critical thinking
THE SUN (…yes, I know! …) reported last Sunday that figures from 20 trusts show they forked out for questionable treatments for more than 3,000 patients. Treatments also including acupuncture and aromatherapy cost a total of £269,000. If the figure is applied across all 120-plus trusts the true cost could be well over £1.5 million. Hull University Teaching Hospitals spent the most, at £170,000.
The Taxpayers’ Alliance, which did the analysis, said: “With long waiting lists, quack remedies cannot be allowed to divert precious resources.” Alternative medicine expert Dr Edzard Ernst said: “The NHS often uses complementary medicine rarely based on good evidence but on lobbying of proponents of quackery.”

Whenever I am asked by journalists to provide a critical comment on so-called alternative medicine (SCAM), I have mixed feelings. On the one hand, I find it important to get a rational message out, particularly into certain papers. On the other hand, I dread what they might do with my comment, particularly certain papers. If I had £5 for every time I have been misquoted, I could probably buy a decent second-hand car! This is why I nowadays tend to give my comments in writing via e-mail.
To my relief, THE SUN quoted me (almost) correctly. Almost correctly, but not fully! Here is the question I was asked to respond to: NHS statistics show the health service spending more than £250,000 on complementary and alternative medicines last year. Do you think this is a sensible use of NHS funding? Are the benefits well proven enough to spend taxpayer money on these therapies?
And here is my attempt to respond in a concise way that SUN readers might still understand:
Complementary medicine is an umbrella term for more than 400 treatments and diagnostic techniques. Some of them work but many don’t; some are safe but many are not. If the NHS would spend £250000 – a tiny amount considering the overall expenditure in the NHS – on those few that do generate more good than harm, all might be fine. The problem, I think, is that the NHS currently uses complementary medicine rarely based on good evidence but often based on the lobbying of influential proponents of quackery.
As you see, it is good to deal with requests from journalists in writing!
This pragmatic, randomised controlled trial was conducted between September 2018 and February 2021 and compared the difference between primary homoeopathic and conventional paediatric care in treating acute illnesses in children in their first 24 months of life. It was conducted at the Central Council for Research in Homoeopathy (CCRH) Collaborative Outpatient Department of the Jeeyar Integrated Medical Services (JIMS) Hospital in Telangana, India, a tertiary-care hospital that provides integrated patient-centric care, using homoeopathy and Ayurveda alongside conventional medicine.
One hundred eight Indian singleton newborns delivered at 37 to 42 weeks gestation were randomised at birth (1:1) to receive either homoeopathic or conventional primary care for any acute illness over the study period. In the homoeopathic group, conventional medical treatment was added when medically indicated. Clinicians and parents were unblinded.
The study’s primary outcome was a comparison of the number of sick days due to an acute illness experienced during the first 24 months of life by children receiving homoeopathic vs. conventional treatment. Sick days were defined as days with any acute illness (febrile or afebrile) reported by the parent and confirmed by the physician. Febrile illness was recorded when body temperature, measured via the ear canal, exceeded 37.5 °C.
The secondary outcomes compared were as follows:
- The number of sickness episodes, defined as illness events (febrile or afebrile), reported by the parent and confirmed by the physician.
- Number of respiratory illness episodes and days during the 24 months. Respiratory illnesses included infections in any part of the respiratory tract (nose, middle ear, pharynx, larynx, trachea, bronchi, bronchioles, and lungs) .
- Number of diarrhoeal episodes and days during the 24 months. Diarrhoea was defined as three or more episodes of watery stool/day, with or without vomiting, with indications of dehydration, weight loss, or defective weight gain.
- Anthropometric data included weight (measured by electronic scales to the nearest 5 g), height (measured in triplicate to the nearest 0.2 cm using a rigid-length board), head circumference (HC), and mid-upper arm circumference (MUAC) (measured with a standard measuring tape to the nearest 0.2 cm every 3 months until the 24th month).
