Many bentonite clays are acid leached, heated or tampered with in some way. If being used in or on the body, it is essential to use a food-grade clay because this will have been tested for heavy metals and other contaminants. Purely Earth’s clay is untreated and in its natural state.
Sodium bentonite tends to be less drying to the skin than calcium bentonite, and because it has a higher absorption ability it tends to be a better “sink” for toxins.
A quality clay should be milled to a 44-micron particle size and should have a low contaminant level. There are a number of clays on the market that contain a significant amount of feldspar, quartz or other mineral compounds and contaminants. Quality bentonite clay should be over 90% pure bentonite and should meet food-grade standards. Purely Earth Clay meets these specs.
Both food-grade calcium and sodium bentonite may be used internally. Sodium bentonite is the more active of the two clay types. Improved bowel frequency, better stool formation and decreased gas and odour are some of the benefits experienced by most people who use our clay internally.
Purely Earth’s Clay is one the best quality clays in the world. It meets the Australian Food Safety Standards and carries a Food Chemical Codex IV certification.
