Cat's Claw (Uncaria)

Cat's Claw (Uncaria tomentosa) is a woody vine native to the Amazon rainforest, where it has a long history of traditional use for a variety of health concerns. Research suggests that compounds found in its bark, including oxindole alkaloids and polyphenols, may support immune function and contribute to anti-inflammatory and antioxidant activity. Studies indicate potential benefits for joint comfort, with some clinical trials showing modest improvements in pain and stiffness associated with osteoarthritis and rheumatoid arthritis. Preliminary research has also explored its role in supporting digestive health and protecting cells from oxidative stress. While findings are promising, much of the evidence remains early-stage, and the quality of extracts can vary considerably between products, making it worth exploring the available literature thoughtfully.
