I read in the Liver FAQ at the bottom of this forum that the tan stones are from the gallbladder, so that may be a good thing for your digestion. During my recent flush, I had about 200 tan small stones. If the info is correct then pretty much all of my stones came from my gallbladder, which I hope will benefit my digestion which was a bit off for a while.
BTW, for people suffering from candida, like myself, apple cider vinegar may be a good alternative before a flush.
