[0035] The present invention also provides a preparation method of the above-mentioned Chinese medicine, wherein the dosage form of the Chinese medicine is granule, and the preparation method comprises the following steps:
[0036]The first step: mix the raw medicinal materials according to the stated ratio, add ethanol with an alcohol concentration of 70-80% 3-5 times that of the mixture, heat to boiling and reflux for 2-3 hours, filter, and use the reflux liquid as a solvent , using the filter residue as the solute, using the percolation method to slowly percolate at a rate of 1-2ml per minute, collect the percolation liquid, and then concentrate it under reduced pressure at a vacuum of 0.01-0.05Mpa to a relative density of 1.00 at 60-70°C ~1.05 paste, spray drying, the air inlet temperature of the spray dryer is 160-180°C, the air outlet temperature is 60-80°C, and then crushed into powder to make dry paste powder;
[0037] Step 2: Add 0.3-0.5 times of sucrose powder and 0....
