Yes, I do believe that if someone's pH was fully balanced (takes quite a bit of work) then either Liver flushes would be unnecessary (as the body will be in a state to self cleanse/heal and release acidic build up over time) OR that it would mean that less liver flushes would be neccesary .. or better put .. that liver flushes would be more efficient .. and there would be more chance that the toxic waste released from flushing would find their way out/be neutralised.
Of course, the common reason for people to need to do so much flushing is because they either haven't dealt with the emotions of repressed anger, bitterness and resentment, and/or they haven't corrected their diet enough to stop them creating stones. Either of those will keep the liver and gallbladder toxic.
Do you have some reason to believe that you have a non functional ileocecal valve? you can open and shut it manually with palm/finger pressure. do a google on it, there are normally diagrams that show you where it is and how to do it.
What are you working on exactly/what are your health issues? And what have you done so far?
