The COVID-19 pandemic has posed an unprecedented challenge to global health. Classical homeopathy may, according to homeopaths, have a role to play in alleviating this burden. The objective of this study was to curate data on the treatment effect of classical homeopathy for COVID-19 in a real-world scenario to guide future scientific investigations.
Classical homeopaths from the International Academy of Classical Homeopathy (IACH) were asked to provide details on cases they treated by filling out a standardized questionnaire. COVID-19 cases were defined according to World Health Organization (WHO) criteria as suspected/probable/confirmed cases, with intervention provided being either stand-alone classical homeopathy or combined with conventional therapy for COVID-19. Cases were followed up with main outcomes being ‘improved’, ‘not improved’, or ‘progressed’ post-treatment. Details of the homeopathic remedies used and the main symptoms at the presentation were gathered. Factors associated with main outcomes were investigated with correlational and regression analyses.
367 patients (male 166, female 201) met eligibility criteria (mean age 42.75 years). The mean follow-up period was 6.5 (standard deviation, SD=5.3) days. 255 were confirmed COVID-19 cases, with 61 probable and 51 suspected cases, respectively. The most used remedy was Arsenicum album. Over 73% of COVID-19 patients (and about 79% of severe cases) improved under classical homeopathic treatment. The number of remedies required per individual was negatively correlated to improvement (P< 0.01). Fever, the most common symptom at presentation (74.4%), was associated with an increased likelihood of improvement (P<0.01). Improvement was negatively associated with advanced age, but not associated with sex (P<0.01).
The authors conclude that this study suggests that classical homeopathy was associated with improvement in COVID-19, including severe cases. Despite limitations from study design and data sources, our findings should prompt further studies on the role of classical homeopathy in the management of COVID-19.
I BEG TO DIFFER!
These cases suggest nothing of the sort. If anything, these highly selected cases suggest that about 27% of the exemplary patients did not improve, perhaps they even died. This implies to me that classical homeopathy worsens the prognosis of patients infected with COVID-19.
The ‘International Academy of Classical Homeopathy‘ is led by the ‘Ueber-Homeopath’, George Vithoulkas. His vision is that this Academy will become a center of real knowledge which will provide an education that will far exceed the technical and strictly “medical” aspect of one’s learning. One might ask what fanatics like he truly want to achieve – is it perhaps the promotion of ‘euthanasia homoeopathica’?
This survey evaluated the attitude of healthcare professionals toward the use of so-called alternative medicine (SCAM) to improve current care. A questionnaire on the current practice and opinions about SCAM use was sent to healthcare professionals in Amsterdam UMC, who work for the department of hematology or oncology. Oncologists, hematologists, residents, (specialized) nurses, dieticians, (hospital)pharmacists, and pharmacy technicians were asked to participate.
Among eligible healthcare professionals, 77 responded to the questionnaire (34%). Overall, 87% of healthcare
professionals indicated it is important to be aware of their patient’s SCAM use, and all find the potential of drug–herb interactions important. However, more than half of the healthcare professionals inquire about the patient’s SCAM use infrequently. In addition, only 15% of the healthcare professionals stated they had sufficient knowledge of SCAM to advise patients on their use of SCAM.
The authors concluded that healthcare professionals are aware of the potential risks of SCAM use in combination with anti-cancer treatment. However, SCAM use is not yet discussed with every patient. This may be due to healthcare professionals’ lack of knowledge about SCAM.
This survey would in itself be fairly irrelevant; it employed only a tiny convenience sample and its findings cannot be generalized. Yet, it produced results that have been shown dozens of times before, and it might therefore be a good idea to remind ourselves of their relevance and implications.
- Patients use SCAM whether we want it or not.
- Contrary to what is often said, SCAM is not harmless.
- Therefore conventional healthcare professionals need to know about their patients’ SCAM use.
- To find out, healthcare professionals need to ask specific questions about SCAM.
- Next, they must advise their patients responsibly (this is an ethical obligation, not a choice).
- In order to do that they need to learn the essentials about SCAM.
- Failing to do this means failing their patients.
