I have also found a lot of obtuse doctors, and labs. I once sent my stones to a large lab here in Rio de Janeiro, and it came back "fecal matter". I called and made a fuss... did you actually charge me to tell me this? Are you kidding? You didn't even bother to analyze it?
My dad, however, sent his to another lab, and got the usual results, bile, cholesterol crystals, etc.
There is no question the liver cleanse is fantastic, it works!
