Latin Name
Cassia senna

General Description
Senna is a powerful laxative that should not be taken lightly. This woody shrub contains colon-stimulating chemicals known as anthraquinones, which in high doses act as cathartics, or extremely strong laxatives. Both leaves and seedpods are used medicinally, although the pods are milder. Anthraquinones, derived from senna and other herbs, are among the ingredients of many commercial laxatives. The medicinal use of senna dates to ancient civilizations; it was introduced into European medicine by Arab healers in the ninth century. The herb grows primarily in India and Egypt.
