Just when I thought I was out, they pull me back in. My blogging plan was to take a break from my series of naturopathy versus science posts, where I’ve been contrasting the advice from naturopaths against the scientific evidence. From a blogging perspective, naturopathy is a fascinating subject to scrutinize as there is seemingly no end of conditions for which naturopaths offer advice that is at odds with the scientific evidence. From a health care perspective, however, reading the advice of naturopaths is troubling. Naturopaths promote themselves as health professionals capable of providing primary care, just like medical doctors. And they’re increasingly seeking (and obtaining) physician-like privileges from governments. Naturopathy seems to be getting an easy ride from regulators, despite a lack of evidence that shows naturopathy offers anything distinctly useful or incrementally superior to science-based medicine.
Defining the scope of “naturopathic” treatment is difficult. Naturopaths offer an array of disparate health practices like homeopathy, acupuncture and herbalism that are only linked by the (now discarded) belief in vitalism – the idea we have a “life force”. From this philosophy can sometimes emerge reasonable health advice, but that has little to do with the science or the evidence. As long as it’s congruent with the naturopathic belief system, it’s acceptably “naturopathic”. In past posts I’ve looked at the naturopathic perspectives on fake diseases, infertility, prenatal vitamins, vaccinations, allergies and even scientific facts themselves. An advertisement passed to me this week promoted a naturopath who claims to treat pediatric conditions like ADHD and learning disabilities: (more…)
Who would you guess authored a 250-page report which begins with this Preface?
This report marks the culmination of an intensive four-year review of quackery and its impact on the elderly. . . As this report details, quackery has traveled far from the day of the pitchman and covered wagon to emerge as big business. Those who orchestrate and profit from the sale and promotion of these useless and often harmful “health” products are no longer quaint and comical figures. They are well organized, sophisticated and persistent. [We estimate] the cost of quackery – the promotion and sale of useless remedies promising relief from chronic and critical health conditions – exceeds $10 billion a year. The costs of quackery in human terms, measured in disillusion, pain, relief forsaken or postponed because of reliance on unproven methods, is more difficult to measure, but nonetheless real. All too frequently, the purchaser has paid with his life. While the impact of quackery on our lives has been increasing and growing in sophistication, public and private efforts designed to address and control this problem have diminished, been redirected or disbanded.
News this week that a randomized controlled trial of green coffee bean (GCB) has been officially retracted from the medical literature signals what is hopefully the end to one of the most questionable diet products to appear on the market in years. Plucked from obscurity and then subjected to bogus research, it’s now clear that the only people that actually benefited from GCB were those that profited from its sale. GCB had some powerful boosters, too. Once it became one of Dr. Oz’s “miracle” weight loss cures, sales exploded following two hype-filled episodes. Oz even did a made-for TV clinical trial with GCB, ignoring the requirements for researchers to obtain ethical approvals before conducting human subject research. Oz’s promotion of GCB was so breathless and detached from the actual evidence that his actions were subsequently eviscerated by Senator Clair McCaskill during televised hearings on weight loss scams. It’s a long, sordid, ugly and yet entirely predictable story. (more…)
Naturopathy has been legal in Connecticut for almost 90 years, but with a scope of practice limited to counseling and a few treatments like physiotherapy, colonic hydrotherapy and “natural substances.” There was no specific authority to diagnose and treat. All of that changed on October 1, 2014, courtesy of the Connecticut legislature, which, in the words of the American Association of Naturopathic Physicians (AANP), “modernized” the naturopathic scope of practice.
Actually, the legislature did nothing of the sort. Naturopathy is based on the prescientific concept of vitalism, and we find it right there in the very first paragraph of the new law. Naturopathy is defined as:
diagnosis, prevention and treatment of disease and health optimization by stimulation and support of the body’s natural healing processes, as approved by the State Board of Natureopathic [sic] Examiners, with the consent of the Commissioner of Public Health. . .
Also included in the expanded scope of practice are:
ordering diagnostic tests and other diagnostic procedures, . . . ordering medical devices, including continuous glucose monitors, glucose meters, glucose test strips, barrier contraceptives and durable medical equipment; and . . . removing ear wax, removing foreign bodies from the ear, nose and skin, shaving corns and calluses, spirometry, tuberculosis testing, vaccine administration, venipuncture for blood testing and minor wound repair, including suturing.
Yahoo News appears to have confused NaturalNews with actual news. It’s not. NaturalNews is the in-house propaganda organ for Mike Adams, whom I’ll introduce in a minute (although he needs no introduction for most readers here). A couple of recent examples:
A recycled story, over a year old, from NaturalNews, appearing on Yahoo News last week. It starts out as a fairly straightforward report of the Japanese’s governments suspending its recommendation if favor of the HPV vaccine pending further research, although government health officials were still standing by the vaccine’s safety. Actually, Medscape reported that the actual rate was 12.8 serious adverse side effects reported per 1 million doses, a fact not revealed in the NaturalNews story. These effects were correlated with the vaccine; there is no evidence of causation.
After this rather tame start, NaturalNews cranks it up to 11 and beyond, as David Gorski would say. Governments which still recommend HPV vaccinations “remain under the thumb of Merck’s vaccinations spell” even though Merck is “an organization of murderers and thieves.” A scary list of adverse events are described as “side effects of Guardasil” even though causation has not been shown.
Two days ago there was an “ongoing debate”? There is no ongoing debate about “whether or not vaccines cause autism” because there never was any credible evidence that vaccines cause autism and there still isn’t.
Typical example of a Vitamin K supplement.
Science is complicated. Simple concepts that appear at first to be obviously true or untrue usually turn out to be more nuanced than we thought. Newtonian physics was taken as “the truth” until we learned in the 20th century that it didn’t apply on cosmological or subatomic scales. Medicine and human physiology are more complicated than most people realize or want to believe. A case in point is the recent realization that vitamin K is not a single chemical compound, but a whole family of them, and that vitamin K2 has unique properties that vitamin K1 lacks.
