Embodiment 1

[0061] Preparation of Rhizoma Chuanxiong Extract

[0062] method 1

[0063] Chuanxiong sliced ​​and soaked in ethanol for 8-48 hours, slice thickness 1-5mm. The powdery crude extract of Chuanxiong was obtained by ethanol extraction. The crude extract of Rhizoma Chuanxiong was subjected to CO2 supercritical extraction to obtain total alkaloids of Rhizoma Chuanxiong in brown oily form. The extraction temperature was 55°C±5°C, the pressure was 5-8Mpa, and the time was 0.5-1 hour.

[0064] Method 2

[0065] Take the rhizome powder of Rhizoma Chuanxiong, add ethanol to reflux to extract, combine the extracts, concentrate under reduced pressure to 1 times the volume of the medicinal materials, refrigerate, filter, add ether to the filtrate, extract the ether phase with sulfuric acid, adjust the pH of the water layer to 9-10, and extract with chloroform , the chloroform layer recovered the solvent, added sulfuric acid to dissolve, filtered, added an equal amount of chloroform to t...

Embodiment 2

[0074] Preparation of Capsule Compositions

[0075] Take Chuanxiong extract and Qingfengteng extract with a weight ratio of 2.5 to 1, pulverize, pass through a 100-mesh sieve, add appropriate amount of dextrin and starch, mix well, make soft material, granulate, dry, and pack into capsules.

Embodiment 3

[0077] Preparation of Granular Compositions

[0078] Take Chuanxiong extract and Qingfengteng extract with a weight ratio of 2 to 1, pulverize, pass through a 100-mesh sieve, add appropriate amount of dextrin and sucrose, mix well, make soft material, granulate, dry, and pack.
