Current interventions for posttraumatic stress disorder (PTSD) are efficacious, yet effectiveness may be limited by adverse effects and high withdrawal rates. Acupuncture is an intervention with some positive preliminary but methodologically flawed data for PTSD.  Therefore a new study compared verum acupuncture with sham acupuncture (minimal needling) on clinical and physiological outcomes.

This was a 2-arm, parallel-group, prospective blinded randomized clinical trial hypothesizing superiority of verum to sham acupuncture. The study was conducted at a single outpatient-based site, the Tibor Rubin VA Medical Center in Long Beach, California, with recruitment from April 2018 to May 2022, followed by a 15-week treatment period. Following exclusion for characteristics that are known PTSD treatment confounds, might affect biological assessment, indicate past nonadherence or treatment resistance, or indicate risk of harm, 93 treatment-seeking combat veterans with PTSD aged 18 to 55 years were allocated to group by adaptive randomization and 71 participants completed the intervention protocols.

Verum and sham were provided as 1-hour sessions, twice weekly, and participants were given 15 weeks to complete up to 24 sessions. The primary outcome was pretreatment to posttreatment change in PTSD symptom severity on the Clinician-Administered PTSD Scale-5 (CAPS-5). The secondary outcome was pretreatment to posttreatment change in fear-conditioned extinction, assessed by fear-potentiated startle response. Outcomes were assessed at pretreatment, midtreatment, and posttreatment. General linear models comparing within- and between-group were analyzed in both intention-to-treat (ITT) and treatment-completed models.

A total of 85 male and 8 female veterans (mean [SD] age, 39.2 [8.5] years) were randomized. There was a large treatment effect of verum (Cohen d, 1.17), a moderate effect of sham (d, 0.67), and a moderate between-group effect favoring verum (mean [SD] Δ, 7.1 [11.8]; t90 = 2.87, d, 0.63; P = .005) in the intention-to-treat analysis. The effect pattern was similar in the treatment-completed analysis: verum d, 1.53; sham d, 0.86; between-group mean (SD) Δ, 7.4 (11.7); t69 = 2.64; d, 0.63; P = .01). There was a significant pretreatment to posttreatment reduction of fear-potentiated startle during extinction (ie, better fear extinction) in the verum but not the sham group and a significant correlation (r = 0.31) between symptom reduction and fear extinction. Withdrawal rates were low.

The authors concluded that the acupuncture intervention used in this study was clinically efficacious and favorably affected the psychobiology of PTSD in combat veterans. These data build on extant literature and suggest that clinical implementation of acupuncture for PTSD, along with further research about comparative efficacy, durability, and mechanisms of effects, is warranted.

I am not sure that the authors’ enthusiastic verdict is correct. Its lead author was even quoted stating that his study, which used improved controls, was needed to “definitively” support acupuncture for PTSD. He noted that “acupuncture ought to be considered a potential first-line treatment for PTSD.”

While the study is an improvement on the previous research in this area, it is by no means compelling. My main point of criticism is the nature of the sham acupuncture. Such controls are used to account for placebo effects which, of course, can be considerable in the case of acupuncture.

For this concept to work adequately, the patient and the therapist need to be blinded. In the case of acupuncture, therapist blinding is difficult (but not impossible). In this study, therepists were not blinded. Thus they could have influenced the outcome by verbal and non-verbal clues given to the patient. As acupuncturists inevitably have an interest in the positive result of their study, this effect seems inevitable to me.

More important, however, is the adequate blinding of the patient. In this study, it was attempted by using shallow needling as a sham intervention. Yet, shallow needling can easily distinguished from real acupuncture by the patient. At the very least, patients should be asked what treatment – sham or real – they thought they had received. This did not happen, and we therefore might assume that the effect of patient de-blinding – combined with the confounder described above – was sufficient to bring about the relatively small effect sizes observed by the authors.

