Calcarea Carbonica

Calcarea carbonica, commonly known as calcium carbonate, is a chemical compound with the formula CaCO₃. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcium carbonate) and is the main component of pearls and the shells of marine organisms, snails, and eggs. In Hebrew, it is called חלמון (khalmon), and in German, it is known as Kalziumkarbonat. In the context of homeopathy, Calcarea carbonica is derived from oyster shells and is used to treat a variety of ailments, including digestive issues, anxiety, and fatigue. It is also used in agriculture to neutralize acidic soil and as a dietary supplement to provide calcium. The compound is widely used in industry as a building material, abrasive, and filler, among other applications.
