The device uses terahertz frequency to improve the function of cells and molecules in the body. With the use of the iTeracare device, blood circulation can be improved, joint pain can be reduced and skin condition can be improved. Terahertz excites the vibrational modes of water molecules in the cells, which helps to improve the oxygen supply to the cells and remove toxins. Invite you from : Emerald8.
