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.
Flavonol glycosides including spiraeoside (quercetin 4'-O-glucoside), hyperoside, rutin and kaempferol derivatives - the signature Filipendula flavonoids.
Ellagitannins and gallotannins (astringent constituents), giving the traditional astringent/antidiarrhoeal action.
Gallic, caffeic, chlorogenic and ferulic acids; antioxidant.
Catechin-based condensed tannins.
Pharmacological Actions
Antihyperalgesic in a rat inflammatory-pain model (salicylate-mediated).
Traditional use for rheumatic/arthritic pain, consistent with salicylate content and analgesic/anti-inflammatory activity.
Protective against carbon-tetrachloride liver injury in rats.
Hydrolysable-tannin astringency underlying traditional antidiarrhoeal and wound/gargle use.
Nootropic and brain-bioenergetic effects in animal models (Russian traditional nervous-system use).
Dropwort extract restrained the YAP/TAZ/TEAD oncogenic axis in mesothelioma (preclinical).

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.
Dropwort contains salicylate compounds (salicylaldehyde, methyl salicylate), as in meadowsweet and willow. Avoid in salicylate or aspirin sensitivity, and use caution alongside anticoagulant or antiplatelet medicines. As with other salicylate-containing plants, avoid in children with viral illness (theoretical Reye's syndrome risk).
Safety in pregnancy and breastfeeding has not been established; avoid medicinal doses during pregnancy and lactation.

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]
Erect perennial herb of the rose family, 20-80 cm tall, growing from a short rootstock whose fibrous roots bear characteristic small tuber-like swellings (the 'drop-wort' beads). The leaves are mostly in a basal rosette and are distinctive: long, fern-like and interruptedly pinnate, with many (up to 20+ pairs) small, deeply toothed leaflets. Small creamy-white flowers, often pink-tinged in bud and 6-petalled, are borne in an irregular terminal cyme. Unlike its sibling meadowsweet (Filipendula ulmaria) of wet ground, dropwort grows in dry calcareous grassland.[1, 6]
Habitat
Grows in damp meadows, ditches, streamsides and waste ground on moist soils; native to Europe and temperate Asia.[13]
Dry, unimproved calcareous (chalk and limestone) grassland, meadows, roadside banks and open scrub. Native across most of Europe, western Asia and North Africa. Unlike meadowsweet (F. ulmaria), which grows in wet meadows and beside water, dropwort is a plant of dry ground.[1]
Harvesting
The flowering aerial parts are cut in summer while in flower, and dried in a warm, shaded, airy place.[13]
The flowering tops and aerial parts are gathered in summer while in flower; the fern-like leaves and the small root tubers are also used. The material is dried for infusions and decoctions.[2]
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]
Dropwort shares much of the European folk-medicine history of its sibling meadowsweet. The salicylate- and tannin-rich herb has been used as an astringent and anti-inflammatory remedy for diarrhoea and other gastrointestinal complaints, for rheumatic and arthritic pain, for kidney and bladder 'gravel' and urinary complaints, and as a wound and mouth wash. In Serbian and Balkan ethnomedicine the flowers and roots are used; Russian traditional medicine uses dropwort extracts as a nootropic and calming remedy for the nervous system.[2, 12, 15]
Preparations
Dried flowering herb infused in hot water as a traditional urinary and prostate-support tea.
Dried flowering tops or leaves infused as an astringent, anti-inflammatory tea for digestive and rheumatic complaints.
The root and root-tubers decocted; used traditionally for diarrhoea and urinary 'gravel'.
The flowers yield an aromatic oil dominated by salicylaldehyde with antimicrobial activity (as in meadowsweet).
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. Educational reference only, not a prescription.

Pairings
Not documented
Sibling species: both are salicylate- and tannin-rich Rosaceae with overlapping anti-inflammatory, analgesic, astringent and gastroprotective uses (dropwort of dry grassland, meadowsweet of wet meadows); studied together in the same trials.[2, 3]
Both are salicylate-containing anti-inflammatory and analgesic herbs (the classic plant-aspirin group), traditionally combined for rheumatic pain and fever.[10]
Rosaceae astringents rich in hydrolysable tannins, traditionally used for diarrhoea and as gargles; studied together for antioxidant and genotoxicity profile.[16]
