Bentonite Clay for Horses

The following is a guest post from Chris Richardson of The Holistic Horse:


Chances are you’ve heard of Bentonite clay and its amazing healing properties. If not, you are about to be introduced to one of the most incredible products provided by one of our favorite sources: “Mother Nature”.  Horse owners everywhere are discovering the phenomenal curative ability of this versatile purified “dirt”.

bentonite clay

Bentonite clay has been used by indigenous cultures since before recorded history. It is composed of weathered volcanic ash, and when used internally, it supports the intestinal system in the elimination of toxins. Bentonite clay is known for its highly absorptive qualities (think porous sponge or a piece of bread) and its ability to bind to and draw out heavy metals , chemicals, pesticides, bacteria, drugs and eliminate them from the body.

Bentonite clay also has electromagnetic qualities in that it has a negative charge which is naturally attracted to toxins in the body which have a positive charge. This negative charge is responsible for its amazing detoxifying properties both internally and externally. Bentonite clay can be mixed with water to make a paste or poultice for natural wound care and healing of hoof abscesses’. Therapeutic and essential oils such as lavender, peppermint ,clove, oregano, or tea tree can be blended into the poultice to further enhance healing.

In addition to being able to draw out toxins, Bentonite clay contains a wide range of nutrients and an abundance of minerals including calcium, magnesium, silica, sodium, copper, iron and potassium.

Many horses have experienced relief from pain, stomach ulcers, and chronic hoof abscess’s when bentonite clay is fed internally. Pure, food grade Bentonite clay provides many health benefits for people as well. For additional information about Bentonite clay visit this page.



Uses for People

In addition to equine use, bentonite clay is also great for people. Here are a few common uses and benefits:

  • Digestive disturbances like acid reflux, constipation, bloating, gas, etc. (clay was common ingredient in medicines like Maalox and Rolaids for years)
  • Helping with skin and allergy issues
  • To help provide minerals for the body
  • To help speed recovery from vomiting and diarrhea
  • Detoxification
  • In oral health preparations
  • Externally for all types of skin problems and to speed healing


Healing clays like Bentonite have a high concentration of minerals including silica, calcium, magnesium, sodium, iron, and potassium.

  • Skin Poultice for 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.
  • Face Mask: For smooth and healthy skin, I make a paste of bentoniteand water and apply to my face as a mask (a similar mask is used in many spas). I leave on for 20 minutes and wash off. I typically do this once or twice a week.
  • Detox Bath: I sometimes add about 1/4 cup of BentoniteClay to a bath for a relaxing detox bath that softens skin.
  • For Oral Health: Because of it’s excellent ability to bind to heavy metals and toxins as well as to provide minerals, I use BentoniteClay in my RemineralizingTooth Powder Recipe. It can even be used alone for brushing and is tasteless and relatively odorless.

  1. Question.. I am familiar with diatomaceous earth and use it as a daily wormer plus fly control on my horses but I have never used clay. Do you think it helps at all with sand removal from the gut? I live in a very sandy area and sand colic is something we deal with. I keep a lot of forage in front of my guys but psyllium
    ( Sand Clear etc) tends to make them gassy and their manure dry which worries me. Just curious as clay sounds very beneficial!

  2. Hi Terri,
    The clay is more beneficial as a detoxing agent. Ground flax seed is excellent for sand removal. Some people feed psyllium to their horses, ( the main ingredient in Sand Clear) but ground flax has so many more additional health benefits that psyllium does not. Flax seed is an excellent source of Omega Fatty Acids (EFA’s) which provide a wonderful soft and shiny coat. Flax seed also contains lots of beneficial fiber which provides an amazing intestinal cleanse. Flax also has natural anti inflammatory properties so it aids in helping with inflammation associated conditions such as arthritis. If you are interested we offer a great product called “SandGuard” (freshly ground organic flax seed for horses) available on our website. We also have ground flax for horses as a general nutritional supplement. The only difference in the two products is SandGuard comes with feeding directions for sand removal. Ground flax seed provides all the same amazing benefits for people as well! Enter “flax seed” in the search box on our website and all of our flax seed products will appear on one page.

      I feed supplements in “milled” flaxseed. Same benefits?

      • Casie says:

        Hi Mary, while flaxseed has some great benefits, it’s not exactly the same as bentonite clay. Personally, I might feed the clay short term for detox, but flaxseed long term since they’re a good source of omega 3’s and fiber.

  3. Tori says:

    Is there any additional information regarding hooves and abscesses?

    • Casie says:

      Hi Tori, you might check out the section on barefoot–pretty sure there are a few that discuss abscesses.

  4. Teresa says:

    What is the feeding ration for the clay and how do you feed it?

    • Casie says:

      Hi Teresa, I don’t remember the exact amounts, but if you contact Chris at The Holistic Horse (, she can tell you. Directions come with the order too.

    • HI Teresa, Full instructions come with the product and dose varies according to health ailment. For basic detox.. 2 Tablespoons mixed with a little water added to feed daily. For digestive or GI issues (diarrhea) dose can vary from 1/2 cup to 1 1/2 cups or as needed until condition improves.
