[Renee] We were just discussing silica from DE on another list. Here is a
message that is very pertinent to this, that someone posted. "I just talked
to Dr Galen Knight who conducted the original research on DE as a metal
detox. He also did the lab analysis that appears on Earth Works Health site.
His opinion is that the Silica from DE is not absorbed, does not show up in
hair analysis and that the health claims made as to it being a good source
are not valid. 

---------------------------------------------------------------------

[Annie] I don't know that I agree with all of it. DE isn't sand. It's made
from the skeletons, bones if you will, of tiny creatures. So they can say
what they will, a lot of people taking DE have reported greater bone density
after taking DE for a while. And from what I've read DE is 80% or more
silica. 

======================================

Farmers feed DE all the time to their animals for parasite control and also
to improve the animals' coats.
