Embodiment 1

[0032] 1. Take 1 kg of American ginseng and cut it into thin slices, boil it with 5 times the volume of 60% ethanol until it boils slightly for 4 hours, filter the solution and collect the filter residue.

[0033] 2. Boil the filter residue with 15 times of water for 2 hours, collect the solution, repeat this process once, and combine the extracts.

[0034] 3. Concentrate the extract under reduced pressure to a volume of 1 liter.

[0035] 4. Add 4 volumes of 95% ethanol to the extract, stir evenly and let stand overnight at 4°C. The next day, the precipitate was centrifuged, and the precipitate was washed twice with absolute ethanol and then dried under reduced pressure to obtain a powdered American ginseng polysaccharide extract.
