homeopathy
So-called alternative medicine (SCAM) likes to present itself as a champion of disease prevention. Its advocates routinely claim to promote health before disease develops, to strengthen the body’s defences, and to address root causes rather than symptoms. This rhetoric is highly attractive, because prevention sounds proactive, humane, and economical. Crucially, it is also good for the SCAM practitioner’s bank account. Yet there is a snag: almost none of the preventive claims made for SCAM are supported by reliable evidence, whereas the prevention that works comes overwhelmingly from conventional medicine and science.
To show preventive benefit, an intervention must demonstrably reduce the incidence of symptom, disease, complication, or mortality in properly designed studies. That may require randomised trials, epidemiological studies, large cohorts, reproducible findings, and enough follow-up to show that fewer people actually experienced the given endpoint. Mainstream medicine has repeatedly met this standard. Immunization, blood pressure control, smoking cessation, lipid lowering, cancer screening, and risk-factor modification are all products of biomedical research, not of alternative healing traditions.
SCAM, by contrast, tends to use prevention in a loose, impressionistic, and unfalsifiable way. A practitioner may claim that a treatment “balances energy,” “supports immunity,” or “keeps the body in harmony,” but such phrases do not establish a preventive effect. They are placeholders for evidence, not evidence itself. In practice, the absence of disease after treatment is treated as proof that the treatment worked, even though the same outcome occurs every day without any intervention at all.
Acupuncture is a good example. Its defenders portray it as a preventive system capable of preserving general health or warding off illness, but the evidence base does not support that claim. Some reviews do suggest that acupuncture may help with some pain-related and symptom-focused conditions, yet its preventive value is largely unproven. I am not aware of solid evidence to show that acupuncture prevents anything – but, if I am wrong, please do correct me.
Chiropractic care is even more revealing because preventive claims are often tied to the doctrine of spinal “subluxation” and nervous system dysfunction. Yet the literature on prevention is thin and methodologically weak. I am not aware of solid evidence to show that chiropractic prevents anything – but, if I am wrong, please do correct me.
Herbalism benefits from the romantic appeal of “natural” remedies, but that appeal should not be confused with demonstrated preventive efficacy. Individual plant compounds have certainly inspired real drugs, yet that is a triumph of pharmacology, not of herbalism as a system. When herbal medicines are tested for prevention, results are usually weak, inconsistent, or insufficient to support recommendation. I am not aware of solid evidence to show that herbal medicine prevents anything – but, if I am wrong, please do correct me.
Homeopathy is one of the most extreme cases within SCAM. It is often sold as gentle, individualized, and even preventive, but its basic principles are scientifically implausible, and its clinical evidence is either flawed or negative. Preventive homeopathy, including ideas such as “homeoprophylaxis,” is particularly problematic because it can give people a false sense of security while displacing interventions that genuinely prevent disease, such as vaccination. I am not aware of solid evidence to show that homeopathy prevents anything – but, if I am wrong, please do correct me.
SCAM speaks almost constantly about prevention, but the evidence for actual preventive benefit is close to non-existent. What we know about prevention, what truly reduces disease incidence and improves population health, comes from conventional medicine, epidemiology, public health, and biological science. SCAM will no doubt continue to borrow the language of medicine and prevention, but – as far as I can see – it has failed to supply the proof.
During outbreaks of Ebola Virus Disease (EVD), public health organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) combat “infodemics”, i.e. surges of false information and unproven so-called alternative medicine (SCAM) polluting social media (Bedrosian et al., 2016; Fung et al., 2016; Obol & Nzedibe, 2024). Because these SCAMs are ineffective and frequently dangerous, authorities issue warnings against their use. Here are just a few of the many claims that can be found:
- Bathing in or drinking hot, highly saturated saltwater solutions can sweat out or kill the Ebola virus (Fung et al., 2016). Public health agencies strongly advise against this practice. It does nothing to prevent or treat EVD and can cause severe illness and death from acute hypernatremia (Vijaykumar et al., 2019).
- Solutions containing silver nanoparticles act as powerful natural antimicrobials capable of neutralizing the Ebola virus inside the body (Fung et al., 2016). The WHO has explicitly stated that Nano Silver is an unproven compound with no demonstrated efficacy against Ebola. Authorities recommend avoiding these products, as silver accumulation can cause irreversible organ damage and a condition called argyria (which permanently turns the skin blue/gray).
- Consuming large quantities of specific botanical items, such as raw onions, ginger, or alligator peppers, can stave off infection (Nsoesie & Oladeji, 2020). These “natural cures” possess no therapeutic effects capable of stopping viral replication of the filovirus family. Relying on them creates a false sense of security, which delays life-saving, evidence-based triage and supportive care (Fridman et al., 2025; Nsoesie & Oladeji, 2020).
