The practice of using herbal supplements dates back thousands of years. Today, the use of herbal supplements is popular among worldwide consumers. Herbal products are made from botanicals, or plants, that are used to treat diseases and conditions or to maintain good health are called herbals, botanical products, or phytomedicines. A product made from plants and used solely for internal use is called an herbal supplement.
Many prescription drugs and over-the-counter medicines are also made from plant products, but these products contain only purified ingredients and are regulated by the FDA. Herbal supplements may contain entire plants or plant parts.
