Etymology
The term Urtica dioica is derived from the Latin urtica meaning "nettle", and dioica meaning "two houses", referring to the plant's separate male and female flowers.
Description
Urtica dioica is a dioecious, herbaceous, perennial plant, 1 to 2 m (3 to 7 ft) tall in the summer and dying down to the ground in winter. It has widely spreading rhizomes and stolons, which are bright yellow, as are the roots. The soft, green leaves are 3 to 15 cm (1 to 6 in) long and are borne oppositely on an erect, wiry, green stem.
Medical Uses
Urtica dioica has a long history of use as a medicinal plant and is currently used in herbal medicine for a variety of ailments. The leaves and young stems of this herbaceous plant are fitted with stinging hairs tipped with formic acid and other irritants. If touched, these needle-like hairs inject the stinging acid into the skin, triggering a burning, tingling sensation and an itchy rash. Despite its stinging properties, when processed and used medicinally, Urtica dioica can have several health benefits.
