Also known as Milk Thistle, Silybum Marianum is a spiny-leaved plant native to England or the Mediterranean region, with a long history in European medicine for liver support. Possessing a bitter taste and cool nature, it is widely believed to clear heat and toxins, soothe the liver, and promote bile flow. Silybum marianum is best known for its active compound silymarin—a potent flavonoid complex that modern research has shown to be anti-inflammatory, immunomodulatory, and antioxidant.
