Benefits and uses of bentonite clay
Wellness Mama » Blog » Health » Benefits of Bentonite Clay (& How to Use It)

In modern times we have largely forgotten that cultures throughout the ages used bentonite clay and other healing clays for their nutrients and to help rid the body of toxins.

If we take a cue from nature, many animals will instinctively turn to eating dirt and clay to help remove poisons from their systems or during times of illness or distress.

More recently, healing clays like bentonite clay have once again gained popularity for internal and external detoxification, and with good reason.

What Is Bentonite Clay?

Bentonite clay consists of aged volcanic ash also known as “Montmorillonite.” The name comes from the largest known deposit of bentonite clay located in Fort Benton, Montana.

It is an odorless grey/cream color with an almost soft, very fine consistency. Unlike some other clays, it doesn’t stain and is easy to work with in beauty and natural remedy recipes.

Healing clays like bentonite have a high concentration of minerals including silica, calcium, magnesium, sodium, iron, and potassium. It also absorbs and removes toxins, heavy metals, impurities, and chemicals.

Because of this, bentonite clay is a common ingredient in detox and cleansing products. Common external uses include poultices, mud packs, detox baths, and skin care recipes.

Some (including myself) even use it internally. It has an alkalizing effect on the body and when taken correctly, it can help balance gut bacteria.

Bentonite Clay Benefits & How It Works

Bentonite clay is a unique clay due to its ability to produce an “electrical charge” when hydrated. Upon contact with fluid its electrical components change, carrying a strong negative charge which bonds to the positive charge in many toxins.

When it comes in contact with a toxin, chemical, or heavy metal, the clay will absorb the toxin and release its minerals for the body to use. Bentonite also helps get oxygen to cells as it pulls excess hydrogen and allows the cells to replace it with oxygen instead.

Personally, I’ve seen people benefit from taking bentonite clay to help with:

  • digestive disturbances like acid reflux, constipation, bloating, gas, etc. (Kaolin clay was common ingredient in medicines like Maalox and Rolaids for years.)
  • helping with skin and allergy issues
  • providing minerals for the body
  • recovering from vomiting and diarrhea
  • detoxification
  • oral health preparations
  • externally for all types of skin problems and to speed healing

Even Dr. Weston A Price, in his book Nutrition and Physical Degeneration reported that several native cultures including those in the Andes, Central Africa, and Australia consumed clays in various ways. Commonly they would carry balls of the dried clay in their bags and dissolve a small amount of the clay in water with meals to prevent poisoning from any toxins present.

In a study from Arizona State University, bentonite clay was found to be highly effective at killing MRSA as well as Salmonella, E. Coli and others. What is promising as research continues in this area is that depending on the method in which the clay kills the infection, it may not be possible for the MRSA or other bacteria to develop a resistance to it as it does with antibiotics.

How to Use Bentonite Clay

Bentonite (and other clays) are staples in my homemade herbal cabinet and medicine chest. I’ve used them internally and externally for various issues on myself, my husband my kids. I order from here and it is an inexpensive natural remedy.

