I'm not going to pass judgement on whether one can or can't do a Liver Flush without first doing a parasite cleanse, but I will simply draw your attention towards Doc Sutter's assertion that attempting to flush the liver whilst it still has live parasites and viable eggs in it may lead to redistribution of these ova in the body (possibly returning back to the liver) and thus flushing may be a waste of time until one has taken steps to avoid such an ova-redistribution scenario occurring. You'll find Doc Sutter has a dedicated forum on Curezone.
At the end of the day, it's your decision.
Good luck!
P.S. can't believe this thread is 8 yrs old and counting!
