Milk thistle is a medicinal plant, also known as Silybum marianum. According to MayoClinic.com, the seeds of milk thistle contain a favonoid complex called silymarin, which is commonly used in the United States and Europe to treat liver diseases. A milk thistle diet is one that promotes a healthy and well functioning liver. However, as with any new supplement, be sure to consult with your doctor before incorporating it into your diet.
Significance
You are likely exposed to many environmental pollutants on a regular basis. Chemicals are often present in the air, within consumer products and in processed foods, and the liver is responsible for filtering those toxins out of your bloodstream. In addition, liver disease has been on the rise in recent years. According to the American Liver Foundation, it is the seventh leading cause of death in the United States.
History
As MayoClinic.com explains, "Milk thistle has been used medicinally for over 2,000 years, most commonly for the treatment of liver and gallbladder disorders."
In her report, "Silibinin --- A Promising New Treatment for Cancer," published in "Anti-Cancer Agents in Medicinal Chemistry," Catherine Wing Ying Cheng explains that studying the biologically active principles contained within milk thistle's seed and fruit extracts began in the 1960s. Cheng and other scientists are now studying silymarin's antioxidant, anti-tumor and anti-inflammatory properties.
Types
Milk thistle is known by many other names, as well. According to MayoClinic.com, it is also called bull thistle, cardo blanco, Cardui mariae fructus, Chardon-Marie, emetic root, flavonolignans, Frauendistel, fruit de chardon Marie, heal thistle, holy thistle, isosilibinin, kanger, kocakavkas, kuub, lady's thistle, Mary thistle, mild thistle, milk ipecac, natursil, pig leaves, royal thistle, silidianin, snake milk, sow thistle, St. Mary's thistle, thisylin, Venus thistle, variegated thistle and wild artichoke.
Benefits
As MayoClinic.com explains, scientific evidence demonstrates that incorporating milk thistle in your diet can improve liver function for those suffering from cirrhosis and chronic liver disease. Plus, milk thistle may aid healing in many illnesses including acute viral hepatitis, Amanita phalloides mushroom poisoning, cancer, diabetes, indigestion, high cholesterol, liver damage from drugs or toxins and menopausal symptoms. However, there is not yet sufficient research to support these claims.
Warning
Like any dietary change, be sure to consult with your doctor before taking milk thistle. People who are allergic to daisies, artichokes, kiwi or any plants in the aster family may have a negative reaction to milk thistle. In addition, according to MayoClinic.com, some people experience side effects when taking the supplement. Reported symptoms include headaches, itching and an upset stomach.
