Placebo definition

Placebo definition

Placebo - an inert substance that has no biological, chemical, or other action within the body, taken with the intent of producing a therapeutic effect. The placebo effect refers to the sense of improvement of symptoms an individual may experience when taking or using a product that has no active ingredients. Researchers often use placebo products when testing new drugs, particularly medications such as PAIN relievers (ANALGESIC MEDICATIONS), in which the assessment of effectiveness has a subjective component.
