"Clove is a plant grown in parts of Asia and South America. People use the oils, dried flower buds, leaves, and stems to make medicine. Clove is most commonly applied directly to the gums for toothache, pain control during dental work, and other dental-related issues. But there is limited scientific research to support these and other uses. In foods and beverages, clove is used as a flavoring. In manufacturing, clove is used in toothpaste, soaps, cosmetics, perfumes, and cigarettes. Clove cigarettes, also called kreteks, generally contain 60% to 80% tobacco and 20% to 40% ground clove."
