Square Shooter, The " Cat's Claw " that is in the herbal mixture, is from the South American Cat Claw herb. It is used for inflammatory arthritis, and stomach ulcers. So that could be why you are felling better.
It is also a climbing vine, and has claws that hold it to the trees and such. They use the bark from the vine. It is also used for cancer treatment, immune system, and gout. It is known down there as " Una De Gato " They put a little lemon juice in the teas, or tinctures, to release the tannins. It is a great immune booster. What I have read about it says a small amount can increase the immune system by fifty percent. In Europe it is a prescription only supplement. Just don't let the FDA find that out, it will be banned here, because it is effective, and the Drug Companies can't patent it.
