Updated Edition!
I was alerted to an interview published in an anthroposophical journal with Prof. Dr. med. Harald Matthes. He is the clinical director of the ‘Gemeinschaftskrankenhauses Havelhöhe‘, a hospital of anthroposophic medicine in Berlin where apparently some COVID-19 patients are presently being treated. Anthroposophic medicine is a medical cult created by the mystic, Rudolf Steiner, about 100 years ago that lacks a basis in science, facts or common sense. Here is the two passages from that interview that I find most interesting (my translation/explanation is below):
Es gibt bisher kein spezifisches Covid-19 Medikament aus der konventionellen Medizin. Remdesivir führt in Studien zu keinem signifikant verbesserten Überleben, sondern lediglich zu einer milden Symptomreduktion. Die anfänglich große Studie vor allem an Universitätskliniken mit Hydrochloroquin und Azithromycin erbrachte sogar eine Steigerung der Todesrate. Daher haben anthroposophische Therapiekonzepte mit Steigerung der Selbstheilungskräfte eine große Bedeutung erfahren. Wichtige anthroposophische Arzneimittel waren dabei das Eisen als Meteoreisen oder als Ferrum metallicum praep., der Phosphor, das Stibium sowie das Cardiodoron® und Pneumodoron®, aber auch Bryonia (Zaunrübe) und Tartarus stibiatus (Brechweinstein). Die Erfolge waren sehr gut, da in Havelhöhe bisher kein Covid-19 Patient verstorben ist, bei einer sonstigen Sterblichkeit von ca. 30% aller Covid-19-Intensivpatienten…
100 Jahre Bazillentheorie und die Dominanz eines pathogenetischen Medizinkonzeptes haben zu der von Rudolf Steiner bereits 1909 vorausgesagten Tyrannei im Sozialen geführt. Der Mensch hat ein Mikrobiom und Virom, das unverzichtbar für seine Immunität ist und von der Quantität mächtiger als der Mensch selbst (Mikrobiom 1014 Bakterien mit ca. 1200 Spezies z.B. im Darm bei nur 1012 Körperzellen).
Matthes explains that, so far, no medication has been demonstrated to be effective against COVID-19 infections. Then he continues: “This is the reason why anthroposophic therapies which increase the self-healing powers have gained great importance”, and names the treatments used in his hospital:
- Meteoric Iron (a highly diluted anthroposophic remedy based on iron from meteors),
- Ferrum metallicum praep. (a homeopathic/anthroposophic remedy based on iron),
- Phosphor (a homeopathic remedy based on phosphor),
- Stibium (a homeopathic remedy based on antimony),
- Cardiodoron (a herbal mixture used in anthroposophical medicine),
- Pneumodoron (a herbal mixture used in anthroposophical medicine containing).
Matthes also affirms (my translation):
“The success has so far been very good, since no COVID-19-patient has died in Havelhöhe – with a normal mortality of about 30% of COID_19 patients in intensive care…
100 years of germ theory and the dominance of a pathogenetic concept of medicine have led to the tyranny in the social sphere predicted by Rudolf Steiner as early as 1909. Humans have a microbiome and virom that is indispensable for their immunity and more powerful in quantity than humans themselves (microbiome 1014 bacteria with about 1200 species e.g. in the intestine with only 1012 somatic cells)…”

The first 4 remedies listed above are highly diluted and contain no active molecules. The last two are less diluted and might therefore contain a few active molecules but in sub-therapeutic doses. Crucially, none of the remedies have been shown to be effective for any condition.
The germ theory of disease which Matthes mentions is, of course, a bit more than a ‘theory’; it is the accepted scientific explanation for many diseases, including COVID-19.
I have cold sweats when I think of anthroposophical doctors who seem to take it less than seriously, while treating desperately ill COVID-19 patients. If I were allowed to ask just three questions to Matthes, I think, it would be these:
- How did you obtain fully informed consent from your patients, including the fact that your remedies are unproven and implausible?
- If you think your results are so good, are you monitoring them closely to publish them urgently, so that other centres might learn from them?
- Do you feel it is ethical to promote unprovn treatments during a health crisis via a publicly available interview before your results have been formally assessed and published?
Acupuncture-moxibustion therapy (AMT) is a so-called alternative medicine (SCAM) that has been used for centuries in treatment of numerous diseases. Some enthusiasts even seem to advocate it for chemotherapy-induced leukopenia (CIL) The purpose of this review was to evaluate the efficacy and safety of acupuncture-moxibustion therapy in treating CIL.
Relevant studies were searched in 9 databases up to September 19, 2020. Two reviewers independently screened the studies for eligibility, extracted data, and assessed the methodological quality of selected studies. Meta-analysis of the pooled mean difference (MD) and risk ratio (RR) with their respective 95% confidence intervals (CI) were calculated.
