Cat's claw (Uncaria tomentosa) contains oxindole alkaloids and quinovic acid glycosides that suppress TNFα production and inhibit NF-κB activation in inflammatory pathways. Proanthocyanidin B2, the main bioactive compound, demonstrates the highest molecular binding affinity at -9.2 kcal/mol.
Reported Benefits (Provisional)
Origin & History
Cat's Claw (Uncaria tomentosa) is a woody vine native to the Amazon rainforest and other tropical regions of Central and South America, thriving in humid, well-drained soils. Named for its hook-like thorns, the inner bark and roots are prized for their medicinal properties. It has held profound significance in indigenous cultures of Peru and Brazil for centuries, often considered a sacred plant in traditional medicine.
Research Narrative (Provisional)
Numerous in vitro and animal studies, alongside some human clinical trials, have highlighted Cat's Claw's antioxidative, immunomodulatory, and anti-inflammatory actions, particularly for joint health. Emerging research also investigates its neuroprotective effects and potential role in supporting DNA repair mechanisms, validating its broad traditional applications.

Nutritional Profile
- Oxindole Alkaloids: Stimulate immune function and support neural health. - Quinovic Acid Glycosides: Provide anti-inflammatory and antiviral properties. - Polyphenols and Flavonoids: Offer potent antioxidant protection against oxidative stress. - Triterpenes: Enhance liver detoxification pathways and contribute to cellular regulation. - Proanthocyanidins: Support cognitive clarity and skin health. - Minerals: Contains calcium, potassium, and magnesium, supporting bone, muscle, and cardiovascular health.
Reported Mechanism (Provisional)
Cat's claw's non-alkaloid fractions suppress LPS-induced TNFα production in RAW 264.7 cells at concentrations of 0.001-1 µg/ml (P < 0.01). The primary mechanisms involve inhibition of NF-κB activation and reduction of IL-6 inflammatory cytokines, while oxindole alkaloids like speciophylline demonstrate strong molecular binding affinity (-8.1 kcal/mol). Proanthocyanidin B2, the main bioactive component, exhibits the highest docking score at -9.2 kcal/mol.
Clinical Narrative (Provisional)
Controlled clinical studies have demonstrated pain reduction in patients with chronic inflammatory disorders, though evidence remains limited and varies significantly by preparation type. In vivo studies have reported decreased IL-6 and NF-κB levels, improving chronic inflammation parameters in research by Aguilar et al. (2002) and Sandoval et al. (2002). Current clinical evidence is insufficient for definitive anti-inflammatory conclusions due to preparation-dependent variability and limited human trial data. Most supporting research consists of in vitro and animal studies rather than large-scale human clinical trials.
