ozone is o3 it is slightly caustic. in america it is mostly mixed with own blood and heparin or bubbled thru saline water . it does lyse bacteria and other pathogens but it also lyses red blood cells . as borrelia is 3 phase it will not kill encysted lyme hiding in biofilms and areas of low blood flow . and a a couple hundred a iv one must weigh the options . one could purchase a longevity medical grade machine and get o2 tank and have it for ever with a few thousand dollar investment. insufflation in my ears and nasal definitely helped.
