Overview

Nettle has been used worldwide for centuries in a variety of countries and cultures. It has been eaten as a wild food plant, applied topically to the skin, and drunk as a mineral rich tea for its diuretic and soothing effects on the urinary tract. It was used extensively for its fibers, similar to flax and hemp, and was woven into cloth.3,4,5 Nettle fibers were considered to be high quality and comparable to flax or hemp in Northern Europe.

Botany

There are around 50 species of Urtica worldwide 4 all members of the Urticaceae family. Urtica is derived from Latin verb urere, which means "to burn," and is named such due to its stinging (urticate) hairs. The species name dioica comes from the botanical term dioecious meaning that a species has either male or female flowers. The species most commonly found in North America is U. dioica ssp. gracilis which has 6 varieties, 5 of which have trichomes (stinging hairs). 7 Essentially there are a few species (namely U.dioica and U. urens) and subspecies that are similar and can be used interchangeably.6,7,8,9 Both of these species are native to Eurasia and Africa and are common weeds which have become naturalized in North and South America and Australia.10 This perennial plant loves moist areas and grows along streams and marshes from around sea level to altitudes of 10,000 feet.9 It can grow from 2 to 6 feet tall, has ovate serrated leaves, heart-shaped at the base, square stems, and has long clusters of greenish flowers.10,11 The entire plant is covered with stinging hairs that come off when touched and can cause contact dermatitis.11

Cultivation And Harvesting

Prefers part shade or sun and moist fertile soil. Grows well in all zones. 2 It is best to collect leaves just before flowering 4,12 or, at first flowering depending on the geographic area in which you are harvesting.9 Although in some regions nettles can be harvested most anytime throughout the year.13 And, it is definitely best to wear gloves!!

The seeds can be collected in the late summer by cutting off the flowering tops and hanging them upside down allowing the seed to fall off as they dry.9

History And Folklore

Nettles has been employed as a spiritual talisman in which it was sprinkled around the house to ward off evil or carried in a sachet in order to "remove a curse and send it back".16 Nettles have been consumed by a variety of cultures. The spring shoots (leaf tips) were boiled as an edible vegetable like spinach 4,9,12 Rosemary Gladstar suggests adding lemon, olive oil, and feta cheese to steamed young nettle tops.12 Further, various native American cultures used an assortment of nettle preparations for numerous illnesses and in pregnancy and childbirth.17

Various sources suggest using the plant to stimulate hair growth.13,18,20 According to the late herbalist Michael Moore, the seed contains trace amounts of formic acid that can be used topically on the scalp to stimulate hair growth.9

Herbal Miscellany

Nettle fiber was used in Europe in the early 1900's for cloth to make stockings, tarps and army clothing3. It was estimated that it took roughly 90 lbs of fiber to make one shirt. Overalls from a captured German soldier revealed the cloth to be made of 85% nettle and 15% ramie (Boehmeria nivea), which is from the nettle's tropical cousin, and is one of the oldest continually cultivated fiber crops.20 Ramie was a principal component in the cloth used to wrap mummies in ancient Egypt and is currently cultivated in China, India, and SE Asia.
