I have met many acupuncturists who think that homeopathy is bunk. Similarly, I have met many homeopaths who are convinced that acupuncture is a placebo therapy. And, I have met some (not many) practitioners of so-called alternative medicine (SCAM) who think so highly of both SCAMs that they combine the two into one handy treatment: HOMEOPUNCTURE.

I had almost forgotten (or is supressed the correct verb?) but, to be entirely truthful, a long time ago (in the mid 1970s), I even experimented with this odd therapy myself. When I worked as a junior doctor in a homeopathic hospital, several of my collegues practised homeopuncture and taught me how to do it. Essentially, you inject homeopathic remedies into acupuncture points. My colleagues told me that this approach is more powerful than each method alone. I tried it several times but remained unconvinced.

Recently, a German Heilpraktiker (Andreas Maier), reminded me of all this. Here is what he states on his website about homeopuncture:

In traditional Chinese medicine, acupuncture in addition to the herb medicine as well as certain movement therapies (eg. B. Gong Qi) constituting an important element in the treatment of diseases.

By stimulating energy points with the help of fine needles will then attempts to harmonize the flow of vital energy. a disruption of vital energy because (also called Qi), is considered in Chinese medicine as a cause of any disease.

Only when the energy flows freely through all the tissues and organs of the body, the organism can develop normally and is healthy. A similar approach is also the Homeopathy, which originated at the other end of the world, namely in Germany.

Samuel Hahnemann (1755 – 1843), the discoverer of this method of healing, also saw a failure of the life force as a pathogenic factor.

By smallest stimuli the homeopath tries to eliminate these disease-causing disorder and bring about healing. Unlike in the acupuncture reduced drug doses to be used strictly in accordance with the  principle of similarity  are selected.

Mid-19th century was the German physician Dr. August consecration firmly (1840- 1896) that disease with painful spots may accompany the body.

These pain points are often far from the actual disease process. The phenomenon was known to the Chinese for thousands of years in Europe, however, no one had yet busy. Dr. Weihe, himself a keen homeopath, was in the treatment of his patients finally see that by the suitably chosen homeopathic healed not only the disease, but also disappeared the painfulness of the points.

It was surprising that certain homeopathic remedies appear to be well-defined points had a direct bearing on the body.

A few years later, the Chinese medicine and acupuncture also reached the European continent, they took Weihe discoveries closer look. A comparison of the so-called consecration points with acupuncture points showed significant matches.

The more than 300 known Weihe points are also used therapeutically since both diagnosis. Because they can provide information on the pathological processes in the body and on the displayed homeopathic. thus the Homöopunktur brings together the findings from Chinese medicine and homeopathy. The treatment can be done differently.

On the one hand the consecration points can be traditionally stimulated with fine needles, concomitant administration of homeopathic medicine. With the help of injection preparations, means may also be injected directly to the point.


(sorry about my friend’s poor English; I hope you could make sense of it)

I don’t think I need to tell you what the evidence tells us about homeopuncture. Yes, you guessed it: nothing! But the idea of combining SCAMs is fascinating nevertheless. So, let me suggest a few further SCAM combinations that might be attractive:

  • acupuncture + massage (sorry, that already exists under the name of shiatsu)
  • colonic irrigation + coffea (that to is already taken by the Gerson guys)
  • art therapy + homeopathy (too late: this one too already exists; painting homeopathy on the body surface)
  • detox + meditation (no, the health retreat/wellness entrepreneurs might get upset)

I am clearly not very successful at finding viable SCAM combinations. Let’s look for something innovative, something that nobody has yet thought of. How about:

  • homeo-laugh (homeopathy followed by an explanation what homeopathy is resulting in laughter; not sure that this would sell all that well)
  • kinesiology colour taping (instead of using random colours for kinesiology tape, this approach uses the wisdom of coulourtherapists to match the patient’s individual colour requirements; this means the therapists needs dual qualifications and can thus charge double – I think that might be attractive!)
  • autologous slapping therapy (this combination of slapping and autologous blood therapy (ABT) means the therapist has to hit so hard that the patient develops sizable haematomas which are the ABT part of the intervention; perhaps a bit risky, as some patients might call the police)
  • effective reverse energy transfer counselling, ERETC (the patients is counselled that his money can, with the help of the therapist, be converted into pure healing energy; to make it work, the patient needs to transfer it to the account of the therapist – the more the better)

I think I like ERECT best; in fact, I will start work on it straight away. It still needs to be perfected, but once it’s up and running, it will be just great and, as the name already makes clear, effective – not for the patient, but for the therapist!

