Milk Thistle Plant Extract Powder Silybin CAS No. 22888 70 6 Preventing Liver Disorder




Plant Source of Milk Thistle Extract:

Milk thistle is commonly found growing wild in a variety of settings, including roadsides. The Latin name is Silybum marianum. The seeds of the dried flower are used. The active ingredient in the plant is a flavonoid called silymarin, an antioxidant said to protect liver cells from toxins. Silymarin apparently promotes liver cell protein synthesis and decreases the oxidation of glutathione. The plant's flowers and seeds have been used for more than 2,000 years to treat disorders of the liver and gallbladder.

Silibinin (INN), also known as silybin (both from Silybum, the generic name of the plant from which it is extracted), is the major active constituent of silymarin, a standardized extract of the milk thistle seeds, containing a mixture of flavonolignans consisting of silibinin, isosilibinin, silicristin, silidianin, and others. Silibinin itself is a mixture of two diastereomers, silybin A and silybin B, in approximately equimolar ratio. The mixture exhibits a number of pharmacological effects, particularly in the liver.



Liver protection

Silibinin is available as drug (Legalon SIL (Madaus) (D, CH, A) and Silimarit (Bionorica), a Silymarin product) in some EU countries and used in the treatment of toxic liver damage (e.g. IV treatment in case of death cap poisoning); as adjunctive therapy in chronic hepatitis and cirrhosis.


Silibinin is under investigation to see whether it may have a role in cancer treatment (e.g. due to its inhibition of STAT3 signalling).


Silibinin also has a number of potential mechanisms that could benefit the skin. These include chemoprotective effects from environmental toxins, anti-inflammatory effects, protection from UV induced photocarcinogenesis, protection from sunburn, protection from UVB-induced epidermal hyperplasia, and DNA repair for UV induced DNA damage (double strand breaks).
