5 Everyday Uses For Food Grade Diatomaceous Earth


It’s hard to believe that there are certain forms of earth made ‘dirt’ which offer an unimaginable variety of health and home-use benefits.

But that's exactly the case with Food Grade Diatomaceous Earth!

Food Grade Diatomaceous Earth (DE), although lesser known than its cousin Food Grade Bentonite Clay, is equally beneficial and useful in its own right!

And even though it's been used for centuries by different cultures, today DE is being recognised and embraced once again for its health promoting powers and should definitely be part of your Self Care routine.

What Is Food Grade Diatomaceous Earth?

Formed from ‘diatoms’ or fossilised phytoplankton, this whiteish, siliceous powder-like substance, at a microscopic level, has a cylindrical shape and carries a negative ionic charge.

These two unusual characteristics are what give DE its many incredible benefits due to the way they attract, trap and carry out of the body positively-charged pathogens, bacteria, parasites and other toxic substances.

Diatomaceous Earth comes in two forms:

  1. Marine Deposits - where salt water was present;
  2. Freshwater Deposits

The marine variety (non-food grade) due to its jagged crystalline structure is not safe to be ingested.

Diatomaceous Earth originating from freshwater deposits however has a finer structure that makes it suitable to be ingested and safer for use around the home.

Health Benefits Of Diatomaceous Earth

Being rich in a naturally forming mineral quartz called ‘silica’ makes Food Grade Diatomaceous Earth beneficial for you and your health.

Silica is a building block of almost everything in nature including rocks, plants, humans and other biological life forms.

A type of silicon, silica is essential for your body and important for the health, growth and strength of your:

  • Hair
  • Nails
  • Teeth
  • Bones


Thanks to its inherent ability to remove heavy metals from water, in addition to its naturally absorbent and abrasive nature, DE is a great tool to use to help internally detox and cleanse your digestive tract and body.

When taken regularly and consistently, DE has proven to be effective at ridding the body of protozoa parasites and certain intestinal worms thanks to its ability to ‘cut up’ these organisms’ cell membranes and killing them in the process.

Control Cholesterol Levels

Studies suggest that taking Food Grade Diatomaceous Earth internally can help lower cholesterol levels and people have reported that they were able to significantly lower their ‘bad’ cholesterol levels to a more healthy level in addition to key dietary changes.

Important Warning: Even though food-grade DE is safe to ingest, avoid inhaling it. Inhalation may cause temporary respiratory irritation such as sneezing, coughing, difficulty breathing, eye, nose and throat irritation or bloody nose. 

Here are 5 everyday uses for Food Grade Diatomaceous Earth...

1. Gut Health, Detoxification & Parasites

DE, when taken internally on a regular basis, can serve to make your digestive system much ‘cleaner’ and healthier.

As it detoxifies and cleanses your digestive tract it also provides you an infusion of essential minerals such as calcium, magnesium, iron and zinc as well as silica.

Mix 1 teaspoon of Food Grade Diatomaceous Earth into a glass of water, stir vigorously and drink on an empty stomach, preferably, first thing in the morning at least one hour before eating, otherwise two-three hours after eating.

Drink an additional glass of water immediately after you've consumed the mix and continue to stay hydrated throughout the day.

Handy Note: The powder will not completely dissolve in the water but it will distribute evenly if you stir it rapidly so that you easily drink the liquid quickly.  Since it won't dissolve, drink as soon as you've finished stirring to minimise the amount of powder settling to the bottom of the glass. It's normal to see a small amount of gritty residue or sediment left behind in the glass once consumed.

Follow this method off and on for a two-three weeks at a time, or periodically for a number of consecutive days, to maximise the ongoing detoxification benefits.

For a more comprehensive 'one-off' detox program to eliminate known toxic metals, medicinal residues or intestinal parasites, follow the same method for 10 days on, 10 days off for 90 days, whilst consuming a diet rich in fresh juices and plant whole foods.

2. Skin Care

By penetrating the pores, Diatomaceous Earth effectively sweeps the dirt residue and dead skin cells, allowing your skin to detoxify and breathe better. 

The mild abrasive quality of DE makes it an excellent scrub and exfoliant for the skin. Despite this slight abrasive feature, its particles are small enough that they do not tend to cause irritation or trigger skin allergies.

Thanks to its fine nature you can use it as a natural face mask and gentle facial exfoliant.

Mix a small amount of DE with distilled water, you can also add a little bit of aloe vera and or raw honey into a paste. Gently rub and smooth all over your face. Leave for 15 - 20 minutes before rinsing off. To maximise the exfoliating benefits wipe off with a warm washcloth using small circular motions.

Note: Avoid contact with the eyes or broken skin.

3. Hair Care

Thanks to its highly concentrated silica, in addition to taking it internally, you can also apply it externally in order to help strengthen your hair, repair damage and improve the health of your scalp.

Add a small amount to your natural shampoo and wash your hair as normal.

You can also make a ‘hair mask’ by mixing D.E. with coconut oil, then lather it through your hair, leave it to sit for about an hour and then rinse out with fresh water.

4. Teeth

Thanks to its slightly abrasive nature, DE will help to give your teeth an extra good clean and help remove stains.

Sprinkle a small amount on to your natural toothpaste or mix it in to your Tooth Powder and brush your teeth as normal before rinsing with water. 

5. Pest Control

In addition to killing parasites, Diatomaceous Earth’s crystalline structure pierces the bodies of many small insects causing them to eventually dehydrate and die. Thanks to its non-chemical and non-toxic nature, it’s a safe and natural alternative to many other commercial pest control ‘sprays’ which often contain harmful chemicals similar to pesticides.

Bed Bugs

Sprinkle DE on your bed as well as any other area you believe bed bugs may be present. Do this every night for about a month to completely kill not just the adults but also possible eggs and babies.


Sprinkle DE all around the house, especially on carpet, rugs, furniture and beds, paces where fleas are most likely to reside. Let it sit for 3 days before vacuuming it out thoroughly. 

You can also try applying DE directly on your pets. Just sprinkle and brush it in to the fur of cats and dogs until it penetrates their scalp. 

Re-apply and repeat the process for 30 days to ensure that the hatchlings are killed off. 

Other Pests

DE can also be sprinkled around the home and in the garden to help control:

  • Earwigs
  • Cockroaches
  • Ticks
  • Spiders
  • Other insect pests

You can use a hand duster or similar to get it into cracks and crevices or wherever you may have infestations.

As a final note, it's important to make sure that any Food Grade Diatomaceous Earth you take internally is totally pure and of a high quality.
