They is research where they grow these things in the lab. But basically, the human physiology is more complicated, and the formation depends on what is in solution to keep them in solution as much as the actual elements. Plus there are several types of stones.<quoted text>
You mean that kidney stones are caused by an accumulation of calcium oxalate in the organ.
Kidney stones usually comprised of a compound called calcium oxalate, are the result of an accumulation of dissolved minerals on the inner lining of the kidneys. These deposits can grow to the size of a golf ball while maintaining a sharp, crystalline structure.
So, obviously, it means an excess of Ca^2+ ions that bond with oxalate anions C204^2- or (COO)2*2- form kidney stones.
Stay away from Rhubarb and spinach - they have 100x more oxalate than other foods.
K stones suck. I have had several of them, and each time I ended up in the ER.
