makes sence to me. with out a dought there is some sort of reaction going on with yeast, mold, dust, and maby some others.
the immune system is definatly compromized. when you detoxify your self you become a lot more tolerable(sp?) to the toxins, ( even though yeast may not be a toxin, it can grow and reproduce and compromize normal live and kindney function, well also every other function too, lungs intestines, bowels, brain.
too much yeast isnt a good thing. if your body cant matabolize it and put it to good use.
