Silymarin (Silybum marianum), also known as Milk Thistle, is an herb that is well-documented in early traditional herbal medicine. Studies abroad and in the U.S. have indicated that constituents in Silymarin may help to support healthy liver function.*

• Silymarin has antioxidant properties. Antioxidants are thought to prevent or lessen damage to body cells that is caused by a chemical process called oxidation.
• Anti-inflammatory effects of silymarin help keep liver cells from swelling in response to injury.
• Silymarin seems to encourage the liver to grow new cells, while discouraging the formation of inactive fibrous tissue.
• By changing the outside layer of liver cells, silymarin may also keep certain harmful chemicals from getting into liver cells.
• Milk thistle may also cause the immune system to be more active.
  
  

Silymarin and other chemicals from milk thistle have also been tested in laboratory studies involving various types of human cancer cells. In general, they seem to interrupt cancer cell division as well as shortening the time that cancer cells live. They may also stop or limit the formation of new blood vessels that supply tumors. Most research has centered on breast cancer and prostate cancer, but milk thistle is also being tested for treating other cancers such as leukemia. In some animal studies, certain types of breast cancer tumors actually increased in number and/or seriousness when milk thistle was given to female animals with existing breast tumors. However, the application of a second milk thistle chemical, silibinin, to the skin of laboratory animals has protected the animals against the development of skin cancer — either before or immediately after exposure to damaging radiation. Silibinin may even help to restore damaged skin somewhat by mending DNA that has been harmed by ultraviolet rays. In addition, some chemicals from milk thistle may increase the effectiveness of current anticancer drugs. Some of these anticancer effects are being studied in early-phase human trials, but none is confirmed, yet.

Milk thistle and chemicals derived from it are being studied for a number of additional possible effects. For example, in animal studies and one small study of humans, milk thistle produced modest reductions in cholesterol levels. Results of separate laboratory studies show that milk thistle may help to protect the heart muscle from damage caused by certain drugs. However, these potential uses have not been well-studied in humans nor have they been proved in animal or laboratories studies.
