@Rabbi I disagree, tonsil stones are also a system which the body detox's that requires the body to willing use up some calcium to bind to some sort of toxin in the body. The body willingly gives up some calcium to export a toxin out. So as I said before, after years on the diet and significant detoxification it may be possible that your urine is far less toxic and that your can benefit from for example, the stem cells that are excreted.
