Milk thistle (Silybum marianum) is a plant native to the Mediterranean region, known for its distinctive purple flowers and white-veined leaves. It has been used for centuries as a natural remedy for liver and gallbladder disorders. The active ingredient in milk thistle, silymarin, is believed to have antioxidant, anti-inflammatory, and hepatoprotective properties. Often taken in supplement form, milk thistle is commonly used to support liver health, manage liver diseases such as cirrhosis and hepatitis, and protect against toxins. Additionally, it is sometimes used to support skin health and manage cholesterol levels.
