Herbs are any plants used for food, flavouring, medicine, or perfume. Culinary use typically distinguishes herbs from spices. Herbs refer to the leafy green parts of a plant (either fresh or dried), while a “spice” is a product from another part of the plant (usually dried), including seeds, berries, bark, roots and fruits.
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, resin, root bark, inner bark, berries and sometimes the pericarp or other portions of the plant.
