Placebo

A placebo is a substance or treatment that resembles a real medical intervention but has no therapeutic effect. It can be an inactive substance, such as a sugar pill, or a procedure that mimics a real medical procedure without any actual biological effect.

Placebo Effect

The placebo effect refers to the phenomenon where a patient experiences a perceived improvement in their symptoms or overall health due to receiving a placebo. It is a psychological and physiological response that occurs when a person believes they are receiving a beneficial treatment, resulting in actual physiological changes in their body.

The placebo effect is often observed in clinical trials and medical research, where a control group is given a placebo instead of the actual medication being tested. The placebo group may still experience a positive therapeutic response, highlighting the powerful influence of expectations, beliefs, and psychological factors on health outcomes.