The General Chiropractic Council (GCC) “regulates chiropractors in the UK to ensure the safety of patients undergoing chiropractic treatment”. One might have assumed that they thus fulfill the important role of controlling the profession. Yet, one would have assumed wrongly. Instead of controlling, the GCC usually prefers promoting the profession. Their recent Chiropractic Patient Satisfaction and Experience is a good example. Let me show you several important sections of this document:
The outcomes reported here highlight two key findings:
• Overwhelmingly, chiropractic patients report high levels of satisfaction and positive experiences with their care. This was true both in the literature that examined international patient cohorts as well as the specific data collected from UK based chiropractic patients.
• A strong therapeutic relationship and good communication between patient and chiropractor underpins high satisfaction scores and a positive experience. This was confirmed both in the international literature and through both quantitative and qualitative analysis of specific data collected from UK based chiropractic patients.
Conclusion
This report shows that both existing literature and de novo data collection from patients receiving chiropractic care in the UK highlight excellent perceived experience and high satisfaction with such care.
Factors such as therapeutic alliance and communication are strongly associated with these positive perceptions by patients although other factors such as treatment beliefs were also significantly associated with satisfaction scores.
Recommendations
• To offer the highest quality of care, both in terms of clinical outcomes and patient experience, chiropractors should be explicitly skilled at curating excellent therapeutic alliances and communication with patients.
• Such skills and competences within chiropractic care delivery should receive higher visibility within the chiropractic profession generally and more specifically through advocacy within leading institutions and core emphasis within chiropractic curricula.

By changing a few words, I have adapted the above excerpts to become a Customer Satisfaction and Experience Report of a fictitious hamburger joint published by the Hamburger General Council (HGC) of Great Britain which regulates hamburger joints in the UK to ensure the safety of consumers undergoing hamburger nutrition:
The outcomes reported here highlight two key findings:
• Overwhelmingly, customers report high levels of satisfaction and positive experiences with their restaurant. This was true both in the literature that examined international consumer cohorts as well as the specific data collected from UK based customers.
• A strong professional relationship and good communication between customer and service personell underpins high satisfaction scores and a positive experience. This was confirmed both in the international literature and through both quantitative and qualitative analysis of specific data collected from UK based hamburger consumers.
Conclusion
This report shows that both existing literature and de novo data collection from consumers eating hamburgers in the UK highlight excellent perceived experience and high satisfaction with such service.
Factors such as personal alliance and communication are strongly associated with these positive perceptions by consumers although other factors such as appetite were also significantly associated with satisfaction scores.
Recommendations
• To offer the highest quality of service, both in terms of profit and patient experience, hamburger vendors should be explicitly skilled at curating excellent professional alliances and communication with customers.
• Such skills and competences within hamburger delivery should receive higher visibility within the gastronomic trade generally and more specifically through advocacy within leading institutions and core emphasis within servers’ curricula.

If you get the impression that I am taking the Mickey of the GCC, you are not mistaken. Yet, this post also has slightly more serious purposes. I wanted to 1) show how, in the chiropractic profession, pure BS is often disguised as research, and 2) question whether the GCC is fit for purpose.
On a more constructive note: there are many open questions that urgently need addressing in the realm of chiropractic (e.g. do chiropractors more good than harm?). I, therefore, suggest that the GCC stops publishing idiotic promotional documents disguised as research and gets on with its responsibilities.
I have to admit that I do not regularly read the DMZ, a German paper. In fact, until a minute ago, I did not know it existed. Nor do I know Anton Aeberhard. I saw his DMZ homeopathy article on the Internet and find it excellent; so much so that I translated parts of it for you:
… Because this pseudoscience is considered by some people to be an effective alternative to conventional medicine, it is important to understand the potential dangers and risks of homeopathy…
Homeopathy is based on the principle of the rule of similars and extreme dilution of substances. However, there is no scientific evidence that homeopathic remedies have any therapeutic effect beyond the placebo effect. Most studies that purport to show efficacy are methodologically flawed. Homeopathy contradicts fundamental principles of biology, chemistry, and physics. It is therefore irresponsible to consider this practice a legitimate medical treatment.
