Eclectic medicine- 

This is mentioned only for historical purposes as this was a medical system in the US existing from 1820-1939 when the last eclectic medical school closed.  Eclectic medicine had its roots in early American herbal medicine and was an extension of Thomsonian medicine and Native American medicine.  At the time of its initiation in the 1820s, standard medical practices at the time extensively used cathartic purges using calomel and other mercury based remedies as well as extensive bloodletting- practices common in Europe.  Eclectic medicine was a reaction to those practices that they considered barbaric and also Eclectic medicine was an attempt to restrict Thomsonian medical innovations (herbal medicine) to medical professionals.  Eclectic medicine had numerous medical schools with one of the earliest being the Reformed Medical College of New York in 1837.  In 1833, the Eclectic Medical Institute in Worthington, Ohio graduated its first class in 1833, then the school moved to Cincinnati in 1842. Training in these institutions were in physiology and conventional medicine along with herbal and botanical medicine. By the 1850s, the influence of the dozen medical schools of eclectic medicine was becoming widespread and standard medical doctors began using herbal salves of Eclectic medicine.  Eclectic medicine was in competition with other forms of medicine that were on equal footing in the 1800s and early 1900s including homeopathy (there were many homeopathic hospitals at one time), native American medicine, chiropractic, osteopathy, and standard medicine.
