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
The principal bioactive constituents, responsible for most of the mushroom's immunomodulatory and anticancer activity.
Contribute to immunomodulatory activity alongside the pure beta-glucans.
Contribute to the antioxidant activity of the fruiting body.
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.

Safety, Cautions & Contraindications
Generally very safe as a food. Rare cases of occupational asthma and allergy reported among people working with mushroom cultivation. Safe for culinary use without significant known interactions.
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
Wood-decay fungus (not a true plant, Pleurotaceae) that grows in shelf-like, overlapping clusters on dead or dying hardwood trees and stumps. Fan- or oyster-shell-shaped caps, 5-25 cm across, are usually grey, tan or brown (occasionally pale or white), with white gills running down a short, off-centre stem. The mycelium is a fine white network that colonises and decomposes the wood substrate before fruiting.
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
Grows naturally on dead or dying broadleaf (hardwood) trees - beech, oak, poplar and others - in temperate forests worldwide; widely cultivated commercially on straw, sawdust and other lignocellulosic substrates.
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
Wild fruiting bodies are picked as the caps mature but before they become tough or insect-damaged; cultivated mushrooms are harvested from substrate blocks or bags once the caps have expanded but before releasing significant spore load. Never forage a white shelf-fungus from wood without confirming the host tree, since the fatal Angel Wing look-alike is specific to conifer (softwood) wood.[14]
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
Oyster mushroom is a widely eaten culinary mushroom with a growing modern reputation as a medicinal fungus, valued for immune support and general wellbeing. Contemporary research on its beta-glucan polysaccharides supports immunomodulatory, antioxidant, anticancer and cardiometabolic activity.[1, 5]
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
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.
