When I did my first liver flush, I just jumped right in with that one. As I learned more about cleansing, I did the Bowel Cleanse using Bentonite clay and have completed several. The same with the parasite cleanse. My suggestion would be to read Dr. Clark's book..... The Cure For All Diseases " and 90% of it is right here on Curezone, so you can read it for free. ALWAYS listen to your body. It will tell you what it needs if you take the time to listen.