Seventeen studies (1206 patients) were included, and the overall quality of the included studies was moderate. In comparison with medical therapy, AMT has a better clinical efficacy for CIL (RR, 1.24; 95% CI, 1.17-1.32; P < 0.00001) and presents advantages in increasing leukocyte count (MD, 1.10; 95% CI, 0.67-1.53; P < 0.00001). Also, the statistical results show that AMT performs better in improving the CIL patients’ Karnofsky performance score (MD, 5.92; 95% CI, 3.03-8.81; P < 0.00001).
The authors concluded that this systematic review and meta-analysis provides updated evidence that AMT is a safe and effective alternative for the patients who suffered from CIL.
A CIL is a serious complication. If I ever were afflicted by it, I would swiftly send any acupuncturist approaching my sickbed packing.
But this is not an evidence-based attitude!!!, I hear some TCM-fans mutter. What more do you want that a systematic review showing it works?
I beg to differ. Why? Because the ‘evidence’ is hardly what critical thinkers can accept as evidence. Have a look at the list of the primary studies included in this review:

Notice anything peculiar?
- The studies are all from China where data fabrication was reported to be rife.
- They are mostly unavailable for checking (why the published adds links that go nowhere is beyond me).
- Many do not look at all like randomised clinical trials (which, according to the authors, was an inclusion criterion).
- Many do not look as though their primary endpoint was the leukocyte count (which, according to the authors, was another inclusion criterion).
Intriguingly, the authors conclude that AMT is not just effective but also ‘safe’. How do they know? According to their own data extraction table, most studies failed to mention adverse effects. And how exactly is acupuncture supposed to increase my leukocyte count? Here is what the authors offer as a mode of action:
I think it is high time that we stop tolerating that the medical literature gets polluted with such nonsense (helped, of course, by journals that are beyond the pale) – someone might actually believe it, in which case it would surely hasten the death of vulnerable patients.
Two Dutch scientists tested the hypothesis that spiritual training operates like other self‐enhancement tools and contribute to a contingent self‐worth that depends on one’s spiritual accomplishments.
In three studies, a measure of spiritual superiority showed good internal consistency and discriminant validity. Spiritual superiority was distinctly related to spiritual contingency of self‐worth, illustrating that the self‐enhancement function of spirituality is similar to other contingency domains. It was correlated with self‐esteem and, more strongly, with communal narcissism, corroborating the notion of spiritual narcissism. Spiritual superiority scores were consistently higher among energetically trained participants than mindfulness trainees and were associated with supernatural overconfidence and self‐ascribed spiritual guidance.
Spititual superiority is claimed to be a measure to which degree people feel superior to those “who lack the spiritual wisdom they ascribe to themselves.” The measure’s questionnaires ask people to respond on a scale of 1 to 7 to a series of statements. Example statements include “I am more in touch with my senses than most others,” “I am more aware of what is between heaven and earth than most people,” and “The world would be a better place if others too had the insights that I have now.”
Essentially, the studies suggest that the use of spiritual training techniques such as
- energy healing,
- aura reading,
- mindfulness,
- and meditation
correlate with both narcissism and “spiritual superiority.” By encouraging self-compassion and non-judgmental self-acceptance, spiritual training should presumably make people less concerned with such things. Yet, it seems to have the opposite effect: it enhances the need to feel “more successful, more respected or more loved.”
The authors argue that, “like religiosity, spirituality is a domain that seems like a safe and secure investment for self-worth. One’s spiritual attainments allow lots of room for wishful thinking, thus easily lending themselves to the grip of the self-enhancement motive.” And because spiritual matters are generally “elusive to external objective standards,” that makes them a “suitable domain for illusory beliefs about one’s superiority.”
The causal arrow might work in both directions, the authors argue:
- People use spirituality as a self-esteem booster. It allows them to see themselves as special, and they can achieve progress in the spiritual domain relatively easily, as there are no objectively measurable outcomes.
- Spiritual training attracts people who already feel superior. And the “extensive exploration of one’s personal thoughts and feelings” that spiritual training encourages “may be particularly appealing” to narcissists.
