Just try something else for parasites for now. I liked the now foods fresh green black walnut, wormwood, clove tincture. My animals eat large amounts (the goats like 1/2 cup a day sometimes) and only get healthier...but me, I can feel strong effects from 1/2 teaspoon...

Did you ever try bentonite clay? I get the same reaction from bentonite as I get from D. Earth...and bentonite is pretty well known to be safe.

D. Earth is merely fossilized hard shelled sea creatures...its nothing crazy or way out there. It has been used mixed in with grains for quite a while to prevent insects from living on them...so we've eaten small amounts of it probably most of our lives.
