The origins of homeopathy are perhaps understandable. In the 18th Century medicine relied on basic methods such as bloodletting and complex concoctions. The treatment was as likely to make you worse or kill you, as it was to do anything else. Medicine at the time was clearly pre-scientific with the key aspect being the idea of balancing the four humors of the body, phlegm, blood, black bile, and yellow bile. Samuel Hahnemann, who rejected giving people bizarre brews, he proposed giving people a single substance with low doses.
