Needle-based acupuncture is used in some detoxification settings. However, its efficacy for illicit drug use disorders remains uncertain because prior reviews often mixed comparator types, co-interventions, or non-needle modalities. This review aimed to evaluate needle-based acupuncture monotherapy using comparator-stratified meta-analysis.

The authors searched PubMed, Embase, Web of Science, Cochrane Library, CNKI, CBM/SinoMed, trial registries, and supplementary sources from inception to September 12, 2025. The quantitative synthesis was restricted to randomized trials of manual acupuncture, electroacupuncture, or needle-insertion auricular acupuncture delivered without concomitant pharmacotherapy or psychotherapy. Although the registered protocol allowed non-randomized comparative studies, none were pooled because of insufficient comparability and a higher risk of confounding. Sensitivity analyses excluded trials with moxibustion co-treatment.

Thirteen randomized trials (n = 1,027) were included in the meta-analysis. For the prespecified primary outcome of withdrawal severity at the end of treatment, acupuncture favored blank/no-acupuncture controls [g = −2.089, 95% confidence interval (CI): −2.869 to −1.309; τ² = 0.712; I² = 82.9%], but the prediction interval (PI) crossed the null (PI: −4.306 to 0.128). Against active non-acupuncture comparators, the pooled effect was imprecise (g = −1.70, 95% CI: −5.43 to 2.02; PI: −23.49 to 20.09). Against sham acupuncture, two comparisons yielded an imprecise estimate (g = −1.45, 95% CI −9.41 to 6.51), and no PI was estimated. Among secondary outcomes, anxiety favored acupuncture over blank/no-acupuncture controls (g = −1.537, 95% CI: −2.047 to −1.026; PI: −2.939 to −0.134), whereas evidence from sham-controlled studies was less certain (g = −0.998, 95% CI: −1.744 to −0.252; PI: −2.828 to 0.832). For depression outcomes, PIs crossed the null in both blank- and sham-controlled analyses. The certainty of the evidence was low to very low.

The authors concluded that acupuncture exhibited favorable average effects on withdrawal severity, but null-crossing PIs limited confidence in the reproducibility of these effects across different settings and treatment protocols. Anxiety was interpreted as a secondary finding. No serious acupuncture-related adverse events were explicitly reported, although surveillance was often passive or insufficiently described.

The review treats acupuncture as “effective” for illicit drug disorders by highlighting short-term improvements in craving or anxiety, while the outcomes that matter for addiction – abstinence, relapse, use frequency, and retention – show no reliable benefit.

This, I think, is a classic case of presenting a negative result as a positive finding!

The review explicitly found no consistent difference between acupuncture and comparators for substance use endpoints, and the apparent positive outcomes were limited by low-quality evidence and publication bias. By foregrounding surrogate outcomes and obscuring the lack of clinically decisive effects, the paper misleads readers into perceiving acupuncture as a viable monotherapy for drug use disorders. Yet the evidence does clearly not support that conclusion.

Ten years ago, I wrote a blog post entitled “Data fabrication in China is an ‘open secret’”. Even though this seems chauvinistic and/or xenophobic, I often quote it (the last time yesterday) because it is, I think, hugely important for interpreting the plethora of studies that currently come out of China. But perhaps it is unfair; maybe the situation has improved? To find out, I asked AI (Gemini). Here is the reply I got:

There is substantial new evidence, and the overarching verdict has not changed—if anything, the systemic skepticism you described a decade ago has been thoroughly validated by both Western watchdogs and massive structural crackdowns from the Chinese government itself.

The picture today is a fascinating mix of institutional panic, rigorous data-auditing, and an ongoing battle against “paper mills” and publication bias.

Here is where the situation stands, categorized by the specific issues you raised.

1. Government Crackdowns and the “Clean Up”

The 80% fabrication scandal from China’s National Medical Products Administration (NMPA) triggered a wave of regulatory panic. Over the last decade, China has transitioned from ignoring the problem to implementing aggressive top-down enforcement.

