Nettle Leaf
Also known as: Urtica dioica leaf, stinging nettle leaf, Urticae folium
Nettle leaf is the dried aerial part of Urtica dioica, a nutrient-dense green used in traditional European herbalism and in modern seasonal and immune formulas. Its constituents differ from the root and include flavonoids, minerals, and chlorophyll. Leaf preparations appear in allergy-season blends alongside quercetin and in greens powders. Human trials are limited and mostly small; a meta-analysis has pooled studies in adults with type 2 diabetes, and evidence for other uses is preliminary.
Research summary
Flavonoids and other constituents studied for effects on inflammatory signaling; mechanisms in humans are not well established.
