preparation example Construction

[0022] The preparation method of the pharmaceutical composition of the present invention comprises the following steps:

[0023] A, take by weighing the Ginkgo biloba and Herba huixincao of formula quantity, pulverize and sieve, extract and obtain Ginkgo biloba and huixincao extract;

[0024] B, take the dragon's blood jelly and Gastrodia elata of formula quantity, pulverize and sieve for subsequent use;

[0025] C. Merge the Ginkgo biloba and Herba huixincao extracts extracted in step A with the dried dragon's blood and Gastrodia elata crushed and sieved in step B, mix evenly, and ultrafinely pulverize to obtain the target substance.

[0026] Pulverize and sieve in A step to cross 10 mesh sieves.

[0027] The extraction described in the A step is percolation extraction.

[0028] The extraction is to add an ethanol solution with a volume percentage concentration of 70-80% of the volume percentage of 8-10 times the solid-liquid volume ratio to the crushed and sieved ginkgo le...
