Wikipedia states: "Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae." It is unlikely that it was farm raised. Dan "Diatomaceous earth (pronounced /ˌdaɪ.ətɵˌmeɪʃəs ˈɜrθ/) — also known as DE, TSS, diatomite, diahydro, kieselguhr, kieselgur, brand names include Celatom or celite — is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to off-white powder, with a particle size extending from less than 1 to over 100 microns, but typically around 2 to 10 microns. [1] This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity. The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron. "Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide, as an absorbent for liquids, as cat litter, as an activator in blood clotting studies, and as a component of dynamite. As it is also heat-resistant, it can be used as a thermal insulator." -- The Silver List is a moderated forum for discussing Colloidal Silver.
