Milk Thistle

Milk thistle is a plant whose seeds and the parts above the ground are used to make medicine. Milk thistle is widely used for liver disorders, such as liver damage that resulted from the consumption of chemicals, jaundice, mushroom poisoning, cirrhosis of the liver, chronic inflammatory liver disease, and chronic hepatitis. However, researchers haven't yet concluded that milk thistle is really effective for these uses.
Today, milk thistle is used for heartburn, loss of appetite, dyspepsia, and gallbladder complaints. It shows some effectiveness in the treatment of diabetes, diseases of the spleen, hangover, prostate cancer, depression, malaria, uterine complaints, allergy symptoms, increasing breast milk flow, and starting menstrual flow. Milk thistle seeds protect liver from drugs and toxic chemicals. These possess anti-inflammatory and antioxidant effects. Besides, milk thistle improves the estrogen effects.

Milk thistle is mainly safe for most grown-ups, however, it may cause a laxative effect. Some other side effects may include nausea, indigestion, diarrhea, intestinal gas, fullness, pain, bloating, and loss of appetite. It is not recommended to be taken by pregnant or breast-feeding women. Little information is known about the use of milk thistle in this period.
Milk thistle may cause allergic reactions in people sensitive to the plants known as Asteraceae/Compositae including chrysanthemums, ragweed, daisies, marigolds, and others. So, if you're allergic to any of these plants, consult your healthcare provider.
Hormone-sensitive diseases such as uterine cancer, breast cancer, endometriosis, ovarian cancer, or uterine fibroids are a reason to think twice before starting to take milk thistle. The matter is that extracts from this plant can act like estrogen. So, if you have any condition which can be worsened by estrogen, avoid these extracts. It has to be mentioned that milk thistle seed extracts do not act like estrogen.