I live (most of my time) in the UK, a country where the media interest in so-called alternative medicine (SCAM) is considerable. Years ago, the UK press used to be very much in favour of SCAM. In 2000, we showed that the level of interest was huge and the reporting was biased. Here is our short BMJ paper on the subject:

The media strongly influences the public’s view of medical matters. Thus, we sought to determine the frequency and tone of reporting on medical topics in daily newspapers in the United Kingdom and Germany. The following eight newspapers were scanned for medical articles on eight randomly chosen working days in the summer of 1999: the Times, the Independent, the Daily Telegraph, and the Guardian in the United Kingdom, and Frankfurter Allgemeine Zeitung, Süddeutsche Zeitung, Frankfurter Rundschau, and Die Welt in Germany. All articles relating to medical topics were extracted and categorised according to subject, length, and tone of article (critical, positive, or neutral).

A total of 256 newspaper articles were evaluated. The results of our analysis are summarised in the table. We identified 80 articles in the German newspapers and 176 in the British; thus, British newspapers seem to report on medical topics more than twice as often as German broadsheets. Articles in German papers are on average considerably longer and take a positive attitude more often than British ones. Drug treatment was the medical topic most frequently discussed in both countries (51 articles (64%) in German newspapers and 97 (55%) in British). Surgery was the second most commonly discussed medical topic in the UK newspapers (32 articles; 18%). In Germany professional politics was the second most commonly discussed topic (11 articles; 14%); this category included articles about the standing of the medical profession, health care, and social and economic systems—that is, issues not strictly about treating patients.

Because our particular interest is in complementary medicine, we also calculated the number of articles on this subject. We identified four articles in the German newspapers and 26 in the UK newspapers. In the United Kingdom the tone of these articles was unanimously positive (100%) whereas most (3; 75%) of the German articles on complementary medicine were critical.

This analysis is, of course, limited by its small sample size, the short observation period, and the subjectivity of some of the end points. Yet it does suggest that, compared with German newspapers, British newspapers report more frequently on medical matters and generally have a more critical attitude (table). German newspapers frequently discuss medical professional politics, a subject that is almost totally absent from newspapers in the United Kingdom.

The proportion of articles about complementary medicine seems to be considerably larger in the United Kingdom (15% v 5%), and, in contrast to articles on medical matters in general, reporting on complementary medicine in the United Kingdom is overwhelmingly positive. In view of the fact that both healthcare professionals and the general public gain their knowledge of complementary medicine predominantly from the media, these findings may be important.2,3


Reporting on medical topics by daily newspapers in the United Kingdom and Germany, 1999


United Kingdom (n=176) Germany (n=80)
Mean No articles/day 5.5 2.5
Mean (SD) No words/article 130 (26) 325 (41)
Ratio of positive articles to critical articles* 1.0 3.2

Even though I have no new data on this, my impression is that things have since changed. It seems that the UK press has become more objective and are now reporting more critical comments on SCAM. While this is most welcome, of course, one feature is still deplorable, in my view: journalists’ obsession with ‘balance’.

A recent example might explain this best. The ‘i’ newspaper published an article about homeopathy which was well-written and thoroughly researched. It explained the current best evidence on the subject and made it quite clear why homeopathy is not a reasonable therapy for any condition. But then, towards the end of the article, the journalist added this section:

Dr Lise Hansen, a veterinary homeopath based in London and author of a forthcoming book, The Complete Book of Cat and Dog Health, argues that scientists have shown how homeopathy works. She cites a paper by Luc Montagnier, the French virologist who won a Nobel Prize in 2008 for his role in discovering HIV. The following year, he published evidence of his discovery of “electromagnet signals that are produced by nanostructures derived from bacterial DNA at high aqueous dilutions”. “Mainstream medicine is about chemistry, homeopathy is physics and scientists have only recently begun to study these nanostructures,” Hansen says.

Basically, the reader is left with the impression that homeopathy might be fine after all, and that science will soon be able to catch up with it. In the interest of balance, the journalist thus confused her readers and misled the public.


Journalists are obviously taught to always cover ‘both sides’ of their stories, and they adhere to this dogma no matter what. In most instances, this works out well, because in most cases there are two sides.

But not always!

When there is a strong consensus supported by facts, science and reproducible findings, the other side ceases to have a reasonable point. There simply is no reasonable ‘other side’ when we consider global warming, evolution, the Holocaust, and many other subjects. Of course, one can always find some loon who claims the earth is flat, or that cancer is a Jewish plot against public health. But these arguments lack reason and integrity – to dish them out without anything remotely resembling a ‘fact check’ is not just annoying but harmful.

Journalists should, in my view, be more responsible, check the facts, and avoid false balance. I know this will often entail much more work, but they owe it to their readers and to the reputation of their profession.

