Agrimonia eupatoria
CautionGemeiner Odermennig · (Agrimonia eupatoria)
Rose family (Rosaceae)
Description
Slender, spike-like flower stalks bearing many small yellow blossoms, followed by hooked bur fruits that cling to fur and clothing, mark this rose-family plant of summer roadsides and meadow edges. The flowering herb, harvested between June and August, is rich in catechin tannins, flavonoids and the bitter compound agrimoniin. Commission E positively assesses an infusion for mild diarrhoea, owing to the astringent tannins; a gargle for mild mouth and throat inflammation is likewise part of traditional use. Folk medicine also uses the herb as a compress for skin irritation and a foot bath for tired legs. WARNING: seek medical advice if diarrhoea lasts more than three days, if blood appears in the stool, or if fever develops; because of its tannin content, avoid taking it on an empty stomach.
Agrimony herb infusion for mild diarrhoea and digestive complaints — astringent effect of catechin tannins, positively assessed by Kommission E.

NOTE: Agrimony is considered safe when used as directed, but available clinical data are limited. During diarrhoea, ensure adequate fluid intake (fluid loss!) and consult a doctor if symptoms last more than 3 days, if there is blood in stool, or if fever occurs — severe diarrhoea can be life-threatening. For urinary tract infections, seek medical evaluation before self-treatment — bacterial infections may require antibiotics. Rare photosensitivity reactions possible (trace furocoumarins) — caution with intense sun exposure. Individual contact allergy cases have been described. Due to tannin content, avoid taking on an empty stomach — take with some food.
Not recommended in pregnancy as a precaution — no adequate clinical safety data. The EMA monograph provides no safety classification for pregnant women. In folk medicine, agrimony was occasionally used as a menstruation-promoting agent (emmenagogue) — this effect is unproven but warrants caution. Culinary amounts (occasional small amounts as herbal tea) are generally considered safe.
Not recommended during lactation due to lack of data. Transfer of constituents into breast milk has not been studied. Occasional culinary use in small amounts is generally considered safe.
Not recommended for children under 12 due to insufficient safety data (EMA). For older children (12–18 years), use only half the adult dose and after medical consultation. In children, diarrhoea can quickly lead to dangerous fluid loss — always consult a doctor.
Drug interactions
Antikoagulanzien (Warfarin, Phenprocoumon, NOAK)
Agrimony contains vitamin K (in small amounts) and tannins that may theoretically influence anticoagulant absorption. Clinical relevance at therapeutic tea doses is low, but patients on vitamin K antagonists (warfarin, phenprocoumon) should discuss regular agrimony tea use with their physician.
Eisenpräparate und andere Mineralstoff-Supplemente
Plant tannins can complex multivalent ions such as Fe²⁺/Fe³⁺ (iron), Zn²⁺ and Ca²⁺, significantly inhibiting their intestinal absorption. Do not take agrimony tea simultaneously with iron preparations or mineral supplements — maintain a gap of at least 2 hours.
Antidiabetika (orale Antidiabetika, Insulin)
In vitro and animal data suggest a mild blood glucose-lowering effect of agrimony extract (alpha-glucosidase inhibition). Combined use with antidiabetics may theoretically produce additive glucose-lowering. Clinical data are lacking; diabetics should monitor blood glucose more frequently.
Contraindications
- Hypersensitivity (allergy) to agrimony or other Rosaceae.
- Children under 12 years — insufficient safety data.
- Pregnancy and lactation (at therapeutic doses) — avoid due to lack of safety data.
- Severe kidney or liver disease — insufficient data; astringent tannins may increase strain.
Harvested part: flowering herb
- Time of day:
- On a dry, sunny morning (9–11 h), once the morning dew has fully evaporated. Harvest preferably at the beginning of flowering (June), as tannin content (and therefore astringent efficacy) in the flowering shoot tips is highest and decreases with advanced full bloom.
- Drying:
- Cut the upper 20–30 cm of flowering shoots (shoot tips with flowering spike, leaves and stem) — avoid thick, woody stem portions. Herb should not be harvested too early (unripe buds) or too late (already fruiting, fruits with hooked burs). Tie loosely in bundles and hang head down in a well-ventilated, shaded, dry room; alternatively spread thinly on screens and dry at max 40 °C. Pack away only when the herb rustles and snaps — residual moisture promotes mould. Well-dried, store in airtight dark containers (glass jars, tins) at room temperature for up to 12 months. Note the hooked fruits attach to clothing and bags — agrimony is a persistent bur-fruit carrier!
