The Liver Flush is not particularly designed to kill flukes. Flukes will come out incidentally. The flush is designed to push stones and other debris out of the liver and gallbladder. The flush can be exhausting for the body so as well as waiting for the stones to move forward, the recommendation to wait 4 weeks is very worthwhile so not as to burden your system, unless you are having a crisis where a stone is stuck and you really need to flush. Its like having an operation... you need to let the body recover.