One might argue that this does not really matter; all that counts is to alleviate the suffering of the patients, never mind by what mechanism. I think, this would be erroneous. It matters because, if acupuncture itself is ineffective (which I suggest), settling for acupuncture as a first line therapy for PTSD is in nobody’s interest and a disservice to severely suffering patients. It would inhibit meaningful research aimed at finding an optimal therapy (one that works beyond placebo) and be a waste of resources.


This study tested whether trigger point acupuncture (TrPA) is beneficial for office workers who have reduced job performance (presenteeism) due to chronic neck and shoulder pain (katakori).

A 4-week single-center randomized clinical trial was conducted on 20 eligible female office workers with chronic neck and shoulder pain of at least 3-month duration. The control group implemented only workplace-recommended presenteeism measures, whereas the intervention group received TrPA up to 4 times per month in addition to the presenteeism measures recommended by each workplace. The major outcome measure was the relative presenteeism score on the World Health Organization Health and Work Performance (WHO-HPQ). The secondary outcome measures were pain intensity (numerical rating scale), absolute presenteeism (WHO-HPQ), anxiety and depression (Hospital Anxiety and Depression Scale; HADS), catastrophic thoughts related to pain (Pain Catastrophizing Scale; PCS), and sleep (Athens Insomnia Scale; AIS).

All 9 cases in the intervention group and 11 cases in the control group were analyzed. TrPA up to 4 times per month reduced the intensity of neck and shoulder pain by 20% (P < .01, d = 1.65) and improved labor productivity (relative presenteeism value) by 0.25 (P < .01, d = 1.33) compared with the control group over 1 month. No significant differences were observed between the 2 groups in terms of absolute presenteeism score, HADS, PCS, or AIS.

The authors concluded that these results suggest that regular intervention with TrPA may be effective in the relative presenteeism score before and after the intervention and the degree of neck and shoulder pain over 28 days compared with the control group.

Sure, TrPA may be effective.

But is it?

I thought the trial was aimed at answering that question!

But it didn’t!

Why not?

Because, as we have discussed ad nauseam on this blog, the A+B versus B study design cannot answer it. On the contrary, it will always generate a positive result without determining whether the treatment or a nonspecific (placebo) effect caused the outcome (which, of course, is the reason why this study design is so popular in SCAM research).

In view of this, I suggest to re-formulate the conclusions as follows:

The study suggests that the researchers were ill-informed when designing it. Therefore, the findings show nothing of value.

Supportive care is often assumed to be beneficial in managing the anxiety symptoms common in patients in sterile hematology unit. The authors of this study hypothesize that personal massage can help the patient, particularly in this isolated setting where physical contact is extremely limited.

The main objective of this study therefore was to show that anxiety could be reduced after a touch-massage performed by a nurse trained in this therapy.

A single-center, randomized, unblinded controlled study in the sterile hematology unit of a French university hospital, validated by an ethics committee. The patients, aged between 18 and 65 years old, and suffering from a serious and progressive hematological pathology, were hospitalized in sterile hematology unit for a minimum of three weeks. They were randomized into either a group receiving 15-minute touch-massage sessions or a control group receiving an equivalent amount of quiet time once a week for three weeks.

In the treated group, anxiety was assessed before and after each touch-massage session, using the State-Trait Anxiety Inventory questionnaire with subscale state (STAI-State). In the control group, anxiety was assessed before and after a 15-minute quiet period. For each patient, the difference in the STAI-State score before and after each session (or period) was calculated, the primary endpoint was based on the average of these three differences. Each patient completed the Rosenberg Self-Esteem Questionnaire before the first session and after the last session.

Sixty-two patients were randomized. Touch-massage significantly decreased patient anxiety: a mean decrease in STAI-State scale score of 10.6 [7.65-13.54] was obtained for the massage group (p ≤ 0.001) compared with the control group. The improvement in self-esteem score was not significant.

The authors concluded that this study provides convincing evidence for integrating touch-massage in the treatment of patients in sterile hematology unit.