I am not usually a vulgar person, and I do apologise for the title of this post. But, in view of todays’ subject, some vulgarity seems almost unavoidable. This post is about homeopathic provings. In my book, I explain them in some detail:

The term ‘proving’ is a mis-translation of Hahnemann’s term ‘Pruefung’ which means ‘a test’. The English term wrongly implies that some fact is being proven. According to the International Dictionary of Homeopathy, provings (also known as ‘homeopathic pathogenetic trials’ or ‘Arzneimittelpruefung’ as Hahnemann called them), are defined as the process of determining the medicinal properties of a substance; testing in material dose, mother tincture or potency, by administration to healthy volunteers, to elicit effects from which the therapeutic potential, or material medica of the substance may be derived.

In order to individualise their treatment according to the ‘like cures like’ principle, homeopaths need to know what symptoms, or ‘artificial disease’, can be caused by the substances they prescribe. If they treat a patient who suffers from running eyes and nose, for instance, they would be looking for a substance that causes runny eyes and nose in healthy individuals. This is why remedies based on onion might be used to treat conditions like the common cold or hay fever.

But most patients’ complaints are usually a lot more complex. For instance, a person might suffer from frequently runny eyes and nose together with a whole host of other symptoms, many of which might seem trivial or irrelevant to conventional doctors but, for a homeopath, all complaints and patient characteristics are potentially important.

The first proving in the history of homeopathy was Hahnemann’s quinine experiment, which convinced him that he had discovered that this malaria cure causes the symptoms of malaria when taken by a healthy individual. From this observation he deduced that any substance causing symptoms in a healthy person could be used to cure these same symptoms when they occur in a patient.

Provings are normally conducted by administering a mother tincture or a low potency to healthy volunteers who subsequently note in minute detail all sensations, symptoms, emotions and thoughts that occur to them while taking it. These are then carefully registered and eventually form the ‘drug picture’ of that substance.

As a day goes by, we all experience, of course, all sorts of sensations without apparent reason, whether we have taken a medicine or not. Therefore, simple provings are not reliable and might not describe the specific symptoms caused by the substance in question. Realising this problem, most homeopaths now advocate conducting provings in a placebo-controlled manner hoping that this method might generate only symptoms which are specific to the tested substance.

Today thousands of provings have been carried out; most of them are of very low methodological quality. Their results have been published in reference books called ‘repertories’. Homeopaths, once they have noted the full range of characteristics of a patient, can look up the optimal remedy for each individual case. To ease this process even further, sophisticated computer programs are available.

So, essentially, homeopathic provings are experiments where homeopaths give a (often highly diluted/potentised) substance to healthy volunteers and ask them to monitor all sensations that follow. These symptoms are then recorded and eventually form the ‘drug picture’ of a homeopathic remedy. When prescribing a remedy, homeopaths essentially try to match the patient’s symptoms with the drug picture. This is why provings and drug pictures are so very important to classical homeopaths.

Now, imagine that you have just swallowed a substance and start paying attention to all the sensations you feel. As I am writing these lines, I would note all of the following:

  • mild mental irritation,
  • impatience,
  • neck pain,
  • back pain,
  • heavy feet,
  • hot feet,
  • slight ringing in right ear,
  • pressure on abdomen,
  • tickling nose,
  • sweaty hands,
  • acid taste in mouth,
  • need to pass urine,
  • feeling of need to wash hands,
  • itchy scalp,
  • acidity in stomach,
  • itch over right eyebrow.

These are just some of the sensations that come and go with everyday life; they are devoid of any medical meaning or importance. In homeopathy, however, they are elevated to something of fundamental relevance. As I have just had a cup of coffee, the above list could even be seen as a proving of coffea and a contribution to its drug picture. In turn, this would then determine how homeopaths prescribe homeopathic coffea. If others generated similar symptoms after coffee, some of the symptoms listed above might become the part of the accepted drug picture of coffea.

Many of the homeopathic provings are indeed based on little more than that. Modern provings are often conducted a little more rigorously, but there are tens of thousands of different remedies and the drug pictures of many are hardly different from my above-described proving of coffea. If you find this hard to believe, see what two homeopaths noted during a homeopathic proving of another remedy:

Domination and abuse are so intense that they lead to total suppression of oneself. The person develops intense hatred towards  the dominant person, as though they are being tortured. The intensity of the suppressed emotions produces other emotional, mental and physical symptoms: suicidal thoughts, aversion to company, panic attacks with lot of anxiety, low self confidence, arrested mental development, heart palpitations with anxiety, indisposed to talk, aversion to work, compulsive disorder of work, etc.

Low self-esteem and low self-confidence are associated with dependency and fear of failure.There is intense fear of failure and inadequacy, which leads to complete helplessness. This remedy also has aversion to self and a low self image. In this remedy, there are dreams/ thoughts of toilets.

