The current Cochrane review of clinical trials testing the effectiveness of manipulation/mobilisation for neck pain concluded as follows:
Although support can be found for use of thoracic manipulation versus control for neck pain, function and QoL, results for cervical manipulation and mobilisation versus control are few and diverse. Publication bias cannot be ruled out. Research designed to protect against various biases is needed. Findings suggest that manipulation and mobilisation present similar results for every outcome at immediate/short/intermediate-term follow-up. Multiple cervical manipulation sessions may provide better pain relief and functional improvement than certain medications at immediate/intermediate/long-term follow-up. Since the risk of rare but serious adverse events for manipulation exists, further high-quality research focusing on mobilisation and comparing mobilisation or manipulation versus other treatment options is needed to guide clinicians in their optimal treatment choices.
Such a critical assessment must be tough for chiropractors who gain a substantial part of their income from treating such patients. What is the solution? Simple, convene a panel of chiros and issue recommendations that are more prone to stimulate their cash flow!
Exactly that seems to have just happened.
The purpose of the researchers was to develop best-practice recommendations for chiropractic management of adults with neck pain.
A steering committee of experts in chiropractic practice, education, and research drafted a set of recommendations based on the most current relevant clinical practice guidelines. Additional supportive literature was identified through targeted searches conducted by a health sciences librarian. A national panel of chiropractors representing expertise in practice, research, and teaching rated the recommendations using a modified Delphi process. The consensus process was conducted from August to November 2018. Fifty-six panelists rated the 50 statements and concepts and reached consensus on all statements within 3 rounds.
The statements and concepts covered aspects of the clinical encounter, ranging from informed consent through diagnosis, assessment, treatment planning and implementation, and concurrent management and referral for patients presenting with neck pain.
The authors concluded that these best-practice recommendations for chiropractic management of adults with neck pain are based on the best available scientific evidence. For uncomplicated neck pain, including neck pain with headache or radicular symptoms, chiropractic manipulation and multimodal care are recommended.
Let’s be clear what this amounts to: a panel of highly selected chiropractors (sponsored by a chiropractic organisation) has reached a consensus (and published it in a chiropractic) which allows them to continue to treat patients with neck pain.
Isn’t that just great?
Now let’s think ahead – what next?
I suggest the following:
- A panel of homeopaths recommending homeopathy.
- A panel of faith healers recommending faith healing.
- A panel of crystal healers recommending crystal healing.
- A panel of colon therapists recommending colonic irrigation.
- A panel of supplement manufacturers recommending to buy supplements.
I am sure you get the gist.
In the true Christmas spirit, I decided that I will give away presents to fans of homeopathy.
Here is the deal:
It is almost 2 years now that I asked all homeopaths, particularly those who believe that homeopathy works because it is ‘nano-medicine’, to answer the questions below:
- How (by what mechanism) does a nano-particle of coffee, for instance, affect the sleep centre in the brain to make the patient sleep? Or how does a nano-particle of the Berlin Wall or a duck liver affect anything at all in the human body?
- Most homeopathic remedies are consumed not as liquids but as ‘globuli’, i. e. tiny little pills made of lactose. They are prepared by spraying the liquid remedy on to them. The liquid subsequently evaporates. How is it that the information allegedly retained in the liquid does not evaporate with the diluent?
- The diluent usually is a water-alcohol mixture which inevitably contains impurities. In fact, a liquid C12 remedy contains dimensions more impurities than homeopathic stock. These impurities have, of course, also been vigorously shaken, i. e. potentised. How can we explain that their ‘potency’ has not been beefed up at each dilution step? Would this not necessitate a process where only some molecules in the diluent are agitated, while all the others remain absolutely still? How can we explain this concept?
- Some stock used in homeopathy is insoluble (for instance Berlin Wall). Such stock is not diluted but its concentration in the remedy is initially lowered by a process called ‘trituration’, a process which consists in grinding the source material in another solid material, usually lactose. Assuming that potentisation works in the way homeopaths think, how is information transferred from one solid material to another during trituration?
- Everything we drink is based on water containing molecules that have been inadvertently potentised in nature a million times and therefore should have hugely powerful effects on our bodies. How is it that we experience none of these effects each time we drink?
