Tell your kids it’s “skeleton powder.” Or that it slashes and dehydrates bugs to death! If you have boys especially, they may look at your natural pantry with a whole new respect!

You won’t be lying  … Diatomaceous Earth (or DE for short) is all that and more! Here are all the (not so gory) details on this natural remedy wonder for anyone with pets or a family.

What Is Diatomaceous Earth, Anyway?

DE is, as mentioned, a white powder naturally occurring from the fossils of diatoms (a type of algae found in river bed and lake beds). The diatoms form a very hard shell of silica in a tubular shape.

When dry, Diatomaceous Earth appears very fine and soft to the naked eye but microscopically it has some very unique qualities:

  • High Silica Content: These fossilized diatoms have a very high silica content (which is used to build hair, skin, and nails).
  • Hard as Nails … or Diamonds: DE is very hard (only two points lower than diamonds on the hardness scale). It looks like a tiny cylindrical tube with many holes in it when viewed through a microscope.
  • Holds a Strong Negative Charge: DE has a very strong negative charge, which makes it purifying and beneficial in several ways.

Since the 1960s DE has been commonly used in things like toothpaste, as an anti-caking aid, for clarifying beer or wine, and to eliminate pests naturally. In fact, you’ve likely consumed products that contain traces of DE without even knowing it! While I’m usually not a fan of hidden ingredients, DE is one we don’t need to worry about.

That doesn’t mean it doesn’t have its share of controversy … not all of it warranted.

How Do I Know DE Is Safe?

In this article, I’m referencing Food Grade Diatomaceous Earth, which the FDA classifies “Generally Recognized As Safe” for human consumption, even when pregnant or nursing. It is NOT the industrial grade type used in pool cleaning. Much of the misunderstanding about the benefits of DE stems from the difference in these two types. The industrial grade is toxic to humans and should be avoided. It is also toxic to workers who collect it.

Food-grade Diatomaceous Earth is purified and amorphous, not crystalline. It is inert and harmless (as long as you’re not an insect with an exoskeleton).

What Does Diatomaceous Earth Do for the Body?

For the human body … and even for animals … DE is an ally. Thanks to its strong negative charge diatomaceous earth binds to unwanted toxins in the digestive tract. On the skin, it acts as an oil binder, a purifier, and an exfoliant.

For unwanted bugs and insects, it’s quite another story.

Does DE Kill Insects?

In a word, yes! Many use Diatomaceous Earth as a natural pesticide. Its sharp and strong structure allows it to puncture and drain the exoskeleton of insects from their protective fats and oils on a microscopic level. This causes them to dehydrate and die (while humans and animals are left completely unharmed).

10 Ways to Use Diatomaceous Earth

Uses for diatomaceous earth-skin hair and nails-pest controlSome sources claim that DE is a cure-all for everything from parasites to viruses and everything in between. They claim it eliminates free radicals, remineralizes bones, and halts aging in its tracks.

I haven’t found any research to back up these claims, but there are studies on silica and other compounds found in DE. These are the benefits that seem credible based on the available body of evidence:

1. As a Natural Alternative to Pesticides

Most pesticides and insecticides work by poisoning the pest. Unfortunately, chemicals that are harmful to small pests can also be harmful to humans and carry risks. Insects can also develop immunity over time.

DE works mechanically on:

  • fleas
  • bedbugs
  • cockroaches
  • ants

Just sprinkling a little DE around the house bonds to and absorbs parts of the waxy coating on the exoskeleton of these insects, causing them to dehydrate and die. Sprinkle a perimeter around the exterior of the house and also indoors where problems are observed.

The Federal Insecticide, Fungicide, and Rodenticide Act classifies DE as safe for household use. The Environmental Working Group classifies it as safe for household and beauty use as well.

2. To Treat Fleas on Pets

I will be forever grateful for DE and its help when we had a horrible flea infestation. We adopted a rescue kitten and she brought along a few thousand close friends … FLEAS.

The fleas quickly infested the entire apartment we were living in at the time and with a new baby and toddlers, it was a HUGE problem. I didn’t want to use any type of harmful pesticide either since my kids were crawling around on the floor.

To stop the flea outbreak, we sprinkled DE all over our carpet and soft surfaces several times a day. The only potential concern with DE is irritation from inhalation, so I wore a dust mask when sprinkling it around the whole house. I worked the powder into the carpets and let it sit for about an hour. Then, I vacuumed it up. I repeated this a few times a day for 4 days until the fleas were gone. (Yes, this is a messy process!)