- Developmental status was evaluated according to the Developmental Assessment Scales for Indian Infants (DASII) every 6 months from the age of 6 to 24 months.
- Direct cost of treatment for illnesses during the 24 months, including cost of medications, inpatient admissions, investigations, supplements, and treatment outside the hospital facility or study site (consultation and/or medicines).
- Use of antibiotics during the 24 months, defined as the number of antibiotic episodes during the study.
- Mortality: death due to any acute illness episode.
The results show that children in the homoeopathic group experienced significantly fewer sick days than those in the conventional group (RR: 0.37, 95% CI: 0.24-0.58; p < 0.001), with correspondingly fewer sickness episodes (RR: 0.53, 95% CI: 0.32-0.87; p = .013), as well as fewer respiratory illnesses over the 24-month period. They were taller (F (1, 97) = 8.92, p = .004, partial eta squared = 0.84) but not heavier than their conventionally treated counterparts. They required fewer antibiotics, and their treatment cost was lower.
The authors concluded that homoeopathy, using conventional medicine as a safety backdrop, was more effective than conventional treatment in preventing sick days, sickness episodes, and respiratory illnesses in the first 24 months of life. It necessitated fewer antibiotics and its overall cost was lower. This study supports homoeopathy, using conventional medicine as a safety backdrop, as a safe and cost-effective primary care modality during the first 2 years of life.
Here we have another study designed in such a way that a positive result was inevitable. Both groups of children received the necessary conventional care and treatment. The verum group received homeopathy in addition. There were no placebo controls and everyone knew which child belonged to which group. Thus the verum group benefitted from a poweful placebo effect, while the control group experience disappointment over not receiving the extra attention and medication. One might argue that newborn babies cannot experience a placebo response nor disappointment. Yet, one would be wrong and in need of reading up about placebo effects by proxy.
A+B is always more than B alone
To boldy entitle the paper ‘Homoeopathy vs. conventional primary care in children during the first 24 months of life’ and state that the trial aimed to “compared the difference between primary homoeopathic and conventional paediatric care in treating acute illnesses in children in their first 24 months of life”, is as close to scientific misconduct as one can get, in my view!
Yet again, I might ask: what do we call a study that is designed in such a way that a positive result was inevitable?
- misleading?
- waste of resources?
- unethical?
- fraud?
And again, I let you decide.
PS
I feel disappointed that a decent journal published this paper without even a critical comment!
Chiropractic is a complementary medicine that has been growing increasingly in different countries over recent decades. It addresses the prevention, diagnosis and treatment of the neuromusculoskeletal system disorders and their effects on the whole body health.
This review aimed to evaluate the effectiveness of chiropractic in the treatment of different diseases. To gather data, scientific electronic databases, such as Cochrane, Medline, Google Scholar, and Scirus were searched and all systematic reviews in the field of chiropractic were obtained. Reviews were included if they were specifically concerned with the effectiveness of chiropractic treatment, included evidence from at least one clinical trial, included randomized studies and focused on a specific disease. The articles were excluded if:
- – they were concerned with a combination of chiropractic and other treatments (not specifically chiropractic treatment);
- – they lacked at least one clinical trial;
- – they lacked at least one randomized study;
- – and they studied chiropractic in the treatment of multiple diseases.
The research data including the article’s first author’s name, type of disease, intervention type, number and types of research used, meta-analysis, number of participants, and overall results of the study, were extracted, studied and analyzed.
Totally, 23 chiropractic systematic reviews were found, and 11 articles met the defined criteria. The results showed the influence of chiropractic on improvement of neck pain, shoulder and neck trigger points, and sport injuries. In the cases of asthma, infant colic, autism spectrum disorder, gastrointestinal problems, fibromyalgia, back pain and carpal tunnel syndrome, there was no conclusive scientific evidence. There is heterogeneity in some of the studies and also limited number of clinical trials in the assessed systematic reviews. Thus, conducting comprehensive studies based on more reliable study designs are highly recommended.