One of the greatest and real dangers of homeopathy is that it can cause people to refuse or delay effective medical treatments. By believing in homeopathic remedies, life-threatening conditions such as cancer, heart disease, or infections may not be treated appropriately. This can lead to worsening health conditions and increase the risk of complications or even death…
Conclusion I
Homeopathy is a pseudoscientific practice based on outdated principles and a lack of scientific evidence. The dangers of this practice should not be underestimated. It can cause people to reject or delay effective medical treatments, which can endanger their health and lives. It is important to make informed decisions about health care and to rely on evidence-based medicine to provide the best possible treatment and care.
Conclusion II.
Homeopathy is a joke.

Thank you Anton Aeberhard!
It is not often that we find a journalist who has the courage to defy the demand for ‘balance’. In the case of clear nonsensical issues, this demand becomes a demand for misleading people, a demand for FALSE balance!
When a journalist writes about the planet, he does not require a representative of the FLAT EARTH SOCIETY to add his views. Similarly, when someone writes about homeopathy, there is no need to interview the chair of a homeopaths’ association saying: “But we have 200 years of experience and we therefore know it works…”
Lumbosacral Radicular Syndrome (LSRS) is a condition characterized by pain radiating in one or more dermatomes (Radicular Pain) and/or the presence of neurological impairments (Radiculopathy). So far, different reviews have investigated the effect of HVLA (high-velocity low-amplitude) spinal manipulations in LSRS. However, these studies included ‘mixed’ population samples (LBP patients with or without LSRS) and treatments other than HVLA spinal manipulations (e.g., mobilisation, soft tissue treatment, etc.). Hence, the efficacy of HVLAT in LSRS is yet to be fully understood.
This review investigated the effect and safety of HVLATs on pain, levels of disability, and health-related quality of life in LSRS, as well as any possible adverse events.
Randomized clinical trials (RCTs) published in English in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (PubMed), EMBASE, PEDro, and Web of Science were identified. RCTs on an adult population (18-65 years) with LSRS that compared HVLATs with other non-surgical treatments, sham spinal manipulation, or no intervention were considered. Two authors selected the studies, extracted the data, and assessed the methodological quality through the ‘Risk of Bias (RoB) Tool 2.0’ and the certainty of the evidence through the ‘GRADE tool’. A meta-analysis was performed to quantify the effect of HVLA on pain levels.
A total of 308 records were retrieved from the search strings. Only two studies met the inclusion criteria. Both studies were at high RoB. Two meta-analyses were performed for low back and leg pain levels. HVLA seemed to reduce the levels of low back (MD = -1.48; 95% CI = -2.45, -0.50) and lower limb (MD = -2.36; 95% CI = -3.28, -1.44) pain compared to other conservative treatments, at three months after treatment. However, high heterogeneity was found (I² = 0.0%, p = 0.735). Besides, their certainty of the evidence was ‘very low’. No adverse events were reported.
The authors stated that they cannot conclude whether HVLA spinal manipulations can be helpful for the treatment of LSRS or not. Future high-quality RCTs are needed to establish the actual effect of HVLA manipulation in this disease with adequate sample size and LSRS definition.
Chiropractors earn their living by applying HVLA thrusts to patients suffering from LSRS. One would therefore have assumed that the question of efficacy has been extensively researched and conclusively answered. It seems that one would have assumed wrongly!
Now that this is (yet again) in the open, I wonder whether chiropractors will, in the future, tell their patients while obtaining informed consent: “I plan to give you a treatment for which sound evidence is not available; it can also cause harm; and, of course, it will cost you – I hope you don’t mind.”
Numerous qualitative studies and a few quantitative studies have linked vaccine hesitancy or refusal with the belief in the efficacy of so-called alternative medicine (SCAM). Yet, large-scale data on this topic are scarce. In this study, the French researchers investigated the factors associated with the coverage rates of seven childhood vaccines or vaccine groups in the ninety-six metropolitan French departments. One of the factors investigated was the local interest in SCAM. In order to assess this interest, they built an Alternative Medicine Index based on departmental internet searches regarding SCAM—internet searches being a reliable indicator of the public’s actual interest in a given topic. They then conducted multiple regression analyses, which showed that this Index is a significant explanatory factor for the departmental variance in vaccination coverage rates, exceeding in importance the effect of other relevant local sociodemographic factors.