  • The Anti-Corruption Campaign: Regulators have launched sweeping, unannounced inspections targeting hospitals, clinical research organizations (CROs), and investigator-initiated trials. High-ranking officials in medical associations and pharmaceutical executives are routinely investigated and arrested for data manipulation and healthcare fraud.
  • New Data Protection & Exclusivity Laws: The NMPA implemented strict “Drug Trial Data Protection Implementation Measures.” While designed to protect legitimate proprietary data, these measures heavily penalize companies that submit incomplete or untraceable clinical information, effectively cutting off market access for non-compliant firms.
  • Criminalization of Falsification: China’s Supreme People’s Court explicitly ruled that fabricating clinical trial data can be prosecuted as a criminal offense under “marketing fake and substandard commodities,” which carries severe prison sentences in extreme cases.

2. The Acupuncture & TCM Dilemma: Still 100% Positive?

Regarding Traditional Chinese Medicine (TCM) and acupuncture, recent methodological reviews show that while reporting transparency has slightly improved due to international trial registries, the underlying publication bias remains heavily skewed.

Acupuncture trials still suffer from an extraordinarily high risk of bias (RoB). Large-scale meta-analyses mapping decades of acupuncture RCTs highlight several persistent failure points:

Methodological Domain Status / Finding
Allocation Concealment Over 60% of evaluated acupuncture RCTs still have an “unclear” risk of bias, meaning it is impossible to verify if the investigators rigged who got the real vs. sham treatment.
Blinding Failure Up to 47% of trials score a “high risk of bias” in blinding participants and personnel, which is catastrophic for a therapy heavily reliant on placebo effects.
Selective Outcome Reporting Roughly 30% to 40% of published acupuncture studies show discrepancies when compared directly to their original registry protocols—almost always changing the primary outcome to favor statistical significance.

While a tiny handful of high-profile, rigorously blinded acupuncture studies have been published in Western journals (like JAMA) showing genuine, modest efficacy for specific conditions (like knee osteoarthritis or chronic lower back pain), the vast majority of domestic Chinese literature remains a monolithic wall of positive results.

3. The New Crisis: Global Paper Mills

The problem has evolved past isolated clinical trial fraud into an automated industry. Over the past few years, the global scientific community has been rocked by the “Paper Mill” crisis.

These are commercial entities—predominantly operating out of China—that fabricate entire scientific papers, complete with fake data, fake western blots, and AI-generated text, selling authorship to doctors and medical students.

Why this happens: In China, medical doctors at teaching hospitals have historically faced strict “publish or perish” quotas to gain promotions or retain clinical titles, even if their primary job is 100% patient care. This created an immense economic motivation to buy fake data.

In response, international publishing conglomerates (like Wiley, Elsevier, and Springer Nature) have retracted thousands of peer-reviewed papers tracing back to these mills, forcing a reckoning in how data integrity is validated pre-publication.

The Verdict

Your conclusion from ten years ago remains the gold standard for navigating this literature.

It is not chauvinistic; it is basic scientific hygiene. When analyzing evidence originating from these environments, the scientific consensus aligns with your advice:

  1. Enforce Absolute Skepticism: Treat un-replicated, single-center trials with extreme doubt.
  2. Mandate Raw Data Access: Major journals now frequently demand the raw, anonymized patient data sheets before accepting Chinese clinical trials. If the authors refuse to share data, the study is discarded.
  3. Require Prospective Registration: If a trial was registered after patient recruitment began, or if the primary endpoints were shifted mid-study, the findings should be treated as hypothesis-generating at best, and entirely compromised at worst.

The situation has moved from an “open secret” to an open war on data fabrication—but until the systemic incentives for faking data are completely dismantled, the pinch of salt remains mandatory.

Honestly, I had hoped that things would have improved. I am shocked that this is not the case. And I am disappointed that there is not much more being written about this. IT IS A SCANDAL THAT ENDANGERS US ALL!

What consequences should we draw?