We also killed the fleas on the kitten by carefully dusting her with DE a few times a day, avoiding the eyes and nose.

We now dust all of our animals with DE before and after going hiking with them in the woods, or if they show any signs of fleas.

3. Fighting Bed Bugs

Were you hoping bed bugs weren’t real? Well, sorry … they definitely are and don’t discriminate against even very clean homes!

DE is well documented for its ability to eliminate bedbugs. Even pest control companies sometimes use DE for removing bed bugs safely. Follow these steps if you see or fear bedbugs. For good measure, I sprinkle DE on mattresses each time I change the sheets to help ward off bed bugs and other pests.

4. As a Source of Silica

DE is 84-90% silica with over 20 trace minerals that are difficult to obtain in today’s world and needed by skin, teeth, and hair. A study from the University of Cincinnati’s College of Pharmacy showed that silica may help increase hair growth and thickness when taken regularly. The skin also uses silica and deficiency may lead to dry or brittle skin.

Studies show that dietary silicon is beneficial to bone and connective tissue, though the specific form in DE is not well studied. Evidence shows a positive association between dietary silicon intake and better bone mineral density, though the exact reason is unclear. One theory is that silicon helps the body synthesize collagen (which the body uses in joints, connective tissue, bones, and skin).

More research on the direct effects of DE on silica levels is needed, but silica itself is indisputably good for hair, skin, and nails.

5. To Assist in Detoxifiction

This is where claims start to get murky. On the one hand, there are thousands of products that claim to remove “toxins,” without clearly defining what “toxins” are. Since “toxins” is a term that could apply to a wide range of substances, these claims are difficult or impossible to measure.

On the other hand, there is evidence that diatomaceous earth may have a measurable affect on several substances that harm the body, including reducing aluminum and other heavy metals.

DE’s high silica concentration may also contribute to the detoxification claims. Some evidence suggests that silica may help fight free radical damage in a similar way to antioxidants. This may be due to its ability to remain stable and carry a negative electrical charge, attracting positively charged free radicals. Though largely unproven by actual research, this mechanism is likely the basis of the claims that it reduces oxidative damage and has anti-aging effects.

6. To Fight Parasites and Bacterial Overgrowth

When a family member was battling SIBO his practitioner had him drink DE daily to help bring his gut bacteria back into balance. There isn’t much research on DE’s ability to remove parasites in humans, but it is well documented in animal studies.

In one commonly cited study The Oxford Journal of Poultry Science examined DE’s role in reducing parasites and improving egg quality in organic and free-range chickens. The study essentially concluded that hens fed DE had better eggs and fewer parasites relative to controls.

If you happen to be a chicken struggling with a mite problem, DE is a great remedy. The method in humans is less clear, but many people have used DE internally to fight other types of intestinal parasites. Anecdotal reports abound of DE’s benefits in human parasites as well, but more research is needed.

7. As a Way to Reduce Cholesterol

Amazingly, the most well-researched benefit of DE for humans is not often mentioned. In fact, the only study I found that looked at DE as a dietary supplement dates from 1998 and examined its role in improving cholesterol levels. The results are fascinating:

  • Participants all had a history of high cholesterol
  • They took diatomaceous earth multiple times a day for 8 weeks
  • At the end of the study, the subjects total cholesterol had got down by 13.2%
  • LDL (“bad”) cholesterol decreased the most
  • HDL (“good”) cholesterol increased slightly

The researchers concluded that while the results were promising, further studies are needed with larger groups and a control group. Anecdotal reports abound of people who used DE to help with cholesterol levels. A family member saw a 30 point reduction in blood pressure numbers from using DE.

8. In Sensitive Skin Deodorant

I’ve been making my own natural deodorant for years now (using this recipe) and love it. Some people react to the baking soda in the recipe, likely because it is so alkaline and may irritate certain skin types. This recipe is a great sensitive skin alternative using diatomaceous earth in place of the baking soda.

9. To Fight Foot Fungus

DE is naturally drying and may reduce moisture. I couldn’t find any studies to back it up, but a friend claimed that sprinkling it in her socks daily helped her beat a decade-long battle with toenail fungus.

