Would devils claw help carpal tunnel syndrome?

Devil's Claw would not be my recommendation in this instance, simply because it's unlikely to be strong enough to deal with nerve pain. It is a tricky condition because it is caused by physical constriction on the nerves in the wrist, but I generally suggest getting more magnesium. You could also try nettle tea or tincture to help reduce calcium dumping/uric acid build-up. It may also be beneficial to consult a cranial osteopath.
