Abstract

The invention relates to a composition capable of treating vascular dementia, which is prepared from the following raw materials in parts by weight: 10-20 parts of ginseng, 10-20 parts of ginkgo biloba, 10-20 parts of huperzia serrata, 5-15 parts of szechuan lovage rhizome, 5-15 parts of earthworm and 5-15 parts of polygala root. The composition has simplified composing prescriptions and accurate curative effect on curing vascular dementia. The invention further relates to a preparation method of the composition, which comprises the following steps: taking ginseng, grinding, and extracting ginsenoside; taking ginkgo biloba, and extracting the total flavone of ginkgo biloba; taking szechuan lovage rhizome, and extracting essential oil; and decocting the residual medicinal materials, merging decocted liquid, filtering, concentrating to condensed paste, adding the ginsenoside, the total flavone of ginkgo biloba and the essential oil of szechuan lovage rhizome, adding auxiliary materials, and preparing a pharmaceutically acceptable preparation. The method is adopted to prepare the composition so that the composition can be ensured to be used conveniently and have controllable quality.

Description

technical field [0001] The invention relates to a pharmaceutical composition and a preparation method thereof, in particular to a composition composed of traditional Chinese medicines and a preparation method thereof. Background technique [0002] Vascular dementia (Vascular Dementia, VD) refers to the acquired intelligence impairment syndrome caused by cerebral dysfunction caused by ischemic cerebrovascular disease. Aspects of mental decline or disappearance as the main performance. It is equivalent to diseases such as "forgetfulness", "good forgetfulness", "dementia", "literary idiocy" and "epilepsy" in traditional Chinese medicine. [0003] The onset age of VD is related to cerebrovascular disease, generally after 50-60 years old, and it is more common in men clinically. The production of VD has a close causal relationship with cerebral ischemia. Hypertension, heart disease, hyperlipidemia, diabetes, drinking and smoking are risk factors for its onset. Asymptomatic str...
