Key Constituents
Very high tannin content is the basis of the strong astringency.
Contribute to antioxidant and antibacterial activity.
Phenolic monoterpenes responsible for the strong antimicrobial activity.
Antioxidant constituents.
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)
Antimicrobial (antibacterial and antifungal via carvacrol and thymol) - supports respiratory and gastrointestinal infections; a small clinical study found emulsified oregano oil cleared enteric parasites (incl. Blastocystis hominis) and improved gut symptoms
Antimicrobial (antibacterial and antifungal via carvacrol and thymol) - supports respiratory and gastrointestinal infections; a small clinical study found emulsified oregano oil cleared enteric parasites (incl. Blastocystis hominis) and improved gut symptoms
Carminative digestive for indigestion (traditional bitter aromatic)
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).

inferred from styptic 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.
Culinary amounts are safe. Concentrated oregano essential oil is a strong irritant - dilute well before any topical use and do not take undiluted oil internally.
May lower blood sugar and has a mild antiplatelet effect, so use caution with antidiabetic or anticoagulant medicines; avoid medicinal/oil doses in pregnancy. Allergy is possible in people sensitive to the mint family (Lamiaceae).

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/subshrub (Lamiaceae), 20-80 cm tall, with square, often reddish, downy stems. Leaves are opposite, ovate and aromatic. Small purplish-pink (occasionally white) flowers are borne in dense, flattened, corymb-like clusters at the branch tips.[11]
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 Mediterranean, Europe and temperate Asia and widely naturalised elsewhere, growing on dry, sunny grassland, banks and scrubby hillsides, typically on calcareous soils.[11]
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]
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]
Oregano has a long Mediterranean culinary-medicinal tradition as an aromatic digestive bitter and antiseptic remedy for coughs, colds and infections. Modern research on its carvacrol- and thymol-rich essential oil strongly supports broad antibacterial, antifungal and antioxidant activity, consistent with these traditional uses.[11, 12]
Preparations
Dried herb steeped in hot water as a digestive, aromatic tea.
The most-studied form; concentrated oil is a strong irritant and must be well diluted before topical use and never taken undiluted internally.
A small clinical study used an emulsified oregano oil preparation to clear enteric parasites and improve gut symptoms; oral use of concentrated oil should be supervised.

Dosage
Not documented
Culinary amounts (as a food seasoning or mild tea) are considered safe; concentrated essential oil should only be used well diluted and is not intended for undiluted internal use without professional guidance. Educational reference only, not a prescription.