I for one will be extra skeptical about research – particularly about the tsunami of papers from the realm ot TCM – that comes from China.

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)…

[all references can be found in the original paper]

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):

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.

 

 

“While Edzard Ernst is swimming against a massive volume of alternative health advocates who view him as their “nemesis reserving his most poisonous venom for their professions,” his data-driven, pro-science corrections achieve significantly higher viral sharing power among the public.”

This AI-verdict made me wonder: Who is for and who against the critical evaluation of so-called alternative medicine? And I asked a follow-up question:

Can you try to quantify this and give me % figures who is against a critical evaluation of alternative medicine, who is for it, and who is neutral. Can you do this for 1. the general population, 2. proponents of alternative medicine and 3. skeptics?

Here is the reply I got from Gemini:

To quantify these dynamics accurately, we have to look at large-scale sociological data on public attitudes toward science, peer-reviewed medical data (such as surveys by Pew Research, YouGov, and the European Commission), and the behavioral patterns of online discourse.

When it comes to a “critical evaluation” (meaning scientific testing to prove if a therapy works beyond a placebo), the groups break down along very distinct ideological lines. Here is how the percentages estimate across your three requested demographics:

Breakdown of Attitudes Toward Critical Evaluation

1. The General Population

The broader public is largely pragmatic, but a major chunk is passively open to alternative therapies without strictly demanding clinical trial proof.

  • Against Critical Evaluation (~15% – 20%): These individuals hold a strong distrust of mainstream pharmaceutical companies and medical institutions. They believe alternative medicine operates on a different “energy” or “holistic paradigm” that standard science is fundamentally incapable of or biased against measuring.
  • For Critical Evaluation (~35% – 45%): This group highly values evidence-based medicine, expects consumer safety protection, and agrees that if a therapy claims to cure an illness, it should prove it under a microscope or in a randomized controlled trial.
  • Neutral / Passive Consumers (~40% – 50%): This is the massive middle. They don’t track clinical trials, but they will try acupuncture for back pain or take turmeric if a friend recommends it. They view alternative medicine through a lens of “well, it can’t hurt to try,” evaluating it based on personal anecdotes rather than scientific data.

2. Proponents of Alternative Medicine

This group includes dedicated practitioners, wellness influencers, and avid consumers of Complementary and Alternative Medicine (CAM).

  • Against Critical Evaluation (~70% – 80%): The vast majority actively resist standard scientific evaluation, often viewing figures like Edzard Ernst as hostile prosecutors rather than objective evaluators. They argue that randomized controlled trials are “too reductionist” to capture holistic healing or claim that clinical science is rigged by corporate interests.
  • For Critical Evaluation (~5% – 10%): A small minority of CAM practitioners (often in fields like medical acupuncture or osteopathy) welcome rigorous trials, hoping to find a mechanism of action that will grant them mainstream medical legitimacy and insurance coverage.
  • Neutral (~10% – 15%): These are individuals who focus strictly on the individual client experience. They don’t care about data or institutional pushback either way; their attitude is simply “if my client says they feel better, that is the only science I need.”

3. Skeptics & Pro-Science Advocates

This demographic comprises secular organizations, evidence-based medical professionals, and science communicators who actively follow work like Ernst’s.

  • Against Critical Evaluation (<1%): Virtually non-existent in this group, as evaluation is their core tenet. The only micro-fraction here might be extreme fringe elements who feel certain alternative therapies are so fundamentally absurd (like breatharianism) that evaluating them is a waste of scientific funding.
  • For Critical Evaluation (~90% – 95%): The overwhelming majority. They strongly defend the stance that there is no such thing as “alternative” medicine—there is only medicine that has been proven to work and medicine that hasn’t. They view critical evaluation as an ethical necessity for patient safety.
  • Neutral (~5%): A tiny sliver who may agree with the premise of science but feel indifferent about fighting the cultural battle against wellness trends, preferring to let people believe what they want as long as it isn’t directly killing them.