A further recent study from France adds to the picture. It presents the results of a survey conducted in July 2021 among a representative sample of the French mainland adult population (n = 3087). Using cluster analysis, the researchers identified five profiles of SCAM attitudes and found that even among the most pro-SCAM group, very few respondents disagreed with the idea that SCAM should only be used as a complement to conventional medicine. They then compared these SCAM attitudes to vaccine attitudes. Attitudes to SCAM had a distinct impact as well as a combined effect on attitudes to different vaccines and vaccines in general. They found that:
- attitudes to SCAM provide a very limited explanation of vaccine hesitancy;
- among the hesitant, pro-SCAM attitudes are often combined with other traits associated with vaccine hesitancy such as distrust of health agencies, radical political preferences, and low income.
Both SCAM endorsement and vaccine hesitancy are more prevalent among the socially disadvantaged. Drawing on these results, the researchers argue that, to better understand the relationship between SCAM and vaccine hesitancy, it is necessary to look at how both can reflect a lack of access and recourse to mainstream medicine and distrust of public institutions.
The fact that the enthusiasm for SCAM is associated with vaccine hesitancy has been discussed on this blog many times before, e.g.:
- Preference of so-called alternative medicine predicts negative attitudes to vaccination
- What are the reasons for opposing COVID vaccinations?
- Intelligence, Religiosity, SCAM, Vaccination Hesitancy – are there links?
- More information on homeopaths’ and anthroposophic doctors’ attitude towards vaccinations
- The anti-vaccination movement is financed by the dietary supplement industry
- Sorry, I was wrong about homeopathy and vaccination
- The UK Society of Homeopaths, a hub of anti-vaccination activists?
- HOMEOPATHY = “the complete alternative to vaccination” ?!?!
- Are anthroposophy-enthusiasts for or against vaccinations?
- Far too many chiropractors believe that vaccinations do not have a positive effect on public health
- Naturopaths’ counselling against vaccinations could be criminally negligent
- HOMEOPATHS AGAINST VACCINATION: “The decision to vaccinate and how you implement that decision is yours and yours alone”
- Use of alternative medicine is associated with low vaccination rates
- Integrative medicine physicians tend to harbour anti-vaccination views
- Vaccination: chiropractors “espouse views which aren’t evidence based”
What seems fairly clear to me is that a cross-correlation exists: an attitude against modern medicine and the ‘scientific establishment’ determines both the enthusiasm for SCAM and the aversion to vaccination. What is, however, far from clear to me is what we could do about it.
Yes, better education seems important – and that’s precisely what I aim at achieving with this blog. Sadly, judging from some of the comments we receive, it does not seem crowned with much success.
Any other ideas?
“The decline of homeopathy, the ‘medicine’ that doesn’t cure anything” is the title of a remarkable article in EL PAIS of which I take the liberty of showing you a few key passages:
In the more than 200 years that have passed since its invention, no one has been able to prove that homeopathy is actually capable of curing anything with its alleged medicines that have no active ingredients…
…EL PAÍS reached out to some of its main promoters, such as the pharmaceutical company Boiron, leader in the sector; the Spanish Association of Homeopathy Pharmacists and the Spanish Society of Homeopathic Doctors. In the absence of a response from all three, the explanations are given by experts who are more critical of the discipline.
Many people who used to consume homeopathy were not even aware that this was the case. Fernando Frías, one of the activists who worked to undermine the discipline’s remaining prestige, recalls that people did not believe them when they were told that compounds with diluted Berlin Wall were sold to overcome the feelings of oppression and anxiety. This was actually commercialized under the premise that “like cures like”: if the Berlin Wall oppressed, a piece of it diluted in water should remedy it. “Many were under the impression that it was just a natural therapy and that we were making things up to attack it,” says Frías…
… There has been a lot of debate about how to regulate an alleged drug whose only effect is, in truth, the placebo effect. In 2001, the European Parliament issued a directive that covered its use in countries with a homeopathic tradition; sources explain that this happened due to the pressure exerted by both the industries and the governments of countries where pseudoscience is deep-rooted, such as France (where Boiron is headquartered) or Germany, where its consumption is much higher than in others, such as Spain.
