Problems solved by technology

However, the problem of moisture absorption in the preparation process of traditional Chinese medicine solid preparations has always been a common problem in the development of preparations. After moisture absorption, in addition to softening, agglomeration and even mildew, the fluidity of the drug will also decrease, thereby affecting the quality and efficacy of the drug.

Abstract

The invention discloses a preparation method of artemisia scutellaria and scutellaria baicalensis gallbladder-clearing granules, and relates to the technical field of traditional Chinese medicine preparation. The preparation method comprises the following steps of bagging talcum powder and indigo naturalis, decocting in bags, mixing with artemisia apiacea, bamboo shavings, rhizoma pinellinae praeparata, red poria cocos, scutellaria baicalensis, fructus aurantii, citrus chachiensis hortorum and liquorice, adding water for extraction, filtering, concentrating to obtain clear paste, centrifuging, adding auxiliary materials, drying and granulating to obtain the artemisia-scutellaria and scutellaria baicalensis gallbladder-clearing granules. The granules not only maintain the advantages of quick absorption and quick action of a decoction, but also overcome the defects that the decoction is inconvenient to decoct, large in dosage, easy to mildew and the like when being used temporarily.

Description

technical field [0001] The invention relates to the technical field of preparation of traditional Chinese medicines, in particular to a preparation method of Artemisinin Qingdan Granules. Background technique [0002] Haoqin Qingdan Decoction is the representative prescription of Yu Genchu ​​in "Rebooking Popular Treatise on Febrile Diseases" for the treatment of Shaoyang damp-heat and phlegm turbidity syndrome. It is now widely used clinically for a variety of exogenous febrile diseases, including many infectious diseases in modern medicine, infectious diseases and non-infectious febrile diseases, etc., and is also widely used in bile reflux gastritis, cholecystitis, biliary Calculus, urinary tract infection, typhoid fever, summer high fever dizziness, night sweats and other diseases. However, the oral dose of decoction is large, and it is inconvenient to store and carry. It takes time to decoct clinically, and it is not suitable for the clinical needs of some acute exogen...
