By Ginger Hultin, MS RDN CSO

But next time you’re out, think about bringing some gloves to collect them – nettles are a nutrition powerhouse! Stinging nettles are one of nature’s many superfoods so read on to learn about the nutritional and healing benefits of this medicinal plant.

Growing naturally in many areas of the world, there is good reason that nettles have been used medicinally in Africa, Asia, Europe and America for centuries. Chemical compounds have been identified in the roots, leaves and hairs of the stinging nettle plant and have been linked to antioxidant, anti-inflammatory, anti-viral, blood sugar and blood pressure lowering effects. When cooked, nettles test rich in calcium, magnesium, iron, manganese, zinc, copper, and chromium. Fresh and dried nettles also contain antioxidants such as carotenoids chlorophyll and beta-carotene as well as flavonols and tannins.

They are also used in powdered or supplement form for a variety of therapeutic treatments.

Nettles are used medicinally for a many of health conditions but are perhaps best known for treating seasonal allergies. Compounds have been found in nettles that help combat the inflammation and reactivity of allergy sufferers. For example, composites in nettles appear to inhibit inflammatory pathways and also act against the histamine receptors which are responsible for allergy signs and symptoms.

Nettles are also used to treat bladder problems including enlarged prostate, irritable bladder and urinary tract infections. A specific compound in nettles, enzyme 5-alpha reductase, is associated with aiding in prostate support though research is still inconclusive on its effectiveness. Nettles, particularly extracts of the root, are also used for joint problems including osteoarthritis. The mechanism may be linked to the anti-inflammatory potential of the plant.
