I was drawn to Andreas Moritz "The Liver and Gallbladder Miracle Cleanse" - you could get that book. He doesn't address parasites because he says that once you begin the process and flush colon, liver, etc. parasites can't continue to survive in a healthy environment. I found it too complicated to deal with parasites on top of the flush. I did not release many stones the first cleanse. But the next 2 - good release.
