The best anti-parasitic foods I know of spice wise is fennel seed and anise seed. Pumpkin seeds are
very good, coconut and coconut oil. There is a great anti-parasitic smoothie on a website that includes Tablespoon fresh papaya seeds. one fifth of large papaya,one-fourth pineapple, qtr cup pumpkin seeds, 2 T coconut, 1T coconut oil. Coconut water or milk to blend. Can add 6 fresh cloves, I add teaspoon fennel and anise. Yummy. Finally something kids could take.
They recommend waiting about two hours then take castor oil. The recipe stuns the critters then you flush them out. I like this recipe because I have had times when my critters just got mad and moved somewhere else which makes them ten times harder to get rid of. I discovered inhabitants I did not know I had using this method.
