I didn't know about this. It's not taught in medical school, at least not at mine. Really shocking stuff. We are taught to worship the "double blind placebo controlled study" as what separates "true" allopathic medicine from the complementary, alternative, naturalistic, etc.. The automatic answer when challenged by the effectiveness of a treatment which is not taught in allopathic medicine is: well, there's no double blind placebo controlled study that proves it's effective. The whole concept of placebo is that it should be nothing but a psychological effect.
Anything that is in the placebo MUST be in the actual drug for the whole "placebo-controlled" mantra to make sense.
To be honest, I'm not 100% convinced what is mentioned in that article is true. It's hard to believe. I'd have to see it in other sources before I buy it.
