Medicinal use: This remedy has a wide application in the treatment of skin disease, apparently aiding the skin by working through the liver, the main detoxifying organ of the body.

It may be used wherever there is constipation associated with liver problems or the gall bladder. It has stimulating effects on the liver, gallbladder, pancreas, and colon and promotes the production and secretion of bile along with other hepatic functions making it useful in many toxic conditions.
