Milk Thistle - Silymarin Extract

Milk Thistle Extract (Silybum marianum)

Milk Thistle (Silybum marianum) is a flowering herb native to the Mediterranean region with a documented history of use in Western herbal medicine spanning over 2,000 years. Revered in traditional European herbalism as a primary herb for liver and gallbladder wellness, Milk Thistle has been used by herbalists and physicians since antiquity for digestive and hepatic support. Silymarin — the naturally occurring flavonolignan complex extracted from the seeds — is the primary marker of Milk Thistle quality and potency, and one of the most extensively researched naturally occurring compounds in the context of liver wellness in contemporary botanical science. This extract is prepared in 60% alcohol from wildcrafted Silybum marianum seeds.