- Ebola has been attributed to spiritual curses or witchcraft that can only be reversed by traditional spiritual cleansing (Bedrosian et al., 2016). Public health organizations work alongside local communities to pivot away from these practices. Delaying medical intervention to seek traditional spiritual healing drastically increases community transmission and prevents patients from receiving SOTA antiviral therapies and fluid replacement, lowering survival rates (Obol & Nzedibe, 2024).
- A homeopath market “e-remedies” online, claiming that the “energy signature” of a remedy could be digitized into an audio file (Moffitt, 2018). He claimed that listening to a specific, hissing MP3 file could stimulate the body’s immune system to fight off Ebola. This prompted an investigation by the Medical Board of California into the doctor’s license for promoting unscientific and unproven online remedies (Moffitt, 2018).
- Some chiropractors claim that spinal manipulations can prevent Ebola infections, because misalignments interfere with the nervous system. Since the nervous system coordinates the immune responses, these misalignments weaken the body’s ability to recognize and destroy the Ebola virus (Terry Chiropractic Boulder). People “have nothing to fear but fear itself” regarding outbreaks if they keep their spines properly aligned to maximize their natural innate immunity. Global public health authorities and mainstream scientific institutions strongly reject these claims. There is zero credible scientific evidence demonstrating that manual spinal manipulation enhances immune competence or protects an individual against Ebola (Côté et al., 2020).
Ebola infection requires immediate, professional medical treatment. Treatments include monoclonal antibody therapeutics along with intensive supportive care. Relying on internet remedies significantly delays proper clinical treatment and increases the risk of mortality.

I found an interesting article in the hilarity-prone journal ‘HOMEOPATHY’. I hope it might amuse you:
The concept of antidotes in homeopathy holds a central place in classical doctrine and daily clinical practice, yet remains l argely unexplored in scientific literature. Antidotes are traditionally defined as substances, remedies, environmental factors or physiological and emotional influences capable of suppressing, altering or interrupting the action of a homeopathic medicine. From a classical homeopathic perspective, any factor capable of modifying the totality of symptoms—thereby influencing remedy selection and follow-up—may be regarded as a potential antidoting influence. Unlike conventional pharmacological antidotes, which act through molecular interactions, homeopathic antidoting is conceived as an interference with the organism’s adaptive and regulatory response. This review revisits the historical foundations of antidotes, examines their clinical importance and explores potential scientific re-interpretations grounded in contemporary neurobiology, psychophysiology and systems medicine. Classical authors, including Hahnemann, Kent, Allen and Boericke, are critically reviewed, and the phenomenon of antidoting is discussed in light of stress physiology, placebo–nocebo mechanisms, hormesis and network regulation. We propose that antidotes represent early empirical descriptions of system-level modulation rather than substance antagonism. Finally, research perspectives are outlined to encourage methodological investigation of antidoting using modern biomedical tools.
Homeopaths administer an antidote when they fear a remedy produces too strong a reaction, to moderate the response. According to homeopathic belief, accidental antidoting commonly occurs through exposure to things like:
- coffee,
- camphor,
- mint,
- menthol,
- eucalyptus,
- strong odors.
- essential oils,
- perfumes,
- toothpaste,
- emotional shock,
- physical shock,
- dental work,
- numerous drugs.
An antidote, according to homeopathic teaching, specifically stops the previous remedy’s action. Each remedy has particular antidotes; for example, Natrum muriaticum is antidoted with mint, while Arnica may be antidoted by coffee. I should add that this concept is, of course, not scientifically validated and therefore pure fantasy.
Has anyone seen a reaction to a homeopathic remedy that is too strong and needs moderation?
No?
Me neither!
Hold on, Arsenic D1 perhaps?
But I am sure the author does not refer to this scenario. Homeopathic remedies are understood to be highly diluted; they contain nothing – even if it says Arsenic on the label. Placebos do not need antidotes because they don’t cause strong reactions.
Therefore, antidotes to homeopathy are a nonsense!
Hold on, this might not be correct. I just thought of a powerful antidote to homeopathy:
SCIENCE!
