English → English (gcide) Definition: Placebo effect Placebo effect \Pla*ce"bo ef*fect`\, n. (Med.) a reaction by a patient who receives a placebo[2], in which the symptoms of illness are lessened or an anticipated effect is experienced. Because the placebo[2] itself has no pharmacological activity, this reaction is mediated by the expectations of the patient receiving the placebo[2]; the reaction is considered as an example of the power of suggestion. Note: Dramatic subjective effects such as relief of discomfort or pain are sometimes observed due to administration of a placebo, but in some cases measurable physiological effects may also be observed.
