Thousands of years of traditional usage has been verified by science for the uses of Milk Thistle as a medicinal herb. Mainly used to reverse the effects of various poisons and act as remedy for depression. Some trials have been performed on chemotherapy patients that suggests it supports healthy liver function and works synergistically with other chemotherapy drugs. Further research suggests silybin, a compound found in milk thistle has strong anti cancer properties. Any time the liver is under stress (especially from chronic alcoholism) this herb can be used. In the modern western world, it is used primarily for alcohol with-drawls.
