Asma' bint 'Umais narrated that the Messenger of Allah (S.A.W) asked her what they used as a laxative. She said: "Shubrum" He said: "It is hot and too strong." She said:"Then I used Senna as a laxative." So the Prophet (S.A.W) said: "If there was anything that would have a cure for death in it, then it would have been Senna."