10. Mixed in Beauty Products

A bonus use for DE!

I personally love using diatomaceous earth on my skin in beauty products. My skin tends to be naturally oily, so I often add a little bit of DE to homemade facial cleansers and face masks to remove some excess oil. Bonus: It makes a nice natural exfoliant!

Cautions and Risks

It is VERY IMPORTANT to only use food-grade diatomaceous earth for consumption. Other forms of DE are not considered safe and can be harmful to the lungs if inhaled. Many of the misconceptions about diatomaceous earth comes from confusing these types. Food grade DE is recognized as safe by both the FDA and the EWG. Industrial grade has many uses but is not safe for human use or to inhale!

Avoid Inhaling INDUSTRIAL Diatomaceous Earth

Studies have shown that long term exposure to industrial DE can be dangerous. While it isn’t a good idea to inhale any form of powder, the same level of caution isn’t necessary with food grade DE, as this National Pesticide Information Center fact sheet explains.

Diatomaceous “Detox” Reactions

DE may cause die-off symptoms, so it is important to work up slowly. Some people don’t respond well to DE, and I always suggest working with a knowledgeable health professional for any kind of acute problem or when doing any kind of detox.

How to Take DE

At our house, adults take 1 tablespoon per day on an empty stomach (we worked up to this from a teaspoon over a period of weeks) and kids take a teaspoon per day (they started with 1/4 – 1/2 teaspoon).

Where to Buy Food Grade Diatomaceous Earth (& How It Tastes)

We use this brand since I was able to verify that it is food grade, though many local co-ops and feed stores carry food grade DE as well. It has a chalky/silky consistency and tastes like a very mild mixture of dirt and chalk, but we are able to just mix in water to take it daily. It can also be mixed into juice or coconut milk.

Disclaimer:

I am not a doctor and I don’t play one on the internet. Diatomaceous Earth has been recognized as safe by the Food and Drug Administration, but it is not intended to treat, prevent, cure or diagnose any disease, so use at your on risk.

    Hello!

    I really enjoy the health benefits of DE. I have been taking it off and on for about a year and experience better immunity, great skin and hair, and overall a good feeling in my gut. An older friend of mine even increased her bone density and minimized her arthritis!

    I have heard that it is dangerous to take it everyday for a long period of time, and many go on and off of it for weeks at a time. I really respect your opinion on this, so what do you reason on this?

    Appreciate it, thank you!

    I had a oily stain on my favorite shirt. It had been hanging in closet hoping for a cure. I thought anout it and sprinkle the DE dirt on it and let it set for 24 hours and the dirt removed the stain!

    I don’t know where you got all your information from, from sites that sell the stuff?
    These documented animals studies, where are these that you speak of?
    DE won’t eliminate internal parasites, definitely not when used solo. If it IS used internally, its housldn;t be used regularly, and in most cases will not kill fleas on your pet. Companies that sell it will tell you all this, its a marketing ploy.
    The only available studies are on Organic Layer Hens and Cattle both of which state that further research is needed and that it was either ineffective or slightly effective, neither of which are proof of efficacy across species.

    Have him (and you), eat and drink as many organics as you can. Read up on GMO’s and Organics. Try growing your own ORGANIC vegetables, and fruits! 95% of corn grown in the US is GMO (gentically modified organism), and “high fructose Corn syrup” is an ingredient in many foods and drinks (sodas and juice too). So your doing good to keep him away from corn. But, they feed GMO’s to all factory farmed animals, so your meat, and diary has GMO’s in them. Some organics, are expensive, but you can find deals, closeouts, sales, etc. Walmart, and Target stores, are putting them on their shelves, as more and more people learn about GMO’s! You can find a section of some grocery stores, with organics, but my Harris Teeter grocery store, has them all throughout the store. But sign up for newsletters, that will tell you the organic companies, that are lying, and selling out to Monsanto (I call them Monsatan). Education is the key to good health!

    Most everything you eat at the grocery store, has GMO’s (genetically modified organism) in them. And most crops are sprayed with many chemicals, pesticides, and herbicides, etc. Try eating and drinking as much ORGANICS as you can. (Clean food). There are many websites, that will keep you informed of GMO’s and Organics. Education is the key to good health!

