The root of wild indigo is used medicinally.
Uses
The polysaccharides and proteins in wild indigo are believed to stimulate the immune system. This might account for its role against the common cold and flu. Wild indigo is rarely used alone and is a part of a popular European product for colds and flu that combines the herb with echinacea and thuja. The root also contains alkaloids, which may contribute to its medicinal actions.
Used to treat ulcers and several types of infections, including those affecting the mouth and gums, lymph nodes, and throat.
