Allopathic meicine and allopathy (from Greek ἄλλος, állos, other, different + πάϑος, páthos, suffering) are terms coined by Samuel Hahnemann, the founder of homeopathy. Originally intended as a characterization of standard medicine in the early 19th century, these terms were rejected by mainstream physicians and quickly acquired negative undertones. In the United States the term "allopathic" has been used in contexts not related to homeopathy, but it has never been accepted by the medical establishment, and is not a label that such individuals apply to themselves.
