Milk thistle extract’s ability to inhibit inflammation may also be helpful in treating allergic asthma.

Insulin resistance can lead to type 2 diabetes. A 2016 study on mice showed that silymarin extracted from milk thistle had a positive effect on insulin levels. This is thought to be because of its anti-inflammatory properties.