I find this conclusion almost touching (pun intended). The wishful thinking of the amateur researchers is almost palpable.

Yes, I mean AMATEUR, despite the fact that, embarrassingly, the authors are affiliated with prestigeous institutions:

  • 1Nantes Université, CHU Nantes, Service Interdisciplinaire Douleur, Soins Palliatifs et de Support, Médecine intégrative, UIC 22, Nantes, F-44000, France.

So, why do I feel that they must be amateurs?

  • Because, if they were not amateurs, they would know that a clinical trial should not aim to show something, but to test something.
  • Also, if they were not amateurs, they would know that perhaps the touch-massage itself had nothing to do with the outcome, but that the attention, sympathy and empathy of a therapist or a placebo effect can generate the observed effect.
  • Lastly, if they were not amateurs, they would not speak of convincing evidence based on a single, small, and flawed study.

After the nationwide huha created by the BBC’s promotion of auriculotherapy and AcuSeeds, it comes as a surprise to learn that, in Kent (UK), the NHS seems to advocate and provide this form of quackery. Here is the text of the patient leaflet:

Kent Community Health, NHS Foundation Trust


This section provides information to patients who might benefit from auriculotherapy, to complement their acupuncture treatment, as part of their chronic pain management plan.

What is auriculotherapy?

In traditional Chinese medicine, the ear is seen as a microsystem representing the entire body. Auricular acupuncture focuses on ear points that may help a wide variety of conditions including pain. Acupuncture points on the ear are stimulated with fine needles or with earseeds and massage (acupressure).

How does it work?

Recent research has shown that auriculotherapy stimulates the release of natural endorphins, the body’s own feel good chemicals, which may help some patients as part of their chronic pain management plan.

What are earseeds?

Earseeds are traditionally small seeds from the Vaccaria plant, but they can also be made from different types of metal or ceramic. Vaccaria earseeds are held in place over auricular points by a small piece of adhesive tape, or plaster. Applying these small and barely noticeable earseeds between acupuncture treatments allows for patient massage of the auricular points. Earseeds may be left in place for up to a week.

Who can use earseeds?

Earseeds are sometimes used by our Chronic Pain Service to prolong the effects of standard acupuncture treatments and may help some patients to self manage their chronic pain.

How can I get the most out my treatment with earseeds?

It is recommended that the earseeds are massaged two to three times a day or when symptoms occur by applying gentle pressure to the earseeds and massaging in small circles.

Will using earseeds cure my chronic pain?

As with any treatment, earseeds are not a cure but they can reduce pain levels for some patients as part of their chronic pain management programme.


What the authors of the leaflet forgot to tell the reader is this:

  • Auriculotherapy is based on ideas that fly in the face of science.
  • The evidence that auriculotherapy works is flimsy, to say the least.
  • The evidence earseeds work is even worse.
  • To arrive at a positive recommendation, the NHS had to heavily indulge in the pseudo-scientific art of cherry-picking.
  • The positive experience that some patients report is due to a placebo response.
  • For whichever condition auriculotherapy is used, there are treatments that are much more adequate.
  • Advocating auriculotherapy is therefore not in the best interest of the patient.
  • Arguably, it is unethical.
  • Definitely, it is not what the NHS should be doing.

I had the rare pleasure to give an interview for the ‘Frankfurter Allgemeine’. As it was, of course, in German, I took the liberty to translate it for my non-German speaking readers:

You have researched so-called alternative medicine over several decades, including homeopathy. What is your conclusion?

We are talking about far more than 400 methods – to draw one conclusion about all of them
is completely impossible. Except perhaps for this one: if something sounds too good to be true, it probably is.

Does this apply to homeopathy?

Highly diluted homeopathic remedies are popular because they have no side-effects. But there is also no effect. They are touted as a panacea. This is certainly not the case, on the contrary, they are
ineffective. And any therapy that is ineffective and promoted as a panacea is also dangerous.

