Stinging nettle (Urtica dioica) is a flowering plant with leaves and stems covered in bristly hairs that cause a painful “stinging” sensation when touched. The hairs release chemicals, including histamine, as part of the plant’s natural defense mechanisms.
Throughout history, stinging nettle has been used for various purposes. Native Americans used the plant’s fibers to make rope, and boiled the roots and leaves for food. It was also used as a folk remedy for joint health and seasonal challenges.
