Milk thistle is a tall plant with large purple flowers native to Europe, and its main constituent is silymarin; it is promoted for liver disorders, diabetes, and other conditions. The page states there isn't enough high-quality evidence to allow definite conclusions about the effects of milk thistle on health conditions in people. Small studies suggest it may help control blood sugar in people with type 2 diabetes, though results are geographically limited, and for liver disease results from clinical trials have been conflicting or too limited to allow conclusions, with two NCCIH-funded studies showing no benefit from supplementation — per the NIH National Center for Complementary and Integrative Health; not medical advice.
There isn't enough high-quality evidence to reach definite conclusions about milk thistle; a small number of studies suggest it may help control blood sugar in type 2 diabetes, while trials for liver diseases have been conflicting or too limited to allow conclusions — per the U.S. National Center for Complementary and Integrative Health (NCCIH).
When taken orally, milk thistle appears to be well tolerated, with the most common side effects being digestive symptoms such as bloating, nausea, and gas; allergic reactions are possible in people allergic to related plants such as ragweed, chrysanthemum, marigold, and daisy. Some products may contain amounts of silymarin substantially different from what's stated on the label or be contaminated with pesticides, microorganisms, or mycotoxins — per the NIH National Center for Complementary and Integrative Health.
If you take any type of medicine, talk with your health care provider before using milk thistle or other herbal products, as some herbs and medicines interact in harmful ways. Little is known about whether it's safe to use milk thistle during pregnancy or while breastfeeding — per the NIH National Center for Complementary and Integrative Health.
