I took DE for about 45 days, 1-4 tbsp twice a day.
Didn't do daily enema and regular Liver Flush as wasn't aware about doing these during parasite cleanse process, though should have done these. Though one must be careful before starting Liver Flush as Liver Flush without parasite cleanse could scatter worms in body.
DE only works in intestine but parasites could be all over the body (brain etc.)
The advantage of DE is it acts mechanically.
I no longer use DE and went back to the usual Black-Walnut , Wormwood , clove etc. protocol.