So far, I have not received any answers that stand up to scrutiny. Therefore, I now offer a present, free book on homeopathy,
to anyone who can provide a rational, scientifically sound answer to at least one of these questions. Just post your reply in the comments section. If it fulfils the above criteria, I will contact you, ask you for your postal address, and send you a free copy of my book.
Guest post by Richard Rasker
Almost two years ago, in March 2018, a group of 124 doctors and other medical professionals published an article in the French newspaper ‘Le Figaro’, warning the general public for the false promises, unproven claims and dangers of alternative medicine.
Homeopathy in particular is denounced as an unscientific belief in magic, utterly lacking in plausibility as well as in evidence of efficacy for any condition. Subjecting people to these kinds of unproven treatments is unethical, and may result in serious harm by delaying proper medical treatment. Also, homeopaths and other alternative practitioners often express anti-vaccine sentiments, endangering children by dissuading their parents from vaccination.
For these and several other reasons, these 124 medical professionals made an appeal for alternative and esoteric treatments to be excluded from the field of science-based medicine, and to stop reimbursement of homeopathic and other alternative treatments under France’s national health care insurance system.
In a somewhat belated response, French homeopaths are now filing no less than 63 disciplinary complaints with the French Medical Council against the signatories of the appeal in Le Figaro, apparently for “uncollegial behaviour” and “defiling medical ethics”. The homeopaths are represented by homeopathic doctor Daniel Scimeca, president of the French Federation of Homeopathic Societies, who also has close relations with Boiron laboratories, the biggest manufacturer of homeopathic products in the world.
At the time of this writing, 11 complaints have been adjudicated, resulting in 7 warnings, and 4 releases or dismissals. It is unclear how serious such a ‘warning’ should be taken, but it is clear that homeopaths are trying to punish real doctors for supporting and expressing an overwhelming scientific consensus, i.e. that there is no evidence whatsoever that homeopathy is actually good for anything.
And even though these French homeopaths do not resort to the sort of vile, underhanded media smear campaign perpetrated by the late Claus Fritzsche against Dr. Ernst, there are certain parallels – the most important of which is that proponents of unproven ‘medicine’ attempt to silence science-based criticism by unscientific means, instead of open discourse about the merits (or more precisely: the lack thereof) of their chosen profession.
I personally find it rather worrying that almost two-thirds of the complaints resulted in a slap on the wrist for the medical professional involved. Especially in a field that is so strongly dependent on both science and trust, well-founded criticism should be encouraged and made public, not punished and silenced.
At the heart of this story is Joseph Mercola, a dietary supplement entrepreneur and osteopath.
His website states that:
EVERYONE can benefit from Dr Mercola’s unparalleled knowledge. For expertise in alternative healthcare and high quality supplemental medicine, it’s hard to beat visionary Dr Joseph Mercola. The Chicago-based health wizard has his own website, Mercola.com (‘Take Control of Your Health’), but you can find so many of his health support products right here at Evolution Organics. Our customers swear by them. They love the diversity of the range, and that the products are priced affordably, meaning that everyone can benefit from Dr Mercola’s vast experience and unmatched know-how. And it’s not just men, women and children who can feel better ‘the Dr Mercola way’ – his brand includes health support products for pets, too.
