This is because ozone is O3, or 3 atoms of oxygen, and it quickly breaks down into O2, or the oxygen molecule that we breathe. So it's able to flood the body with oxygen, which can have anti-inflammatory effects, kill pathogens (viruses, bacteria, fungi), boost energy, and even stimulate some tissue regeneration.
Because of this, some people drink ozonated water for health benefits (as we do on occasion). This can be made by a water ozonator like the one we use.
We should point out ... a water ozonator is not a health device. It can produce ozonated water for a variety of uses like cleaning food and cleaning the home. It's just that some people choose to use it for drinking water too. We always recommend you research this topic before doing so and determine if it's right for you.
In any case, medical doctors who choose to use ozone therapy don't have you simply drink ozonated water. They actually inject the ozone. And while we've heard that this is more common in Europe, there are some non-conventional US-based MDs like Dr. David Brownstein who provides this service, and his new book, Ozone: The Miracle Therapy, talks about the many benefits. Follow that link to see x-rays of a patients joint repair that was entirely the result of injected ozone. Surgery avoided.
Sorry, but one more link over to Amazon in case you want to see Dr. Brownstein's other books. The one he promotes most often is the one on iodine, and we agree that this is one topic that's not understood widely enough. But the new ozone book can only be found at this time on Dr. Brownstein's site.
