Uva Ursi

Uva ursi, or bearberry, is the dried leaf of Arctostaphylos uva-ursi (L.) Spreng., a low evergreen shrub of the heath family native to the cooler regions of Europe, Asia and North America. Nustras supplies it as a dried leaf powder and as a leaf extract powder; the leaf's characteristic constituents are the hydroquinone glycoside arbutin, together with tannins, flavonoids and phenolic acids.

The material is formulated into botanical and herbal supplements in capsule, tablet and powder form, into multi-herb blends and premixes, and into herbal teas where a bearberry leaf ingredient is required.

The material is a brown to yellow-brown or olive powder. Arbutin content or extract ratio, loss on drying and particle size are standardised to specification; identity is confirmed by thin-layer chromatography according to USP methods, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies uva ursi in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Bearberry leaf is a regulated botanical whose status differs between markets, some classifying it as a herbal medicine; buyers confirm the permitted plant part, arbutin level, product category and claim for their application.
