History: The Ancient Greek physician Dioscoides wrote that the bark of the White Willow tree has the ability to reduce fevers and pain. It was only discovered in modern times that the tree was rich in salicin, a natural pain reliever. In fact, the original recipe for aspirin called for the bark of the White Willow tree, although the modern aspirin is completely synthetic.
