Safety, Cautions & Contraindications
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).
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 that persists (especially in children) needs medical assessment and attention to rehydration.
External Ids
Botanical Description
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.
Scrambling, thorny deciduous shrub (Rosaceae) forming dense thickets, with arching prickly stems that root at the tip. Leaves are palmately compound, usually with 3-5 toothed leaflets. White to pale pink, five-petalled flowers are followed by clusters of small drupelets forming the blackberry fruit, ripening from red to glossy black.[8]
Habitat
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.
Native throughout Europe and widely naturalised elsewhere, an aggressive coloniser of hedgerows, woodland edges, scrub and waste ground. 'Rubus fruticosus' is a taxonomically complex aggregate comprising hundreds of closely related microspecies.[8]
Harvesting
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.
Leaves are picked fresh throughout the growing season and dried for tea; berries are picked in late summer once fully ripe.[8]
Traditional Uses
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]
Blackberry leaf has a long European folk-medicine tradition as an astringent gargle for sore throat and mouth ulcers, and as a remedy for mild diarrhoea, reflecting its high tannin content; the berries themselves are valued as a nutritious, antioxidant-rich food.[8]
Preparations
Dosage
Traditional guidance suggests roughly 2-4 g dried leaf per cup as an infusion, up to three times daily, or used as a gargle at similar strength. Educational reference only, not a prescription.
