Wild Indigo

Parts Used & Where Grown

The plant is native to the midwestern United States and continues to grow primarily in this region. The root of wild indigo is used medicinally.

How It Works

According to test tube experiments, the polysaccharides and proteins in wild indigo are believed to stimulate the immune system.1 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.2 The root also contains alkaloids, which may contribute to its medicinal actions.
