Senna Leaf is commonly known as senna or Alexandrian senna. Senna has been used since the
9th century by Arabian physicians as a laxative, and subsequently it has been known as the "cleansing
herb." Senna acts as a laxative and is primarily used for constipation, preoperative cleansing and weight
loss, and may also help with hypertension. Senna can also be used as an anti-inflammatory, for cellular
regeneration, and to treat anal fissures and hemorrhoids. As a paste, senna can be used to treat acne,
ringworm and other skin disorders.
