The infrared light that is emitted by our bodies via body heat is reflected back into the body from the patch in the form of infrared energy. When the patches are placed on the meridians of the body or the acupressure/acupuncture points the light is conducted efficiently. The meridians connect and vibrate at their own frequency of their own energy pathways. The patches are reflecting our light but on the basis of allowing the current energy ' clog' from stress, pain, anxiety, inflammation etc. to be removed by the body with the help of the patches. With continued use and proper diet , the free radicals can be removed as waste from the body. The glutathione patches help to build up the natural glutathione and therefore allow the body to remove the waste products more efficiently and reduce the free radicals.
