I can remember learning in Jr high Science class that having hookworms was uhhh pretty much not a good thing
besides if we have residing in us parasites that have formed a symbiotic relationship thru out our evolution which we do have(they would no longer be parasites), furthermore, they would not be wiped out by these herbal treatments etc.
