I can tell you about my experience 2 weeks ago I did the Clark method liver cleanse week without any medication, it only comes from Epson (Saturday) and Biotrohn (Sunday, programs 85/86-89-118).
Intestinal lavage, 1 day before taking Epson salts and intestinal lavages the following two weeks with CDS and BIOTROHN.
I have expelled hundreds of pebbles. I wash every 3 months and Biotrohn I produce many stones...
I am still young without any diagnosed disease, just multiple symptoms. For an older person I would do it in a milder way.
Works! Cds + Biotrohn + liver cleanse
