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!

    I used montollmonite (bentonite) clay to cure my valley fever. After being sick for over a month I drank a ton of it one day and was literally 95% better I still drink almost everyday good stuff!

    They line their trucks with rubber mats and use front end loaders that are lined with a rubber/plastic like coating. In any case it is prolong contact with metal you want to avoid.

    It is milled with grinding equipment. As soon as it is ground to a 325 mesh it is poured into 50 lb heavy paper bags with a safe plastic lining or one ton Super Sacks of woven heavy plastic, lined with a heavy safe plastic lining. You can mix clay in a blender, just wash the blades immediately afterward and do knot leave metal utensils in the clay for a prolong time.

    How is the bentonite clay mined? Do they use plastic spoons to dig it out of the ground because you say not to let it touch the metal spoon. Can you respond to this as it is a question that I have been asked before and am curious myself.

    Clay draws tightly when it dries pulling blood flow and oxygen to the surface where healing can begin. If you are fair skinned it is likely you will feel warmth and see redness for a short while. You might try not letting it dry completely. In some cases wiht rashes it can be a detox reaction.

    Hi Katie,
    I applied bentonite clay mixed with water on my face and on a few mosquito bites on my arms and legs. I left it dry for 20 min and my skin was red and sore in some areas when I rinsed. An hour later redness is gone. Have you or anyone you know experienced this? Any ideas of why Enid may have happened? Thanks!

    I’m not sure the question has been answered yet, but I’ve seen it posted many times and I am curious too as I have just order some Aztec Secret BC……is it safe to ingest despite the fact that it says “for external use only” on the jar?

      IF they state not for internal use there is a reason. The Living Clay Brand is a tested safe Calcium Bentonite Clay.

    i don’t use Aztec Secret. Brushing your teeth with it is not the same as swallowing it. It can be natural and no additives and not have been tested for purity. I don’t know why they label it that way other than they do not think it is safe to take internally. I personally use the Living Clay Brand. I find it is the most non-gritty clay on the market and is a triple swelling strong pulling effective clay.

    Thanks for all of the great info! I recently purchased some bentonite clay to make a toothpaste and am happy to learn more about all of the other ways I can use it. Although, I am wondering.. When I got home I read on the back that the clay said ‘For External Use Only.’ It happens to be the same brand (Aztec Secret Indian Healing Clay) that you use. Is this an issue when using in a toothpaste recipe or for other internal methods like you mentioned? It seems to be completely natural with no additives, so I am confused as to why they would say this on their product label.

    Soium Bentonite and Calcium Bentonite are like cousins yet different. They are named after the dominate mineral and the one that is exchanged or released into the body. Most sodiums are for industrial use and have been cleaned or processed some what which interfers with mother nature. Sodium Bentonites tend to be thick and gooey- plastic like not smooh and emulsified like the natural calcium Bentonites.

  10. Amy Avatar

    According to my information the sodium bentonite is NOT for internal use. The Calcium bentonite IS.

  11. Ulrika Avatar

    Hi, the clay that you have a link to, says it’s 100% Natural calcium bentonite clay.
    The clay I have at home, which I bought from Mountain Rose Herbs is made out of sodium bentonite clay.
    Do you know the difference? Does it matter which one I use if using your recipies?

    Help! I just did a bentonite clay and Epsom salt bath. I thought it was safe while nursing, but now my stomach hurts and I have a really bad sore throat. Should I pump and dump and give the baby frozen Stach from the freezer or am I over reacting?
    Thanks!!!

    We have a pure grey clay stratum in the creekbed on our farm. I’ve used the clay for skin problems with great success, I’ve had an infection above a tooth that has had a root canal; the dentist referred me to an expensive specialist. So I’ve been packing the tooth and gums with clay every night for 6 onths. No improvement, Any ideas?

