I know I tried to do the Dr. Hulda Clark liver flush the way she recommends and I failed three times. I wasn't aware that you were supposed to DEWORM for six or seven days prior to the actual liver flush.
Once I came to MH's forum, then he explained that the gallstones are blocked by parasites. At first, we can't know for sure if this is true or not, since most of us are not biologists or doctors. What we do know for sure is what gets us results.
And I (and others) can testify that this works once you follow the PROTOCOL. As a rule of thumb, if an herbalist or healer tells us a certain method and it can be duplicated - then we can say that the method honestly works.
