Bowel cleanse is nothing to be scared of. It is something easy and very good. You can try with Oxypowder first. Later you could try something like Psyllium and Bentonite shakes. Very easy.
Bowel cleanse will help you with Body Odor . It has helped me a lot.
for a better liver flush, try to drink apple juice for 6 days before the flush. This soften the stones.
If you did not get stones, it means you need to soften them before the flush.
