Herbs are plants or plant parts prized for their medicinal, savory, or aromatic qualities.

In general use, herbs are any plants used for flavoring, food, medicine, or perfume. Culinary use typically distinguishes herbs as referring to the leafy green parts of a plant (either fresh or dried), from a “spice”, a product from another part of the plant (usually dried), including seeds, berries, bark, roots, and fruits.

In American botanical English, the term “herb” is also used as an abbreviation of “herbaceous plant”.
