The UK petition to ban homeopathy for animals has so far achieved well over 3 000 signatures. Remarkably, it also prompted a reaction from the Faculty of Homeopathy which I reproduce here in full:
Homeopathy has a long history of being used successfully in veterinary practice for both domestic and farm animals. The EU recommends its use in its regulations on organic farms and is funding research into veterinary homeopathy as a way of reducing antibiotic use in livestock. It is nonsense to suggest that responsible pet owners and farmers are unable to distinguish between effective and ineffective medicines; they continue to use homeopathy because they see its benefits.
Membership of the Faculty of Homeopathy (VetMFHom) is bestowed on qualified veterinary surgeons who have completed a minimum of three years study of homeopathy and after a rigorous examination procedure. It differentiates the qualified veterinary homeopath from an unlicensed healer.
In a statement, the Royal College of Veterinary Surgeons said “… homeopathy is currently accepted by society and recognised by UK medicines legislation, and does not, in itself, cause harm to animals”. Before going on to say it could see no justification for banning veterinary surgeons from practising homeopathy.
In an age when antibiotic resistance is such an important issue, veterinary surgeons and farmers who have found they can limit the use of these drugs by using homeopathy should be applauded and not attacked.

Veterinary Dean, Faculty of Homeopathy
Such sentiments resonate with those of the UK’s most influential supporter of homeopathy, Prince Charles. Speaking at a global leaders summit on antimicrobial resistance, Prince Charles recently warned that Britain faced a “potentially disastrous scenario” because of the “overuse and abuse” of antibiotics. The Prince explained that he had switched to organic farming on his estates because of the growing threat from antibiotic resistance and now treats his cattle with homeopathic remedies rather than conventional medication. “As some of you may be aware, this issue has been a long-standing and acute concern to me,” he told delegates from 20 countries at The Royal Society in London. “I have enormous sympathy for those engaged in the vital task of ensuring that, as the world population continues to increase unsustainably and travel becomes easier, antibiotics retain their availability to overcome disease… It must be incredibly frustrating to witness the fact that antibiotics have too often simply acted as a substitute for basic hygiene, or as it would seem, a way of placating a patient who has a viral infection or who actually needs little more than patience to allow a minor bacterial infection to resolve itself.”
It seems that both Prince Charles and Peter Gregory believe that homeopathy can be employed to reduce the use of antibiotics in animals. So, let’s analyse this hypothesis a little closer.
The way I see it, the belief must be based on one of two assumptions:
- Homeopathic remedies are effective in treating or preventing bacterial infections.
- If farmers administer homeopathic remedies to their life-stock, they are less likely to administer unnecessary antibiotics.
Assumption No 1 can be rejected without much further debate; there is no evidence whatsoever that homeopathic remedies have antibiotic efficacy. In fact, the consensus today is that highly diluted homeopathic remedies are pure placebos.
Assumption No 2, however, might be more plausible and therefore deserves further scrutiny. If we do not tell the farmers nor the vets that homeopathic remedies are placebos, if, in other words, we mislead them to think they are efficacious medicines, they might give them to their animals instead of antibiotics. Consequently, the usage of antibiotics in animals would decrease. This strategy sounds plausible but, on second thought, it has many serious drawbacks:
- The truth has a high value in itself which we would disregard at our peril.
- One might not be able to keep the truth from the farmers and even less able to hide it from vets.
- If we mislead farmers and vets, we must also mislead the rest of the population; this means lots of people might start using homeopathic placebos even for serious conditions.
- Misleading farmers, vets and the rest of the population is clearly unethical.
- Misleading farmers and vets in this way might not be necessary; if there is abuse of antibiotics in farming, we ought to tackle this phenomenon directly.
- Misleading farmers and vets might be dangerous for at least two reasons: firstly, animals who truly need antibiotics would not receive adequate treatment; secondly, farmers and vets might eventually become convinced that homeopathy is efficacious and would therefore use it in all sorts of situations, even for serious diseases of humans.
Whichever way I twist and turn the assumption No 2, I fail to arrive at anything remotely sensible. But this leaves me with a huge problem: I would have to conclude that both the Veterinary Dean, Faculty of Homeopathy and the heir to the throne are bonkers… and, surely, this cannot be right either!!!
It would be easy to continue this series on ‘tricks of the trade’ for quite a while. But this might get boring, and I have therefore decided to call it a day. So here is the last instalment (feel free to post further tricks that you may know of [in the comments section below]):
CRITICS DON’T UNDERSTAND
It is almost inevitable that, sooner or later, someone will object to some aspect of alternative medicine. In all likelihood, his or her arguments are rational and based on evidence. If that happens, the practitioner has several options to save his bacon (and income). One of the easiest and most popular is to claim that “of course, you cannot agree with me because you do not understand!”
The practitioner now needs to explain that, in order to achieve the level of expertise he has acquired, one has to do much more than to rationalise or know about science. In fact, one has to understand the subject on a much deeper level. One has to immerse oneself into it, open one’s mind completely and become a different human being altogether. This cannot be achieved by scientific study alone; it requires years of meditative work. And not everyone has the ability to go down this difficult path. It takes a lot of energy, insight and vision to become a true healer. A true Deepak Chopra is not born but trained through hard work, dedication and concentration.
