Embodiment Construction

[0005] After harvesting the medicinal materials of Radix Pseudostellariae, clean it to remove impurities such as sediment and non-medicinal parts, wash it with tap water within 6 hours while it is fresh, and cut it into 3mm thick slices. Add this tablet to 5 times the weight of purified water at 70°C, stir for 30 minutes, filter, and squeeze the medicine residue to extract the juice. Then add 8 times the weight of purified water to the above-mentioned medicinal residue, boil for 20 minutes to extract, filter while hot, extract the medicinal residue again, and collect the medicinal juice. The above-mentioned medicinal juice was combined, concentrated under reduced pressure, and the temperature was set to 70°C, and concentrated to a clear ointment with a relative density of 1.20. After freezing the obtained clear paste at -80°C for 12 hours, it was vacuum freeze-dried at -40°C. The dried product is vacuum dried at 60°C to a moisture content of 8%, crushed, passed through a 60-me...
