This study investigated the potential benefits of auricular point acupressure on cerebrovascular function and stroke prevention among adults with a high risk of stroke.
A randomized controlled study was performed with 105 adults at high risk for stroke between March and July 2021. Participants were randomly allocated to receive either
- auricular point acupressure with basic lifestyle interventions (n = 53) or
- basic lifestyle interventions alone (n = 52) for 2 weeks.
The primary outcome was the kinematic and dynamic indices of cerebrovascular function, as well as the CVHP score at week 2, measured by the Doppler ultrasonography and pressure transducer on carotids.
Of the 105 patients, 86 finished the study. At week 2, the auricular point acupressure therapy with lifestyle intervention group had higher kinematic indices, cerebrovascular hemodynamic parameters score, and lower dynamic indices than the lifestyle intervention group.
The authors concluded that ccerebrovascular function and cerebrovascular hemodynamic parameters score were greater improved among the participants undergoing auricular point acupressure combined with lifestyle interventions than lifestyle interventions alone. Hence, the auricular point acupressure can assist the stroke prevention.
Acupuncture is a doubtful therapy.
Acupressure is even more questionable.
Ear acupressure is outright implausible.
The authors discuss that the physiological mechanism underlying the effect of APA therapy on cerebrovascular hemodynamic function is not fully understood at present. There may be two possible explanations.
- First, a previous study has demonstrated that auricular acupuncture can directly increase mean blood flow velocity in the middle cerebral artery.
- Second, cerebrovascular hemodynamic function is indirectly influenced by the effect of APA therapy on blood pressure.
I think there is a much simpler explanation: the observed effects are directly or indirectly due to placebo. As regular listeners of this blog know only too well by now, the A+B versus B study design cannot account for placebo effects. Sadly, the authors of this study hardly discuss this explanation – that’s why they had to publish their findings in just about the worst SCAM journal of them all: EBCAM.
Semen retention is a so-called alternative medicine (SCAM) that involves intentionally avoiding ejaculating. A person can do this by abstaining from any sexual activity, stopping before the point of ejaculation, or teaching themselves to orgasm without ejaculating.
Although this practice may seem new, this is likely only due to recent internet popularity. In fact, semen retention is an ancient practice, believed to boost male physical and spiritual energy.
Some other names for semen retention include:
- coitus reservatus
- seminal conservation
- sexual continence
It is also known as or included in practices called:
- karezza (Italian)
- maithuna (Hindu Tantra)
- sahaja (Hindu Yoga)
- tantra (Hinduism and Buddhism)
- cai Yin pu Yang and cai Yang pu Yin (Taoist)
Semen retention is said to be good for a range of things:
- increased motivation
- improved energy and focus
- more self-confidence
- reduced anxiety
- better memory
- improved concentration
- clearer skin
- increased testosterone
- more weight loss
- increased muscle mass
- physical rejuvenation
- a deeper voice
- a greater sense of purpose
- stronger or deeper emotional bonds in relationships
- a stronger sense of overall harmony
Yes, I agree, this sounds weird!
But is there any evidence?
Males of some species use mate retention behavior and investment in ejaculate quality as anti-cuckoldry tactics concurrently while others do so in a compensatory fashion. Leivers, Rhodes, and Simmons (2014) reported that men who performed mate retention less frequently produced higher-quality ejaculates, suggesting that humans use these tactics compensatorily. We conducted a conceptual replication of this research in a sample of 41 men (18-33 years; M = 23.33; SD = 3.60). By self-report, participants had not had a vasectomy and had never sought infertility treatment. We controlled for several covariates known to affect ejaculate quality (e.g., abstinence duration before providing an ejaculate) and found no statistically significant relationships between mate retention behavior and four components of ejaculate quality: sperm velocity, sperm concentration, slow motility, and ejaculate volume. The present results provide little support for the hypothesis that human males deploy mate retention behavior and ejaculate quality investment compensatorily. We discuss the limitations of this study and highlight the need for research to address questions about the nature of anti-cuckoldry tactic deployment in humans, especially concerning investment in ejaculate quality.
In species where females mate with multiple males, the sperm from these males must compete to fertilise available ova. Sexual selection from sperm competition is expected to favor opposing adaptations in males that function either in the avoidance of sperm competition (by guarding females from rival males) or in the engagement in sperm competition (by increased expenditure on the ejaculate). The extent to which males may adjust the relative use of these opposing tactics has been relatively neglected. Where males can successfully avoid sperm competition from rivals, one might expect a decrease in their expenditure on tactics for the engagement in sperm competition and vice versa. In this study, we examine the relationship between mate guarding and ejaculate quality using humans as an empirical model. We found that men who performed fewer mate guarding behaviors produced higher quality ejaculates, having a greater concentration of sperm, a higher percentage of motile sperm and sperm that swam faster and less erratically. These effects were found independent of lifestyle factors or factors related to male quality. Our findings suggest that male expenditure on mate guarding and on the ejaculate may represent alternative routes to paternity assurance in humans.