“Having regard to the particular characteristics of these homeopathic medicinal products, such as the very low level of active principles they contain and the difficulty of applying to them the conventional statistical methods relating to clinical trials, it is desirable to provide a special, simplified registration procedure for those homeopathic medicinal products which are placed on the market without therapeutic indications in a pharmaceutical form and dosage which do not present a risk for the patient,” states the directive.
In its more than two centuries of history, this is not the first time that homeopathy loses ground. Still, Frías warns, it cannot be ruled out that at some point something will come up that will make it fashionable again. “Look at the example of chemtrails [the condensation trails left by airplanes that some conspiracy theorists believe are a way of poisoning the population from the air]. It seemed that no one remembered them anymore, but now they’re back,” he says. Frías cites the astrophysicist and disseminator Javier Armentia, who states that beliefs are like a rubber duck: no matter how much they sink, they always resurface. “Especially if there is money behind,” he adds.

As reported previously, homeopathy and other forms of so-called alternative medicine (SCAM) have come under fire in Spain. In 2017, ‘HOMEOPATHY PLUS‘ reported that “in a reversal of the 2015 Royal Legislative Decree, the Minister of Health has withdrawn homeopathic remedies and outlawed the practice in Spain’s national health services.” In 2018, more than 400 people signed an open letter triggered by the case of a cancer patient who died after preferring homeopathy to regular treatment. “Let’s be clear: pseudoscience kills,” begins the letter. Since then, the struggle of Spanish rational thinkers to stop misleading information about SCAM in general and homeopathy, in particular, has only intensified.
Spain is thus joining other European countries in opposing misinformation about homeopathy. Contrary to what some have claimed (for instance, in the comments section of this blog), most of the opponents do not want to restrict the public’s choice. People who wish to use homeopathy should be able to do so (but should pay for it themselves). However, the choice must be based on evidence-based information.
Semen retention is a so-called alternative medicine (SCAM) that involves intentionally avoiding ejaculating. A person can do this by abstaining from any sexual activity, stopping before the point of ejaculation, or teaching themselves to orgasm without ejaculating.
Although this practice may seem new, this is likely only due to recent internet popularity. In fact, semen retention is an ancient practice, believed to boost male physical and spiritual energy.
Some other names for semen retention include:
- coitus reservatus
- seminal conservation
- sexual continence
It is also known as or included in practices called:
- karezza (Italian)
- maithuna (Hindu Tantra)
- sahaja (Hindu Yoga)
- tantra (Hinduism and Buddhism)
- cai Yin pu Yang and cai Yang pu Yin (Taoist)
Semen retention is said to be good for a range of things:
Mental health
- increased motivation
- improved energy and focus
- more self-confidence
- reduced anxiety
- better memory
- improved concentration
Physical health
- clearer skin
- increased testosterone
- more weight loss
- increased muscle mass
- physical rejuvenation
- a deeper voice
Spiritual health
- a greater sense of purpose
- stronger or deeper emotional bonds in relationships
- a stronger sense of overall harmony

Yes, I agree, this sounds weird!
But is there any evidence?
Yes, e.g.:
Males of some species use mate retention behavior and investment in ejaculate quality as anti-cuckoldry tactics concurrently while others do so in a compensatory fashion. Leivers, Rhodes, and Simmons (2014) reported that men who performed mate retention less frequently produced higher-quality ejaculates, suggesting that humans use these tactics compensatorily. We conducted a conceptual replication of this research in a sample of 41 men (18-33 years; M = 23.33; SD = 3.60). By self-report, participants had not had a vasectomy and had never sought infertility treatment. We controlled for several covariates known to affect ejaculate quality (e.g., abstinence duration before providing an ejaculate) and found no statistically significant relationships between mate retention behavior and four components of ejaculate quality: sperm velocity, sperm concentration, slow motility, and ejaculate volume. The present results provide little support for the hypothesis that human males deploy mate retention behavior and ejaculate quality investment compensatorily. We discuss the limitations of this study and highlight the need for research to address questions about the nature of anti-cuckoldry tactic deployment in humans, especially concerning investment in ejaculate quality.
