必观其色之白与黄而辨之∶黄者，火将退也。白者，火正炽也。正炽者，用寒凉之品，将退者，用祛逐之味。
今一方而俱治，方用∶
白术（三钱） 茯苓（五钱） 陈皮（一钱） 甘草（一钱） 白芥子（三钱） 枳壳（五分）
水煎服。
有火加栀子，无火不必加也。此方健脾去湿，治痰在中焦者也。
又方∶
白术（五钱） 茯苓（五钱） 薏仁（五钱） 陈皮（一钱） 天花粉（二钱） 益智仁（三分） 人参（三分）
水煎服。
有火加黄芩一钱，无火加干姜耶、甘草二分。此方健脾去湿而不耗气，二剂而痰自消也。
久病之痰，切不可作脾湿生痰论之。盖久病不愈，未有不因肾水亏损者也。非肾水泛上为痰，即肾火沸腾为
痰。当补肾以祛逐之，方用∶
熟地（一两） 山萸（五钱） 薏仁（一两） 山药（五钱） 芡实（五钱）
麦冬（五钱） 五味子（三钱） 茯苓（三钱） 车前子（一钱） 益智仁（二钱）
水煎服。
此治水泛为痰之圣药也。若火沸为痰者，加肉桂一钱。此方补肾去湿而化痰，水入肾宫，自变为真精而不化
痰矣。此治下焦有痰之法也。
又方∶
久病之痰，方用六味地黄汤加麦冬、五味子，实有奇功。无火加附子、肉桂可耳。
夫痰之滞，乃气之滞也。苟不补气而惟去其痰，未见痰去而病消也。方用∶
人参（一钱） 白术（二钱） 茯苓（三钱） 陈皮（一钱） 白芥子（一钱） 花粉（一钱） 苏子（八分）
豆蔻（三粒）
水煎服。
〔此方之妙，在于治痰之中而理其气。气顺则痰活，气顺则湿流而痰不生矣。此气治之宜知。〕
必须观察痰液的颜色是白色还是黄色来进行辨别：颜色发黄，说明火热之势即将消退；颜色发白，说明火热正处于炽盛阶段。对于火热正炽盛的，使用寒凉性质的药物；对于火热即将消退的，使用祛除痰浊的药物。
现在用一个方子同时兼顾治疗，方剂组成如下：
白术（三钱） 茯苓（五钱） 陈皮（一钱） 甘草（一钱） 白芥子（三钱） 枳壳（五分）
用水煎煮后服用。
如果有火邪，加栀子；如果没有火邪，不必加。这个方子能健脾祛湿，专门治疗中焦部位的痰证。
另一个方子：
白术（五钱） 茯苓（五钱） 薏仁（五钱） 陈皮（一钱） 天花粉（二钱） 益智仁（三分） 人参（三分）
用水煎煮后服用。
如果有火邪，加黄芩一钱；如果没有火邪，加干姜二分、甘草二分。这个方子能健脾祛湿而不耗伤正气，服用两剂后痰自然消除。
久病产生的痰，切不可简单地按照脾虚湿盛生痰来论述。因为久病不愈，没有不是因为肾水亏损导致的。如果不是肾水泛滥上行化为痰，就是肾火沸腾上炎化为痰。应当通过补肾的方法来祛除痰浊，方剂组成如下：
熟地黄（一两） 山茱萸（五钱） 薏仁（一两） 山药（五钱） 芡实（五钱）
麦冬（五钱） 五味子（三钱） 茯苓（三钱） 车前子（一钱） 益智仁（二钱）
用水煎煮后服用。
这是治疗因水泛为痰的圣药。如果是因火沸为痰的情况，加肉桂一钱。这个方子能补肾祛湿并化痰，使水液进入肾宫后，自然转化为真精而不再化为痰。这是治疗下焦有痰的方法。
另一个方子：
治疗久病之痰，使用六味地黄汤（Six-Ingredient Rehmannia Pill）加入麦冬、五味子，确实有奇效。如果没有火邪，加入附子、肉桂即可。
所谓痰的停滞，实际上是气的停滞。如果不补气而只去除痰，未见痰去而病消的情况。方剂组成如下：
人参（一钱） 白术（二钱） 茯苓（三钱） 陈皮（一钱） 白芥子（一钱） 花粉（一钱） 苏子（八分）
豆蔻（三粒）
用水煎煮后服用。
〔此方的妙处，在于治痰的同时调理气机。气顺则痰活，气顺则湿气流动而痰不再产生。这是调治气机的要点，应当知晓。〕
One must observe whether the sputum is white or yellow to differentiate it: Yellow indicates that the fire pathogen is about to subside; white indicates that the fire pathogen is currently blazing. For cases where the fire is blazing, cold and cool-natured herbs should be used; for cases where the fire is subsiding, herbs that dispel phlegm should be used.
