Featured: Did You Know...?

  "What is the evolutionary significance of plant toxins and animal anti-toxin behaviour? From a plant's evolutionary perspective, a seed should be high in nutrients to support germination and seedling growth; the ripe fruit around the seed should also be nutrient-rich and attractive to animals, encouraging them to pluck and eat the fruit and disperse the seed. On the other hand, the seed itself should be repulsive to animal consumers, inducing them to regurgitate or defaecate it, and the unripe fruit should be repulsive, lest animals harvest it before the seed is viable. From an animal's evolutionary perspective, an ability to defeat the plant's toxin defences would enable it to obtain the nutrients in the seed as well as those in the ripe fruit, and to outcompete other animal consumers by harvesting the fruit while it is unripe and still unpalatable to them.

"Any textbook of animal biology describes the resulting evolutionary arms race, in which plants evolve increasingly potent toxins (such as strychnine and quinine), and animals evolve increasingly potent means of detoxification. While enzymatic detoxification has previously received the most attention, the work of Gilardi et al.10 and the wide distribution of geophagy among animal herbivores suggest an additional important means of detoxification by adsorption on ingested soil minerals."

- Jared M. Diamond, Department of Physiology, University of California Medical School, Los Angeles

Eytons' Earth is not a clay sales company. We have no products for sale at this time.

We receive many inquiries concerning the purchase of healing clays. It can be difficult to find a supplier and gauge the quality and suitability of the various clays that are available for purchase on the market. This page is intended to serve as a general guide to buying clays suitable for use with the human body-- it is, however, by no means definitive!

When Buying Healing Clay, What to Avoid and Why


Please take a moment to view our special section on clay chemistry which clarifies the meaning of terms such as bentonite and montmorillonite!

There are many companies both on the Internet and off who specialize in retailing so-called healing clay.  We have anonymously contacted many of them, and we have field tested many products.  We believe that there is a great social responsibility when a person or group of people endeavors to market an untested ( or simply unaccepted ) alternative treatment in any type of medicine.  In our opinion, harsh though it may be, most of these marketing companies fail absolutely, both in understanding the product they sell, and in representing it with integrity.

Do not purchase clay products that are sold in unsealed containers, as there is a strong chance that the clay will have become contaminated during shipping and storage.

Avoid clay products with additives of any kind, unless one is certain about the compatibility of the additives and clay for human use.

Where to Buy Healing Clay

V.E. Irons Inc.

If one still wishes to purchase hydrated bentonite in a form ready for use internally, we recommend products by V.E. Irons, Inc.  V.E. Irons, Inc. has been in business for decades, and has contributed to the knowledge base of humanity with their own research staff.  V. Earl Irons, founder, was a pioneer in natural products long before most of our country knew what a supplement was.  They have published papers and been involved in the vitamin/supplement movement since its inception.  They have various patented methods for creating their final products. Their internal clay, one of the first bentonites to reach market in ready to consume form, is USP Grade rather than FDA grade, which is the exact road we would take if marketing a similar product.  Notice that they sell their product in a GLASS UV PROTECTED container.  While clay does not need to be protected from sunlight, this is standard packaging procedure for their hydrated products. Our hats are off to to the fine family who has contributed so much to the world of mineral supplements.

American Colloid Company

The American Colloid Company sells various forms of bentonite for industrial and pharmaceutical use.  They market a standard unprocessed 325 mesh technical grade bentonite that works better than Aztec or any other so-called healing clay ( pure bentonite ) that I have tested on the open market.  They do NOT recommend its use for healing and we have tested it for external use only; indeed, they really have no idea that bentonite can be used as a healing agent.  No large quarry or processing plant can recommend its clay for use on the human body and be in compliance with the FDA/USDA guidelines that regulate their industry.  However, unlike Aztec and some others, when you purchase this clay, you are guaranteed that it is free of grade related contaminants ( 325 mesh bentonite is tested for bacterial contamination and other potentially harmful contaminants ).  They do not directly sell to the public; one must find a supplier.  They sell it in powdered form for a fraction of the cost one would see online or in a health food store.  For internal use, they sell a pharmacy grade bentonite which the FDA has approved for use in the human body.  While more expensive than the 325 mesh industrial grade clay, its price ( once the powder is hydrated ) is still a fraction of the cost you'd find from a specialty carrier.

We've also tested American Colloid HPM-20 Agricultural grade clay for use in baths, and it performs admirably.


Pascalite is a rare specialty clay ( Calcium Bentonite ).  Although not nearly as affordable as a standard bentonite, we believe the price is justified because they truly offer a fine specialty clay.  Ray P., founder of Pascalite, is reputably quite a character.  His book is also available directly from Pascalite. Their products may be ordered by using the following URL:


Engineered Ceramics - EMX

Dr. Teruo Higa of Okinawa developed this unique product line based on a philosophy of Effective Microorganism engineering ( EM ). While we have never used EMX, we understand the principles by which Dr. Higa has formulated his products. Ceramics and clays have an incredible dense molecular structure, and if Dr. Higa has indeed succeeded in engineering a ceramic product which exemplifies clay properties, then his product is certainly worthy of serious consideration. His products for use with the human body are designed to effect the electromagnetic fields generated both by the body and by artificial devices. It should be noted that where "solid-state" products are concerned, about 10-20% of the general population can feel immediate effects, about 50% cannot perceive a difference, and about 30% may feel a general improvement in well being.

