Newbie with questions!!

Hi

I have severe infestation with several kinds of worms.
Someone here recommended, but I read about it and it says its very dangerous used externally, so using internally seems crazy?? I dont want to scar my colon!

What can I do for worms except Humaworm and Experience and Clear?
Paragone, Clarkia ? L-cysteine, pomegranates? Pineapples?
For how long should I be on these? Should you combine enemas with these? H
