is this news to me that candida can be completely 'flushed' from the body? i imagine this being comparable to eliminating normal flora... it just could not happen.

It's not really cleansing the system to totally flush the yeast out completely. I think the point of a cleanse is just to restore a healthy balance of yeast in the system. There's one product called Whole Body Yeast Balance, and if you check out the link, there is some info provided about what it does. After doing a cleanse like that, it's a good idea to be taking a probiotic on a regular basis, because it helps keep your body regulated (there's actually a probiotic included in the kit as well, but it's a good idea to continue with it after you're done with everything in the kit).

Im not sure I would believe it possible and even if it was how long would it be until the candida recolonise the body?
