Question on if there are studies for the liver flush ..GM ans… very kind of you. sorry it took so long to reply. I have had 11 flushes now with thousands of stones. the overall improved life has been the biggest change in my health. two fold answer… you can look on the authors website there are studies there, also in the book. keep in mind that no study proves anything except human clinical trials published in Pier reviews journals. these cost million plus to do. healing the body naturally is not very profitable for any busiess pay for these. it’s really yours for the taking, I ask myself what did I have to lose?
