placebo effect, n.
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.
"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."
