Wild indigo was a favorite medicine of the N. American Indians, a decoction of the roots being used as an antiseptic wash for wounds and skin complaints. Modern research has shown that this acrid bitter herb stimulates the immune system and is particularly effective against bacterial infections. Caution is advised in the internal use of this plant, large or frequent doses are potentially harmful.

A tea made from the roots is cholagogue, emetic, febrifuge and purgative. The fresh root is also considered to be antiseptic, astringent and laxative. The infusion is used in the treatment of upper respiratory infections such as tonsilitis and pharyngitis, and is also valuable in treating infections of the chest, gastro-intestinal tract and skin. The plants antimicrobial and immune-stimulant properties combat lymphatic problems, when used with detoxifying herbs such as Arctium lappa it helps to reduce enlarged lymph nodes.

Wild indigo is frequently prescribed, along with Echinacea, in the treatment of chronic viral infections or chronic fatigue syndrome. A decoction of the root soothes sore or infected nipples and infected skin conditions. When used as a mouth wash or gargle the decoction treats mouth ulcers, gum infections and sore throats.

The fresh root, including the bark, is used to make a homeopathic medicine. This has a limited range of action, but is used especially in the treatment of certain types of flu.

Known Hazards: The plant is poisonous in large quantities.
