First discovered in Aloe Vera by Rowe and Parks in the form of calcium oxalate, calcium is recognized as essential to the human system. Second in importance perhaps only to iron, it is especially required for the growth of young bone tissue. It is invariably interconnected with phosphorous, though little study has been made on the specific action of the latter.
Too much calcium in the system can create abnormal bone formation, deposits, and tissue hardening. Too little causes poor bone formation and stunted growth patterns, and would be comparable to setting the foundation of a building on papier mache. Its medical importance in the rebuilding of tissue is practically immeasureable. Ascorbic acid (Vitamin C) favors the utilization of calcium, as do the amino acids, Lysine and Oxalic acid, with which it works in frequent combination.
