Jim Humble seems to think it will help HIV. You must have seen this in his book. I wonder about this. I think it is a virus. Chlorine dioxide will not cause the virus to mutate; and should destroy it. I remember reading a report about an AIDS patient intravenously receiving sodium chlorite activated by lactic acid. I heard no follow up.
Did you teach the guy how to use it; or are you waiting to see how he accepts the literature? He might have difficulty with the activator, if he is homeless.
