Psoralea is a genus in the legume family (Fabaceae). Although most species are poisonous, the starchy roots of P. esculenta (breadroot, tipsin, or prairie turnip) and P. hypogaea are edible.

Psoralea corylifolia is an important plant in the Indian Ayurveda system of medicine, and also Chinese medicine. The seeds of this plant contain a variety of coumarins including psoralen. The seeds have a variety of medicinal uses, but the specific role (if any) of psoralen in these uses is unknown. Psoralen itself has a number of commercial uses.
