Milk thistle nutritionally supports the liver's ability to maintain normal liver function. It has shown positive effects in treating nearly every known form of liver disease, including cirrhosis, hepatitis, necroses, and liver damage due to drug and alcohol abuse. Milk thistle works due to its ability to inhibit the factors responsible for liver damage, coupled with the fact it stimulates production of new liver cells to replace old damaged ones.
Milk thistle has been proven to protect the liver from damage. The detrimental effects of environmental toxins, alcohol, drugs and chemotherapy may be countered with this valuable herb. The active chemical component in the herb is silybin, which functions as an antioxidant and is one of the most potent liver protective agents known. Clinical trials have proven silybin to be effective in treating chronic liver diseases and in protecting the liver from toxic chemicals. Silymarin, is actually a mixture of the herb's active components, including silybinin (also called silibinin or silybin).
