Placebos

A placebo is a vehicle for achieving a treatment effect by suggestion. It is an inactive substance (or therapy) that is given to a patient, knowing it will not have any direct therapeutic benefit.

Placebos are used in two situations:
1. A control intervention in controlled studies of drugs
2. For psychological benefit of the patient
