Cat’s Claw

Cat’s Claw
Cat's claw or cat's claws (also uña de gato or unha de gato in Spanish or Portuguese)

Straight from the Amazon rainforest, Cat’s Claw is naturally derived from a vine known as Uncaria tomentosa. Its primary use is not for memory or concentration but rather for conditions such as osteoarthritis and rheumatoid arthritis. It is one of the most popular herbs in the United States and is used to treat a variety of conditions beyond those already listed.

In addition to these primary uses, cat’s claw is well-known for its ability to stimulate the nervous system, enhancing the body’s natural ability to combat environmental stress that often causes cell damage. By repairing the brain and body’s cells in this way, cat’s claw improves brain health and cognitive performance, especially as people age.
