Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Very high tannin content is the basis of the strong astringency.
Contribute to antioxidant and antibacterial activity.
Verbascoside, tiliroside and quercetin/kaempferol 3-O-glucosides in the flowers.
Lamalbid, alboside A and B and caryoptoside; linked to antioxidant and anti-inflammatory activity.
Lamalbid, chlorogenic acid, verbascoside, rutin and tiliroside, richest in the flowering tops.
Pharmacological Actions
Anti-inflammatory gargle / mouthwash for inflammation of the mouth and throat (sore throat)
Bistorta officinalis (Polygonum bistorta) rhizome extract, rich in gallotannins and phenolic acids, shows cytotoxic and pro-apoptotic activity against hepatocellular and other cancer cells (preclinical).
Astringent for mild diarrhoea (tannins tighten the gut lining and reduce excess secretion)
Antibacterial (topical) - GC-MS-characterised extracts showed antibacterial activity
Astringent for mild diarrhoea (tannins tighten the gut lining and reduce excess secretion)
Astringent and anti-inflammatory infusion or tincture (flowering tops)
Astringent (catarrh, excessive menstrual or vaginal discharge); Astringent and anti-inflammatory infusion or tincture (flowering tops)
Traditional & Indicated Uses
inferred from anti-inflammatory action
Polygonum bistorta (Bistorta officinalis) methanol-water and aqueous extracts inhibit hepatocellular carcinoma cells via ROS-induced ER stress and apoptosis (delaying xenograft tumour growth), with phenolic constituents driving the cytotoxicity (preclinical).
Astringent for mild diarrhoea (tannins tighten the gut lining and reduce excess secretion)
inferred from styptic action
inferred from antimicrobial action
Anti-inflammatory gargle / mouthwash for inflammation of the mouth and throat (sore throat)
inferred from astringent action
Anti-inflammatory gargle / mouthwash for inflammation of the mouth and throat (sore throat)
inferred from anti-inflammatory action
Astringent (catarrh, excessive menstrual or vaginal discharge)
inferred from anti-inflammatory action
inferred from expectorant action
inferred from astringent action
Safety, Cautions & Contraindications
Very 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.
Traditional use only; diarrhoea persisting beyond a few days, or mouth/throat inflammation that does not settle, needs medical assessment.
Safety in pregnancy and breastfeeding is not established; avoid medicinal doses.
Generally regarded as safe in culinary amounts and at normal medicinal doses; unlike the stinging nettle it has no stinging hairs.
Medicinal use during pregnancy or breastfeeding should be approached cautiously, as for any traditional astringent.
Identify correctly before foraging (resembles stinging nettle before flowering and red dead-nettle); clinical evidence is limited, so it should not replace conventional treatment.

Botanical Description
Perennial herb rising from a thick, twisted, S- or snake-shaped rhizome (giving the names 'bistort' and 'snakeroot'), blackish outside and pink inside. The basal leaves are broadly oval to lance-shaped on long stalks; stem leaves are smaller and stalkless. A single dense, cylindrical spike of small, pale pink flowers is borne atop each unbranched flowering stem.[14]
Perennial herb closely resembling stinging nettle in leaf shape but entirely without stinging hairs. Square stems bear opposite, toothed, heart-shaped leaves, and whorls of white, hooded, two-lipped flowers cluster in the upper leaf axils.[15]
Habitat
Grows in damp meadows, pastures, streamsides and mountain grassland on moist, often calcareous soils; native to Europe and temperate Asia, favouring cooler upland regions.[14]
Grows in hedgerows, waste ground, gardens and roadsides on nitrogen-rich soils; native to Europe and temperate Asia, widely naturalised elsewhere.
Harvesting
The rhizome is dug in autumn or early spring, when tannin content is highest, cleaned and dried; aerial parts are gathered in summer while flowering.[14]
The flowering tops are picked as they open, largely through spring to autumn given the long flowering season, and dried in a warm, shaded, airy place; the standardisation markers are richest in the flowering tops specifically.[15]
Traditional Uses
Bistort rhizome, one of the most tannin-rich temperate herbs, has a long European folk history as a powerful astringent for mild diarrhoea, as a gargle for sore throat and mouth inflammation, and topically as a vulnerary and styptic for minor wounds and bleeding; young leaves have also traditionally been eaten as a spring pot-herb ('Easter-ledge pudding').[13, 14]
White dead-nettle flower has a long European folk history as an astringent remedy for catarrh and excessive menstrual or vaginal discharge, and topically as a vulnerary wash for minor wounds; the young leaves and shoots have also traditionally been eaten as a cooked spring pot-herb.
