Many plants have traditional medical uses. Ethnobotanists and pharmacognacists catalog and study these plants and uses. This is a list of some of the more common medicinal properties that are ascribed to plants. Many of these terms are still used in modern pharmacology. The modern biochemical study of the physiological effects of drugs on the body is called pharmacodynamics.
