Abstract: A method for preparing a micro capsules is described. Thus, 20-60% of matrix composed of methyl cellulose, ethylcellulose, HMC, HPC, polyvinyl alcohol, or polyvinyl acetate, etc. is sprayed into a saturated solution containing organic solvent, mixed with agitation at 30-60≦̸C for 12-24hrs, then blended with medicinal herbs extract, and freeze-dried or spray-dried to give microcapsule. To prepare a medicine for cold, a mixture containing the microcapsule described above (220 mg), 120 mg acetaminophene malate, and 3.75 mg aluminum stearic acid is filled in a soft capsule.
