I've successfully killed parasites (but also along with taking the herbals also) with the recipe in the book of Sandra Cabot's "The Liver Dr"--Raw Juices can save your life.
I'ts not one I'd recommend for the pleasure of the taste of it- but worms hate it.
Cabbage/spinach/ginger root/2 cloves of garlic- more if you can handle it/apple/pomegranate juice. I guess if you were tougher than me, you could throw in the hot peppers.