  • On the Skin: Externally, I apply a paste of bentonite clay and water on any skin irritation like blemishes, insect bites, cuts, skin itching, or burns. I leave it on until it dries and wash off. This is said to be especially calming to skin itching from eczema, psoriasis, chickenpox, etc.
  • Armpit Detox: I use a mix of bentonite clay and apple cider vinegar to detox my armpits. For more about why, see this post.
  • Skin Poultice for Bug Bites/Burns/Cuts/Stings: For more severe issues, I create a poultice by putting a thick layer of clay on the skin and applying a wet gauze or cloth over it. I wrap the area and leave the poultice on, changing every 2 hours. I’ve even applied this treatment on poison ivy.
  • Face Mask: Many beauty products use bentonite clay for its ability to bind with and remove toxins and impurities. For smooth and healthy skin, I make a bentonite clay mask simply by mixing a paste of bentonite and water. I leave on for 20 minutes and wash off with warm water. I typically do this once or twice a week. Bentonite clay powder mixed with apple cider vinegar also makes an excellent and balancing face mask.
  • Homemade Clay Soap: add clay to my homemade soapI to give it a silky feel. Bentonite clay soap is great for oily skin and acne
  • Detox Bath: I sometimes add about 1/4 cup of bentonite clay to bath water for a relaxing detox bath that softens skin.
  • For Oral Health: Because of its excellent ability to bind to heavy metals and toxins as well as to provide minerals, I use bentonite clay in my Remineralizing Tooth Powder Recipe. It can even be used alone for brushing and is tasteless and relatively textureless.
  • As an Oral Rinse to Whiten and Remineralize Teeth: Besides the use in my tooth powder, I use bentonite mixed with water as an alkalizing and toxin-removing mouth rinse. I mix 1/2 teaspoon of clay in 1/4 cup water in a small jar with a plastic lid and shake well. Then, I rinse with the water for 1-2 minutes and repeat until I’ve used it all.
  • For Mastitis: I’ve created a poultice or mask of bentonite clay and water and applied externally to the area. I repeat as needed every hour until the infection is gone. I also take internally during infection along with vitamin C and fish oil capsules.
  • For Baby Powder: Plain bentonite clay makes a very soothing baby powder for use when there is infection or redness. It can also be made into a clay “mask” to help speed recovery in this area.
  • For Digestive Problems or Morning Sickness: I took 1/2 tsp of bentonite clay in water during early pregnancy to ward off morning sickness. It helped with the nausea and helped me feel better. I checked with my doc/midwife first and was told this was fine. Check with your doctor or medical professional before using during pregnancy.
  • For Internal Cleansing: I drink 1/2 to 1 teaspoon most days in a cup of water. I combine in a glass jar with a plastic lid and shake until well incorporated. This has helped improve my digestion and also seems to give me more energy. Since adding this and getting gelatin in my diet I also notice that my nails and hair grow more quickly. Make sure that any clay taken internally is labeled safe for internal use. This is the one we use.
  • For Pets: For pets that are sick, vomiting or showing signs of illness, you can add bentonite to their water or mix and give orally with a dropper or syringe without the needle. I have seen several cases where this helped pets recover quickly from what could otherwise have been serious illnesses.
  • Other Uses: Though I have not needed to use for these reasons personally, I have read cases of bentonite and other healing clays being used internally to help reduce radiation exposure, in alternative cancer treatments, and in MRSA infections. It is also said to greatly help in parasite removal, though I have not tried this personally.

Best Bentonite Clay Brands (& Precautions)

  • Do not let healing clays like bentonite come in to contact with anything metal, as this will reduce the effectiveness. I mix with water in a glass jar with a plastic lid by shaking well or using a plastic whisk.
  • If you take it internally, do not take within an hour of food for best results and do not take within 2 hours of medications or supplements as it might reduce their effectiveness. Check with your doctor before using if you have any medical condition.
  • Because bentonite clays can contain lead (read my full thoughts on that here), it is important to get it from a reliable quality source. For example, a 2016 FDA study warned consumers not to buy a brand called “Best Bentonite Clay” out of Guthrie, Oklahoma, due to high lead levels.

Of course I always recommend that you do your own research, especially when it comes to controversial topics like lead exposure. Based on my findings, I feel perfectly comfortable using this brand externally and internally for our whole family.

We also use this clay-based toothpaste when we travel. The kids love the taste and I love that we’re keeping up on our oral health routine away from home!

    My 19month old son suffers from terrible eczema. We’ve done food elimination trials, natural skin products, EFAs, probiotics etc etc. Is it safe for him to ingest this? What dose would you use? Can I ingest it as I’m still breastfeeding him?

  2. Cassie Avatar

    The Aztec Secret one says that it is for external use only. Is this the one that you take internally?

    I want to start taking clay internally but I am not sure how to take it. I have read about mixing it with water and then letting it settle and then drinking the water but not the sediment on the bottom of the glass. Is that the best way? Or is it important to get all of the clay into you? Thanks!

