I just tried it and it seemed to be making the big creatures very tired or something cause they were not moving around for a couple of days. I have a very larg load in my intestines since way back so can´t tell if anything died, although I think something did. I did another liver cleanse afterwards and enema in case it would be too toxic. I used it for 150 kg the first time and second time for 300 kg just to see if a larger amount would do any difference, at the same time didn´t want to try too much in case of side effects. It only kills adult Tapeworms though so there might be a risk of eggs hatching and becoming larvae fast I´m guessing so you probably need to use herbs or other medication as well. It also only works in the intestinal tract. Praziquantel works outside the intestines and also supposedly kills larvae from Tapeworm as well.
