Cat’s claw is a woody vine native to the Amazon and Central American rainforests. Its name is derived from the hook-like thorns that resemble the claws of a cat. While the research to support many of its supposed health benefits is limited, some evidence suggests that it may help boost the immune system and ease symptoms of osteoarthritis and rheumatoid arthritis.
Cat’s claw bark and root have been used for centuries by South Americans as a remedy for arthritis and to treat digestive disorders such as gastritis, colitis, and stomach ulcers.
It has also been associated with pain relief alongside harsh cancer and HIV medications, including chemotherapy, radiation treatment, and AZT medication.
However, there is currently not enough research to support many of its supposed benefits.
