Terahertz is a man-made stone that emits far-infrared and negative ion energy. The far-infrared energy helps promote metabolism, improve blood circulation, and ease muscle pain, stiffness, and inflammation. The negative ion energy aids in protecting the body from harmful radiation, pollutants, and electromagnetic smog when worn. As Terahertz revitalizes inner energy flow and enhances circulation in the skin, it is said to slow down the aging process and help one appear more youthful. Terahertz improves mental clarity, aiding one in organizing and processing complex information.
