Milk Thistle has been used for hundreds of years to treat liver disease. Studies show that it protects the liver from alcohol-related damage by altering and stabilizing the structure of the liver cells so that toxins cannot enter them as easily. Silymarin, the main component of milk thistle seeds, helps reduce inflammation and promotes cell repair.

      According to the National Cancer Institute, laboratory studies demonstrate that silymarin, the active substance in milk thistle, “stabilizes cellular membranes, stimulates detoxification pathways, stimulates regeneration of liver tissue, inhibits the growth of certain cancer cell lines, exerts direct cytotoxic activity toward certain cancer cell lines, and possibly increases the efficacy of certain chemotherapy agents”
