Milk thistle (Silybum marianum) is an herbal supplement and whose extracts have been recognized for centuries as "liver tonics" and are well-known to prevent or reverse hepatotoxicity of reactive drug metabolites or naturally occurring toxins. (Reference 1, 2) Silymarin, a mixture of flavanoid complexes, is the active component of Milk Thistle that protects liver and kidney cells from toxic effects of drugs, including chemotherapy. Although milk thistle has not significantly altered the course of chronic liver disease, it has reduced liver enzyme levels and demonstrated anti-inflammatory and T cell-modulating effects. There is strong preclinical evidence for silymarin's liver protective and anti-cancer effects, including inhibition of cancer cell growth in human prostate, skin, breast, and cervical cells. (Reference 1)

A number of studies have established the cancer chemopreventive role of silymarin in both in vivo and in vitro models. Silymarin modulates imbalance between cell survival and apoptosis through interference with the expressions of cell cycle regulators and proteins involved in apoptosis. In addition, silymarin also showed anti-inflammatory as well as anti-metastatic activity. Further, the protective effects of silymarin and its major active constituent, silibinin, studied in various tissues, suggest a clinical application in cancer patients as an adjunct to established therapies, to prevent or reduce chemotherapy as well as radiotherapy-induced toxicity. (Reference 3) In a study on the effects of pure flavonolignans from Milk Thistle on the antiproliferative end points in human prostate carcinoma cells, silymarin and silibinin were shown for the first time to suppress the activity of the DNA topoisomerase IIalpha gene promoter in DU145 cells. The findings suggest that extracts enriched for isosilybin B (a pure flavonolignan compound isolated from commercial silymarin extracts), or isosilybin B alone, might possess improved potency in prostate cancer prevention and treatment. (Reference 4)

Milk thistle is considered safe and well-tolerated, with gastrointestinal upset, a mild laxative effect, and rare allergic reaction being the only adverse events reported when taken within the recommended dose range. (Reference 1)