However, an article in the Washington Post tells a different story; allow me to quote a few excerpts:
The National Vaccine Information Center was founded in 1982 by Barbara Loe Fisher, who has said that her son was injured by a vaccine. The group claimed credit this year for helping to defeat legislation in a dozen states that would have made it harder for parents to opt out of vaccinating their children. At the beginning of last year’s flu season, Fisher and Mercola appeared in a YouTube video urging people to be skeptical about flu shots. Mercola claimed that vaccines have been associated with “deaths and permanent neurological complications,” and he said vitamin D supplements were among “far more effective, less expensive and less risky alternatives.” … Fisher said in an interview that Mercola has asked for nothing in exchange for his donations and that the National Vaccine Information Center does not sell or advertise Mercola’s products on its site. “I do not take funding for a quid pro quo,” she said. “When [Mercola] called me, he said, ‘I admire your work. I’d like to help you.’ ” The center’s homepage, which the group says was visited more than 1.2 million times last year, displays Mercola.com’s logo. An affiliated website run by Fisher’s group refers numerous times to Mercola.com as one of the most popular health and wellness websites…
In recent years, the center has been at the forefront of a movement that has led some parents to forgo or delay immunizing their children against vaccine-preventable diseases such as measles… The Northern Virginia-based National Vaccine Information Center lists Mercola.com as a partner on its homepage and links to the website, where readers can learn about and purchase Mercola’s merchandise…Asked if his companies benefit from his donations to the anti-vaccine group, Mercola said in an email that “being an adversary to powerful industries is not a positive for a business like mine.” …
On this blog, I have repeatedly warned that many so-called alternative medicine (SCAM) practitioners recommend against vaccinations. Specifically implicated are:
- Physicians practising integrative medicine
- Doctors of anthroposophical medicine
We knew about the ‘ideology’ and the misinformation pushing SCAM-related anti-vaccination sentiments. The article in the Washington Post is a stark reminder of the financial interests behind all this. As a result, SCAM-use is associated with low vaccination-uptake (as we have discussed ad nauseam – see for instance here, here, here and here). Anyone who needs more information will find it by searching this blog. Anyone claiming that this is all my exaggeration might look at papers which have nothing to do with me (there are plenty more for those who are willing to conduct a Medline search):
- Lehrke P, Nuebling M, Hofmann F, Stoessel U. Attitudes of homeopathic physicians towards vaccination. Vaccine. 2001;19:4859–4864. doi: 10.1016/S0264-410X(01)00180-3. [PubMed]
- Halper J, Berger LR. Naturopaths and childhood immunizations: Heterodoxy among the unorthodox. Pediatrics. 1981;68:407–410. [PubMed]
- Colley F, Haas M. Attitudes on immunization: A survey of American chiropractors. Journal of Manipulative and Physiological Therapeutics. 1994;17:584–590. [PubMed]
This post is dedicated to all who claim that I never discuss anything positive about so-called alternative medicine (SCAM).
Autogenic training is a therapy developed in the 1920s by the German psychiatrist Johannes Heinrich Schultz (1884 – 1970). It is an auto-hypnotic relaxation technique popular in Germany but less so other countries. (The lack of international appreciation of autogenic training might be related to Schultz’ well-documented Nazi past. In 1935, he published an essay which supported compulsory sterilization of men to eliminate hereditary illnesses. Later he was appointed deputy director of the Göring Institute in Berlin. Through this institute, he had an active role in the extermination of mentally handicapped individuals in the framework of the ‘Aktion T4’, the Nazi’s infamous euthanasia programme.)
Autogenic training consists of mental exercises using instructions directed at different parts of the body to control bodily perceptions, such as ‘my right foot feels warm’ or ‘my left arm feels heavy’. Patients tend to report an intense sense of relaxation during and after autogenic training. Autogenic training is taught in a series of lessons by a qualified instructor.
Autogenic training should be practised regularly and does not require further supervision. It is thus an inexpensive therapy. The technique is claimed to help for a range of (mostly stress-related) conditions. However, the evidence from clinical trials is scarce and, not least due to methodological problems, less than convincing.
This systematic review was conducted to evaluate the effectiveness of autogenic training on stress responses. A total 11 studies were included in a meta-analysis. They showed that autogenic training decreased anxiety and depression, and increased the high frequency of heart rate variability as well as a reduction of anxiety score by 1.37 points (n=85, SMD=-1.37: 95% CI -2.07 to -0.67), in the studies on short-term intervention targeting healthy adults.For depression, a reduction was noted of the symptom score by 0.29 point (n=327, SMD=-0.29: 95% CI -0.50 to -0.07) in the studies on long term intervention targeting the patient group.
The authors concluded that autogenic training is effective for adults’ stress management, and nurses will be able to effectively perform autogenic training programs for workers’ stress relief at the workplace.
I cannot access the full article because it was published in Korean. Nevertheless, I feel that the conclusions are probably correct.
Because I know (most of) the primary studies and three of the RCTs are my own.
