Aspergillus is the mold/yeast that is implicated but I suppose there could be other pathogens. I know someone who cured his asthma using medical grade ozone that was put through an olive oil filtering process. It is important that ozone be converted into a less toxic form using the OO (Olive-Oil) filter and you have to use medical grade not a tabletop.
I have no idea how safe inhaling h202 is. I wonder if there is some homeopathic yeast/fungus remedy available. Deseret Biologicals may have something.
