Sābūr ibn Sahl (Persian: شاپور بن سهل گندیشاپوری; d. 869 CE) was a 9th-century Persian[1] Christian physician from the Academy of Gundishapur.
Among other medical works, he wrote one of the first medical books on antidotes called Aqrabadhin (Arabic: القراباذين), which was divided into 22 volumes, and which was possibly the earliest of its kind to influence Islamic medicine. This antidotary enjoyed much popularity until it was superseded Ibn al-Tilmidh's version later in the first half of twelfth century.
