This easy-to-maneuver pad provides up to two hours of hot relief. By using heat, this pad is ideal for stimulating blood circulation to the brain and for providing relief from ailments that include tension, stiffness, headaches, and chest pains. To use it as a cold compress, place the PCH pad in the refrigerator for 2-3 hours until thoroughly chilled. It can then be applied to painful, swollen, or injured areas throughout the body. Its versatile design may be applied to any part of the body, although it is custom-designed to be worn around the neck and shoulders. To reuse after heating, wrap the pad around a cloth and submerge in a pot of boiling water. The pad will turn clear once all crystals are dissolved. This indicates that it is ready to be taken out of the water and cooled. Once cooled, it's ready to be used again. After use as a cold compress, chill the pad in the refrigerator until ready for use again. Do not place the pad in the freezer. Your browser does not support JavaScript.
