Senna Seed

Wild Senna (Senna Hebecarpa) - Senna is an herb. The leaves and the fruit of the plant are used to make medicine. This native, long-lived, yellow flowering perennial is found in the eastern third of the United States. A unique specimen plant for the border! Long-lived and hardy. Tolerant of hot, dry sites once established. It is excellent for native gardens and meadows as well as conservation plantings. Plants grow up to six feet tall and produce yellow flowers in summer, which attract butterflies, bumble bees and other native bees. Seeds are eaten by some game birds such as quail and turkey. Plants prefer damp, fertile soils but will tolerate drier sites.

Senna is an herb that contains compounds called anthraquinones, which are powerful laxatives. In fact, the U.S. Food and Drug Administration has approved senna as a nonprescription laxative. Additionally, senna has been found to be effective for cleansing the bowel prior to undergoing colonoscopy when used in conjunction with other agents.
