I have read some of the posts on Andreas Moritz ' forum,
and from what I can tell he seems to think the colonic part is very important because stones can get stuck in the colon and are re-absorbed back into the body if they are not eliminated. I think he says this can result in bad complications. I don't know what others (like Hulda Clark , etc.) say about this though, and of course I can't speak for Andreas. You might want to post your message on his forum and see what he says.