Other symptoms include:

  • Ailments from sexual abuse and rape
  • Mind; colors; charmed by; golden/ colors; desires; golden
  • Delusion or image that body parts/ arms/ legs are smaller, and shortened
  • Dreams lascivious/ seduction/ necked people/ prostitution/ violent sex; Dreams; lascivious, voluptuous; partner, frequent change of/ voluptuous; perverse; girls, about little)
  • Dreams of dogs/ cats, felines
  • Fastidious; appearance, about; personal
  • Music; desires; drums

Believe it or not, the above text is taken from a published proving of excrementum canium – yes: dog shit!

This leads me to conclude that homeopathic provings (and, as provings are the basis for all homeopathy, with it the entire field of homeopathy) are BS.

The World Federation of Chiropractic (WFC) claim to have been at the forefront of the global development of chiropractic. Representing the interests of the profession in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions. Now, the WFC have formulated 20 principles setting out who they are, what they stand for, and how chiropractic as a global health profession can, in their view, impact on nations so that populations can thrive and reach their full potential. Here are the 20 principles (in italics followed by some brief comments by me in normal print):

1. We envision a world where people of all ages, in all countries, can access the benefits of chiropractic.

That means babies and infants! What about the evidence?

2. We are driven by our mission to advance awareness, utilization and integration of chiropractic internationally.

One could almost suspect that the drive is motivated by misleading the public about the risks and benefits of spinal manipulation for financial gain.

3. We believe that science and research should inform care and policy decisions and support calls for wider access to chiropractic.

If science and research truly did inform care, it would soon be chiropractic-free.

4. We maintain that chiropractic extends beyond the care of patients to the promotion of better health and the wellbeing of our communities.

The best example to show that this statement is a politically correct platitude is the fact that so many chiropractors are (educated to become) convinced that vaccinations are undesirable or harmful.

5. We champion the rights of chiropractors to practice according to their training and expertise.

I am not sure what this means. Could it mean that they must practice according to their training and expertise, even if both fly in the face of the evidence?

6. We promote evidence-based practice: integrating individual clinical expertise, the best available evidence from clinical research, and the values and preferences of patients.

So far, I have seen little to convince me that chiropractors care a hoot about the best available evidence and plenty to fear that they supress it, if it does not enhance their business.

7. We are committed to supporting our member national associations through advocacy and sharing best practices for the benefit of patients and society.

Much more likely for the benefit of chiropractors, I suspect.

8. We acknowledge the role of chiropractic care, including the chiropractic adjustment, to enhance function, improve mobility, relieve pain and optimize wellbeing.

Of course, you have to pretend that chiropractic adjustments (of subluxations) are useful. However, evidence would be better than pretence.

9. We support research that investigates the methods, mechanisms, and outcomes of chiropractic care for the benefit of patients, and the translation of research outcomes into clinical practice.

And if it turns out to be to the detriment of the patient? It seems to me that you seem to know the result of the research before you started it. That does not bode well for its reliability.

10. We believe that chiropractors are important members of a patient’s healthcare team and that interprofessional approaches best facilitate optimum outcomes.

Of course you do believe that. Why don’t you show us some evidence that your belief is true?

11. We believe that chiropractors should be responsible public health advocates to improve the wellbeing of the communities they serve.

Of course you do believe that. But, in fact, many chiropractors are actively undermining the most important public health measure, vaccination.

12. We celebrate individual and professional diversity and equality of opportunity and represent these values throughout our Board and committees.

What you should be celebrating is critical assessment of all chiropractic concepts. This is the only way to make progress and safeguard the interests of the patient.

13. We believe that patients have a fundamental right to ethical, professional care and the protection of enforceable regulation in upholding good conduct and practice.

The truth is that many chiropractors violate medical ethics on a daily basis, for instance, by not obtaining fully informed consent.

14. We serve the global profession by promoting collaboration between and amongst organizations and individuals who support the vision, mission, values and objectives of the WFC.

Yes, those who support your vision, mission, values and objectives are your friends; those who dare criticising them are your enemies. It seems far from you to realise that criticism generates progress, perhaps not for the WFC, but for the patient.

15. We support high standards of chiropractic education that empower graduates to serve their patients and communities as high value, trusted health professionals.

For instance, by educating students to become anti-vaxxers or by teaching them obsolete concepts such as adjustment of subluxation?

16. We believe in nurturing, supporting, mentoring and empowering students and early career chiropractors.

You are surpassing yourself in the formulation of platitudes.

17. We are committed to the delivery of congresses and events that inspire, challenge, educate, inform and grow the profession through respectful discourse and positive professional development.

