Have you ever wondered whether doctors who practice homeopathy are different from those who don’t.
Silly question, of course they are! But how do they differ?
Having practised homeopathy myself during my very early days as a physician, I have often thought about this issue. My personal (and not very flattering) impressions were noted in my memoir where I describe my experience working in a German homeopathic hospital:
… some of my colleagues used homeopathy and other alternative approaches because they could not quite cope with the often exceedingly high demands of conventional medicine. It is almost understandable that, if a physician was having trouble comprehending the multifactorial causes and mechanisms of disease and illness, or for one reason or another could not master the equally complex process of reaching a diagnosis or finding an effective therapy, it might be tempting instead to employ notions such as dowsing, homeopathy or acupuncture, whose theoretical basis, unsullied by the inconvenient absolutes of science, was immeasurably more easy to grasp.
Some of my colleagues in the homeopathic hospital were clearly not cut out to be “real” doctors. Even a very junior doctor like me could not help noticing this somewhat embarrassing fact…
But this is anecdote and not evidence!
So, where is the evidence?
It was published last week and made headlines in many UK daily papers.
Our study was aimed at finding out whether English GP practices that prescribe any homeopathic preparations might differ in their prescribing of other drugs. We identified practices that made any homeopathy prescriptions over six months of data. We measured associations with four prescribing and two practice quality indicators using multivariable logistic regression.
Only 8.5% of practices (644) prescribed homeopathy between December 2016 and May 2017. Practices in the worst-scoring quartile for a composite measure of prescribing quality were 2.1 times more likely to prescribe homeopathy than those in the best category. Aggregate savings from the subset of these measures where a cost saving could be calculated were also strongly associated. Of practices spending the most on medicines identified as ‘low value’ by NHS England, 12.8% prescribed homeopathy, compared to 3.9% for lowest spenders. Of practices in the worst category for aggregated price-per-unit cost savings, 12.7% prescribed homeopathy, compared to 3.5% in the best category. Practice quality outcomes framework scores and patient recommendation rates were not associated with prescribing homeopathy.
We concluded that even infrequent homeopathy prescribing is strongly associated with poor performance on a range of prescribing quality measures, but not with overall patient recommendation or quality outcomes framework score. The association is unlikely to be a direct causal relationship, but may reflect underlying practice features, such as the extent of respect for evidence-based practice, or poorer stewardship of the prescribing budget.
Since our study was reported in almost all of the UK newspapers, it comes as no surprise that, in the interest of ‘journalistic balance’, homeopaths were invited to give their ‘expert’ opinions on our work.
Margaret Wyllie, head of the British Homeopathic Association, was quoted commenting: “This is another example of how real patient experience and health outcomes are so often discounted, when in actuality they should be the primary driver for research to improve our NHS services. This study provides no useful evidence about homeopathy, or about prescribing, and gives absolutely no data that can improve the health of people in the UK.”
The Faculty of Homeopathy was equally unhappy about our study and stated: “The study did not include any measures of patient outcomes, so it doesn’t tell us how the use of homeopathy in English general practice correlates with patients doing well or badly, nor with how many drugs they use.”
Cristal Summer from the Society of Homeopathy said that our research was just a rubbish bit of a study.
Peter Fisher, the Queen’s homeopath and the president of the Faculty of Homeopathy, stated: “We don’t know if these measures correlate with what matters to patients – whether they get better and have side-effects.”
A study aimed at determining whether GP practices that prescribe homeopathic preparations differ in their prescribing habits from those that do not prescribe homeopathics can hardly address these questions, Peter. A test of washing machines can hardly tell us much about the punctuality of trains. And an investigation into the risks of bungee jumping will not inform us about the benefits of regular exercise. Call me biased, but to me these comments indicate mainly one thing: HOMEOPATHS SEEM TO HAVE GREAT DIFFICULTIES UNDERSTANDING SCIENTIFIC PAPERS.
I much prefer the witty remarks of Catherine Bennett in yesterday’s Observer: Homeopath-GPs, naturally, have mustered in response and challenge Goldacre’s findings, with a concern for methodology that could easily give the impression that there is some evidential basis for their parallel system, beyond the fact that the Prince of Wales likes it. In fairness to Charles, his upbringing is to blame. But what is the doctors’ excuse?
Osteopathy is an odd alternative therapy. In many parts of the world it is popular; the profession differs dramatically from country to country; and there is not a single condition for which we could say that osteopathy out-performs other options. No wonder then that osteopaths would be more than happy to find a new area where they could practice their skills.
Perhaps surgical care is such an area?
The aim of this systematic review was to present an overview of published research articles within the subject field of osteopathic manipulative treatment (OMT) in surgical care. The authors evaluated peer-reviewed research articles published in osteopathic journals during the period 1990 to 2017. In total, 10 articles were identified.