- Storage:
- 12 months — Airtight, dark, cool and dry. Use within one year. Check quality if musty smell or colour change (from green to yellow-brown) — tannin content drops sharply with poor storage.
- Time of day:
- Spring or autumn harvest (March–April before shoot emergence, or October–November after above-ground dieback). Dig during daytime when soil is not frozen. Significantly less commonly used than the herb in folk medicine.
- Drying:
- Dig roots, clean of soil and briefly rinse (do not soak). Halve lengthways or slice into ~1–2 cm pieces. Dry at max 40–50 °C in dehydrator or oven with door slightly ajar until pieces are hard and dry when broken. Scent is astringent and tannic. For traditional tinctures the fresh root may be immediately immersed in alcohol (1:5, 40–60 % ethanol). Note: The root was historically used in tannin decoctions for severe diarrhoea and externally for wound washing; now rarely used.
- Storage:
- 24 months — Dried root slices in tight tins or screw-top jars, dark, dry and cool — up to 2 years shelf life (tannins are more stable in roots than in the herb).
- Catechingerbstoffe (Catechin, Epicatechin, kondensierte Tannine)TanninContent: 4-10 %Aerial parts
Lead compound group of agrimony (Herba Agrimoniae). Condensed catechin tannins dominate; they act strongly astringently on mucous and skin surfaces via protein precipitation. Mainly responsible for the antidiarrhoeal and anti-inflammatory effect on the intestinal mucosa and oropharynx. Content varies with harvest time (highest before full flowering).
- Gallotannine (Corilagin, Ellagtannine — hydrolysierbare Gerbstoffe)TanninContent: 0.5-2 %Aerial parts
Hydrolysable tannins including corilagin as a lead compound. Complement the effect of condensed tannins; additionally antibacterial and antiviral in vitro. Intestinal hydrolysis releases gallic acid and ellagic acid, which act as antioxidants.
- Flavonoide (Luteolin, Apigenin, Quercetin, Kämpferol — als Glykoside)FlavonoidContent: 1-3 %Aerial parts
Apigenin and luteolin dominate as flavone aglycones (mainly as 7-glucuronides). Quercetin and kaempferol as flavonol glycosides in smaller proportions. Antioxidant, mildly anti-inflammatory and spasmolytic; contribute to the overall whole-extract effect. Luteolin shows alpha-glucosidase inhibition in vitro.
- Triterpene und Triterpensäuren (Ursolsäure, Oleanolsäure)OtherContent: 0.5-1.5 %Aerial parts
Pentacyclic triterpenes, in agrimony mainly ursolic acid and oleanolic acid. Anti-inflammatory, antimicrobial and mildly hepatoprotective in vitro and animal studies. Contribute to the traditional use as a liver tonic. Content is low; clinical relevance in humans not confirmed by studies.
- Phenolcarbonsäuren (Chlorogensäure, Kaffeesäure, p-Cumarsäure)Phenolic acidContent: 0.3-1 %Aerial parts
Hydroxycinnamic acid derivatives with antioxidant and mildly antimicrobial properties. Chlorogenic acid inhibits lipid peroxidation in vitro and shows mild alpha-glucosidase inhibition. Complements the phenolic activity spectrum of flavonoids and tannins.
- Bitterstoffe (Agrimoniin, Isoagrimoniin)BitterContent: 0.5-2 %Aerial parts
Dimeric ellagitannins (agrimoniin = main bitter compound). Responsible for the characteristic bitter astringent taste of the tea. In vitro cytotoxic and antitumoral properties described (agrimoniin against human tumour cell lines), but not transferable to therapeutic use in humans. Reflexively stimulate bile flow and gastric juice secretion.
- Ätherisches Öl (Spuren — Terpene, Sesquiterpene)Essential oilContent: 0.01-0.2 %Aerial parts
Very small amounts of volatile oils, mainly mono- and sesquiterpenes (incl. alpha-pinene, limonene, caryophyllene). Responsible for the characteristic mildly apple-like aroma of the fresh herb. Pharmacologically irrelevant at the concentrations remaining in tea.
- Kieselsäure und Mineralien (Silicium, Kalium, Calcium)MineralContent: 1-3 % GesamtascheAerial parts
Agrimony contains silicic acid (silicon dioxide) in notable amounts, traditionally highlighted for use in skin and connective tissue. Potassium supports the diuretic component. Calcium contributes to mineral supply. Content varies considerably with location and soil composition.
