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
Characteristic Epilobium polyphenols underlying the anti-inflammatory and prostate activity; a genus review identifies oenothein B as the dominant constituent and likely driver of the antimicrobial, anti-inflammatory, anti-proliferative and antioxidant effects.
Antioxidant constituents.
Sterols associated with benign prostatic hyperplasia support.
Chlorogenic, cryptochlorogenic and dicaffeoylquinic acids and caffeoylhydrocitric acid (antioxidant).
C-glycosidic flavones such as isovitexin and related flavonoids.
Saponin glycosides (knautiosides) characteristic of the plant and the Caprifoliaceae family.
Pharmacological Actions
Traditional 'blood purifier' (depurative) for skin complaints; the classic use of field scabious.
Knautia and related Caprifoliaceae extracts inhibit inflammatory mediators (COX/LOX).

Safety, Cautions & Contraindications
Lower urinary tract / prostate symptoms must be medically assessed first to exclude prostate cancer; willowherb is a supportive measure, not a substitute for diagnosis and treatment.
Well tolerated over three months in clinical use; longer-term safety data are limited.
Very little is known about the safety of field scabious and there are no clinical data; avoid medicinal doses in pregnancy and breastfeeding and use only modest amounts.
Most pharmacological data come from closely related Caprifoliaceae (genus Knautia, Scabiosa, Dipsacus) rather than Knautia arvensis itself; apply to field scabious with caution.

Botanical Description
Slender, softly hairy perennial herb with narrow, lance-shaped leaves and small, four-petalled, pale pink to lilac flowers with a notched tip, borne singly in the upper leaf axils. After flowering, long, narrow seed pods split to release cottony-tufted seeds, typical of the willowherb genus.[13]
A hairy perennial herb of the honeysuckle family (formerly Dipsacaceae), 25-100 cm tall, growing from a stout rootstock. The stems are roughly hairy and bear opposite leaves that are variable - the lower ones often lyre-shaped or pinnately lobed, the upper deeply cut. The flowers are massed into flat, domed pincushion heads about 3-4 cm across, lilac to bluish-violet, with the outer florets enlarged; the heads are carried on long stalks and, unlike true scabious (Scabiosa), the receptacle is hairy rather than scaly. It flowers through summer and is a favourite of bees and butterflies.[1]
Habitat
Grows in damp meadows, ditches, streamsides and waste ground on moist soils; native to Europe and temperate Asia.[13]
Dry grassland, meadows, pastures, dry hills, roadside banks, field margins and open woods, on well-drained and often calcareous soils across Europe and into western Asia and parts of Africa. A characteristic plant of unimproved dry meadows.[1]
Harvesting
The flowering aerial parts are cut in summer while in flower, and dried in a warm, shaded, airy place.[13]
The flowering aerial parts (leaves, stems, flower heads) are gathered in summer while in flower and dried; the root is also used. Best cut from established plants in dry grassland.[1]
Traditional Uses
Small-flowered willowherb, along with related Epilobium species, has a Central European folk tradition as a supportive remedy for lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) and prostatitis, and as an antimicrobial and anti-inflammatory herb for minor infections; the traditional prostate-support use is attributed mainly to its oenothein B content, though robust clinical evidence remains limited.[13]
Field scabious has a European folk-medicine reputation chiefly as a remedy for skin complaints - eczema, itching, scabies (the name 'scabious' comes from its use against 'the scab'), cuts and sores - taken internally as a 'blood purifier' (alterative/depurative) and applied externally as a wash or poultice. It has also been used for coughs and sore throats. The plant is rich in phenolic acids, flavonoids and saponins; the closely related genera Knautia, Scabiosa and Dipsacus in the honeysuckle family share this chemistry and a tradition of use in skin disease and inflammation.[3, 4]
Preparations
Dried flowering herb infused in hot water as a traditional urinary and prostate-support tea.
Dosage
The EU herbal monograph 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. Lower urinary tract or prostate symptoms should always be medically assessed first, and the monograph directs that a doctor be consulted if fever, spasms, blood in the urine, painful urination or urinary retention occur.
