Yes we are here to give people options for different protocols. The body that gets clean will take care of the flora, sometimes people feel weak and I have never had that since I make sure I take the Seasalt .It might be even better to take minerals, but I try not to buy supplements if I don't have to. And I loose often a lot of water since at times I use Epsom Salt and Oxypowder .
Sorry I can't give you a better explanation about the liverflush and the congestion of the liver. This is based on Andreas views and I am making only people aware that there are other views than Clark and Schulze. So may be when they are buying books they can add Andreas Moritz book Timeless Secrets for Health and Rejuvenationhttp://ener-chi.com and read his views. There is a write up on parasites etc.
I personnally for the first 2 years of cleaning I had never done parasite cleaning and only once during a liverflush I saw some liverflukes.
