Condition analysis: Huangqi Shengmai Yin is a kind of Chinese patent medicine, which is evolved from the ancient Chinese medicine Shengmai Powder. The composition of Shengmai Powder is: 9 grams of Codonopsis pilosula, 9 grams of Ophiopogon japonicus, Schisandra chinensis. 6 grams, the dosage should usually be 15-30g with a side of Astragalus. Because it is a patent medicine, it has something to do with the manufacturer's formula. We have no way of knowing. We can only speculate from the original recipe of Shengmai Powder