All of his products are reasonably priced, excepting his refreshment drink which costs an amazing $70.00 for 500 cc's! His products may be viewed at the following web site address:


A Word About FDA and Other Purified Clays

An example of a 50 lb bag of 325 mesh bentonite - notice the warning that clay dust from powdered clay should not be inhaled."FDA grade" clay may or may not maintain the healing potency of natural and USP grade clay. These clays tend to be over processed, bleached, and sometimes chemically washed and irradiated.

When we submitted two samples of clay for lab analysis, one FDA grade and one natural, the group doing the analytical work elected not to even study the FDA grade clay after preliminary work using Transmission Electron Microscopy. The processed clay was described as useless mud! To qualify this statement, FDA grade clay ( and other "purified" clays ) will still maintain their ability to adsorb substances, and thus may still be sufficient for internal cleansing programs. Needless to say, our recommendation is to use a natural or USP grade clay for internal use.

Finding Clays for Use in Natural Medicine

Local ceramic supply stores often carry at least one brand of pure bentonite.  They traditionally carry a few variations of bentonite for use as an additive to clays used for ceramics/sculpting that contain additives in them, so be certain that you get a pure bentonite.  If necessary, ask to view the Material Data Sheet that the store will have on file for the clay.

Most ceramic supply stores are small enough to offer old fashioned personalized customer service.  The person in charge of ordering their clays may have access to suppliers that carry American Colloid Company clay, and perhaps clays from Pfizer and other manufacturers as well.  I highly recommend purchasing clay in the 50 lb. bags that the manufacturers ship them in.

Construction firms often have access to bentonite suppliers as well, as do drilling companies.

Finding Natural Clays

An embankment of healing clay fragments covering a pure veinThe more adventurous soul may wish to find a natural source of clay for use. There are very important considerations to remember whenever finding a natural source of green clay that one wishes to use on or in the human body. The following is NOT all inclusive, but may serve as a general guide on natural clay sources.

A local miners' association or mineral society may have information about natural deposits in local regions. In the U.S., the Bureau of Land Management may have maps available that show natural clay deposits.

Usually, one finds a natural source for green clay because a subterranean vein has reached the surface. Surface clay in regions that have a high level of rainfall will most likely have succumbed to excessive leeching. When one finds a green clay on the surface, however, at least one vein will be nearby. It is worth the search to find this "pure vein", because the pure form of the clay should be used for testing purposes. Remember that hundreds of thousands of years have gone into the development of natural clays, and anything could have been sorpted into the clay during this time. Clays that have been subject to human-made waste products or clays that are located near any industry should not be used in the human body.

It should be noted that nearly, if not all, natural green clay sources located in the United States were known and used by indigenous cultures before the modernization of America. It can be well worth the time to research the area thoroughly to see if any clay found was used by Native Americans. This is not as easy of a proposition as it may first appear. Most of the modern tribes have long since lost the art of clay healing. Those who have kept this tradition alive will most likely not speak of it at all to "outsiders".

In our case, it took a year to determine that the natural clay had in fact been in use for over 10,000 years. There were two tribes indigenous to the area that had no knowledge of clay use in healing.

Obviously, if one is able to determine an extensive history of human use, and the environment has not gone through drastic changes, then the found clay will undoubtedly be both safe and effective for use. There is a comfort, in fact, knowing that a product has been successfully used for hundreds if not thousands of years! Our own modern medicine has much less of a proven history, and is in fact not doing very well against infections as nature responds to antibiotic use!

Having found and acquired a natural clay, the only certain method to determine safety of use is via laboratory analysis. If certainty is essential, then one would be best advised to take the clay in the purest form available, hydrate it with distilled water until it forms a consistent gel, and have a lab perform the equivalent of USP testing. It should be tested for anti-microbial properties, heavy metals, mineral content ( ionic content as well as dissolved solids ), and the PH balance should be determined. Salt / Sulfur contamination is a common occurrence through leeching. While these types of clays may have very special properties for external use, it is not offhand recommended that these be used for internal use.

There is considerable expense involved in such testing. Students of natural medicine, armed with considerable knowledge about health, may wish to perform some more affordable tests to determine the properties and the potency of any given natural clay. Again, always start with the purest form of clay available. Ideally, the clay is taken directly from the vein, where it is in solid form. If the clay from the pure vein crumbles easily, there is a good chance it contains various salts.

Often, clay taken from underground will be moist. Allow the clay to dry in a clean environment. Measure out ( estimate if needed ) about one cup of clay. Place the clay in a glass container. Slowly hydrate the clay by adding very small amounts of water. Keep a running total of the amount of water used. Keep in mind that it does take time for clay to incorporate the added water. Keep adding water and determine if the clay is expanding into gel form. A high potency green clay will adsorb 3-5 times its volume in water. Clay contaminated with excess impurities will not do so.

