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 high mucilage content gives the demulcent, soothing action.
The blue-purple pigments and antioxidant constituents.
Phenolic constituents associated with antioxidant and reported antiproliferative (anticancer) activity in cell studies.
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, analgesic and wound-healing (preclinical)
Antibacterial / antimicrobial (methanolic leaf extracts; the naphthoquinone Malvone A)
Demulcent for irritation of the mouth or throat and associated dry cough (soothing mucilage); Mild laxative for occasional constipation (mucilage; traditional)
Mild laxative for occasional constipation (mucilage; traditional)

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.
Generally very well tolerated. Irritation of the mouth/throat or a cough that persists beyond about a week, or is accompanied by fever or breathlessness, needs medical assessment.
Use in pregnancy and breastfeeding is not recommended in the absence of adequate data.

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]
Biennial or short-lived perennial herb, 30-120 cm tall, with erect or sprawling, branched, often reddish stems. Leaves are alternate, long-stalked and palmately lobed with 5-7 shallow rounded lobes and toothed margins. Flowers are pink-purple with darker veining, with five notch-tipped petals borne in small axillary clusters. The fruit is a flattened, disc-shaped schizocarp ('cheese') that splits into a ring of small single-seeded nutlets.[2]
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]
Common on roadsides, waste ground, hedgebanks and field margins across Europe, North Africa and temperate Asia, and widely naturalised elsewhere; tolerates a wide range of soils, favouring sunny, disturbed, nitrogen-rich sites.[2]
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]
Leaves and flowers are gathered during the flowering period (summer) and dried quickly out of direct sun to preserve their mucilage content; fresh material can also be used directly for infusions or poultices.[11]
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]
Mallow leaf and flower have a long ethnobotanical history across Europe as a demulcent for irritated mucous membranes - soothing coughs, sore throat and mouth irritation - and for occasional constipation and skin irritation, reflecting the mucilage-rich leaf and flower. Modern phytochemical and pharmacological work confirms antioxidant, anti-inflammatory, antimicrobial and wound-healing activity of its extracts.[2, 11]
