Milk thistle has been used in traditional herbal practices for centuries. Today, people are interested in its active ingredients, particularly silymarin, which is found in milk thistle extract. Studies and traditional use suggest that milk thistle may support:

• Liver function, liver diseases, or liver disorders
• Healthy blood sugar levels (related to type 2 diabetes)

There is also ongoing research into its possible role in areas like breast cancer, but no conclusions have been approved by health authorities.
