Thanks for your posting. It has always surprise me that we do not routinely worm ourselves and our children just as we routinely worm our animals. I have never had an English GP suggested regular worm doses for the family. Vets recommend worming pet and domestic animals every few months. Many parasites jump the species gap, particularly as our diet is so polluted by chemicals which compromise the human immune system and produce favourable conditions for parasites.[ particularly in the case of liver fluke] Dr Clark has plenty to say on the subject. Love and light Deotima.
