[0023] Table 1 is the composition embodiment of the present invention
[0024]
[0025] The preparation method of Examples 1-5, (1) All the Chinese medicinal materials weighed in the above examples except borneol and ethanol are heated and refluxed for 6-7 hours according to the mass ratio of 1:15-20, and the solid-liquid separation is carried out under vacuum. Recover the ethanol solution to make the extract into a thick paste; (2) mix the thick paste extract and water at a ratio of 1:3-5, add the borneol in step (1) and stir to mix evenly to form a mixture. The temperature of the recovered ethanol solution is 55-65°C, the vacuum degree is below 780mmHg, and the density of the thick paste extract is 1.05-1.13 g / cm 3 .
[0026] Immerse the filter element completely in the mixed liquid, and when it stops absorbing the mixed liquid, take out the filter element and bake it at a temperature of 55-65°C and a vacuum of 780mmHg or less for 1-1.5 hours.