How do you explain the fact that so many people swear by homeopathy?

There are several reasons for this. In Germany, homeopathy has an unbroken tradition, it was, for instance, promoted by the Nazis and later in the Federal Republic of Germany. It has a reputation for being gentle and effective. It might be gentle, but it is certainly not effective. It is also supported by lobby groups such as the manufacturers. And most people who use it don’t even understand what it actually is.

In any case, the placebo effect helps. What’s so bad about that??

Nothing at all, on the contrary: it is to be advocated. When we talk about placebo effects, we subsume many things under this umbrella that do not actually belong to it, such as the extensive, empathetic conversation that homeopaths often have with their patients. Besides, a common cold goes away whether you treat it or not. If you then use homeopathy, you can easily get the impression that it worked. Every good, empathetic doctor tries to maximize the placebo effect. To put it bluntly: you don’t need a placebo to generate a placebo effect. Patients also benefit from it when I give an effective remedy with empathy. In addition they benefit from the specific effect of my therapy, which should make up the lion’s share of the therapeutic response. If I withhold the most important thing I mistreat my patient.

But there are diseases for which there are no good remedies.

I often hear that argument. But there is practically always something we can do that at least
improves symptoms. Otherwise you should also say that instead of lying and recommending homeopathy – and thinking that, although there is nothing in it and it doesn’t work, but the patient, being an idiot, should take it nevertheless. It is unethical to use placebos as much as it is to use homeopathy.

Neurophysiologically, the placebo effect is becoming better and better understood.

The Italian neuroscientist Fabrizio Benedetti in particular has done very good work.  But he also warns that this does not justify the use of homeopathy, for example.

Are there any studies on whether the placebo effect of homeopathy with its esoteric superstructure is greater than that giving just a piece of sugar?

There are analyses of what makes a particularly effective placebo. From this, we can learn that effective therapies in evidence-based medicine must be applied with empathy and sufficient time in order to maximize the ever-present placebo effect. So-called alternative medicine often does this quite well, and we can learn something from it. But the reason is that it often has nothing else. Homeopaths are a serious danger because they see homeopathy as a panacea. If someone has homeopathically treated their cold “successfully” for years and then gets cancer, they might think of turning to homeopathy for their cancer. It sounds crazy, but many homeopaths do offer cancer treatments on the internet, for instance. That sends shivers down my spine.

How should doctors and pharmacists react to the demand for homeopathic remedies?

Pharmacists are not primarily salespeople, they are a medical profession – they have to adhere to ethical guidelines. In this respect, evidence-based information of their clients/patients is very important.

Thomas Benkert, President of the German Federal Chamber of Pharmacists, has stated that he would not be able to stop giving advice if he always had to explain the lack of proof of efficacy.

He should perhaps read up on what his ethical duty to patients is.

What if doctors or pharmacists themselves believe in the effect?

Belief should not play a role, but evidence should.

Are you pleased with Lauterbach’s plan to no longer reimburse homeopathy?

I think it’s a shame that he justifies it by saying it’s ineffective. That is true. But the justification should be that it’s esoteric nonsense and therefore ineffective – and dangerous.

In the end, the Bundestag will decide.

I think Lauterbach has a good chance because things have started to move. Medical associations in Germany have spoken out against the additional designation of homeopathy, for example, and overall the wind has changed considerably.

What is it like in the UK, where you live?

The UK healthcare system, NHS, said goodbye to reimbursement of homeopathy about five years ago, even before France. The pharmacists’ association has distanced itself very clearly from homeopathy. However, most pharmacists still sell the remedies and many continue to support them.

You have also had disputes with the current head of state, King Charles. How did that come about?

A few years ago, he commissioned a paper claiming that so-called alternative medicine could save the British health service a lot of money. I protested against this – Charles accused me of leaking it to The Times before it was published. My university launched an investigation, which eventually found me innocent, but it led to the demise of my department. That caused me to retire two years early.