Critics who disagree are really to be pitied. They fail to exist on quite the same level as those who ‘are in the know’. Therefore one must not get annoyed with those who disagree, they cannot understand because they have not seen the light.
My advice is to start thinking critically and read up about the NO TRUE SCOTSMAN FALLACY; this will quickly enable you to look beyond the charisma of these gurus and expose their charlatanry to the full.
RESEARCH IS BEING SUPRESSED
Some critics stubbornly insist on evidence for the therapeutic claims made by quacks. That attitude can be awkward for the alternative practitioner – because usually there is no good evidence.
Cornered in this way, quacks often come up with a simple but effective conspiracy theory: the research has been done and it has produced fabulous results, but it has been supressed by… well, by whoever comes to mind. Usually BIG PHARMA or ‘the scientific establishment’ have to be dragged out into the frame again.
According to this theory, the pharmaceutical industry (or whoever comes in handy) was so shaken by the findings of the research that they decided to make it disappear. They had no choice, really; the alternative therapy in question was so very effective that it would have put BIG PHARMA straight out of business for ever. As we all know BIG PHARMA to be evil to the core, they had no ethical or moral qualms about committing such a crime to humanity. Profits must come before charity!
My advice is to explain to such charlatans that such conspiracy theories do, in fact, merely prove is that the quack’s treatment is not effective against their prosecution complex.
CRITICS ARE BOUGHT AND CORRUPT
If critics of alternative medicine become threatening to the quackery trade, an easy and much-used method is to discredit them by spreading lies about them. If the above-mentioned ploy “they cannot understand” fails to silence the nasty critics, the next step must be to claim they are corrupt. Why else would they spend their time exposing quackery?
Many people – alternative practitioners included – can only think of financial motivations; the possibility that someone might do a job for altruistic reasons does not occur to them. Therefore, it sounds most plausible that the critics of alternative medicine are doing it for money – after all, the quacks also quack for money.
My advice to potential users of alternative medicine who are confused by such allegations: do your own research and find out for yourself who is bought by whom and who has a financial interest in quackery selling well.
EVEN NOBEL PRIZE WINNERS AGREE WITH US
It is true, there are some Nobel Prize winners who defend homeopathy or other bogus treatments. Whenever this happens, the apologists of alternative medicine have a field day. They then cite the Nobel laureate ad nauseam and imply that his or her views prove their quackery to be correct.
Little do they know that they are merely milking yet another classical fallacy and that such regrettable events merely demonstrate that even bright people can make mistakes.
My advice is to check what the Nobel laureate actually said – more often than not, it turns out that a much-publicised quote is, in fact, a misquote – and what his or her qualifications are for making such a statement; a Nobel Prize in literature, for instance, is not a sufficient qualification for commenting on healthcare issues.
AS I ALRADY SAID: IF YOU KNOW OF MORE ‘TRICKS OF THE QUACKARY TRADE’, PLEASE POST THEM BELOW.
Homeopathy must be effective! It is used extensively throughout the world, not least India! If it were ineffective, as all these nasty sceptics insist, Indians would not use it in such large numbers.
How often have we heard this argument?
Take, for instance, statements from the ‘peer-reviewed’ literature such as this one: “At present, in India, homeopathy is the third most popular method of medical treatment after allopathy and Ayurveda. There are over 200,000 registered homeopathic doctors currently, with approximately 12,000 more being added every year.” Or take statements from UK homeopaths like this one: “It seems clear that homeopathy is there to stay in India. So next time you see or read some condescending and patronising rubbish about homeopathy in the media, know that in India, a country with a population of 1.2 billion people (that’s more than 20x the population of the UK) homeopathy is an integral part of the healthcare system and deeply respected by the people of that country.”
Yes, homeopaths have always loved to mislead the public with fallacies!
The appeal to popularity is, of course, a classic fallacy – but, in the case of homeopathy’s popularity in India, it is not just that; here is an intriguing aspect to the use of homeopathy in that country that shines a different light on the whole story.
Epidemiologists from Canada conducted semi-structured interviews of 175 Mumbai slum-based practitioners holding degrees in Ayurveda, homeopathy and Unani. Most providers gave multiple interviews. The researchers also observed 10 providers in clinical interactions, documenting clinical examinations, symptoms, history taking, prescriptions and diagnostic tests.
No practitioners exclusively used his or her system of training. The practice of biomedicine was frequent, with practitioners often using biomedical disease categories and diagnostics. The use of homeopathy was rare; only 4% of consultations with homeopaths resulted in the prescription of homeopathic remedies.
The authors concluded that important sources of health care in Mumbai’s slums, AYUSH physicians frequently use biomedical therapies and most refer patients with TB to chest physicians or the public sector. They are integral to TB care and control.
These data seem to suggest that the use of homeopathic remedies in India is far, far less than often claimed by apologists. Indian homeopaths seem to have much more sense than to use homeopathy for serious conditions. This is good news for Indian public health, in my view.
The story also shows how the ‘appeal to popularity’ is being misused for the promotion of homeopathy: not only is it based on poor logic but often also on false information.
