- "I swear this oath by Apollo Physician by Aesculapius, by Health, and by all the gods and goddesses in whatsoever place that I enter, I will enter to help the sick and heal the injured. And I will do no harm."
A physician, also known as a medical doctor or medical practitioner, was an individual, typically a doctor, who practiced in the field of medical science. It was a physician's duty to save the lives of ailing patients, while at the same time preserving the life of healthy patients. (TOS: "The Enterprise Incident"; VOY: "Tuvix", "Retrospect", "Survival Instinct"; ENT: "Fortunate Son")
As a physician, Beverly Crusher explained that "it's often my job to give people unpleasant news, to tell them they need surgery, or they can't have children, or that they might be facing a difficult illness." (TNG: "All Good Things...") It was also a requirement of a medical practitioner to have a certain sensitivity to properly address a patient. (VOY: "Parallax")