So Charles managed to close down the only research unit in the world that conducted critical and systematic research into so-called alternative medicine. Most researchers in this field only want to confirm their own prejudices and not disprove hypotheses. This is a serious misunderstanding of how science works. If someone reports only positive results for their favorite therapy in all conditions, something is wrong.

Some people say that homeopathy should not be researched because nothing positive can come out of it anyway.

There are certainly some SCAMs that are so nonsensical that they should not be researched, as is currently the case with homeopathy. I put it this way because I have researched homeopathy myself and, from my point of view, the situation was not so crystal clear 30 years ago.

Would you say that you have approached the matter with a sufficiently open mind?

No one can be completely unbiased. That’s why it’s important to do science properly, then you minimize bias as much as possible. When I took up my position at Exeter in 1993, I was perhaps somewhat biased towards homeopathy in a positive sense, because I had learned and used it myself, as well as other alternative medicine methods. The fact that the results then turned out to be negative in the vast majority of cases initially depressed me. But I have to live with that.

Every researcher prefers positive results, also because they are easier to publish. It was clear to me that, if I had succeeded in proving homeopathy right, I wouldn’t get one Nobel Prize, but two. Who wouldn’t want that?

(The interview was conducted by Hinnerk Feldwisch-Drentrup.)

he German press reported yesterday that the country’s Health Minister Karl Lauterbach plans  to remove homeopathic treatments from the benefits catalog of statutory health insurance companies. “Services that have no medically verifiable benefit should not be financed from contribution funds,” states a recommendation paper by the minister. “For this reason, we will remove the option for health insurance companies to include homeopathic and anthroposophic services in their statutes, thereby avoiding unnecessary expenditure by health insurance companies.” However, private supplementary insurance should still be possible.

Lauterbach had already announced last year that he would review the funding of homeopathic treatments. “Although homeopathy is not significant in terms of expenditure, it has no place in a science-based healthcare policy,” the SPD politician told “Der Spiegel” last October. The measure would save merely a maximum of ten million Euros. This is because firstly not all health insurance companies offer the option to reimburse homeopathy, and secondly, because not that many Germans use homeopathy.


Before I was joined about a decade ago by a group of excellent and effective skeptics, I seemed to be a lone, lost voice in Germany cautioning against the misunderstanding that homeopathy and anthroposophical medicine were backed by evidence. Thus, you probably think that I am rejoicing at this spectacular success. At first glance, it does indeed seem to be great news for those who support evidence-based medicine. But sadly, I also have second thoughts.

We should, I think, be concerned that Lauterbach intends to leave homeopathic and anthroposophical remedies reimbursible via private supplementary insurance. Most Germans have such insurance which means that, despite Lauterbach’s grand announcement, very little will probably change. Homeopathy and anthroposophic medicine, both pure placebo therapies, will still be able to pretend to be real medicine.

Moreover, we should be concerned about Lauterbach’s reasoning. It is, of course, laudable to point out that homeopathic and anthroposophic remedies are not demonstrably effective. But clearly, this is only half of the truth. The full truth is that they are based on totally ridiculous assumptions, that, in other words, they fly in the face of science. Only if we manage to get this message across, will we inform the public responsibly, in my view.

A total ban then? No, personally, I don’t want to ban homeopathic or anthroposophical remedies. If someone loves esoteric nonsense or placebos, he/she should, in my view, be able to buy them. But he/she should use their own money for the purchase. We should remember that wasting notoriously scarce public funds from either statutory or private health insurances is not just uneconomical but foremost unethical.



