Hi, I am speaking on the phone with my Mom right now. I know very little about ozone therapy, so forgive me, I was just writing about the good results my mother has had. I actually have never even seen her equipment. She just explained to me what she has. She has a regular steam sauna, an ozone generator, and an oxygen concentrator.She has tubing that brings the ozone and the oxygen into the sauna. She explained that she got the rash because she had the sauna on too high, but she learned to adjust it to a much lower setting with experience. As far as ozone in the eyes, She says she doesn't put straight ozone in her eyes. She "ozonates" water with tubing and a flask with I think she said a disposable filter and she puts drops of the ozonated water in her eyes at night due to problems with a chronic staph infection and chronic corneal abrasions. I am certainly not an expert at this, so I am not one to give you advice on how to do anything with ozone, because I actually haven't even seen the equipment. I just know that she has relieved people of chronic conditions including herself with this ozonated water, and sauna with the ozone generator.She even got my Grandpa off v1agra with ozonated water.=0) Good luck and I hope you find the information you are looking for.
