The jalap plant is native to the moist mountainous forests of Mexico. It is cultivated as a medicinal plant in Mexico, Central America, the West Indies, and India. The roots contain 8–12 percent resin, almost 95 percent of which consists of the glycoside convolvulin. Preparations made from dried roots are used as a strong laxative.
