On The Continuous Flowing Of Blood

Al-Mas’udi narrated from al-Hasan b. Khalid, who said: A woman wrote to Al-Ridha’, peace be upon him, complaining of a continuous flow of blood (dawam al-dam). He wrote to her: “Take, Allah willing, one handful of coriander (kuzbara) and one of sumac (summaq), and soak them for a night outdoors. Then boil them in a clay pot and drink a saucer of it. It will stop the blood flow except during the time of menstruation.”
