Milk Thistle: Nature's liver protector

Milk thistle is one of the most useful of all liver herbs. Kathryn Terrill explains why we could all use a dose of this amazing remedy.

Used medicinally for more than 2000 years, milk thistle (Silybum marianum) is native to the Mediterranean, but is now found across the world, including Australia.

The plant has white veins on its spiked greens leaves, which are fabled to carry the milk of the Virgin Mary.

This popular herb is known as a must-have for those in need of some liver antioxidant protection. Milk thistle has been historically applied as a treatment for a broad range of liver disorders, and this valuable remedy has also been the subject of scientific research in recent times.

A compound or flavonoid, called silymarin, is thought to be the main active ingredient in milk thistle. Silymarin is extracted from the seeds of the milk thistle plant.
