 Urtica dioica (Urticaceae)
STINGING NETTLE, COMMON NETTLE
The common nettle is used by
herbalists to treat skin disease and rheumatism. The sting is inactivated by
drying or heating. Homeopaths give U. urens for rheumatism, burns,
and rashes.
The Romans used to flail their rheumatic joints with nettles and rub the leaves on
their bodies to warm them up in British winters. The sting, which is due to ammonia in special hairs on the leaves, stimulates blood circulation.
Drying or heating the leaves inactivates this stinging chemical. Nettle also contains vitamin C and iron, and increases the absorption of the latter.
A native of Europe and Asia but naturalized throughout the world, it has heart-shaped leaves with normal and stinging hairs, and flowers throughout summer.
