What did the Arab doctors discover?

Arab doctors made significant contributions to medicine during the Islamic Golden Age, particularly in the fields of pharmacology, surgery, and medical ethics. They established hospitals and medical schools, emphasizing empirical observation and experimentation. Notable figures like Avicenna (Ibn Sina) wrote influential medical texts, such as "The Canon of Medicine," which synthesized and expanded upon ancient Greek and Roman medical knowledge. Their work laid the groundwork for modern medicine and influenced both Eastern and Western medical practices.
