"Sounds like only good can come from it."
Like anything else, it has to be managed. if you to Liver Flushes too often, or without paying attention to cleansing out the bowels (colonics after flushing), or the kidneys ( kidney cleanse tea a la andreas) then you could indeed over or undermanage the situation with undesirable results. i'm a big one for 'sticking to the rules' as written by andreas.... i do colonics after every flush, and i do kidney cleansing tea every 4th flush.
here's what andreas wrote about the subject -
here's the link for kidney tea www.ener-chi.com, under 'suppliers.'
