I am writing this in hopes that someone will read this and be helped like I am. I tried diatomaceous earth, using about 3 heaping tablespoons in a cup of water, to appease my husband. He said it would be good for my hair. It doesn't taste bad, it actually is good. However a week later we were driving to the store; I looked down and noticed I had nails. I have bitten my nails since I can remember. I went out and bought polish. I could not believe how fast they were growing and the urge to bite them was no longer there. My hair was also thinning in front and it is now filled in. When my 25-year old sister was pregnant, she craved chalk. Her husband would actually go to the store and buy her chalk to eat. I gave her some of the diatomaceous earth and she loved it. She quit eating chalk and took the diatomaceous earth every day."
There is a word for people who eat DE, clay, sea shells, etc.-- I never can remember it. . . when I read that someone eats DE, I have to caution them about their teeth. DE is SiO2 (silica), the mineral is QUARTZ. On Moh's Mineral Hardness Scale, Quartz is a 7 on a scale of 1-10 with 1 being the softest mineral (Talc) and 10 being the hardest (Diamond). Your teeth is CaPhO4 (calcium phosphate), the mineral is APATITE. On Moh's Hardness Scale, it is a 5 and Quartz (7) will severely/easily scratch Apatite (5). Your teeth are not going disappear overnight but surely, if you believe 2% Diatomaceous Earth put in feed and ingested is capable of shredding a parasitic worm which has evolved over the course of several million years to survive and thrive in the digestive tract of a bird then surely, it is not a great stretch of the imagination that the same stuff put in your mouth in a cup of water could interact with your teeth in some small, detrimental way.
In the 1960s in this country, a well known toothpaste company was putting minute amounts of the rock, "Pumice," a siliceous (also SiO2=silica=quartz) rock created when silica-rich magma is propelled through the air in a volcanic explosion, in their toothpaste. The pumice-laden toothpaste indeed cleaned teeth and made them pearly white. It also was quickly wearing the teeth, first the enamel and then the rest of the tooth. The company was immediately stopped and prevented from using pumice in their toothpaste.
About "chalk": chalk is made of microscopic, prehistoric shells called coccoliths. Coccoliths were an abundant animal (plankton) & especially flourished in the Cretaceous seas over 70 million years ago and their likes have not been seen so prolifically in any other time. Nobody knows why they were so abundant and then so suddenly, geologically speaking, instantaneously disappeared. There were also some deposits of them in the Upper Cambrian (485 million years ago) and later in the Miocene (25 million years ago) as well.
Coccoliths were so abundant a little more than 70 million years ago that their fossilized microscopic shells form large sedimentary layers in Upper Cretaceous aged rocks (e.g. the famous "White Cliffs of Dover" in the UK; the Demopolis Chalk here in Alabama; in Turkey near Sile along the Black Sea coast; quarries of Southern Sweden; the rolling plateau of Picardy in France; the Austin Chalk deposits in Texas; in Georgia of the former Soviet Union, in Israel & Egypt--- ALL Upper Cretaceous). To make these chalk deposits requires an extremely pure coccolith limestone-- almost entirely made of of these plankton shells! [Limestone is a rock chiefly composed of the mineral, Calcite] Coccoliths were plankton/animals with shells vs. Diatoms are plants, a small algae with shells. Coccoliths made their shells of Calcium Carbonate=Mineral is CALCITE/(Aragonite in new shells)=the oyster shell we feed our hens for calcium supplementation for stronger shells (the same mineral in other sea shells). I drink milk and eat cheese for my calcium. The DE has much less Calcium and Ca is just present as a trace mineral, if at all. It doesn't make sense that DE would fulfill a carving for the calcium that the chalk was providing. Do you hear what I am saying here?
