Bentonite clay has become a staple in our home from remineralizing toothpaste to armpit detoxes. I’ve even been known to rub it in my hair! There’s even evidence you can use bentonite clay for diarrhea.

 This home remedy is commonly used for detox protocols since it’s good at binding toxins and impurities. It’s also used for pimples, diaper rash, poison ivy, and other kinds of skin irritation – even gut irritation! It’s excellent at soaking up water in the digestive tract, which is why it’s sometimes used as a remedy for diarrhea. 

What is Bentonite Clay?

Bentonite clay is a substance derived from volcanic ash. It was first discovered in Montmorillon, France; hence its alternative name, “montmorillonite clay.” But today, the largest mining operation of this healing clay is in Wyoming.

There are two main types of bentonite clay: sodium bentonite and calcium bentonite. Sodium bentonite clay is extremely absorbent and is used for farming and industrial applications. Calcium bentonite clay is the type most often used for health benefits.

Bentonite is known for its ability to generate negative ions. The negative ions make it bind like a magnet to positively charged pesticides and other types of toxicity. It can also bind heavy metals like lead and cadmium. 

However, bentonite can do a lot more beyond detoxification. It also supplies key minerals, reduces inflammation, and supports the digestive system.

Is Bentonite Clay a Laxative?

Bentonite may help digestive issues like constipation-dominant irritable bowel syndrome (IBS). For that reason, people wonder whether bentonite clay is a laxative and if they should avoid it when dealing with diarrhea. The great thing about bentonite clay is that it can work either way.

Bentonite forms a gel-like substance when ingested. That added bulk may stimulate the movement of waste through the intestines. However, experts warn that taking too much bentonite powder or not drinking enough water may worsen constipation. 

You could also say that adding more powder and limiting fluids could help with diarrhea. As it creates that gel-like substance, bentonite also soaks up water in the digestive tract. It may help both humans and pets with diarrhea.

Why Does Bentonite Clay Help With Diarrhea?

Bentonite can help with diarrhea for both humans and pets like dogs, cats, and horses. In fact, it was shown to effectively treat 97% of all-cause diarrhea back in the 1960s. If you’re thinking of using it for pets, just be sure to check with your vet first. Here are the ways bentonite may work for diarrhea:

Absorbs Water

Bentonite clay absorbs water in the digestive tract, which is one of the main characteristics of diarrhea. As excess water is absorbed in the gut, it’s easier to form more solid stools. 

Adsorbs Toxins from Infections

Bentonite clay is an effective binder of all sorts of pathogens. It’s well-known that infections like bacteria, viruses, and aflatoxins trigger the immune response. Sometimes, that can lead to diarrhea. 

Traveler’s diarrhea, for example, comes from consuming food or water contaminated with bacteria or parasites. Infections often cause the body to do an immediate purging to rid itself of the invader. If the pathogen is eliminated, the body no longer needs to purge. 

Alleviates Allergic Reactions

Sometimes diarrhea is the result of an allergic reaction. When someone has a food allergy or intolerance, their immune system reacts to specific proteins in the food, triggering symptoms that may include diarrhea. Common food allergens that may trigger diarrhea include cow’s milk, soy, wheat, eggs, shellfish, and tree nuts. Bentonite may help lower the inflammatory response and slow the diarrhea.

If someone has a severe food allergy (like a peanut allergy) it’s best to seek medical attention if they’re accidentally exposed. 

Instructions: How to Use Bentonite Clay for Diarrhea

Here’s how to use bentonite clay to address diarrhea symptoms:

1. Mix 1 teaspoon of bentonite clay powder with 8 ounces of water.
2.  Use a non-metal container and spoon to avoid interactions with the clay’s properties.
3.  Stir well until the clay is fully dispersed in water.
4. Drink the clay mixture slowly – it may have a mildly earthy taste. Start with 1 dose a day and pay attention to your symptoms.

 If the diarrhea persists, then consider increasing it to two doses daily. Just remember that adding too much can create the opposite problem, leading to constipation. 

The FDA has approved bentonite clay for internal use and has given it GRAS status. Just be sure you’re using food-grade bentonite clay free of additives. Taking excessive quantities has led to extremely low potassium levels. However, it has a low risk of side effects when used in moderation.

Does Bentonite Clay Heal the Gut?

Bentonite clay is excellent at detoxifying the gut and promoting healing. Its strong adsorptive properties mean it helps to eliminate toxins and heavy metals in the gut. Removing these irritants can help reduce inflammation, setting the stage for healing.

In animal studies, the combination of bentonite clay and zinc oxide reduced intestinal permeability. In other words, it helped to heal a “leaky gut.” It was specifically shown to improve intestinal mucosal integrity.

In some studies, bentonite clay has reduced the growth of harmful bacteria and pathogens in the gut, like E. coli. It’s also been shown to increase gut bacteria that produce short-chain fatty acids (SCFAs) like butyrate, which reduces inflammation. 

Bentonite may also simply increase the activity of our natural gut flora. Having a healthy microbiome is crucial for nutrient absorption and overall wellness. It’s particularly important for maintaining a robust immune system.

Bentonite may help reduce symptoms like bloating, gas, and diarrhea by absorbing excess fluids. It’s a traditional remedy for diarrhea and to soothe the stomach lining (including ulcers).

How Do You Use Bentonite Clay on Your Stomach? 

You can use bentonite clay externally on the stomach, too. A poultice or compress can help with digestive discomfort, bloating, and minor dermatitis. 

1. Add 2-3 tablespoons of bentonite powder to a small (non-metal) bowl.
2. Slowly add water, mixing continuously until it forms a thick paste. It should be spreadable but not too runny. 
3. Apply a thin, even layer of the clay paste directly onto your stomach. You can cover the entire stomach area or focus on a specific spot where you feel discomfort.
4. Allow the clay to sit on your stomach for 20-30 minutes. As it dries, you may feel a tightening sensation. You can lie down and relax during this time for the best results. 
5. Gently rinse off the clay with warm water once the time is up. Pat your skin dry with a clean towel.

You can use this method 1-2 times a day as needed for relief. However, avoid overuse as it may dry out the skin.

Bottom Line

Bentonite clay is one of my favorite pantry staples for skin care and overall natural healthcare. I love having it around to make fun things like clay masks and DIY toothpaste. But it’s also there for diarrhea, acne breakouts, skin infections, and poison oak when needed.

You can get pharmaceutical-grade bentonite clay here that’s safe for both internal and external use.
