Senna hebecarpa, commonly known as wild senna, is a North American native plant growing on damp soils in Ontario, the east coast of the United States, south to Georgia and as far west as Wisconsin. Despite its vigour and mass production of seeds (of which only 10-30% are viable) in cultivated situations, this plant is considered endangered. Wild senna grows along roadways, disturbed areas, fields and the edge of streams. However, changes in hydrology, development of land and succession of secondary species are thought to be reducing its numbers.
Medicinal uses of Senna hebecarpa are extensive, ranging from curing cramps to administering for fainting spells. The extensive collecting of this plant for medicinal purposes (PDF) is also thought to contribute to the decline of this species in the wild.