    1. Brenna Avatar

      If you’ve had a root canal then the tooth is dead. That means it can harbor an infection factory that your blood and immune system have no access to. If the infection is already in your jawbone then you need that treated immediately after getting the tooth pulled.
      Having a dead thing in your body is not worth it. I had the same issue, root canals are scams.
      Been over 7 years since I had the root canal, finally had the tooth pulled 4 years ago after years of mystery illness and facial swelling leading to brain infections.
      I still haven’t totally gotten rid of the infection at the site where it was pulled. Bc part of my jawbone had very limited blood circulation due to the infection and I’ve been battling so many other health problems since that I haven’t been able to focus on it.
      The longer you wait to get the tooth pulled and treat it the less blood circulation you have to treat the infection after the tooth is pulled. My brother had part of his jawbone die bc he was determined to keep a root canalled tooth. Normal dentist can’t even test for these jawbone issues much less treat it and the rate of brain infections leading to tumors….
      Ok, so root canals are a scam. You cannot fix an infection connected to or fed by a dead part of the body.

        Thanks Brenna for your answer. I agree, and have been dreading the dentist visit. My dentist refered me to a endodontic dentist specializing in such. Or I can get it pulled, but it’s the last molar connected to another tooth via a bridge, so I lose 2 teeth without possiility of a bridge. Thinking about “what can go wrong” I am undecided. Don’t trust the endodontist, but I’ve had lots of root canals — prefer them to extraction. But you have stated my exact fears — so far health is fine, but….

        I have had many problems with teeth crowned without the root canal — after a few years they calcify — excruciating pain — and have to have a root canal. My Vietnamese dentist was an expert at root canals — no more trouble than a filling — for now. But I should be grateful that at 74 I am only missing 3 teeth.

          Are you taking raw fermented cod liver/butter oil? My teeth were all going bad due to malnutrition as a child. I discovered the raw fermented cod liver oil gets nutrition to my teeth and I’ve had no new issues since. I do also eat a diet according to the needs of my teeth. Meaning no Undigested “easy” carbs. I soak my beans. Ferment my bread (really just a natural fresh yeast starter I use instead of manufactured yeast crap.). Eat lots of healthy oils, especially olive.
          If your tooth is not dead you may have a chance to save it. I had a doc repair a tooth that had a giant hole in the side -decay down to the nerve. The tooth has no pain and doing great now. I did have two sidewalks totally intact though. Just some thoughts.

      For the person with a tooth ache that gets her clay from a creek bed. Are you packing the tooth with a quality dry powder clay. I would not use a creek bed clay this day in time for internal use.

          You might also apply the clay mask to the outside of the jaw and down under the jaw in the affected area. At night put a thin coat on and sleep with it all night.

    All Bentonite Clays are not safe for internal consumption. I would follow the manufacture’s advise and seek and edible. Some sources are Living Clay, Terramin Clay, Redmond Clay, or google for edible clays.

    Hi, I have Aztec Secret Indian Healing Clay and I’m interested in ingesting it for digestive help. I notice the directions say “For External Use Only.” Should we not ingest this clay if it clearly says it’s only for external use? Please explain. Thank you!

    You said this helps with reflux. My 16 month old has gurd and his naturopath wants me to give him half a teaspoon acv with each meal to replace the loss of his stomach acid. The acv is cause him to have bowel movements that burn his bottom. Would the clay be a good substitute? Does the clay help the body make more stomach acid?

    For years I’ve been suffering from severe itching under my arms any time I used a deodorant (only organic/no anti-antiperspirants). I tried just about every type of unscented/natural brand I could and nothing worked. It’s as if the oils clogged my pores so I couldn’t sweat properly. I also went to medical and dermatologist who had me try many scripts and nothing worked there either. Next, I tried washing with tea tree soap which helped with a rash under breast, but didn’t really help with underarm itch.

    So I had been reading about the benonite clay and decided to try. I bought the benonite clay because I thought maybe I needed to detox my underarms and lymph nodes. I used yesterday with organic apple cider vinegar. After rinsing my armpits were very itchy for hours into the evening, but this morning it has subsided. Something unusual but may not be related, my muscles around chest and underarms are semi-sore. I am unsure if I should continue using or look for an alternative. Any help or suggestions will be

    I use Dr. Schultze’s intestinal formulae which contains bentonite and charcoal among other things, and I feel it gives me the deepest cleaning I’ve tried so far.
