Key Constituents
Hydrolysable ellagitannins - the dominant astringent constituents of water avens.
Additional hydrolysable and condensed tannins contributing to the astringent, antidiarrhoeal and elastase-inhibiting activity.
Ellagic acid and ellagic-acid glycosides (antioxidant; precursors of anti-inflammatory urolithins in the gut).
Gallic acid and galloyl derivatives (antioxidant, antimicrobial).
Antioxidant flavonol glycosides.
Triterpenoid saponins and aglycones.
The root essential oil is dominated by eugenol, giving the clove-like scent (shared with clove) and antiseptic, mild-anaesthetic character.
The A-type proanthocyanidins are considered responsible for inhibiting bacterial adhesion to the urinary tract lining.
Give the fruit its characteristic tartness and are traditionally credited with a mild urinary-acidifying effect.
Pharmacological Actions
Astringent hydrolysable tannins; traditional remedy for diarrhoea and dysentery.
Inhibits prostaglandin biosynthesis; ellagitannin-derived urolithins are anti-inflammatory.
Geum (avens) extracts show antineoplastic and skin antineoplastic activity in vitro (preclinical).
Antiviral activity of avens (Geum) extract in vitro (congener).
Neuroprotective activity of water avens polyphenol fractions.
Avens root extract showed antidiabetic (glucose-lowering) activity in vivo (congener G. urbanum).

Safety, Cautions & Contraindications
The root and herb are rich in tannins; large or prolonged doses may cause digestive upset or constipation and can reduce the absorption of iron and some medicines - take apart from iron supplements and other drugs.
Safety in pregnancy and breastfeeding has not been established; avoid medicinal doses during pregnancy and lactation.
In-vivo toxicity testing of avens (Geum) extract showed a favourable profile at the doses studied, but high-dose or long-term safety is not established.
Food amounts are generally considered safe (berries in meals, drinks, sauces). (Williams et al., 2023).
Duke (2002) includes cranberry primarily at the experimental level for its astringent, diuretic, and antioxidant properties. Commission E has not approved cranberry for specific indications, though there is evidence supporting its role in preventing urinary tract infections (UTIs) by inhibiting bacterial adhesion to uroepithelial cells (proanthocyanidins). Duke notes the high vitamin C and organic acid content. Food-grade consumption is considered safe and beneficial as a urinary acidifier (Duke, 2002).

Botanical Description
A perennial herb of the rose family, 20-60 cm tall, growing from a thick, reddish, aromatic rhizome that smells of cloves when broken (from its eugenol content) - the source of the name 'chocolate root'. The basal leaves are pinnate with a large terminal lobe, forming a rosette. Its distinctive flowers are nodding (drooping) bells with dull purple-pink to orange sepals and cream-to-pink petals, quite unlike the erect open yellow flowers of its relative wood avens (Geum urbanum). The fruit is a rounded head of achenes, each with a hooked, feathery style that clings to fur and clothing.[1, 9]
Low, creeping, evergreen dwarf shrub (Ericaceae) with slender, wiry stems that root at the nodes. Leaves are tiny, alternate, leathery and ovate with in-rolled margins, dark green above and whitish beneath. Flowers are small, pink and four-petalled, sharply reflexed backward so that the protruding stamens and style resemble a crane's head and neck - the origin of the name 'craneberry', later shortened to 'cranberry'. The fruit is a small, round, tart red berry.[8]
Habitat
Damp ground: wet meadows, marshes, streamsides, ditches, fens and damp woodland across Europe, western Asia and North America. It favours moist, base-rich soils. Unlike wood avens (Geum urbanum), a plant of dry hedgerows and shade, water avens grows in wet, open places.[1]
Native to boggy, acidic wetlands - sphagnum bogs and marshes - across northern and central Europe and northern Asia, requiring waterlogged, nutrient-poor, acidic peat soils.[8]
Harvesting
The reddish rhizome/root is the main medicinal part, dug in spring or autumn and dried carefully to preserve its clove-scented, eugenol-bearing, tannin-rich qualities; the aerial flowering parts are gathered in summer. The root has historically been used both as an astringent medicine and as a flavouring (a coffee/chocolate substitute and to flavour ale).[5, 9]
Berries are hand-picked or wet-harvested (traditionally by hand-raking the bog) in autumn once fully ripe and deep red.[8]
Traditional Uses
Water avens shares the astringent, tannin-based traditional medicine of the avens (Geum) genus. The clove-scented root has been used as an astringent for diarrhoea, dysentery and other bowel complaints, as a gargle and mouth wash for sore throat, mouth ulcers and spongy gums, and as a wash for wounds and skin inflammation. It was also valued as an aromatic bitter tonic and, historically, a febrifuge, and the fragrant root was used to flavour ale and as a coffee/chocolate substitute (hence 'chocolate root').[8, 9]
Cranberry has a long northern-European and Native American tradition as a food and folk remedy for urinary complaints, valued for its tart, astringent, vitamin-C-rich fruit. Modern research on its proanthocyanidins supports a role in reducing bacterial adhesion in the urinary tract, consistent with the traditional use for cystitis and recurrent urinary tract infections.[2, 11]
