Has anybody here tried Diatomaceous earth as a chelator?

This seems to dowse OK.

"Diatomaceous earth comes from fossilized shells of freshwater diatoms and is found in vast deposits all over the earth. Made up of silicone and trace minerals, diatomaceous earth can, according to the scientific literature, absorb methyl mercury, E. coli, endotoxins, viruses (including poliovirus), organophosphate pesticide residues, drug residue, and protein, perhaps even the proteinaceous toxins produced by some intestinal infections.

. . . Foodgrade diatomaceous earth binds metals and other toxins, gently siphoning or leaching them out of storage areas and passing them innocuously out of the body.6"
