Cat’s Claw

Cat's claw is the dried inner bark and stem of Uncaria tomentosa, a woody vine of the Rubiaceae family native to the Amazon basin and Central America. Nustras supplies it as a cut and sifted bark, a milled bark powder and as a standardised bark extract powder, a botanical ingredient used in herbal products.

Cat's claw bark and extract are formulated into herbal supplements in capsule, tablet and powder form, into herbal tea and infusion blends, and into functional beverages and multi-botanical blends.

The material is a light brown to reddish-brown bark powder or extract powder with a mild characteristic odour. Extract ratio, particle size and loss on drying are standardised to specification; botanical identity is confirmed by macroscopic and microscopic examination and thin-layer chromatography, and heavy-metal, pesticide and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies cat's claw bark and extract 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. Uncaria tomentosa is an accepted herbal supplement ingredient in major markets; buyers confirm the permitted plant part, preparation and claim for their application.
