Phytochemical Properties and Health Impacts of Urtica Dioica

Urtica dioica, commonly known as stinging nettle, is a herbaceous perennial distributed across temperate regions. Its traditional uses as food, fibre and medicine reflect a rich phytochemical profile, encompassing polyphenols (including flavonoids and phenolic acids), sterols, fatty acids, alkaloids, terpenoids, chlorophyll pigments, carotenoids, vitamins and an array of minerals. Concentrations of these compounds vary with plant part, developmental stage and environmental factors. Mechanistic studies attribute antioxidant, anti-inflammatory, antimicrobial, anti-diabetic and anticancer activities to nettle extracts, with specific molecules such as quercetin, caffeoyl derivatives and β-sitosterol frequently implicated. In addition to nutraceutical and functional-food applications, nettle shows promise in cosmetic and pharmaceutical formulations. Despite extensive preclinical data, standardisation of extraction methods and rigorous clinical evaluation remain priorities to translate traditional knowledge into evidence-based therapies.

Phytochemical Properties and Health Impacts of Urtica Dioica publication trend

The graph below shows the total number of articles in phytochemical properties and health impacts of urtica dioica across all publications each year (not limited to Nature Index journals).

Technical terms

Polyphenols: Plant-derived compounds with multiple phenolic groups, known for antioxidant and anti-inflammatory effects.

Flavonoids: A subclass of polyphenols characterised by a 15-carbon skeleton, contributing to free-radical scavenging.

Sterols: Lipid compounds related to cholesterol, implicated in membrane stability and modulation of inflammatory pathways.

Supercritical fluid extraction: A technique using fluids (often CO₂) above critical temperature and pressure to isolate bioactives with minimal solvent residues.

Antioxidant capacity: The ability of a substance to neutralise reactive oxygen species and prevent oxidative damage.
