors were ineligible, 72 agreed to participate, and 52 completed the study.

Each participating chiropractor documented encounters with up to 100 consecutive patients. For each chiropractor-patient encounter, information collected included patient health profile, patient reasons for encounter, problems and diagnoses, and chiropractic care.

Data were collected on 4464 chiropractor-patient encounters between 11 December 2010 and 28 September 2012. In most (71%) cases, patients were aged 25-64 years; 1% of encounters were with infants. Musculoskeletal reasons for the consultation were described by patients at a rate of 60 per 100 encounters, while maintenance and wellness or check-up reasons were described at a rate of 39 per 100 encounters. Back problems were managed at a rate of 62 per 100 encounters.

The most frequent care provided by the chiropractors was spinal manipulative therapy and massage. The table shows the precise conditions treated

Depression 29 (0.48%) 0.66 (0.10–4.23) 0.288

These findings are impressive in that they suggest that most Australian chiropractors treat non-spinal conditions for which there is no evidence that the most frequently used interventions are effective. The treatments employed are depicted in this graph:
Distribution of techniques and care provided by chiropractors, with 95% CI

Chiro system = chiropractic system of care, eg, Applied Kinesiology, Sacro-Occipital Technique, Neuroemotional Technique. Flexion distraction = chiropractic treatment table that flexes in the middle to provide traction and mobilisation to the lumbar spine.]

There is no good evidence I know of demonstrating these techniques to be effective for the majority of the conditions listed in the above table.

A similar bone of contention is the frequent use of ‘maintenance’ and ‘wellness’ care. The authors of the article comment: The common use of maintenance and wellness-related terms reflects current debate in the chiropractic profession. “Chiropractic wellness care” is considered by an indeterminate proportion of the profession as an integral part of chiropractic practice, with the belief that regular chiropractic care may have value in maintaining and promoting health, as well as preventing disease. The definition of wellness chiropractic care is controversial, with some chiropractors promoting only spine care as a form of wellness, and others promoting evidence-based health promotion, eg, smoking cessation and weight reduction, alongside spine care. A 2011 consensus process in the chiropractic profession in the United States emphasised that wellness practice must include health promotion and education, and active strategies to foster positive changes in health behaviours. My own systematic review of regular chiropractic care, however, shows that the claimed effects are totally unproven.

One does not need to be overly critical to conclude from all this that the chiropractors surveyed in this investigation earn their daily bread mostly by being economical with the truth regarding the lack of evidence for their actions.

When we talk about conflicts of interest, we usually think of financial concerns. But conflicts of interests also extend to non-financial matters, such as strong beliefs. These are important in alternative medicine – I would even go as far as to claim that they dominate this field.

My detractors have often claimed that this is where my problem lies. They are convinced that, in 1993, I came into the job as PROFESSOR OF COMPLEMENTARY MEDICINE with an axe to grind; I was determined or perhaps even paid to show that all alternative medicine is utter hocus-pocus, they say. The truth is that, if anything, I was on the side of alternative medicine – and I can prove it. Using the example of homeopathy, I have dedicated an entire article to demonstrate that the myth is untrue – I was not closed-minded or out to ditch homeopathy (or any other form of alternative medicine for that matter).

What then could constitute my ‘conflict of interest’? Surely, he was bribed, I hear them say. Just look at the funds he took from industry. Some of those people have even gone to the trouble of running freedom of information requests to obtain the precise figures for my research-funding. Subsequently they triumphantly publish them and say: Look he got £x from this company and £y from that firm. And they are, of course, correct: I did receive support from commercially interested parties on several occasions. But what my detractors forget is that these were all pro-alternative medicine institutions. More importantly, I always made very sure that no strings were attached with any funds we accepted.

Our core funds came from ‘The Laing Foundation’ which endowed Exeter University with £ 1.5 million. This was done with the understanding that Exeter would put the same amount again into the kitty (which they never did). Anyone who can do simple arithmetic can tell that, to sustain up to 20 staff for almost 20 years, £1.5 million is not nearly enough. There must have been other sources. Who exactly gave money?

Despite utterly useless fundraising by the University, we did manage to obtain additional funds. I managed to receive support in the form of multiple research fellowships, for instance. It came from various sources; for instance, manufacturers of herbal medicines, Boots, the Pilkington Family Trust (yes, the glass manufacturers).

A hugely helpful contributor to our work was the sizable number (I estimate around 30) of visitors from abroad who came on their own money simply because they wanted to learn from and with us. They stayed between 3 months and 4 years, and importantly contributed to our research, knowledge and fun.

In addition, we soon devised ways to generate our own money. For instance, we started an annual conference for researchers in our field which ran for 14 successful years. As we managed everything on a shoestring and did all the organisation ourselves, we made a tidy profit each year which, of course, went straight back into our research. We also published several books which generated some revenue for the same purpose.

And then we received research funding for specific projects, for instance, from THE PRINCE OF WALES’ FOUNDATION FOR INTEGRATED HEALTH, a Japanese organisation supporting Jorhei Healing, THE WELCOME TRUST, the NHS, and even a homeopathic company.

So, do I have a conflict of interest? Did I take money from anyone who might have wanted to ditch alternative medicine? I don’t think so! And if I tell you that, when I came to Exeter in 1993, I donated ~£120 000 of my own funds towards the research of my unit, even my detractors might, for once, be embarrassed to have thought otherwise.
