Silymarin - Milk Thistle (Silybum marianum)

Silymarin is derived from Milk Thistle (seed extract from the flower of silymarin plant). The Milk thistle herb is a flowering plant of Silybum Adans genus, a member of the daisy family (Asteraceae). It grows mainly in North Africa, the Mediterranean region and the Middle East (now also grown in the U.S.) but is marketed and is widely available in the Philippines as a herbal liver supplement (silymarin capsules, trademark: Liveraide). Silymarin and milk thistle are frequently used interchangeably.

Experiments laboratory on animals (rats, baboons, dogs) shows silymarin works by modifying hepatic cell membranes in a way, prevents liver toxins from entering the interior of the cells. The toxins that may damage the liver are expelled through the kidneys instead. Silymarin is a polyphenolic flavanoid consisting of three chemicals: silybin, silicristin and silidianin which are antioxidants that neutralizes and breaks down free radicals. When there is an existing liver damage,silymarin also helps repair the damage and help regenerate new liver cells but is unlikely to help in the late stages of liver cirrhosis.


Many studies have been published on the health benefits of milk thistle and silymarin on humans but many are inconclusive or poorly done. Further studies are needed to fully appreciate the health benefits of silymarin on humans. However, anecdotal data suggests that it helps alleviate liver diseases and other aliments.
Since most commercial silymarin and milk thistle products are marketed as herbal supplements, they are not subjected to the same stringent standards imposed on prescription drugs. Their safety, purity and quality vary from brand to brand. In very rare instances, silymarin can cause headaches, upset stomach and joint pains. Silymarin is not recommended during pregnancy. Dozes over 1.5 grams a day may cause diarrhoea. It is recommended that you consult with your doctor or a health care provider before taking silymarin herbal supplements, liver supplements or any herbal medicine.