The ACUPUNCTURE NOW FOUNDATION (ANF) have recently published a document that is worth drawing your attention to. But first I should perhaps explain who the ANF are. They state that “The Acupuncture Now Foundation (ANF) was founded in 2014 by a diverse group of people from around the world who were concerned about common misunderstandings regarding acupuncture and wanted to help acupuncture reach its full potential. Our goal is to become recognized as a leader in the collection and dissemination of unbiased and authoritative information about all aspects of the practice of acupuncture.”
This, I have to admit, sounds like music to my ears! So, I studied the document in some detail – and the music quickly turned into musac.
The document which they call a ‘white paper’ promises ‘a review of the research’. Reading even just the very first sentence, my initial enthusiasm turned into bewilderment: “It is now widely accepted across health care disciplines throughout the world that acupuncture can be effective in treating such painful conditions as migraine headaches, and low back, neck and knee pain, as well as a range of painful musculoskeletal conditions.” Any review of research that starts with such a deeply uncritical and overtly promotional statement, must be peculiar (quite apart from the fact that the ANF do not seem to appreciate that back and neck pain are musculoskeletal by nature).
As I read on, my amazement grew into bewilderment. Allow me to present a few further statements from this review (together with a link to the article provided by the ANF in support and a very brief comment by myself) which I found more than a little over-optimistic, far-fetched or plainly wrong:
“Male fertility, especially sperm production and motility, has also been shown to improve with acupuncture. In a recent animal study, electro-acupuncture was found to enhance germ cell proliferation. This action is believed to facilitate the recovery of sperm production (spermatogenesis) and may restore normal semen parameters in subfertile patients.”
The article supplied as evidence for this statement refers to an animal experiment using a model where sperm are exposed to heat. This has almost no bearing on the clinical situation in humans and does not lend itself to any clinical conclusions regarding the treatment of sub-fertile men.
“In a recent meta-analysis, researchers concluded that the efficacy of acupuncture as a stand-alone therapy was comparable to antidepressants in improving clinical response and alleviating symptom severity of major depressive disorder (MDD). Also, acupuncture was superior to antidepressants and waitlist controls in improving both response and symptom severity of post-traumatic stress disorder (PTSD). The incidence of adverse events with acupuncture was significantly lower than antidepressants.”
The review provided as evidence is wide open to bias; it was criticised thus: “the authors’ findings did not reflect the evidence presented and limitations in study numbers, sample sizes and study pooling, particularly in some subgroup analyses, suggested that the conclusions are not reliable”. Moreover, we need to know that by no means all reviews of the subject confirm this positive conclusion, for instance, this, this, or this one; all of the latter reviews are more up-to-date than the one provided by ANF. Crucially, a Cochrane review concluded that “the evidence is inconclusive to allow us to make any recommendations for depression-specific acupuncture”.
“A randomized controlled trial of acupuncture and counseling for patients presenting with depression, after having consulted their general practitioner in primary care, showed that both interventions were associated with significantly reduced depression at three months when compared to usual care alone.”
We have discussed the trial in question on this blog. It follows the infamous ‘A+B versus B’ design which cannot possibly produce a negative result.
Now, please re-read the first paragraph of this post; but be careful not to fall off your chair laughing.
There would be more (much more) to criticise in the ANF report but, I think, these examples are ENOUGH!
Let me finish by quoting from the ANF’s view on the future as cited in their new ‘white paper’: “Looking ahead, it is clear that acupuncture is poised to make significant inroads into conventional medicine. It has the potential to become a part of every hospital’s standard of care and, in fact, this is already starting to take place not only in the U.S., but internationally. The treatment is a cost-effective and safe method of relieving pain in emergency rooms, during in-patient stays and after surgery. It can lessen post-operative nausea, constipation and urinary difficulties, and have a positive impact on conditions like hypertension, anxiety and insomnia…
Driven by popular demand and a growing body of scientific evidence, acupuncture is beginning to be taken seriously by mainstream conventional medicine, which is incorporating it into holistic health programs for the good of patients and the future of health care. In order for this transition to take place most effectively, misunderstandings about acupuncture need to be addressed. We hope this white paper has helped to clarify some of those misunderstandings and encourage anyone with questions to contact the Acupuncture Now Foundation.”
My question is short and simple: IGNORANCE OR FRAUD?
Yes, yes, yes, I know: we have too few women in our ‘ALT MED HALL OF FAME’. This is not because I have anything against them (quite the contrary) but, in alternative medicine research, the boys by far outnumber the girls, I am afraid.
You do remember, of course, you has previously been admitted to this austere club of excellence; only two women so far. Here is the current list of members to remind you:
David Peters (osteopathy, homeopathy, UK)
Nicola Robinson (TCM, UK)
Peter Fisher (homeopathy, UK)
Simon Mills (herbal medicine, UK)
Gustav Dobos (various, Germany)
Claudia Witt (homeopathy, Germany and Switzerland)
George Lewith (acupuncture, UK)
John Licciardone (osteopathy, US)
If you study the list carefully, you will also notice that, until now, I have totally ignored the chiropractic profession. This is a truly embarrassing omission! When it comes to excellence in research, who could possibly bypass our friends, the chiropractors?
Today we are going to correct these mistakes. Specifically, we are going to increase the number of women by 50% (adding one more to the previous two) and, at the same time, admit a deserving chiropractor to the ALT MED HALL OF FAME.