Homoeopathy and I is the title of a paper that I published in 2009. My aim was to denounce the popular notion that held I had started my research with a grudge against homeopathy. The honest truth is that – if anything – my attitude was even slightly positive. Here is the key section from this 2009 paper:
In 1993, I was appointed to the world’s first Chair in Complementary Medicine, and it became my job to investigate scientifically all sorts of complementary treatments, including homoeopathy. In the course of this activity, my co-workers and I published numerous articles on homoeopathy. Systematically, reviewing the totality of my publication list, I found a total of 46 papers with ‘homeopathy’ in the title. The following quotes from these articles were selected to best describe my attitude toward homoeopathy at the time:
• Homeopathicremedies are believed by doctors and patients to be almost totally safe (8).
• It might be argued that arnica …is ineffective but homeopathy may still works (9).
•…only 23% of Australian homeopaths believe that immunisation is important (10).
• Homeopathy, I fear, has soon to come up with … more convincing evidence (11)…
• Future evaluations of homeopathy should be performed to a high scientific standard (12)…
•…studies on the safety of the practice of homeopathy must not be ignored (13)…
•…systematic reviews based on Medline searches can lead to similar (possibly slightly less positive) overall conclusions (14)…
•…a detailed eye-witness account claiming that all attempts [by researchers during the ‘Third Reich’] to show that homeopathy works has led to negative results (15).
•…the best way forward is clearly to do rigorous research (16)…
• Thus, the question of whether homeopathy works or not has remained unanswered for 200 years (17).
• The most pressing question, ‘Is homeopathy clinically more effective than placebo’, needs to be answered conclusively (18).
• There is evidence that homeopathic treatment can reduce the duration of ileus (19)…
• Some of the well-argued cases against homeopathy should become essential reading for all homeopaths (20).
•…the published evidence to date does not support the hypothesis that homeopathic remedies … are more efficacious than placebo (21)…
•…homeopathic remedies are associated with the same clinical effects as placebo (22).
•…the picture painted by Linde and colleagues … may well be slightly more positive (23)…
•…[our] goal is to conduct rigorous, impartial research in [homeopathy] (24)
• The claim that homeopathic arnica is efficacious beyond a placebo effect is not supported by rigorous clinical trials (25).
• The results of recent systematic reviews are not uniform (26).
•…at present, the relative efficacy of homeopathic remedies is not known (27).
• The results of recent systematic reviews are obviously far from uniform (28).
•…the trial data … do not suggest that homeopathy is effective (29)…
•…the definitive answer, in my view, has to come from a series of rigorous trials (30).
• Large, multicentre trials of homeopathic remedies … represent the best way of advancing the debate (31).
•…the re-analysis of Linde et al. can be seen as the ultimate epidemiological proof that homeopathic remedies are, in fact, placebos (32).
•…randomised clinical trials … do not allow a firm conclusion as to the effectiveness of homeopathic remedies (33).
•…both homeopaths and university heads of medical departments clearly advocate further research into the effectiveness of homeopathy (34).
•…homeopathy is not different from placebo (35).
•…the best clinical evidence … does not warrant positive recommendations (36).
•…the evidence is insufficient for firm recommendations (37).
•…the results of this trial do not suggest that homeopathic arnica has an advantage over placebo (38)…
-
- This study provides no evidence that adjunctive homeopathic remedies … are superior to placebo(39).
•…this systematic review does not provide clear evidence that the phenomenon of homeopathic aggravations exists (40).
•…Mathie’s methodology was not as strong as it should have been, and this deficit has led to conclusions that may be falsely positive (41).
•…homeopathy may actually be more expensive than good conventional care (42).
•…the proven benefits of highly dilute homeopathic remedies … do not outweight the potential for harm (43).
•… homeopathic remedies are placebos, but homeopaths can be skilled doctors who may significantly help their patients (44).
• Our analysis … found insufficient evidence to support clinical efficacy of homeopathic therapy (45)…
•… promotion can be regrettably misleading, dangerous and counterproductive (46).
•…do we condone treatments because of their popularity or their effectiveness? (47)
•…homeopathy is not based on solid evidence and, over time, this evidence seems to get more negative (48).
• The evidence from rigorous clinical trials … testing homeopathy for childhood and adolescence ailments is not convincing enough for recommendations in any condition (49).
• There is no evidence at all that homeopathic remedies can change the natural history of any cancer (50).
•…context effects of homeopathy … are entirely sufficient to explain the benefit many patients experience (51)…
• Amongst all the placebos that exist, homeopathy has the potential to be an exceptionally powerful one (52)…
•…recommendations by professional homeopathic associations are not based on the evidence (53)…

Since then (2009) I – often together with others – have published several further articles with “homeopathy” in the title. This means that my original paper needs updating. Here are the titles of (and links to) these articles (appologies, if I missed a few):
- Should we maintain an open mind about homeopathy?
- Homeopathy
- Homeopathy: what does the “best” evidence tell us?
