Wild indigo is used for infections such as diphtheria, influenza (flu), swine flu, the common cold and other upper respiratory tract infections, lymph node infections, scarlet fever, malaria, and typhoid.
Some people apply wild indigo directly to the skin for ulcers, sore and painful nipples, as a douche for vaginal discharge, and for cleaning open and swollen wounds.
Wild indigo is frequently used by farmers, especially in Virginia and Maryland, to keep flies away from horses.
