I think it is used as a way to sell something aswell Charlie. It seems to create a drama around the ability to heal. Possibly like a milestone a person hopes to reach... they know that they have reached certain steps to thier healing.
But I believe have experienced something of a crisis... the thing called die-off when it comes to candida. However it could have been something else aswell, not really sure. But what it felt like was extreme brain fog, fatigue, and shortness of breath. I do know this though, the candida was no where near as bad after that happened.
