Ozone machine we had is an industrial one and it is only something you can breathe in for like 15 minutes it irritates your lungs... I think what you might be searching for is Ozone IV's which is IV administered at the doctor office. You need a medical professional. But will the kill the type of parasite you have?
My ND did OZONE IV's and he put me on anti-parasitic, and diflucan which really made a big difference. It might be wise to consider an infectious doctor or look up Dr Klinghardts, Mimosa Pudcia protocol. Also there is a parasitologist my ND sent all my sample to he is Arizona that is Parasitologist Dr.Omar Amin at the Parasitology Center Inc. A world renowned parasitologist receiving parasitology research scholarships, awards, honors.
you can look him up maybe he can shed some light on what step you should take
