I think you might be using too many different things for your Mum.........you need to stick to one basic method, although I understand you do not want to put all your eggs in one basket. I may not know what I am talking about but....if your Mum is anemic her blood may not have the ability to carry much oxygen so that the ozone will be ineffective. Cancer patients often are anemic from what I have read.
The flax oil cottage cheese diet corrects this problem, and returns the blood to it's proper state. It is worth your while looking into this approach.