The authors stressed that three points should be emphasized. Firstly, there is a discrepancy between the development of chiropractic in different countries of the world and the quality and quantity of studies regarding the effectiveness and safety of chiropractic in treatment of diseases. Secondly, some of the systematic reviews regarding the effectiveness of chiropractic in treatment of diseases had a minimum quality of research methodology and were not useful for evaluation. Some of the excluded articles are examples of this problem. Finally, a limited number of studies (11 systematic review articles and 10 diseases) had the required criteria and were assessed in the study.
Assessment and analysis of the studies showed the impact of chiropractic on improvement of some upper extremity conditions including shoulder and neck trigger points, neck pain and sport injuries. In the case of asthma, infant colic and other studied diseases, further clinical trials with larger sample sizes and high quality research methodology are recommended.
So, is chiroprctic of proven effectiveness for any disease?
The conditions for which there is tentatively positive evidence (btw: most rely on my research!!!) are arguably not diseases but symptoms of undelying conditions. Therefore, the answer to my question above is:
NO.
In China, acupuncture has been employed as an adjunctive therapy for coronavirus disease 2019 (COVID-19). Press needle acupuncture is a special type of acupuncture that provides prolonged stimulation to acupuncture points. This study assessed the effectiveness of integrating press needles alongside pharmacologic treatment in patients with mild-to-moderate COVID-19.
Patients hospitalized with mild-to-moderate COVID-19 symptoms between December 2022 and January 2023 were included in the study. The enrolled patients were randomly assigned to receive:
- pharmacologic treatment alone (control group),
- or both pharmacologic treatment and press needle acupuncture (intervention group).
Patients were evaluated for clinical outcomes, including symptom scores, deterioration rates, fever durations, and nucleic acid test results. The patients’ complete blood count and C-reactive protein levels were also analyzed using venous blood samples both before and after treatment.
Both groups exhibited a reduction in clinical symptom scores, but symptoms regressed faster in the intervention group. Nucleic acid test negativity was achieved faster in the intervention group than in the control group. The intervention group also had a lower deterioration rate. Furthermore, the increase in the lymphocyte count and decrease in C-reactive protein levels following treatment were more pronounced in the intervention group than in the control group.
The authors concluded that this study suggests that utilizing press needle acupuncture as an adjunct to pharmacologic treatment can be effective in patients with mild-to-moderate COVID-19 symptoms.
To understand this study better, we need to comprehend the nature of the therapeutic ritual. This is how the authors describe it:
For each session, press needles were inserted into acupoints and kept in place for approximately 24 hours. Only 1 side of the body (left or right) was treated in each session. The following day, press needles were removed from 1 side of the body, and new press needles were placed on acupoints on the other side of the body. Press needle acupuncture was performed by a qualified physician who had completed comprehensive acupuncture training. By contrast, patients in the control group solely received daily pharmacologic treatment, such as Lianhua Qingwen granules, with ibuprofen added as needed for fever management. Study participants were instructed to notify researchers of the appearance of clinical symptoms, and they were prohibited from participating in other studies during the trial period.
So, neither the patients nor the therapists were blinded. To call such a study “single-blind” is a bit odd! And are we really supposed to assume that the verum therapy did not generate placebo effects?
What we have here, I fear, is a classic example of a study designed such that it cannot possibly produce a negative result. It followed the A+B versus B design and employed a treatment that is bound to generate a sizable placebo response. What is even worse, the authors do discuss the limitations of their study but ignore the ‘elefant in the room’: ” this study had several limitations. The sample size was modest, and basic randomization was used without stratification based on comorbidities, which could have introduced bias.”
What do we call a study that cannot possibly produce a negative result?
- A waste of resources?
- Fraud?
- Misleading?
- Naive?
- Unethical?
I leave the answer to you.
