An herb farm is usually a farm where herbs are grown for market sale.
 There is a case for the use of a small farm being dedicated to herb farming as the smaller farm is more efficient in terms of manpower usage and value of the crops on a per acre basis.
 In addition, the market for herbs is not as large as the more commercial crops, providing the justification for the small-scale herb farm.
 Herbs may be for culinary, medicinal or aromatic use, and sold fresh-cut or dried.
 Herbs may also be grown for their essential oils or as raw material for making herbal products.
 Many businesses calling themselves an herb farm sell potted herb plants for home gardens.
 Some herb farms also have gift shops, classes, and sometimes offer food for sale.
 In the United States, some herb farms belong to trade associations. Elaeagnus tonkinensis