Cheryl Hawk is currently the Executive Director of Northwest Center for Lifestyle and Functional Medicine, University of Western States, Portland, USA. Previously she worked as Director of Clinical Research at the Logan University College of Chiropractic, Chesterfield, USA, and prior to that she was employed at various other institutions. Since many years she has been a shining light of chiropractic research. She is certainly not ‘small fry’ when it comes to the promotion of chiropractic.
Cheryl seems to prefer surveys as a research tool over clinical trials, and it was therefore not always easy to identify those of her 67 Medline-listed articles that reported some kind of evaluation of the value of chiropractic. Here are, as always, the 10 most recent papers where I could extract something like a data-based conclusion (in bold) from the abstract.

American chiropractors appear similar to chiropractors in other countries, and other health professionals regarding their favorable attitudes towards EBP, while expressing barriers related to EBP skills such as research relevance and lack of time. This suggests that the design of future EBP educational interventions should capitalize on the growing body of EBP implementation research developing in other health disciplines. This will likely include broadening the approach beyond a sole focus on EBP education, and taking a multilevel approach that also targets professional, organizational and health policy domains.

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.

These results strongly suggest that chiropractic clinical researchers are not developing ICDs at a readability level congruent with the national average acceptable level. The low number of elements in some of the informed consent documents raises concern that not all research participants were fully informed when given the informed consent, and it may suggest that some documents may not be in compliance with federal requirements. Risk varies among institutions and even within institutions for the same intervention.

Given the utilization of chiropractic services by the older adult, it is imperative that providers be familiar with the evidence for and the prudent use of different management strategies for older adults.
I am pleased to say that Prof Hawk gave me no problems at all; her case is clear: she is a champion of using research as a means for promoting chiropractic, has published many papers in this vein, clearly prefers the journals of chiropractic that nobody other than chiropractors ever access, and has an impeccable track record when it comes to avoiding negative conclusions which could harm chiropractic in any way.
Very well done indeed!
WELCOME, PROF HAWK, TO THE ‘ALT MED HALL OF FAME’.
The queue outside my ‘ALT MED HALL OF FAME’ was getting restless because I did not admit any new members for some time. So, I better get cracking!
You remember, of course, who has been honoured so far; the list of members (main research interest, country) is as follows:
Nicola Robinson (TCM, UK)
Peter Fisher (homeopathy, UK)
Simon Mills (herbal medicine, UK)
Gustav Dobos (various, Germany)
Claudia Witt (homeopathy, Germany and Switzerland)
George Lewith (acupuncture, UK)

Today, we are going to have a look at Prof David Peters. This is what our friends from the ‘COLLEGE OF MEDICINE’ say about him:
“David Peters MB, ChB, DRCOG, DMSMed MFHom FLCOM trained as a GP, a musculoskeletal physician and also as a homeopathic and osteopathic practitioner. For fifteen years he directed the complementary therapies development programme at Marylebone Health Centre. Professor Peters is one of the founding faculty of the University of Westminster’s School of Life Sciences, where he is Clinical Director. Professor Peters is a member of the Council and former chair of the British Holistic Medical Association and Editor of its Journal of Holistic Healthcare. He has co-authored or edited six books about integrated healthcare. His research interests include the role of non-pharmaceutical treatments in mainstream medicine, wellbeing in long-term conditions and the development of integrated practitioners.”
I did my usual Medline search but found only 16 Medline-listed articles authored by David Peters. This is amazing because he has been involved in UK alt med much longer than I have. Even more amazing is that none of these papers seem to refer to clinical trials. Perhaps he is not convinced of this type of research?
In order to evaluate his output, I took the sentence that came nearest to a conclusion from the most recent 10 articles. Below you find first the titles of each paper (with the link to it), second the list of its authors and third the sentence that formulated a conclusion (in bold).

This paper describes the current status and evidence base for acupuncture, homeopathy, herbal and manipulative medicine, as well as the regulatory framework within which these therapies are provided. It also explores the present role of the Royal College of Physicians’ Subcommittee on Complementary and Alternative Medicine (CAM) in relation to these developments. A number of CAM professions have encouraged the Royal College of Physicians Subcommittee to act as a reference point for their discussions with the conventional medical profession and the subcomittee believes that they are able to fulfil this function.

It is possible to introduce rigour and reflectiveness when providing a homeopathic service in general practice by assessing the needs of patient and practitioners, agreeing intake guidelines, developing referral processes, implementing audit cycles. Clear lines of communication can be established and a patient-centred outcome measure can be introduced into the treatment cycle.
I could not find any further articles that I could classify as providing data; so I stopped well short of the envisaged 10 papers. I have to admit, I was hesitant: does David deserve to be in the ALT MED HALL OF FAME? In the end, I gave him the benefit of the doubt. Why? Mainly because I am impressed with his scope of practice. Here is what he himself wrote about this aspect:
“I use a range of approaches: osteopathy and medical acupuncture, as well as nutrition and mind-body medicine – meditation, relaxation techniques, breath-work, self-hypnosis, biofeedback, and simple yoga-based exercises. Sometimes herbal medicines, complex homeopathy, nutritional supplements, trigger-point or joint injections can be a valuable too. Somatic Experiencing is a gentle form of body-centred psychotherapy for problems that have come on after traumatic incidents. When I want to assess the impact of stress on the body I use a painless approach involving computer-based heart rate variability testing and breath analysis; sometimes salivary cortisol profiling too. Where required I can prescribe conventional medicine and were they are needed I might suggest scans, X-rays or blood tests.”