- Homeopathy, non-specific effects and good medicine.
- A systematic review of homoeopathy for the treatment of fibromyalgia.
- Homeopathy, a “helpful placebo” or an unethical intervention?
- The ethics of British professional homoeopaths.
- Homoeopathy debate. Protecting patients?

- Homeopathy in severe sepsis.
- Call for doctors not to practice homeopathy or refer to homeopaths.
- Homeopathy for eczema: a systematic review of controlled clinical trials.
- The most thorough assessment to date of homeopathy
- Should doctors recommend homeopathy?
If you study these articles, you will find that my arguments around homeopathy remained entirely evidence-based. The overall point is, I hope, clear: I did not embark on my research into homeopathy aiming to disprove it or to dismiss it outright [a claim I still hear with some regularity]. To begin with (in 1993), I was not only open but positively inclined. At all times, however, I was keen to follow the best available evidence. If my attitudes/verdicts became less and less positive, it is merely because the evidence became more and more overtly negative.
Chronic non-specific low back pain (CNSLBP) is a major cause of disability worldwide. Conventional pharmacological treatments offer limited benefits and carry potential risks, prompting interest in alternative approaches, including homeopathy. The objective of this study was to evaluate the short-term efficacy and safety of a standardised homeopathic biotherapic (Lumbar Vertebra, LM2 potency) for CNSLBP.
A randomised, double-blind, crossover, placebo-controlled clinical trial was conducted with 120 participants diagnosed with CNSLBP. Participants received both the biotherapic and placebo in two treatment phases separated by a washout period. The primary outcome was pain intensity (numeric rating scale); secondary outcomes included functional disability (Oswestry Disability Index), adverse events and use of pain medications. Data were analysed using random effects generalised linear models.
Both the biotherapic and placebo interventions led to significant within-group reductions in pain and disability (p = 0.001 and p < 0.001 respectively). However, no statistically significant differences were observed between the two interventions for either outcome (pain: p = 0.435; disability: p = 0.840). The magnitude of change in pain intensity did not reach the pre-defined minimal clinically important difference (MCID), and mean pain scores at the study endpoint remained above the inclusion threshold. Adverse events were mild and comparable across groups.
The authors concluded that no specific effect of the Lumbar Vertebra LM2 biotherapic was demonstrated. Improvements are likely due to non-specific effects such as the therapeutic environment, patient expectations and placebo response. Clinicians should consider the substantial role of non-specific responses in CNSLBP and avoid medications with unfavourable risk–benefit profiles.
One the one hand, the authors from the Department of Medicine, Federal University of São Carlos, São Carlos, Sao Paulo, the School Health Unit, Federal University of São Carlos, São Carlos, Sao Paulo, and the epartment of Social Medicine, Ribeirão Preto Medical School, University of São Paulo, Ribeirão Preto, Brazil should be congratulated for publishing a squarely negative result in the journal ‘Homeopathy’ that is known for publishing even the most implausible positive findings.
On the other hand, one might criticise them: why on earth did they ever conceive the hypothesis that homeopathy in general or “Lumbar Vertebra LM2 biotherapic” in particular might be effective for CNSLBP (the study did not receive any funding or financial support, apart from the study medications donated by HN-Cristiano Pharmacy (Santana, São Paulo, Brazil), which had no role in the study design, data collection, analysis, interpretation or discussion of the results)? I have never met a homeopaths who would make such a claim, and one could easily argue that such a trial is an unethical waste of resources.
Insomnia is a prevalent disorder that is associated with substantial impairment. Homeopathy has been proposed as a complementary treatment for insomnia, but its clinical effects remain uncertain.
This systematic review assessed the efficacy, effectiveness, and safety of homeopathic treatments for insomnia. Prospective comparative studies evaluating any homeopathic preparation for insomnia were included. Searches in MEDLINE, EMBASE, seven additional databases, and three trial registries were conducted through August 2025. Risk of bias, intervention complexity, model validity, and pragmatism were assessed using respectively RoB 2, ROBINS-I, iCAT, MVHT, and RITES. Data were synthesized using random-effects meta-analyses, and certainty of evidence was evaluated using GRADE.
Eight randomized controlled trials (RCTs; n = 364 participants) and four non-randomized studies (NRSIs; n = 517) met the inclusion criteria. In adults, sleep quality (MD = −2.6 points; 95% CI −5.5 to 2.6; low certainty) and insomnia severity (MD = −3.2; 95% CI −5.68 to −0.72, moderate certainty) were reported in one RCT each. For total sleep time, the pooled MD of three RCTs was 0.65 hours (95% CI −0.9 to 2.2; low certainty). In children, one open-label RCT suggested a difference in insomnia severity, but certainty of evidence was very low. Adverse events were rarely reported, resulting in low certainty evidence.
