What is Cat’s Claw? (Una de Gato, Uncaria tomentosa)
Named for the hooked thorns on its fruit that resemble the claw of a cat, this South American vine has traditionally been used for its exceptional anti-inflammatory and rejuvenative properties.
There are 34 reported species of Uncaria. The two major species are U.tomentosa and U. Guianensis both of which are known as uña de gato (Spanish for cat’s claw).
Cat’s Claw is one of the best herbs for joint inflammation, notably that associated with autoimmune-related joint degeneration. Autoimmune conditions occur when the immune system fails to recognize the body as ‘self’ and mounts an immune response against it. This results in inflammation and can lead to damage and destruction of one’s own tissues. Cat’s Claw has been shown to decrease tumor necrosis factor (TNF), an inflammatory compound produced by our white blood cells during an immune response, including autoimmune. Reducing TNF can help to effectively limit the inflammation, pain, and tissue damage that it causes.
Cat’s Claw is also a superb adaptogen, an herb which improves the body’s ability to withstand stress, be it physical, emotional, mental, or environmental.
