Medical botany was the most significant social movement of the 1840s to express its opposition to the professionalization of medicine by defending the traditional right of everyman to be his own physician. It had close links to herbalism, and was popularised in Britain chiefly by Albert Isaiah Coffin, an American disciple of Thomson. His followers, the Coffinites, believed that all disease could be traced to obstructions in the flow of bodily heat. Hot vapour baths, and especially emetics brought the obstruction to the surface. He organised the Friendly Botanic Society of Great Britain, and local societies in several northern towns.