The authors concluded that the current evidence is mainly limited by imprecision and risk of bias. The available evidence does not allow firm conclusions regarding the effects of homeopathy for insomnia. High-quality, replicated trials with systematic adverse event monitoring are needed.
15 years ago, I published a similar review entitled “Homeopathy for insomnia and sleep-related disorders: a systematic review of randomised controlled trials” (Focus on Alternative and Complementary Therapies Volume 16(3) September 2011 195–199)). Here is its abstract:
The aim of this review was the critical evaluation of evidence for the effectiveness of homeopathy for insomnia and sleep-related disorders. A search of MEDLINE, AMED, CINAHL, EMBASE and Cochrane Central Register was conducted to find RCTs using any form of homeopathy for the treatment of insomnia or sleep-related disorders. Data were extracted according to predefined criteria; risk of bias was assessed using Cochrane criteria. Six randomised, placebo-controlled trials met the inclusion criteria. Two studies used individualised homeopathy, and four used standardised homeopathic treatment. All studies had significant flaws; small sample size was the most prevalent limitation. The results of one study suggested that homeopathic remedies were superior to placebo; however, five trials found no significant differences between homeopathy and placebo for any of the main outcomes. Evidence from RCTs does not show homeopathy to be an effective treatment for insomnia and sleep-related disorders.
The findings of the two reviews are remarkably similar. For the following reasons, I find this notable:
- One would have hoped that 15 years are a long enough time for clarifying the issue, particularly as insomnia is not an unimportant condition for homeopathy.
- The new review is authored by well-known proponents. It seems unexpected that they (almost) go as far as admitting that the evidence for homeopathy as a treatment for insomnia is not positive.
- We have here, I think, a textbook example of how proponents of homeopathy prettify results that do not confirm their belief.
SO FAR, SO GOOD.
But now consider this: There are two further reviews of the same subject!
The first is entitled “Homoeopathy for insomnia: A meta-analysis of clinical evidence – Journal of Integrated Standardized Homoeopathy“. Here is its abstract:
Objectives: Insomnia is a prevalent sleep disorder characterised by challenges in initiating, maintaining or achieving restorative sleep, resulting in compromised daytime functionality. Traditional therapeutic modalities frequently encompass pharmacological treatments, which may have adverse effects and potential for dependency. Numerous patients pursue alternative methodologies, such as homoeopathy, which is attributed to its personalised, holistic and non-invasive treatment framework. This thorough examination assesses the effectiveness of homoeopathy in promoting better sleep quality and overall wellness in people with insomnia by analysing randomised controlled trials (RCTs).
Material and Methods: This meta-analysis sought to ascertain whether homoeopathy induces a statistically significant enhancement in the management of insomnia, concentrating on aspects of sleep quality, duration and general well-being. All RCTs addressing insomnia treated with homoeopathic interventions were included in this review. All studies were meticulously documented in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three evaluators independently reviewed and compiled the literature, extracting comprehensive details regarding participants, study designs, therapeutic interventions and follow-up pertaining to homoeopathic treatment. The primary outcome of the investigation was disease assessment based on sleep diary scores, with an additional outcome being the enhancement of quality of life.
Results: The analysis revealed that homoeopathic remedies exhibited statistically significant improvement over placebo in the management of insomnia. The overall pooled effect size, standardised mean difference (random), was −0.60, standard error (random) was 0.42 and confidence interval (random) at 95% ranged from −0.93 to −0.26. The risk of bias was assessed for all studies.
Conclusion: This meta-analysis shows that homoeopathic remedies are effective in treating insomnia, but more studies are required for accuracy.
The last review is entitled “Effectiveness of Homeopathic Interventions for Insomnia and Sleep Disorders: A Systematic Review and Meta-Analysis“. Here is its abstract:
Insomnia is a common sleep disorder, and many individuals seek alternative treatments like homeopathy. However, evidence for its effectiveness remains controversial. This systematic review and meta-analysis evaluated the effectiveness of homeopathic interventions for insomnia and sleep-wake disorders. A comprehensive search of PubMed, MEDLINE, CINAHL, and the Cochrane Library was conducted for studies published between 2010 and 2025. We included randomized controlled trials (RCTs) and non-randomized studies involving adults (≥18 years) with primary insomnia receiving any homeopathic intervention compared to placebo, no treatment, or active care. Primary outcomes included validated sleep quality measures (e.g., Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI). Four reviewers independently performed study selection, data extraction, and risk of bias assessment using RoB 2.0 and ROBINS-I. A random-effects meta-analysis was conducted for controlled trials, and a narrative synthesis for non-randomized studies. Certainty of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE). The search yielded 1304 records; 12 studies (nine RCTs and three non-randomized) met inclusion criteria. Meta-analysis showed a large, statistically significant positive effect of homeopathy on sleep outcomes (SMD = 0.81, 95% CI [0.24, 1.38], p = 0.0055), with substantial heterogeneity (I² = 86.04%) and publication bias (Egger’s test, p = 0.0079). Most studies had high or critical risk of bias, and overall certainty was low. Homeopathic interventions showed a large positive effect on sleep outcomes, but due to high bias, heterogeneity, and publication bias, evidence remains low-certainty and insufficient to support effectiveness. High-quality RCTs are needed.
