Two similar alternative treatments that have caused a lot of controversy among
doctors: hydrogen peroxide (H2O2) therapy and ozone (O3) therapy. When they’re given intravenously, both H2O2 and O3 break down in the blood to water and oxygen. This is the key to fighting cancer or any virus or bacterium, for that matter because such pathogens
can’t survive in an oxygen-rich environment. The I.V. H2O2 treatment is quite simple and low-tech, while the ozone treatment is a bit more exotic and technical. Both are
extremely effective, but there is one disadvantage to the ozone therapy: The oxygen has a tendency to bubble and can cause a temporary obstruction (an oxygen embolism) in the brain circulation, which results in an epileptic seizure. Inevitably, this is more frightening for the doctor than it is for the patient since the patient is unconscious temporarily due to the sudden blood circulation blockage. The good news is, it’s not as dangerous as it sounds. The oxygen quickly dissolves, and the patient is blissfully unaware that anything out of the ordinary occurred.
This isn't actually homeopathic medicine -- that's a different modality. Oxygen does kill fungus and bacteria, the hard part is getting it where you want it and in sufficient quantities. You also have to do it more than once, to kill the eggs left behind. Whether it works or not, I don't know.
There are some naturpaths who swear about it.
Theoretically, it should work, particuliarly with systemic bacterial infections.
The problem is that the modern standard involving double-blind studies simply aren't there.
And there is hazard involved, the degree of which depends upon the protocol.
