Origin:
The term "placebo" originated in the 12th century. In the liturgy of the Roman Catholic Church, the "placebo" was a chant sung at the burial service when the coffin was lowered into the grave. The phrase "placebo Domino in regione vivorum" (I will please the Lord in the land of the living) was taken from Psalm 116 of the Bible.
Over time, the term "placebo" came to be used more generally to refer to a harmless substance or treatment that was given to someone in place of a real medicine. This was often done in order to appease the patient or to make them believe that they were receiving effective treatment.
In modern medicine, placebos are often used in clinical trials to evaluate the efficacy of new drugs. By comparing the effects of a placebo to the effects of the real drug, researchers can determine whether the drug is actually having any effect.