In species where females mate with multiple males, the sperm from these males must compete to fertilise available ova. Sexual selection from sperm competition is expected to favor opposing adaptations in males that function either in the avoidance of sperm competition (by guarding females from rival males) or in the engagement in sperm competition (by increased expenditure on the ejaculate). The extent to which males may adjust the relative use of these opposing tactics has been relatively neglected. Where males can successfully avoid sperm competition from rivals, one might expect a decrease in their expenditure on tactics for the engagement in sperm competition and vice versa. In this study, we examine the relationship between mate guarding and ejaculate quality using humans as an empirical model. We found that men who performed fewer mate guarding behaviors produced higher quality ejaculates, having a greater concentration of sperm, a higher percentage of motile sperm and sperm that swam faster and less erratically. These effects were found independent of lifestyle factors or factors related to male quality. Our findings suggest that male expenditure on mate guarding and on the ejaculate may represent alternative routes to paternity assurance in humans.
The uncritical application of western psychiatric concepts in non-western societies resulting in culturally invalid psychiatric syndromes, have been extensively documented. Such instances are considered ‘category errors’. In contrast, ‘reverse category errors’ although theoretically postulated, have never been empirically demonstrated. Diagnostic criteria of an established South Asian culture specific neurosis, Dhāt syndrome, were deployed by a psychiatrist of South Asian origin, amongst 47 white Britons in London, UK, presenting for the first time with a clinic diagnosis of ICD-9 Depressive Neurosis (Dysthymic Disroder, ICD-11). The proceedure yielded a new disorder, Semen Retention Syndrome. Based on narrative accounts and quantitative scores on the Hamilton Depression Rating Scale, the evidence suggests that a significant subset of white British subjects diagnosed with Dysthymic Disorder, may in fact be expressing a psychological variation of a previously unknown local White British somatisation phenomena labelled Semen Retention Syndrome. Anxiety and depressive symptoms presented by this subset of subjects were primarily attributed to a core irrational belief and a cognitive error centered around misunderstood concepts of semen physiology. Consequently, the undue focus on mood idioms by both white British patients and their health professionals, leads to a mistaken diagnosis of Mood Disorder, and results in incorrect treatment. The implications of this ethnocentric mode of reasoning raises concerns about existing concepts in psychiatric phenomenology and for official international diagnostic classificatory systems. The paper concludes by arguing that category errors in both directions are instances of cultural iatrogenesis, and underscore the importance of a culturally valid psychiatry.

I was unable to find support for any of the above-listed effects of semen retention. So, claims like “Semen Retention is life-changing, especially for men. Not only, it help you turn into a real alpha male but also offers great health benefits” need to be taken with a pinch of salt. Yet, it did occur to me that semen retention might have one positive outcome:
It reduces the chances of stupid people multiplying!
It has been reported, at the German Medical Congress (DÄT) a year ago, that it was decided to delete the additional title of homeopathy from the model further training regulations of the German Medical Association. And Federal Health Minister Karl Lauterbach (SPD) tweeted applause: “Homeopathy has no place in modern medicine.”
Now the ‘ Bundesverband der Pharmaziestudierenden in Deutschland’ (BPhD), the German Pharmacists Organization, even goes a few steps further. The position paper distinguishes between evidence-based medicine (EBM) and unproven therapeutic methods. According to the BPhD, these include homeopathy, but also anthroposophy, traditional Chinese medicine, and traditional medicines.
Among other things, the BPhD is disturbed by the way homeopathy presents itself as an alternative, because an alternative means “a choice between two equally suitable possibilities” to achieve a goal, and this is not the case. Compared to evidence-based medicine (EBM), homeopathy is a “constructed, illusory concept” and “the principles of homeopathic teachings and principles” are to be rejected as “unscientific”. According to the BPhD, a designation as “alternative” for advertising purposes should no longer be allowed.
They would also like to see a demarcation from naturopathy; the clear distinction between homeopathy and phytopharmacy has been lacking up to now. The advertising attribute “natural” should therefore also be banned in order to prevent equalization in advertising, the position paper states.
