History of Herbal Medicine Herbal medicine is older than any other type of healthcare. Every culture has taken advantage of herbs and their benefits. Herbal medicine began with primitive cultures using different plants for shelter, clothing, and medicine. Man learned medicinal benefits of plants through trial and error methods in addition to observing animals. Man’s knowledge of herbs and their medicinal uses advanced over time. Even the pharmacopoeia of scientific medicine in the 20th century was developed primarily from native herbal lore. Herbal medicine continues to influence the medicines of today. Up to 25 percent of all prescription drugs in the United States have at least one active ingredient that comes from plant extracts or synthesized plant compounds.
As many as 4 billion people, or 80 percent of the earth’s population, are estimated to u

se a form of herbal medicine in their health care, according to the World Health Organization (WHO). Of the 119 plant-derived pharmaceutical drugs, as many as 74 percent are used in the same ways the plants were used by natives and Asian cultures.
