Uncaria guianensis, Una de Gato, Cat's Claw. The Piura Indians used a bark decoction of U. guianensis to treat inflammation, rheumatism, gastric ulcers and tumors, and as a contraceptive. Indian groups in Colombia and Guyana use it for dysentery. The "claws" are much more strongly curved than those of Uncaria tomentosa.
