Embodiment 1
[0052] Embodiment 1 prepares Acanthopanax oral liquid
[0053] Wujiaqi Oral Liquid: The prescription includes 800g of Astragalus and 200g of Acanthopanax.
[0054] Preparation method: crush the above two traditional Chinese medicines into the coarsest powder, add 8 times the amount of water, soak for 1 hour, decoct and reflux for extraction for 2 hours, filter, add water to the filter residue and extract twice, add 8 times the amount of water each time and reflux for 2 hours, Filter several times, combine the filtrates, centrifuge while hot (50-60°C), concentrate the supernatant to a relative density of 1.05-1.08 (≤70°C), refrigerate for 12-24 hours, centrifuge, and concentrate the supernatant to a relative density of 1.15 under reduced pressure ~1.23 (≤70°C), then refrigerated for 12~24h, centrifuged, added purified water to the supernatant to 1000ml, stirred well, filtered, and packaged to obtain.
