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!

    Hi, love your site! Is there a reason why you use sodium bentonite over calcium bentonite internally? I initially read that the calcium would be safer because it doesn’t swell as much, and less likely to cause internal distress. I plan on using both…sodium bentonite for the bath, and calcium bentonite internally, but I’m curious about your perspective.

      I would be comfortable using either one, I just order everything from MRH so it is easier to order all together 🙂

      1. Donna Avatar

        Something to consider. If the calcium bentonite actually contains calcium in it (and I assume it does), the calcium will bind with all metals, and remove them from the body. There are a lot of people on this thread concerned about the possibility of aluminum poisoning and/or exposure with the bentonite clays internally. If you are not sure, and you really want to try this clay internally, I would gamble with the calcium one (which is said to be for internal use), as the most acceptable risk (if any) to take. Calcium is a natural chelating agent, and binds with metals to remove them from the body. I suppose, you could also take calcium and apple pectin along with the sodium bentonite as a precaution if you want to take both, or just in case. Both calcium and apple pectin bind with, and help the body excrete heavy metals.

    I am amazed with bentonite clay. I bought some originally to make my own toothpaste and as I was researching it more I came across this site. My son is 6 months old and has had a couple of eczema patches on his head. They were raised, red, and very dry and he has had them for about 4 months. I tried all sorts of stuff including cutting out common food allergens and using coconut oil and hydrocortisone. I put some bentonite clay on them and after only 20 mins it was almost completely healed! I used it the next day and can barely see what used to be there. This is something I will always keep on hand.

    Will i be able to use it to get rid off candida? and if so how will i be able to use it and for how long. Also will i have to change my diet in order for it to work very well?

    shouldn’t you differenciate between calcium & sodium kinds of bentonite clay? I heard calcium is internal & sodium is external & it’s recommended to take psyllium husks for constipation & not with food or medications

        My daughter currently has a yeast rash and I just bought that aztec secret bentonite clay because a friend recommended it. Do you think it is better to use as a paste or just sprinkle it on? I got a prescription ointment from the doctor but it isn’t helping much and I would prefer using something natural anyway. I had also planned to use coconut oil on her. Should I just mix the clay with the coconut oil? Would love to know your thoughts!

  5. jamie Avatar

    I put some clay on my hands for my eczema. I have done this twice now and each time they have gotten much worse. Is this normal for the rash to get worse before it gets better or have I maybe had a reaction to the clay?

      It can if it is pulling toxins, but I’d maybe try in another area to see if you react…

    I am having the hardest time doing anything with this clay besides making a mess. I can’t get a paste that isn’t clumpy. I tried making a mask but it wouldn’t smooth out well at all and I tried a bath as well and it also wouldn’t smooth enough to add anything other than spots on my tub. It sounds so benefitial but I’m kind of hating it right now. Any tips? Thanks!

    1. Wellness Mama Avatar
      Wellness Mama

      For mask- get hand wet and dip it into the clay and rub on the face. Repeat until you get enough to cover your face in a mask. For the tub I always dissolve it in a little bit of water first and then add to the tub…

        Thank you! I have also been having a hard time with using this as a facial mask. It just ends up turning into big clumps, no matter how much I mix it and add water. Is there any other liquid that I can use instead of water for a facial mask?

        1. Ceara Avatar

          Apple Cider Vinegar – that’s what I use to smooth it out – makes a huge difference!

        2. Jane Avatar

          It mixes smoothly with raw Apple cider vinegar. I shake vigorously in a glass jar with a plastic lid. Open right away because it swells. Much better than water. One part clay to two parts vinegar.

        3. Kathy Avatar

          I read that you can powder your face with the bentonite clay and then spray your face with water.

    2. Jessica Avatar
      Jessica

      Mix the calcium bentonite clay with organic apple cider vinegar and keep adding till it’s the consistency you want. That should do the trick for the face mask (:

  7. Deanna Avatar

    Has anyone used it on kids after vaccines? And for what ages is it appropriate to use? Just wondering if it would help eliminate any of the aluminum or any bad reactions

    Noticed that you referred us to Mountain Rose Herbs to buy the clay, but on their website in the description of the clay, it says “For External Use Only.” I have emailed the company to ask why. I’ve been using calcium bentonite clay for a couple things and was interested in buying in bulk as we’re using it more and more. Their website also shows that what they stock is sodium bentonite clay. Anyone have any reliable resources regarding the difference between the two?

