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 principal astringent and anti-inflammatory constituents.
Antioxidant and anti-inflammatory constituents of the bark and leaf.
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).
Anti-inflammatory and antioxidant (supports irritated/atopic skin); Relief of haemorrhoid symptoms (astringent and anti-inflammatory)
Astringent for skin irritation and minor inflammation of the skin and oral mucosa (tannins), applied topically; Relief of haemorrhoid symptoms (astringent and anti-inflammatory)

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.
For topical use. Do not apply to deep wounds, serious burns or severe rectal bleeding - these need medical care.

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]
Large, multi-stemmed deciduous shrub or small tree with broad, oval, wavy-toothed leaves, asymmetrical at the base. Unusually, it flowers in late autumn to winter after the leaves have fallen, bearing clusters of small, spidery, bright yellow flowers with narrow, crinkled, ribbon-like petals. The woody seed capsule matures the following autumn and explosively ejects its seeds ('snapping hazelnut').[14]
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 woodland understorey and forest margins of eastern North America; widely cultivated as an ornamental and medicinal shrub.[14]
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]
Bark is stripped from branches (not the main trunk, to avoid harming the plant) and leaves are picked in summer; both are dried for use, or steam-distilled together with twigs to produce distilled witch-hazel water, the most common commercial form.[14]
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]
Witch hazel has a long Native American and, after adoption by European settlers, worldwide reputation as a topical astringent and anti-inflammatory remedy for skin irritation, minor wounds, bruises, insect bites and haemorrhoids, and as a soothing wash for irritated skin and mucous membranes.[14]