What should we make of this?
We now have two reviews concluding that there is no good evidence and two implying that homeopathy is effective for insomnia! This clearly demonstrates how easy it is to mislead the public with seemingly rigorous reviews.
I must say, I pity all the interested lay people who are trying to make sense of this mess.
How can they arrive at the best available, most reliable evidence?
We have here, I think, another textbook example; one of how important it is to run reality checks. But surely, we cannot possible ask of a lay person to understand why the last two reviews are badly misleading. What we need is an accessible tool for differentiating the science from the pseudoscience, the reliable from the unreliable.
Unfortunately, such a tool does not exist. But there are a few indicators:
- Is the journal that published the review reputable?
- Are the authors affiliated to reputable institutions?
- Do the authors have a history of critical analysis or one of uncritical promotion?
- Do they explain clearly and provide the essential details of their work?
These are issues that lay people might be able to check relatively easily. The above 4 reviews demonstrate that using them does not always provided an entirely clear cut-off. However, it might give some valuable pointers into the right direction.
Following my post about the decline in homeopathy-use in Europe, several people dismissed it by saying something like this: Who cares about Europe? Across the globe, homeopathy is state-funded in a majority of countries!!!
This is NOT correct. A correct description of the situation would be that homeopathy is currently state-funded or reimbursed in a minority of countries. In most other countries, it is paid out of pocket or covered only by private insurance. Yes, homeopathy is integrated into national health systems in some countries, explicitly listing Brazil, Chile, India, Mexico, Pakistan, and Switzerland, but this is NOT the global norm.
The counter-argument by homeopathy-fans is this: The states that support homeopathy tend to be very large (e.g. India and Brazil). Therefore, the majority of the world population has access to state-sponsored homeopathy.
This statement seems to be false as well. It is true, of course, that India alone accounts for about 18% of the world’s population, and India does publicly support homeopathy through its health system and the Ministry of AYUSH. But the claim that, for the majority of the world population, homeopathy is state-funded is not based on good evidence. Most of the world’s population lives outside the small number of countries where homeopathy is publicly reimbursed or embedded in state systems.
Even with India included, the evidence available here does not justify a world-population majority claim. The publicly supported/reimbursed countries are still a rather small group, and, as far as I can see, they constitute neither most countries nor most of humanity. In several large countries homeopathy-use exists without state funding or with only private coverage, which weakens any global majority argument. Should someone nevertheless claim that “the majority of the world population has access to state-sponsored homeopathy”, I would ask him or her to show me the evidence for the claim. As far as I can see, it does not exist.
A more accurate statement would therefore be the following:
A substantial share of the world’s population lives in countries where homeopathy has some level of state support, mainly because of India, but there is no good evidence to prove that this amounts to a majority of the world population.
Despite overwhelming evidence proving that homeopathics are pure placebos, a faction of German healthcare professionals – predominantly people who profit from homeopathy – continues to argue against their removal from statutory insurance. They claim that defunding homeopathy would eliminate vital treatment options, ultimately driving patients toward more expensive conventional interventions. However, from a health economics perspective, this argument is fundamentally flawed; subsidizing treatments that lack proven efficacy is not a cost-saving measure, but rather a misallocation of limited healthcare resources.
Recognizing this inconsistency, German policymakers have finally shifted towards a more evidence-based approach. The federal cabinet recently approved a draft law to reform the statutory health insurance system, which includes a pivotal provision: homeopathic and anthroposophic medicines, along with their associated services, will no longer be eligible for reimbursement as optional benefits (Satzungsleistungen) by public insurers.
This legislative move serves as a long-overdue correction to a historically irrational policy that was initiated by the Nazis during the Third Reich. Excluding these treatments, the government is now finally acknowledging that public healthcare contributions should not fund therapies devoid of scientific backing. This decision brings Germany in line with other European countries like France and the UK, and marks a significant alignment of national policy with the dual principles of evidence-based medicine and responsible fiscal management.
