Posted by lily liu Cat's claw, also known as Uno de Gato csp (its Spanish name), is a high-climbing, woody vine that grows profusely in the upper Amazon regions of Peru, Columbia, Ecuador, and other South American countries. At the base of the plant's leaves are two curved thorns that resemble the claws of a cat (hence its name); these allow the vine to climb up trees and other vegetation into the forest canopy. The herb's botanical name, Uncaria, is from the Latin uncus, for "hook." Two species of cat's claw are harvested for medicinal purposes, Uncaria guianensis, used mainly in Europe, and Uncaria tomentosa, commonly imported into the United States. Among the herbal practitioners of South America, the two species are considered interchangeable. For hundreds of years, people in the Amazon basin have used cat's claw to treat a broad range of ailments, ranging from cancer, arthritis, and stomach and liver disorders to skin conditions and even contraception. Traditionally, the herb's primary medicinal form has been a decoction, or crude extract, prepared by boiling the inner bark of the stem and parts of the root. Scientific interest in cat's claw centers on the plant's immune-boosting and anti-inflammatory properties. There is early and speculative evidence that cat's claw may have antiviral and cancer-fighting potential as well. In recent years researchers have identified two separate subspecies of U. tomentosa, which have important differences in their chemical properties. One contains mainly pentacylic alkaloids, substances responsible for the most well-researched effect of cat's claw, namely immune stimulation. The other type of U. tomentosa contains tetracylic alkaloids, which affect the brain and central nervous system and actually counteract the immune-stimulating effects of the pentacylic group.
