Hippokrates

Hippocrates was a famous Greek physician who is considered the father of medicine. He believed that diseases had natural causes and not supernatural ones, and that observation and diagnosis were essential for medical practice. He also developed a code of ethics for physicians, known as the Hippocratic Oath, which is still used today. Some of his beliefs were based on the theory of the four humors, which stated that health depended on the balance of four fluids in the body: blood, phlegm, yellow bile and black bile. He also believed in the healing power of nature and diet, and advocated for moderation and hygiene

The Hippocratic Oath is a code of ethics that is traditionally attributed to Hippocrates and his students. It is one of the oldest and most famous texts on medical ethics in the Western world. It requires new physicians to swear by various healing gods and to uphold certain principles and standards of conduct while practicing medicine. Some of these principles include respecting their teachers and colleagues, treating their patients with beneficence and non-maleficence, avoiding harm and injustice, keeping confidentiality, refraining from giving deadly drugs or performing abortions, and living a moral life12. The original oath was written in ancient Greek and has been translated and revised many times over the centuries. The modern versions of the oath are usually shorter and more secular, and reflect the changes in medical practice and society