This systematic review aimed to investigate the effectiveness of cupping therapy on low back pain (LBP). Medline, Embase, Scopus and WANFANG databases were searched for relevant cupping RCTs on low back pain articles up to 2023. A complementary search was manually made on 27 September for update screening. Full-text English and Chinese articles on all ethnic adults with LBP of cupping management were included. Studies looking at acute low back pain only were excluded. Two independent reviewers screened and extracted data, with any disagreement resolved through consensus by a third reviewer. The methodological quality of the included studies was evaluated independently by two reviewers using an adapted tool. Change-from-baseline outcomes were treated as continuous variables and calculated according to the Cochrane Handbook. Data were extracted and pooled into the meta-analysis by Review Manager software (version 5.4, Nordic Cochrane Centre).

Eleven trials involving 921 participants were included. Five studies were assessed as being at low risk of bias, and six studies were of acceptable quality. The findings reveal:

  • High-quality evidence demonstrated cupping significantly improves pain at 2-8 weeks endpoint intervention (d=1.09, 95% CI: [0.35-1.83], p=0.004).
  • There was no continuous pain improvement observed at one month (d=0.11, 95% CI: [-1.02-1.23], p=0.85) and 3-6 months (d=0.39, 95% CI: [-0.09-0.87], p=0.11).
  • Dry cupping did not improve pain (d=1.06, 95% CI: [-0.34, 2.45], p=0.14) compared with wet cupping (d=1.5, 95% CI: [0.39-2.6], p=0.008) at the endpoint intervention.
  • There was no evidence indicating the association between pain reduction and different types of cupping (p=0.2).
  • Moderate- to low-quality evidence showed that cupping did not reduce chronic low back pain (d=0.74, 95% CI: [-0.67-2.15], p=0.30) and non-specific chronic low back pain (d=0.27, 95% CI: [-1.69-2.24], p=0.78) at the endpoint intervention.
  • Cupping on acupoints showed a significant improvement in pain (d=1.29, 95% CI: [0.63-1.94], p<0.01) compared with the lower back area (d=0.35, 95% CI: [-0.29-0.99], p=0.29).
  • A potential association between pain reduction and different cupping locations (p=0.05) was found.
  • Meta-analysis showed a significant effect on pain improvement compared to medication therapy (n=8; d=1.8 [95% CI: 1.22 – 2.39], p<0.001) and usual care (n=5; d=1.07 [95% CI: 0.21- 1.93], p=0.01).
  • Two studies demonstrated that cupping significantly mediated sensory and emotional pain immediately, after 24 hours, and 2 weeks post-intervention (d= 5.49, 95% CI [4.13-6.84], p<0.001).
  • Moderate evidence suggested that cupping improved disability at the 1-6 months follow-up (d=0.67, 95% CI: [0.06-1.28], p=0.03).
  • There was no immediate effect observed at the 2-8 weeks endpoint (d=0.40, 95% CI: [-0.51-1.30], p=0.39).
  • A high degree of heterogeneity was noted in the subgroup analysis (I2 >50%).

The authors concluded that high- to moderate-quality evidence indicates that cupping significantly improves pain and disability. The effectiveness of cupping for LBP varies based on treatment durations, cupping types, treatment locations, and LBP classifications. Cupping demonstrated a superior and sustained effect on pain reduction compared with medication and usual care. The notable heterogeneity among studies raises concerns about the certainty of these findings. Further research should be designed with a standardized cupping manipulation that specifies treatment sessions, frequency, cupping types, and treatment locations. The real therapeutic effects of cupping could be confirmed using a sham device or objective outcome measurements. Studies with at least six- to twelve-month follow-ups are needed to investigate the long-term efficacy of cupping in managing LBP.


No need, it’s really quite simple: cupping can, according to this review, be shown to have some short-lasting effect, provided the study is flawed and does not control for placebo effects.


No need! There is hardly a form of so-called alternative medicine (SCAM) that does not have a similarly small effect of back pain, if tested in equally dodgy studies. This is particularly true for those treatments that can act as a theatrical placebo, e.g. acupuncture or chiropractic.

So, should a back pain sufferer try cupping?

