Abstract

The medicine for treating ischemic cerebral disease is prepared with notopterygium, Chuanxiong rhizome, notoginseng, kudzu vine root extract, haw leaf extract, and gingko leaf extract in certain weight proportion. The preparation process includes supercritical CO2 extracting notopterygium and Chuanxiong rhizome pieces to obtain volatile oil; alcohol extracting notopterygium and Chuanxiong rhizome dregs and notoginseng and preparing the extract into dry extractum; merging the extracts and pressing into tablet. The medicine made of Chinese medicinal materials has high medicine purity, obvious curative effect, and can cure ischemic cerebral disease radically. The preparation process of the present invention has the advantages of high extraction rate, less medicine loss and simple operation.

Description

(1) Technical field [0001] The invention relates to a medicine for treating ischemic encephalopathy, in particular to a pure traditional Chinese medicine preparation for treating ischemic encephalopathy, and a preparation method of the medicine. (2) Background technology [0002] Ischemic cerebrovascular disease is characterized by high morbidity, mortality, morbidity and recurrence rate, which greatly endangers human health and is one of the three major causes of human death. Among them, ischemic cerebrovascular disease accounts for 56.6% to 80% of cerebrovascular diseases. At the same time, stroke is also one of the main causes of human disability. my country is a country with a high incidence and mortality of stroke in the world, with about 300 strokes per year. 10,000 people suffer from stroke, which is 1.5 times that of western countries. Chinese medicine has had a relatively systematic understanding of stroke since the period of "Internal Classics". After continuous imp...
