Flukes can be difficult to kill off and also there are quite a few different species of flukes that can live in humans. It is also easy to become re-infected by eating contaminated undercooked meat or fish. It is also very likely that you have some other parasites. It sometimes takes several to many treatments with herbs or drugs to kill the flukes off
H. Clark's three herbs seems to be effective against flukes but it is only the first step in her program to improve health. There are several of these healing programs at the Liver Flush Support Forum . Before your flukes are finally gone you may need to improve your immune system and digestive system, do detoxifications to get toxins and pollutants out of your body and learn how to protect yourself from reinfection.
The next step would be to do the preparations and then do Liver Flushes. The only time I've seen flukes come out is when I've done Liver Flushes after doing a parasite treatment.
