Cat's Claw for Immune Function

Research on cat's claw for immune function is extremely limited in the available evidence base, with the single linked study being a cross-sectional survey conducted in Cusco, Peru during the COVID-19 pandemic that documented widespread use of medicinal plants for respiratory symptom prevention and treatment. Notably, cat's claw was not among the most commonly cited plants in that survey, which focused primarily on eucalyptus, ginger, garlic, and related herbs. Studies indicate that this survey was purely observational and descriptive, making no attempt to evaluate whether any of the plants used were actually effective for immune support or symptom relief. Overall, the current linked evidence base does not provide meaningful data on cat's claw and immune function specifically, and readers should be aware that the broader scientific literature on this topic would need to be consulted to form any substantive conclusions.
