PURPOSE: An amorphous turmeric extract and amorphous curcumin are provided through cooling below a melting point after heating a turmeric extract or curcumin to reach above the melting point. CONSTITUTION: An organic solvent extract of turmeric is obtained in a pure solution state by extracting turmeric with a solvent and filtering. The turmeric extract is heated at a range of 180-240 deg. C for 0.1-10 minutes, and amorphous curcumin is obtained by cooling with a temperature below 190 deg. C. A solubilization component of the turmeric extract includes an amorphous turmeric extract solution in which the amorphous turmeric extract is dissolved in a biocompatible solvent selected from one or more of a group composed of linear alcohol or branched alcohol with 1-4 carbons, poly ethylene glycol with 100-1,000 number average molecular weight, glycerol, acetic acid, and polyoxyethylene sorbitan fatty acid ester.
