Treatment for all types of phlegm-fluid retention.
Chenpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma).
Add two zhong of water and three slices of Shengjiang (Zingiberis Rhizoma Recens), decoct until eight-tenths remain, take after meals.

Wang Yinjun's Mengshi Gun Tan Wan (Calamine Pill for Rolling Down Phlegm), summarized as follows:
Turning over in the steamer, armor hangs on gold,
Now the head is deep in the thatched hall.
Meeting at two-eight, seek the correct jin weight,
Xiao (Sal Nitri) and Qingmengshi (Calamine) double, if heavy like Chenxiang (Agarwood).
Seventeen taels plus half a tael,
Water pills sized like sophora seeds, always measured carefully.
Thousand strange diseases respond like divine efficacy,
But it cannot bear alone the case of watery diarrhea.
Dahuang (Rhei Radix et Rhizoma, steamed with wine), Huangqin (Scutellariae Radix, washed with wine, each 8 liang), Chenxiang (Aquilariae Lignum Resinatum, 5 qian), Mengshi (Calamine, calcined, 1 liang).
Grind the above into powder, mix with clear water to form pills the size of mung beans. Take 50-60 pills each time, swallowed with boiling plain water.
This medicine uses Huangqin (Scutellariae Radix) and Dahuang (Rhei Radix et Rhizoma) to severely purge damp-heat from yin and yang; Mengshi (Calamine) is used to sink phlegm; Chenxiang (Aquilariae Lignum Resinatum) guides the qi of all organs upward to heaven and downward to springs, serving as the guiding herb.
