Many people believe that the placebo effect is solely a psychological phenomenon. But for some people, a placebo can have real, measurable therapeutic benefits. The power of the placebo effect is significant enough that it can actually skew study results. Additional research is needed to better understand how to leverage the placebo effect and when doing so might offer real benefits to patients.