    95% of corn crops in the US are GMO. Soy is too, but don’t know what percentage it is. “High fructose CORN syrup” is an ingredient they put in most all food products, and drinks (sodas, of course, and juices). They are now trying to change the name “high fructose corn syrup”, to something else, because people are learning about GMO’s (Genetically Modified Organism). Sounds yummy? Most people eat it, every day. There are websites, that will tell you about them, and what they will do to your body. Most all animal factory farms (from where you get your dairy and meat), feed them GMO grains.

    I’ll like to explain about regular diary and meat.
    All factory farmed animals, are given shots of antibiotics (because they live in filth), hormones (to make grow bigger, faster), and are fed GMO grain.
    95% of corn (other crops too), that are grown in the US, are GMO (genetically modified organisms). Look at ingredients in many products. You’ll find “high fructose CORN syrup” (Alos,in most every soda, and juice).
    A lot of grocery stores, have an organic section. My Harris Teeter, have their own organic brand, and many other organic brands, throughout their store. Look for sales, closeouts, etc. everywhere! Even Walmart, and Target stores, are jumping on the bandwagon, as people are learning about GMO’s.
    I stopped eating meats (organic grass fed, no antibiotic, no hormone meat is too high price, but will buy some, when I have the money). I started eating only organic, diary (ice cream, cream cheese, sour cream, MILK, butter, etc) Besides GMO’s, their spraying thousands of chemicals, pesticides, and herbicides, on all crops.
    Everyone wonders, what to do with their pain, diseases, their skin conditions, weight, etc. Look at what your putting IN your body! You ARE what you EAT! I lost 50 unwanted pounds (I was an 160pd female, at age 50), by switching to organics, and I will NEVER look back. I felt better, and really started looking SO much bettter (bad thing was, I had to buy a whole new wardrobe!)

    We have a flea problem at our house, with 3 dogs, that like to stay in the house, more than outside! I just bought some Food Grade DE (waiting for it in the mail), and I can’t wait to try it for my own body (thanks for the info, I will start slow on the amount). I’m not sure I want to use it on the carpets, so does it matter which one I use for the fleas on the carpets? I can use the regular DE for this, and not the Food Grade?

    Also, you mentioned above, in your article:

    “Diatomaceous earth (DE) is recognized as safe for human and animal use, and food grade DE is considered safe for human consumption…”
    The (regular) DE “safe for human and animal use” part….the word “use”, is not the same thing as “consumption”, that the food grade is?
    I’m just trying to figure out, what to use “regular” DE for, because you said you used DE for your son (GAPS diet), and for blood pressure, and didn’t mention it being Food Grade DE. (I guess I’ll go ahead and assume that it was, :))

    Yep, I started using it a couple of months ago in my morning smoothie. So far, so good…nothing really to report. I’m hoping to see changes in my hair!!

    I used it for fleas when my dog had puppies and I was unable to give her flea meds while pregnant and nursing. It worked extremely well for this purpose. Although I remember reading a warning on the food-grade DE bag NOT to inhale the dust. So even if you’re using the food grade product you still need to be careful about this.

    I’m curious about taking DE to close to thyroid meds. Any issues?

    Hi- wondering if anyone has had good results using DE against stink bugs? Thanks!

    So happy to see you talk about this great product. My husband and I have been using it for years. It’s part of how we normalized his cholesterol and it has helped me with detox and also keeping my bones and teeth healthy.

  15. Carrie Avatar

    I’m going to start taking DE to (perhaps) help with my hair & nails that age (I’m 64) and a long- standing thyroid condition have wreaked havock on…wish me luck!

  16. Trish Avatar

    Will it still have same positive effects if taken in a pill? I take tumeric and add it to empty vegetable capsules then swallow. Just easier for me. Curious if DE would be easy to put into capsules and absorbed properly in the body. If so, how much would you recommend starting with? Thanks for your time!

      I would say emphatically NO!
      DE needs to be in water first. It could be very dangerous and damaging to your digestive system if not used with great care and sparingly. There are too many people who have had serious medical reactions.

    Hi there. I was hoping to start using DE, but I was curious about when to drink it. Can I drink it after I take my thyroid meds? Or should I drink it first and then take them? Is there a tine frame I should wait?

  18. C Clark Avatar

    I am hesitant to try it again. When I first tried it I ended up with a terrible kidney infection that led to a kidney stone 2 years later. It could have been coincidental but I because I am not sure it scares me to try again.
