Herbal medicine is the study of medicinal plants. Although there is limited scientific evidence for the efficacy of herbs, they are still the basis for traditional medicine. Herbal medicine is based on pharmacognosy, or the study of pharmacology. This is a field of study that has a broad range of application in traditional and alternative health care. The science of pharmacognosy is a fundamental part of the practice of herbal medicine.
