Key Constituents
The principal immunomodulating constituents, forming the basis of PSK/PSP extracts.
Protein-bound polysaccharide complex studied extensively as an adjunct immunotherapy.
Minor antioxidant 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.

Safety, Cautions & Contraindications
Generally very safe and well tolerated. Rare cases of digestive upset or allergic reaction. No significant known drug interactions at normal doses. The PSK pharmaceutical form is used safely alongside standard cancer treatments. Suitable for most adults.
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
Bracket fungus (not a true plant) forming thin, tough, fan-shaped, overlapping shelves on dead or decaying hardwood, with a velvety, concentrically zoned upper surface in bands of brown, tan, cream, blue-grey and rust, and a white, minutely pored underside.
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 on dead, dying or fallen hardwood logs, stumps and branches in woodlands worldwide, including Europe, Asia and North America.
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
Fresh brackets are harvested by cutting from the wood; for medicinal use the tough fruiting body is typically dried and then decocted (simmered) for a long time, or extracted, since the beneficial polysaccharides are not well-extracted by simple infusion.
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
Turkey tail has a long history of use in traditional Chinese medicine (as yun zhi) and is one of the most researched medicinal mushrooms, with standardized polysaccharide-K (PSK) and polysaccharopeptide (PSP) extracts used clinically in Japan and China alongside conventional cancer treatment to support immune function.[11, 12, 13]
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
Dried fruiting body simmered in water for an extended period (often 1-2 hours) to extract the beta-glucan polysaccharides, then strained.
Standardized polysaccharide-K (PSK) or polysaccharopeptide (PSP) extract, the pharmaceutical-grade forms used in clinical research.
Dosage
Clinical research on PSK commonly uses around 3 g daily in divided doses. 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.