The Reality of the “Viral Sharing Power”

The Disparity: While alternative health advocates outnumber skeptics in raw volume and content creation—churning out high-yield, emotionally comforting narratives—the pro-science corrections achieve highly concentrated “viral bursts.”

When a prominent alternative health claim is cleanly and definitively debunked by data, it provides a highly shareable, “gotcha” piece of content for the large, silent neutral majority and the highly active skeptic network. A data-driven correction acts as a high-utility intellectual tool, allowing regular people to cut through multi-million dollar wellness marketing, which is why a single well-structured critique can match or outpace the reach of thousands of individual wellness posts.

______________________

I know, there are good reasons for being cautious about such AI analyses. Yet, unless someone can point me to more reliable data, I will go with this one – not least because it coincides with my own experience and also because I quite like its findings.

I came across an interesting paper entitled “The Ethics of Tawas and Other Rituals in Medical Practices“. Here is its abstract:

Rituals in medical practice have either been seen as an anthropological aspect of current biomedical processes or as a pre-scientific aspect of complementary and alternative medicine (CAM). In either tendency, the literature has since failed to account for these rituals as rituals—conveyors of meaning, expressions of identity, and even as a rite of passage from illness to wellness. As an alternative to current discussions, this paper presents the case study of tawas, a diagnostic ritual from Philippine traditional medicine that determines personalistic and mystical causes of illnesses. As a non-intrusive procedure, tawas involves incantations and some ritual objects, e.g., rice, candle, axe, etc., that do not pose any direct harm nor benefit to the patient. While complete reliance on tawas at the expense of proper medical procedures could harm patients, the very ritual of tawas itself occupies a limbo within non-beneficence and non-maleficence. Following a Wittgensteinian perspective of treating rituals as meaning-laden human activities, this paper argues that rituals like tawas, much like other rituals embedded in biomedical practices, should be understood as rituals and not as empirical cures, thereby allowing their tolerance in medical practice in general.

The author seems to advocate for the cultural integration of traditional practices like tawas into a broader medical framework. They categorize tawas not as a physiological intervention, but define it as a conveyor of meaning.  By addressing the “meaning-laden” aspect of illness, the ritual may address the psychological and social dimensions of a patient’s health, even if it has no effect on their physical pathology.

It is claimed that, since tawas involves non-intrusive objects (candles, rice), it is physically benign. At the same time it is acknowledged that “complete reliance” on tawas could harm patients. From a clinical safety standpoint, the “limbo” is only maintained if the ritual is strictly adjunctive rather than alternative.

The text uses a Wittgensteinian perspective, focusing on rituals as expressions rather than theories. Modern neuroscience suggests that the “ritual” of care—the white coat, the focused attention, the diagnostic process—triggers real neurobiological changes (e.g., dopamine and endorphin release). Aacknowledging the symbolic healing power that rituals have on patient anxiety and the “meaning response,” which can objectively improve health outcomes by reducing cortisol and stress.

The author identifies tawas as a diagnostic ritual which might well be the most contentious point. In science, a “diagnosis” must be reliable and valid. Tawas clearly fails the scientific criteria for validity. The author’s defence is that tawas shouldn’t be judged by those criteria at all. While this might be philosophically sound, in a clinical setting, a “mystical diagnosis” must conflict with a biological one, potentially leading to patient non-compliance with life-saving treatments.

This study was conducted to determine the effect of Reiki performed on children with leukemia between the ages of 5-7 years on pain, vital signs, oxygen saturation, and quality of life. It was a double-blind, pre-test-post-test randomized controlled experimental study. The research sample consisted of 66 children with leukemia aged 5-7 years who were hospitalized in pediatric oncology wards of a university hospital between December 2020 and November 2021. The balanced block randomization method was used for randomization. The data were collected using Information Form, Wong-Baker FACES Pain Scale (W-BPS), Vital Signs Follow-up Form, The Pediatric Quality of Life Inventory (PedsQL) 3.0 Cancer Module. Reiki was performed to the Reiki group for 20-30 min once per day, for 3 consecutive days and pseudo-Reiki was applied to the pseudo-Reiki group by an independent nurse during the same application period.

