Arab physicians of the 9th century — including Masawaiyh and later Ibn Sina (Avicenna) — prescribed senna as a safe purgative, distinguishing it from the harsher mineral cathartics of their era. The leaves were traded along caravan routes from Nubia and Sudan to the ports of Alexandria, giving the plant its species name. By the medieval period, senna had entered European pharmacopoeias through the School of Salerno and became a standard hospital remedy throughout the Ottoman Empire.\u003c\/p\u003e\n\u003cp\u003eIn Ayurvedic medicine, senna (\u003cem\u003eSanay\u003c\/em\u003e) is classified as a \u003cem\u003eRechana\u003c\/em\u003e (purgative) herb.
