Intra Nasal Laser uses Light Therapy to Stimulate Your Immune System. Using Laser and LED lights for healing isn't new.However this device delivers healing laser or led light to the nasal cavity which is close to rich veins and "treats" your blood stream.Don't dismiss this method because of lack of USA studies. Low level light therapy has been researched by NASA for several years and has demonstrated the ability to alter, and improve, cellular function.There are many studies supporting the method in China. At first glance the intranasal laser might look odd futher study should change youir mind.
