Cat’s claw is a tropical vine clinging to 100-foot (and taller) trees by using its namesake “claws.” This herb is very effective and traditionally used for relaxing the body.

Cat’s claw (una de gato in Spanish) refers to at least 20 plants with sharp curved thorns, both native to the South and Central American tropical rain forests, with most of the commercial production focused on Uncaria tomentosa.