    Two questions…
    1. is this safe to take internally while nursing?
    2. Does this interfere with good beneficial bacterial and flora in the gut? If not, how does it distinguish between good and bad bacteria?
    Thanks!

    1. Dena Barnes Avatar
      Dena Barnes

      i’m also curious about the nursing issue. I’d love to see a source that talks about if the body ends up detoxing any of this out via milk or not.

      Did you ever find out the answer to your Bentonite to Good Flora question? That is something I am also curious about. Donna Schwenk said she thinks its fine but that didn’t make me think she knew for sure….TIA

    I love Bentonite clay….it is so good for any skin ailment – bug bites, pimples, even poison oak. I wouldn’t want to be without it.

    Thank you for posting this. I use bentonite clay on my face for blemishes and other skin irritations. My boyfriend buys empty capsules from the health store and will fill them with clay to be taken internally to cleanse the digestive system.

    I’ve tried the liquid bentonite clay, but not the powder one, I did a cleanse but didnt see much effect from it, could it be because it was liquid? I have a stomach virus called H Pilori and that sucker is hard to get rid off! The doctor has given me antibiotics and other medicines but it only calms it for bit but after a while it comes back.. Could this work to remove this virus as well?

    1. Candice Avatar

      The Mayo clinic suggests this (and it closely matches the published study from U of Cal done perhaps 20 years ago that showed Bismuth and Tetracycline to cure H. Pylori and ulcers.)

      Bismuth Subsalicylate, Metronidazole, and Tetracycline (Oral Route)

    2. Michael Phillips Avatar

      The best cure for H Pilori is fresh ginger! It’s natural abilities kill off the virus, and help balance the flora in the intestinal tract. It has worked wonders for us!

      The antiviral and antibiotic medications deplete the good “critters” in your digestive tract, and with time unbalance the system to the point of chronic constipation and or diarrhea. Ginger only kills off the excess and bad flora. It takes a few days, and you will fart and belch, but that’s only showing its working!

      I make some fresh ginger candies, and keep it in the freezer. At the first sign of indigestion, suck on a pice or two, and it almost always calms and releases the pressure and discomfort.

        Hi, could you please share your recipe for making the candy? I would really like to try this for my chronic nausea, thank you.

    Hi there! I was wondering if you have a trick to avoid the clay clumping? I shook it in water, but still has little clumps 😀

          Is it ok to use the whisk ball mixer cups if the whisk is metal???

    2. james Avatar

      I mix mine in a bottle of water, if you close the lid and shake it up it mixes much better. if you let it sit for a little bit and shake it up again most of the clumps should break up. some will settle on the bottom again if you let it sit and dont drink it all at once, but just shake it again before you drink.

    3. Audrey Avatar

      I add about ten medium size stones give it a good shake in my covered Tupperware and have no clumps of clay. I discovered this by trial and error:)

  14. debbie Avatar

    Hi,

    Quick question, you mention taking the clay internally but on the mountain rose website that you link to it says that the bentonite clay is only for external use. Is it OK for internal use?

    1. Wellness Mama Avatar
      Wellness Mama

      I’ve taken it internally for a long time. When I talked to them, they explained that due to laws in some places where different products are sourced, they can only list some things as for external use…

    1. Caleb Avatar

      Consult a doctor but why would pulling toxins out of your body hurt your baby? When i take it internally my armpits start stinking big time!! One time i took too much and had to drink more water. I am now just taking a tablespoon ,2, or 3 in some water every morning. Also take a tablespoon of chia seeds EVERY morning it creates a muconoid coating on your intestine wall that makes disposal of even the worst foods a breeze. The magnetic electric pull of this stuff is incredible. I like to do a full body wrap at the beach and then go swimming in the magnesium salts (ocean). Then put coconut oil on skin because it can leave the skin a little dry.

    mountain rose herbs says the clay is for external use only, is that the same clay you take internally?

    1. Wellness Mama Avatar
      Wellness Mama

      Yes, from my understanding, their certification just allows them to sell it for cosmetic use on certain products, though it is the same product one could get elsewhere for taking internally.

      1. julie Avatar

        From what I’ve read, Sodium Bentonite Clay is only good for external use, and Calcium Bentonite Clay is safe for internal use.
        I emailed the kind folks at Mountain Rose and they informed me their BC is Sodium Bentonite.
