Uncaria tomentosa
Cat's claw is a tropical vine native to the Amazon rainforest, named for its hook-like thorns that resemble cat claws. It has been used by indigenous Amazonian peoples for over 2,000 years for inflammation, infections, and digestive complaints. It contains unique oxindole alkaloids with immune-modulating properties.
Cat's claw (Uncaria tomentosa) is a woody vine native to the Amazon rainforest, traditionally used for over 2,000 years by indigenous peoples to treat inflammation, arthritis, digestive disorders, and infections. Modern evidence (Level B) supports its use for osteoarthritis, rheumatoid arthritis, and immune support, attributed to unique pentacyclic oxindole alkaloids (e.g., isopteropodine) and quinovic acid glycosides that modulate immune function and reduce inflammation.
The primary active compounds, pentacyclic oxindole alkaloids (POAs), enhance phagocytosis and modulate cytokine production, likely through inhibition of nuclear factor-kappa B (NF-κB) and suppression of cyclooxygenase-2 (COX-2) and lipoxygenase pathways. Quinovic acid glycosides contribute anti-inflammatory effects by inhibiting bradykinin and histamine release. Additionally, proanthocyanidins provide antioxidant activity, while hirsutine may exhibit antiviral effects by interfering with viral replication. These combined actions support immune modulation, reduced joint inflammation, and improved gastrointestinal mucosal integrity.