You are surpassing yourself in the formulation of platitudes.

18. We believe in continuously improving our understanding of the biomechanical, neurophysiological, psychosocial and general health effects of chiropractic care.

Even if there are no health effects?!?

19. We advocate for public statements and claims of effectiveness for chiropractic care that are honest, legal, decent and truthful.

Advocating claims of effectiveness in the absence of proof of effectiveness is neither honest, legal, decent or truthful, in my view.

20. We commit to an EPIC future for chiropractic: evidence-based, people-centered, interprofessional and collaborative.

And what do you propose to do with the increasing mountain of evidence suggesting that your spinal adjustments are not evidence-based as well as harmful to the health and wallets of your patients?


What do I take out of all this? Not a lot!

Perhaps mainly this: the WFC is correct when stating that, in the interests of the profession in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions. What is missing here is a small but important addition to the sentence: in the interests of the profession and against the interest of patients, consumers or public health in over 90 countries worldwide, the WFC has advocated, defended and promoted the profession across its 7 world regions.

Controlled clinical trials are methods for testing whether a treatment works better than whatever the control group is treated with (placebo, a standard therapy, or nothing at all). In order to minimise bias, they ought to be randomised. This means that the allocation of patients to the experimental and the control group must not be by choice but by chance. In the simplest case, a coin might be thrown – heads would signal one, tails the other group.

In so-called alternative medicine (SCAM) where preferences and expectations tend to be powerful, randomisation is particularly important. Without randomisation, the preference of patients for one or the other group would have considerable influence on the result. An ineffective therapy might thus appear to be effective in a biased study. The randomised clinical trial (RCT) is therefore seen as a ‘gold standard’ test of effectiveness, and most researchers of SCAM have realised that they ought to produce such evidence, if they want to be taken seriously.

But, knowingly or not, they often fool the system. There are many ways to conduct RCTs that are only seemingly rigorous but, in fact, are mere tricks to make an ineffective SCAM look effective. On this blog, I have often mentioned the A+B versus B study design which can achieve exactly that. Today, I want to discuss another way in which SCAM researchers can fool us (and even themselves) with seemingly rigorous studies: the de-randomised clinical trial (dRCT).

The trick is to use random allocation to the two study groups as described above; this means the researcher can proudly and honestly present his study as an RCT with all the kudos these three letters seem to afford. And subsequent to this randomisation process, the SCAM researcher simply de-randomises the two groups.

To understand how this is done, we need first to be clear about the purpose of randomisation. If done well, it generates two groups of patients that are similar in all factors that might impact on the results of the study. Perhaps the most obvious factor is disease severity; one could easily use other methods to make sure that both groups of an RCT are equally severely ill. But there are many other factors which we cannot always quantify or even know about. By using randomisation, we make sure that there is an similar distribution of ALL of them in the two study groups, even those factors we are not even aware of.

De-randomisation is thus a process whereby the two previously similar groups are made to differ in terms of any factor that impacts on the results of the trial. In SCAM, this is often surprisingly simple.

Let’s use a concrete example. For our study of spiritual healing, the 5 healers had opted during the planning period of the study to treat both the experimental group and the control group. In the experimental group, they wanted to use their full healing power, while in the control group they would not employ it (switch it off, so to speak). It was clear to me that this was likely to lead to de-randomisation: the healers would have (inadvertently or deliberately) behaved differently towards the two groups of patients. Before and during the therapy, they would have raised the expectation of the verum group (via verbal and non-verbal communication), while sending out the opposite signals to the control group. Thus the two previously equal groups would have become unequal in terms of their expectation. And who can deny that expectation is a major determinant of the outcome? Or who can deny that experienced clinicians can manipulate their patients’ expectation?

For our healing study, we therefore chose a different design and did all we could to keep the two groups comparable. Its findings thus turned out to show that healing is not more effective than placebo (It was concluded that a specific effect of face-to-face or distant healing on chronic pain could not be demonstrated over eight treatment sessions in these patients.). Had we not taken these precautions, I am sure the results would have been very different.

In RCTs of some SCAMs, this de-randomisation is difficult to avoid. Think of acupuncture, for instance. Even when using sham needles that do not penetrate the skin, the therapist is aware of the group allocation. Hoping to prove that his beloved acupuncture can be proven to work, acupuncturists will almost automatically de-randomise their patients before and during the therapy in the way described above. This is, I think, the main reason why some of the acupuncture RCTs using non-penetrating sham devices or similar sham-acupuncture methods suggest that acupuncture is more than a placebo therapy. Similar arguments also apply to many other SCAMs, including for instance chiropractic.

