Medicine is the science and "art" of maintaining and/or restoring human health through the study, diagnosis, and treatment of patients. The term is derived from the Latin ars medicina meaning the art of healing.

The modern practice of medicine occurs at the many interfaces between the art of healing and various sciences. Medicine is directly connected to the health sciences and biomedicine. Broadly speaking, the term 'Medicine' today refers to the fields of clinical medicine, medical research and surgery, thereby covering the challenges of disease and injury.