The objective of the present double-blind, randomized, placebo-controlled, feasibility trial was to identify the effects of individualized homeopathic medicinal products (IHMPs) against placebos in post-COVID-19 conditions. Sixty participants with post-COVID-19 conditions were randomised into either:
- group verum (n = 30; IHMPs plus concomitant care),
- group control (n = 30; placebos plus concomitant care).
Feasibility issues; primary—post-COVID-19 symptoms checklist; secondary—Measure Yourself Medical Outcomes Profile version 2 (MYMOP-2); all of them were measured at baseline, and monthly intervals, up to 3 months. The intention-to-treat sample was analyzed; group differences were reported using descriptive statistics: means, 95% confidence intervals (CIs), and between group effect sizes (Cohen’s d).
Feasibility concerns showed promise; recruitment, retention, and attrition rates were 34.2%, 95%, and 5%, respectively. Group differences in both primary and secondary outcomes favored IHMPs against placebos: symptoms checklist score mean difference after 3 months: −4.2, 95% CI −4.9 to −3.4, d = 2.854 and MYMOP-2 mean difference after 3 months: −2.2, 95% CI −2.8 to −1.7, d = 2.082, respectively. Natrum muriaticum (11.7%), Pulsatilla nigricans (10%), Rhus toxicodendron (8.3%), and Calcarea carbonica (8.3%) were the most frequently prescribed remedies.
The authors concluded that IHMPs produced better results than placebos in reducing symptoms checklist scores and MYMOP-2 scores in the treatment of post-COVID-19 conditions. Definitive trials are warranted to confirm the findings.
A feasibility study (the authors employ this term repeatedly) has – as I have often pointed out – the purpose of testing whether a trial disign, set-up, etc. is FEASIBLE. It is not meant to report other outcome data.
Why?
Mainly because such studies are far too underpowered for generating reliable results!
This means that the present findings can be ignored. They are most likely caused by chance.
Why are they published anyway, and why could the authors find a journal that goes along with such nonsense?
Are they too stupid or are they biased or both?
The nature of the journal might provide a hint for answering these questions (J Integr Complement Med), and so does the list of authors and their affiliations:
- 1Department of Organon of Medicine and Homoeopathic Philosophy, D. N. De Homoeopathic Medical College and Hospital, Govt. of West Bengal, Kolkata, India.

I rest my case.
An article entitled “The use of ayurvedic medicine in the management of hypertension” was recently published in the ‘Journal of Ayurveda and Naturopathy’ (no, I did not know either that this journal existed). Here I show you merely its conclusion, but encourage you to read the entire paper.
Hypertension, a significant risk factor for cardiovascular diseases, necessitates effective and sustainable management strategies. Ayurveda, with its holistic approach, offers a comprehensive framework for managing hypertension by addressing the underlying dosha imbalances through dietary and lifestyle modifications, herbal formulations, and therapeutic procedures. This review has highlighted the
efficacy of various Ayurvedic interventions, including the use of specific herbs like Ashwagandha, Arjuna, Brahmi, Gokshura, and Sarpagandha, which have demonstrated significant benefits in reducing blood pressure and improving overall health. Panchakarma therapies such as Virechana, Basti, Nasya, and Shirodhara have also been shown to detoxify the body, restore balance, and promote
long-term well-being.
Integrating Ayurvedic practices with modern medical approaches can enhance treatment outcomes, offering a more personalized and holistic approach to hypertension management. This synergy can potentially reduce the reliance on pharmaceuticals, minimize side effects, and improve patient compliance and quality of life. Future research should focus on rigorous clinical trials and the standardization of Ayurvedic formulations to further validate their efficacy and facilitate their integration into mainstream healthcare.
By embracing the principles of Ayurveda, individuals can achieve better control over hypertension, reduce the risk of associated complications, and enhance their overall health and well-being. This comprehensive approach not only addresses the symptoms but also tackles the root causes, promoting a sustainable and balanced lifestyle.

