Embodiment 1

[0085] The raw materials were weighed according to the following weights: 500g of Rhizoma Chuanxiong, 800g of Epimedium, 300g of Ginkgo Leaf, and 450g of Angelica.

[0086] (1) Angelica and Rhizoma Chuanxiong were crushed into coarse powder, 7 times the amount (weight) of water was added, and the volatile oil was extracted by steam distillation for 4 hours until the volatile oil was exhausted. The aqueous solution after extracting the volatile oil was set aside. Add water to decoct the dregs twice, add 10 times the amount of water for the first time, add 8 times the amount of water for the second time, each time for 1 hour, combine the decoction, merge with the aqueous solution after extracting the volatile oil, and concentrate until the relative density is 1.06 (55°C), cool to room temperature, add ethanol to make the alcohol content 70%, let it stand, filter, and use the ethanol solution for later use.

Description

(1) Technical field [0001] The invention belongs to a medicine for treating vascular dementia and a preparation method thereof, in particular to a pure traditional Chinese medicine preparation for treating vascular dementia and a preparation method thereof. (2) Background technology [0002] Vascular dementia (VD) is an acquired cognitive impairment syndrome caused by different reasons and pathological cerebrovascular lesions. It is the most common type of senile dementia in my country, accounting for about 68.2% of the total number of senile dementias. At present, the number of people who die from senile dementia has become the fourth cause of death after heart disease, tumor and stroke. Therefore, the study of the disease is very important both in western countries and in our country. For the prevention and treatment of vascular dementia, Western medicine mainly uses drugs to improve brain metabolism and cerebral vasodilators, combined with rehabilitation therapy. Althoug...
