I’ve used Ozone therapy for over 30 years with great success. Many of my patients were sent home to die and ozone, insufflation, autohemotherapy, & dermal application made major improvements in their health & life!. You can run the ozone through olive oil & water in order to breathe it. The water lasts only 20 minutes and you can use it for drinking, enemas, or vaginal douching. The oil lasts up to many years and I’ve used for skin application in infections.
