It's just new to the website - I have been making it for years along with a lot of other formulas that are not on the website. It works a bit differently because the yeast has not been exposed to the natural chemicals in the herbs - this is what will kill them.
The herb blend also kills them from all over the body - not just on the surface or in the intestinal tract. This helps remove the spores so they won't be able to reproduce.
Diets that are supposed to "starve" the yeast by not feeding them just do not work for the long term. The key to getting candida in check is to kill ALL of them at the same time - then let the body rebalance itself.
Another thing that is very important is trying to figure out WHAT caused that yeast overgrowth in the first place. If it was from overuse of anti-biotics - then it is pretty easily fixed if the anti-biotic use is done. But if it from parasites - then the parasites have to be removed first followed by the excess yeast.
