Abstract

The invention relates to a method for preparing tablets for treating pharyngitis. The method comprises the following steps of: performing microwave extraction on tree peony bark, and purifying by using a macroporous absorption resin to obtain tree peony bark extract; performing microwave extraction on indigowoad root, and Chinese white olive, and purifying by using the macroporous absorption resin to obtain indigowoad root and Chinese white olive extract; performing CO2 supercritical extraction on figwort root, the tuber of stemona (processed), asparagus fern, dwarf lilyturf tuber, common coltsfoot flower (processed), oroxylum indicum, rehmannia glutinosa, and periostracum cicada to obtain supercritical extract; and mixing the tree peony bark extract, the indigowoad root and Chinese whiteolive extract and the supercritical extract, adding dextrin, pelletizing by using 70 percent ethanol, drying, spraying peppermint oil, tabletting, and wrapping film coatings. The tablets for treatingpharyngitis, which are prepared by the method, are convenient to take.

Description

technical field [0001] The invention relates to a preparation method of medicine, in particular to a preparation method of traditional Chinese medicine. Background technique [0002] Pharyngitis Tablets are made from Scrophulariaceae, Baibu (made), Asparagus, Moutan Bark, Ophiopogon japonicus, Coltsfoot Flower (made), Wood Butterfly, Rehmannia glutinosa, Radix Isatidis, Green Fruit, Cicada Slough, and Peppermint Oil as raw materials. The second volume of "Ministry of Health's Drug Standards for Traditional Chinese Medicine Prescriptions" nourishes yin and nourishes the lungs, clears heat and detoxifies, clears the throat, relieves cough and itching. It is used for dry throat, itchy throat and irritating cough caused by chronic pharyngitis. [0003] In the prior art, there is no report on the choleretic effect of Pharyngitis Tablets. [0004] In the prior art, the preparation of Pharyngitis Tablets adopts the method of decocting in water. The process is rough and backward,...
