Sétif Nettle Extracts Show Strong Antioxidant, Anti-inflammatory Power
A recent study led by Algerian researchers, including teams from Abbes Laghrour University of Khenchela and Ferhat Abbas University of Sétif 1, has provided significant scientific validation for the traditional medicinal uses of stinging nettle (Urtica dioica). The research focused on nettle harvested from the semi-arid Bir Hadada region in eastern Algeria, meticulously examining various extracts from the plant's aerial parts. The comprehensive laboratory characterization revealed that these extracts possess potent antioxidant and anti-inflammatory properties, underscoring the plant's value in a scientific context.
The study, published in the journal Plant Biosystems, systematically explored how different extraction methods influence the phytochemical composition and biological activity of the nettle. Researchers prepared five distinct extracts, including a traditional decoction mimicking common herbal practices, and assessed their antioxidant capacity through multiple assays. Notably, the methanolic extract demonstrated significant anti-inflammatory effects, inhibiting heat-induced protein denaturation by 90% in vitro and reducing inflammation in living systems by up to 89.06%. The findings suggest that the semi-arid climate of Sétif, characterized by environmental stresses, contributes to higher yields of beneficial phenolic secondary metabolites in Algerian nettle, comparing favorably with species grown in more temperate regions.
This pioneering Algerian research not only provides a compelling proof of concept for the therapeutic potential of Urtica dioica but also establishes a valuable methodological template for evaluating other traditional plants indigenous to marginal climates. The in vivo experiments adhered to ethical guidelines set by the Algerian Association of Sciences in Animal Experimentation, with mice sourced from the Pasteur Institute of Algeria, showcasing adherence to modern scientific standards. The study offers practical insights for future research and formulations, further solidifying Algeria's contribution to scientific understanding of natural medicinal resources.
