Embodiment 1
[0012] Example 1: Take the blood of Feilongzhang and dry the medicinal materials, pulverize them to obtain the coarse powder of the medicinal materials (the requirements of the coarse powder meet the requirements of the "Chinese Pharmacopoeia"), soak the coarse powder of the medicinal materials with 10 times of water as a solvent for 30 minutes, and decoct 3 times, each time for 1.5 hours Combine three extracts, concentrate at 65°C, -1.0mpa under reduced pressure; filter the concentrate; take the filtrate and centrifuge at low speed for 10 minutes, then centrifuge at high speed for 10 minutes. Take the supernatant obtained after centrifugation, and concentrate under reduced pressure at -0.6mpa until its relative density is not less than 1.04. Oral solution can be obtained by filling and sealing after damp heat and high pressure sterilization; if it is made into powder for external use, it needs to be concentrated to a relative density of 1.15-1.3, dried under normal pressure or...
Embodiment 2
[0013] Example 2: take the blood of the dragon's palm and dry the medicinal materials, pulverize them to obtain the coarse powder of the medicinal materials (the requirements of the coarse powder meet the requirements of the "Chinese Pharmacopoeia"), soak the coarse powder of the medicinal materials with 10 times of water as a solvent for 30 minutes, and decoct 3 times for 1.5 hours each time Combine three extracts, concentrate at 70°C, -0.8mpa under reduced pressure; filter the concentrate; take the filtrate and centrifuge at low speed for 15 minutes, and then centrifuge at high speed for 15 minutes. Take the supernatant obtained after centrifugation, and concentrate under reduced pressure at -0.8mpa until its relative density is not less than 1.04. Oral solution can be obtained by filling and sealing after damp heat and high pressure sterilization; if it is made into powder for external use, it needs to be concentrated to a relative density of 1.15-1.3, dried under normal pre...

Take the supernatant obtained after centrifugation, and concentrate under reduced pressure at -1.0mpa until its relative density is not less than 1.04. Oral solution can be obtained by filling and sealing after damp heat and high pressure sterilization; if it is made into powder for external use, it needs ...