The authors concluded as follows: “The phenomenon of spiritual superiority is widely recognized, both by authors who have written about it and by lay people who have felt the condescension of spiritually ‘enlightened’ others. At the same time, it has not yet been empirically studied before. We developed a measure of spiritual superiority, along with scales for self-proclaimed spiritual guidance, supernatural overconfidence, and spiritual contingency of self-worth. We have demonstrated their reliability and we have presented initial findings on correlations with other variables and differences between types of spiritual training, corroborating the validity of our scales. Our results and our theoretical analysis can stimulate further research into this phenomenon. In the applied domain, this could reveal more insights into the effects of spiritual training, and possibly the conditions and personality characteristics that facilitate genuine spiritual growth. More importantly, our results reveal the sovereignty and tenacity of the self-enhancement motive, showing its operation in a context designed to quiet the ego. This can be understood in terms of dual process models, assuming that self-enhancement is an automatic tendency whereas mindful awareness requires thoughtful processes. Our results thus extend the current body of knowledge on self-enhancement, by including a domain in which self-superiority might be least expected.”
Some consumers believe that research is by definition reliable, and patients are even more prone to this error. When they read or hear that ‘RESEARCH HAS SHOWN…’ or that ‘A RECENT STUDY HAS DEMONSTRATED…’, they usually trust the statements that follow. But is this trust in research and researchers justified? During 25 years that I have been involved in so-called alternative medicine (SCAM), I have encountered numerous instances which make me doubt. In this post, I will briefly discuss some the many ways in which consumers can be mislead by apparently sound evidence (for an explanation as to what is and what isn’t evidence, see here).
ABSENCE OF EVIDENCE
I have just finished reading a book by a German Heilpraktiker that is entirely dedicated to SCAM. In it, the author makes hundreds of statements and presents them as evidence-based facts. To many lay people or consumers, this will look convincing, I am sure. Yet, it has one fatal defect: the author fails to offer any real evidence that would back up his statements. The only references provided were those of other books which are equally evidence-free. This popular technique of making unsupported claims allows the author to make assertions without any checks and balances. A lay person is usually unable or unwilling to differentiate such fabulations from evidence, and this technique is thus easy and poular for misleading us about SCAM.
FAKE-EVIDENCE
On this blog, we have encountered this phenomenon ad nauseam: a commentator makes a claim and supports it with some seemingly sound evidence, often from well-respected sources. The few of us who bother to read the referenced articles quickly discover that they do not say what the commentator claimed. This method relies on the reader beeing easily bowled over by some pretend-evidence. As many consumers cannot be bothered to look beyond the smokescreen supplied by such pretenders, the method usually works surprisingly well.
An example: Vidatox is a homeopathic cancer ‘cure’ from Cuba. The Vidatox website clains that it is effective for many cancers. Considering how sensational this claim is, one would expect to find plenty of published articles on Vidatox. However, a Medline search resulted in one paper on the subject. Its authors drew the following conclusion: Our results suggest that the concentration of Vidatox used in the present study has not anti-neoplastic effects and care must be taken in hiring Vidatox in patients with HCC.
The question one often has to ask is this: where is the line between misleading research and fraud?
SURVEYS
There is no area in healthcare that produces more surveys than SCAM. About 500 surveys are published every year! This ‘survey-mania’ has a purpose: it promotes a positive message about SCAM which hypothesis-testing research rarely does.
For a typical SCAM survey, a team of enthusiastic researchers might put together a few questions and design a questionnaire to find out what percentage of a group of individuals have tried SCAM in the past. Subsequently, the investigators might get one or two hundred responses. They then calculate simple descriptive statistics and demonstrate that xy % use SCAM. This finding eventually gets published in one of the many third-rate SCAM journals. The implication then is that, if SCAM is so popular, it must be good, and if it’s good, the public purse should pay for it. Few consumers would realise that this conclusion is little more that a fallacious appeal to popularity.
AVOIDING THE QUESTION
Another popular way of SCAM researchers to mislead the public is to avoid the research questions that matter. For instance, few experts would deny that one of the most urgent issues in chiropractic relates to the risk of spinal manipulations. One would therefore expect that a sizable proportion of the currently published chiropractic research is dedicated to it. Yet, the opposite is the case. Medline currently lists more than 3 000 papers on ‘chiropractic’, but only 17 on ‘chiropractic, harm’.
PILOT-STUDIES
A pilot study is a small scale preliminary study conducted in order to evaluate feasibility, time, cost, adverse events, and improve upon the study design prior to performance of a full-scale research project. Yet, the elementary preconditions are not fulfilled by the plethora of SCAM pilot studies that are currently being published. True pilot studies of SCAM are, in fact, very rare. The reason for the abundance of pseudo-pilots is obvious: they can easily be interpreted as showing encouragingly positive results for whatever SCAM is being tested. Subsequently, SCAM proponents can mislead the public by claiming that there are plenty of positive studies and therefore their SCAM is supported by sound evidence.
