A friend of mine had a severe lung infection (both lungs), was treated with old bad "A"-stuff for months, with no positive results. It was getting worth actually, probably because it was of a yeast nature.
I've convinced her to do colon cleansing.
Boy, she had all sorts of living things coming out of her, - the whole Zoo.
4 weeks later, when she had her catscan done and went back to the doctor, he went speechless. The infection was gone.