    I’ve been using your remineralizing tooth powder recipe for a week now, just a week, and I see and feel a huge difference! I have wicked bad alergies, and dinky little teeth. I have a visible difference in the color of my smile. The half closest to the gums has always been darker. And I was told that I don’t have enough enamel to bleach them. I was told it’s just from sleeping with my mouth open, because of my allergies. But after a week, they’re almost uniform! Thanks for that!!! 🙂 I wonder what my dentist will say when I see him 🙂
    Next up, I have recurring nipple infections. So much so I’m about to stop nursing. But seeing that I can make a poultice, I brewed some chamomile tea, on the hot tea bag I threw a dash of tea tree oil, coconut oil, and topped it off with a good layer of clay. I’m going to sleep with it. Hopefully I’ll be cured overnight 😛

    Just out of curiosity, how would this work with mercury tooth fillings? My husband has one from years ago, unfortunately, and since this binds to metal, just curious to know if that would cause major issues?? Thoughts?

  6. Danielle Avatar

    Why does it say for external use only? Yet you use it in your toothpaste? I wanted to start using it but am wondering if its safe internally.

    Hey Wellness Mama! I love this article. I just wanted to point out that the bentonite you are linking to when referencing internal usage is not safe for internal use. I own it and use it as a face mask (and it’s awesome) but there’s a warning on the label not to ingest it.

    what is the difference between the internal and the external? I have some aztec clay…and it says for external only….and says it’s calcium bentonite green clay…I just wanted to try drinking it…but is there really a difference?

    I use this clay to brush my teeth with using my oral B electric toothbrush. Do you know if that’s not a good idea since there are metal parts INSIDE the toothbrush head?

    Diatomaceous earth food grade will take pin worms out of your system and can be sprinkled for othe bugs. Do not breath. Good for you because of high silica and calcium. Aggro green in ontario supplies. Do your research!

    I have the Aztec Secret Calcium Bentonite Clay and it says “NOT FOR EXTERNAL USE” on the back label. Do you ingest this clay? Or would you suggest drinking the bentonite from Mountain Rose Herbs?
    Thanks so much!

    I have been bleaching my hair (on scalp) recently since cutting it very short (3/8″ all over) and I also recently discovered I have Hashimoto’s disease, an autoimmune. I know the bleach is toxic but I was wondering if I were to use the bentonite clay baths and drink the mixture after bleaching my hair could I help release the toxic load from it? I have been so diligent in cleaning up my diet, lifestyle and all the other things that one does when discovering you have an autoimmune disease….changed my shampoos, lotions, soaps, laundry detergent etc. to homemade natural products but this new hair thing is something I absolutely love and I am hoping it is not just one more thing I will have to give up due to this thing called Hashimoto’s disease!

    Has anyone ever heard about using bentonite clay for plantars warts? Just wondering if I could use it for that and how. thanks!

    Do you or anyone take the Calcium Aztec Secrets brand internally? That is what I already have at home…

    1. Bein Avatar

      I have the Aztec Secret brand, and just called them to ask why there product says for external use only. She told me that it is just because they have not pursued FDA approval, so they cannot label it for internal use. But it is 100% Calcium Bentonite Clay, just like any other brand.

        I kinda figured this, reading the label, that is the only ingredient listed. I used this to make homemade toothpaste and didn’t have a problem with it. Followed the instructions on the label to make a face mask and it worked wonderfully

    I am trying to get copper out of my body – I’m pretty sure I have copper toxicity from an IUD (that’s now removed). I haven’t found very many ways to get the copper out – could the clay help? Any other suggestions or experiences??

    1. Lorraine Knight Avatar

      You need to take a zinc supplement and cut out high copper food like chocolate and avocado

    I just like to correct a grammatical error: “… its minerals for the body…” is the correct way, and there is no need for apostrophe like you have written “… it’s minerals for the body…”. Thanks for your attention.

    I mixed the bentonite clay with apple cider vinegar and have some extra left over from my mask tonight. Is it safe to store it in the fridge until my next use?

    Thanks for all the wonderful information! I just had my mom buy some and she was asking how exactly to take and use it. I did a quick search, found your site, and sent her a link. You made it really easy ; >)

      Yes. I was prescribed it by my doctor and am exclusively breastfeeding. I use Redmond Clay; it’s safe to ingest.
