[0036] Prescription composition:
[0037] Pseudostellaria 2000 parts by weight
[0038] Pueraria 500 parts by weight
[0039] Epimedium 100 parts by weight
[0040] Preparation Process:
[0041] Take Radix Pseudostellariae, add 12 times the amount of water (equivalent to the weight of the crude drug), soak and extract once at 95°C for 2 hours each time, filter the extract with gauze, combine the filtrates, and concentrate under reduced pressure to a relative density of about 1.19 . Add ethanol to a final concentration of 80%, let it stand overnight, and remove the supernatant. Add water to dissolve the precipitate to a density of 1.060, then add ethanol to a final concentration of 70%, let stand until no more precipitate precipitates, and remove the supernatant. Freeze-dry the precipitate to obtain the total polysaccharide;
