Their materia medica seems to have consisted offew articles ; these were certain plants, powerful in their Operation,and sometimes producing sudden and surprising effects upon thehuman body. These savages seem to have had better ideas ofthe medical virtues of plants, than some who have imagined thatvegetables, fit only for food, were the most proper for medi-cine ; and that combining a great number of the most com-mon plants, might be a remedy for almost every disease. Vege-tables called poisonous are capable of producing great and sud-den alterations in the human body: May not many of them befound, upon accurate and well-judged experiments, like somechymical poisons, to be the best medianes ? The Indians haddiscovered effectual antidotes against the venom of rattle-snakes,which must have been a discovery of great importance to them,and may, possibly, be reckoned among their greatest improve-ments in the knowledge of medicine. Mr. Catesby mentions afact, which he says was well attested, of an Indian's daubinghimself with the juice of the purple bindweed, a species of theconvolvulus, and then handling a rattle-snake with his nakedhands, without receiving any injury.
