Silica is very common in nature and makes up 26% of the earth's crust by weight.Various forms of silica include sand, emerald, quartz, feldspar, mica, clay, asbestos,and glass. Silicon, a component of silica, does not exist naturally in its pureform. It usually reacts with oxygen and water to form silicon dioxide. Silicon dioxide has two naturallyoccurring forms: crystalline and amorphous. Most diatomaceous earth is madeof amorphous silicon dioxide. However, it can contain very low levels of crystallinesilicon dioxide. The first pesticide products containing silicon dioxide(diatomaceous earth) were registered in 1960 to kill insects and mites.
When diatomaceous earth is eaten, very little is absorbed into the body. The remaining portion is rapidly excreted.Small amounts of silica are normally present in all body tissues, and it is normal to find silicon dioxide in urine. In onestudy, people ate a few grams of diatomaceous earth. The amount of silicon dioxide in their urine was unchanged.
Most diatomaceous earth is made of amorphous silicon dioxide. However, it can contain very low levels of crystallinesilicon dioxide. Amorphous diatomaceous earth has not been associated with any cancers in people.
Diatomaceous earth is made of silicon dioxide. When chickens were fed a diet that contained less silicon dioxide thannormal, their bone formation was harmed. This suggests that silicon dioxide plays an important role in bone formation.