Peter is perhaps not the most industrious researcher when it comes to publishing papers, but he fulfils the criterion of not ever publishing anything negative that might rock the boat or distract from the true value of alternative medicine.
LONG LIVE THE POSITIVE RESULT!
Seasonal allergic rhinitis (hay fever) is a common condition which can considerably reduce the quality of life of sufferers. Homeopathy is often advocated – but does it work?
A new study was meant to be an “assessment of the clinical effectiveness of homeopathic remedies in the alleviation of hay fever symptoms in a typical clinical setting.”
The investigator performed a ‘clinical observational study’ of eight patients from his private practice using Measure Yourself Medical Outcome Profile (MYMOP) self-evaluation questionnaires at baseline and again after two weeks and 4 weeks of individualized homeopathic treatment which was given as an add-on to conventional treatments.
The average MYMOP scores for the eyes, nose, activity and wellbeing had improved significantly after two and 4 weeks of homeopathic treatment. The overall average MYMOP profile score at baseline was 3.83 (standard deviation, SD, 0.78). After 14 and 28 days of treatment the average score had fallen to 1.14 (SD, 0.36; P<0.001) and 1.06 (SD, 0.25; P<0.001) respectively.
The author concluded as follows: Individualized homeopathic treatment was associated with significant alleviation of hay fever symptoms, enabling the reduction in use of conventional treatment. The results presented in this study can be considered as a step towards a pilot pragmatic study that would use more robust outcome measures and include a larger number of patients prescribed a single or a multiple homeopathic prescription on an individualized basis.
It is hard to name the things that are most offensively wrong here; the choice is too large. Let me just list three points:
- The study design is not matched to the research question.
- The implication that homeopathy had anything to do with the observed outcome is unwarranted.
- The conclusion that the results might lend themselves to develop a pilot study is meaningless.
The question whether homeopathy is an effective therapy for hay fever has been tested before, even in RCTs. It seems therefore mysterious why one needs to revert to tiny observational studies in order to plan a pilot, and even less for an assessment of effectiveness.
There are few conditions which are more time-dependent than hay fever. Any attempt of testing the effectiveness of medical interventions without a control group seems therefore not just questionable but wasteful. Clinical studies absorb resources; even if the author was happy to waste his time, he should not assume that he can freely waste the time, effort and availability of his patients.
Two final points, if I may:
- An observational study of homeopathy for hay-fever without a control group might be utterly useless but it is still an investigation that requires certain things. As far as I can see, this study did not even have ethics approval nor is there a mention of informed consent. Strictly speaking, this makes it an unethical study.
- If we allow research of this nature to take place and be published, we give clinical research a bad name and undermine the confidence of the public in science.
I am puzzled how such a paper could pass peer review and how an Elsevier journal could even consider publishing it.
I am editor in chief of a journal called FACT. It has a large editorial board, and I am always on the look-out for people who might be a good, productive and colourful addition to it. On 3 June, I sent an invitation to Mel Koppelman, who is by now well known to regular readers of this blog. Here is a copy:
can I ask you a question?
would you consider joining the ed-board of FACT [as you mentioned it in one of your comments, I assume you know this journal – but you are wrong in implying that it has anything to do with the pharmaceutical or any other industry]? if you agree, we would expect you to write 2-3 ‘summaries/commentaries’ per year. in return you get a free subscription and, of course, can submit other articles.
no, this is not a joke or a set-up. I like to have the full spectrum of opinion/expertise on my ed-board, and I do think you understand science quite well. our opinions differ but that’s what I think is good for the journal.
think about it – please.
On 6 June, she replied as follows:
Great to hear from you, I hope you enjoyed your weekend.
Thank you very much for the kind offer, it’s something I would consider. I certainly have no problem with, and in fact embrace, people who have different opinions and views from my own, so long as I feel that they have integrity in their approach.
Just a few questions / comments:
1) Regarding FACT’s affiliations, what I said in my comment was that it was a publication of the Royal Pharmaceutical Society. According to Wiley’s website, Focus on Alternative and Complementary Medicine is copyright by Royal Pharmaceutical Society. It’s also listed on the Pharmaceutical Press website.
Are you telling me that’s incorrect? That I’m “wrong” in saying there’s a relationship? I obviously need to understand the nature of the publication whose editorial board I’m considering joining. Very confusing that you as editor say there’s no relationship to the RPS and yet they claim copyright over your publication. Incidentally, is FACT self-sufficient, earning all of its income from subscriptions? Or does any financial support come from the publishers?
2) As enticing as a free subscription to FACT is, I have access to more high quality peer-reviewed reading material than I could enjoy in many lifetimes. Because my skills seem to be in high demand and because I already spend 10-20 hours per week doing unpaid volunteer work, any additional projects that I take on at this time would need to be financially compensated. I understand that this may be a deal-breaker.
3) While I have no issue with you having different views when it comes to medical research, in order to choose to work with your publication, it’s important to me that it’s run by people with a high level of academic integrity and put patient welfare at the forefront of it’s agenda.
