Nettle, or stinging nettle, is a shrub that comes from northern Europe and Asia. Its scientific name is Urtica dioica. The plant boasts pretty, heart-shaped leaves and yellow or pink flowers, but the stem is covered in tiny, stiff hairs that release stinging chemicals when touched.

The leaves, stem, or root from the nettle plant can be crushed and made into powders, tinctures, creams, teas, and more. While people have used it for centuries as an herbal medicine, modern research also supports many of the potential health benefits of nettle and nettle tea.