Previous research has been conducted within the areas of abdominal, thoracic, gynecological, and/or orthopedic surgery. The studies included outcomes such as pain, analgesia consumption, length of hospital stay, and range of motion. Heterogeneity was identified in usage of osteopathic techniques, treatment duration, and occurrence, as well as in the osteopath’s experience.
The authors concluded that despite the small number of research articles within this field, both positive effects as well as the absence of such effects were identified. Overall, there was a heterogeneity concerning surgical contexts, diagnoses, signs and symptoms, as well as surgical phases in current interprofessional osteopathic publications. In this era of multimodal surgical care, the authors concluded, there is an urgent need to evaluate OMT in this context of care and with a proper research approach.
This is an odd conclusion, if there ever was one!
The facts are fairly straight forward:
- Osteopaths would like to expand into the area of surgical care [mainly, I suspect, because it would be good for business]
- There is no plausible reason why OMT should be beneficial in this setting.
- Osteopaths are not well-trained for looking after surgical patients.
- Physiotherapists, however, are and therefore there is no need for osteopaths on surgical wards.
- The evidence is extremely scarce.
- The available trials are of poor quality.
- Their results are contradictory.
- Therefore there is no reliable evidence to show that OMT is effective.
The correct conclusion of this review should thus be as follows:
THE AVAILABLE EVIDENCE FAILS TO SHOW EFFECTIVENESS OF OMT. THEREFORE THIS APPROACH CANNOT BE RECOMMENDED.
End of story.
I have often criticised papers published by chiropractors.
This article is excellent and I therefore quote extensively from it.
The objective of this systematic review was to investigate, if there is any evidence that spinal manipulations/chiropractic care can be used in primary prevention (PP) and/or early secondary prevention in diseases other than musculoskeletal conditions. The authors conducted extensive literature searches to locate all studies in this area. Of the 13.099 titles scrutinized, 13 articles were included (8 clinical studies and 5 population studies). They dealt with various disorders of public health importance such as diastolic blood pressure, blood test immunological markers, and mortality. Only two clinical studies could be used for data synthesis. None showed any effect of spinal manipulation/chiropractic treatment.
The authors concluded that they found no evidence in the literature of an effect of chiropractic treatment in the scope of PP or early secondary prevention for disease in general. Chiropractors have to assume their role as evidence-based clinicians and the leaders of the profession must accept that it is harmful to the profession to imply a public health importance in relation to the prevention of such diseases through manipulative therapy/chiropractic treatment.
In addition to this courageous conclusion (the paper is authored by a chiropractor and published in a chiro journal), the authors make the following comments:
Beliefs that a spinal subluxation can cause a multitude of diseases and that its removal can prevent them is clearly at odds with present-day concepts, as the aetiology of most diseases today is considered to be multi-causal, rarely mono-causal. It therefore seems naïve when chiropractors attempt to control the combined effects of environmental, social, biological including genetic as well as noxious lifestyle factors through the simple treatment of the spine. In addition, there is presently no obvious emphasis on the spine and the peripheral nervous system as the governing organ in relation to most pathologies of the human body.
The ‘subluxation model’ can be summarized through several concepts, each with its obvious weakness. According to the first three, (i) disturbances in the spine (frequently called ‘subluxations’) exist and (ii) these can cause a multitude of diseases. (iii) These subluxations can be detected in a chiropractic examination, even before symptoms arise. However, to date, the subluxation has been elusive, as there is no proof for its existence. Statements that there is a causal link between subluxations and various diseases should therefore not be made. The fourth and fifth concepts deal with the treatment, namely (iv) that chiropractic adjustments can remove subluxations, (v) resulting in improved health status. However, even if there were an improvement of a condition following treatment, this does not mean that the underlying theory is correct. In other words, any improvement may or may not be caused by the treatment, and even if so, it does not automatically validate the underlying theory that subluxations cause disease…
Although at first look there appears to be a literature on this subject, it is apparent that most authors lack knowledge in research methodology. The two methodologically acceptable studies in our review were found in PubMed, whereas most of the others were identified in the non-indexed literature. We therefore conclude that it may not be worthwhile in the future to search extensively the non-indexed chiropractic literature for high quality research articles.
One misunderstanding requires some explanations; case reports are usually not considered suitable evidence for effect of treatment, even if the cases relate to patients who ‘recovered’ with treatment. The reasons for this are multiple, such as:
- Individual cases, usually picked out on the basis of their uniqueness, do not reflect general patterns.
- Individual successful cases, even if correctly interpreted must be validated in a ‘proper’ research design, which usually means that presumed effect must be tested in a properly powered and designed randomized controlled trial.