In March, you came out in public support of the NICE draft guidelines. You were quoted in the Guardian as saying: “It is good to see that Nice have now caught up with the evidence. Neither spinal manipulation nor acupuncture are supported by good science when it comes to treating low back pain.”
Following this, it was brought to your attention that the recommendations were contrary to best evidence and that the conclusions were unsupportable. While you have the option of following this up to make sure that the record reflects best evidence, you have indicated that you have no interest in evaluating the situation and possibly admitting an error. This behaviour is concerning from the perspective of academic integrity, particularly when it directly leads to increased human suffering (policy in several countries has already been changed based on the draft), and I would be worried that by joining your board I could be associated with such unethical behaviour.
Perhaps if I understood better your position, which seems to be to ignore the situation, not follow up on the concerns raised, and leave your comments uncorrected even though they may be inaccurate and backing guidelines that cause harm to patients, that might allay certain reservations.
Anyways, these are my initial thoughts. I hope you have an opportunity to enjoy the beautiful weather, and I look forward to hearing from you.
At that stage, I began to fear that I had made a mistake. But, giving her the benefit of the doubt, I swallowed my pride and replied as politely as I could to her concerns which, in my view, were odd, to say the least. This is what I wrote on 7 June:
Thank you for your reply to my invitation. Let me address your points in turn:
- I said that FACT has nothing to do with the pharma industry which is true [when you state that “you as editor say there’s no relationship to the RPS” – it suggests to me that you did not read my email properly]. In their own words, the RPS is “the professional membership body for pharmacists and pharmacy in Great Britain and an internationally renowned publisher of medicines information.” [http://www.rpharms.com/home/about-us.asp] They have a similar status as the Royal Colleges. In the 2 decades that I am running the journal, there has been not a single instance of interference of any kind. We use them simply as an excellent publishing house. And yes, FACT is to the best of my knowledge self-sufficient and survives without funds from 3rd parties.
- I am delighted to hear that your skills are in demand.
- I have stated my position regarding the draft NICE guideline ad nauseam: I prefer to wait until I see their next version of the draft before I make further comments on it. In my view, this is both reasonable and honourable. If you disagree, I can do little about it other than expressing my sincere regrets.
I hope these brief clarifications are helpful for you to arrive at a decision.
On 8 June, I received Mel’s reply:
How interesting! Is he trying to ‘keep his enemies closer’ or am I being too skeptical? He has recognised your talents and dedication and intellect so he is not altogether stupid after all! I eagerly await his response to your reply.
Those who have studied with Ernst say that he’s a genuine chap and misunderstood – which I know is almost unimaginable given his behaviour – but we always have to allow for the possibility that we have misjudged people however remote! Also, people can turn – especially when they get older and near retirement. Alternatively he may just fancy you!…
Mel Koppelman Really enjoying hearing y’all’s thoughts on this. I just want to say that If I had thought that the chances of me being able to create positive change by joining FACT were high, I would have tempered the tone of my reply. But the simple fact that EE can’t even be factual or forthright about whose journal it is suggests an irreparable break with reality. And surely there’s an issue (academic? ethical? legal?) with recruiting someone to your board and denying an industry tie when there is one? Not to mention that if the RSP does fund his journal, he’s been lying about his conflicts of interest. Is that someone I want to spend time adding value to that could be spent with family, patients, time in nature or really making positive change by supporting the ANF? I’ll be interested to read his reply if there is one and especially how he responds regarding the relationship between FACT and RSP. Will keep y’all posted.
John McDonald Healthy skepticism! Healthy journal! And it’s 99% fact-free!
I hope that you find these exchanges as amusing as I did – but are they important? Perhaps not exactly, but revealing certainly. They shed some light on the mind-set of acupuncturists and perhaps other alternative practitioners as well. Let me try to explain.
What struck me first was the degree of suspicion, even outright hostility from the acupuncturists. I had made it quite clear that I was asking Mel to join my Editorial-Board because of her views which vastly differ from mine. In science, differences of opinions and backgrounds can be stimulating and often generate progress. That is not something that seems to be wanted by alternative practitioners; they do not seem to tolerate criticism, different perspectives or views. One cannot help asking to what degree this attitude is immature or even dogmatic.
The next thing that baffled me was the speed with which conclusions are jumped upon. Everyone seemed to be instantly convinced that I was via my journal FACT in the pocket of the pharmaceutical industry. Nobody even bothered to look up what the Royal Pharmaceutical Society truly stand for and to verify that they do NOT represent ‘BIG PHARMA’. This blindness to the possibility of being wrong confirms my fear that alternative therapists are guided by strong beliefs which must not be questioned and are hard to influence, even with facts that take less than a minute to research.
And then there are, of course, the personal attacks which came quick, thick and fast. Its authors might think that such attacks get under my skin. If so, they are mistaken: if anything, they amuse me! I have long been of the opinion that they are important victories of reason. When an acupuncturist went as far as diagnosing me as being borderline psychopathic, I almost fell off my chair laughing! To me, this remark (which has emerged several times before) is emblematic, as it suggests several things at once:
- The author is obviously rude
- He/she is incompetent, even stupid
- He/she lacks empathy – after all, one would expect from a healthcare professional to show some understanding, if I were truly ill! And if not, one would expect more respect towards mentally ill patients.
- But, of course, he/she did not mean it like that; he/she merely meant to insult me. And employing mental health issues for this purpose shows a remarkable lack of professionalism, in my view.
