Key Constituents
Very high tannin content is the basis of the strong astringency.
Contribute to antioxidant and antibacterial activity.
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)
Anti-inflammatory and antiproliferative (slows the skin-cell overgrowth of psoriasis)
Anti-inflammatory and antiproliferative (slows the skin-cell overgrowth of psoriasis)
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
inferred from anticancer action
Topical for atopic dermatitis (eczema) and skin irritation
Antimicrobial (berberine) - supports skin and mucosal infection
inferred from anti-inflammatory action
Anti-inflammatory and antiproliferative (slows the skin-cell overgrowth of psoriasis); Topical treatment of mild-to-moderate psoriasis (reduces plaque severity) - a double-blind, placebo-controlled RCT showed significant improvement in PASI and quality-of-life scores
Topical for atopic dermatitis (eczema) and skin irritation
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.
Avoid internal use in pregnancy and breastfeeding: like goldenseal, the berberine it contains can cross the placenta and into milk and worsen newborn jaundice (kernicterus risk).

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]
Evergreen shrub, 0.5-2 m tall, spreading by underground rhizomes to form thickets. The pinnate leaves resemble holly, with 5-9 glossy, dark green, spiny-toothed leaflets that often turn bronze-red in winter. Small, bright yellow, six-petalled flowers are borne in dense, upright terminal racemes in early spring, followed by clusters of blue-black, grape-like berries with a waxy bloom. The wood and inner bark of the stem and root are bright yellow when cut, owing to their high content of berberine-type alkaloids.
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]
Native to the Pacific Northwest of North America, growing in coniferous woodland understorey, forest margins and rocky slopes; widely introduced and naturalised as an ornamental and hedging shrub in temperate regions 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 root and root bark, the medicinal parts, are dug from established plants - traditionally in autumn - and dried. Because wild populations are slow-growing, cultivated or nursery-sourced material is preferred over wild-harvesting.
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]
Oregon grape root has a traditional Native American and Eclectic-medicine history as a bitter tonic and alterative (blood-purifying) remedy and for skin conditions. Its main modern use, supported by clinical trials, is topical application of a standardised bark extract for mild-to-moderate psoriasis and atopic dermatitis (eczema), where its berberine-type alkaloids give anti-inflammatory and antiproliferative effects on skin cells.[1, 11, 12]
