Herbal medicine is the art and science of using herbs for promoting health and preventing and treating illness. It has persisted as the world’s primary form of medicine since the beginning of time, with a written history more than 5000 years old. While the use of herbs in America has been overshadowed by dependence on modern medications the last 100 years, 75% of the world’s population still rely primarily upon traditional healing practices, most of which is herbal medicine.
