Green Grace bio-ceramic far infrared Elbow Sleeve is impregnated with 4,000 bio-ceramic beads on mesh spandex fabric which emits far infrared radiation when it comes in direct contact with your elbow which penetrates 1.5 inches (4 cm) beneath the skin. Each of the bio-ceramic beads delivers far infrared radiation to all meridian points located on and around the elbow which will rejuvenate bone cells, reverse inflammation, reduce swelling and pain due to arthritis and improve mobility. Based on Chinese meridian points around the elbow, the bio-ceramic beads will stimulate the pressure points.