There was no statistically significant difference in vital signs (heart rate, respiratory rate, body temperature) and SpO2 values among the groups (p > 0.05). However, both children’s and mothers’ evaluations on days 1, 2, and 3 after the intervention showed that pain scores in the Reiki group were significantly lower than in the pseudo-Reiki and control groups (p < 0.001), and quality of life was significantly higher (child:p < 0.001; mother:p < 0.01) compared to the pseudo-Reiki and control groups.

The authors concluded that Reiki did not affect the vital signs of the children but was effective in reducing pain and increasing the quality of life compared with the pseudo Reiki and control groups. It is recommended that Reiki therapy be used in addition to medical treatment to reduce pain and improve quality of life in children with leukemia aged 5-7 years.

The whole point of having a control group receiving pseudo-Reiki is to control for placebo effects. For this purpose, it is necessary to fool the patients well and make sure that they are unable to tell Reiki from pseudo-Reiki. I would guess – I have no aceess to the full paper – that this was not the case in this study. If I am correct, the positive outcome is likely to be due to expectation of a positive healing effect and unrelated to any specific effect of Reiki.

In any case, it is irresponsible nonsense to recommend Reiki – or any therapy – on the basis of just one positive study. For that one would need several independent confirmations with  high quality studies that firmly establish a cause effect relationship. The current study does not fall into that category, and I am not aware of a single trial that does.

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.

Recent statements concerning US pharmaceutical pricing have drawn renewed attention to an entirely new horizon in mathematics. The method, associated with remarks by Donald Trump and repeated by several of his sycophants, departs from standard arithmetic in a manner that is rhetorically vigorous but mathematically ridiculous.

Percentage change is defined relative to a single, clearly specified baseline. A decrease from $600 to $100 is therefore calculated as (600-100)/600×100 = 83.3%. In other words, the price falls by 83.3% relative to the original $600 price. This is the method used in economics, finance, accounting, retail pricing, and presumably even by the secondary-school mathematics teachers who attempted to educate Trump.

However, the new alternative math proceeds differently. It implicitly combines two distinct operations: first, the increase from $100 to $600, correctly described as a 500% rise when measured against the initial $100; and second, the subsequent decrease from $600 back to $100. Rather than evaluating this decrease against the higher price, however, the method appears to retain the earlier, lower baseline, thereby generating a claim of a “600% saving.” The arithmetic equivalent of moving the goalposts and then declaring victory by an even larger margin.

Within standard mathematics, this shift in baseline is not permissible. Percentage changes are inherently asymmetric because they depend entirely on the reference point selected. The same absolute difference – in this case, $500 –  produces different percentage values depending on whether it is measured relative to $100 or $600. This is not a technical loophole but the entire point of percentages.

The problem with this approach becomes clearer if one follows it to its logical conclusion. Under standard arithmetic, a 100% price reduction means the price has fallen all the way to zero: a $100 product reduced by 100% costs nothing. A reduction greater than 100% would therefore produce a negative price, meaning the seller would have to pay the customer to accept the product. If one claims that a fall from $600 to $100 represents a 600% decrease, the numbers cease to correspond to any coherent pricing system. The calculation implies that prices can fall not merely to zero, but to values several times smaller than zero.

The attraction of the Trump method is easy to understand. By selecting whichever baseline produces the largest possible percentage, the resulting figure acquires an air of spectacular achievement. It transforms an already substantial price reduction into something approaching numerical performance art.

Trump’s alternative arithmetic therefore succeeds in generating impressively large numbers by abandoning the one feature percentages require most: consistency. The result is as unsound as most things about Trump. Yet it seems rhetorically effective – particularly with “low IQ people”, as Trump likes to call his followers.

In other words, by cherry-picking the baseline for maximum impact, the Trump method turns an already solid 83% cut into a sensational “600% savings”. It sacrifices precision for hype – effective populism perhaps, poor math for sure!