(Yet, some of my critics continue to claim that I never conducted any positive studies of SCAM)
If you had thought that HRH Prince Charles, soon to be King, would calm down regarding his royal bee under his alternative bonnet, you evidently were mistaken. In June 2019, he became the patron of the ‘Faculty of Homeopathy‘ the professional organisation of UK doctor homeopaths. And a few days ago, it has been announced that he now has also become the patron of the ‘College of Medicine and Integrated Health’ (CMIH). The College chair, Michael Dixon, was quoted stating: ‘This is a great honour and will support us as an organisation committed to taking medicine beyond drugs and procedures. This generous royal endorsement will enable us to be ever more ambitious in our mission to achieve a more compassionate and sustainable health service.”
I find it hard to be surprised by Charles’ latest move. After all, the CHIM is the direct successor of Charles’ ‘Foundation for Integrated Health‘ (FIH). When this bizarre organisation had to close in 2010 amid claims of fraud, money laundering and misuse of charity status (its chief executive later went to prison!), Dixon quickly organised the creation of the CMIH. Even though he was clearly involved, Charles was probably wise to keep his distance after the scandal. But now, almost a decade later, the dust has settled and he feels he can again patronise (= become a patron).
Dixon who was the medical director of the FIH did not go to prison; why should he? He had done nothing wrong! On the contrary, he collected another gong and even aspired to become the president of the ‘Royal College of General Practitioners‘. He failed, but his honours and appointments are still second to none:
- LVO (2015)
- OBE (2001)
- Visiting Professor University College of London
- Visiting Professor Westminster University
- Honorary Senior Fellow, HSMC Birmingham University
- Honorary Senior Lecturer Peninsula Medical School, Exeter
- Medical Advisor to the Prince of Wales
Don’t I just admire my ex-friend Michael?!
And so should you!!!
Just read the abstract of his study of spiritual healing. If you are not impressed by this work of beauty, there must be something wrong with you.
This study was designed to examine the effects of a healer seeing chronically ill patients in a large semirural practice. The 57 patients were allocated alternately either to receive ten weekly healing sessions or to become waiting-list controls. Two weeks after completion of ‘healing’ 22 (81%) of the 27 study patients thought their symptoms had improved and 15 of these thought they had improved substantially. Study patients scored better than controls on both measures of symptoms (P < 0.05, P < 0.01), on anxiety and depression ratings (P < 0.01, P < 0.05) and on general function measured by the Nottingham Health Profile (P < 0.01). Treatment differences were still evident three months later for one of the measures of symptom change (P < 0.05) and for both anxiety and depression ratings (P < 0.01, P < 0.05). The percentages of natural killer cells (CD16, CD56) did not change greatly in either group. These results suggest that healing may be an effective adjunct for the treatment of chronically ill patients presenting in general practice. They do not distinguish between any specific effects of spiritual healing and non-specific effects such as relaxation; for further investigation, randomized controlled trials will be needed.
Sorry, I digress – this should be about Charles, not Michael.
Now that he is patron of both the FoH and the CMIH, what might be next? As he has already tried his own brand of herbal remedies, I suggest the next launches a brand of homeopathics. What about
‘HRH – Hopeless Royal Homeopathy‘?
‘HRH – Hopeless Royal’s Homeopathy’
Well, suggest something better then!
There are no representative studies using a probability sample examining whether US physicians recommend so-called alternative medicines (SCAMs) to their patients. This article fills a void in the current literature for robust data on recommendations for SCAMs by office-based physicians in the US.
Descriptive statistics and multivariable regression analyses of physician-level data were from the 2012 Physician Induction Interview of the National Ambulatory Medical Care Survey (NAMCS PII), a nationally representative survey of office-based physicians. Weighted response rate among eligible physicians sampled for the 2012 NAMCS PII was 59.7%.
Recommendations by physicians to their patients were recorded for any SCAM, and the following individual SCAMs: massage therapy, herbs/nonvitamin supplements, chiropractic/osteopathic manipulation, yoga, acupuncture, and mind–body therapies.
