Description:
Silybum marianum is an annual or biennial plant of the Asteraceae family. This fairly typical thistle has red to purple flowers and shiny pale green leaves with white veins. Originally a native of Southern Europe through to Asia, it is now found throughout the world. Several scientific studies suggest that substances in milk thistle (especially a flavonoid called silymarin) protect the liver from toxins. Silymarin has antioxidant and anti-inflammatory properties, and it may help the liver repair itself by growing new cells.

Function:
1.Milk thistle P.E. provides hepatocellular protection by stablizing hepatic cell membranes.
2.Milk thistle P.E. alters the structureof the outer cell membrane of the hepatocytes in such a way as to prevent the penetration of the liver toxins into interior of the cell.
3.Silymarin has the stimulation effect on nucleolar polymerase A results in an increase in ribosomalprotein synthesis,and thus increase the regenerative ability of the liver and formation of new hepatocytes.
4.Silymarin as other actions include interruption of enterohepatic recirculation of toxins and regeneration of damaged hepatocytes.
Application:
1. Silymarin extract is widely used in medicine, health products, food and cosmetics;
2. Protecting liver cell membrane and improving the liver function;
3. Detoxification, reducing the blood fat, benefiting the gallbladder, protecting the brain and removing the free ra dical of body. As a kind of better antioxidant, it can clear free radical in human body, postpone senility;
4. Silymarin extract has the function of radiation hardening, arteriosclerosis preventing, and skin-aging
