Allopathic medicine refers to the practice of conventional medicine that uses pharmacologically active agents or physical interventions to treat or suppress symptoms or pathophysiologic processes of diseases or conditions. It was coined by Samuel Hahnemann (1755–1843), a homeopath, in 1810. Although "allopathic medicine" was rejected as a term by mainstream physicians, it was adopted by alternative medicine advocates to refer pejoratively to conventional medicine.
