Without a scientific understanding of  the basis of disease, there was nothing else to   turn to but blind trial and error with what we  could find in nature, that is if you discount   incantations and prayer, which were of course also  widely practiced. However, in the last 200 years   we have begun to understand precisely how things  like plant extracts exert their physiological   effects on the molecular level. You see, in  addition to the basic building blocks of life   we rely on in order to survive, plants produce  a huge variety of small molecules. The intended   purpose of these small molecules is certainly  not to help mankind alleviate disease. These   molecules are merely part of the chemical arsenal  a plant uses to defend itself from predators,   to compete for re