- One or two successful cases may reflect a true but very unusual recovery, and such cases are more likely to be written up and published as clinicians do not take the time to marvel over and spend time on writing and publishing all the other unsuccessful treatment attempts.
- Recovery may be co-incidental, caused by some other aspect in the patient’s life or it may simply reflect the natural course of the disease, such as natural remission or the regression towards the mean, which in human physiology means that low values tend to increase and high values decrease over time.
- Cases are usually captured at the end because the results indicate success, meaning that the clinical file has to be reconstructed, because tests were used for clinical reasons and not for research reasons (i.e. recorded by the treating clinician during an ordinary clinical session) and therefore usually not objective and reproducible.
- The presumed results of the treatment of the disease is communicated from the patient to the treating clinician and not to a third, neutral person and obviously this link is not blinded, so the clinician is both biased in favour of his own treatment and aware of which treatment was given, and so is the patient, which may result in overly positive reporting. The patient wants to please the sympathetic clinician and the clinician is proud of his own work and overestimates the results.
- The long-term effects are usually not known.
- Further, and most importantly, there is no control group, so it is impossible to compare the results to an untreated or otherwise treated person or group of persons.
Nevertheless, it is common to see case reports in some research journals and in communities with readers/practitioners without a firmly established research culture it is often considered a good thing to ‘start’ by publishing case reports.
Case reports are useful for other reasons, such as indicating the need for further clinical studies in a specific patient population, describing a clinical presentation or treatment approach, explaining particular procedures, discussing cases, and referring to the evidence behind a clinical process, but they should not be used to make people believe that there is an effect of treatment…
For groups of chiropractors, prevention of disease through chiropractic treatment makes perfect sense, yet the credible literature is void of evidence thereof. Still, the majority of chiropractors practising this way probably believe that there is plenty of evidence in the literature. Clearly, if the chiropractic profession wishes to maintain credibility, it is time seriously to face this issue. Presently, there seems to be no reason why political associations and educational institutions should recommend spinal care to prevent disease in general, unless relevant and acceptable research evidence can be produced to support such activities. In order to be allowed to continue this practice, proper and relevant research is therefore needed…
All chiropractors who want to update their knowledge or to have an evidence-based practice will search new information on the internet. If they are not trained to read the scientific literature, they might trust any article. In this situation, it is logical that the ‘believers’ will choose ‘attractive’ articles and trust the results, without checking the quality of the studies. It is therefore important to educate chiropractors to become relatively competent consumers of research, so they will not assume that every published article is a verity in itself…
END OF QUOTES
YES, YES YES!!!
I am so glad that some experts within the chiropractic community are now publishing statements like these.
This was long overdue.
How was it possible that so many chiropractors so far failed to become competent consumers of research?
Do they and their professional organisations not know that this is deeply unethical?
Actually, I fear they do and did so for a long time.
Why then did they not do anything about it ages ago?
I fear, the answer is as easy as it is disappointing:
If chiropractors systematically trained to become research-competent, the chiropractic profession would cease to exist; they would become a limited version of physiotherapists. There is simply not enough positive evidence to justify chiropractic. In other words, as chiropractic wants to survive, it has little choice other than remaining ignorant of the current best evidence.
This week, I find it hard to decide where to focus; with all the fuzz about ‘Homeopathy Awareness Week’ it is easy to forget that our friends, the chiros are celebrating Chiropractic Awareness Week (9-15 April). On this occasion, the British Chiropractic Association (BCA), for instance, want people to keep moving to make a positive impact on managing and preventing back and neck pain.
Good advice! In a recent post, I even have concluded that people should “walk (slowly and cautiously) to the office of their preferred therapist, have a little rest there (say hello to the staff perhaps) and then walk straight back home.” The reason for my advice is based on the fact that there is precious little evidence that the spinal manipulations of chiropractors make much difference plus some worrying indications that they may cause serious damage.
It seems to me that, by focussing their PR away from spinal manipulations and towards the many other things chiropractors sometimes do – they often call this ‘adjunctive therapies’ – there is a tacit admission here that the hallmark intervention of chiros (spinal manipulation) is of dubious value.
A recent article entitled ‘Spinal Manipulative Therapy and Other Conservative Treatments for Low Back Pain: A Guideline From the Canadian Chiropractic Guideline Initiative’ seems to confirm this impression. Its objective was to develop a clinical practice guideline on the management of acute and chronic low back pain (LBP) in adults. The specific aim was to develop a guideline to provide best practice recommendations on the initial assessment and monitoring of people with low back pain and address the use of spinal manipulation therapy (SMT) compared with other commonly used conservative treatments.
