Placebo therapy

From DrugPedia: A Wikipedia for Drug discovery

Placebo is an inactive substance or treatment that looks the same as, and is given the same way as, an active drug or treatment being tested. The effects of the active drug or treatment are compared to the effects of the placebo.

Placebo therapy can be defined as an inactive treatment or procedure that is intended to mimic as closely as possible a therapy in a clinical trial. Also called sham therapy.
