Embodiment 1

[0027] Purchase 10 kg of Baiying medicinal material, crush it, pass through a 40-mesh sieve, soak it in 100 kg of 30% edible ethanol for 1 hour, heat it to about 70°C and keep it warm for 70 minutes, release it while it is hot and filter it to obtain the first soaking liquid, and then successively Add 50 kg and 30 kg of 30% edible ethanol to the medicinal dregs in two times, heat it to about 70°C and keep it warm for 60 minutes, release it while it is hot and filter it, and obtain the second and third soaking liquids. The soaking liquids were combined together, and the ethanol was recovered under reduced pressure, and concentrated to about 50 kg, and 100 grams of powdery activated carbon was added, stirred evenly, and allowed to cool. Add clarifier (100 grams each of A and B) under full stirring, let it stand for 18 hours, let it fully precipitate, filter to remove the precipitate, then wash the precipitate with 800 g of water, concentrate all the soaking liquid and put it unde...

Embodiment 2

[0029] Purchase 11 kg of Baiying medicinal materials, crush them, pass through a 40-mesh sieve, soak them in 140 kg of 30% edible ethanol for 1 hour, heat them to about 65°C and keep them warm for 40 minutes, release them while they are hot and filter them to obtain the first soaking liquid, and then successively Add 33 kg and 33 kg of 30% edible ethanol to the medicinal dregs in two times, heat it to about 70°C and keep it warm for 50 minutes, release it while it is hot and filter it, and obtain the second and third soaking liquids. The soaking liquids are combined together, and the ethanol is recovered under reduced pressure and reduced pressure, and concentrated to about 55 kg, and 120 grams of powdery activated carbon is added, stirred evenly, and allowed to cool. Add clarifier (100 grams each of A and B) under full stirring, let it stand for 20 hours, let it fully precipitate, filter to remove the precipitate, then wash the precipitate with 1000 g of water, concentrate all...

Embodiment 3

[0031] Purchase 9 kg of Baiying medicinal materials, crush them, pass through a 40-mesh sieve, soak them in 72 kg of 30% edible ethanol for 1 hour, heat them to about 80°C and keep them warm for 70 minutes, let them out while they are hot and filter them to obtain the first soaking liquid, then successively Add 54 kg and 45 kg of 30% edible ethanol to the medicinal dregs in two times, heat it to about 60°C and keep it warm for 70 minutes, let it out while it is hot and filter it to obtain the second and third soaking liquids. The soaking liquids are combined together, and the ethanol is recovered under reduced pressure and reduced pressure, and concentrated to about 45 kg, and 120 grams of powdery activated carbon is added, stirred evenly, and allowed to cool. Add clarifier (100 grams each of A and B) under full stirring, let it stand for 24 hours, let it fully precipitate, filter to remove the precipitate, then wash the precipitate with 1000 g of water, concentrate all the soa...
