Frank,

you might try to eat Papaya _seeds_ or shrimp and prawn-like seafood. They
have helped several of my friends  against parasites. One didn't even know
that he had worms until a whole bunch of them came out after a shrimp meal.
All people were drawn by their nutritional instinct to these foods --
they tasted them very delicious. You might try (smell) other herbs as well
or read a herbology (phytotherapy) book.
