Urtica dioica, known as common
nettle, is typically called stinging nettle, because chemicals in the
hairs or spines on the leaves and stems cause skin irritation and pain
when touched. People have used nettle for medicinal purposes since
ancient times, according to the University of Michigan Health System.
Nettle root is available in liquid extract, dried extract in capsule
form and as a tea. Consult with a qualified health care practitioner
before beginning any herbal therapy, particularly if you have a serious
health condition.
