Medicine is the branch of health science and the sector of public life concerned with maintaining or restoring human health through the study, diagnosis and treatment of disease and injury. It is both an area of knowledge – a science of body systems, their diseases and treatment – and the applied practice of that knowledge.

Overview

---

Medical care is shared between the medical profession (physicians or doctors) and other professionals such as nurses and pharmacists, sometimes known as allied health professionals. Historically, only those with a medical doctorate have been considered to practice medicine. Clinicians (licensed professionals who deal with patients) can be physicians, nurses, therapists or others. The medical profession is the social and occupational structure of the group of people formally trained and authorized to apply medical knowledge. Many countries and legal jurisdictions have legal limitations on who may practice medicine.
