Abstract: The present invention provides a medicament of 1-calcium phosphate-uracil and method for preparing thereof. The method comprises mixing Na2HPO4.12H2O with H3PO4, adding uracil to said phosphoric acid working solution for dissolution, pouring obtained solution into reactor, adding creatine kinase, i.e. CPK, agitating, incubating, and standing at room temperature; filtering, pouring the filtrate into reactor, and disposing in a water tank; adding aqueous CaCl2 solution, agitating, incubating, and standing at room temperature; filtering the above material with clean silk cloth, discarding the filtrate, soaking in distilled water, drying. The medicament of 1-calcium phosphate-uracil has efficacy on auto-selected target. It can improve immunity and has a broad therapeutic spectrum. The medicament selectively works on target by self-catalysis and self-assemble effect of high energy phosphate, thus achieves broad-spectrum and safe therapeutic effect.
