Sennas are purgatives that contain anthraquinone derivatives and their glucosides as active components. Sennosides or senna glycosides are the latter.
Senna works on the lower gut and is particularly effective at relieving constipation. It causes the colon’s peristaltic motions to intensify. Infusions are the most common way to prepare plants.
Senna is a genus of plants that includes herbs, shrubs, and trees. The leaves are pinnate, having leaflets that are oppositely paired. The inflorescences are racemes at the terminals of branches or sprouting from the leaf axils.