‘SAFE‘ STUDY-DESIGNS
As regularly mentioned on this blog, there are several ways to design a study such that the risk of producing a negative result is minimal. The most popular one in SCAM research is the ‘A+B versus B’ design. In this study, for instance, cancer patients who were suffering from fatigue were randomised to receive usual care or usual care plus regular acupuncture. The researchers then monitored the patients’ experience of fatigue and found that the acupuncture group did better than the control group. The effect was statistically significant, and an editorial in the journal where it was published called this evidence “compelling”. Due to a cleverly over-stated press-release, news spread fast, and the study was celebrated worldwide as a major breakthrough in cancer-care.
Imagine you have an amount of money A and your friend owns the same sum plus another amount B. Who has more money? Simple, it is, of course your friend: A+B will always be more than A [unless B is a negative amount]. For the same reason, such “pragmatic” trials will always generate positive results [unless the treatment in question does actual harm]. Treatment as usual plus acupuncture is more than treatment as usual alone, and the former is therefore more than likely to produce a better result. This will be true, even if acupuncture is a pure placebo – after all, a placebo is more than nothing, and the placebo effect will impact on the outcome, particularly if we are dealing with a highly subjective symptom such as fatigue.
A more obvious method for generating false positive results is to omit blinding. The purpose of blinding the patient, the therapist and the evaluator of the group allocation in clinical trials is to make sure that expectation is not a contributor to the result. Expectation might not move mountains, but it can certainly influence the result of a clinical trial. Patients who hope for a cure regularly do get better, even if the therapy they receive is useless, and therapists as well as evaluators of the outcomes tend to view the results through rose-tinted spectacles, if they have preconceived ideas about the experimental treatment.
Failure to randomise is another source of bias which can mislead us. If we allow patients or trialists to select or chose which patients receive the experimental and which get the control-treatment, it is likely that the two groups differ in a number of variables. Some of these variables might, in turn, impact on the outcome. If, for instance, doctors allocate their patients to the experimental and control groups, they might select those who will respond to the former and those who don’t to the latter. This may not happen with intent but through intuition or instinct: responsible health care professionals want those patients who, in their experience, have the best chances to benefit from a given treatment to receive that treatment. Only randomisation can, when done properly, make sure we are comparing comparable groups of patients. Non-randomisation can easily generate false-positive findings.
It is also possible to mislead people with studies which do not test whether an experimental treatment is superior to another one (often called superiority trials), but which assess whether it is equivalent to a therapy that is generally accepted to be effective. The idea is that, if both treatments produce similarly positive results, both must be effective. Such trials are called non-superiority or equivalence trials, and they offer a wide range of possibilities for misleading us. If, for example, such a trial has not enough patients, it might show no difference where, in fact, there is one. Let’s consider a simple, hypothetical example: someone comes up with the idea to compare antibiotics to acupuncture as treatments of bacterial pneumonia in elderly patients. The researchers recruit 10 patients for each group, and the results reveal that, in one group, 2 patients died, while, in the other, the number was 3. The statistical tests show that the difference of just one patient is not statistically significant, and the authors therefore conclude that acupuncture is just as good for bacterial infections as antibiotics.
Even trickier is the option to under-dose the treatment given to the control group in an equivalence trial. In the above example, the investigators might subsequently recruit hundreds of patients in an attempt to overcome the criticism of their first study; they then decide to administer a sub-therapeutic dose of the antibiotic in the control group. The results would then seemingly confirm the researchers’ initial finding, namely that acupuncture is as good as the antibiotic for pneumonia. Acupuncturists might then claim that their treatment has been proven in a very large randomised clinical trial to be effective for treating this condition. People who do not happen to know the correct dose of the antibiotic could easily be fooled into believing them.
Obviously, the results would be more impressive, if the control group in an equivalence trial received a therapy which is not just ineffective but actually harmful. In such a scenario, even the most useless SCAM would appear to be effective simply because it is less harmful than the comparator.
A variation of this theme is the plethora of controlled clinical trials in SCAM which compare one unproven therapy to another unproven treatment. Perdicatbly, the results would often indicate that there is no difference in the clinical outcome experienced by the patients in the two groups. Enthusiastic SCAM researchers then tend to conclude that this proves both treatments to be equally effective. The more likely conclusion, however, is that both are equally useless.
Another technique for misleading the public is to draw conclusions which are not supported by the data. Imagine you have generated squarely negative data with a trial of homeopathy. As an enthusiast of homeopathy, you are far from happy with your own findings; in addition you might have a sponsor who puts pressure on you. What can you do? The solution is simple: you only need to highlight at least one positive message in the published article. In the case of homeopathy, you could, for instance, make a major issue about the fact that the treatment was remarkably safe and cheap: not a single patient died, most were very pleased with the treatment which was not even very expensive.
