The root is the active part of the plant, it is harvested in the autumn after the plant has died down and is dried for later use. It is said to be antiperiodic, antiseptic, astringent, cholagogue, diuretic, laxative, stomachic, tonic. It is used mainly in the treatment of disorders affecting the ears, eyes, throat, nose, stomach, intestines and vagina. The root contains the alkaloids hydrastine, berberine and canadine. Berberine is antibacterial (effective against broad-spectrum bacteria and protozoa), it increases bile secretions, acts as an anticonvulsant, a mild sedative and lowers blood pressure. Use of this plant destroys beneficial intestinal organisms as well as pathogens, so it should only be prescribed for limited periods (a maximum of three months). The plant should be used with caution, and not at all during pregnancy or by people with high blood pressure.An infusion of the root is used externally as a wash for skin diseases, vaginal infections, gum diseases etc.

Plants are hardy to at least -15°c.Goldenseal is grown commercially as a medicinal plant, but it is not easy to establish the plants. Another report says that all goldenseal root that is used medicinally comes from wild plants. Since the plant is becoming increasingly rare in many parts of its range, it is probably wise to try and find alternatives to this species for medicinal use unless you can be sure that your supply comes from cultivated plants[K].