If he/she insists, why not? But please don’t use wet cupping (which can do quite a bit of harm). Dry cupping (without injuring the skin) is arguably better (less risk, less expense, possibility of home treatment by your partner) than chiropractic, osteopathy, acupuncture, or many other SCAMs.

My conclusions – as mentioned many times previously – are as follows:

  1. Most SCAMs help a little with back pain (and similar conditions) because they can have a powerful placebo effect.
  2. Conventional medicine is also not convincingly effective for back pain.
  3. If you insist on SCAM, it is best to use one that is relatively harmless and inexpensive.

Diabetic peripheral neuropathy (DPN) is a common complication of diabetes mellitus and can lead to serious complications. Therapeutic strategies for pain control are available but there are few approaches that influence neurological deficits such as numbness.

This study investigated the effectiveness of acupuncture on improving neurological deficits in patients suffering from type 2 DPN.

The acupuncture in DPN (ACUDPN) study was a two-armed, randomized, controlled, parallel group, open, multicenter clinical trial. Patients were randomized in a 1:1 ratio into two groups: The acupuncture group received 12 acupuncture treatments over 8 wk, and the control group was on a waiting list during the first 16 wk, before it received the same treatment as the other group. Both groups received routine care.

Outcome parameters were evaluated after 8, 16 and 24 wk. They included:

  • neurological scores, such as an 11-point numeric rating scale (NRS) for hypesthesia,
  • neuropathic pain symptom inventory (NPSI),
  • neuropathy deficit score (NDS),
  • neuropathy symptom score (NSS);
  • nerve conduction studies (NCS) as assessed with a handheld point-of-care device.

Sixty-two participants were included. The NRS for numbness showed a difference of 2.3 (P < 0.001) in favor of the acupuncture group, the effect persisted until week 16 with a difference of 2.2 (P < 0.001) between groups and 1.8 points at week 24 compared to baseline. The NPSI was improved in the acupuncture group by 12.6 points (P < 0.001) at week 8, the NSS score at week 8 with a difference of 1.3 (P < 0.001); the NDS and the TNSc score improved for the acupuncture group in week 8, with a difference of 2.0 points (P < 0.001) compared to the control group. Effects were persistent in week 16 with a difference of 1.8 points (P < 0.05). The NCS showed no meaningful changes. In both groups only minor side effects were reported.

The authors concluded that acupuncture may be beneficial in type 2 diabetic DPN and seems to lead to a reduction in neurological deficits. No serious adverse events were recorded and the adherence to treatment was high. Confirmatory randomized sham-controlled clinical studies with adequate patient numbers are needed to confirm the results.

That “acupuncture may be beneficial” has been known before and presumably was the starting point of the present study. So, why conduct an open, under-powered trial with non-blind assessors and without defining a primary outcome measure?

Could the motivation be to add yet another false-positive study to the literature of acupuncture?

False-positive, you ask?

Yes, let me explain by having a look at the outcome measures:

  • NRS = a subjective endpoint.
  • NPSI = a subjective endpoint.
  • NDS = a subjective endpoint.
  • NSS = a subjective endpoint.
  • NCS = the only objective endpoint.

And what is remarkable about that?

  • Subjective endpoints are likely to respond to placebo effects.
  • Objective endpoints are not likely to respond to placebo effects.

In other words, what the authors of this study have, in fact, confirmed with their study is this:

acupuncture is a theatrical placebo!

Some articles are just too remarkable for me to alter them in any way. This one impresses already by its title: “Ameliorative effects of homeopathic medicines in the management of different cancers“. By way of a ‘Christmas treat’, here its summary:

Homeopathy is a commonly used complementary and alternative system of medicine for the treatment of various sorts of ailments throughout the world. Homeopathic medicines are made up of potential therapeutic natural products that are primarily acknowledged for their low doses as well as extended patient survival results. Homeopathic medicines are derived from plants such as arnica (mountain herb), red onion, poison ivy, stinging nettle, and belladonna (deadly nightshade); minerals including white arsenic as well as from animals such as crushed whole bees. Homeopathic medicines are synthesized as sugar pellets to be placed under the tongue and may also be used in the form of gels, ointments, drops, tablets, and creams. Homeopathic medicines can be used to treat various disorders including migraine, depression, gastrointestinal diseases, joint pain, inflammation, different sorts of injuries, flu, arthritis as well as sciatica.

