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
Astringent ellagitannins, notably oenothein B, are associated with the plant's traditional anti-inflammatory and prostate-supportive reputation in the related Epilobium species.
Antioxidant polyphenols retained even after simulated digestion of the infusion.
Minor triterpenoid constituents contributing to the plant's bioactivity.
Alpha- and beta-bitter acids responsible for the characteristic bitterness and much of the sedative, GABA-A-receptor-active and antimicrobial activity.
Xanthohumol has antioxidant activity; 8-prenylnaringenin has notable phytoestrogenic activity, the basis of the mild oestrogenic caution.
Aromatic volatile oil contributing to the characteristic hop aroma.

Safety, Cautions & Contraindications
Generally considered safe at culinary and traditional tea-preparation doses. No major contraindications established for healthy adults in normal use. The young shoots and leaves are widely eaten as a spring vegetable in many cultures without adverse effects. At higher supplemental doses, limited human safety data are available; caution is advised during pregnancy and breastfeeding due to lack of robust safety studies. Tannin content may cause digestive upset or constrain iron absorption at very high doses. Rarely, contact dermatitis has been reported with topical preparations in sensitive individuals (Kozhevnikov and Kozhevnikova, 2021).
Duke (2002) includes fireweed (Epilobium angustifolium) as ++ with primarily experimental (score 1) evidence. It is used in European phytomedicine as an anti-inflammatory and astringent for gastrointestinal complaints. The related species Epilobium parviflorum has clinical support for benign prostatic hyperplasia (BPH), though data for E. angustifolium specifically is limited. Duke does not note major safety concerns at customary herbal doses (Duke, 2002).
Generally safe at therapeutic doses for short-term use. Hop preparations may enhance the sedative effects of alcohol, benzodiazepines, and other CNS depressants — avoid combination. Not recommended during pregnancy or breastfeeding. May have mild oestrogenic effects due to 8-prenylnaringenin — caution in hormone-sensitive conditions. Fresh hops can cause contact dermatitis in pickers.
Duke (2002) rates hops as +++ and provides clinical evidence (score 2) for sedative activity, consistent with Commission E approval for nervousness, unrest, and sleep disturbances. The primary sedative compound is 2-methyl-3-buten-2-ol, formed from humulone during storage. Duke notes that hop cones have estrogenic activity, explaining occupational menstrual irregularities reported among hop pickers. Dose: 0.5 g dried flower in tea before bed; often combined with valerian. Hops should not be used in depression, as its CNS-depressant effect may worsen depressive symptoms (Duke, 2002).

Botanical Description
Tall, upright perennial herb spreading by rhizomes, forming large colonies especially on disturbed or burned ground (hence 'fireweed'). The leaves are narrow, lance-shaped, and willow-like, arranged spirally up the stem. Bright pink-purple, four-petalled flowers are borne in a tall, tapering terminal spike (raceme), opening progressively from the base upward as the plant flowers through summer.[1]
Vigorous, twining perennial climbing vine with rough, hairy stems and deeply lobed, opposite leaves resembling grape leaves. The plant is dioecious; female plants bear the characteristic papery, cone-like flower clusters ('hops'), covered in yellow, resinous lupulin glands, that are the medicinal and brewing part.[1]
Habitat
A classic pioneer plant of disturbed, burned or cleared ground, forest clearings, roadsides and riverbanks; native across the temperate and boreal Northern Hemisphere (Europe, Asia, North America).[1]
Grows in hedgerows, woodland edges and damp thickets, climbing over other vegetation; native to Europe, Western Asia and North America, and widely cultivated for brewing.
Harvesting
Young shoots are gathered in spring while still tender (traditionally eaten like asparagus); leaves and flowers are picked through summer at flowering, with the leaf sometimes fermented for 'Ivan-chai' tea. Careful identification against the deadly false hellebore (Veratrum), which can share early-spring habitat, is essential when gathering young shoots.[1]
The female flower cones are picked in late summer once mature (when the lupulin glands are fully developed and sticky), then dried quickly to preserve the volatile oils and bitter resins.[1]
Traditional Uses
Fireweed has a long circumpolar tradition as a food plant (young shoots as a spring vegetable, fermented leaf as 'Ivan-chai' tea) and as a folk remedy for digestive complaints and topically as a poultice for wounds and skin inflammation, reflecting its astringent, anti-inflammatory character.[1]
Hop cones have a long European tradition as a calming, sedative herb for nervous tension, restlessness and insomnia, and as a bitter digestive tonic; the sedative reputation, historically noted among hop-pickers who became drowsy from handling the cones, is now linked to GABA-A receptor-active bitter resins.[1]
Preparations
Fresh or fermented, dried leaf infused in hot water as a traditional tea, valued both as a beverage and a mild digestive/anti-inflammatory remedy.
Dried flower cones infused in hot water as a herbal tea, 500-1000 mg in 150-200 ml, taken 30-60 minutes before bedtime per the EU herbal monograph. Educational reference only, not a prescription.
Tincture (1:5) of the dried cones, 1-2 ml up to three times daily per the EU herbal monograph. Educational reference only, not a prescription.
Concentrated extract standardised to xanthohumol/humulone content, studied for sleep-enhancing activity via GABA-A receptor modulation.
Dosage
The EU herbal monograph on Epilobium angustifolium L. and/or Epilobium parviflorum Schreb., herba - which covers this species under its Epilobium name - gives 1.5-2.0 g of the comminuted herb in 250 mL of boiling water as an infusion, twice daily, in adults and elderly; long-term use is possible. A doctor should be consulted if fever, spasms, blood in the urine, painful urination or urinary retention occur. Educational reference only, not a prescription.
The EU herbal monograph distinguishes two uses, in adolescents, adults and elderly. To aid sleep - 500-1000 mg of the comminuted flower in 150-200 mL of boiling water as an infusion, 30-60 minutes before bedtime. In mental stress - 500 mg in 150-200 mL as an infusion, up to 4 times daily. A 1:5 tincture at 1-2 mL up to 3 times daily is also listed. Educational reference only, not a prescription.
