Placebo effect
A placebo (/pləˈsiboʊ/ plə-see-boh; Latin placēbō, "I shall please"[2] from placeō, "I please")[3][4] is a simulated or otherwise medically ineffectual treatment for a disease or other medical condition intended to deceive the recipient. Sometimes patients given a placebo treatment will have a perceived or actual improvement in a medical condition, a phenomenon commonly called the placebo effect. Placebo effect consists of several different effects woven together, and the methods of placebo administration may be as important as the administration itself.[5]
