I've never heard of this stuff before. It's an anti-tick dewormer for cows. you can put it in their feed and it does all sorts of good things to them. It shares the same chemical chains as sand, but is derived from diatoms - anchient precursors to shellfish - aka plankton.
There's not much research out there on the impact of plankton on human diets. But I found a paper:
I think this fossilized version is just the same stuff silica microchips are made from.
It's good for humans, too. I might just buy a bag and try using it for a detox program.