Am I making too much of all this? Perhaps – sorry, I am almost done.
But first I need to briefly address Mel’s doubts about my integrity. She can, of course, question what she likes as often as she wants. My point is that repeating nonsensical arguments ad nauseam does not render then sensical.
Finally, there is Mel’s public claim that I have been lying about my conflict of interests. To me, it suggests a degree of desperation, perhaps even fanaticism, that is only surpassed by her inability to apologize after the truth had become undeniable even to her.
I know that there are some people who would have sued for libel.
For that I find all this far too hilarious.
We tend to trust charities; many of us donate to charities; we think highly of the work they do and the advice they issue. And why shouldn’t we? After all, a ‘charity’ is ‘an institution or organization set up to provide help, money, etc, to those in need’. Not a hint at anything remotely sinister here – charities are good!
Except, of course, those that are not so good!
By ‘not so good’ I mean charities that misinform the public to a point where they might even endanger our health, well-being and savings. Yes, I am speaking of those charities that promote unproven or disproven alternative therapies – and unfortunately, there are many of those around today.
Our recent letter in the SUNDAY TIMES, tried to alert the public to this problem and to the fact that the UK regulator seems to be failing to do much about it. A Charity Commission spokesman, in turn, replied that his organisation had received the letter and would respond formally to it:
“The Commission is required to register organisations as charities which are established for exclusively charitable purposes for the public benefit,” he said. “Charitable purposes for the advancement of health include conventional methods as well as complementary, alternative or holistic methods which are concerned with healing mind, body and spirit in the alleviation of symptoms and the cure of illness. Those organisations dealing with complementary and alternative medicines must be able to demonstrate that they are capable of promoting health otherwise they will not be for the public benefit.
“The Commission is the registrar and regulator of charities however it is not the authority in the efficacy of any and every non-traditional medical treatment. These are issues of substantial debate with a variety of opinions. Each case is considered on its merits based on the evidence available. To be charitable there needs to be sufficient evidence of the efficacy of the method to be used. The Commission must further be assured that any potential harm that might be said to arise does not outweigh the benefit identified by the method.
“The Commission expects charities to provide information that is factually accurate with legitimate evidence.”
But is the information provided by all charities factually accurate?
Take, for instance, YES TO LIFE! Have a good look and then decide for yourself.
On their website they state: “We provide support, information and financial assistance to those with cancer seeking to pursue approaches that are currently unavailable on the NHS. We also run a series of educational seminars and workshops which are aimed at the general public who want to know more and practitioners working with people who have cancer.”
The website informs us about many alternative therapies and directly or indirectly promote them for the curative or supportive treatment of cancer. I have chosen 5 of them and copied the respective summaries as published by YES TO LIFE. My main selection criterion was having done some research myself on the modality in question. Here are the 5 cancer treatments which I selected; the text from YES TO LIFE is in bold, and that of my published research is in normal print with a link to the published paper:
Carctol is a relatively inexpensive product, specifically formulated to assist cells with damaged respiration, it is also a powerful antioxidant that targets free radicals, the cause of much cellular damage. It also acts to detoxify the system.
Often given intravenously as part of a programme of Metabolic Therapy, Laetrile is a non-toxic extract of apricot kernels. The claimed mechanism of action that is broken down by enzymes found in cancer cells. Hydrogen cyanide, one of the products of this reaction then has a local toxic effect on the cells.
The claims that laetrile or amygdalin have beneficial effects for cancer patients are not currently supported by sound clinical data. There is a considerable risk of serious adverse effects from cyanide poisoning after laetrile or amygdalin, especially after oral ingestion. The risk-benefit balance of laetrile or amygdalin as a treatment for cancer is therefore unambiguously negative.
Mistletoe therapy was developed as an adjunct to cancer treatment in Switzerland in 1917-20, in the collaboration between Dr I Wegman MD and Dr Rudolf Steiner PhD (1861-1925). Mistletoe extracts are typically administered by subcutaneous injection, often over many years. Mistletoe treatment improves quality of life, supports patients during recommended conventional cancer treatments and some studies show survival benefit. It is safe and has no adverse interactions with conventional cancer treatments.
None of the methodologically stronger trials exhibited efficacy in terms of quality of life, survival or other outcome measures. Rigorous trials of mistletoe extracts fail to demonstrate efficacy of this therapy.
A type of low toxicity chemotherapy derived from a combination of two known cytotoxic drugs that are of little use individually, as the doses required for effective anticancer action are too high to be tolerated. However the combination is effective at far lower doses, with few side effects.
The data from randomised clinical trials suggest Ukrain to have potential as an anticancer drug. However, numerous caveats prevent a positive conclusion, and independent rigorous studies are urgently needed. [To judge the validity of this last treatment, I also recommend reading a previous post of mine.]
Finally, it might be informative to see who the individuals behind YES TO LIFE are. I invite you to have a look at their list of medical advisors which, I think, speaks for itself. It includes, for instance, Dr Michael Dixon of whom we have heard before on this blog, for instance, here, here and here.
Say no more!
This post is dedicated to Mel Koppelman.
