The dried leaves are used as a purgative and are chiefly obtained from S. acutifolia (Alexandria senna) and S. angustifolia (Indian senna); both trees are cultivated especially in S India. The wild senna (S. marylandica), a perennial of the E United States, has been similarly used. Golden shower (S. fistula) of India yields canafistula, a purgative extracted from the fruit pulp. The young shoots of several wild species are used for food and the seeds for a coffee substitute. S. nictitans, a North American herb, is sometimes called wild sensitive plant because its leaves respond to touch as do those of the true sensitive plant, a mimosa. Senna is classified in the division Magnoliophyta Magnoliophyta (măg'nōlēŏf`ətə)