The uncritical application of western psychiatric concepts in non-western societies resulting in culturally invalid psychiatric syndromes, have been extensively documented. Such instances are considered ‘category errors’. In contrast, ‘reverse category errors’ although theoretically postulated, have never been empirically demonstrated. Diagnostic criteria of an established South Asian culture specific neurosis, Dhāt syndrome, were deployed by a psychiatrist of South Asian origin, amongst 47 white Britons in London, UK, presenting for the first time with a clinic diagnosis of ICD-9 Depressive Neurosis (Dysthymic Disroder, ICD-11). The proceedure yielded a new disorder, Semen Retention Syndrome. Based on narrative accounts and quantitative scores on the Hamilton Depression Rating Scale, the evidence suggests that a significant subset of white British subjects diagnosed with Dysthymic Disorder, may in fact be expressing a psychological variation of a previously unknown local White British somatisation phenomena labelled Semen Retention Syndrome. Anxiety and depressive symptoms presented by this subset of subjects were primarily attributed to a core irrational belief and a cognitive error centered around misunderstood concepts of semen physiology. Consequently, the undue focus on mood idioms by both white British patients and their health professionals, leads to a mistaken diagnosis of Mood Disorder, and results in incorrect treatment. The implications of this ethnocentric mode of reasoning raises concerns about existing concepts in psychiatric phenomenology and for official international diagnostic classificatory systems. The paper concludes by arguing that category errors in both directions are instances of cultural iatrogenesis, and underscore the importance of a culturally valid psychiatry.
I was unable to find support for any of the above-listed effects of semen retention. So, claims like “Semen Retention is life-changing, especially for men. Not only, it help you turn into a real alpha male but also offers great health benefits” need to be taken with a pinch of salt. Yet, it did occur to me that semen retention might have one positive outcome:
It reduces the chances of stupid people multiplying!
An explanatory sequential mixed methods study with three separate phases was conducted in Danish patients with lumbar radiculopathy receiving a standardized chiropractic care package (SCCP). Lumbar radiculopathy is pain and other neurological symptoms caused by the pinching of nerve roots where they leave your spinal cord in the lumbar region.
Phase one of the study was a quantitative analysis based on a survey in a prospective cohort of patients with lumbar radiculopathy in an SCCP from 2018 to 2020. Patients rated their satisfaction with the examination, information, treatment effect, and overall management of their problem on a 0–10 scale. In phase two, six semi-structured interviews conducted in 2021 were used to gain further explanatory insights into the findings from phase one. Data were analyzed using systematic text condensation. In phase three, the quantitative and qualitative data were merged in a narrative joint display to obtain a deeper understanding of the overall results.
Here I am only interested in the patients’ perception of the treatment effect. Of 303 eligible patients, 238 responded to the survey. Of these, 50% were very satisfied with the treatment effect.
The authors stated that patients in their study expected a rapid and persistent decrease in symptoms, which, unfortunately, does not match the prognosis of lumbar radiculopathy. Although the prognosis is considered good, the improvement happens gradually and often with fluctuating pain patterns, and it is not unusual to have milder symptoms for three months or longer.
So, only half of the patients who had chosen to consult chiropractors for their lumbar radiculopathy were very satisfied with the treatment results. In most patients, the symptoms decreased only gradually often with fluctuating pain patterns, and the authors comment that symptoms frequently last for three months or longer with a SCCP.
Might I point out that what is being described here looks to me very much like the natural history of lumbar radiculopathy? About 90% of patients with back pain caused by disc herniation see improvements within three months without therapy. Are the authors aware that their observational study is in accordance with the notion that the SCCP does nothing or very little to help patients suffering from lumbar radiculopathy?
It has been reported, at the German Medical Congress (DÄT) a year ago, that it was decided to delete the additional title of homeopathy from the model further training regulations of the German Medical Association. And Federal Health Minister Karl Lauterbach (SPD) tweeted applause: “Homeopathy has no place in modern medicine.”
Now the ‘ Bundesverband der Pharmaziestudierenden in Deutschland’ (BPhD), the German Pharmacists Organization, even goes a few steps further. The position paper distinguishes between evidence-based medicine (EBM) and unproven therapeutic methods. According to the BPhD, these include homeopathy, but also anthroposophy, traditional Chinese medicine, and traditional medicines.
Among other things, the BPhD is disturbed by the way homeopathy presents itself as an alternative, because an alternative means “a choice between two equally suitable possibilities” to achieve a goal, and this is not the case. Compared to evidence-based medicine (EBM), homeopathy is a “constructed, illusory concept” and “the principles of homeopathic teachings and principles” are to be rejected as “unscientific”. According to the BPhD, a designation as “alternative” for advertising purposes should no longer be allowed.
They would also like to see a demarcation from naturopathy; the clear distinction between homeopathy and phytopharmacy has been lacking up to now. The advertising attribute “natural” should therefore also be banned in order to prevent equalization in advertising, the position paper states.