Recently, there has been some interesting preclinical research on K2 that warrants further study to tease out its implications for human health, diet, and supplementation. There has also been a lot of hype that warrants taking its claims not with a grain but with a large bolus of salt. According to Canadian naturopath Kate Rhéaume-Bleue, author of Vitamin K2 and the Calcium Paradox:
- It could save your life
- It is missing from the modern diet
- It is the most important anti-aging nutrient for fighting wrinkles, Alzheimer’s, heart disease, osteoporosis and more
- It promotes straight, cavity-free teeth
- It is needed to get the benefits from calcium and vitamin D supplements; without it, those nutrients will increase the risk of heart attack and stroke
- It is the only vitamin known to prevent and reverse atherosclerosis
The old adage is still true: if something sounds too good to be true, it probably is. There is only weak evidence behind these strong claims. (more…)
About a month ago, I finally wrote the post I had been promising to write for months before about medical marijuana. At the time, I also promised that there would be follow-up posts. Like Dug the Dog seeing a squirrel, I kept running into other topics that kept me from revisiting the topic. However, over the past couple of weeks, the New York Times gave me just the little nudge I needed to come back and revisit the topic, first by openly advocating the legalization of marijuana, then by vastly overstating the potential medical benefits of pot (compare the NYT coverage with my post from a month ago), and finally this weekend by running a story lamenting the federal law that makes research into medical marijuana difficult in this country.
I stated my position on marijuana last time, which is that marijuana should be at least decriminalized or, preferably, legalized, taxed, and regulated, just like tobacco and alcohol. I also likened the cult of medical marijuana to the “new herbalism,” because it (1) vastly inflates the potential of medicinal uses of marijuana and (2) ascribes near-mystical powers to smoking or making extracts out of marijuana, rather than identifying and isolating constituents of the plant that might have medicinal value. All of this is very much like herbalism in alternative medicine. Indeed, promoting laws legalizing medicinal marijuana is such an obvious ploy to open the door to full legalization that some advocates don’t even bother to disingenuously deny it any more. Given that I tend to support legalization, as a physician this sort of deception irritates me. It also has consequences, particularly when overblown claims are made for what cannabis can do. Perhaps the best example of this is the claim that cannabis cures cancer, which pops up all over the Internet in memes such as the one in the image above.
Ladies, how would you like a chiropractor to deliver your baby? How about perform your annual well-woman exams, such as breast exam, bi-manual pelvic exam, speculum exam, recto-vaginal exam and Pap smear?
Sound out of their league? I thought so too. Way out. But, in some parts of the U.S., the law allows chiropractors to do all of these things and a great deal more. Including “adjusting” your basset hound.
A 2011 survey asked chiropractic regulatory officials whether their jurisdictions (all states, plus D.C., Virgin Islands and Puerto Rico, but I’ll refer to them collectively as the “states”) allowed 97 different diagnostic, evaluation, and management procedures. The results were recently reported and interpreted in the Journal of Manipulative and Physiological Therapeutics, in an article authored by Mabel Chang, DC, MPH, who was primarily responsible for the survey. Missouri allows the most procedures (92) and Texas, the fewest (30). A handful of states did not respond or did not respond to all questions, but the overall response rate was 96%. Results from a survey of Canada, Australia and New Zealand will be reported in a separate article. (more…)
In May, prompted by an uncritical article in the Daily Mail, the internet was buzzing about a company that was offering drinkable sunscreen. This is one of those game-changer health products that immediately garners a great deal of attention.
At first the claim seems extraordinary, but it is not impossible. It is theoretically possible to drink a substance that becomes deposited in the skin and absorbs or reflects UV radiation providing protection. However, upon reading the details it becomes immediately apparent that the product in question is pure snake oil.
The product is Harmonized Water by Osmosis Skin Care. In fact, UV protection is just one claim among many for the harmonized water line of products. The website claims:
- Remarkable technology that imprints frequencies (as standing waves) onto water molecules.
- Advances in the ability to “stack” thousands of frequencies onto one molecule.
- Revolutionary formula allows us to reverse engineer the frequencies of substances found in nature and/or the human body.
- Newly identified frequencies that have beneficial effects on the body.
A while ago, I wrote about how the Cleveland Clinic had recently opened a clinic that dispensed herbal medicine according to traditional Chinese medicine (TCM) practice. As regular readers of the SBM blog might expect, I was not particularly impressed or approving of this particular bit of infiltration of quackademic medicine into a major academic medical center, particularly given some of the amazingly pseudoscientific treatments espoused by the naturopath who was running the clinic. I also pointed out that, although herbalism is the most plausible (or perhaps I should say the least implausible) of modalities commonly associated with “complementary and alternative medicine” (CAM) or “integrative medicine”, it still exhibits a number of problems, the biggest of which is what I like to call either the delivery problem or the bioavailability problem. In brief, herbs, when they work, are adulterated drugs. The active ingredient is usually a minor constituent, embedded in thousands of other constituents that make up herbs, and it’s almost impossible to control lot-to-lot consistency with respect to content or active ingredients given how location, weather, soil conditions, rainfall, and many other factors can affect how the plants from which the medicines are extracted grow and therefore their chemical composition. To demonstrate the concept, I pointed out that it’s much safer and more predictable to administer digoxin to a patient who needs its activity on the heart than it would be for the patient to chew on some foxglove leaves, given that the therapeutic window (the difference between the doses needed to produce therapeutic effects and the lowest dose that will cause significant toxicity) is narrow.
Which brings me to medical marijuana, a.k.a. medical cannabis.
