Zayn-e-Attar

Haji Zayn Attar (died c.1403) was a 14th-century Persian physician.
He served for sixteen years as the court physician to the Muzaffarid ruler Shah Shuja, who ruled from 1358 to 1384. Shah Shuja is famous for being the patron of the famous poet Hafiz of Shiraz.
Haji Attar's comprehensive Persian pharmacopoeia of simple and compound remedies, the "Ikhtiyarat-i Badi‘i" was apparently composed for the Muzaffarid princess Badi‘ al-Jamal, who is named in the title of the treatise but of whom very little is known.
