Terahertz is a man-made mineral created by Japanese technology. It has the effect of increasing body temperature, improving blood circulation, thus preventing illnesses and improving health.
Some pronounced benefits are to relieve the "pin and needles" or antbite effects in the fingers, hands and feet. This is largely due to its wavelength in the terahertz frequency, thus helping to prevent clots in the blood stream and enhance blood circulation.
It also helps with balancing against hypothermia. Teraherz keeps balance of human body through stimulating cells, improves hypothermia which causes cold hands and feet, maintains body status and improves cell motility.
