        Ⅵ.  What's Milk Thislte

Milk thistle is native to Europe and was introduced into North America by early colonists. Milk thistle is found throughout the eastern United States, California, South America, Africa, Australia, and Asia.

Milk thistle (Silybum marianum) has been used since Greco-Roman times as an herbal remedy for a variety of ailments, particularly liver problems. In the late 19th and early 20th centuries physicians in the United States used milk thistle seeds to relieve congestion of the liver, spleen, and kidneys. Today, several scientific studies suggest that active substances in milk thistle (particularly silymarin) protect the liver from damage caused by viruses, toxins, alcohol, and certain drugs such as acetaminophen (a common over the counter medication used for headaches and pain; acetaminophen, also called paracetamol, can cause liver damage if taken in large quantities or by people who drink alcohol regularly).


Many professional herbalists recommend milk thistle extract for the prevention and/or treatment of various liver disorders including viral hepatitis, fatty liver associated with long term alcohol use, and liver damage from drugs and industrial toxins such as carbon tetrachloride.

Historically, people have used milk thistle for liver disorders and gallbladder problems

Milk thistle is promoted as a dietary supplement for hepatitis, cirrhosis, jaundice, diabetes, indigestion, and other conditions.



        Ⅶ.  Benefits of Milk Thistle Extract 

1.  Milk thistle Extract is used for varicose veins, menstrual difficulty, and congestion in the liver, spleen and kidneys.


2.  Milk thistle Extract has also been taken to increase breast-milk production, stimulate the secretion of bile, and as a treatment for           depression.


3.  Milk thistle Extract nutritionally supports the liver's ability to maintain normal liver function. It has shown positive effects in treating       nearly every known form of liver disease, including cirrhosis, hepatitis, necroses, and liver damage due to drug and alcohol abuse.


4.  Preliminary laboratory studies also suggest that active substances in milk thistle extract may have anti-cancer effects. One active             substance known as silymarin has strong antioxidant properties and has been shown to inhibit the growth of human prostate,                 breast, and cervical cancer cells in test tubes.

        Ⅷ.  What are the side effects of taking Milk Thistle extract


Taken in appropriate doses, oral use of milk thistle appears to be safe.

Milk thistle can cause:

  • Gastrointestinal issues, such as diarrhea, constipation, nausea, vomiting and abdominal bloating

  • Itchiness

  • Headache

If you have diabetes, use milk thistle with caution, since the supplement might lower blood sugar. There is also concern that milk thistle might affect estrogen levels. If you have breast cancer, uterine cancer, ovarian cancer, endometriosis or uterine fibroids, consider avoiding milk thistle.

Milk thistle can cause an allergic reaction, including a severe, potentially life-threatening allergic reaction (anaphylaxis). An allergic reaction is more common in people who are allergic to other plants in the Asteraceae family, such as ragweed, daisies, marigolds and chrysanthemums.