OMISSION
A further popular method for misleading the public is the outright omission findings that SCAM researchers do not like. If the aim is that the public believe the myth that all SCAM is free of side-effects, SCAM researchers only need to omit reporting them in clinical trials. On this blog, I have alerted my readers time and time again to this common phenomenon. We even assessed it in a systematic review. Sixty RCTs of chiropractic were included. Twenty-nine RCTs did not mention adverse effects at all. Sixteen RCTs reported that no adverse effects had occurred. Complete information on incidence, severity, duration, frequency and method of reporting of adverse effects was included in only one RCT.
Most trails have many outcome measures; for instance, a study of acupuncture for pain-control might quantify pain in half a dozen different ways, it might also measure the length of the treatment until pain has subsided, the amount of medication the patients took in addition to receiving acupuncture, the days off work because of pain, the partner’s impression of the patient’s health status, the quality of life of the patient, the frequency of sleep being disrupted by pain etc. If the researchers then evaluate all the results, they are likely to find that one or two of them have changed in the direction they wanted (especially, if they also include half a dozen different time points at which these variables are quatified). This can well be a chance finding: with the typical statistical tests, one in 20 outcome measures would produce a significant result purely by chance. In order to mislead us, the researchers only need to “forget” about all the negative results and focus their publication on the ones which by chance have come out as they had hoped.
FRAUD
When it come to fraud, there is more to chose from than one would have ever wished for. We and others have, for example, shown that Chinese trials of acupuncture hardly ever produce a negative finding. In other words, one does not need to read the paper, one already knows that it is positive – even more extreme: one does not need to conduct the study, one already knows the result before the research has started. This strange phenomenon indicates that something is amiss with Chinese acupuncture research. This suspicion was even confirmed by a team of Chinese scientists. In this systematic review, all randomized controlled trials (RCTs) of acupuncture published in Chinese journals were identified by a team of Chinese scientists. A total of 840 RCTs were found, including 727 RCTs comparing acupuncture with conventional treatment, 51 RCTs with no treatment controls, and 62 RCTs with sham-acupuncture controls. Among theses 840 RCTs, 838 studies (99.8%) reported positive results from primary outcomes and two trials (0.2%) reported negative results. The percentages of RCTs concealment of the information on withdraws or sample size calculations were 43.7%, 5.9%, 4.9%, 9.9%, and 1.7% respectively. The authors concluded that publication bias might be major issue in RCTs on acupuncture published in Chinese journals reported, which is related to high risk of bias. We suggest that all trials should be prospectively registered in international trial registry in future.
A survey of clinical trials in China has revealed fraudulent practice on a massive scale. China’s food and drug regulator carried out a one-year review of clinical trials. They concluded that more than 80 percent of clinical data is “fabricated“. The review evaluated data from 1,622 clinical trial programs of new pharmaceutical drugs awaiting regulator approval for mass production. Officials are now warning that further evidence malpractice could still emerge in the scandal.
I hasten to add that fraud in SCAM research is certainly not confined to China. On this blog, you will find plenty of evidence for this statement, I am sure.
CONCLUSION
Research is obviously necessary, if we want to answer the many open questions in SCAM. But sadly, not all research is reliable and much of SCAM research is misleading. Therefore, it is always necessary to be on the alert and apply all the skills of critical evaluation we can muster.
I very rarely discuss animal experiments on this blog. Their applicability to clinical situations in human patients is almost invariably doubtful. Of course, this does not mean that they cannot be important; on the contrary, they may point the way towards relevant research and help formulate hypotheses.
This study might be exceptionally relevant in this way. To investigate the safety and efficacy of megadose sodium ascorbate in sepsis, sheep were instrumented with pulmonary and renal artery flow-probes, and laser-Doppler and oxygen-sensing probes in the kidney. Conscious sheep received an infusion of live Escherichia coli for 31 hours. At 23.5 hours of sepsis, sheep received fluid resuscitation (30 mL/kg, Hartmann solution) and were randomized to IV sodium ascorbate (0.5 g/kg over 0.5 hr + 0.5 g/kg/hr for 6.5 hr; n = 5) or vehicle (n = 5). Norepinephrine was titrated to restore mean arterial pressure to baseline values (~80 mm Hg).
Sepsis-induced fever (41.4 ± 0.2°C; mean ± SE), tachycardia (141 ± 2 beats/min), and a marked deterioration in clinical condition in all cases. Mean arterial pressure (86 ± 1 to 67 ± 2 mm Hg), arterial PO2 (102.1 ± 3.3 to 80.5 ± 3.4 mm Hg), and renal medullary tissue PO2 (41 ± 5 to 24 ± 2 mm Hg) decreased, and plasma creatinine doubled (71 ± 2 to 144 ± 15 µmol/L) (all p < 0.01).
