Oregon Grape

Oregon grape is the root and stem bark of Mahonia aquifolium, an evergreen shrub of the barberry family native to western North America. Nustras supplies Oregon grape as dried cut root, root powder and root extract for the herbal supplement category. The root is characterised by isoquinoline alkaloids, principally berberine, which give it its yellow colour.

Oregon grape root is formulated into capsules, tablets and powder blends, liquid extracts, tinctures, bitters and multi-botanical premixes, generally in traditional-style formulas.

Dried root is yellowish-brown outside and bright yellow within, bitter in taste; powder is yellow-brown; extracts are yellow-brown to brown. Identity is confirmed by HPTLC against reference material, and the berberine content of extracts is standardised to specification and assayed by HPLC. Heavy-metal, pesticide-residue and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies Oregon grape root 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. Oregon grape root is an accepted herbal ingredient in major markets, where berberine-containing botanicals may carry conditions; buyers confirm the permitted status, use level and claim for their application.
