Cat’s Claw has been used in Peru and Europe since the early 1990’s as an adjunctive treatment for cancer and AIDS as well as for other diseases that target the immune system. In herbal medicine today, Cat’s Claw is employed around the world for many different conditions, including immune disorders, gastritis, ulcers, cancers, arthritis, rheumatism, neuralgias, chronic inflammation of all kinds and bowel disorders. Cat’s Claw is a large woody vine that derives its name from hook-like thorns that grow along the vine and resemble the claws of a cat. It can reach over 30 metres high into the rainforest canopy. Cat’s Claw has small, yellowish-white flowers, it is indigenous to the Amazon forest and other tropical areas of South and Central America. There are other species of plants with a common name of Cat’s Claw, however, they are entirely different plants.
