Cat's claw is a tropical vine clinging to 100-foot (and taller) trees by using its namesake "claws."

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. Ethically harvested cat's claw bark is a major source of income for many Brazilian and Peruvian villages.
