I studied all of these things 10 years ago, we humans are host to 20,000+ parasites and thats just the BIG ONES!!!!!!!!!!!!!! We live on the bottom of an ocean of air in the cess pool of parasites. Many a Breathairian headed to the mountain tops to escape the diseases of living at the bottom of it all.
Thats why I took so much interest in herbs that aid in parasite control.
