Jerome Groopman in the Wall Street Journal: Some 60 million Americans use supplements, megavitamins, herbs and other so-called "alternative" treatments...But we are now learning what happens when the testimonials are subjected to objective testing. In February, the results of a large clinical trial of the supplements glucosamine and chondroitin sulfate for osteoarthritis were released. These data came on the heels of a rigorous assessment of the herb saw palmetto for symptoms of an enlarged prostate gland. Both studies failed to show clinical efficacy. All this should mark a sea change in how the public views such treatments.
Yeah, it should, but I bet it won't happen quickly. The backlash against science in this country is strong, it's well-funded and has deep ideological taproots. Groopman's rational conclusion may not apply.
