I don't know about what to believe since they also have a book about curing HIV, rigth there I boubt every other claim,and would chose not to do what those book say.

One of their instruction is : add two drop of HCl (Hydrochloric acid) which makes sense since a lot of medicine have it in their somehow as part of their ingredients.  We already have HCL in our stomach.  But playing with concentrated HCL can be dangerous and they should at least warn the public.

Some staff make sense,and other staff hasn't been proven scientifically, which make the whole book kind of unreliable.  I think.
