The placebo effect, first documented in the early 20th century, refers to the phenomenon where patients experience real improvements in their condition after receiving a treatment with no therapeutic value. The term "placebo," derived from Latin meaning "I shall please," was first used in the medical context in the 19th century. However, it was during World War II that the placebo effect gained significant attention. Dr. Henry Beecher, an anesthesiologist, observed that wounded soldiers reported pain relief after receiving saline injections, believing they were receiving morphine.

The placebo effect works primarily through the power of belief and expectation. When a patient believes that a treatment will work, their brain releases endorphins and other chemicals that can mimic the effects of actual medical treatments. Numerous studies have demonstrated the placebo effect across various conditions, including pain management, depression, and even Parkinson's disease. The effect highlights the mind's powerful influence on the body and underscores the importance of psychological factors in medical treatment.
