Oxidation therapy can be beneficial for candida, but I think it is only one part of the total treatment. You need to bring the body back into balance so candida is held in check through the natural processes the body utilizes. These involve diet and probiotics, but sometimes chemicals can help.
You may want to see if you can contact Dr. John Humiston. I believe he uses Miracle-Mineral-Supplement along with other oxidative therapies in helping people with candida. Since he tracks the results he would be able to give you better information than you can find from other sources.
Another thing to keep in mind is that oxidants work by having a concentration of the oxidant in contact with what you are trying to oxidize for a period of time long enough to complete the oxidation process. With this in mind you need to have a delivery method that puts the oxidant in contact with the candida and need a concentration that is effective with candida. The down side may be that the concentration needed may also damage healthy tissue.
Chlorite is less aggressive than either chlorous acid or chlorine dioxide. With sodium chlorite you have three oxidative chemicals you can use. I think most of the benefits come from chlorite, but it is a little more involved to work with compared to the various Miracle-Mineral-Supplement protocols.