At its core, this reform addresses a long-standing critique of how so-called alternative medicine (SCAM) has been integrated into the German healthcare system. For many decades, institutional tolerance allowed ineffective treatments to gain a veneer of legitimacy and public financing. Consequently, this shift is more than a mere technical adjustment; it represents a symbolic turning point in the relationship between science, medicine, and public policy.
The removal of homeopathy from insurance coverage is undoubtedly both scientifically justified and economically imperative. It signals a decisive transition of German medicine towards a more rational, evidence-based healthcare system that prioritizes proven outcomes over tradition.
Guest post by Udo Endruscheit
Two years ago, in a guest post on this blog, I described the long and winding history of homeopathy in Switzerland — a story marked by political expectations, institutional entanglements, and repeated attempts to reconcile a lack of evidence with a desire for legitimacy. I ended that article with the hope that the country would not embark on yet another “honour lap” around the same unresolved questions.
In 2024, however, Switzerland initiated a new evaluation of homeopathy — a renewed attempt to clarify its role within the national health insurance system. It was, in many ways, the beginning of yet another loop in the same story.
Now, in 2026, that loop has come to an unexpected end. The evaluation was halted.
Not postponed, not softened, not watered down — simply stopped.
And this stop is not merely a political gesture. It marks the structural endpoint of a system that has exhausted its internal possibilities.
A system designed to avoid the evidence question
To understand why Switzerland has arrived at this point, one must look beyond the political headlines and examine the institutional landscape that has shaped the country’s approach to homeopathy for more than a decade.
Three elements are central:
- The political mandate created by the 2009 referendum, which placed homeopathy and other CAM modalities into the basic health insurance package.
- The professional environment, in which thousands of Swiss physicians hold CAM qualifications and the national medical association (FMH) views integrative medicine positively.
- The academic anchor, the Institute for Complementary and Integrative Medicine (IKIM) at the University of Bern, which provides an appearance of scientific legitimacy without producing evidence capable of resolving the core question of efficacy.
This combination created a system in which homeopathy became institutionally normalised — not because of evidence, but because of political and professional expectations.
The HTA as a detour — and the beginning of the dead end
When the Federal Office of Public Health (BAG) was tasked with evaluating homeopathy after the referendum, it faced an impossible dilemma:
- The clinical evidence was weak to non‑existent.
- The political expectation was strong.
- A direct assessment of the evidence would have produced a negative result.
The solution was a detour: a Health Technology Assessment (HTA). But HTAs are not designed to determine efficacy. They assume efficacy has already been established through robust clinical research. Their purpose is to assess cost‑effectiveness, safety, and system impact.
The Swiss HTA did the opposite. In its conclusion, it stated:
“The effectiveness of homeopathy can be considered as proven when internal and external validity criteria are taken into account.”
This is a remarkable inversion of the HTA principle. The report asserted efficacy — without the evidence required to do so — while simultaneously admitting that the actual HTA questions (such as cost‑effectiveness) could not be answered reliably.
In retrospect, this HTA was not the beginning of a solution. It was the beginning of a dead end. A system that asserts efficacy without evidence cannot move forward. It can only circle around itself.
The IKIM: an academic structure without academic function
The IKIM at the University of Bern has played a central role in stabilising this circular logic. Its research output is broad in appearance but narrow in substance. It avoids the central question of efficacy and instead focuses on:
- sociological aspects,
- patient satisfaction,
- model validity,
- and experimental approaches that are not independently reproducible.
The IKIM does not produce evidence. It produces normality — the impression that homeopathy is a legitimate academic field simply because it is housed within a university.
This normality has been crucial for maintaining the political and professional acceptance of homeopathy in Switzerland. But it has also contributed to the structural dead end: an academic institution that cannot resolve the evidence question because it is not designed to ask it.
The 2026 decision: not a surprise, but a consequence
Against this background, the 2026 decision to halt the renewed evaluation of homeopathy is not really surprising. It is the logical endpoint of a system that has exhausted its internal possibilities.
- The evidence has not improved.
- The HTA detour has failed to provide a foundation.
- The institutional structures have stabilised expectations but not knowledge.
- The political mandate cannot be fulfilled without contradicting scientific standards.
The result is a dead end. Not because anyone wanted it, but because the system was built in such a way that no other outcome was possible.
A lesson beyond Switzerland
The Swiss case is often cited by proponents of homeopathy as a model of political and professional acceptance. But the 2026 decision reveals a different lesson:
A system that tries to reconcile political expectations with a lack of evidence will eventually reach a point where it can neither move forward nor turn back.
