Medicine is the science and practice of the diagnosis, treatment, and prevention of disease.
The word medicine is derived from Latin medicus, meaning "a physician."

Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through other diverse therapies.
