Herbs are the plants used for food, flavoring, medicine, or fragrances for their savory or aromatic properties. Culinary use typically distinguishes herbs from spices. Herbs refer to the leafy green or flowering parts of a plant (either fresh or dried), while spices are produced from other parts of the plant (usually dried), including seeds, berries, bark, roots, and fruits. In the botanical word “herb” is also used as a synonym of “herbaceous plant”.
Herbs have a variety of uses including culinary, medicinal, and in some cases, spiritual. General usage of the term “herb” differs between culinary herbs and medicinal herbs. In medicinal or spiritual use any of the parts of the plant might be considered “herbs”, including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin, and pericarp.