Like doctors, pharmacy students point to the lack of proof of efficacy beyond the placebo effect. According to the BPhD, the dogma WER HEILT HAT RECHT, “he who heals is right” would “disregard all processes that work towards healing and glorify the result”. The “gold standard” of EBM – randomized, double-blind studies with placebo control – should in future also have to be fulfilled by homeopathic medicines, experience reports are not sufficient, it continues.
Homeopathic medicines are only registered as medicinal products without indication, which requires neither proof of efficacy nor clinical studies. The BPhD, therefore, demands that a warning be placed on the preparations that they have “no proven efficacy beyond the placebo effect”. Up to now, without this warning, patients have been “deceived about the efficacy”, and there is an “urgent need for detailed public information and counseling on homeopathy since its unjustified reputation poses a danger of not seeking treatment”. The BPhD also demands that the status of homeopathic medicines is withdrawn and that the pharmacy obligation for the preparations is abolished…
“In the health professions, no trivialization of unproven therapeutic procedures should be tolerated, as inadequate counseling or ignorance poses a danger to patients,” the BPhD said.
When I first read this article – I translated and shortened it for those who cannot read German- I was truly dazzled. These are the suggestions that I have been making for around 20 years now, not specifically for Germany but for pharmacists in general. For many years, the Germans seemed the least likely to agree with me. But now they seem to be ahead of everyone else in Europe!
I suspect and hope that our recent initiative might have something to do with it.
Let’s hope that the pharmacists of other countries follow the German example.
On this blog, we have some people who continue to promote conspiracy theories about Covid and Covid vaccinations. It is, therefore, time, I feel, to present them with some solid evidence on the subject (even though it means departing from our usual focus on SCAM).
This Cochrane review assessed the efficacy and safety of COVID‐19 vaccines (as a full primary vaccination series or a booster dose) against SARS‐CoV‐2. An impressive team of investigators searched the Cochrane COVID‐19 Study Register and the COVID‐19 L·OVE platform (last search date 5 November 2021). They also searched the WHO International Clinical Trials Registry Platform, regulatory agency websites, and Retraction Watch. They included randomized controlled trials (RCTs) comparing COVID‐19 vaccines to placebo, no vaccine, other active vaccines, or other vaccine schedules.
A total of 41 RCTs could be included and analyzed assessing 12 different vaccines, including homologous and heterologous vaccine schedules and the effect of booster doses. Thirty‐two RCTs were multicentre and five were multinational. The sample sizes of RCTs were 60 to 44,325 participants. Participants were aged: 18 years or older in 36 RCTs; 12 years or older in one RCT; 12 to 17 years in two RCTs; and three to 17 years in two RCTs. Twenty‐nine RCTs provided results for individuals aged over 60 years, and three RCTs included immunocompromised patients. No trials included pregnant women. Sixteen RCTs had two‐month follow-ups or less, 20 RCTs had two to six months, and five RCTs had greater than six to 12 months or less. Eighteen reports were based on preplanned interim analyses. The overall risk of bias was low for all outcomes in eight RCTs, while 33 had concerns for at least one outcome. 343 registered RCTs with results not yet available were identified.The evidence for mortality was generally sparse and of low or very low certainty for all WHO‐approved vaccines, except AD26.COV2.S (Janssen), which probably reduces the risk of all‐cause mortality (risk ratio (RR) 0.25, 95% CI 0.09 to 0.67; 1 RCT, 43,783 participants; high‐certainty evidence).High‐certainty evidence was found that BNT162b2 (BioNtech/Fosun Pharma/Pfizer), mRNA‐1273 (ModernaTx), ChAdOx1 (Oxford/AstraZeneca), Ad26.COV2.S, BBIBP‐CorV (Sinopharm‐Beijing), and BBV152 (Bharat Biotect) reduce the incidence of symptomatic COVID‐19 compared to placebo (vaccine efficacy (VE): BNT162b2: 97.84%, 95% CI 44.25% to 99.92%; 2 RCTs, 44,077 participants; mRNA‐1273: 93.20%, 95% CI 91.06% to 94.83%; 2 RCTs, 31,632 participants; ChAdOx1: 70.23%, 95% CI 62.10% to 76.62%; 2 RCTs, 43,390 participants; Ad26.COV2.S: 66.90%, 95% CI 59.10% to 73.40%; 1 RCT, 39,058 participants; BBIBP‐CorV: 78.10%, 95% CI 64.80% to 86.30%; 1 RCT, 25,463 participants; BBV152: 77.80%, 95% CI 65.20% to 86.40%; 1 RCT, 16,973 participants).Moderate‐certainty evidence was found that NVX‐CoV2373 (Novavax) probably reduces the incidence of symptomatic COVID‐19 compared to placebo (VE 82.91%, 95% CI 50.49% to 94.10%; 3 RCTs, 42,175 participants).There is low‐certainty evidence for CoronaVac (Sinovac) for this outcome (VE 69.81%, 95% CI 12.27% to 89.61%; 2 RCTs, 19,852 participants).High‐certainty evidence was found that BNT162b2, mRNA‐1273, Ad26.COV2.S, and BBV152 result in a large reduction in the incidence of severe or critical disease due to COVID‐19 compared to placebo (VE: BNT162b2: 95.70%, 95% CI 73.90% to 99.90%; 1 RCT, 46,077 participants; mRNA‐1273: 98.20%, 95% CI 92.80% to 99.60%; 1 RCT, 28,451 participants; AD26.COV2.S: 76.30%, 95% CI 57.90% to 87.50%; 1 RCT, 39,058 participants; BBV152: 93.40%, 95% CI 57.10% to 99.80%; 1 RCT, 16,976 participants).
