What is Medicine?

Medicine is a study of both Prevention and Cure of all Health problems. Which includes treatment, diagnosis, prevention of disease, medical research, and many other aspects of health.

Medicine has been there from ancient times during most of which was an art, skill, and knowledge, which was connected with the religious and philosophical beliefs of that local culture. For example, a man applies herbs and says prayers for healing or an ancient philosopher and physician would apply many different thoughts according to their theories. In recent centuries, since the advent of modern science, most medicine has become a combination of art and 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 medicine are now known as traditional medicine, though they do not fall within the modern definition of “medicine” which is based on medical science.

Wherever the art of medicine is loved, there is also a love of humanity.

Hippocrates (Father of Western Medicine)
