Abstract

The invention belongs to the technical field of medicine, and discloses a preparation method of a traditional Chinese medicine composition. According to the preparation method, ethyl acetate is takenas a solvent, heating reflux extraction is adopted so as to obtain a traditional Chinese medicine combination capable of clearing throats; high speed centrifugal process is adopted separation, purifying, drying, and dry method pelletizing are carried out, so that a solid preparation is prepared through a routine method. The preparation method is capable of shortening production period, increasingeffective component extraction rate, reducing dissolving out of ineffective components, achieving more accurate prescription curative effect, and improving medicine application safety.
