Silymarin is a  flavonoids complex composed of silibinin, silidianin, and silicristin. It is thought to help fight  free radicals in the liver due to its powerful antioxidant properties. Thistle benefits are  attributed to the active ingredient Silymarin, which is found in milk thistle.

A study done in 2006 confirmed the potential benefits of milk thistle in  improving diet-induced liver damage. One of the largest organs in the body, the liver is  responsible for detoxifying toxic substances. It protects the liver's numerous hepatic cell  membranes and slows toxins from being absorbed into the liver. Milk thistle may protect  your liver from various effects of alcohol.

Furthermore, milk thistle  has a powerful antioxidant effect that reduces the risk of diabetic kidney disease. According  to a study published in 2014 that looked at both animal and human studies, milk thistle has  "demonstrated beneficial effects on diabetic complications, including diabetic neuropathy,  diabetic nephropathy, and non-alcoholic steatohepatitis, due mostly to its anti-oxidant properties. 

Promotes lactation (2) 

In lactating women, milk thistle is a proven natural remedy for increasing milk production.  According to two reviews, milk thistle (and fenugreek) is recommended for use as  galactagogues for milk production. Traditional methods for administration include taking 1- 3g of the crushed seeds (encapsulated) or crushing the seeds and preparing tea from them. A single study has been conducted using 420mg of micronized Silymarin which increased  milk production by 64% on day 30 of supplementation compared to 22% in the placebo  group, with increased measurements on day 63 of 86% and 32%. Thus, it has shown to help  improve the lactation and that is why it is also known as a galactogogue.