Provided that one has been successful producing a clay gel, the next step is to begin once more adding water. In this case, the amount of water added does not need to be measured. Slowly add water, again in a see through glass container. When adding water, the clay should begin to disassociate, and one should notice only water and clay. At this point, do not add "too much" water to create a liquid,rather just enough water to observe what is actually occurring as a result. Mix the solution. As more water is added, many impurities, if present, will begin to separate from the clay, either rising to the surface or dropping toward the bottom of the container. There will usually be sediment that DOES drop to the bottom, and this is normal.

If no impurities are noticed, then take some clay gel and set it aside to dry. Upon drying, salts and sulfur will leave a white residue. If this residue is excessive, then the clay has sorpted large amounts of these substances which may not be noticeable without the drying process.

If the clay appears relatively pure, and has exhibited the "swelling" that is characteristic of green clays, then take some "magma" or "gel" and cover about 1 square inch of the back of the hand with the clay used about 1/2 inch thick. Do not compress the clay, but make certain there is uniform skin contact. Do not allow the clay to dry. Keep it on the skin for a few minutes, then gently remove it and clean the back of the hand with a body-temperature wet wash cloth.

Observe the skin for signs of a chemical reaction or irritation. Any such reaction may indicate a high presence of compounds that may make the clay unsuitable for use. However, there ARE a few specialty clays that DO react upon the skin that have great value for use. The operative idea is that if one is not sure - get sure! A pure green clay, while it will quickly remove impurities from the skin, will not cause a chemical reaction with the skin itself. There ARE many thermal reactions that can occur when using bentonites and other healing clays; the back of the hand is the chosen testing point to minimize the chance of mistaking a different type of reaction from a chemical one.

These are a few ideas that give one a general indication of the purity of a natural green clay source. If the history of a clay source is unknown, and one cannot submit samples for lab testing, then one should carefully begin testing the clay.

If the swelling properties of a clay are not present, then one may have found a different type of bentonite. Keep in mind that this document expounds on the properties of a pure bentonite, not a bentonite compound nor any other type of clay that may be suitable for use.

The color of natural bentonite will vary from a dull gray, to a green gray, to a deep and rich green.

Subject: Bentonite Clay from Australia


I am trying to find a bentonite product in Australia, and its quiet hard to find a trustworthy seller.

Does food grade mean that it is purified, and could not have the healing potency?
If that product is not good, which one would you recommend me in Australia?

Thank you!

Subject: Re: Bentonite Clay from Australia

Hi Deniz:

Based on the information on their site, I wouldn't trust the things that they state.

For example, they state that there clay has no aluminum in it, and then state that there clay is an aluminum-silicate. The statements are misleading, as aluminum is an element of the periodic table, and it does't "dissapear" just because it is bound with silica. Either they are purposefully being misleadking, or they are simply confused.

They don't share how their clay is processed, and I can't find the AU/NZ standards that they mention.

If you want a raw healing clay that has only been milled (to a 325 mesh), look up Echolife, AU.

Subject: shipping clay by plane - radiation

Does shipping healing clay by plane affect it? Since packages are scanned before being lowded, I suppose the clay absorbs radiation and is therefore not good for healing use any more?

Subject: i reckon a few people wouldnt mind knowing the answer to this one

This seems to be the most honest and genuine source of info on healing clay....so i thought i might ask a question. I have some kind of fungal infection on the foreskin of my phallic member....with occasional "balantine" symptoms of a red ring like soreness......wouldnt mind getting rid of it but its been hanging around for a good while now..........im a bit bewildered by the amount of clays available and to be honest not really sure which one i ought to get hold of to do an overnight wrap, and this is after over an hour surfing the web on a clay mission. Is there any chance you could shed some light onto my plight....i wouldnt ask normally and would just try find out for myself but i'm definitley getting a bit confused. BTW in case anyone is interested...MMS in a spray bottle didnt work and i actually suffered mild burns as a result. Ive had good results with MMS for other stuff but it just didnt work for this one.

thanks for a great website ...well appreciated

Since this is a 'comment section', I will try to be brief.

Some clays are mildly antifungal, and some clays have no effect on fungus itself (in hydrated form). The benefit of using a good quality healing clay is the ability of clay to pull infections out the body; the clay does not necessarily need to kill the microorganism.

My favorite infection clay is the green desert clay outlined in our Tecopia Essentia section. We still use Terramin in a few of our detox formulas, but for external use, we use other clays.

Since the MMS didn't work when applied topically, there is obviously a barrier that the MMS couldn't pass. This could be due to the way fungii colonize, or the root of the infection may be deeper in the body.

Either way, I would mix clay with eleictrically isolated silver (ionic silver, especially for topical applications). Use clay overnight, and also before showering.

Hi Shamil:

Surface clays can be contaminated with potentially dangerous bacteria. Usually, sea clays are not, due to the high salt content from the sea water. It would be best if you verify it is a tidal clay (subjected to regular bathing in sea water).
