When the liquid temperature inside the stainless steel barrel reaches 95 DEG C, the raw propolis is melted in water and then the solution is stirred sufficiently until the particles are melted, so as to enable the raw propolis to be completely dissolved into water; then the stainless steel barrel is taken out from the big pot and cooled with the top cover closed; according to the steps of preparing raw propolis block, the raw propolis which is heated to dissolve in water is cooled, then the condensed propolis block is taken out and raw propolis block is taken out which is prepared into natural propolis after drying treatment. The method of preparing natural propolis without a non-alcoholic way has the advantages of retaining whole ingredients of propolis, improving yield and quality of propolis, reducing cost, non-pollution, being simple, convenient and practical.
