A natural product made up of fossilized remains of tiny, aquatic organisms called diatoms.

Works like a natural detoxifying agent within the body, killing parasites and viruses that can contribute to illnesses while also helping to clean the blood.

Diatomaceous earth is used in many filtration products because its chemical composition makes it a great filtration aid. It's able to filter very fine particles that otherwise pass through or clog filter papers. This makes it a common product used in water filters to help prevent tap water toxicityand also purification practices for fish tanks.

Additionally, it's also important for manufacturing beer and wine, syrups, sugar, and honey without removing or altering their color, taste or nutritional properties.
A study published in the Journal of Applied and Environmental Microbiology found that diatomaceous earth helps kill viruses and purify drinking water.

A study published in the Oxford Journal of Poultry Science found that DE has the potential to be an effective treatment to help control parasites.

In the U.S., DE is classified under the Federal Insecticide, Fungicide, and Rodenticide Act as a safe substance for household use. It's a natural insecticide, since it absorbs lipids from the waxy outer layer of insects' exoskeletons, which causes them to dehydrate and die of water deficiency. This is why it's useful in food preservation, as a natural home deodorizer and cleanser.

Using diatomaceous earth can help eliminate bed bug, house dust mite, cockroach, ants and flea infestations within your home without the use for harsh chemicals.

A 2007 study published in the Journal of Nutrition Health and Aging stated that dietary silicon is beneficial to bone and connective tissue and helps prevent low bone mass (osteoporosis), which is considered "a silent epidemic of the 21st century." Silica within DE helps with normal bone metabolism and joint formation, with evidence over the past 30 years suggesting there's a positive association between dietary silicon intake and better bone mineral density.

Since it has natural abrasive qualities and kills parasites, DE is used in many toothpastes, skin exfoliators, polishes and skin scrubs. Just like other beneficial clays — like bentonite clay — it dries out harmful toxins and leaves behind clean, smoothed skin with little to side effects.

Diatomaceous earth is also used in many industries. It is used to remove unwanted material from drinking water. It is also used as a filler or to prevent formation of lumps in foods, medicine, paints and plastics, and pet litter. It is used to clean up spills or for insulation in industry, as well as to scrub things. Diatomaceous earth is used as part of various chemical tests. It is also used as an insecticide.
