The *Huangdi Neijing* (Yellow Emperor's Inner Canon) only mentions "accumulated fluid" (Ji Yin), but does not use the term "phlegm syndrome" (Tan Zheng). It was Zhang Zhongjing who first established the name of the "Four Types of Fluid Retention" (Si Yin), among which "Phlegm-Fluid" (Tan Yin) is one. Since then, passed down through generations...

Or due to overwork and fatigue, or due to worry, thinking, excessive alcohol consumption, and sexual indulgence, leading to consumptive diseases, non-wind sudden syncope, etc. Or the pulse appears fine and rapid, with no yang pathogenic factors in the zang organs, accompanied by symptoms such as occasional vomiting, nausea, diarrhea, shortness of breath, and hoarseness. As long as one observes that the patient's form, qi, and disease condition are originally not excess types, they all belong to Deficiency Phlegm (Xu Tan). In such cases, only tonification and regulation should be employed; if attack methods are used instead, danger is inevitable. In summary, the method for treating phlegm is to strengthen the Yuan Qi (Original Qi) day by day, so that phlegm will naturally decrease day by day. Even if there is a small amount of phlegm, it cannot cause harm, and it can even assist stomach qi. If Yuan Qi declines day by day, then water, grain, and body fluids will all turn into phlegm. As soon as it is generated, it is removed; is there anyone who can attack it until it is completely gone while preserving the Yuan Qi unharmed? Therefore, those skilled in treating phlegm are those who can prevent its generation, which is like mending the sky (a metaphor for supreme skill). If one does not distinguish between deficiency and excess, yet desires to attack uniformly, as Wang Yinjun argued that internal and external diseases all arise from phlegm, and using drugs like Gun Tan Wan (Rolling Phlegm Pill) indiscriminately. This shows knowledge only of the present, ignoring future consequences. Various schools' methods for treating phlegm often treat the branch (symptoms); although one should not be rigid, nor should one steal (blindly copy). Listed in detail below.)

(From *Jingui Yaolue*) Treats phlegm-fluid under the heart, with fullness and distension in the chest and hypochondrium, and dizziness.
Fuling (Poria) (4 liang) Guizhi (Cinnamon Twig) Baizhu (Atractylodis Rhizoma) (3 liang) Gancao (Licorice Root) (2 liang).
Phlegm-fluid is a yin pathogen that obstructs and suppresses yang. Using these yang-promoting herbs to transform qi and extend yang is the correct method. The indication here focuses on fullness in the chest and hypochondrium and dizziness; the purport lies in... [Text contains gaps/corruptions].

(From *Ju Fang*. Chenpi (Tangerine Peel) and Banxia (Pinellia Tuber) are valued for being aged, which reduces their drying and dispersing properties, hence the name "Er Chen" (Two Aged Substances).) Treats all diseases caused by phlegm-fluid, including cough, distension, vomiting, nausea, dizziness, and palpitations. (Thick substance is called phlegm; thin substance is called fluid; water-dampness is the root. When combined with fire, it condenses into phlegm and ascends/descends with qi. In the lung, it causes cough; in the stomach, vomiting; in the head, dizziness; in the heart, palpitations; in the back, coldness; in the hypochondrium, distension. Phlegm in the Zhongwan area causes aversion to cold with high fever and headache, resembling exterior syndromes. Over time, it causes tidal cough worsening at night, resembling internal injury from yin-fire. Migratory joint pain resembles wind syndromes, but muscle color remains normal, and the pulse is slippery and irregular, which distinguishes it.)
Banxia (Pinellia Tuber processed with ginger) (2 qian) Chenpi (Citri Reticulatae Pericarpium, white part removed) (1 qian) Fuling (Poria) (1 qian) Gancao (Licorice Root) (5 fen). Decoct with fresh ginger slices. (Ginger can neutralize the toxicity of Banxia.)
For damp-phlegm, add Cangzhu (Atractylodis Rhizoma); for hypochondriac discomfort, add Xiangfu (Cyperi Rhizoma) and Zhiqiao (Aurantii Fructus).
Banxia is acrid and warm, smooth in texture and dry in nature, acting as the Sovereign herb to move water and resolve phlegm. Phlegm arises from qi stagnation; when qi flows smoothly, phlegm descends. (Pang Anchang said: Those skilled in treating phlegm do not... [Text gap]. Therefore, Fuling is used as the Minister herb to leach out dampness. Disharmony in the middle jiao leads to accumulation of phlegm-saliva, so Gancao is used as the Assistant herb to harmonize the middle and tonify earth. (Some say: If there is phlegm with thirst, Banxia should be removed and replaced with Gualou (Trichosanthis Fructus) and Beimu (Fritillariae Bulbus). Wu Hegao said: If thirsty and desiring to drink water, substitution is possible. If thirsty but unable to drink, Banxia is still appropriate despite thirst. This is because dampness is the root and heat is the branch; extreme dampness mimics the transformation of its conqueror, which is not the true image. Note: Beimu is cold and moistening, treating dry-phlegm of the lung. Banxia is warm and drying, treating damp-phlegm of the spleen. Although both resolve phlegm, their cold/warm and dry/moist natures differ greatly. Misapplication causes significant harm; users must be cautious. In cases of blood deficiency with counter-flow of yin-fire injuring the lung, causing turbid fluids and phlegm production instead of blood, this is named Dry-Phlegm (Zao Tan). Moistening agents should be used, such as Dihuang (Rehmanniae Radix), Maidong (Ophiopogonis Radix), and Gouqi (Lycii Fructus), to nourish yin and descend fire, clearing phlegm naturally. Using Er Chen Tang here leads to immediate danger. For cephalalgia with bone pain at the eyebrow temples, wind-dispelling herbs fail, but phlegm-resolving herbs succeed. For red eyes and photophobia, cooling herbs fail, but phlegm-resolving herbs cure. If a person spits copious frothy sputum that is not thick, this is qi deficiency failing to control saliva; diuretics are contraindicated. Use Liu Jun Zi Tang (Six Gentlemen Decoction) plus Yizhiren (Alpiniae Oxyphyllae Semen) 1 qian to secure it.)
Removing Fuling and Gancao yields Chenpi Banxia Tang (Tangerine Peel and Pinellia Decoction). Adding Jiegeng (Platycodonis Radix) yields Jiegeng Banxia Tang. Removing Chenpi and Gancao yields Banxia Fuling Tang, used for water retention... [Text garbled].
