My view always has been that the green ones are mainly cholesterol and bile. So I never thought they were calcified stones. Andreas has said when you get the black chips they are part of calcified stones. Also often white stones can be calcified.
Most people here do cleansing for general health, for symptoms that could be gallbladder problems, allergies etc.
To me it is obvious that a clean liver has benefits for your general health.
I am a good example of that //www.curezone.org/forums/m.asp?f=337&i=11922
As far as my 1 calcified stone (24mm) I still have it after 2 years of flushing. But since my liver and gallbladder has been cleaned from other sludge all symptoms are gone, inflammation disappeared and the gallbladder wall is back to normal from 42mm to 3 mm and the stone that started it, because of being stuck in gallbladder neck, is now free floating.