Direct observation indicated that in all animals, sodium ascorbate dramatically improved the clinical state, from malaise and lethargy to a responsive, alert state within 3 hours. Body temperature (39.3 ± 0.3°C), heart rate (99.7 ± 3 beats/min), and plasma creatinine (32.6 ± 5.8 µmol/L) all decreased. Arterial (96.5 ± 2.5 mm Hg) and renal medullary PO2 (48 ± 5 mm Hg) increased. The norepinephrine dose was decreased, to zero in four of five sheep, whereas mean arterial pressure increased (to 83 ± 2 mm Hg).
These physiologic findings were subsequently confirmed in a coronavirus patient with shock by compassionate use of 60 g of sodium ascorbate over 7 hours.
The authors concluded that IV megadose sodium ascorbate reversed the pathophysiological and behavioral responses to Gram-negative sepsis without adverse side effects. Clinical studies are required to determine if such a dose has similar benefits in septic patients.
As always with animal experiments, it is difficult to extrapolate to clinical situations in human patients. However, the fact that the authors did try their approach on one COVID-19 patient is encouraging. I agree with their conclusion that careful human studies are now required.
The amount of different so-called alternative medicines (SCAMs) that are being tried or promoted against COVID-19 is legion. Anything really from vitamins to herbal remedies, homeopathics to chiropractic. In fact, it is hard these days to find a SCAM that is not touted for COVID-19.
This study aimed to evaluate if a dietary supplement of quercetin (a polyphenol contained in many fruit and vegetables), vitamin C and bromelain (a proteolytic enzyme contained in pineapple) could be protective against coronavirus infections.
In the verum group, a supplement containing
- 500mg of quercetin,
- 500mg of vitamin C,
- 50mg of bromelain (QCB)
was administered daily in 2 divided doses for 71 healthcare workers working in areas with high risk of COVID-19, whereas 42 were the control group who received no supplements. The maximum period of follow-up was 120 days. Termination of QCB use prematurely or having a coronavirus infection was the end of a volunteer’s study participation. A rapid diagnostic test was used to detect immunoglobulin positivity.
Graphic demonstrated survival without COVID-19 during follow up time between groups
A total of 113 persons were included. No significant difference were detected between groups at baseline. Mean age of QCB group was 39.0 ± 8.8 years and control group was 32.9 ± 8.7. Average follow-up period for the QCB group was 113 days, and for the control group, 118 days. During the follow-up period, 1 healthcare worker in the QCB group and 9 out in 42 in control group contracted COVID-19. One case was asymptomatic, while others were not. Transmission risk hazard ratio of participants who did not receive QCB was 12.04 (95% Confidence interval= 1.26-115.06, P = 0.031). No significant effect of gender, smoking, antihypertensive medication exposure and having chronic disease on rate of transmission. The authors concluded that this study revealed that QCB was protective for healthcare workers.
The sudy is so poorly written and reported that I had trouble making sense of it. In fact, I first thought it was a fake. Then I saw this note:
Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed.
If the results are for real (because of the small sample size, the lack of a placebo-control, dozens of potential confounders, etc., the findings could easily false-positive), they would merit urgent replication in a larger, more rigorous trial.
And meanwhile?
Meanwhile I would be very sceptical about the validity of the results. The paper (it really is just a submission for publication in the Lancet; I am not even sure that it will be officially published and I don’t quite see why it is being made available to the public in this way) is too flimsy for words. Despite these warnings, it is likely that many consumers will fall for the claim that QCB was protective for healthcare workers.
In these pre-Xmas days, many homes will smell of cinnamon. It’s certainly a wonderful spice for creating an atmosphere. But ther are also other uses for ciannamon.
Current treatments for overactive bladder (OAB) have limited efficacy, low persistence and a high rate of adverse events commonly leading to treatment cessation in clinical practice. Clinicians in Asia commonly use traditional Chinese medicine as an alternative for OAB treatment despite it having uncertain efficacy and safety. To evaluate the efficacy and safety of cinnamon patch (CP) treatment for alleviating symptoms of OAB, this double-blind randomized, placebo-controlled trial was conducted.
The 6-week study was conducted in an outpatient setting; 66 subjects diagnosed as having OAB were enrolled and treated with a placebo (n=33) or CP (n=33). The OAB symptom score (OABSS) was selected as the primary end point, and a patient perception of bladder condition (PPBC), an urgency severity scale (USS), and post-voiding residual urine (PVR) volume were selected as secondary end points.
