Abstract

According to George Alfred Leon Sarton: "Razi was the greatest physician of Islam and in the Middle Ages." He was an Iranian scientist who wrote his books in Arabic, and so, he was called the Arab Galen. In medicine, his contributions were so significant that he was one of the most famous physicians until the 17th century in Europe. Some of the ideas he used in the treatment of modern medicine are still used, especially in patients treated with fluids and food. The largest and most important of al-Razi's medical books is Kitab Al-Hawi fi al-tibb. This book consists of definitions, classifications, causes, clinical manifestations, and management of diseases including nerve damage.
