In medicine, chemical compounds from corals are used for cancer, AIDS, pain, and other uses. Coral skeletons, e.g. Isididae are also used for bone grafting in humans. Coral Calx, known as Praval Bhasma in Sanskrit, is widely used intraditional system of Indian medicine as a supplement in the treatment of a variety of bone metabolic disorders associated with calcium deficiency.
Coral calcium is a salt of calcium derived from fossilized coral reefs (primarily from limestone and coastal deposits). It has been promoted as an alternative treatment or cure for a number of health conditions.
Coral calcium is composed primarily of calcium carbonate (CaCO3), with small amounts of magnesium and other trace minerals. Calcium carbonate from coral is similar to calcium carbonate from other sources, with varying amounts of trace minerals. Much attention has been given to calcium carbonate’s ability to change the pH (or alkalinity) of water-based solutions to which it is added. With respect to pH and alkalinity, the calcium component is less important than the carbonate component, which is chemically similar to the bicarbonate in baking soda. Coral calcium is a source of calcium, which is an essential mineral for human life. Coral has a chemical structure that is very similar to the composition of human bone and is sometimes used as material in bone grafts.