Switzerland has reached that point. The “endless story” of homeopathy in the Swiss health system has not been resolved — but it has reached its structural conclusion.
And unfortunately that conclusion is not a triumph of evidence. It is the recognition that evidence cannot be replaced by institutional normality. But one thing it certainly isn’t: an endorsement of homeopathy, even if its advocates will once again try to interpret it that way.
Tonsillitis is a common condition predominantly affecting children and adolescents, presenting as acute, recurrent, or chronic infection. This review evaluated the effectiveness of homeopathy for clinical improvement and recurrence prevention across all tonsillitis presentations.
A team of scientists searched nine databases and four trial registries for randomised controlled trials (RCTs) and non-randomised controlled trials (nRCTs) involving patients of all ages with diagnosed tonsillitis. Studies examining individualised homeopathy (IH) and non-individualised homeopathy (non-IH) were included, compared with an inactive or active control group. Primary outcomes were clinical improvement (symptoms and signs) and recurrence. Secondary outcomes were antibiotic consumption, healthcare utilisation, quality of life, costs, and adverse events. Data extraction, Risk of Bias assessment, and certainty of evidence evaluation (GRADE) followed established methodology.
Five RCTs compared homeopathy with placebo (n=4) or standard care (n=1): one used IH, one used both IH and non-IH, and three used non-IH. Two RCTs examined acute tonsillitis, two examined recurrent tonsillitis, and one examined chronic tonsillitis. Three trials enrolled children, one enrolled adults, and one enrolled a mixed population. Sample sizes ranged from 30 to 256. Substantial heterogeneity across populations, interventions, and outcomes precluded meta-analysis. Individual RCTs showed that, in acute tonsillitis, non-IH achieved short-term symptom improvement. In recurrent tonsillitis, both IH and non-IH were associated with reduced infection recurrence, lower antibiotic consumption, and improved quality of life, with the strongest evidence for a standardised non-IH complex (SilAtro-5-90). In chronic tonsillitis, IH showed delayed but consistent improvements in symptoms, recurrence, healthcare utilisation, and quality of life by 2–3 months, with early outcomes favouring placebo. The certainty of evidence for all outcomes was low. No serious adverse events were reported.
The authors concluded that the evidence from individual trials suggests that both individualised and non-individualised homeopathy may benefit clinical improvement, reduce infection recurrence, reduce antibiotic use, and enhance quality of life in tonsillitis, with no safety concerns reported. However, substantial heterogeneity across studies and methodological limitations restrict the ability to draw definitive conclusions about homeopathy’s effectiveness in patients with tonsillitis. Further well-designed, adequately-powered trials with standardised outcomes and consistent methodological approaches are needed to strengthen the evidence base and enable more robust conclusions.
My critical evaluation of this paper is impeded by the fact that two of its authors were once members of my own team. On the one hand, this might assure me that their review is of a high standard, on the other hand it hinders me to voice harsh criticism. Fortunately, they include their own valid criticism of their project:
One study was a pilot study and therefore not appropriately powered [36] and one was published by a single researcher not following a formal publication protocol or underwent a formal peer-review process [34]. One study used an add-on design [31] which is a recognised methodology in clinical research, not unique to homeopathy, and their limitations regarding attribution of effect are well understood and acknowledged. We do acknowledge the possibility of publication bias and the limitations of a small evidence base. We also note there are issues arising from numerous outcomes, subscales, and repeated time-point analyses, which substantially increases the likelihood of false-positive findings.
Further variability was introduced by unclear definitions of some secondary outcomes and by differences in definitions across studies. Two of the five studies reported on their funding body. One did not receive funding [37] and Palm et al., 2017 [31] was sponsored by Deutsche Homoopathie-Union, DHU-Arzneimittel GmbH & Co. Germany.
They also are open about the funding of their work:
Existing funds held by Homeopathy Research Institute (HRI) – donated by Manchester Homeopathic Clinic Charitable Trust – were donated to University of Bristol to conduct the systematic review. The funders had no involvement in the study design; in the collection, analysis and interpretation of the data; in the writing of the report; and in the decision to submit the paper for publication.
So, what should we make of their effort? Let me just state this:
If I had to advise them on how to improve their review substantially, I would have suggested they re-phrase their conclusion. I am sure that something like this would have been much more adequate:
Most of the included trials were positive yet, because of substantial heterogeneity and methodological limitations of the primary studies, the evidence collectively fails to show that individualised or non-individualised homeopathy are effective treatments for tonsillitis.
