The Oath and Law by Hippocrates is a document that outlines the ethical code of conduct for medical practitioners. It is one of the most important documents in the history of medicine, as it established principles that are still used today. The Oath and Law calls for physicians to treat their patients with compassion and respect, to always act in their best interests, and to never do harm. These principles help to ensure that patients receive quality care and that physicians uphold their ethical obligations.
