Our Calcium Bentonite Clay is harvested from naturally occurring volcanic ash in the United States. It is perfect for incorporating into face masks and toothpaste, and is safe for internal use.

This pharmaceutical-grade clay, which is often used both internally and externally, is carefully harvested from naturally occurring volcanic ash in the United States. It contains high levels of trace minerals including silicon, magnesium, calcium and potassium. It is gaining popularity for its ability to help draw toxins out of the body and speed the healing process.

Used in and for:

  • Oral health, including mouth rinses and toothpaste
  • Internal cleansing (by itself, or in mixes like Detox+)
  • Detox baths
  • Skin infections and irritations (such as acne, warts, eczema, etc.)
  • Baby powder
  • Internal cleansing for pets
  • And much more! Scroll down for recipes and testimonies from our customers to find out more of what Bentonite Clay is great for.

How It Works:
Bentonite Clay is a very unique substance, formed primarily of Montmorillonite, which is an extremely flat crystal flake, that carries a relatively strong negative ionic charge. The negative charge is compensated for by adsorbing a cation (in this case, Calcium) to the interior of the molecule. This is what makes it either Sodium Bentonite or Calcium Bentonite. To put it another way, think of the Montmorillonite crystal flake resembling two pieces of bread, with a strong vacuum pulling the filling in between them. Whatever lands there (Sodium or Calcium) determines what kind of sandwich it will be. Now when you activate this clay sandwich, it will magnetically grab the junk in your body (heavy metals, toxins, acid, etc.) and trade it for the "filling”, taking the toxins out in your waste. The two different clays although very similar in their inert state (dry), have very different applications when activated (mixed with water). Our Calcium Bentonite clay is only slightly swelling or non-swelling, and this allows the clay (if it is as finely sifted as ours) to pass uninhibited through the colon wall, where it will go on to clean the blood while giving vital minerals to the bones.

Bentonite Clay and wildlife:
Peruvian Macaws seem to somehow know the benefits of Bentonite clay. Macaws are entirely dependent upon wild fruit for their main source of food, but at certain times of the year only poisonous fruit is available. So they will fly to the nearest clay lick and eat the clay in the morning which will adsorb the alkaloid toxins found in the poisonous fruit they eat during the day. Its highest power lies in the ability to absorb toxins, impurities, heavy metals and other internal contaminants. Bentonite clay's structure assists it in attracting and soaking up poisons on its exterior wall and then slowly drawing them into the interior center of the clay where they are held in a sort of repository.

Why our Bentonite Clay?
Not all Bentonite Clay is created equal. Most of it is not mined for internal use or sifted as finely as it should be. Here at Bulk Herb Store, we’ve carefully selected a Calcium Bentonite that is unsurpassed in purity and quality. Harvested from its natural source in the United States, it is triple cleaned and purified to maintain the highest standard for pharmaceutical and food-grade quality.

Bentonite Clay and your pH Balance
Another factor that makes Bentonite Clay Powder so indispensable is its ability to elevate your body’s pH. The Bentonite will absorb some of the hydrogen from your cells, enabling them to fill that space with the oxygen you so dearly need.

Instructions For Taking Bentonite Clay Internally
If you are using the bentonite clay internally for a cleanse we recommend the following dosage amounts: Start with a ½ - 1 tsp. of bentonite clay in a glass of water or juice, once a day for several days. When you feel ready to increase the amount, you can work your way up to taking 1 to 2 Tbsp. a day. When raising the amount, be sure to do it slowly, allowing a few days between each increase. The Bentonite clay needs to be taken on an empty stomach, so when you do take it make sure it is at least 2 hours before or after a meal. The best time to take the clay is early in the morning or mid-day. We do not recommend taking it before bed. Be sure to drink at least eight 8 oz. glasses of water! This is a must to ensure an effective cleanse as well as to keep you from getting constipated while taking the clay. If you are not having bowel movements every day, then drink more water or add extra fiber to your diet.


Bentonite Clay Toothpaste
We decided to make an all natural toothpaste recipe that would neutralize acid, remove bacteria-filled organic matter, leach out infection and promote healthy gums. Check out our Bentonite Clay Toothpaste recipe!

Bentonite Clay Mask
Similar to masks used at the spa, a clay mask made from Bentonite draws excess oils and debris to the surface of your skin, boosts circulation to tighten the skin and stimulate blood flow, and whisks away dead skin cells that can clog pores. Mix Bentonite Clay with water to make a paste, apply to the face, and allow to dry for 20 minutes. Wash off gently and pat dry.

Bentonite Clay for skin irritation
To control itching: A simple “mud pack” made with bentonite clay powder and enough water to create a thick goo can help control the itch and dry up blisters, herbalists say. Spread the clay over the affected area and let air dry. Keep it on until the clay wears off or gets itchy. Wash off the residue.

First Aid
To make a healing pack, mix Bentonite clay powder or baking soda and oatmeal with water and an anti-infection herb (such as garlic, thyme, or calendula) or an herbal tincture. Apply to pimples, boils, or wounds.

From Our Reading and/or Experience...

  • Do not use metal utensils or containers to stir or store Bentonite clay powder. Contact with metal may decrease the clay's potency.
  • The internal use of Bentonite clay is an excellent and simple way to do an effective cleanse. Among other benefits, it can reduce body odor, skin blemishes, and digestive track issues of all sorts.
  • The clay can be stirred into water, juice or any other beverage of your choice. It can also be sprinkled on foods or encapsulated.
  • We keep it on hand, among other items, to use internally and externally in case of snake bites or any other kind of poisoning.
  • Bentonite clay can be used to benefit anyone: men, women (including before, during or after pregnancy, and nursing), children, and animals.

  • Bentonite Clay Toothpaste Recipe

    Try our Bentonite Clay Toothpaste, made with all natural ingredients that you can make at home!



    1. Mix the first four ingredients in a medium saucepan, and simmer 30 minutes. While that’s heating, mix 1 tablespoon baking soda and 1 teaspoon Celtic Sea Salt and set aside.
    2. Next, place 1 cup of Bentonite Clay into a glass bowl. Note: it is important to use a glass bowl and wooden spoon because when the Bentonite Clay gets wet, it sets up an electromagnetic reaction which will absorb the particles inside of a metal bowl, or the toxins out of a plastic one.
    3. Remove saucepan from heat and strain off herbs, catching the liquid in a glass bowl. Slowly add the salt and baking soda mixture. Expect it to foam and bubble. This is the cinnamon and the baking soda reacting to each other. While it is still frothing, pour the liquid mixture into the bowl of Bentonite Clay, and whisk briskly. The foam will start to settle down and a smooth paste should start to form.
    4. Continue to add the remaining Bentonite Clay until the desired consistency is reached. Store in glass jars and avoid any contact with absorbable metals.
    5. That’s it! You’ve just made your own natural toothpaste!