Moderate‐certainty evidence was found that NVX‐CoV2373 probably reduces the incidence of severe or critical COVID‐19 (VE 100.00%, 95% CI 86.99% to 100.00%; 1 RCT, 25,452 participants).
Two trials reported high efficacy of CoronaVac for severe or critical disease with wide CIs, but these results could not be pooled.
mRNA‐1273, ChAdOx1 (Oxford‐AstraZeneca)/SII‐ChAdOx1 (Serum Institute of India), Ad26.COV2.S, and BBV152 probably result in little or no difference in serious adverse events (SAEs) compared to placebo (RR: mRNA‐1273: 0.92, 95% CI 0.78 to 1.08; 2 RCTs, 34,072 participants; ChAdOx1/SII‐ChAdOx1: 0.88, 95% CI 0.72 to 1.07; 7 RCTs, 58,182 participants; Ad26.COV2.S: 0.92, 95% CI 0.69 to 1.22; 1 RCT, 43,783 participants); BBV152: 0.65, 95% CI 0.43 to 0.97; 1 RCT, 25,928 participants). In each of these, the likely absolute difference in effects was fewer than 5/1000 participants.
Evidence for SAEs is uncertain for BNT162b2, CoronaVac, BBIBP‐CorV, and NVX‐CoV2373 compared to placebo (RR: BNT162b2: 1.30, 95% CI 0.55 to 3.07; 2 RCTs, 46,107 participants; CoronaVac: 0.97, 95% CI 0.62 to 1.51; 4 RCTs, 23,139 participants; BBIBP‐CorV: 0.76, 95% CI 0.54 to 1.06; 1 RCT, 26,924 participants; NVX‐CoV2373: 0.92, 95% CI 0.74 to 1.14; 4 RCTs, 38,802 participants).
The authors’ conclusions were as follows: Compared to placebo, most vaccines reduce, or likely reduce, the proportion of participants with confirmed symptomatic COVID‐19, and for some, there is high‐certainty evidence that they reduce severe or critical disease. There is probably little or no difference between most vaccines and placebo for serious adverse events. Over 300 registered RCTs are evaluating the efficacy of COVID‐19 vaccines, and this review is updated regularly on the COVID‐NMA platform (covid-nma.com).

And as some might say this analysis is not new, here are two further papers just out:
Objectives To determine the association between covid-19 vaccination types and doses with adverse outcomes of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection during the periods of delta (B.1.617.2) and omicron (B.1.1.529) variant predominance.
Design Retrospective cohort.
Setting US Veterans Affairs healthcare system.
Participants Adults (≥18 years) who are affiliated to Veterans Affairs with a first documented SARS-CoV-2 infection during the periods of delta (1 July-30 November 2021) or omicron (1 January-30 June 2022) variant predominance. The combined cohorts had a mean age of 59.4 (standard deviation 16.3) and 87% were male.
Interventions Covid-19 vaccination with mRNA vaccines (BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna)) and adenovirus vector vaccine (Ad26.COV2.S (Janssen/Johnson & Johnson)).
Main outcome measures Stay in hospital, intensive care unit admission, use of ventilation, and mortality measured 30 days after a positive test result for SARS-CoV-2.
Results In the delta period, 95 336 patients had infections with 47.6% having at least one vaccine dose, compared with 184 653 patients in the omicron period, with 72.6% vaccinated. After adjustment for patient demographic and clinical characteristics, in the delta period, two doses of the mRNA vaccines were associated with lower odds of hospital admission (adjusted odds ratio 0.41 (95% confidence interval 0.39 to 0.43)), intensive care unit admission (0.33 (0.31 to 0.36)), ventilation (0.27 (0.24 to 0.30)), and death (0.21 (0.19 to 0.23)), compared with no vaccination. In the omicron period, receipt of two mRNA doses were associated with lower odds of hospital admission (0.60 (0.57 to 0.63)), intensive care unit admission (0.57 (0.53 to 0.62)), ventilation (0.59 (0.51 to 0.67)), and death (0.43 (0.39 to 0.48)). Additionally, a third mRNA dose was associated with lower odds of all outcomes compared with two doses: hospital admission (0.65 (0.63 to 0.69)), intensive care unit admission (0.65 (0.59 to 0.70)), ventilation (0.70 (0.61 to 0.80)), and death (0.51 (0.46 to 0.57)). The Ad26.COV2.S vaccination was associated with better outcomes relative to no vaccination, but higher odds of hospital stay and intensive care unit admission than with two mRNA doses. BNT162b2 was generally associated with worse outcomes than mRNA-1273 (adjusted odds ratios between 0.97 and 1.42).
