Hippocrates was an ancient Greek physician and was considered one of the history's most famous doctor and most outstanding figures in the history of medicine.
Hippocrates stated that medicine is not philosophy, and therefore must be practiced on a case-by-case basis rather than from general, first principles.
He separated medicine from philosophic speculation, rejected superstition in favor of scientific observation, classified diseases, and gave the world the Hippocratic Oath, a code of ethics for physicians which is still taken by graduates at many modern medical schools.
In "The Sacred Disease", he advocated clinical observations, diagnosis, and prognosis, and argued that specific diseases come from specific causes.
Diseases in the Corpus Hippocraticum are natural events, which arise in a normal manner from the food one has eaten or weather, Airs, Waters, and Places, which recognized a link between environment and disease.
He was an expert in diagnosis, predicting the course of disease. Based on the color and pallor of the ill person, disease was considered to be an imbalance of the four "humors"—blood, phlegm, yellow bile, and black bile.
This concept persists in the following terms that describe distinctive temperaments, which were determined by the predominance of the distinct fluid: sanguine (blood), phlegmatic (phlegm). choleric (yellow bile), and melancholic (black bile).
Healing emphasis was placed on purges, attempts to purify the body from the illness produced by excesses or imbalance of humors. Hippocrates laid the foundation of a rational nutrition.
He particularly noted the influence of food and diet on health, recommending moderation.
He believed that the goal of medicine should be to build the patient's strength through appropriate diet and distinct hygienic measures, resorting to more drastic treatment only when the symptoms showed this to be necessary.
He watched the course of ilness, and attached great importance to the various periods of disease. Knew and used in medical practice more than 200 medicinal herbs, was a supporter of massage, gymnastics and water therapies
Hippocrates also known as an outstanding surgeon.
The Hippocratic Collection (Corpus Hippocraticum) was assembled for the Library of Alexandria in Egypt. About 60 medical writings have survived that bear Hippocrates' name, most of which were not written by him. The collection deals with anatomy, clinical subjects, diseases of women and children, prognosis, treatment, surgery, and medical ethics.
He is credited with the Hippocratic Oath, a code of professional conduct still followed by doctors.
When he was twenty years old he was devoted to the priests, because it was impossible in that date to be engaged in his medical practice without it.
He then seems to have spent most of his life traveling around the Greek world curing the great of obscure diseases and ridding grateful cities of plagues and pestilence. He taught and practiced his profession at Athens, probably also in Thrace, Thessaly, Delos, his native island Kos and the Sea of Marmara.
Hippocrates was born on the island of Cos. The two sons of Hippocrates, Thessalus and Draco, and his son-in-law, Polybus, were his students. He traveled to many neighboring countries, and taught and practiced his profession at Athens, probably also in Thrace, Thessaly, Delos and his native island. He probably died in Larissa at the age of 90.