The topic areas were chosen based on an Agency for Healthcare Research and Quality comparative effectiveness review, specific to spinal manipulation as a non-pharmacological intervention. The panel updated the search strategies in Medline and assessed admissible systematic reviews and randomized controlled trials. Evidence profiles were used to summarize judgments of the evidence quality and link recommendations to the supporting evidence. Using the Evidence to Decision Framework, the guideline panel determined the certainty of evidence and strength of the recommendations. Consensus was achieved using a modified Delphi technique. The guideline was peer reviewed by an 8-member multidisciplinary external committee.
For patients with acute (0-3 months) back pain, we suggest offering advice (posture, staying active), reassurance, education and self-management strategies in addition to SMT, usual medical care when deemed beneficial, or a combination of SMT and usual medical care to improve pain and disability. For patients with chronic (>3 months) back pain, we suggest offering advice and education, SMT or SMT as part of a multimodal therapy (exercise, myofascial therapy or usual medical care when deemed beneficial). For patients with chronic back-related leg pain, we suggest offering advice and education along with SMT and home exercise (positioning and stabilization exercises).
The authors concluded that a multimodal approach including SMT, other commonly used active interventions, self-management advice, and exercise is an effective treatment strategy for acute and chronic back pain, with or without leg pain.
I find this paper most interesting and revealing. Considering that it originates from the ‘Canadian Chiropractic Guideline Initiative’, it is remarkably shy about recommending SMT – after all their vision is “To enhance the health of Canadians by fostering excellence in chiropractic care.” They are thus not likely to be overly critical of the treatment chiropractors use most, i. e. SMT.
Perhaps this is also the reason why, in their conclusion, they seem to have rather a large blind spot, namely the risks of SMT. I have commented on this issue more often than I care to remember. Most recently, I posted this:
The reason why my stance, as expressed on this blog and elsewhere, is often critical about certain alternative therapies is thus obvious and transparent. For none of them (except for massage) is the risk/benefit balance positive. And for spinal manipulation, it even turns out to be negative. It goes almost without saying that responsible advice must be to avoid treatments for which the benefits do not demonstrably outweigh the risks.
HAPPY CHIROPRACTIC AWARENESS WEEK EVERYONE!
Prof Ke’s Asante Academy (Ke claims that asante is French and means good health – wrong, of course, but that’s the least of his errors) offers many amazing things, and I do encourage you to have a look at his website. Prof Ke is clearly not plagued by false modesty; he informs us that “I am proud to say that we have gained a reputation as one of the leading Chinese Medicine clinics and teaching institutes in the UK and Europe. One CEO from a leading Acupuncture register commented that we were the best in the country. One doctor gave up his medical job in a European country to come study Chinese medicine at Middlesex University (our partner) – he said simply it was because of Asante. Our patients, from royalty and celebrities to hard working people all over the world, have praised us highly for successfully treating their wide-ranging conditions, including infertility, skin problems, pain and many others. We are also very pleased to have pioneered Acupuncture service in the NHS and for over a decade we have seen tens of thousands of NHS patients in hospitals.”
He provides treatments for any condition you can imagine, courses in various forms of TCM, a range of videos (they are particularly informative), as well as interesting explanations and treatment plans for dozens of conditions. From the latter, I have chosen just two diseases and quote some extracts to give you a vivid impression of the Ke’s genius:
There are some ways in which Chinese medicine can help cancer cases where Western medicine cannot. Various herbal prescriptions have been shown to help in bolstering the immune system and some herbs can actually attack the abnormal cells and viruses which are responsible for certain types of cancer.
Chinese Medicine treatment aims first to increase the body’s own defence mechanisms, then to kill the cancer cells. Effective though radiotherapy and chemotherapy may be, they tend to have a drastic effect on the body generally and patients often feel very tired and weak, suffer from stress, anxiety, fear, insomnia and loss of appetite. Chinese Medicine practitioners regard strengthening the patient psychologically and physically to be of primary importance.
Chinese Medicine herbal remedies can help reduce or eliminate the side-effects from radiotherapy or chemotherapy. Astragalus will help raise the blood cell count, the sickness caused by chemotherapy can be relieved with fresh ginger and orange peel, and acupuncture can also help. To attack the cancer itself, depending on type and location, different herbs will be used.
A Chinese Medicine practitiioner will decide whether the illness is the result of qi energy deficiency, blood deficiency or yin or yang deficiency. Ginseng,astragalus, Chinese angelica, cooked rehmannia root, wolfberry root, Chinese yam and many tonic herbs may be used. But it is vital to remember that no one tonic is good for everybody. All treatments are dependent upon the individual. Some anti-cancer herbs used are very strong and sometimes make people sick, but this is because one poison is being used against another. How they work, and how clinically effective they are, is still being researched. No claims can be made for them based on modern scientific evaluation.
