Cat's Claw is a plant native to Central and South America. It is a vining plant with long claw-like spines that emerge from the vine. 
Cat's Claw is known to be anti-inflammatory and to help quiet the pain of arthritis and other forms of inflammation in the body. It is also a wonderful healer for inflammation of the GI tract.
As always, herbal medicine should be used in conjunction with the care of a medical professional.
