Death cap can lead to liver damage and liver failure and is responsible for most deaths worldwide brought by eating foraged mushrooms. Silymarin has been reported to help fight off the mushrooms’ toxins.

Beneficial For Skin Health

Milk thistle also contains antioxidants that are beneficial to the skin. Study shows that silymarin and silybin extracts from milk thistle can help protect the skin cells against harmful solar UV radiation.

Also, milk thistles contain antioxidant and anti-inflammatory effects that can help promote healthy skin. Research has shown these advantageous effects in studies done in 2015 – milk thistle improves inflammatory conditions when applied to the mice’s skin. 

Benefits Of Milk Thistle

Helps Prevent Heart Disease

Hyperlipidemia is a heart complication that can cause things like atherosclerosis and atherosclerosis associated conditions, such as Coronary Heart Disease (CHD), peripheral vascular disease, and ischaemic cerebrovascular disease. Treatment with silybin from milk thistle has shown significant effects on preventing the development of CHD by lowering total cholesterol, triglycerides, and low-density lipoprotein (LDL).

Supports Weight Loss

According to studies done in 2016, Silymarin can tend to metabolic dysfunction associated with diet-induced obesity. In this study, mice were fed a high-fat diet that resulted in obesity but significantly lost weight after consuming Silymarin.

Positive Effects On Type-2 Diabetes

Milk thistle has shown beneficial effects on several diabetic complications, including diabetic neuropathy and diabetic nephropathy based on studies. The benefit of milk thistle for Type-2 diabetes has been characterized by decreasing insulin resistance. In a trial study done in 2006, 200mg treatment with Silymarin thrice a day has dramatically enhanced blood sugar control.

Alleviates Allergic Asthma Symptoms

Allergic asthma is a chronic inflammatory disease distinguished by an overreaction of the human immune system to an unknown allergen that is either eaten, injected, inhaled, or touched. This immune overreaction can pose symptoms such as sneezing, runny nose, itchy eyes, irritated throat, coughing, hives, rashes, asthma attacks, difficulty in breathing, and even death.  Silibinin has been reported to inhibit its inflammatory response by producing immunoglobulins which can alleviate allergic asthma symptoms.

Assists In Bone Health

In a study conducted in mice with tibial fracture, Silymarin supplementation has shown increased bone mineral density. On the other hand, Silibin shows anti-hepatotoxic properties that contribute to osteoprotective effects. Silibin also promotes the formation of osteoblasts that helps increase bone density.
