“Abu Ja’far, or abu al-Hassan, ‘Alayhim al-Salam, -uncertainty is from Muhammad ibn Musa- has said, ‘Once al-Sadab was mentioned and He (the Imam) said, ‘There are benefits in it. It increases the power of understanding, increases in the brain except that it putrefies one’s back’s water.’ It is narrated that it is very good for ear ache.”
