I think we are settled on the machine that you and your brother got for your mother.
They do know for sure that he has a tumor in the esophagus which has prevented him from eating solid food for about a month now. He is going in to get a stent put in so that he will be able to eat and put on some of the weight he has lost. I think you are right about drinking the ozonated water helping....I had not thought of that.
I am so grateful for the information that you have shared with me! Thank you!
