Stinging Nettle, has a well-known reputation for its sting when the skin touches the hairs and bristles on the leaves and stems. The name Urtica comes from the Latin verb urere, meaning 'to burn’. Interestingly when the fine hairs on the Urtica plant come into contact with a painful area of the body they can actually cause a decrease in the original pain! Alfred Vogel was one who advocated this treatment to a number of his patients. Today A.Vogel is kinder and the aerial parts of Urtica plants are carefully harvested and manufactured twice yearly into a tincture.