Conclusions In veterans with recent healthcare use and high occurrence of multimorbidity, vaccination was robustly associated with lower odds of 30 day morbidity and mortality compared with no vaccination among patients infected with covid-19. The vaccination type and number of doses had a significant association with outcomes.
SECOND EXAMPLE Long COVID, or complications arising from COVID-19 weeks after infection, has become a central concern for public health experts. The United States National Institutes of Health founded the RECOVER initiative to better understand long COVID. We used electronic health records available through the National COVID Cohort Collaborative to characterize the association between SARS-CoV-2 vaccination and long COVID diagnosis. Among patients with a COVID-19 infection between August 1, 2021 and January 31, 2022, we defined two cohorts using distinct definitions of long COVID—a clinical diagnosis (n = 47,404) or a previously described computational phenotype (n = 198,514)—to compare unvaccinated individuals to those with a complete vaccine series prior to infection. Evidence of long COVID was monitored through June or July of 2022, depending on patients’ data availability. We found that vaccination was consistently associated with lower odds and rates of long COVID clinical diagnosis and high-confidence computationally derived diagnosis after adjusting for sex, demographics, and medical history.
There are, of course, many more articles on the subject for anyone keen to see the evidence. Sadly, I have little hope that the COVID loons will be convinced by any of them. Yet, I thought I should give it nevertheless a try.
In response to yesterday’s post, I received a lengthy comment from ‘Stan’. Several readers have already commented on it. Therefore, I can make my arguments short. In this post, will repeat Stan’s points each followed by my comments (in bold). Here we go:
Seven Reasons Homœopathy is Not Placebo Effect
Sorry, Stan, but your heading is not proper English; I have therefore changed it for the title of this post.
1. Homeopathic remedies work on babies, animals, plants and people in a coma. Biodynamic farmers use homeopathic remedies to repel pests and treat plant diseases. Some organic ranchers rely on homeopathic remedies to treat their herds. Some “placebo by proxy” effect has been shown for children but its doubtful that it could be shown for a herd of cattle or crops in a field. Farmers can’t rely on wishful thinking to stay in business.
As discussed ad nauseam on this blog, homeopathic remedies do not work on babies or animals better than placebos. I don’t know of any studies with “people in a coma” (if you do, Stan, please let me know). The fact that ranchers rely on homeopathy is hilarious but does not prove anything.
2. The correct curative remedy will initially cause a worsening of the condition being cured if it is given in too strong (i.e. too dilute) a dose. A placebo might only cause a temporary improvement of the condition being treated; certainly not an aggravation.
The ‘homeopathic aggravation’ is a myth created by homeopaths. It disappears if we try to systematically research it; see here, for instance.
3. One can do a “proving” of an unknown homeopathic remedy by taking it repeatedly over several days and it will temporarily cause symptoms that one has never experienced previously – symptoms it will cure in a sick person. This is a repeatable scientific experiment used to determine the scope of a new remedy, or confirm the effects of an already proven remedy. A placebo might possibly have an effect if the individual taking it has been “prepared” by being told what they are taking but it likely wouldnt match previously recorded symptoms in the literature.
Homeopathic provings are rubbish and not reproducible when done rigorously; see here.
4. One can treat simple acute (self-limiting) conditions (e.g. minor burns, minor injuries, insect bites, etc.) and see unusually rapid cures with homeopathic remedies. A placebo might only cause a temporary improvement of the condition being treated while taken. Placebos have been found mostly effective in conditions with a strong psychological component like pain.
You mean like using Arnica for cuts and bruises? Sadly, it does not work.
5. One can get homeopathic treatment for long term chronic (non self-limiting) conditions and see a deep lasting cure, as has been documented clinically for a couple centuries. A placebo might only cause a temporary partial improvement of the condition being treated while the placebo is being taken.
You mean like asthma, eczema, or insomnia?
6. There is over 200 years worth of extensive documentation from around the world, of the clinical successes of homeopathy for both acute and chronic conditions of all types. As Dr Hahn has said you have throw out 90% of the evidence to conclude that homeopathy doesnt work. The Sheng et al meta-analysis in 2005 Lancet that was supposedly the death knell of homeopathy used only 8 studies, excluding hundreds of others. Unsurprisingly homeopathy was found wanting. So-called Skeptics see what they want to see in the science. There is relatively little documentation of placebo usage. A few recent studies have been done showing the limited temporary benefits of placebos.
What Hahn wrote is understandably liked by homeopaths but it nevertheless is BS. If you don’t trust me, please rely on independent bodies from across the world.
7. Homeopathic remedies have been shown to have a very weak electromagnetic signature and contain some nano-particles. Some believe this explains their mechanism. An exciting new potential field of research is the subtle cell signalling that has been found to direct the development of stem cells. Scientists have created double-headed planeria worms and this trait has been found to be inherited by their offspring without any change in the genes or epigenetics. Until now we had no idea how a single fertilized ovum could evolve into a complex creature that is bilateral and has multiple cell types. It is possible that the very subtle electromagnetic signature or some other unknown effect of homeopathic remedies is effecting this subtle cell signalling.
