麦门冬七升 半夏一升 人参三两 甘草二两 大枣十二枚 粳米三合
半夏之性，用入温燥药中则燥，用入清润药中，则下气而化痰。胃气开通，逆火自降，与徒用清寒者，真有霄壤之
别。
当归 白芍 熟地一钱 天冬 麦冬 栝蒌各八分 桃仁（研） 红花五分
生津养血，本润燥之正法。但桃仁、红花虽云活血，恐其破血耳。
黄 一钱五分 苍术（炒）一钱 白术（炒） 陈皮 泽泻五分 人参 茯苓 升麻三
分当归（酒洗） 生地 麦冬 甘草（炙） 神曲（炒） 黄柏（酒炒） 猪苓二分 柴
胡黄连（炒）一分 五味子九粒
每服五钱
方名清燥汤，而所用之药，乃有二术、陈皮、黄柏、神曲等。以此清燥，非抱薪救火乎？
不知此症之要，全在肺金受湿热之邪一语。盖热为积湿所化，湿不去则热不清，徒用清滋，
留湿即以留热，故毅然用燥湿之品，使湿去而热亦清，此其所以为清燥乎？
当归（酒洗）一钱 生地 熟地 芍药（炒） 黄芩（酒炒） 秦艽一钱 防风 甘草
五分
若大便风秘，便可用秦艽、防风；若大便如常，盒饭减去。风药善走与火铄肺金不宜。
大黄（九蒸九晒）五两 火麻仁 郁李仁（去皮） 山药（酒蒸） 山茱肉 车前子 牛
膝（酒蒸）二两 菟丝子（酒洗） 独活 防风 槟榔 枳壳（麸炒）一两
蜜丸。
此不过因大肠秘结，以之润肠通气耳，乃本方自注∶“久服则可百病皆除。”安有大黄、
槟榔之峻下，而可以常服者乎？
* Mai Men Dong (Ophiopogonis Radix) 7 sheng, Ban Xia (Pinelliae Rhizoma) 1 sheng, Ren Shen (Ginseng Radix) 3 liang, Gan Cao (Glycyrrhizae Radix et Rhizoma) 2 liang, Da Zao (Ziziphi Jujubae Fructus) 12 pieces, Jing Mi (Oryza Sativa Grain) 3 he.
The nature of Ban Xia (Pinelliae Rhizoma), when used in conjunction with warm and drying herbs, manifests dryness; however, when used in conjunction with cooling and moistening herbs, it descends qi and resolves phlegm. With the stomach qi unblocked, rebellious fire naturally subsides. This stands in stark contrast to merely using cold-natured herbs.
Dang Gui (Angelicae Sinensis Radix), Bai Shao (Paeoniae Radix Alba), Shu Di Huang (Rehmanniae Radix Preparata) each 1 qian; Tian Dong (Asparagi Radix), Mai Men Dong (Ophiopogonis Radix), Gua Lou (Trichosanthis Fructus) each 8 fen; Tao Ren (Persicae Semen, crushed), Hong Hua (Carthami Flos) 5 fen.
Generating fluids and nourishing blood is indeed the correct method for treating dryness. However, although Tao Ren (Persicae Semen) and Hong Hua (Carthami Flos) are said to invigorate blood, there is a fear that they may break blood stasis too aggressively.
Huang Qi (Astragali Membranacei Radix) 1.5 qian; Cang Zhu (Atractylodis Rhizoma, stir-fried) 1 qian; Bai Zhu (Atractylodis Macrocephalae Rhizoma, stir-fried); Chen Pi (Citri Reticulatae Pericarpium); Ze Xie (Alismatis Rhizoma) 5 fen; Ren Shen (Ginseng Radix); Fu Ling (Poria); Sheng Ma (Cimicifugae Rhizoma) 3 fen; Dang Gui (Angelicae Sinensis Radix, wine-washed); Sheng Di Huang (Rehmanniae Radix); Mai Men Dong (Ophiopogonis Radix); Gan Cao (Glycyrrhizae Radix et Rhizoma, honey-fried); Shen Qu (Massa Medicata Fermentata, stir-fried); Huang Bo (Phellodendri Cortex, wine-fried); Zhu Ling (Poria) 2 fen; Chai Hu (Bupleuri Radix); Huang Lian (Coptidis Rhizoma, stir-fried) 1 fen; Wu Wei Zi (Schisandrae Chinensis Fructus) 9 grains.
Take 5 qian per dose.
Although the formula is named Qing Zao Tang (Clear Dryness Decoction), the ingredients include Er Shu (Cang Zhu and Bai Zhu), Chen Pi, Huang Bo, Shen Qu, etc. Using these to "clear dryness" would be akin to carrying firewood to put out a fire.
However, one must not overlook that the key to this condition lies entirely in the phrase "Lung Metal affected by damp-heat pathogen." Heat is transformed from accumulated dampness; if dampness is not removed, heat cannot be cleared. Merely using cooling and cloying/nourishing herbs will retain dampness, which in turn retains heat. Therefore, resolutely using damp-drying herbs removes dampness, and consequently clears heat. This is why it is called "Qing Zao" (Clearing Dryness).
Dang Gui (Angelicae Sinensis Radix, wine-washed) 1 qian; Sheng Di Huang (Rehmanniae Radix); Shu Di Huang (Rehmanniae Radix Preparata); Shao Yao (Paeoniae Radix, stir-fried); Huang Qin (Scutellariae Radix, wine-fried); Qin Jiao (Gentianae Macrophyllae Radix) 1 qian; Fang Feng (Saposhnikoviae Radix); Gan Cao (Glycyrrhizae Radix et Rhizoma) 5 fen.
If constipation is due to wind-mi (wind-induced stagnation), Qin Jiao and Fang Feng can be used; if bowel movements are normal, these two should be reduced or omitted. Wind-dispelling herbs have a penetrating and moving nature, which is unsuitable when fire scorches Lung Metal.
Da Huang (Rhei Radix et Rhizoma, steamed and dried nine times) 5 liang; Huo Ma Ren (Cannabis Seed); Yu Li Ren (Prunus Semen, peeled); Shan Yao (Dioscoreae Rhizoma, steamed in wine); Shan Zhu Rou (Corni Fructus); Che Qian Zi (Plantaginis Semen); Niu Xi (Achyranthis Bidentatae Radix, steamed in wine) 2 liang; Tu Si Zi (Cuscutae Semen, washed in wine); Du Huo (Angelicae Pubescentis Radix); Fang Feng (Saposhnikoviae Radix); Bing Lang (Arecae Semen); Zhi Ke (Aurantii Fructus Immaturus, bran-stir-fried) 1 liang.
Make into honey pills.
This merely addresses large intestine constipation by moistening the intestines and promoting bowel movement. Yet the self-note of this original formula states: "Long-term use can eliminate all diseases." How can harsh purgatives like Da Huang and Bing Lang be taken regularly?