In total, 66 participants (40 women and 26 men), 60 years of age, were included in the intention-to-treat analyses. Baseline characteristics were comparable between the CP and placebo groups. Treatment with a CP showed statistically significant differences in reductions in OABSS scores, PPBC scores, and USS scores.
The authors concluded that compared to a placebo, treatment with CP might be considered an effective and safe complementary therapy for OAB. Further studies employing a positive control, different dosage forms, larger sample sizes, and longer treatment periods are warranted.
Cinnamon (Cinnamomum zeylanicum and Cinnamon cassia)belongs to the Lauraceae family. It contains manganese, iron, dietary fiber, and calcium as well as cinnamaldehyde, cinnamic acid, cinnamate, and numerous other components such as polyphenols and antioxidant, anti-inflammatory, antidiabetic, antimicrobial, anticancer effects. Several reports have dealt with the numerous properties of cinnamon in the forms of bark, essential oils, bark powder, and phenolic compounds, and each of these properties can play a key role in human health.
The new study is interesting and prompts me to ponder:
- Do the pharmacologically active ingredients of cinnamon pass the skin barrier in sufficient amounts to have any effect at all? Or perhaps it was the scent? In which case, this would have been a study of aromatherapy.
- Considering the typical scent of cinnamon, I find it hard to imagine that this study was truly double blind.
- Cinnamon is alleged to have antimicrobial, antiviral, antifungal, antioxidant, antitumor, antihypertensive, antilipemic, antidiabetic, gastroprotective, and immunomodulatory effects. I do wonder which, if any, of these are responsible for the observed clinical results of this trial.
- Cinnamon is known to sometimes lead to allergic reactions. I wonder whether this could be a problem when it is applied in patches.
So, for the time being, I think, I prefere cinnamon, the spice, to cinnamon, the medicine.
In so-called alternative medicine (SCAM), we have numerous diets that are either promoted for specific conditions or that are popular in a more general sense. Meat-free forms of nutrition can perhaps not be characterised as SCAM, but they are certainly popular with consumers as well as practitioners of SCAM. It is often said that meat-free diets are healthy, but few entusiasts like to consider that it might be associated with health risks.
This study tested whether vegetarianism and veganism are risk factors for bone factures in a prospective cohort with a large proportion of non-meat eaters.
In EPIC-Oxford, dietary information was collected at baseline (1993–2001) and at follow-up (≈ 2010). Participants were categorised into four diet groups at both time points (with 29,380 meat eaters, 8037 fish eaters, 15,499 vegetarians, and 1982 vegans at baseline in analyses of total fractures). Outcomes were identified through linkage to hospital records or death certificates until mid-2016. The risks were calculated of total (n = 3941) and site-specific fractures (arm, n = 566; wrist, n = 889; hip, n = 945; leg, n = 366; ankle, n = 520; other main sites, i.e. clavicle, rib, and vertebra, n = 467) by diet group over an average of 17.6 years of follow-up.
Compared with meat eaters and after adjustment for socio-economic factors, lifestyle confounders, and body mass index (BMI), the risks of hip fracture were higher in
- fish eaters (hazard ratio 1.26; 95% CI 1.02–1.54),
- vegetarians (1.25; 1.04–1.50),
- vegans (2.31; 1.66–3.22).
This was equivalent to rate differences of 2.9 (0.6–5.7), 2.9 (0.9–5.2), and 14.9 (7.9–24.5) more cases for every 1000 people over 10 years, respectively. The vegans also had higher risks of total (1.43; 1.20–1.70), leg (2.05; 1.23–3.41), and other main site fractures (1.59; 1.02–2.50) than meat eaters. Overall, the significant associations appeared to be stronger without adjustment for BMI and were slightly attenuated but remained significant with additional adjustment for dietary calcium and/or total protein. No significant differences were observed in risks of wrist or ankle fractures by diet group with or without BMI adjustment, nor for arm fractures after BMI adjustment.
The authors concluded that non-meat eaters, especially vegans, had higher risks of either total or some site-specific fractures, particularly hip fractures. This is the first prospective study of diet group with both total and multiple specific fracture sites in vegetarians and vegans, and the findings suggest that bone health in vegans requires further research.
The effect is by no means large, and I doubt that it will persuade many non-meat eaters to change their diet. However, perhaps the study can serve as a reminder that people who avoid meat might some lack essential nutrients and that they should therefore consider making sure that no deficiencies can develop.
Recent comments on this blog prompted me to look into a very strange therapeutic and diagnostic device used by some practitioners of so-called alternative medicine (SCAM):
The OBERON provides the most unique tool for scanning the various organs and systems of the physical body without having to make a medical or surgical intrusion. Developed by Russian scientists since the early 1990’s, the OBERON is the most revolutionary computer programmed invention available in the world today for analyzing and treating all the body’s organs and functions.