None of this would be worth mentioning, of course, if it were the only incident where Trump misleads his public. Sadly, he is telling multiple and often much more consequential untruths on a daily basis.

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.

 

When a top journal like PNAS (Procedings of the Nationsl Academy of Science) publishes an article entitled “What’s the science behind acupuncture?“, I must take notice. Here is my take on the (sadly disappointing) effort:

My very short summary of the paper (I do encourange my readers to read it in full)

The article starts from the premise that acupuncture is proven to work, an assumption that – as we will see in a minute – is not based on sound evidence. It describes the evolution of acupuncture from a traditional practice rooted in ancient concepts like “qi” and “meridians” to a modern medical treatment increasingly validated by science. It argues that practitioners like Min Chen are today able to provide evidence-based explanations for their work. While early clinical trials were plagued by the “sham” acupuncture paradox, the text argues that more recent, rigorous studies and technological projects are bridging the gap between Eastern philosophy and evidence-based medicine, suggesting that acupuncture’s effects are physiological realities rather than mere placebo.

My concerns of the paper

The article attempts to bridge the gap between Traditional Chinese Medicine (TCM) and conventional medicine suggesting that several anatomical discoveries “correspond” to ancient meridians. This, however, is a post hoc ergo propter hoc fallacy. Finding a morphological structure (e.g. fascia) and claiming it represents the meridian system ignores that meridians were conceptualized as functional energetic conduits, not anatomical vessels. Citing an 80% overlap between acupoints and connective tissue planes lacks specificity. Given the ubiquity of connective tissue in the human frame, any randomized point on the body would likely “overlap” with a tissue plane, rendering the “meridian” map a possible exercise in pattern-seeking rather than anatomical discovery.

The paper acknowledges the “most puzzling” finding that sham acupuncture often produces results comparable to “true” acupuncture. This, it would seem to me, invalidates the foundational TCM theory of specific “acupoints” and “meridians” is invalidated. Yet, the article suggests that sham acupuncture is “not a true placebo” because it also triggers biological pathways. If needling anywhere produces an effect, acupuncture is merely a generalized, non-specific neuro-modulatory stimulus.

The article quotes Chen on “harmonizing organ functions” and “regulating qi” as well as researchers referring to “fibroblast activation” and “vagus nerve stimulation”. The author seems to consider both to be true; yet they seem mutually exclusive. Translating  metaphysical concepts into  physical phenomena does not “validate” the original theory but merely replaces it.

The article employs the opioid crisis to justify the rise of acupuncture. Yes, the need for non-pharmacological pain management is urgent, but clinical necessity does not equate to scientific validity. The text quotes the “lasting benefits” observed in some meta-analyses without discussing the often fatal flaws in these papers. Furthermore, it fails to cite the substantial body of evidence suggesting that acupuncture is not effective. Moreover, it hardly mentions the small effect sizes and hence limited clinical usefulness found in the positive studies.

The final section of the paper essentially rebrands acupuncture as “bioelectronic medicine”. If its mechanism of action is purely the electrical stimulation of the vagus nerve or the release of endogenous opioids, then the TCM concepts are all but superfluous. If a cheap and wearable TENS unit is more or less equivalent, the “meridian” and “qi” myths are obsolete.

In summary, the paper reads, I fear, only marginally better than a Chinese government promotional text – most disappointing for an article published in a journal of high standing. It attempts to preserve the cultural prestige of TCM while stripping it of its internal logic in order to make it compatible with science. For acupuncture to gain a true “scientific footing”, research must, in my view, move beyond finding “tantalizing” correlations. It should address fundamental problems, e.g.:

  • As long as we have no convincing proof that acupuncture works beyond placebo, discussions about its mechanisms are futile.
  • If qi, acupoints and meridians are illusions and irrelevant  for the clinical outcome, then the science is not validating acupuncture but merely re-discovering a well-known non-specific form of peripheral nerve stimulation.
