Medicine is the art and science of healing. It encompasses a range of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies health science, biomedical research, and medical technology to diagnose and treat injury and disease, typically through medication, surgery, or some other form of therapy. The word medicine is derived from the Latin ars medicina, meaning the art of healing. Though medical technology and clinical expertise are pivotal to contemporary medicine, successful face-to-face relief of actual suffering continues to require the application of ordinary human feeling and compassion, known in English as bedside manner.
History
Prehistoric medicine incorporated plants (herbalism), animal parts and minerals. In many cases these materials were used ritually as magical substances by priests, shamans, or medicine men. Well-known spiritual systems include animism (the notion of inanimate objects having spirits), spiritualism (an appeal to gods or communion with ancestor spirits); shamanism (the vesting of an individual with mystic powers); and divination (magically obtaining the truth). The field of medical anthropology studies the various prehistoric medical systems and their interaction with society.
Early records on medicine have been discovered from early Ayurvedic medicine in the Indian subcontinent, ancient Egyptian medicine, traditional Chinese medicine, the Americas, and ancient Greek medicine. Early Grecian doctors Hippocrates, who is also called the Father of Modern Medicine, and Galen laid a foundation for later developments in a rational approach to medicine. After the fall of Rome and the onset of the Dark Ages, Islamic physicians made major medical breakthroughs, supported by the translation of Hippocrates' and Galen's works into Arabic. Notable Islamic medical pioneers include polymath Avicenna, who is also called the Father of Modern Medicine, Abulcasis, the father of surgery, Avenzoar, the father of experimental surgery, Ibn al-Nafis, the father of circulatory physiology, and Averroes. Rhazes, who is called the father of pediatrics, first disproved the Grecian theory of humorism, which nevertheless remained influential in Western medieval medicine. While major developments in medicine were occurring in the Islamic world during the medieval period, the Western world remained dependent upon the Greco-Roman theory of humorism, which led to questionable treatments such as bloodletting. Islamic medicine and medieval medicine collided during the crusades, with Islamic doctors receiving mixed impressions. As the medieval ages ended, important early figures in medicine emerged in Europe, including Gabriele Falloppio and William Harvey.

Practice
The practice of medicine combines both science as the evidence base and art in the application of this medical knowledge in combination with intuition and clinical judgment to determine the treatment plan for each individual patient.
Central to medicine is the patient-physician relationship established when a person with a health concern seeks a physician's help; the 'medical encounter'. Other health professionals similarly establish a relationship with a patient and may perform various interventions, e.g. nurses, radiographers, and therapists.
As part of the medical encounter, the healthcare provider needs to:
develop a relationship with the patient
gather data (medical history, systems inquiry, and physical examination, combined with laboratory or imaging studies (investigations))
analyze and synthesize that data (assessment and/or differential diagnoses), and then:
develop a treatment plan (further testing, therapy, watchful observation, referral and follow-up)
treat the patient accordingly
assess the progress of treatment and alter the plan as necessary (management).
The medical encounter is documented in a medical record, which is a legal document in many jurisdictions.
