The document provides an overview of Islamic medicine between the 11th and 15th centuries. It discusses how Islamic ideas influenced the understanding of disease causation and led to advances in hospitals, surgery, anatomy, and chemistry. Key individuals mentioned include Rhazes, who distinguished between smallpox and measles, and Avicenna, whose Canon of Medicine was influential in Europe. Hospitals were established in Baghdad and other cities, and surgeons like Albucasis described various surgical procedures.
