barberry

Medicinal use of barberry dates back more than 2,500 years. It has been used in Indian folk medicine to treat diarrhea, reduce fever, improve appetite, relieve upset stomach, and promote vigor, as well as a sense of well being. Today, it is widely used for medicinal purposes in Iran, including for biliary disorders (such as gallbladder disease) and heartburn.

Barberry and goldenseal (Hydrastis canadensis) are often used for similar medicinal purposes because both herbs contain the chemical berberine. Berberine has been shown to inhibit the growth of bacteria in test tubes, and may help the immune system function better. The aqueous extract of barberry has beneficial effects on both the cardiovascular and neural system. As such, it may be useful in the treatment of hypertension, tachycardia (rapid heartbeat), and some neuronal disorders, such as epilepsy and convulsions. Recent studies suggest that barberry also has antioxidant properties, and may help prevent certain types of cancer.
