Medicine
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. 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 therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Physician
A physician, medical practitioner, medical doctor, or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.
Physician
For we are not all equally afflicted with the same disease or all in need of the same severe cure. This is the reason why we see different persons disciplined with different crosses. The heavenly Physician takes care of the well-being of all his patients; he gives some a milder medicine and purifies others by more shocking treatments, but he omits no one; for the whole world, without exception, is ill (Deut 32:15).

Medicine
No cataplasm so rare,
Collected from all simples that have virtue
Under the moon, can save the thing from death.
William Shakespeare, Hamlet (1600-02), Act IV, scene 7, line 144.
Medicine
How does your patient, doctor?
Not so sick, my lord,
As she is troubled with thick-coming fancies.
William Shakespeare, Macbeth (1605), Act V, scene 3, line 37.
