Cat’s claw, Uncaria tomentosa, is an herbal extract. It has been used traditionally in Peru for over 2,000 years. Alkaloids, phenols, sterols and glycosides comprise some of the naturally occurring constituents of this herb.

Joint Health: In a 52-week, randomized double blind trial, cat’s claw extract promoted joint comfort in volunteers. A 4-week study also suggests that cat’s claw has the ability to promote joint comfort, in part by moderating prostaglandin metabolism. Other mechanisms of action that may account for these effects include modulation of both oxidative stress and cytokine production.

Cardiovascular Health: Cardiovascular protective properties include support for healthy vascular and platelet function.

Immune Support: Cat’s claw alkaloids have been specifically associated with enhancing immune system cell function, including phagocytosis and macrophage activity.

Gastrointestinal Health: Studies involving cultured gastric epithelial cells suggest that cat’s claw may provide important antioxidant protection for gut health.
