This reviewer praises it:
I have read extensively that farmers use this to give their animals shiny coats and good digestive health. If it works for the animals, it should work for humans too I thought. I started using D.E. and followed the directions, starting slow. I went from a teaspoon to a tablespoon within about 6 weeks. Once I got up to higher doses, which I just drank in water, I did really notice a difference in the health of my skin. It became so much softer and less dry. I have always had really dry skin and eczema, and this really did help. D.E. in layman's terms are essentially microscopic one celled plants. Magnified, they are all spiky looking, and basically act like "pipe cleaners" when they pass through our intestines. They help slough off stuff we don't want in there, and that is how they benefit our digestive health from the inside out.
