Abstract

The invention belongs to the technical field of medicament, particularly relates to an application of liquiritin in preparing medicament for treating cardiovascular and cerebrovascular diseases, more specifically relates to an application of liquiritin in preparing medicine for treating cerebrovascular diseases. Pharmacological experiments reveal that liquiritin has distinct effects in resisting thrombosis, resisting cerebral ischemia, resisting cerebral anoxia and improving memory. The medicine with liquiritin as active ingredient has low medication dose and high safety, and has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of medicine, in particular to the application of liquiritin in the preparation of medicines for treating cardiovascular and cerebrovascular diseases, in particular to the application of liquiritin in the preparation of medicines for treating cerebrovascular diseases. Background technique [0002] With the improvement of living standards and the quickening pace of life, cardiovascular and cerebrovascular diseases have become the No. 1 killer threatening the health and longevity of middle-aged and elderly people. Among them, cerebrovascular disease is one of the three major causes of death in human beings. It causes severe physical disabilities, speech barriers, and more seriously, vascular dementia, which brings various changes to individuals, families and society. . Therefore, finding ways to prevent and treat cerebrovascular diseases has become a hot spot in current research. [0003] Licorice is the root...