Massage therapy was the most commonly recommended SCAM (30.4%), followed by chiropractic/osteopathic manipulation (27.1%), herbs/nonvitamin supplements (26.5%), yoga (25.6%), and acupuncture (22.4%). The most commonly recommended SCAMs by general/family practice physicians were chiropractic/osteopathic manipulation (54.0%) and massage therapy (52.6%). Of all U.S. physicians, 53.1% recommended at least one SCAM to patients during the previous 12 months. Multivariable analyses found physician’s sex, race, specialty, and U.S. region to be significant predictors of SCAMrecommendations. Female physicians were more likely than male physicians to recommend massage therapy, herbs/nonvitamin supplements, yoga, acupuncture, and mind–body therapies to patients. Psychiatrists, OB/GYNs, and paediatricians were all less likely to recommend chiropractic/osteopathic manipulation than general and family practitioners.
The authors concluded that, overall, more than half of office-based physicians recommended at least one SCAM to their patients. Female physicians recommended every individual SCAM at a higher rate than male physicians except for chiropractic and osteopathic manipulation. These findings may enable consumers, physicians, and medical schools to better understand potential differences in use of SCAMs with patients.
Yes, I know!
Who cares what type of SCAMs US physicians recommended to their patients 7 years ago?
And who knows what the true figures would have looked like, if the ~40% who did not respond would have been included?
Such surveys usually tell us little of relevance. What is worse, they are misused for exploiting the ‘appeal to authority’ fallacy which hold that, if physicians recommend SCAMs, they must be fine. That this is a fallacy becomes obvious, if we remind ourselves that US physicians also are the main cause for the current opioid crisis in the US (if physicians recommend opioids, they must be fine???).
More importantly, I think, this survey also suggests the following:
- 73% of US physicians do NOT recommend chiropractic/osteopathic manipulations.
- 73% of them do NOT recommend herbal medicine.
- 74% of them do NOT recommend yoga.
- 77% of them do NOT recommend acupuncture.
I wonder why!
Carbon 60 has recently been promoted by some commentators on this blog. Their claim seems to be that it is the best thing since sliced bread. So, what should we make of carbon 60 as a dietary supplement?
Here is my attempt to provide a brief summary:
The endogenous production of reactive oxygen species (ROS) is a consequence of basal cellular respiration. At a moderate level, ROS are involved in cell signalling and required for biochemical energetics of life. When ROS overwhelm the cellular anti-oxidant defence system, oxidative stress can cause damage to cellular proteins, lipids and nucleic acids. Oxidative stress has been implicated in the pathogenesis of atherosclerosis, neurodegeneration, cancer and musculoskeletal conditions. Therefore, it might be of therapeutic value to relieve the oxidative stress by neutralising ROS with extrinsic anti-oxidants. One potentially potent anti-oxidants is ‘carbon 60’ (also called Fullerene 60).
But what exactly is carbon 60?
Carbon 60 is a molecule composed of 60 carbon atoms arranged in a sphere, and is also known as a buckyball, a cluster of sixty carbon atoms in the shape of a ball, also known as buckminsterfullerene. The carbon atoms in C60 fullerene are linked to three adjacent carbon atoms by strong covalent bonds, and form a spherical pattern of 20 hexagons and 12 pentagons, also known as a truncated icosahedron. The C60 molecule is around 0.7 to 1 nanometres in diameter. Most carbon 60 is manufactured in the laboratory, using an electric arc between two carbon electrodes to create a soot from which the carbon 60 fullerene molecules can be extracted. Tweaking the soot-creating conditions also allows carbon nanotubes to be created instead of C60 buckyballs.
The medicinal properties of carbon 60 currently are the subject of much hype. One website lists 12 amazing health benefits of carbon 60.
