Homeopathy / Faith healing
Weekend read: On occasional weekends, I’ll post old columns and articles that still seem relevant. Let me know what you think, please.
For the half billion people worldwide who use homeopathic remedies, the potions can be as healing as a hug, as benignly nutty as knocking wood for luck, or as dangerous as believing a dashboard Jesus will protect you from an onrushing train. What homeopathy is not, however, is medicine that is scientifically proven to work better than a placebo. Independent researchers have debunked almost every favorable study they have examined, and a $1 million prize for proving homeopathy’s efficacy remains unclaimed.
Some homeopaths counter that their cures are not amenable to scientific proof. That’s fine, if you want to call the multi-billion dollar industry what it is: faith healing.
The global homeopathic market, $6.2 billion in 2020, is projected to rake in almost $20 billion by 2030.
The U.S. homeopathic industry would have made my cousin proud. As a kid, he bottled his bath water and sold it to his schoolmates as a magic potion. Unlike this enterprising little charlatan (who went on to work for the Nixon administration – you can’t make this stuff up), most homeopaths claiming imaginary powers for ordinary water actually believe in their products. Some are licensed physicians, others simply hang up a shingle. But consciously fraudulent or not, the homeopathy industry is marketing magic; selling placebos wrapped in ritual, tied with a bright bow of superstition.
Homeopathy rests on three unproven tenets:
First, “Like treats like.” Because arsenic causes shortness of breath, for example, homeopaths prescribe its “spirit” to treat diseases such as asthma.
Second, the arsenic or other active ingredient is diluted in water and then that dilution is diluted again and so on, dozens of times, guaranteeing – for better and worse – that even if the dose has no therapeutic value, it does no harm.
Third, the potion is shaken vigorously so that it retains a “memory” of the allegedly curative ingredient, a spirit-like essence that revives the body’s “vital force.”
“A shocking fact,” writes homeopathic practitioner Bill Gray, “is that the more the remedy is shaken and diluted (serially), the more powerful the curative action! This remains true even beyond the point of there being even one molecule left in the solution!”
Scientific evidence for the memory? None. Rigorous, replicable, double-blind studies documenting cure rates higher than placebo? Few to none.
So what about the fact that some homeopathic patients get better? Part of the effect comes from the ritual of consultation with a practitioner who treats the patient like a person rather than a body part on an assembly line. And just taking anything can help; the placebo effect is real. In gold-standard, double-blind studies, placebos presented as possible cures sometimes rival pharmaceuticals for effectiveness, or beat taking nothing at all.
Nor are the effects simply psychological. When volunteers took a placebo that they were told contained painkillers, they experienced relief, while researchers watching PET scans of the subjects’ brains tracked increased levels of the body’s own pain-relieving endorphins. In other studies, research subjects given placebos instead of antidepressants also showed chemical changes in their brains. FDA data for six top antidepressants showed that 80 percent of their effect was duplicated in placebo control groups.
Which brings us to the patient’s dilemma:
Have faith in 19th century magic or rely on a pharmaceutical industry that suppresses negative outcomes (including death), promotes drugs for nonexistent diseases, repackages old drugs in new bottles to circumvent patent expirations, bribes doctors with perks and cash and hires ghost writers to author favorable studies? Given the hype, toxicity, and expense of many drugs and Big Pharma’s snake-oil tactics, the side effects of water (laced with “memory”) start looking pretty damn good. If your condition is relatively minor, self-limiting, or untreatable, you may be a lot better off drinking homeopathy’s Kool-Aid-less Kool-Aid.
But if you have strep, a broken bone or a tumor, or if you need immunization from infectious disease, reliance on a homeopathic placebo may kill you.
British newspapers recently reported that homeopathic clinics and pharmacies offered unproven products to prevent malaria and other diseases including typhoid, dengue fever and yellow fever. Travelers who thought they were protected ignored warnings to use mosquito netting; some contracted malaria. And during the height of the smallpox-terror scare in 2003, U.S. doctor Bill Gray tried to market a homeopathic “shield” for smallpox. One reason the FDA stopped him was that its “Homeopathic Pharmacopoeia” does not recognize the “shield’s” supposed ingredient – Variolinum, purportedly extracted from “a ripened pustule of small pox.” It bothers the witless FDA not a whit that Gray’s water actually contained no Variolinium.
In general, the FDA turns a blind eye to homeopathy’s dangers and nonsense. Homeopathic remedies “are the only category of spurious products legally marketable as drugs,” according to Stephen Barrett, M.D., and Varro E. Tyler, Ph.D., authors of The Honest Herbal. “If the FDA required homeopathic remedies to be proven effective in order to remain marketable – the standard it applies to other categories of drugs – homeopathy would face extinction in the United States. ” —2002, In These Times
Update: April 28, 2023. As you might expect, quacks, true believers, and celebrity huckster-ranters including Joe Rogan touted a panoply of homeopathic preventions and treatments for Covid-19 and long Covid. And as you should expect, they proved worthless. In fact, worse than useless, since many people, like football player Aaron Rodgers, who took homeopathics instead of getting vaccinated ended up infected by the virus and likely infecting others.
It saddens (OK, irritates the hell out of) me that my local coop sells these useless —except to enrich the manufacturers—bottles of water
As a scientist I fully agree with your article. Homeopathy fits in with the anti-science trend in our culture. "If the science supports what you want to believe, it must be true. If it is contrary, then it must be false. Actually is this any different from religion?
I also agree that at least some pharmaceutical companies put greed way ahead of any duty to public health. Drugs that can save one's life have enormously inflated prices, even when developed through publicly funded research. As bandits say when pointing a pistol up your nose, "Your money or your life!"
Enjoyed the read, your brother wrote an interesting reply.
