I personally think going with stuff thats not way too harsh is the best. Raw Garlic, Raw Ginger, Coconut Oil, bentonite clay, bromelain, pumpkin seeds, etc...

If you can find food grade diatamaceous earth I would highly recommend that as well.

Parasites just can't thrive in a healthy digestive tract, so do whatever you can to get your digestion in check and don't overeat. Eat the best healthiest foods you can and don't eat too many carbs.
