one should never undertake any detox regimen without first making sure the channels of elimination are open and freely flowing. you have simply reabsorbed the toxins as soon as the liver released them.
kidney and bowel cleanses are first. then parasites. then the liver.
i highly recommend both the kidney cleanse and the Lower Bowel Balance formula from the barefoot herbalist. i have used both with amazing results. the kidney cleanse worked quickly, but it takes a while to recondition a sluggish and toxic gut. after 8 months of LBB taking 8 capsules a day on the average, my guts have been working fine ever since. its been 2 years now. the key is to take enough per day(you may need more or less than i) and take it faithfully for a long enough period of time. 9 months to a year are normal.
once the bowels are flowing using the LBB then you can make the next steps. dont stop the LBB though. everyone wants a quick fix and get in a hurry or stop after a couple of months and have to start taking them again and say they are hooked now. big pile of BS. it takes time to turn around a lifetime of wrong living.
