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
Hydroquinone glycoside; hydrolysed and excreted as antibacterial hydroquinone in the urine.
Up to ~20%; responsible for the astringency and for gastric irritation at high doses.
Pharmacological Actions
Arbutin, the hydroquinone glucoside characteristic of bearberry (Arctostaphylos uva-ursi), shows antiproliferative and pro-apoptotic activity across multiple cancer types (preclinical).
Antibacterial in the urinary tract (arbutin is converted to antibacterial hydroquinone, favoured by alkaline urine); Urinary antiseptic for mild, uncomplicated lower urinary tract infection / cystitis (short-term)
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
The bearberry constituent arbutin suppresses osteosarcoma proliferation, migration and invasion via miR-338-3p/MTHFD1L and AKT/mTOR inactivation, and has documented anticancer potential against bladder, breast, colon, liver and other cancers (preclinical).
Urinary antiseptic for mild, uncomplicated lower urinary tract infection / cystitis (short-term)
inferred from astringent action
inferred from urinary-antiseptic action
Antibacterial in the urinary tract (arbutin is converted to antibacterial hydroquinone, favoured by alkaline urine); Urinary antiseptic for mild, uncomplicated lower urinary tract infection / cystitis (short-term)
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
Short-term use only: not for more than 1 week at a time and not more than about 5 times per year. If symptoms persist beyond ~4 days, worsen, or are accompanied by fever, blood in the urine or pain, seek medical care.
Contraindicated in pregnancy and breastfeeding and not for use in children or adolescents under 18 years.
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
Low, mat-forming evergreen shrub with trailing, woody stems that root as they spread. The leaves are small, leathery, spatula-shaped (spoon-shaped), glossy dark green above and paler beneath, with a smooth, untoothed margin and a rounded tip. Small, urn-shaped, pink-and-white flowers hang in short clusters in spring, followed by bright red, mealy berries.[11]
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 on dry, acidic, sandy or rocky ground in open woodland, heath, moorland and mountain slopes across the northern hemisphere (Europe, Asia and North America), often in exposed, cold, upland or subarctic sites.[11]
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 leaves are gathered in autumn to early spring (outside the flowering and fruiting season), when arbutin content is at its highest, and dried carefully to preserve the glycoside.[11]
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
Bearberry leaf is a long-established European folk and official (EU herbal monograph) remedy for mild, uncomplicated lower urinary tract infections and cystitis, used short-term as a urinary antiseptic; it has also been used traditionally as an astringent for mild diarrhoea.[11]
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]
Preparations
Dried leaf macerated in cold water for several hours, which extracts less tannin (reducing gastric irritation) than a hot infusion; the preferred traditional preparation.
Dried leaf infused or lightly decocted in hot water; alkalinising the urine (e.g. with dietary measures) is traditionally recommended alongside use, since arbutin's antibacterial action requires alkaline urine.
Dosage
The EU herbal monograph describes traditional use of about 3 g dried leaf per cup, up to four times daily, for no more than one week at a time and no more than about five times a year. Educational reference only, not a prescription.
