Yes, when I was doing bowel cleansing\detoxing about 5 years ago.
I take the Terramin or Azomite (volcanic ash feed grade) internally almost daily...
Mix about a 1/4 spoonful in a glass of water and let it sit, drinking the suspension throughout the day; do not stir it up again unless I add more water to it later - then let it settle out again.
Some Native Americans (both north and south) used to eat pinches of clay with their meals...
of course this was for many reasons including nutritional; another of which was due to the lack of refrigeration and food safety... it will help resolve any environmental toxins in the foods... but a small pinch is all you want with meals; and then only with non-organics IMO. Much more than that and you can interfere with nutritional value.
