If you have too much fungus/yeast/candida, then of course you'd take ANTI fungals to cure it, yes?
No, you would never kill off all the Candida since it is a natural part of the body. Just like when we take antbiotics we never kill off all the flora nor all the staph bacteria naturally found on the body. The only way to truly treat Candida is to all the immune system to keep in under control. The flora are the primary portion of the immune system that keeps the Candida under control through the production of acids and by competing with the Candida for space and food.
