Senna Leaf: Benefits, Side Effects, and Safe Usage Guidelines

Senna leaf, derived from Cassia acutifolia (also known as Senna alexandrina), has been used for centuries as a natural laxative and digestive aid. Native to India, Pakistan, and China, this desert flowering plant belongs to the bean family and is available over-the-counter as dried root, liquid extract, tablets, and tea.

How Senna Works

The active compounds in senna are anthraquinone glycosides called sennosides. These stimulate the smooth muscles of the intestines, increasing stool volume and peristaltic contractions to promote bowel movements. This makes senna effective for constipation relief and colon cleansing, often recommended post-rectal surgery or for hemorrhoids.
