Pain-Rx incorporates a blend of 10 herbal extracts, many of which are being newly introduced to the dietary supplement industry by Hi-Tech Pharmaceuticals with the introduction of Pain-Rx. These ingredients have a proven track record of efficacy over centuries of use in traditional Mayan Indian medicine. Pain-Rx is a unique COX-2 inhibitor because, while it inhibits the "bad" COX-2 enzyme, it does not interfere the action of the "good" COX-1 enzyme, which means Pain-Rx has the unique distinction of being a selective inhibitor. Pain-RX is "quick-acting" and provides benefits with the very first use.
