A placebo is a substance or treatment with no active therapeutic effect. It is often used in clinical trials as a control group to compare the effectiveness of a new medication or treatment. In some cases, a placebo can still lead to a reduction in pain or other symptoms due to the placebo effect, which is the psychological and physiological response of the body to the belief that a treatment is effective.