Acupuncture and meditation are also very important parts of the Chinese Medicine traditional approach to the treatment of cancer. These alleviate pain and induce a sense of calmness, instill confidence and build up the spirit of the body, so that patients do not need to take so many painkillers. In China, they have many meditation programmes which are used to treat cancer.
Chinese Medicine herbal treatment for meningitis has been very successful in China. In the recent past there were many epidemics, particularly in the north, and the hospitals routinely used Chinese herbs as treatment, with a high degree of success. One famous remedy in Chinese Medicine is called White Tiger Decoction, the main ingredients of which are gypsum and rice. These are simple things but they reduce the high fever and clear the infection from the brain. Modern medicine and Chinese Medicine used together is the most effective treatment.

Ghosh, I am so glad that finally someone explained these things to me, and so logically and simply too. I used to have doubts about the value of TCM for these conditions, but now I am convinced … so much so that I go on Medline to find the scientific work of Prof Ke. But what, what, what? That is not possible; such a famous professor and no publications?
I conclude that my search skills are inadequate and throw myself into studying the plethora of courses Ke offers for the benefit of mankind:
Since 2000, Asanté Academy has officially collaborated with Middlesex University in running and teaching the BSc and MSc in Traditional Chinese Medicine.
- BSc Degrees in Acupuncture and Traditional Chinese Medicine
- MSc Degree in Chinese Medicine
- Professional Practice in Herbal Medicine, Chinese Herbal Medicine and Acupuncture
But perhaps this is a bit too arduous; maybe so-called diploma courses suit me better? Personally, I am tempted by the ‘24-day Certificate Course in TCM Acupuncture‘ – it’s a bargain, just £ 2,880!
Prof Ke, if you read these lines, would you please tell us where and when you got your professorship? Your otherwise ostentatious website seems to fail to disclose this detail.
Did you know that chiropractic is a religion?
Well, not quite but almost.
DD Palmer seriously toyed with the idea of turning chiropractic into a religion.
And rightly so!
In the absence of evidence, belief is everything.
And this is why, to this day, so many chiropractors bank (a most appropriate term in this context!) on belief rather than evidence.
Look, for instance at this lovely advertisement I found on Twitter (there are many more, but this one has to stand for the many).
Seven common benefits of chiropractic care!?!
Beneath the picture of a pathologically straight spine – if that is what chiro does to you, avoid it at all cost! – we see the name of the ‘doctor’ who seems to have designed this impressive picture. ‘Dr’ Schluter is even more versatile than his pretty advertisement implies; he also seems to treat newborn babies! And on his website he also tells us that he is able to treat allergies:
You may be surprised to find that chiropractic can do a great deal to alleviate some allergies. Allergies are very common and we become so used to their effect on us that we tend to ignore their symptoms. And many people are unaware of the gradual decline in health that results. Chiropractic treatment didn’t necessarily set out specifically to provide care for allergies, but due to the nature of the chiropractic care and its effect on the nervous system, it has been shown to help.
If we look at some of the common signs of allergies we find that they include some unexpected examples. Not only do we find the usual ones – asthma, sinus congestion, sneezing, itchy eyes, skin rashes and running nose – but also weight gain, Acne and even fluid retention and heartburn.
Many people approach the problem of allergies as though all allergens affect everyone in the same way; this is not the case. Because we are individuals, different allergens affect each of us in differing ways. Some allergens affect some and not others. Consequently treating the condition must be approached on this basis of individuality.
It may not be the pet fur or dried saliva that is kicked up as your pooch washes and scratches; it may also not be the pollen, grass dust or other one of the many irritants in the air at any one time. It could be that due to a misalignment of the spine (or subluxation), mild though it may be, the nervous system is finding it difficult to help the body adapt to its surroundings and is therefore unable to deal with the necessary adjustments.
As an individual you need to treat your body’s physical and nervous system as such. You could be, without even being aware of it, in a generally stressed condition – this may be through lack of sleep, poor nutrition or any one of a combination of the many other stressors affecting us daily. Suddenly you find that with the first spring pollen dust that comes along you begin to wheeze and sneeze!
You may not have previously connected chiropractors and allergies but, for you or someone you know, the connection could help.
Schluter Chiropractic works on the principle of reducing interference so the nervous system and body can work better. Providing that any symptom or condition (including pain) is occurring as a result of nerve interference from vertebral subluxation, there is a very good chance that it will improve with chiropractic care.

Wise words indeed.
Like most chiros, ‘Dr’ Schulter seems to be a true miracle-worker; and because he can do miracles, he does not need to be rational or concerned about evidence or worried about telling the truth.
For Christ sake, it’s Easter!
We ought to show a bit of belief!!!
