Spices are flavorings, often of tropical origin, that are dried. Most spices come from plant fruits, as is the case for mace, nutmeg, black pepper, and cardamom. Cinnamon comes from the bark of a shrubby tree, and ginger comes from the underground rhizome of a plant. Herbs, in the culinary sense, are leaves of plants that can be used either fresh or dried to season food. In the botanical sense, an herb is any plant that does not have woody perennial stems like a tree or shrub.
