Safety, Cautions & Contraindications

Safety note[14]Info

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.

Safety note[14]Caution

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.

Safety note[10]Serious

As a member of the borage family (Boraginaceae), which can contain hepatotoxic pyrrolizidine alkaloids, prolonged or high-dose internal use is best avoided; use in pregnancy and breastfeeding is not recommended.

Safety note[10]Info

Traditional use only; clinical evidence in humans is limited, so a cough or respiratory complaint that persists needs medical assessment.

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]

Height: Low, sprawling to semi-erect, stems to about 30-45 cm
Habit: Low, sprawling to semi-erect perennial herb
Leaves: Palmate, typically 4-5 leaflets, with large leaf-like stipules
Flowers: Small, yellow, four-petalled (unusual among Potentilla species)
Stem: Wiry, sprawling to semi-erect
Root: Thick, woody rhizome, reddish inside when cut
Fruit: Small dry achenes (typical Rosaceae)
Flowering Period: May-September

Low, hairy perennial herb (Boraginaceae), 15-30 cm tall. Basal leaves are long-stalked, ovate to lance-shaped, often white-spotted - the spotted pattern was historically likened to diseased lung tissue under the medieval Doctrine of Signatures, giving rise to the name 'lungwort' - and covered in bristly hairs. Funnel-shaped flowers open pink and turn blue as they mature, borne in small coiled clusters (cymes).[10]

Height: 15-30 cm
Habit: Low, hairy perennial herb
Leaves: Long-stalked, ovate to lance-shaped, often white-spotted, bristly-hairy
Flowers: Funnel-shaped, opening pink and turning blue with age, in small coiled cymes
Stem: Hairy, low-growing
Root: Short rhizome with fibrous roots
Fruit: Small nutlets (typical Boraginaceae)
Flowering Period: March-May

Habitat

Native to Europe and western Asia, common in acidic grassland, heath, moorland, open woodland and pastures on poor, well-drained soils.[14]

Native to central and southern Europe, growing in damp, shaded woodland, hedgebanks and scrub on humus-rich soils; widely cultivated as a shade garden plant.[10]

Harvesting

The rhizome is dug in autumn or early spring, when tannin content is highest, then cleaned and dried.[14]

Parts: Rhizome
Season: Autumn or early spring

Aerial flowering parts are cut during flowering (spring); the plant can also be gathered later in the growing season, though the phenolic constituent profile is documented to differ measurably between spring and autumn harvests.[11]

Parts: Aerial parts (flowering herb)
Season: Spring (flowering); constituent profile varies spring vs autumn

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]

Lungwort's spotted leaves inspired its traditional use, under the Doctrine of Signatures, as a remedy for lung and respiratory complaints - coughs, bronchitis, catarrh and sore throat - valued for its soothing mucilage and astringent tannins. Modern research confirms antioxidant and anti-inflammatory (COX-2-inhibiting) activity of its phenolic-rich extract, though clinical trial evidence in humans remains limited.[10]

Preparations

Decoction[14]

Dried rhizome simmered in water, the standard astringent preparation for diarrhoea.

Tincture[15]

Alcoholic extract, taken diluted or used as a gargle/mouthwash.

Gargle/mouthwash[15]

Diluted decoction or tincture used for sore throat and mouth inflammation.

Infusion (tea)[10]

Dried aerial parts steeped in hot water, the traditional respiratory remedy.

Dosage

Decoction/tincture[14, 15]

EMA/ESCOP guidance suggests around 4-6 g dried rhizome (or an equivalent decoction), divided into 2-3 doses daily, for diarrhoea, or a diluted tincture used as a gargle several times daily. Educational reference only, not a prescription.

Infusion (tea)[10]

Traditional guidance suggests roughly 2-4 g dried herb per cup as an infusion, up to three times daily, for short-term use; avoid prolonged or high-dose internal use given the borage family's potential pyrrolizidine-alkaloid content. Educational reference only, not a prescription.
