Najm al-Din Mahmud ibn Ilyas al-Shirazi

Najm al-Din Mahmud ibn Ilyas al-Shirazi, was a Persian physician from Shiraz in Persia.

His major composition was a large Arabic medical compendium, Kitab al-Hawi fi ‘ilm al-tadawi (The Comprehensive Book on the Art of Curing), whose title often caused confusion with the better-known Kitab al-Hawi (The Comprehensive Book) written four centuries earlier by Rhazes.

In the course of his treatise, Najm al-Din al-Shirazi cites by name many earlier medical authorities, including Hippocrates and Galen as well as Arabic writers. Little is known of the life of Najm al-Din al-Shirazi. He died in the year 1330CE.
