Milk thistle ( Silybum marianum ) has been used since Greco-Roman times as an herbal remedy for a variety of ailments, particularly liver problems. In the late 19th and early 20th centuries physicians in the United States used milk thistle seeds to relieve congestion of the liver, spleen, and kidneys. Today, several scientific studies suggest that active substances in milk thistle (particularly silymarin) protect the liver from damage caused by viruses, toxins, alcohol, and certain drugs such as acetaminophen (a common over the counter medication used for headaches and pain; acetaminophen, also called paracetamol, can cause liver damage if taken in large quantities or by people who drink alcohol regularly.)

Many professional herbalists recommend milk thistle extract for the prevention and/or treatment of various liver disorders including viral hepatitis, fatty liver associated with long term alcohol use, and liver damage from drugs and industrial toxins such as carbon tetrachloride.

Cancer - Preliminary laboratory studies also suggest that active substances in milk thistle may have anti-cancer effects. One active substance known as silymarin has strong antioxidant properties and has been shown to inhibit the growth of human prostate, breast, and cervical cancer cells in test tubes. Further studies are needed to determine whether milk thistle is safe or effective for people with these forms of cancer.