The homeopathic nano-myth is nonsense. And so is the rest of your assumptions.
Every conventional drug has “side effects” that match the symptoms for which it is indicated! Aspirin can cause headaches and fever, ritalin can cause hyperactive effects, radiation can cause cancer. Conventional doctors are just practicing bad homeopathy. They are prescribing Partially similar medicines. If their drugs were homeopathic (i.e. similar) to the patients symptoms on all levels they would be curative. Radiation sometimes does cure cancer instead of just suppressing it per usual.
Even if this were true, what would it prove? Certainly not that homeopathy works!
Dr Hahneman did forbid mixing homeopathy and conventional medicine. In his day doctors commonly used extensive blood letting and extreme doses of mercury. Its not Quite as bad now.
You evidently did not read Hahnemann’s writings.
Just because we dont know how extremely dilute homeopathic remedies work, doesn’t discount that they Do work. Homeopathy seems to fly in the face of Known science. In no way is it irrational or unscientific. There are lots of phenomena in the universe that cant be explained yet, like dark energy and dark matter effects and even consciousness!
Not knowing how a treatment works has not stopped science to test whether it works (e.g. Aspirin). In the case of homeopathy, the results of these endeavors were not positive.
The assumption that the moon is made of cheese also flies in the face of science; do you perhaps think that this makes it true?
The actions of homeopathy can and have been well-explained: they are due to placebo effects.
Stan, thank you for this entertaining exercise. But, next time, please remember to supply evidence for your statements.
After all these years, I am still fascinated by what proponents of homeopathy try to tell others about their trade. Recently I found a long article in this vein. It is aimed at an audience of HEILPRAKTIKER and their patients. It should therefore be responsible, thorough, and evidence-based (yes, I am an optimist).
“With this article”, the authors state, “we aim to provide a comprehensive overview of homeopathy and help people make informed decisions about their health. Whether you already have experience with homeopathy or simply want to inform yourself, we hope that this article will provide you with valuable insights and information” (my translation).
Here I present to you just the relatively short section dedicated to the ‘pros and cons’ of homeopathy. Here we go:
Advantages of homeopathy:
- Holistic approach: homeopathy considers the human being as a whole and takes into account both physical and emotional aspects. It aims to support individual balance and the body’s self-healing powers.
- Gentle and non-invasive treatment: Homeopathic remedies are usually taken as globules, drops, or tablets and are therefore easy and convenient to use. They rarely cause side effects and are generally well tolerated.
- Individualized treatment: In homeopathy, each patient is considered unique and treatment is based on individual symptoms and characteristics. There is no “one-size-fits-all” solution, but a personalized approach.
- Support for chronic diseases: Homeopathy can be an alternative or complementary treatment for chronic conditions where conventional medicines offer limited relief. It can help improve quality of life and promote overall well-being.
Limitations of homeopathy:
- Placebo effect: Much of the effect of homeopathy is attributed to the placebo effect. It is argued that the improvements patients experience occur because of belief in the efficacy of the remedies and positive expectations, rather than due to a specific effect of the diluted substances.
- Lack of scientific evidence: The scientific evidence for the efficacy of homeopathy is limited and controversial. Many studies have failed to demonstrate benefits beyond the placebo effect. There is a lack of well-conducted randomized controlled trials that clearly show the effectiveness of homeopathy.
- Delay or rejection of conventional treatments: In some cases, the choice of homeopathy as the sole method of treatment may lead to delays in the diagnosis and timely treatment of serious or acute illnesses. It is important that serious illnesses are examined by a doctor and treated appropriately.
- Difficulties in standardization: Homeopathy involves a variety of remedies used in different potencies and dilutions. This makes standardization and the conduct of reproducible studies difficult. There are also controversial debates about whether the dilutions go beyond the extent to which molecules of the original substance are still present.
I am sure that you have heard the BS about the alleged advantages of homeopathy often enough. Therefore, I will here not bother to comment on them again. More interesting, in my view, are the limitations of homeopathy, as seen by its proponents. Please allow me, therefore, to discuss them briefly.
- The authors state that “it is argued that the improvements patients experience occur because of belief in the efficacy of the remedies and positive expectations”. This sounds as though this is a mere aberrant opinion or at least an ongoing debate amongst scientists. In fact, it is the scientific consensus supported by tons of evidence.
- This is the same point expressed differently.
- The admission that “the choice of homeopathy as the sole method of treatment may lead to delays in the diagnosis and timely treatment” is yet another way of stating that homeopathy is not effective. What is, however, not expressed clearly enough, in my view, is the fact that homeopathic treatment usually amounts to medical neglect which is unethical and can cause serious harm, in extreme cases even death.
- It is not true that the range of potencies renders “the conduct of reproducible studies difficult”. There are plenty of examples to demonstrate this, for instance, this study. “There are also controversial debates about whether the dilutions go beyond the extent to which molecules of the original substance are still present.” Yes, I did translate this correctly. I am sorry to say that this sentence does make no sense in German or in English.
