I use to collect old medical parasite books. Back about 90 years ago a great book was written that explains each parasite and the disease/conditon it causes. The book was printed 1,000 copies only and peer reveiwed by medical people around the globe and approved.
Many have written that the parasites are the bread & butter of the medical system, you don't kill what makes you $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.
I truly believe a human dies only when he/she is eaten alive and from what I have read, it appears we are up to 85% eaten before the body can no longer support the spirit. This is why I have done everything I could to make the best herbal dewormer I can; once you see these predators killed and expelled out of your body, if you have any sense, you NEVER EVER want these monsters back in your body.
To get worm-free is not an easy chore, you must work for it.
