What medical advances happened during the Abbas caliphate?

During the Abbasid Caliphate, which lasted from the 8th to the 13th centuries, significant medical advances were made, particularly through the translation and preservation of Greek and Roman texts. The establishment of hospitals, known as bimaristans, improved healthcare access and medical education. Prominent figures like Al-Razi and Ibn Sina (Avicenna) contributed to the fields of surgery, pharmacology, and the understanding of diseases, with Ibn Sina's "The Canon of Medicine" becoming a foundational text in both the Islamic world and Europe for centuries. These advances laid the groundwork for modern medicine.
