Hippocrates (c. 460 - c. 370 BC) was a Greek physician, often called the founder of medicine.
Important Hippocratic ideas include cleanliness (for patients and physicians), moderation in earing and drinking, letting nature take its course, and living where the air is good.
He was born and practised on the island of Kos and died at Larissa. He is known to have discovered aspirin in willow bark.
The Corpus Hippocratkum, a grouping of some 70 works, is attributed to him, but was probably not written by him at all, although they outline the particular approach to medicine that he promulgated. They include the famous Aphorisms and the Hippocratic Oath which embodies the essence of medical ethics.
He believed that health was the result of the "humours" of the body being in balance; imbalance caused disease. These ideas were later adopted by Galen.
