Urtica dioica L


Green nettle is a herbaceous, vivacious plant of up to 1 m in height. It’s provided with stinging hairs. The stems are erect and quadrangular. Leaves are oval-shaped, toothed and pointy. Flowers are small, green and not very showy, unisexual displaced in racemes. Fruit is a dry achene.

The plant has rigid hairs that sting and are painful to the touch. These stinging hairs are hollow and have resistant walls and hold inside a burning substance that become harmless when it gets dry or if the soak injured part in water as hot as can be borne without damage. As it can be identified by touch, in some languages it is known as ‘herb of the blind’.

It is a weed of a cosmopolitan distribution. Green nettle prefers humid soils rich in organic matter. It blooms in spring and summer.