Now, a single formula is employed to treat both simultaneously. The formula consists of:
Bai Zhu (Atractylodis Rhizoma) [3 qian], Fu Ling (Poria) [5 qian], Chen Pi (Citri Reticulatae Pericarpium) [1 qian], Gan Cao (Glycyrrhizae Radix et Rhizoma) [1 qian], Bai Jie Zi (Sinapis Semen) [3 qian], Zhi Qiao (Aurantii Fructus Immaturus) [5 fen].
Decoct in water and take orally.
If there is fire, add Zhi Zi (Gardeniae Fructus); if there is no fire, do not add it. This formula strengthens the Spleen and eliminates dampness, treating phlegm located in the Middle Jiao.
Another formula:
Bai Zhu (Atractylodis Rhizoma) [5 qian], Fu Ling (Poria) [5 qian], Yi Ren (Coicis Semen) [5 qian], Chen Pi (Citri Reticulatae Pericarpium) [1 qian], Tian Hua Fen (Trichosanthis Radix) [2 qian], Yi Zhi Ren (Alpiniae Oxyphyllae Fructus) [3 fen], Ren Shen (Ginseng Radix et Rhizoma) [3 fen].
Decoct in water and take orally.
If there is fire, add Huang Qin (Scutellariae Radix) [1 qian]; if there is no fire, add Gan Jiang (Zingiberis Rhizoma) [2 fen] and Gan Cao (Glycyrrhizae Radix et Rhizoma) [2 fen]. This formula strengthens the Spleen and eliminates dampness without consuming Qi. After two doses, the phlegm will naturally dissipate.
Phlegm resulting from chronic illness must not simply be attributed to Spleen deficiency generating dampness and phlegm. Chronic illness that fails to resolve invariably stems from Kidney Yin (Kidney Water) depletion. It is either Kidney Water flooding upward transforming into phlegm, or Kidney Fire boiling upward transforming into phlegm. Treatment should focus on tonifying the Kidney to dispel phlegm. The formula consists of:
Shu Di Huang (Rehmanniae Radix Praeparata) [1 liang], Shan Yu Rou (Corni Fructus) [5 qian], Yi Ren (Coicis Semen) [1 liang], Shan Yao (Dioscoreae Rhizoma) [5 qian], Qian Shi (Euryales Semen) [5 qian], Mai Dong (Ophiopogonis Radix) [5 qian], Wu Wei Zi (Schisandrae Fructus) [3 qian], Fu Ling (Poria) [3 qian], Che Qian Zi (Plantaginis Semen) [1 qian], Yi Zhi Ren (Alpiniae Oxyphyllae Fructus) [2 qian].
Decoct in water and take orally.
This is a sacred remedy for treating phlegm caused by water flooding. If the phlegm is caused by boiling fire, add Rou Gui (Cinnamomi Cortex) [1 qian]. This formula tonifies the Kidney, eliminates dampness, and transforms phlegm. When the water enters the Kidney Palace, it naturally transforms into True Essence rather than becoming phlegm. This is the method for treating phlegm in the Lower Jiao.
Another formula:
For phlegm due to chronic illness, Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) added with Mai Dong (Ophiopogonis Radix) and Wu Wei Zi (Schisandrae Fructus) yields remarkable results. If there is no fire, adding Fu Zi (Aconiti Lateralis Radix Praeparata) and Rou Gui (Cinnamomi Cortex) suffices.
The stagnation of phlegm is essentially the stagnation of Qi. If one does not tonify Qi but only attempts to remove phlegm, it is unlikely that the phlegm will disperse while the disease resolves. The formula consists of:
Ren Shen (Ginseng Radix et Rhizoma) [1 qian], Bai Zhu (Atractylodis Rhizoma) [2 qian], Fu Ling (Poria) [3 qian], Chen Pi (Citri Reticulatae Pericarpium) [1 qian], Bai Jie Zi (Sinapis Semen) [1 qian], Hua Fen (Trichosanthis Radix) [1 qian], Su Zi (Perillae Fructus) [8 fen], Dou Kou (Cardamomi Fructus) [3 grains].
Decoct in water and take orally.
[The brilliance of this formula lies in regulating Qi while treating phlegm. When Qi flows smoothly, phlegm becomes active and mobile; when Qi flows smoothly, dampness circulates freely and phlegm ceases to form. This principle of regulating Qi should be understood.]
