Medicine (also called conventional, orthodox, scientific, or mainstream medicine, especially in connection with alternative medicine, UK English i/ˈmɛdsɨn/, US English i/ˈmɛdɨsɨn/) is the field of applied science related to the art of healing by diagnosis, treatment, and prevention of disease. It encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness in human beings.
Contemporary medicine applies biomedical sciences, biomedical research, genetics and medical technology to diagnose, treat, and prevent injury and disease, typically through medication or surgery, but also through therapies as diverse as psychotherapy, external splints & traction, prostheses, biologics, pharmaceuticals, ionizing radiation among others.
The word medicine is derived from the Latin ars medicina, meaning the art of healing.
