    plant name


    1. stinging nettle , great nettle
    2. Stinging nettle , little nettle , shrike

    International Latin denomination


    1. Urtica dioica L.
    2. Urtica urens L.

    botanical family




    Description and habitat


    • Well-known, invasive perennial herb, 60-120 cm tall, with pointed opposite leaves, covered with stinging, bristly hairs. The tip of these hard, conical bristles break upon contact and inject the stinging substances contained therein
    • Nettles are cosmopolitan “weeds”
    • Nitrophilic and ruderal, they are very common around houses, in rubble and ditches


    History and tradition


    • Considered a panacea in the Middle Ages, especially for hemorrhages
    • Do not confuse them with the White nettle or Lamiaceae white deadnettle ( Lamium album L.)
    • They are very "animic" plants because they synthesize specific substances of the animal kingdom (histamine, serotonin, acetylcholine)


    Parts used


    • Yellowish colored leaves and roots (with long branching rhizomes)


    Dosage forms available



    Usual dosages


    • Leaf tea: classic infusion, 5 grams of leaves three times a day
    • Root tea in decoction: mix 1.5 grams of coarsely powdered drug with cold water, heat and keep boiling for 1 minute, infuse 10 minutes, strain




    Main components of the plant


    Leaves  :

    Roots  :


    Main components of buds or young shoots


    Main components of essential oil




    Plant properties


    Sheet properties  :

    • Diuretic, removes urea, uric acid and chlorides [1] , [2] , antigout, causes a moderate decrease in blood pressure
    • "depurative", cholagogue, would stimulate the enzymatic production of the pancreas
    • Anti-rheumatic (derivatives of caffeic acid inhibit the arachidonic acid cascade in vitro ), preventive of arteriosclerosis, anti-allergic (inhibition of the PAF of neutrophils Platelet Activating Factor), caffeoylmalic acid would be one of the antirheumatic active ingredients, as an inhibitor of cyclooxygenase biosynthesis, effect similar to 200 mg/day of diclofenac [3] , leaf extracts inhibit the biosynthesis of enzymes of the arachidonic cascade, (cyclo-oxygenases COX-1 and COX-2), block the biosynthesis of prostaglandins and thromboxane [4]
    • Anti-inflammatory [5] , analgesic [6] , [7]
    • Antimicrobial, anti-ulcer [8]
    • Anti-anemic (stimulates hematopoiesis), formerly industrial source of chlorophyll (even if it does not contain more than other leaves), remineralizing
    • Hepatoprotective and antioxidant [9]
    • Hypoglycemic by inhibiting the intestinal absorption of glucose [10] , and by stimulating insulin secretion by the islets of Langerhans [11]
    • Cardiovascular protector [12]
    • Anti-allergic [13] , with anti-inflammatory effect inhibition of prostaglandin synthesis by inhibition of cyclooxygenase-1 (COX-1), Cyclooxygenase-2 (COX-2), and HPGDS (Hematopoietic Prostaglandin D(2 ) synthase) [14]
    • Immuno-stimulant by activity on the function of neutrophils ( flavonoids ) [15]
    • Cancer prevention ( phenolic acids ) [16]
    • Antiviral potential by affinity with the ACE-2 receptor [17]

    Root properties  :

    • Astringent due to tannin content and antiphlogistic due to lectins ( UDA ) and polysaccharides
    • Effective in benign prostatic hyperplasia [18]
    • A fatty acid is an aromatase inhibitor responsible for the conversion of testosterone to 17-beta-estradiol
    • Lignans ( secoisolariciresinol ) and octadecanoic acids would prevent SHBG (sex hormone binding globulin) from binding to its receptor [19]
    • Antiproliferative activity of hydro-alcoholic extracts on prostate tissue ( UDA and polysaccharides ) [20]
    • Likely inhibition of testosterone-5-alpha-reductase (unproven)
    • Inhibition of NF-kappaB activation [21]
    • Hydroalcoholic extracts improve sperm count and motility and inhibit nicotine -induced adverse effects on sperm quality [22]
    • Clinical observations show a decrease in voiding frequency, post-void residual, prostate volume, and hormonal levels with extract doses of 600 to 1200 mg per day, and over periods of 3 to 6 months.
    • Hypotensive by vasorelaxation effect mediated by the release of endothelial nitric oxide (NO), by the opening of potassium channels, and by a negative inotropic effect [23] , causes aortic vasoconstriction due to the activation of alpha1- receptors adrenergic [24] and by a natriuretic action [25]
    • Inhibition of SARS-CoV-1 replication by a lectin , ( Urtica dioica agglutinin ) [26]


    Bud properties


    Properties of essential oil




    Indications of the whole plant (phytotherapy)


    Leaves  :

    • Moderate acne, hyperseborrhoea
    • Painful joints (it is not a powerful anti-inflammatory, it is mainly used for drainage in rheumatological conditions)
    • Hyperuricaemia
    • Remineralization, osteoporosis
    • Mainly iron deficiency anemias
    • Asthenia
    • Hair loss: rubefacient properties, activation of hair metabolism

    Roots  :

    • Voiding disorders of prostate adenomas in stages I and II, and logically fibroids (mainly antiproliferative and much less hormonal action)
    • To be tried in male acne (logical indication)
    • Other: inflammation of the urinary tract, prevention of nephrolithiasis


    Indications of the bud (gemmotherapy)


    Specific indications of essential oil (aromatherapy)


    Known or suspected mode of action


    Leaf  :

    • Inhibition of the arachidonic acid cascade, inhibition of neutrophil PAF (Platelet Activating Factor)

    Root  :

    • Lectins (proteins whose name comes from the Latin “legere” = to read, to choose, “to select" [ 29] ) bind reversibly to osidic receptors on cell membranes
    • Inhibition of aromatase responsible for the conversion of testosterone to 17-beta-estradiol
    • Inhibition of SHBG (sex hormone binding globulin) binding to its receptor
    • Antiproliferative activity on prostate tissue
    • Likely inhibition of testosterone-5-alpha-reductase (unproven)


    Usual formulations


    Gardeners know the antifungal properties of fermented nettle juice or manure on their vegetables


    Manufacture of nettle manure: macerate in 10 liters of water (preferably rain) 1.5 kg of young chopped nettle leaves (not gone to seed), filter the maceration obtained (bad smell, it is normal) after a fortnight

    Use :

    Dilution of 2 liters of manure for 10 liters of water (preferably with rainwater)

    • As a spray on the ground against cryptogamic diseases such as mildew

    • Growth activator (rich in mineral salts)

    Dilution of 1 liter of manure for 10 liters of water:

    • Insecticide (aphids) in fine spray on the leaves

    Without dilution:

    • Compost activator




    1. French Pharmacopoeia list A (aerial part, underground part of Urtica dioica )
    2. French Pharmacopoeia list A (root, aerial part of Urtica urens )


    Possible side effects and precautions for use


    • Drug interactions are described, but with seed extracts [30]
