As far as I am aware of, all humans have tapeworms from birth to death. As the mother is killed, one of her billions of eggs hatches into an adult and takes over where mom left off. The tape worm lives freely in the intestines of constipated people and when herbs or drugs are used they will hide in the pancreas or brain.
This is why I suggest a weekly dose of the normal herbs known to control parasites and daily use of Olive Leaf and Pure Oregano Oil. These three things are the best we can do on a normal bases, as a treatment, try the Dr. Clark 21 day mop-up program and or the Russian Zappers.
