They are applied lukewarm on the skin to help soothe neck, shoulder, elbow, lower back, belly, knee stiffness and discomfort. The moxa cone is mounted on a large candle base to create a thermal buffering zone. A ventilation hole runs through the moxa stick and the base, allowing smoke to draft downward and support heat therapy. Simply peel off the backing to expose the self-adhesive base, light the tip of the moxa, and apply directly to the skin. It adheres well, stays securely in place, and is easy to remove. The moxa rolls can be used on acupoints of the knee, shoulder, elbow, belly, and back.
