Wild Indigo (Baptisia tinctoria), also known as yellow wild indigo, is a perennial plant native to North America.
Indigenous peoples used the plant for its antiseptic and anti-inflammatory properties, treating infections and wounds. Early European settlers also valued wild indigo for its medicinal uses, and it became a popular remedy for infections and fever.
The plant contains alkaloids and glycosides that have immune-stimulating and antimicrobial effects.
In modern herbal medicine, wild indigo is used to boost the immune system, treat infections, and support lymphatic health. Its strong antiseptic properties make it effective for external use on wounds and skin conditions.
