Overview

Cat's claw is a vine that grows in the rainforest in South and Central America. The two most common species are Uncaria tomentosa and Uncaria guianensis.

Cat's claw root and bark contain chemicals that might stimulate the immune system, kill cancer cells, and fight viruses.

People use cat's claw for cancer, osteoarthritis, rheumatoid arthritis (RA), viral infections, and other conditions, but there is no good scientific evidence to support any of these uses. There is also no good evidence to support using cat's claw for COVID-19.

Don't confuse cat's claw with cat's foot or devil's claw. These are different plants.
