Germanium grains rate of 92.1% far-infrared radiation, wavelength 8-10μm, for the human body to absorb optimal frequency and wavelength, far-infrared radiation can deeply invades the human body, the body's absorption of toxic substances and heavy metals and break down, to keep detoxification Yen's role, in addition to far-infrared can resonate with the effect of human cells to form a thermal reaction, so that capillary expansion, the promotion of human blood circulation to relieve fatigue. The main effect of germanium grains:Rid the body of residual waste and heavy metals, so that cell activation, Paiduyangyan and eliminate fatigue, improve sleep quality, and clear the meridians to alleviate a variety of human neuropathic pain, the body wet and cold to ease back and joint pain, expand capillaries, promoting blood circulation, improve human immunity.
