Urtica spp.: Ordinary Plants with Extraordinary Properties - PMC

The Nugget

Nettles (Urtica spp.) are not just ordinary pesky weeds; they possess extraordinary properties beneficial for food preservation, traditional medicine, and as a functional food or dietary supplement. Their broad applications in the food and pharmaceutical industries are due to their rich content of biologically active compounds such as terpenoids, carotenoids, fatty acids, amino acids, chlorophyll, vitamins, tannins, carbohydrates, sterols, polysaccharides, isolectins, and minerals, showcasing significant antimicrobial activity against both Gram-positive and Gram-negative bacteria.

Key quotes

"Despite these benefits, the nettle is still an underestimated plant source."
"Nettles show noticeable activity against both Gram-positive and Gram-negative bacteria."
"For fiber production, stinging nettles should be harvested when the seeds are mature or when the stalks reach 80% of the aboveground biomass, from the second year of planting."
"Nettles can improve soils over-fertilized with nitrogen and phosphate."
"Nettle leaves contain particularly large amounts of the metals selenium, zinc, iron and magnesium."

Study of Urtica spp. involves examining the plant's habitat, phytochemical composition, antimicrobial activities, and applications in traditional and modern medicine, as well as food and feed applications.
Methodology includes qualitative and quantitative analysis of the nettle's chemical components, and testing its extracts against a spectrum of bacteria for antimicrobial activity.
No specific doses or frequencies mentioned for human or animal consumption; variations exist based on the part of the plant being used (leaves, roots, seeds).
The study encompasses observational and experimental research backed by historical use in traditional medicine, rather than being a randomized controlled trial. It's a comprehensive review, indicating a wide-ranging examination but lacks direct experimental protocols for replication.

Urtica spp.: Genus of flowering plants known as nettles, which includes several species, prominently the stinging nettle (Urtica dioica L.).
Phytochemical: Chemicals produced by plants often used in medicines, foods, and other applications due to their health-promoting properties.
Biologically active compounds: Natural substances in plants that can affect biological processes in organisms, contributing to health benefits or therapeutic effects.
Terpenoids and carotenoids: Classes of phytochemicals known for their antioxidant properties.
Antimicrobial activity: The ability to prevent the growth of or to kill microorganisms, including bacteria and fungi.

Nettles have antimicrobial properties effective against a range of bacteria, making them suitable for applications in natural preservatives in food and as potential ingredients in pharmaceutical formulations.
Their rich phytochemical composition contributes to various health benefits, including anti-inflammatory, analgesic, and diuretic effects.

Beyond medicinal uses, nettles offer significant nutritional value when used in food, contributing vitamins, minerals, and proteins; they're utilized in soups, teas, and as a spinach alternative.
In agriculture, nettles can improve soil quality, serve as an animal feed supplement to enhance health and productivity, and their fibers have historical use in textiles.