This device scans each organ or tissue on a cellular level. It compares the measurements to a database of thousands of referenced conditions and their diagnosis. OBERON uses a special emitter to modulate the carrier frequency for the cell communication and it uses special sensor trigger readers built into headphones to read the cells own signals.
OBERON finds out how stressed an organ is, and if there are any diseases developing, how much the cells are influenced by a specific disease, and which micro organisms and bacteria are in the area at the time of the scan.
BENEFITS OF THE OBERON:
Rebalances the body so that it can start to heal itself!
Makes intrusive and embarrassing examinations a THING OF THE PAST!!!!
Quick examination (in seconds) with immediate results
Replaces dozens of traditional diagnostic methods.
Finds weaknesses in the skeleton, organs, blood, tissue, etc.
There are no side effects, unpleasantness or injury after treatment
Bio-resonance META-therapy
A print out of the report on findings can be taken at the end of the session…
The method is based on an analysis of the brain stems electromagnetic waves which contain the complete information of the entire organism. This information is read by a sensor. A frequency transmitter aimed at the projection area of the brain stem stimulates this electromagnetic radiation.
Meta- Therapy repairs the organism using a diversity of modulated electromagnetic waves. This treatment stimulates the body’s own functions so that they solve the problem and it stimulates the immune defense and is a very good supplement or alternative to traditional treatment. The patient can follow on the screen how the organ progressively gets better, and afterwards one can take a new measurement showing the improvement…

Sounds fantastic?
Yes, indeed – fantastic as in fantasy!
Almost as much relation to reality as OBERON, king of the fairies in medieval literature.
The modern OBERON device is being used by infamous proponents of integrated medicine like Dr Julian Kenyon who already made an appearance on this blog. On his website, Kenyon published a paper in which he provides details about the OBERON. To a lay person, the sciency text might look like science; however, this impression would be false. The ‘study’ Kenyon mentioned is not on Medline. In fact, Dr Kenyon (former associate of the late George Lewith) has merely 4 Medline-listed papers:

And what about other researchers? Aren’t there ANY decent studies of the OBERON?
Not as far as I can see (if anyone does know of peer-reviewed research, please let me know).
So, what is the conclusion?
My conclusion is this:
There is no evidence that the OBERON does anything useful other than putting money in the bank accounts of those charlatans who use or manufacture it.
And what does that make Kenyon and all the other SCAM practitioners using the OBERON or similar devices?
I leave it to you to decide.
The Center for Science in the Public Interest*** (CSPI) announced its agreement with Boiron to improve the labeling on the homeopathic products manufactured by Boiron and sold under the Boiron or other private label brands. The agreement covers the labeling for over 50 homeopathic products.
On Boiron’s Oscillococcinum and two similar products, Boiron will substantially increase the prominence of the words “Homeopathic Medicine” on the front of the box and the disclaimer on the back of the box that says the product’s uses have not been evaluated by the Food and Drug Administration (FDA). These changes will make it easier for consumers to identify that the products are homeopathic products, and are not FDA approved over-the-counter medicines.
For all of the other homeopathic products manufactured by Boiron, consumers will receive much more information on the packages. In addition to increasing the prominence of the words “Homeopathic Medicine,” a new disclaimer in large and contrasting font will be added to the back of the package (endorsed by the American Association of Homeopathic Pharmacists) stating: “Claims based on traditional homeopathic practice, not accepted medical evidence, and not FDA evaluated.”…
“The labeling changes that Boiron has agreed to on all the products covered by the agreement will help consumers more clearly identify that these are homeopathic products and are not FDA approved over-the-counter medicines that have been scientifically proven to be safe and effective,” said CSPI litigation director Lisa Mankofsky. “In addition, the vast majority of the covered homeopathic products will bear a disclaimer clarifying that they are based on traditional homeopathic practice, not accepted medical evidence, and not FDA evaluated. We think that consumers will find this labeling change important when choosing a remedy. We encourage other manufacturers to similarly make their labels more transparent and clear for consumers.”
Bravo!
Clearly a step into the right direction!
But it’s a small step only. It is a long way short of what Dylan Evans suggestied in his book ‘Placebo‘, first published in 2004:
Warning: this product is a placebo. It will work only if you believe in homeopathy, and only for certain conditions such as pain and depression. Even then, it is not likely to be as powerful as orthodox drugs. You may get fewer side-effects from this treatment than from a drug, but you will probably also get less benefit.
***The Center for Science in the Public Interest is perhaps the oldest independent, science-based consumer advocacy organization with an impressive record of accomplishments and a clear and ambitious agenda for improving the food system to support healthy eating.
