The Kitab al-Hawi

The Kitab al-Hawi is a comprehensive medical encyclopedia compiled by the Persian physician al-Razi (Rhazes) in the 9th century. It organises medical knowledge into detailed sections covering diseases, treatments, pharmacy, and anatomy. The text integrates classical Greek and Roman medical theories with his own clinical insights, making it a valuable reference for physicians. Its systematic approach and broad scope helped advance medical practice in the Islamic world and later in Europe, influencing the development of medicine for centuries.
