Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Contribute to the antioxidant and anti-inflammatory action.
Thought to underlie the root's traditional use for BPH-related urinary symptoms.
The irritant compounds responsible for the fresh plant's sting; destroyed by cooking, drying or freeze-drying.
Pharmacological Actions
Adaptogen for stress and anxiety (improves stress scores and well-being in trials)
Cognitive support - a placebo-controlled study in healthy adults found improved reaction time and accuracy and shorter P300 latency

Safety, Cautions & Contraindications
Generally well tolerated; mild nausea has been reported. Its blood-sugar-lowering effect means caution alongside antidiabetic medicines.
Fresh plant causes stinging skin reaction (formic acid, histamine). Once cooked, dried, or freeze-dried, this is eliminated. Root tincture may interact with diuretics, antihypertensives, and antidiabetic drugs. Generally very safe in culinary and standard medicinal use. Avoid very high doses in pregnancy.
Duke (2002) rates stinging nettle as +++ and provides clinical evidence (score 2) for antiprostatitic activity (BPH — benign prostatic hyperplasia), consistent with Commission E approval for irritative urination symptoms associated with BPH. Dose: 4–6 g dried herb daily or 600–1200 mg root extract. The root preparations are used for BPH while leaf preparations are used for antiallergic and anti-inflammatory purposes. Duke also notes experimental antiarthritic and analgesic activity. Generally safe; the most common adverse effect is mild gastrointestinal upset (Duke, 2002).

Botanical Description
Aromatic annual or short-lived perennial subshrub (Lamiaceae), 30-75 cm tall, with erect, much-branched, hairy stems often tinged purple. Leaves are opposite, ovate-oblong with a toothed margin, and release a strong, clove-like (eugenol) scent when crushed. Small purplish-pink, two-lipped flowers are borne in elongated terminal racemes. The plant is held sacred in Hindu tradition (Tulsi).[11]
Tall, upright perennial herb with square stems and opposite, deeply toothed, heart-shaped to lance-shaped leaves covered in fine stinging hairs that inject formic acid and histamine on contact. Tiny, greenish, petal-less flowers hang in branched, drooping clusters from the leaf axils.[11]
Habitat
Native to the Indian subcontinent and tropical Asia, now cultivated and naturalised throughout the tropics and subtropics worldwide; commonly grown in home gardens and temple courtyards as well as cultivated as a medicinal and aromatic crop.[12]
Grows abundantly on nitrogen-rich waste ground, hedgerows, riverbanks, woodland edges and disturbed soil; native to Europe, Asia, North Africa and North America and now found nearly worldwide.[11]
Harvesting
Leaves are harvested year-round from actively growing plants, ideally picked once morning dew has dried; whole flowering tops are also gathered.
Young leaves and tops are gathered in spring before flowering, when stinging is least severe and nutrient content highest, using gloves; the root is dug in autumn or spring; seed is collected when ripe in late summer. Cooking, drying or freeze-drying neutralises the sting.[11]
Traditional Uses
Tulsi is one of the most revered plants in Ayurvedic medicine, traditionally used as an adaptogen for stress, a remedy for respiratory complaints (colds, cough, asthma), and a general immune tonic. Modern clinical trials support adaptogenic/anti-stress, blood-sugar-lowering and immunomodulatory effects consistent with these traditional uses.[3, 12]
Nettle leaf has a long tradition as a nutritive spring tonic, diuretic and anti-inflammatory remedy for joint pain and rheumatism, while the root has a well-documented traditional and modern use for the irritative urinary symptoms of benign prostatic hyperplasia; the seed has a lighter tradition as a kidney tonic.[11, 12, 13]
Preparations
Dosage
Clinical trials for stress and mood have used standardised dry-extract capsules taken over several weeks; dosing varies by product concentration, so follow the manufacturer's guidance. Educational reference only, not a prescription.
The WHO monograph on Folium Ocimi Sancti gives a daily dosage of 6-12 g of the crude drug as a decoction. This is a whole-day total for the fresh or dried leaf, notably higher than the 1-2 g per cup often quoted in popular sources. Educational reference only, not a prescription.
The EU herbal monograph on nettle leaf gives 2-4 g as a single dose for herbal tea, 3-6 times daily, for a daily dose equivalent to 8-12 g, in adolescents, adults and elderly; a 1:5 liquid extract at 30-40 drops 3-4 times daily and several dry extracts are also listed. Not to be used for more than 4 weeks, and not recommended under 12 years. Educational reference only, not a prescription.
Traditional and Commission E sources suggest around 600-1200 mg root extract daily for BPH-related urinary symptoms. Educational reference only, not a prescription.
