The Iteracare device is marketed as a terahertz therapy device that utilizes terahertz waves to stimulate healing and pain relief.  Terahertz waves are a type of electromagnetic radiation that falls between microwaves and infrared light on the electromagnetic spectrum.Terahertz waves (THz) sit between microwaves and infrared in the light frequency spectrum, but due to their low-energy scientists have been unable to harness ...   While terahertz waves have been studied for potential medical applications, more research is needed to determine their effectiveness for specific conditions. It is important to consult with a doctor before using any device, including the Iteracare device.  This is especially important for people with any underlying health conditions
