Usage notes
This term is used more rarely than the synonym. Some authors use only the term allopathetic, and treat it as a synonym of allopathic. Others, however, use both terms, employing allopathic to refer to conventional Western medicine, and reserving allopathetic to refer more specifically to the use of medications that produce the opposite effect of symptoms.
