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
Astringent for mild diarrhoea (tannins)
Astringent for menstrual cramps (traditional); Astringent for mild diarrhoea (tannins)
Traditional uterine tonic taken in late pregnancy to tone the uterus and support labour - one small double-blind RCT found a shorter second stage of labour and fewer forceps deliveries (no effect on the first stage), alongside observational signals; robust proof is still lacking
Traditional & Indicated Uses

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
Supportive in inflammatory bowel disease / ulcerative colitis (limited trial evidence)
Anti-inflammatory gargle / mouthwash for sore throat and inflammation of the mouth and throat
inferred from astringent action
Anti-inflammatory gargle / mouthwash for sore throat and inflammation of the mouth and throat
Astringent for menstrual cramps (traditional)
inferred from emmenagogue action
inferred from astringent action
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.
Diarrhoea persisting more than 3-4 days, or with fever or blood in the stool, needs medical care. Use in pregnancy and breastfeeding is not recommended in the absence of data.

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]
Deciduous, thicket-forming shrub (Rosaceae), 1-2 m tall, with upright, prickly, biennial canes (vegetative in the first year, fruiting in the second). Leaves are pinnate with 3-7 toothed leaflets, whitish-felted beneath. Small white, five-petalled flowers are followed by the aggregate red raspberry fruit, a cluster of drupelets.[2]
Habitat
Harvesting
The rhizome is dug in autumn or early spring, when tannin content is highest, then cleaned and dried.[14]
Leaves are picked fresh during the growing season - before or during flowering is considered optimal - and dried; fruit is picked when fully ripe in summer.[2]
Traditional Uses
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]
Raspberry leaf has a long, very widely known folk tradition as a 'pregnancy tea', taken in the final weeks of pregnancy as a uterine tonic to prepare for labour. Observational studies and a small randomised controlled trial suggest a possible modest effect on labour duration, though robust proof is still lacking.[1, 13]
Preparations
Dosage
Popular guidance and observational studies generally describe starting raspberry-leaf tea or tablets in the last few weeks of pregnancy, at roughly 1-3 cups of tea daily; use should be discussed with a midwife or doctor given the lack of robust trial evidence. Educational reference only, not a prescription.