Because without it, the benefits of chiropractic would be just an illusion.
An announcement (it’s in German, I’m afraid) proudly declaring that ‘homeopathy fulfils the criteria of evidence-based medicine‘ caught my attention.
Here is the story:
In 2016, Dr. Melanie Wölk, did a ‘Master of Science’* at the ‘Donau University’ in Krems, Austria investigating the question whether homeopathy follows the rules of evidence-based medicine (EBM). She arrived at the conclusion that YES, IT DOES! This pleased the leading Austrian manufacturer of homeopathics (Dr Peithner) so much and so durably that, on 23 March 2018, he gave her a ‘scientific’ award (the annual Peithner award) for her ‘research’.
So far so good.
Her paper is unpublished, or at least not available on Medline; therefore, I am unable to evaluate it directly. All I know about it from the announcement is that she did her ‘research at the ‘Zentrum für Traditionelle Chinesische Medizin und Komplementärmedizin‘ of the said university. A quick Medline search revealed that this unit has never published anything, not a single paper, it seems! Disappointed I search for Dr. Christine Schauhuber, the leader of the unit; and again I find no Medline-listed publications in her name. My interim conclusion is thus that this institution might not be at the cutting edge of science.
But what do we know about Dr. Melanie Wölk’s award-winning master thesis *?
The announcement tells us that she investigated all RCTs published between 2010 and 2016. In addition, she evaluated:
- the ‘Swiss report’,
- the NHMRC report,
- Shang 2005,
- Ernst 2002,
- the Frass sepsis trial of 2005,
- Linde 1997 (why not Linde 1999? I ask myself; perhaps because this re-analysis of the same material came to a largly negative conclusion?)
On that basis, she arrived at her positive verdict – not just tentatively, but without doubt (“Das Ergebnis steht fest”).
Dr Peithner, the owner of the company and awarder of the prize, was quoted stating that this is a very important piece of work for homeopathy; it shows yet again what we see in our daily routine, namely that homeopathics are effective. Wölk’s investigation demonstrates furthermore that high-quality trials of homeopathy do exist, and that it is time to end the witch-hunt aimed at discrediting an effective therapy. Conventional medicine and homeopathy ought to finally work hand in hand – for the benefit of our patients. (“Für die Homöopathie ist das eine sehr wichtige Arbeit, die wieder zeigt, was wir in der ärztlichen Praxis täglich erleben, nämlich dass homöopathische Arzneimittel wirken. Wölks Untersuchung zeigt weiters deutlich, dass es sehr wohl hochqualitative Homöopathie-Studien gibt und es an der Zeit ist, die Hexenjagd zu beenden, mit der eine wirksame medizinische Therapie diskreditiert werden soll. Konventionelle Medizin und Homöopathie sollten endlich Hand in Hand arbeiten – zum Wohle der Patientinnen und Patienten.”)
I do hope that Dr Wölk uses the prize money (by no means a fortune; see photo) to buy some time for publishing her work (one of my teachers, all those years ago, used to say ‘unpublished research is no research’) so that we can all benefit from it. Until it becomes available, I should perhaps mention that the description of her methodology (publications between 2010 and 2016 [plus a few other papers that nicely fitted the arguments?]; including one Linde review and not his more recent re-analysis [see above]) does not inspire me to think that Dr Wölk’s research was anywhere near rigorous, systematic or complete. In the same vein, I am tempted to point out that the Swiss report is probably the very last document I would select, if I wanted to generate an objective picture about the value of homeopathy.
Taking all this into account, I conclude that we seem to be dealing here with a
- pseudo-prize (given by a commercial firm to further its business) for a piece of
- pseudo-research (the project seems to have been aimed to white-wash homeopathy) into
- pseudo-medicine (a treatment that has been tested extensively but has not been shown to work beyond placebo).

Chiropractic for kids? Yes, many chiropractors advocate (and earn good money with) it, yet it has been pointed out ad nauseam that the claim of being able of treating paediatric conditions is bogus (in fact, the BCA even lost a famous court case over this issue). But evidence does rarely seem to stop a chiro on a mission!
This website shows us how UK chiropractors plan to educate colleagues in ‘paediatric chiropractic’.

The event is hosted and organised by the ‘United Chiropractic Association UK’ (UCA), an organisation with a mission to ensure the public has access to vitalistic chiropractic care, which claims that chiropractors provide care that is safe. Because the techniques used by chiropractors are acquired over years of study and experience, chiropractors have an enviable safety record. In fact, in the words of a classic New Zealand study, chiropractic care is “remarkably safe.” Chiropractors use the latest methods. After years of study, licensing examinations and continuing education seminars, chiropractors in the United Kingdom are at the top of their game, using proven techniques and natural methods to help you get well and stay well.
