This herb may temporarily help lower symptoms of menopause, menstrual cramps, difficult menstrual periods, reproductive problems in females, high blood pressure, arthritis, allergies, and asthma, increase immune system function.
It is chiefly used for its alterative properties, being a useful purgative in disorders of the liver and duodenum, and is an ingredient of many compounds for purifying the blood. It acts as a stimulant to the liver and intestinal glands and is used in constipation and biliousness, and is believed by some to be a hepatic stimulant second only to podophyllin, but if given in full doses it may occasion considerable nausea and severe prostration.
Its chief use is for syphilis and some forms of low-grade scrofula and skin affection. It is also valuable in dropsy.