There are several ways of minimising this de-randomisation phenomenon. But the only sure way to avoid this de-randomisation is to blind not just the patient but also the therapists (and to check whether both remained blind throughout the study). And that is often not possible or exceedingly difficult in trials of SCAM. Therefore, I suggest we should always keep de-randomisation in mind. Whenever we are confronted with an RCT that suggest a result that is less than plausible, de-randomisation might be a possible explanation.


Autologous whole blood (AWB) therapy is a treatment where a patients blood is first drawn from a vein and then (unmodified or treated in various bizarre ways) reinjected intra-muscularly. This sounds barmy, not least because there is no remotely plausible mode of action. Nonetheless, the therapy is popular in some countries (like Germany, where it is practised by many doctors and Heilpraktikers) and recommended for all sorts of illnesses, particularly for strengthening the immune system and fend off infections.

I have personally used it quite a bit and even conducted the first but very small double-blind, placebo-controlled RCT of AWB therapy which showed promising results. Now two systematic reviews of AWB therapy have become available almost simultaneously.

The first systematic review included our plus 7 more clinical studies. The authors included all prospective controlled trials concerning intra-muscular AWB therapy with the exception of trials using oxygenated, UV radiated or heated blood. Information was extracted on the indication, design, additions to AWB and outcome. Full texts were screened for information about the effector mechanisms.

Eight trials met their inclusion criteria. In three controlled trials with patients suffering from atopic dermatitis and urticaria, AWB therapy showed beneficial effects. In five randomized controlled trials (RCTs), two of which concerned respiratory tract infections, two urticaria and one ankylosing spondylitis, no efficacy could be found. A quantitative assessment was not possible due to the heterogeneity of the included studies. The authors found only 4 controlled trials with sample sizes bigger than 37 individuals per group. Only one study investigated the effector mechanisms of AWB.

The German authors concluded that there is some evidence for efficacy of AWB therapy in urticaria patients and patients with atopic eczema. Firm conclusions can, however, not be drawn. We see a great need for further RCTs with adequate sample sizes and for investigation of the effector mechanisms of AWB therapy.

The second systematic review had a slightly different focus in that it assessed AWB therapy as well as autologous serum therapy (AST) for patients suffering from chronic spontaneous urticaria (CSU). Its authors managed to include 8 clinical trials. AST was not more effective than the placebo treatment in alleviating CSU symptoms at the end of treatment (p = .161), and AWB injection was also not more effective in response rates than the placebo at the end of follow-up (p = .099). Furthermore, the efficacy of AST or AWB injection for CSU and the ASST status were not significantly related. No remarkable adverse events were recorded during therapy.

The Taiwanese authors concluded that their meta-analysis suggested that AWB therapy and AST are not significantly more effective in alleviating CSU symptoms than the placebo treatment.

These somewhat contradictory conclusions will confuse most readers. Personally, I think that caution is well-justified. The trials are mostly flawed, and even our positive study (which received the highest possible quality marks by the authors of the first review) can in no way be definitive, because it was far too small for allowing firm conclusions.

Yet, despite all this, I do think that AWB therapy merits further study.


On Twitter, I recently found this remarkable advertisement:

Naturally, it interested me. The implication seemed to be that we can boost our immune system and thus protect ourselves from colds, the flu and other infections by using this supplement. With the flu season approaching, this might be important. On the other hand, the supplement might be unsafe for many other patients. As I had done a bit of research in this area, I needed to know more.

According to the manufacturer’s information sheet, Viracid

  • Provides Support for Immune Challenges
  • Strengthens Immune Function
  • Maintains Normal Inflammatory Balance

The manufacurer furthermore states the following:

Our body’s immune system is a complex and dynamic defense system that comes to our rescue at the first sign of exposure to an outside invader. The dynamic nature of the immune system means that all factors that affect health need to be addressed in order for it to function at peak performance. The immune system is very sensitive to nutrient deficiencies. While vitamin deficiencies can compromise the immune system, consuming immune enhancing nutrients and botanicals can support and strengthen your body’s immune response. Viracid’s synergistic formula significantly boosts immune cell function including antibody response, natural killer (NK) cell activity, thymus hormone secretions, and T-cell activation. Viracid also helps soothe throat irritations and nasal secretions, and maintains normal inflammatory balance by increasing antioxidant levels throughout the body.

