Cat’s Claw

Summary and Conclusion: Cat’s claw

• Rosenbaum’s literature review on use of Cat’s claw in osteoarthritis found one study which resulted in significant improvement in pain on activity, overall pain and overall physician pain assessment compared to placebo, but no significant differences were found for pain at rest or for pain at night. The review outlined another study which evaluated glucosamine sulfate (1500 mg daily) vs Reparagen (1800 mg daily), and both agents resulted in about 20% improvement of pain scores according to the Western Ontario and McMaster Universities Arthritis Index (WOMAC) in most subjects of both study groups. Reparagen capsules contain 300 mg Vincaria, a patented extract of Uncaria guianensis, (Cat’s Claw) with 1500 mg Lepidium meyenii, a vegetable from the Andes Mountains with IGF-I activation potential.
