Preparation method of traditional Chinese medicine granules capable of relieving exterior syndrome, dispelling coldness and dispersing dampness

Abstract

The invention discloses a method for preparing a particle preparation of a traditional Chinese medicine for relieving exterior syndromes, dispelling coldness and dispersing dampness. The method takes notopterygium root, ledebouriella root, atractylodes rhizome, asarum herb, rhizome of Sichuan lovage, dahurian angelica root, baikal skullcap root, liquorice and rehmannia root as raw materials; the dahurian angelica root is crushed and then percolated by ethanol; the notopterygium root, ledebouriella root, atractylodes rhizome, asarum herb, rhizome of Sichuan lovage, which contain volatile components, are crushed, soaked and extracted to obtain naphtha, the medicine residues and the baikal skullcap root, liquorice and rehmannia root are mixed, added with water and subjected to extraction, concentration and alcohol deposition, and the obtained alcohol solution is mixed with the percolate of the dahurian angelica root and concentrated to be extracturm; and the obtained naphtha and the extracturm are added with proper amount of auxiliary materials for medical purpose and prepared into a particle preparation. The medicinal materials for extracting the naphtha are subjected to crushing and soaking treatment, thereby greatly improving the yield of the naphtha, improving the leaching rate of volatile active components and enhancing the curative effects of the medicine.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, in particular to a preparation method of granules for relieving the exterior, dispelling cold and dehumidifying.

AI Technical Summary

Problems solved by technology

[0003] Directly add notopterygium, fangfeng, atractylodes, asarum, and chuanxiong to the five medicinal materials of water distillation, and the distillation process parameters are not strictly formulated, resulting in low yield and poor quality of volatile oil, which directly affects the quality of the product and the efficacy of the drug; while the existing process is in production It is not easy to control in the process, it is not conducive to large-scale production, and it is unstable during the storage period, resulting in unclear identification; the loss of volatile components also affects the curative effect of the drug