What I find particularly interesting is that the authors do not mention disadvantages that non-homeopaths would rate as quite important, e.g.:
- The assumptions of homeopathy fly in the face of science.
- Hahnemann strictly forbade homeopathy to be combined with ‘allopathy’ (yet proponents now claim this option to be an advantage).
- Treating a patient with homeopathy violates even the most basic rules of medical ethics.
- Homeopaths have no choice but to lie to their patients on a daily basis.
- Many homeopaths have the nasty habit of advising their patients against using effective treatments, e.g. vaccinations.
- Homeopathy undermines rational thinking in a general way.
In summary, the authors’ “aim to provide a comprehensive overview of homeopathy and help people make informed decisions about their health” has not been reached.
The well-known Dr. Chris van Tulleken recently joined forces with Professor Michael Heinrich and Dr. Anthony Booker from the University College London School of Pharmacy to test a range of herbal products on sale in the UK. They bought over 70 herbal products from various high street stores and internet retailers. Some of the products were ‘THR’ (traditional herbal registration) herbal medicines, and some were marketed as food supplements. They then analyzed their chemistry to see whether each one really contained what the label says. The three popular herbal remedies we tested were:-
- Milk thistle (Silybum marianum),
- Ginkgo (Ginkgo biloba),
- Evening primrose (Oenothera).
The team at UCL used two different methods of analysis to verify the identity of these herbal products and extracts. High-performance thin-layer chromatography (HPTLC) is a sophisticated technique for the analysis of herbal products and is one of the most commonly used methods in the industry. HPTLC analysis creates a chemical fingerprint of the product which the researchers can then compare to an accepted reference standard for the herb. They look for a broad spectrum of ‘marker compounds’ these are the pharmacologically active and/or chemical constituents within a plant that can be used to verify its potency or identity. For complex samples or where additional confirmation is required, researchers often turn to ¹H nuclear magnetic resonance spectroscopy (¹H-NMR) which allows individual samples to be compared in detail against other samples or to the whole group.
In every THR product tested, the product contained what was claimed on the label. However, the food supplements showed a wide range of quality.
- Of the food supplement products labeled as Ginkgo, 8 out of 30 (27%) contained little or no ginkgo extract.
- 36% of the food supplement milk thistle products contained no detectable milk thistle. Although this is quite a small sample size it is still a startling result. Furthermore, in one case of milk thistle, unidentified adulterants suspected to be synthetic compounds were present in place of milk thistle.
- All of the evening primrose food products we tested did contain what the packet claimed.
The researchers concluded that their investigation shows that a regulatory system for herbal products, like the THR scheme, ensures that people have access to safe herbal medicine products. So, if you are considering buying herbal products then do look out for the THR mark– otherwise, you might not just be wasting your money, you might be consuming other, potentially dangerous, ingredients.
This is an interesting investigation. The researchers should be commended for it! However, I disagree with some of their conclusions. Here is why:
- The investigation merely tested the quality of the products and NOT THEIR SAFETY! To claim that the THR ensures access to safe herbal medicines is incorrect. A product might be of adequate quality but can still be unsafe. The THR only implies safety because the herbal has been used for years without problems being noted. This is not the same as ensuring that it is safe. A direct test of safety is usually not available.
- The recommendation to buy a product with a THR mark is also somewhat misleading. It implies that these products are effective. I fail to see convincing evidence that either MILK THISTLE, GINKGO, or EVENING PRIMROSE are effective for any disease or condition. Thus the responsible recommendation should, in my view, be to NOT buy them regardless of whether they are of good quality or not.
‘Spagyric’ is a so-called alternative medicine (SCAM) based on the alchemy of Paracelsus (1493-1541). Paracelsus borrowed the term from “separate” (spao) and “combine” (ageiro) to indicate that spagyric preparations are based on the “separation”, “extraction” and “recombination” of the active ingredients of a substance. Plant, mineral as well as animal source materials are used.
The production of spagyric remedies is based on a complex process of maceration and fermentation of a plant extract in alcohol. It takes place in dark, thick-walled glass flasks that are hermetically sealed and kept at a controlled temperature of 37 °C for 28 days. The tincture thus obtained is then decanted and the drug residue is removed from the solution, completely dried, and burned to ash to recover the inorganic components of the plant material. The ash is subsequently dissolved in the alcoholic solution of maceration, and the finished spagyric preparation is left for 12 days before use.
Spagyric is not the most popular of all SCAMs but it certainly does have a significant following. One enthusiast claims that “spagyric essences work on a vibrational level in their action upon the emotional/mind and physical spheres and can be employed in numerous situations. Most people seek help to relieve physical symptoms. Even so, it is often necessary to address the emotional and psychological aspects which may predispose the illness or imbalance. In an era where many people are experiencing life-changing events, the ability to transition smoothly is essential for well-being and vitality. Guidance and help are required to maintain homeostasis. These medicines can help the patient to understand the root cause of their illness and learn to regain control of their lives. Some medicine systems appear to be less effective than in previous times. It has been suggested that the energetic frequency of both the earth and human organism are changing. Therefore these systems may no longer be a vibrational match for the changing frequencies. Spagyric Medicine is designed to ‘tune in with’ these current frequencies. Research suggests that the Spagyric essences may instigate improved health by energetically influencing DNA.”