Those who followed the recent discussions about acupuncture on this blog will probably know her; she is an acupuncturist who (thinks she) knows a lot about research because she has several higher qualifications (but was unable to show us any research published by herself). Mel seems very quick in lecturing others about research methodology. Yesterday, she posted this comment in relation to my previous post on a study of aromatherapy and reflexology:
Professor Ernst, This post affirms yet again a rather poor understanding of clinical trial methodology. A pragmatic trial such as this one with a wait-list control makes no attempt to look for specific effects. You say “it is quite simply wrong to assume that this outcome is specifically related to the two treatments.” Where have specific effects been tested or assumed in this study? Your statement in no way, shape or form negates the author’s conclusions that “aromatherapy massage and reflexology are simple and effective non-pharmacologic nursing interventions.” Effectiveness is not a measure of specific effects.
I am most grateful for this comment because it highlights an issue that I had wanted to address for some time: The meanings of the two terms ‘efficacy and effectiveness’ and their differences as seen by scientists and by alternative practitioners/researchers.
Let’s start with the definitions.
I often use the excellent book of Alan Earl-Slater entitled THE HANDBOOK OF CLINICAL TRIALS AND OTHER RESEARCH. In it, EFFICACY is defined as ‘the degree to which an intervention does what it is intended to do under ideal conditions. EFFECTIVENESS is the degree to which a treatment works under real life conditions. An EFFECTIVENESS TRIAL is a trial that ‘is said to approximate reality (i. e. clinical practice). It is sometimes called a pragmatic trial’. An EFFICACY TRIAL ‘is a clinical trial that is said to take place under ideal conditions.’
In other words, an efficacy trial investigates the question, ‘can the therapy work?’, and an effectiveness trial asks, ‘does this therapy work?’ In both cases, the question relate to the therapy per se and not to the plethora of phenomena which are not directly related to it. It seems logical that, where possible, the first question would need to be addressed before the second – it does make little sense to test for effectiveness, if efficacy has not been ascertained, and effectiveness without efficacy does not seem to be possible.
In my 2007 book entitled UNDERSTANDING RESEARCH IN COMPLEMENTARY AND ALTERNATIVE MEDICINE (written especially for alternative therapists like Mel), I adopted these definitions and added: “It is conceivable that a given therapy works only under optimal conditions but not in everyday practice. For instance, in clinical practice patients may not comply with a therapy because it causes adverse effects.” I should have added perhaps that adverse effects are by no means the only reason for non-compliance, and that non-compliance is not the only reason why an efficacious treatment might not be effective.
Most scientists would agree with the above definitions. In fact, I am not aware of a debate about them in scientific circles. But they are not something alternative practitioners tend to like. Why? Because, using these strict definitions, many alternative therapies are neither of proven efficacy nor effectiveness.
What can be done about this unfortunate situation?
Simple! Let’s re-formulate the definitions of efficacy and effectiveness!
Efficacy, according to some alternative medicine proponents, refers to the therapeutic effects of the therapy per se, in other words, its specific effects. (That coincides almost with the scientific definition of this term – except, of course, it fails to tell us anything about the boundary conditions [optimal or real-life conditions].)
Effectiveness, according to the advocates of alternative therapies, refers to its specific effects plus its non-specific effects. Some researchers have even introduced the term ‘real-life effectiveness’ for this.
This is why, the authors of the study discussed in my previous post, could conclude that “aromatherapy massage and reflexology are simple… effective… interventions… to help manage pain and fatigue in patients with rheumatoid arthritis.” Based on their data, neither aromatherapy nor reflexology has been shown to be effective. They might appear to be effective because patients expected to get better, or patients in the no-treatment control group felt worse for not getting the extra care. Based on studies of this nature, giving patients £10 or a box of chocolate might also turn out to be “simple… effective… interventions… to help manage pain and fatigue in patients with rheumatoid arthritis.” Based on these definitions of efficacy and effectiveness, there are hardly any limits to bogus claims for any old quackery.
Such obfuscation suits proponents of alternative therapies fine because, using such definitions, virtually every treatment anyone might ever think of can be shown to be effective! Wishful thinking, it seems, can fulfil almost any dream, it can even turn the truth upside down.
Or can anyone name an alternative treatment that cannot even generate a placebo response when administered with empathy, sympathy and care? Compared to doing nothing, virtually every ineffective therapy might generate outcomes that make the treatment look effective. Even the anticipation of an effect alone might do the trick. How often have you had a tooth-ache, went to the dentist, and discovered sitting in the waiting room that the pain had gone? Does that mean that sitting in a waiting room is an effective treatment for dental pain?
In fact, some enthusiasts of alternative medicine could soon begin to argue that, with their new definition of ‘effectiveness’, we no longer need controlled clinical trials at all, if we want to demonstrate how effective alternative therapies truly are. We can just do observational studies without a control group, note that lots of patients get better, and ‘Bob is your uncle’!!! This is much faster, saves money, time and effort, and has the undeniable advantage of never generating a negative result.
To most outsiders, all this might seem a bit like splitting hair. However, I fear that it is far from that. In fact, it turns out to be a fairly fundamental issue in almost any discussion about the value or otherwise of alternative medicine. And, I think, it is also a matter of principle that reaches far beyond alternative medicine: if we allow various interest groups, lobbyists, sects, cults etc. to use their own definitions of fundamentally important terms, any dialogue, understanding or progress becomes almost impossible.