This sounds impressive. Viracid could thus play an important role in keeping us healthy. It could also be contra-indicated to lots of patients who suffer from autoimmune and other conditions. In any case, it is worth having a closer look at this dietary supplement. The ingredients of the product include:

  • Vitamin A,
  • Vitamin C,
  • Vitamin B12,
  • Pantothenic Acid,
  • Zinc,
  • L-Lysine Hydrochloride,
  • Echinacea purpurea Extract,
  • Acerola Fruit,
  • Andrographis paniculata,
  • European Elder,
  • Berry Extract,
  • Astragalus membranaceus Root Extract

Next, I conducted several literature searches. Here is what I did NOT find:

  • any clinical trial of Viracid,
  • any indication that its ingredients work synergistically,
  • any proof of Viracid inducing an antibody response,
  • or enhancing natural killer (NK) cell activity,
  • or thymus hormone secretions,
  • or T-cell activation,
  • or soothing throat irritations,
  • or controlling nasal secretions,
  • or maintaining normal inflammatory balance,
  • any mention of contra-indications,
  • any reliable information about the risks of taking Viracid.

There are, of course, two explanations for this void of information. Either I did not search well enough, or the claims that are being made for Viracid by the manufacturer are unsubstantiated and therefore bogus.

Which of the two explanations apply?

Please, someone – preferably the manufacturer – tell me.

I recently saw a tweet by a German homeopath stating that ‘homeopathy is 100% experienced based medicine’. It made me think and realise that there is not just one EBM, there are, in fact, at least three EBMs!

  1. Experience based medicine
  2. Eminence based medicine
  3. Evidence based medicine

I will start with the type which I encountered first when studying medicine all those years ago.


German healthcare was at the time – 1970s – deeply steeped in this variety of EBM. What the professor said was right, and there was no discussion about it. I don’t even know how my teachers would have reacted, if we had challenged their wisdom, because nobody ever did; it just did not occur to us.

Personally, I never got along too well with this type of EBM. I found it stifling, and this feeling might have contributed to my first ‘escape’ to England in 1979. In the UK, I felt, things were refreshingly different (see also my recent obituary of my former boss).


So-called alternative medicine (SCAM) is almost entirely based on this type of EBM. Practitioners of SCAM pride themselves of their experience and are convinced that it outweighs evidence any time. They rarely miss an occasion to stress that their treatment as stood the test of time. And as such it does not require evidence; if SCAM did not work, it would not have survived all these years.

Little do they know that the appeal to tradition is a logical fallacy. And little do they care that the long tradition of their SCAMs might just signal how obsolete their treatments truly are. Hundreds (homeopathy) or thousands (acupuncture) of years ago, we had little knowledge about physiology, pathology, etc., and clinicians had to make do with the little that got. Seen in this light, experience based medicine is a negative label that indicates the fact that the treatments are likely to be obsolete and out-dated.


Providers of SCAM have a deeply rooted dislike for the word evidence. The reason is simple: their SCAMs are usually very shy on evidence; little wonder that they like to focus on experience instead. Yet, try to explain the concept of evidence to someone neutral like a barman, for instance – whenever I made this attempt, I was interrupted by him saying: ‘Hold on, are you saying that before EBM you did not depend on evidence? This is frightening! What on earth did you rely on then?’

It is indeed not logical to rely on eminence or on experience, in my view. And therefore, I have stopped explaining EBM to people who have common sense, like my barman. Let’s try something else instead: imagine you are seriously ill and are able to chose between three clinician who are each the leading head in their type of EMB.


Personally, I would run a mile. I have seen too many of those blundering through the wards of university hospitals. He never makes a mistake, except that things do go wrong quite often; and when they do, it is the fault of some underling, of course.


With a bit of bad luck, he might be a homeopath. He will tell you endlessly of cases that were similar to yours. Occasionally, there was an aggravation (which, of course, is a good sign in his view), but in the end he cured them all with his treatments that had stood the test of time. He has excellent bedside manners, a lot of charisma, and is a good listener. Who was it that said: “the three most dangerous words in medicine are IN MY EXPERIENCE”?

Yes, you guessed it: run and don’t turn back!


He might not be all that charismatic, perhaps he even is a bit abrupt. But he will know the latest developments and weigh the risks of all therapeutic options against their benefits.

But hold on, my barman would interrupt at this point, this is not either or. One can have both experience and evidence!

I told you my barman was clever. The definition of evidence based medicine is not healthcare based on up-to date knowledge, it is the integration of best research evidence with clinical expertise and patient values. It thus rests on three pillars: external evidence, ideally from systematic reviews, the clinician’s experience, and the patient’s preferences.

Therefore, my barman and I agree that eminence based medicine is highly questionable, experience based medicine can be outright dangerous, and evidence based medicine is the only EBM version that does make sense.



Myelopathy is defined as any neurologic deficit related to the spinal cord. When due to trauma, it is known as (acute) spinal cord injury. When caused by inflammatory, it is known as myelitis. Disease that is vascular in nature is known as vascular myelopathy.