Cancer is the 2nd major reason behind global mortalities. It is revealed that developing countries around the world shoulder most of the cancer burden. According to a survey conducted in 2020, low- and middle-income countries face 70% of the total mortalities worldwide which accounts for approximately 10 million people of these countries. Homeopathic medicines ensure low-cost cancer treatment with little or no side effects on the bodies of humans and animals. Besides, it is applied as a supportive and palliative therapy in a broad range of cancer patients to enhance the body’s fight against cancer, alleviate discomfort resulting from disease or conventional treatments as well as improve the general well-being of the patients. In this chapter, our primary focus will be on the anti-cancerous effects of homeopathic medicines against different cancerous conditions in the body along with their mechanism of action.

Let me just mention a few fairly obvious points:

My conclusion:

Those who advocate homeopathy don’t know what it is, while those who know what it is, don’t advocate it.

I was alerted to a new book entitled “Handbook of Space Pharmaceuticals“. It contains a chapter on “Homeopathy as a Therapeutic Option in Space” (yes, I am not kidding!). Here is its abstract (the numbers were inserted by me and refer to the short comments below):

Homeopathy is one of the largest used unorthodox medicinal systems having a wide number of principles and logic to treat and cure various diseases [1]. Many successful concepts like severe dilution to high agitation have been applied in the homeopathic system [2]. Though many concepts like different treatment for same diseases and many more are contradictory to the allopathic system [3], homeopathy has proved its worth in decreasing drug-related side effects in many arenas [4]. Various treatments and researches are carried out on various diseases; mostly homeopathic treatment is used in joint diseases, respiratory diseases, cancer, and gastrointestinal tract diseases [5]. In this chapter, readers will have a brief idea about many meta-analysis results of most common respiratory diseases, i.e., asthma, incurable hypertension condition, rheumatoid arthritis, and diarrhea and a megareview of all the diseases to see their unwanted effects, uses of drugs, concepts, and issues related to homeopathy [6]. Various limitations of homeopathic treatments are also highlighted which can give a clear idea about the future scope of research [7]. Overall, it can be concluded that placebo and homeopathic treatments give almost the same effect [8], but the less severe side effects of homeopathic drugs in comparison to all other treatment groups catch great attention [9].

Apart from the very poor English of the text and the fact that it has as good as nothing to do with the subject of ‘Homeopathy as a Therapeutic Option in Space’, I have the following brief comments:

  1. I did not know that homeopathy has ‘a wide number of logic’ and had alwas assumed that there is only one logic.
  2. Successful concepts? Really?
  3. So, homeopaths believe that the ‘allopathic system’ treats the same diseases uniformly? In this case, they should perhaps read up what conventional medicine really does.
  4. I am not aware of good evidence showing that homeopathy reduces drug related adverse effects.
  5. No, homeopathy is used for all symptoms – Hahnemann did not believe in treating disease entities – and mostly for those that are self-limiting.
  6. I love the term ‘incurable hypertension condition’; can somebody please explain what it is?
  7. The main limitation is that homeopathy is nonsense and, as such, does not really require further research.
  8. Not ‘almost’ but ‘exactly’! But thanks for pointing it out.
  9. Wishful thinking and not true. Firstly, the author forgot about ‘homeopathic aggravations’ in which homeopaths so strongly believe. Secondly, I know of many non-homeopathic treatments that are free of adverse effects when done properly.

Altogether, I am as disappointed by this article as you must be: we were probably all hoping to hear about the discovery showing that homeopathy works splendidly in space – not least because we have known for a while that homeopaths seem to be from a different planet.
