In modern European and American culture, the medicinal substances derived from natural sources used in traditional medicine are commonly called as “herbs,” “herbal medicines,” or “botanical medicines.” In the old European and American culture, such substances had been called as “crude drugs,” and they had used the medicines derived from not only plants (herbs) but also animal tissues and minerals. However, after the active chemical ingredients had been isolated from these medicines, the custom using medicines derived from animals and minerals had been disappeared, and they are using only the medicines derived from plants in traditional or alternative medicine.
