Abstract

The invention relates to an improved preparation method of a ligusticum wallichii tea-regulating pharmaceutical composition. The preparation method comprises the following steps of: mixing an extracting solution obtained by carrying out reflux extraction on the raw medicinal materials including ligusticum wallichii, notopterygium root, asarum, divaricate saposhnikovia root, mint and schizonepeta with an extracting solution obtained by decocting the raw medicinal materials including radix angelicae and liquorice, carrying out vacuum concentration to obtain thick paste, and then adding a matrixin a certain proportion to prepare the ligusticum wallichii tea-regulating pharmaceutical composition. The preparation method is simple and convenient in production process, good in stability and highin safety, and the product quality is convenient to control.

Description

technical field [0001] The invention relates to the field of medicine preparation, in particular to an improved preparation method of Chuanxiong tea medicinal composition. Background technique [0002] Chuanxiong Chatiao Dripping Pills, a product of Guizhou Jianxing Pharmaceutical Co., Ltd., are effective in dispelling wind and relieving pain.
