Eclectic medicine
The term was coined by Constantine Samuel Rafinesque (1784–1841), a botanist and Transylvania University professor who had studied Native American use of medicinal plants, wrote and lectured extensively on herbal medicine, and advised patients and sold remedies by mail. Rafinesque used the word "eclectic" to refer to those physicians who employed whatever was found to be beneficial to their patients (eclectic being derived from the Greek word "eklego", meaning "to choose from").
