Herbal medicine refers to using plants for medicinal purposes and has been practiced for millennia. It is the second most popular form of alternative medicine. While herbal medicines were widely used in the 19th century, the rise of chemical analysis and synthesized drugs caused their use to decline. However, the WHO estimates that 80% of people worldwide still rely on herbal medicines. Herbal medicines can treat many conditions but are unregulated and carry risks of mislabeling, contamination, allergic reactions, and interactions with other drugs if not used properly. Education is important to make informed choices about herbal medicine use and safety.
