Botanical Description
Low, sprawling to semi-erect perennial herb (Rosaceae) with wiry stems. Leaves are palmate, typically with 4-5 leaflets and large leaf-like stipules that give the impression of more leaflets. Flowers are small, yellow and four-petalled - unusual among Potentilla species, most of which have five petals. The thick, woody rhizome is reddish inside when cut, the origin of the old name 'bloodroot' for this European species.[14]
Habitat & Distribution
Native to Europe and western Asia, common in acidic grassland, heath, moorland, open woodland and pastures on poor, well-drained soils.[14]
Harvesting
The rhizome is dug in autumn or early spring, when tannin content is highest, then cleaned and dried.[14]
Key Constituents
Pharmacological Actions
Anti-inflammatory gargle / mouthwash for sore throat and inflammation of the mouth and throat
Astringent for mild diarrhoea (ellagitannins tighten the gut lining) - in a paediatric RCT, tormentil root extract shortened rotavirus diarrhoea (3 vs 5 days) and reduced rehydration needs
Traditional & Indicated Uses

Traditional Use & History
Tormentil rhizome has an official European herbal-monograph tradition for mild diarrhoea and inflammation of the mouth and throat, reflecting its long folk use as a powerful astringent for gut and mucous-membrane complaints. Modern trials confirm its ellagitannin-rich rhizome shortens the duration of infectious (rotavirus) diarrhoea.[8, 14, 15]
Preparations
Dosage
Safety, Cautions & Contraindications
Tannin-rich: high or prolonged intake may cause stomach upset or constipation and can reduce the absorption of iron and some medicines taken at the same time.
