Milk Thistle’s Key Compound: Silymarin Originates from Its Seeds
Milk Thistle supplements are made from the seeds of the Silybum marianum plant, which contain an active group of plant compounds called silymarin. Silymarin is valued for its antioxidant properties and is the main reason this ingredient is included in many botanical blends. The distinctive purple flower of the milk thistle gives way to spiky seed heads, where silymarin is concentrated.
