My response is two-fold:
1) What is "basic H"?
2) I heard from a reputable source (she is very much into the "natural way")that DE does not work when given orally for internal parasites. She has tried it with her LaMancha goats and measured her success with fecal testing that she performs herself. She gave them DE at the appropriate doseage and saw little/no decrease in parasite population. The reason she gives is that the way DE works is that it works by drying out the bugs you are targeting. Basically, they die of dehydration when the DE cuts into their delicate exoskeleton. You can check on this by looking at www.fiascofarm.com
