Nettle leaf: It stings…and heals


Botanical Urtica dioica, commonly known as nettle leaf, common nettle, or stinging nettle, is an herbaceous, perennial flowering plant with coarsely serrated leaves 1 to 6 inches (3 to 15 cm) long. It grows abundantly in North America, Europe and Asia, usually in rural habitats where moist soils are prevalent. All parts of the plant—stems, leaves, flowers, seeds, and roots—offer numerous health benefits ranging from arthritis relief to more luxurious hair. The leaves can be prepared in a variety of ways to provide a nutritious food source. The fibers within the core of nettle stems, similar to flax (linen) have been used for centuries to make clothing and other textiles. Often reaching heights of 3 to 7 feet (1 to 2 m), stinging nettle gets its name from the stinging hairs on its stems and leaves called trichomes. The hairs inject histamines, acetylcholine—a common neurotransmitter found in many organisms, including humans—and formic acid. These chemicals produce a sharp stinging sensation when they come in contact with animals and humans.

Medicinal Uses

Stinging nettle is widely considered to be a safe treatment option for many chronic disorders.  Its gentle, stimulating effects help to cleanse the blood and eliminate wastes through the kidneys. It is rich in vitamins A and C, and in minerals calcium, iron, potassium, and magnesium. When soaked in water or cooked, the stinging properties of nettle are no longer present. The leaves, stems, and roots can be infused to make a tea. When taken daily, the tea is purported to have beneficial effects for many conditions including:
