Muhammad bin Yazid Abu Hisham al-Rafa'i محمد بن يزيد أبو هشام الرفاعي · Chapters on Medicine

My father narrated that he heard the Messenger of Allah (s.a.w) saying: "There is nothing to Al-Ham, and the eye is real."

"It was narrated to me that Abu Hurairah said:'Ash-Shuniz is a cure for every disease except As-Sam.' Qatadah said: "One takes twenty-one seeds daily, and puts them in a cloth, then infuses (water) and sniffs two drops in his right nostril, and one drop in the left. The second (day) two drops are sniffed in the left, and one drop in the right. The third (day) two drops in the right and one drop in the left."

"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."
