B. Ibn al baitar
Diyāʾ al-Dīn Abū Muḥammad ʿAbd Allāh ibn Aḥmad al-Mālaqī, commonly known as Ibn al-Bayṭār (1197–1248 AD) was an Andalusian Arab physician, botanist, pharmacist, and scientist. His main contribution was to systematically record the additions made by Islamic physicians in the Middle Ages, which added between 300 and 400 types of medicine to the one thousand previously known since antiquity. He was a student of Abu al-Abbas al-Nabati.
