The Hippocratic oath was introduced in ancient Greece as a guide to behaviour for new physicians. It was incorporated into medical practice in the Islamic Empire. Since then it has been forgotten, rediscovered, rewritten and reused.The Hippocratic oath was probably compiled by several authors following Hippocrates’ philosophical principles.


Its most basic principle was that a doctor must always cure patients, but never harm them. It also discussed respecting teachers, passing medical knowledge to new generations and keeping patients’ secrets. Many of these principles are still part of medical culture.

The return of the Hippocratic oath

The modern Hippocratic oath was used again in the 1940s, as a symbol of medical ethics. At the end of the Second World War, the world learned about Nazi atrocities committed on prisoners. Nazi scientists such as Josef Mengele used people in experiments to test the effects of radiation or high altitude and cold. Others gave untested vaccines to prisoners, then infected them with a deadly disease and counted how many survived. They claimed they were advancing medical knowledge.
