Firstly, Diatomaceous Earth (DE) is not earth!
DE is made from the fossilised remains of tiny, aquatic organisms called diatoms. Their remains are made of a natural substance called silica. Over a long period of time, diatoms accumulated in the sediment of rivers, streams, lakes, and oceans. Today, silica deposits are mined from these areas.
DE contains about 85% silica which is essential for our bodies. This important, trace mineral is required by tendons, cartilage, blood vessels, and bones. The nutrient even contributes to almost every vital organ, including the heart, liver, and lungs.
