Milk Thistle Supplements Guide

Silymarin, or most commonly known as milk thistle is a type of herb that is closely related to the ragweed and daisy family. Originating from most Mediterranean countries, milk thistle is often used to help treat liver-related conditions such as hepatitis, gallbladder problems, and cirrhosis.

What is Milk Thistle?

Milk thistle has been used for over 2,000 years to help treat a number of health-related conditions such as gallbladder and liver problems.

Once initially grown in Mediterranean-based regions, milk thistle is now currently grown around the world. Milk thistle sprouts spiny-like branches that can grow upwards of 5 to 10 feet, with white blotches leaves. The way this plant gets its name is from the milky sap it excretes once its leaves are crushed. Milk thistle actually grows rather quickly, since it is often characterized as a week, and can fully grow within a year.

There are many forms that you can find milk thistle supplements in. You may choose to purchase your milk thistle supplement as a tincture, liquid extract, silymarin phosphatidylcholine complex, or as a capsule full of dried herb.

Also, those with alcohol related liver disease should refrain from taking a liquid extract as these usually contain alcohol.
