Senna(Cassia angustifolia): Senna is a laxative from the leaves and pods of the senna plant, a member of the pea family that is derived from ancient Arabic medicine. In Europe and in the United States, extracts from senna are approved in over-the-counter stimulant laxative products. The German government has approved senna for all conditions in which constipation and the need for soft stools is indicated. There are no known adverse side effects connected with the use of senna, other than those normally associated with the use of stimulant laxatives, in which case, long-term use or misuse can result in dependency and electrolyte loss.⁸⁹ Like other stimulant laxatives, senna should not be used during pregnancy or lactation unless professionally supervised.