#1 May Increase Longevity
#2 Scavenges Free Radicals
#3 May Promote Less Bodily Stiffness and Happier Joints
#4 Seems to Improve Immune Function
#5 Possibly Supports Brain Health
#7 Promotes Cleanliness & Supports Good Hygiene
#8 Might Help You Maintain an Even Waistline
#9 Might Be Useful As A Chemo Support Supplement
#10 Possible UV Protection
#11 Might Enhance Your Skincare Routine
#12 Could Prove Helpful As A Support for Male Infertility Treatments
Is there any evidence to justify these claims? My ‘rough and ready’ searches found just two clinical trials:
Highly purified and organic solvent-free fullerene-C60 was dissolved, at nearly saturated concentration of 278 ppm, in squalane prepared from olive oil, which is designated as LipoFullerene (LF-SQ) and was examined for usage as a cosmetic ingredient with antioxidant ability. The aim of this study was to assess the anti-wrinkle formation efficacy of LF-SQ in subjects. A total of 23 Japanese women (group I: age 38.9 +/- 3.8, n = 11, group II; age 39.4 +/- 4.3, n = 12) were enrolled in an 8-week trial of LF-SQ blended cream in a randomized, matched pair double-blind study. The LF-SQ cream was applied twice daily on the right or left half of the face, and squalane blended cream (without fullerene-C60) was applied as the placebo on another half of the face. As clinical evaluations of wrinkle grades, visual observation and photographs, and silicone replicas of both crow’s feet areas were taken at baseline (0 week) and at 4th and 8th weeks. Skin replicas were analyzed using an optical profilometry technique. The wrinkle and skin-surface roughness features were calculated and statistically analyzed. Subsequently, trans-epidermal water loss (TEWL), moisture levels of the stratum corneum, and visco-elasticity (suppleness: RO and elasticity: R7) were measured on cheeks by instrumental analysis. LF-SQ cream enhanced the skin moisture and the anti-wrinkle formation. LF-SQ cream that was applied on a face twice daily was not effective at 4th week, but significantly more effective than the placebo at 8th week (p < 0.05) without severe side effects. The roughness-area ratio showed significant improvement (p < 0.05) at 8th week with LF-SQ cream as compared to 0 week with LF-SQ cream, but no significant difference was detected between LF-SQ cream and the placebo. We suggest that LF-SQ could be used as an active ingredient for wrinkle-care cosmetics.
Oxidative stress plays a major role in acne formation, suggesting that oxygen radical scavengers are potential therapeutic agents. Fullerene is a spherical carbon molecule with strong radical sponge activity; therefore, we studied the effectiveness of fullerene gel in treating acne vulgaris. We performed an open trial using a fullerene gel twice a day; at 4 and 8 weeks, the mean number of inflammatory lesions (erythematous papules and pustules) significantly (P < 0.05) decreased from 16.09 ± 9.08 to 12.36 ± 7.03 (reduction rate 23.2%) and 10.0 ± 5.62 (reduction rate 37.8%), respectively. The number of pustules, consisting of accumulation of neutrophils, was significantly (P < 0.05) decreased from 1.45 ± 1.13 to 0.18 ± 0.60 (reduction rate 87.6%), and further in vitro assays of sebum production in hamster sebocytes revealed that 75 μM polyvinylpyrrolidone-fullerene inhibits sebum production, suggesting that fullerene suppresses acne through decreasing neutrophil infiltration and sebum production. After treatment for 8 weeks, the water content of the skin significantly (P < 0.05) increased from 51.7 ± 7.9 to 60.4 ± 10.3 instrumental units. Therefore, the fullerene gel may help in controlling acne vulgaris with skin care benefit.
So, would you buy a supplement of carbon 60? There are many products to chose from. Yet, many readers of this blog might hesitate: not only is the evidence hardly anything to write home about, but also the price tags are eye-watering (~£40/100ml of oil enriched with carbon 60).
According to WebMed, the shark cartilage (tough elastic tissue that provides support, much as bone does) used for medicine comes primarily from sharks caught in the Pacific Ocean. Several types of extracts are made from shark cartilage including squalamine lactate, AE-941, and U-995.
Shark cartilage is most famously used for cancer. Shark cartilage is also used for osteoarthritis, plaque psoriasis, age-related vision loss, wound healing, damage to the retina of the eye due to diabetes, and inflammation of the intestine (enteritis).
