<unk>  is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health.<unk>  encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary<unk>  applies biomedical sciences, biomedical research, genetics, and<unk> ical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction,<unk> ical devices, biologics, and ionizing radiation, amongst others.<unk>  has been practiced since prehistoric times, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and philosophical beliefs of local culture. For example, a<unk>  man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism. In recent centuries, since the advent of modern science, most<unk>  has become a combination of art and science (both basic and applied, under the umbrella of<unk> ical science). While stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science. Prescientific forms of<unk>  are now known as traditional<unk>  or folk<unk> , which remains commonly used in the absence of scientific<unk> , and are thus called alternative<unk> . Alternative treatments outside of scientific<unk>  having safety and efficacy concerns are termed quackery.