The symptoms of myelopathy include:

  • Pain in the neck, arm, leg or lower back
  • Muscle weakness
  • Difficulty with fine motor skills, such as writing or buttoning a shirt
  • Difficulty walking
  • Loss of urinary or bowel control
  • Issues with balance and coordination

The causes of myelopathy include:

  • Tumours that put pressure on the spinal cord
  • Bone spurs
  • A dislocation fracture
  • Autoimmune diseases like multiple sclerosis
  • Congenital abnormality
  • A traumatic injury

This review presents a series of cases with cervical spine injury and myelopathy following therapeutic manipulation of the neck, and examines their clinical course and neurological outcome.

Its authors conducted a search for patients who developed neurological symptoms due to cervical spinal cord injury following neck SMT in the database of a spinal unit in a tertiary hospital between the years 2008 and 2018. Patients with vertebral artery dissections were excluded. Patients were assessed for the clinical course and deterioration, type of manipulation used and subsequent management.

A total of four patients were identified, two men and two women, aged between 32 and 66 years. In three patients neurological deterioration appeared after chiropractic adjustment and in one patient after tuina therapy. The patients had experienced symptoms within one day to one week after neck manipulation. The four patients had signs of:

  1. central cord syndrome,
  2. spastic quadriparesis,
  3. spastic quadriparesis,
  4. radiculopathy and myelomalacia.

Three patients were managed with anterior cervical discectomy and fusion while one patient declined surgical treatment.

The authors note that their data cannot determine whether the spinal cord dysfunction was caused my the spinal manipulations or were pre-existing problems which were aggravated by the treatments. They recommend that assessment for subjective and objective evidence of cervical myelopathy should be performed prior to cervical manipulation, and suspected myelopathic patients should be sent for further workup by a specialist familiar with cervical myelopathy, such as a neurologist, a neurosurgeon or orthopaedic surgeon who specializes in spinal surgery. They also state that manipulation therapy remains an important and generally safe treatment modality for a variety of cervical complaints. Their review, the authors stress, does not intend to discard the role of spinal manipulation as a significant part in the management of patients with neck related symptoms, rather it is meant to draw attention to the need for careful clinical and imaging investigation before treatment. This recommendation might be medically justified, yet one could argue that it is less than practical.

This paper from Israel is interesting in that it discloses possible complications of cervical manipulation. It confirms that chiropractors are most frequently implicated and that – as in our survey – under-reporting is exactly 100% (none of the cases identified by the retrospective chart review had been previously reported).

In light of this, some of the affirmations of the authors are bizarre. In particular, I ask myself how they can claim that cervical manipulation is a ‘generally safe’ treatment. With under-reporting at such high levels, the only thing one can say with certainty is that serious complications do happen and nobody can be sure how frequently they occur.

There is a long-standing debate on the question whether the use of homeopathy saves money. Homeopathy fans usually insist that it does. Even the Smallwood report commissioned by Prince Charles claimed that the NHS could save pots of money, if GPs only used more homeopathy.

And it is true, of course: on average homeopathics are cheaper than drugs. Therefore, replacing drugs with homeopathics would be a cost-saving. But, in healthcare, we cannot think like this; if we did, this logic would tell us that not doing anything at all would be even cheaper.

Somehow, we need to factor into the equation the effectiveness of the interventions that we are evaluating. The way to do this is to conduct proper cost-effectiveness analyses. And the reliable evidence from such assessments fails to confirm the notion that homeopathy might save us money.

So, why did I entitle this post HOW TO SAVE MONEY WITH HOMEOPATHY?

Because, it is true: you can save money, if you adhere to my instructions!

If you or a friend of yours are ill and therefore tempted by the numerous claims of homeopaths, please follow this simple step by step procedure:

  1. Go to your library, find a reliable book (I recommend this one), inform yourself what homeopathy truly is and absorb in the fact that a typical homeopathic remedy contains exactly zero active molecules.
  2. Read a bit further and check out what the best evidence from rigorous clinical trials tells us about the effectiveness of homeopathy.
  3. Go to a pharmacy that specialises in homeopathic products.
  4. Ask the pharmacist which homeopathic remedies she recommends for the ailment you suffer from.
  5. Ask the pharmacist to tell you what these would cost.
  6. Tell the pharmacist what you have just learnt about the evidence.
  7. Ask her kindly not to mislead customers in future.
  8. Go home.
  9. Repeat 3 – 8 as often as you can.

I think you have to agree that by following my instructions, you have saved exactly the amount of money that the pharmacist quoted.




And for those for whom this advice comes too late, because they already have at home a selection of homeopathic remedies, I have the following cost-saving trick: use them for sweetening your tea or coffee. This saves you the cost of buying sugar – every little bit helps!
