Cats Claw – Herbs For Alternative Medicine


Cat’s Claw is a tropical woody vine that grows in the rainforests and jungles of Peru. Some cultures refer to the plant as the ” Miracle Herb from the Rain Forest “. This vine gets its name from the small thorns at the base of the leaves, which looks like a cat’s claw. These claws enable the vine to attach itself around trees climbing to heights up to 100 feet.
