|“||Although classical societies advanced the studies of anatomy and physiology, prior to the scientific and industrial revolutions of the 18th and 19th centuries, medicine was an inexact science built on practical knowledge. First oral traditions and then written accounts passed down remedies and procedures that had been discovered through experience. The principal agent of healing was herbal medicine, the application or digestion of herbal compounds whose curative powers had been discovered through experiment. The presence of specialists in herbal medicine within a Middle Ages town or village was a boon to the inhabitants’ quality of life.||”|