The UCA is firmly rooted in the gospel of the founding fathers (D D Palmer, B J Palmer etc.): Chiropractic is concerned with the preservation and restoration of health, and focuses particular attention on the subluxation. A subluxation is a complex of functional and/or structural and/or pathological articular changes that compromise neural integrity and may influence organ system function and general health. A subluxation is evaluated, diagnosed, and managed through the use of chiropractic procedures based on the best available rational and empirical evidence. Subluxation is a fundamental axiom of the Chiropractic profession. The World Federation of Chiropractors (WFC) policy statement reaffirms the use of the term vertebral subluxation and it is defined succinctly and accepted by the World Health Organisation (WHO).
Thus, the UCA seems to subscribe to both principles of the Palmers. The first is subluxation and the second is profit.
Now, now, now – I must not be so sarcastic.
Try something constructive, Edzard!
You are absolutely correct, Edzard.
Here it is, my constructive contribution to this event:
I herewith offer the UCA to give two lectures during their course; one about the importance of critical thinking in healthcare, and one reviewing the evidence for and against chiropractic for paediatric conditions.
The media have (rightly) paid much attention to the three Lancet-articles on low back pain (LBP) which were published this week. LBP is such a common condition that its prevalence alone renders it an important subject for us all. One of the three papers covers the treatment and prevention of LBP. Specifically, it lists various therapies according to their effectiveness for both acute and persistent LBP. The authors of the article base their judgements mainly on published guidelines from Denmark, UK and the US; as these guidelines differ, they attempt a synthesis of the three.
Several alternative therapist organisations and individuals have consequently jumped on the LBP bandwagon and seem to feel encouraged by the attention given to the Lancet-papers to promote their treatments. Others have claimed that my often critical verdicts of alternative therapies for LBP are out of line with this evidence and asked ‘who should we believe the international team of experts writing in one of the best medical journals, or Edzard Ernst writing on his blog?’ They are trying to create a division where none exists,
The thing is that I am broadly in agreement with the evidence presented in Lancet-paper! But I also know that things are a bit more complex.
Below, I have copied the non-pharmacological, non-operative treatments listed in the Lancet-paper together with the authors’ verdicts regarding their effectiveness for both acute and persistent LBP. I find no glaring contradictions with what I regard as the best current evidence and with my posts on the subject. But I feel compelled to point out that the Lancet-paper merely lists the effectiveness of several therapeutic options, and that the value of a treatment is not only determined by its effectiveness. Crucial further elements are a therapy’s cost and its risks, the latter of which also determines the most important criterion: the risk/benefit balance. In my version of the Lancet table, I have therefore added these three variables for non-pharmacological and non-surgical options:
|EFFECTIVENESS ACUTE LBP||EFFECTIVENESS PERSISTENT LBP||RISKS||COSTS||RISK/BENEFIT BALANCE|
|Advice to stay active||+, routine||+, routine||None||Low||Positive|
|Education||+, routine||+, routine||None||Low||Positive|
|Superficial heat||+/-||Ie||Very minor||Low to medium||Positive (aLBP)|
|Exercise||Limited||+/-, routine||Very minor||Low||Positive (pLBP)|
|CBT||Limited||+/-, routine||None||Low to medium||Positive (pLBP)|
|Rehab||Ie||+/-||Minor||Medium to high||Questionable|
Routine = consider for routine use
+/- = second line or adjunctive treatment
Ie = insufficient evidence
Limited = limited use in selected patients
vfbmae = very frequent, minor adverse effects
sae = serious adverse effects, including deaths, are on record
aLBP = acute low back pain
The reason why my stance, as expressed on this blog and elsewhere, is often critical about certain alternative therapies is thus obvious and transparent. For none of them (except for massage) is the risk/benefit balance positive. And for spinal manipulation, it even turns out to be negative. It goes almost without saying that responsible advice must be to avoid treatments for which the benefits do not demonstrably outweigh the risks.
I imagine that chiropractors, osteopaths and acupuncturists will strongly disagree with my interpretation of the evidence (they might even feel that their cash-flow is endangered) – and I am looking forward to the discussions around their objections.
At least this is what the authors of this new study want us to believe.
But are they right?
This RCT is entitled ‘Efficacy and tolerability of a complex homeopathic drug in children suffering from dry cough-A double-blind, placebo- controlled, clinical trial’. It recruited children suffering from acute dry cough to assess the efficacy and tolerability of a complex homeopathic remedy in liquid form (Drosera, Coccus cacti, Cuprum Sulfuricum, Ipecacuanha = Monapax syrup, short: verum).
