Which Greek physician from the 4th Century B.C. is known as the father of medicine?

The title "Father of Medicine" belongs to a Greek physician who revolutionized how we think about health and disease. Living during the Classical Age of Greece in the 5th and 4th centuries B.C., Hippocrates of Kos was one of the first to argue that diseases were caused by natural forces, not by the anger of the gods. He insisted that careful observation and rational thought were the keys to understanding and treating illness, effectively separating the practice of medicine from religion and superstition for the first time in Western history.

His teachings are collected in a body of work known as the Hippocratic Corpus, which details a systematic approach to clinical practice. These texts introduced concepts like diagnosis, prognosis, and the importance of a clean environment. While his theory of the "four humors" (blood, phlegm, yellow bile, and black bile) has long been disproven, it represented a monumental attempt to explain the body's inner workings without resorting to the supernatural (Review).

Perhaps his most enduring legacy is the Hippocratic Oath, a code of professional ethics that has guided physicians for centuries. This pledge to practice medicine ethically and to prioritize the well-being of the patient established a moral foundation (Review) for the medical profession that continues to influence doctors around the world
