I talked to the doctor there. I too was wondering how they could do a complete cleansing in a short period of time. He said that if someone is coming from out of state and has a limited amount of time to spend there, they will do the best they can given the time constraints. But it would be much better if the program could be stretched out over a longer period; for the complete rejuvanation program that could be as long as six months to a year. That program costs $5000--that doesn't seem unreasonable at all.
Another thing he said was that their Liver Flush is milder than, for example, the Hulda Clark flush. Which is partly why I asked about watered-down treatments.