Like doctors, pharmacy students point to the lack of proof of efficacy beyond the placebo effect. According to the BPhD, the dogma WER HEILT HAT RECHT, “he who heals is right” would “disregard all processes that work towards healing and glorify the result”. The “gold standard” of EBM – randomized, double-blind studies with placebo control – should in future also have to be fulfilled by homeopathic medicines, experience reports are not sufficient, it continues.
Homeopathic medicines are only registered as medicinal products without indication, which requires neither proof of efficacy nor clinical studies. The BPhD, therefore, demands that a warning be placed on the preparations that they have “no proven efficacy beyond the placebo effect”. Up to now, without this warning, patients have been “deceived about the efficacy”, and there is an “urgent need for detailed public information and counseling on homeopathy since its unjustified reputation poses a danger of not seeking treatment”. The BPhD also demands that the status of homeopathic medicines is withdrawn and that the pharmacy obligation for the preparations is abolished…
“In the health professions, no trivialization of unproven therapeutic procedures should be tolerated, as inadequate counseling or ignorance poses a danger to patients,” the BPhD said.

When I first read this article – I translated and shortened it for those who cannot read German- I was truly dazzled. These are the suggestions that I have been making for around 20 years now, not specifically for Germany but for pharmacists in general. For many years, the Germans seemed the least likely to agree with me. But now they seem to be ahead of everyone else in Europe!
How come?
I suspect and hope that our recent initiative might have something to do with it.
Let’s hope that the pharmacists of other countries follow the German example.
A team of French researchers assessed whether a conflict of interest (COI) might be associated with the direction of the results of meta-analyses of homoeopathy trials. Their analysis (published as a ‘letter to the editor) is complex, therefore, I present here only their main finding.
The team conducted a literature search until July 2022 on PubMed and Embase to identify meta-analyses of randomized clinical trials assessing the efficacy of homoeopathy. They then assessed the existence of potential COI, defined by the presence of at least one of the following criteria:
- affiliation of one or more authors to an academic homoeopathy research or care facility, or to the homoeopathy industry;
- research sponsored or funded by the homoeopathy industry;
- COI declared by the authors.
The researchers also evaluated and classified any spin in meta-analyses conclusions into three categories (misleading reporting, misleading interpretation and inappropriate extrapolation). Two reviewers assessed the quality of meta-analyses and the risk of bias based. Publication bias was evaluated by the funnel plot method. For all the studies included in these meta-analyses, the researchers checked whether they reported a statistically significant result in favour of homoeopathy. Further details about the methods are provided on OSF (https://osf.io/nqw7r/) and in the preregistered protocol (CRD42020206242).
Twenty meta-analyses were included in the analysis (list of references available at https://osf.io/nqw7r/).
- Among the 13 meta-analyses with COI, a significantly positive effect of homoeopathy emerged (OR=0.60 (95% CI 0.50 to 0.70)).
- There was no such effect for meta-analyses without COI (OR=0.96 (95% CI 0.75 to 1.23)).
The authors concluded that in the presence of COI, meta-analyses of homoeopathy trials are more likely
to have favourable results. This is consistent with recent research suggesting that systematic reviews with financial COI are associated with more positive outcomes.
Meta-analyses are systematic reviews (critical assessments of the totality of the available evidence) where the data from the included studies are pooled. For a range of reasons, this may not always be possible. Therefore the number of meta-analyses (20) is substantially lower than that of the existing systematic reviews (>50).
Both systematic reviews and meta-analyses are theoretically the most reliable evidence regarding the value of any intervention. I said ‘theoretically’ because, like any human endeavour, they need to be done in an unbiased fashion to produce reliable results. People with a conflict of interest by definition struggle to be free of bias. As we have seen many times, this would include homoeopaths.
This new analysis confirms what many of us have feared. If proponents of homeopathy with an overt conflict of interest conduct a meta-analysis of studies of homeopathy, the results tend to be more positive than when independent researchers do it. The question that emerges from this is the following:
Are the findings of those researchers who have an interest in producing a positive result closer to the truth than the findings of researchers who have no such conflict?
I let you decide.
