*Phosphorus (Phosphor.), Phosphorus, U.S.P.
Translucent, nearly colorless, waxy solid with a characteristic odor, becoming white, red or black on the surface on long keeping. Readily inflammable in air (preserved under water). Almost insoluble in water, to which phosphorus imparts its characteristic odor and taste; slightly soluble in dehydrated alcohol (1:400) and soluble in chloroform (1:17).
Action and Uses: In rickets for stimulation of bone formation. Its use as “nerve-food” is irrational.
Dosage: 0.5 mg. or 1/120 grain (U.S.P.). May be administered in pills or as phosphorated oil (1:100). The preparations are unreliable unless they have been recently made, since phosphorus rapidly loses its efficiency through oxidation.
