Cat's Claw
Uncaria tomentosa
Uncaria tomentosa, commonly known as cat's claw, is a traditional medicine used in South American folk remedies. While its specific uses are not extensively documented, it has been traditionally employed for various conditions such as digestive issues and immune support. Scientific evidence suggests potential benefits, including reduced progression of aortic plaque and improved vascular histology in rabbits fed a high-fat diet, possibly through mechanisms involving ox-LDL uptake inhibition and reduced inflammatory responses. Uncaria tomentosa extracts also showed selective cytotoxicity against certain cancer cell lines, with aqueous bark and pentacyclic oxindole alkaloid-rich extracts being particularly promising. Quinovic acid was noted for enhancing KHYG-1 cell cytotoxicity by modulating the Ras/MAPK signaling pathway and increasing interferon-gamma expression. No major safety issues or drug interactions have been recorded, but further research is needed to fully understand its therapeutic potential and safety profile.

Lo que dice la ciencia
- la suplementación con Imoviral® condujo a una upregulación temprana y transitoria de TNF-α e IL-1β, con cambios limitados en otros genes inmunes en comparación con los grupos control.
- Rhi redujo la progresión de la placa aórtica y mejoró la histología vascular en conejos alimentados con dieta alta en grasa al inhibir el uptake de LDL-oxi y disminuir las respuestas inflamatorias.
- Extraídos de Uncaria tomentosa mostraron citotoxicidad selectiva contra algunas líneas celulares cancerosas, con los extractos crudos acuosos de la corteza y ricos en alcaloides oxindólicos pentacyclicos siendo los más prometedores.
- La acidez quinovica potencia la citotocicidad de las células KHYG-1 modulando el camino de señalización Ras/MAPK y aumentando la expresión de interferon-gamma.