After reading such weird statements, I ask myself, is there any evidence that spagyric remedies work? In my search for robust studies, I was unsuccessful. There does not seem to be a single controlled study on the subject. However, there are fragmentary reports of a study initiated and conducted by a now largely unknown healer named Karl Hann von Weyhern.
Von Weyhern (1882 – 1954) had taken a few semesters of pharmacy and medicine in Freiburg but remained without a degree. In 1930, he became a member of the NSDAP (Hitler’s Nazi party) and in 1940 he joined the SS. Around 1935, he settled in Munich as a non-medical practitioner (Heilpraktiker), and Heinrich Himmler who has a soft spot for SCAM enlisted as one of his patients. By then von Weyhern had by then made a steep career in the Nazi hierarchy, and he managed to convince Himmler that his spagyric remedies could cure tuberculosis, which was still rampant at the time. They decided to carry out experiments in this regard in the Dachau concentration camp.
Thus, von Weyhern was allowed to test spagyric remedies on forcibly recruited concentration camp prisoners. These experiments lasted for about one year and included around 150 patients who, according to von Weyhern’s iridology diagnosis, suffered from tuberculosis. Half of them were treated with spagyric remedies and the others with conventional treatments. At the end of the experiment, 27 persons were reportedly released into everyday concentration camp life as ‘fit for work’. How many of the 150 prisoners lost their lives due to these experiments is not known. Von Weyhern never filed a final report. It is to be feared that the death toll was considerable. 
After the war, von Weyhern denied belonging to the SS, claimed that he had ‘sacrificed himself’ for his patients in the concentration camp, merely had to pay a fine, and was ‘denazified’ in 1948. Subsequently, he resumed his work as a ‘Heilpraktiker’ in Olching, a village near Dachau. 
Of course, these infamous experiments cannot be blamed on spagyric medicine. Yet, I feel they are nevertheless important, not least because they seem to reveal the only thing remotely resembling something like evidence.

The German Heilpraktiker (HP), a non-medically trained practitioner of so-called alternative medicine (SCAM), has repeatedly been the subject of my posts. In a nutshell: the profession was created by the Nazis and was originally destined to disappear within one generation. But this did not happen, and today there are ~100 000 HPs who are allowed to treat almost any condition without mandatory training or experience. Many HP schools exist but you can also become an HP without formal training.
Now a report has been published by undercover journalists investigating these HP schools in Germany. Here I have summarized a few crucial passages for you (if you read German, I strongly recommend reading the original article):
There are more than 150 HP schools in Germany. On average, training costs several thousand euros. There is no uniform and state regulation for the training. The curricula are mostly created by the schools themselves.
In addition to medical and psychological content, the schools often offer seminars that are not based on scientific knowledge. The curricula sometimes include courses such as astrology, homeopathy, or so-called quantum healing. HP organizations give indeed training guidelines. However, these are not met by about 83% of the schools.
The students were isolated at the HP school from their environment and urged to break off contact with their families. “Without us you are nothing. That came so often and I then, unfortunately, believed in it, because I was alone. If I had had no one else from school, then I would really have been completely alone,” explains a former student in an interview. “During that time, I also thought for the first time: Are we in some kind of cult here?
The school’s principal rejects the cult accusation: “We have been confronted with the allegation that we are a cult for some time and have always dealt with it very openly because we are not a cult. The principal also denies other accusations made by former students, saying that the allegations of suggestion, coercion, compulsion, or sweeping statements are simply false. He said he would be happy to face them “in a personal conversation outside the public eye to answer their questions.”
In order to get to the bottom of the treatment methods, the reporter also had herself treated by the principal of the school in an undercover self-experiment. In the first session, she determined that the reporter’s sciatica had been passed on to her by her mother, which is why she should sever her ties with her. In the second session, she recommended that she no longer visit her cancer-stricken grandfather. When the principal learned that the ill grandpa was of the zodiac sign Cancer, she concluded, “Cancer gets cancer.” The cancer, she said, was due to the fact that he had done nothing for his soul. And further, the patient runs the risk of adopting the grandfather’s cancer symptoms when she visits him.
The Hamburg health authority, which is listed as a “supervisory authority” on the school’s homepage, explains in response to an inquiry that no official supervision exists for HP schools. To obtain permission for opening a school, no training is necessary. Neither possible training courses nor institutions offering such training courses are regulated by the state.
The journalist also asked the Federal Health Ministry whether it sees the need for action and legal control. The Ministry’s response was evasive: “If necessary,” the HP law should be reformed in the future.
This is shocking news for many Germans who believe that HPs are well-trained healthcare professionals. However, those who have read my recently published book cannot be surprised. Poor training is only one of a myriad of deficits of HPs. It is time that the government realizes that the current is unacceptable and endangers public health. It is time, in other words, that the government does something about the HP profession.
