Diatomaceous earth is a naturally occurring sand extracted from the earth.
It consists of microscopic skeletons of algae — known as diatoms — that have fossilized over millions of years .
There are two main types of diatomaceous earth: food grade, which is suitable for consumption, and filter grade, which is inedible but has many industrial uses.
The diatoms in diatomaceous earth are largely made up of a chemical compound called silica.
Silica is commonly found in nature as a component of everything from sand and rocks to plants and humans. However, diatomaceous earth is a concentrated source of silica, which makes it unique.
Commercially available diatomaceous earth is said to contain 80–90% silica, several other trace minerals, and small amounts of iron oxide.
