Before we go off on a tangent about how placebo acts, remember that 38% got better using placebo; 80% got better with a homeopathic remedy.

What we usually see in conventional medicine is that placebo is as effective and often more effective as the actual drug. This is certainly the case with SSRIs, as a recent study comparing the effects of Prozac and Panax to placebo revealed (placebo acted more curatively in more people--plus no side effects).
