Example Embodiment
[0023] Example 1
[0024] Prescription ratio: 40 parts of Chuanxiong, 20 parts of Cnidium, 10 parts of Gentiana, 10 parts of hematoxylin, 10 parts of ebony, 10 parts of Magnolia officinalis, 10 parts of Schisandra, 10 parts of Chinese Gallnut.
[0025] The prepared 65% ethanol solution was injected into the extraction tank according to the volume of 10 times the mass of the medicinal material, and after sealing, the temperature was raised to 80°C, and the reflux extraction was performed 3 times, each for 1 hour. The refluxed extract was rapidly cooled to room temperature, centrifuged at 8000 rpm on-line high speed, and concentrated at low pressure at 50°C to the same amount as the original medicinal material. Use 1 times the amount of rice bran as an auxiliary material to absorb the concentrated liquid, mix it thoroughly in a mixing tank and then place it in a 70°C drying box for drying, and then crush it to obtain the product.
