Nettles are members of the genus Urtica in the family Urticaceae.
The most prominent member of the genus is the Stinging nettle Urtica dioica, native to Europe, Asia, and North America. The genus also contains a number of other species with similar properties, listed below. However, a large number of species names that will be encountered in this genus in the older literature are now recognised as synonyms of Urtica dioica. Some of their names survive as subspecies names.
All the species listed below share the property of having stinging hairs, and can be expected to have very similar medicinal uses to the stinging nettle.
The family Urticaceae also contains some other plants called nettles that are not members of the genus Urtica. These include the Wood nettle, Laportea canadensis, found in eastern North America from Nova Scotia to Florida, and the False nettle, Boehmeria cylindrica, found in most of the United States east of the Rockies. As its name implies, the false nettle does not sting.
Species in the genus Urtica, and their primary natural ranges, include:
- Urtica angustifolia; China, Japan, Korea
- Urtica cannabina; Western Asia from Siberia to Iran.
- Stinging nettle, Urtica diotica; Europe, Asia, North America
- Urtica hyperborea; Himalayas from Pakistan to Bhutan, Mongolia and Tibet, high altitudes.
- Scrub nettle, Urtica incisa; Australia

Economic Uses
Nettle stems are a popular raw material used in small-scale papermaking.The tops of growing nettles are a popular cooked green in many areas, and are exceptionally high in protein. Some cooks throw away a first water to get rid of the formic acid, while others retain the water and cook the nettles straight. Nettle tops are sold in some farmers' markets and natural food stores.
