What is Bentonite? There are two main types of Bentonite clay. Sodium Bentonite Clay and Calcium Bentonite Clay. Lets look at each Calcium and Sodium Bentonites.
It contains a higher amount of sodium. It absorbs a high amount of water, and can expand up to 15 times its volume!
Sodium Bentonite has a high percentage of sodium in the crystal lattice.
Sodium Bentonite is mainly used in industries, as liner material, binders, suspension agents, cement tiles, concrete, wall boards and water-proofing building materials. They are also used in alternative health as an external detoxifier of skin and foot or as a poultice.
Sodium Bentonite absorbs and expands so much more than Calcium Bentonite, that if it is taken internally it could clump up with lack of water and cause constipation.
However it is extremely useful as a sealant in industries because of its very swelling nature.
Anyway the way it is mined for industrial purposes and the high amount of sodium present does not make it a good edible clay.
Some Sodium Bentonite clays are sold as edible clays. As a result of their high Sodium contents the Sodium clay has to be taken with Apple cider vinegar to neutralize the Sodium content. They must also be consumed in small amounts due to the high Sodium content.
But I would not recommend you eat sodium clay, as it absorbs too much water from your intestines, and could make you constipated. You wouldn't want that, right? I definitely do not. I
Sodium Bentonite is also mined for industrial purposes, so how hygeinically it is mined is another issue.
It can be used for external clay baths.
Calcium Bentonite, also called Calcium Montmorillonite. They contain more Calcium them Sodium. It is the rarest of Smectites.
Natural Calcium Bentonite that is a green clay, is well-known for its healing and curative powers because of its high adsorption and absorption powers. It can be used for external use. But, most importantly, this healing clay is extremely good when taken internally, for detoxing and removing toxins.
It is alkaline with a pH of 8 or 9 and above, and is tasteless and has no smell. It is also a smooth, non-gritty clay.
Calcium clays unlike Sodium clays, do not have any consumption restrictions.
Green Calcium Bentonite or Montmorillonite is the best clay for internal cleansing and detoxification. It is referred to as a Living Clay. I highly recommend a fine non-gritty and pure Calcium Bentonite for your internal cleansing.
