There are thirty types of nettles worldwide and there are two types found in the U.S., stinging nettle and California nettle. The stinging nettle plant plays a role in traditional Native American herbal medicine as well as in ceremonies. In the Pacific Northwest, for example, men rubbed nettles on their bodies in fishing, whaling, and seal hunting rituals. Stinging nettles sometimes appear in Native American legends as comic relief, where a trickster ends up tumbling into nettles. Stinging nettle is often associated with the coyote, and they have a long history as a source for traditional medicine, food, tea, and even textiles.
About Stinging Nettles
Urtica dioica is also known as stinging nettle or common nettle. It is a herbaceous perennial flowering plant that was originally native to Europe but is now found all over the world. Stinging nettle grows to the height of three feet. Its dull green stem and leaves are covered with stinging hairs that pierce the skin and emit an acrid fluid that causes pain when touched. The stinging hairs are called trichomes that act like hypodermic needles that inject histamine, acetylcholine, serotonin, and formic acid that produce a stinging sensation on contact. The leaves are slightly heart-shaped and have a strongly serrated margin. They bear tiny greenish - yellow-colored flowers that can usually be seen June - September before forming seeds. This plant spreads by rhizomes as well as by seed. Given moist rich soil it thrives in sunny meadows, near woodland brooks and marshes, and along roadside ditches.
