Uncaria tomentosa is also called “cat’s claw” and “claw vine,” and it refers to more than 20 different species native to Peru and surrounding rain forests. Uncaria tomentosa is called Cat’s Claw because the hooks of the plant resemble a cat’s claw. Uncaria tomentosa, or Peruvian Cat’s Claw, is used for infections, wound healing, and immune system health. Uncaria tomentosa, or Peruvian Cat’s Claw, has a variety of alkaloids and other compounds that research has shown to be beneficial for reducing the occurrence of lung infections, boosting the immune system, and reducing inflammation.

Not to be confused with the Chinese Cat's Claw which aids in the rebalancing of the nervous system, Peruvian Cat's Claw has been found especially effective in revitalizing and enhancing immune system activity. Studies from South America have reported some effectiveness against cancerous tissue, and it appears especially important and efficacious when chemotherapy has been previously applied.