Not only does the author, Dr. Zafar Siddiqa (from the Faculty of Natural Medicine and Holistic Sciences, Rajshahi Holistic Health College, Rajshahi, Bangladesh) re-write the current knowledge of hypertonology, he also provides no evidence for any of the far-reaching statements he makes in this paper. In particular, he cites no rigorous studies that “highlighted the efficacy of various Ayurvedic interventions” (most likely because such studies do not exist).
The autor is correct in the 1st sentence of his conclusion: “Hypertension, a significant risk factor for cardiovascular diseases, necessitates effective and sustainable management strategies”. But he is wrong in almost everything else! Because hypertension is such an important risk factor for stroke and ischaemic heart disease, we MUST treat it effectively.
Today, we fortunately have many conventional treatments that control hypertension well and with no or just minimal adverse effects. Advocating quackary or unproven therapies for managing hypertension is thus deeply unethical. It could contribute to the premature deaths of millions. I thus fear that the ‘Faculty of Natural Medicine and Holistic Sciences, Rajshahi Holistic Health College’ is in urgent need of taking a few courses in proper science and medical ethics.
If I remember correctly, I was – some 20 years ago – a founding member of the editorial board of the journal Evidence-Based Complementary and Alternative Medicine (EBCAM). I also published several papers there, but eventually I became concerned about what seemed to be going on at the journal (it seemed a money-making scam to me) and withdrew my cooperation. Since then, I have repeatedly posted on this blog about this strange journal, e.g.:
- EBCAM: an alt med journal that puzzles me a great deal
- Some alternative medicine journals should be de-listed
- Fraud and greed can cause enormous harm
Yesterday,I came across this announcement by John Wiley & Sons, now the publisher of EBCAM:
Evidence-Based Complementary and Alternative Medicine ceased publishing as of September 2024.
Trying to find out more about this surprising action, I found this little note:
John Wiley & Sons, a global publication house with revenues north of $2 billion, announced on May 19, 2024, that it was closing 19 journals it acquired as part of its 2021 purchase of Egypt-based Hindawi publishing company, citing large-scale research fraud.
Next, I went on to Medline and saw that EBCAM had to retract 1 497 (!) of its papers.
That amount of retractions must be a world record!
I thus understand that the journal was no longer tenable. But what exactly did happen? What brought about the decision to cease publication?
I have no idea (various searches for answers were unsuccessful) and would be most grateful, if someone in the know could fill me in.
- complement conventional and supportive care,
- be complemented with other supportive therapies,
- substitute for supportive drugs,
- replace other supportive therapies,
- not be suitable to replace all supportive therapies,
- be the only supportive option available in some situations.
While the evidence base on web-based cancer misinformation continues to develop, relatively little is known about the extent of such information on the world’s largest e-commerce website, Amazon. Multiple media reports indicate that Amazon may host on its platform questionable cancer-related products for sale, such as books on purported cancer cures. This context suggests an urgent need to evaluate Amazon.com for cancer misinformation.
This study sought to
- (1) examine to what extent are misleading cancer cure books for sale on Amazon.com’
- (2) determine how cancer cure books on Amazon.com provide misleading cancer information.
The investigators searched “cancer cure” on Amazon.com and retrieved the top 1000 English-language book search results. They reviewed the books’ descriptions and titles to determine whether the books provided misleading cancer cure or treatment information. They considered a book to be misleading if it suggested scientifically unsupported cancer treatment approaches to cure or meaningfully treat cancer. Among books coded as misleading, they conducted an inductive latent thematic analysis to determine the informational value the books sought to offer.