A more realistic picture is pained by this abstract:
The promotion of crude shark cartilage extracts as a cure for cancer has contributed to at least two significant negative outcomes: a dramatic decline in shark populations and a diversion of patients from effective cancer treatments. An alleged lack of cancer in sharks constitutes a key justification for its use. Herein, both malignant and benign neoplasms of sharks and their relatives are described, including previously unreported cases from the Registry of Tumors in Lower Animals, and two sharks with two cancers each. Additional justifications for using shark cartilage are illogical extensions of the finding of antiangiogenic and anti-invasive substances in cartilage. Scientific evidence to date supports neither the efficacy of crude cartilage extracts nor the ability of effective components to reach and eradicate cancer cells. The fact that people think shark cartilage consumption can cure cancer illustrates the serious potential impacts of pseudoscience. Although components of shark cartilage may work as a cancer retardant, crude extracts are ineffective. Efficiencies of technology (e.g., fish harvesting), the power of mass media to reach the lay public, and the susceptibility of the public to pseudoscience amplifies the negative impacts of shark cartilage use. To facilitate the use of reason as the basis of public and private decision-making, the evidence-based mechanisms of evaluation used daily by the scientific community should be added to the training of media and governmental professionals. Increased use of logical, collaborative discussion will be necessary to ensure a sustainable future for man and the biosphere.
To be clear: there is no good evidence that the supplements commercially available currently are effective for any condition.
Now, there is more news on this topic:
The objective of this study was to analyse labelling practices and compliance with regulatory standards for shark cartilage supplements sold in the United States. The product labels of 29 commercial shark cartilage supplements were assessed for compliance with U.S. regulations. Claims, including nutrient content, prohibited disease, and nutritional support statements, were examined for compliance and substantiation.
Overall, 48% of the samples had at least one instance of non-compliance with labelling regulations. The most common labelling violations observed were:
- missing a domestic address/phone number,
- non-compliant nutrient content claim,
- missing/incomplete disclaimer,
- missing statement of identity,
- prohibited disease claims,
- incomplete “Supplement Facts” label.
The use of prohibited disease claims and nutritional support statements without the required disclaimer is concerning from a public health standpoint because consumers may delay seeking professional treatment for a disease.
The authors concluded that the results of this study indicate a need for improved labelling compliance among shark cartilage supplements.
In summary, it seems that shark cartilage supplements are bad for all concerned:
- Patients who rely on them might hasten their death.
- Sharks are becoming an endangered species.
- Consumers are being mislead and misinformed.
There is just one party smiling: the supplement manufacturers who make a healthy profit destroying the health of gullible consumers and patients.
Carl Sagan was a giant in critical thinking and has inspired many, including myself. His book THE DEMON HAUTED WORLD is a classic. In it, he published his ‘BALONEY DETECTION KIT’. As it relates to SCAM and so much more that troubles us today, I today take the liberty of citing it here.
- Wherever possible there must be independent confirmation of the “facts.”
- Encourage substantive debate on the evidence by knowledgeable proponents of all points of view.
- Arguments from authority carry little weight — “authorities” have made mistakes in the past. They will do so again in the future. Perhaps a better way to say it is that in science there are no authorities; at most, there are experts.
- Spin more than one hypothesis. If there’s something to be explained, think of all the different ways in which it could be explained. Then think of tests by which you might systematically disprove each of the alternatives. What survives, the hypothesis that resists disproof in this Darwinian selection among “multiple working hypotheses,” has a much better chance of being the right answer than if you had simply run with the first idea that caught your fancy.
- Try not to get overly attached to a hypothesis just because it’s yours. It’s only a way station in the pursuit of knowledge. Ask yourself why you like the idea. Compare it fairly with the alternatives. See if you can find reasons for rejecting it. If you don’t, others will.
- Quantify. If whatever it is you’re explaining has some measure, some numerical quantity attached to it, you’ll be much better able to discriminate among competing hypotheses. What is vague and qualitative is open to many explanations. Of course there are truths to be sought in the many qualitative issues we are obliged to confront, but finding them is more challenging.
- If there’s a chain of argument, every link in the chain must work (including the premise) — not just most of them.
- Occam’s Razor. This convenient rule-of-thumb urges us when faced with two hypotheses that explain the data equally well to choose the simpler.
- Always ask whether the hypothesis can be, at least in principle, falsified. Propositions that are untestable, unfalsifiable are not worth much. Consider the grand idea that our Universe and everything in it is just an elementary particle — an electron, say — in a much bigger Cosmos. But if we can never acquire information from outside our Universe, is not the idea incapable of disproof? You must be able to check assertions out. Inveterate skeptics must be given the chance to follow your reasoning, to duplicate your experiments and see if they get the same result.
As I said, this is a good book; I warmly recommend it to you.