The authors stated that “preparations of Drosera, Coccus cacti, Cuprum sulfuricum, and Ipecacuanha are well-known antitussives in homeopathic medicine. Each of them is connected with special subtypes of cough. Drosera is intended for inflammations of the respiratory tract, especially for whooping cough. Coccus cacti is intended for inflammations of the nasopharyngeal space and the respiratory tract. Cuprum sulfuricum is intended for spasmodic coughing at night. Ipecacuanha is intended for bronchitis, bronchial asthma, and whooping cough. The complex homeopathic drug explored in this trial consists of all four of these active substances.”
According to the authors of the paper, “the primary objective of the trial was to demonstrate the superiority of verum compared to the placebo”.
A total of 89 children, enrolled in the Ukraine between 15/04/2008 and 26/05/2008 in 9 trial centres, received verum and 91 received placebo daily for 7 days (age groups 0.5–3, 4–7 and 8–12 years). The trial was conducted using an adaptive 3-stage group sequential design with possible sample size adjustments after the two planned interim analyses. The inverse normal method of combining the p-values from all three stages was used for confirmatory hypothesis testing at the interim analyses as well as at the final analysis. The primary efficacy variable was the improvement of the Cough Assessment Score. Tolerability and compliance were also assessed. A confirmatory statistical analysis was performed for the primary efficacy variable and a descriptive analysis for the secondary parameters.
A total of 180 patients (89 in the verum and 91 in the placebo group) evaluable according to the intention-to-treat principle were included in the trial. The Cough Assessment Score showed an improvement of 5.2 ± 2.6 points for children treated with verum and 3.2 ± 2.6 points in the placebo group (p < 0.0001). The difference of the least square means of the improvements was 1.9 ± 0.4. The effect size of Cohen´s d was d = 0.77. In all secondary parameters the patients in the verum group showed higher rates of improvement and remission than those in the placebo group. In 15 patients (verum: n = 6; placebo: n = 9) 18 adverse drug reactions of mild or moderate intensity were observed.
The authors concluded that the administering verum resulted in a statistically significantly greater improvement of the Cough Assessment Score than the placebo. The tolerability was good and not inferior to that of the placebo.
This study seems fairly rigorous. What is more, it has been published in a mainstream journal of reasonably high standing. So, how can its results be positive? We all know that homeopathy does not work, don’t we?
Are we perhaps mistaken?
Are highly diluted homeopathic remedies effective after all?
I don’t think so.
Let me explain to you a few points that raise my suspicions about this study:
- It was conducted 10 years ago; why did it take that long to get it published?
- I don’t think highly of a study with “the primary objective … to demonstrate the superiority” of the experimental interventions. Scientists use RCTs for testing efficacy and pseudo-scientist use it for demonstrating it, I think.
- The study was conducted in the Ukraine in 9 centres, yet no Ukrainian is an author of the paper, and there is not even an acknowledgement of these primary investigators.
- The ‘adaptive 3-stage group sequential design with possible sample size adjustments’ sounds very odd to me, but I may be wrong; I am not a statistician.
- We learn that 180 patients were evaluated, but not how many were entered into the trial?
- The Cough Assessment Score is not a validated outcome measure.
- Was the verum distinguishable from the placebo? It would be easy to test whether the patients/parents were truly blinded. Yet no such results were included.
- The trial was funded by the manufacturer of the homeopathic remedy.
- The paper has three authors 1)Hans W. Voß has no conflict of interest to declare. 2) Rainer Brünjes is employed at Cassella-med, the marketing authorisation holder of the study product. 3) Andreas Michalsen has consulted for Cassella-med and participated in advisory boards.
I know, homeopathy fans will think I am nit-picking; and perhaps they are correct. So, let me tell you why I really do strongly reject the notion that this study shows or even suggests that highly diluted homeopathic remedies are more than placebos.
The remedy used in this study is composed of Drosera 0,02 g, Hedera helix Ø 0,04 g, China D1 0,02 g, Coccus cacti D1 0,04 g, Cuprum sulfuricum D4 2,0 g, Ipecacuanha D4 2,0 g, Hyoscyamus D4 2,0 g.
In case you don’t know what ‘Ø’ stands for (I don’t blame you, hardly anyone outside the world of homeopathy does), it signifies a ‘mother tincture’, i. e. an undiluted herbal extract; and ‘D1’ signifies diluted 1:10. This means that the remedy may be homeopathic from a regulatory point of view, but for all intents and purposes it is a herbal medicine. It contains an uncounted amount of active compounds, and it is therefore hardly surprising that it might have pharmacological effects. In turn, this means that this trial does by no means overturn the fact that highly diluted homeopathic remedies are pure placebos.
It’s a pity, I find, that the authors of the paper fail to explain this simple fact in full detail – might one think that they intentionally aimed at misleading us?