Nearly half (494/1000, 49.4%) of the sampled “cancer cure” books for sale on Amazon.com appeared to contain misleading cancer treatment and cure information. Overall, 17 (51.5%) out of 33 Amazon.com results pages had 50% or more of the books coded as misleading. The first search result page had the highest percentage of misleading books (23/33, 69.7%). Misleading books (n=494) contained eight themes:
- (1) claims of efficacious cancer cure strategies (n=451, 91.3%),
- (2) oversimplifying cancer and cancer treatment (n=194, 39.3%),
- (3) falsely justifying ineffective treatments as science based (n=189, 38.3%),
- (4) discrediting conventional cancer treatments (n=169, 34.2%),
- (5) finding the true cause of cancer (n=133, 26.9%),
- (6) homogenizing cancer (n=132, 26.7%),
- (7) discovery of new cancer treatments (n=119, 24.1%),
- (8) cancer cure suppression (n=82, 16.6%).
The authors concluded that the results demonstrate that misleading cancer cure books are for sale, visible, and prevalent on Amazon.com, with prominence in initial search hits. These misleading books for sale on Amazon can be conceived of as forming part of a wider, cross-platform, web-based information environment in which misleading cancer cures are often given prominence. Our results suggest that greater enforcement is needed from Amazon and that cancer-focused organizations should engage in preemptive misinformation debunking.
This is an excellent paper that is long overdue. The plethora of dangerous books on so-called alternative medicine (SCAM) targeted at lay people is nothing short of a scandal. It was high time that we expose it, because it kills vulnerable patients. It is difficult, if not impossible, to quantify the damage done by such books but I am sure it runs in the thousands.
I have been aware of this scandal for a long time, in fact, it was the main motivation for publishing my own book on the subject. Obviously, it is not much more than a drop in the ocean.
Tragically, this scandal is not confined to just cancer. It relates to all potentially serious conditions. What could be more despicable and unethical than earning money through making desperately ill patients suffer? As the authors point out, Amazon urgently needs to address this problem. Failing this, Amazon should be legally held responsible, in my view.
Approximately 30% of children diagnosed with attention-deficit/hyperactivity disorder (ADHD), the most prevalent mental health disorder in children worldwide, do not respond to conventional pharmaceutical treatments. Previous studies of homeopathic treatment for ADHD have been inconclusive. The objectives of this randomized double-blind placebo-controlled clinical trial were to determine if there
- (a) is an overall effect of homeopathic treatment (homeopathic medicines plus consultation) in the treatment of ADHD;
- (b) are any specific effects the homeopathic consultation alone in the treatment of ADHD;
- (c) are any specific effects of homeopathic medicines in the treatment of ADHD.
Children aged 6-16 years diagnosed with ADHD were randomized to one of three arms:
- Arm 1 (Remedy and Consultation);
- Arm 2 (Placebo and Consultation);
- Arm 3 (Usual Care).
The primary outcome was the change of CGI-P T score between baseline and 28 weeks.
There was an improvement in ADHD symptoms as measured by the Conner 3 Global Index-Parent T-score in the two groups (Arms 1 and 2) that received consultations with a homeopathic practitioner when compared with the usual care control group (Arm 3). Parents of the children in the study who received homeopathic consultations (Arms 1 and 2) also reported greater coping efficacy compared with those receiving usual care (Arm 3). There was no difference in adverse events among the three study arms.
The authors concluded that, in this study, homeopathic consultations provided over 8 months with the use of homeopathic remedy was associated with a decrease in ADHD symptoms in children aging 6-16 years when compared with usual treatment alone. Children treated with homeopathic consultations and placebo experienced a similar decrease in ADHD symptoms; however, this finding did not reach statistical significance when correcting for multiple comparisons. Homeopathic remedies in and of themselves were not associated with any change in ADHD symptoms.
This is an interesting study. It – yet again! – confirms that the effects observed after homeopathic treatments are not due to the remedie but are caused by the interaction with the homeopath. To put it more clearly:
HOMEOPATHIC REMEDIES HAVE NO SPECIFIC EFFECTS; ANY BENEFITS ARE DUE TO THE EFFECTS OF THE THERAPEUTIC ENCOUNTER AND OTHER NON-SPECIFIC EFFECTS.
