The plant thrives on plains and in forest undergrowth, where its spotted pale brown or purple flowers and long seed capsules distinguish it from other medicinal herbs.

The root is unearthed in spring or autumn, mostly in Virginia and North Carolina. Native Americans and European settlers commonly used fringe tree to treat inflammations of the eye, canker sores, and spongy gums. The Choctaw of Louisiana applied the mashed bark to cuts and bruises, and Native Americans in Alabama used the bark for toothache. In the 19th-century Anglo-American Physiomedicalist tradition, it was valued as a bitter tonic and was often used to aid recovery from long-term illness.

It has been used as a safe and effective laxative for thousands of years across Europe, North Africa, and Asia.
