秦子曰∶痰之为病，变化百出，皆内因七情，外感六气，中宫失清化之令，熏蒸结聚而
成，须分所兼之邪治之。有风痰、湿痰、燥痰、郁痰、食积五条。夫湿痰、燥痰，有外感，有内
伤；郁痰、食痰，有内伤，无外感。饮主乎水，寒多热少；痰主乎火，寒少热多。
【风痰之症】头痛身痛，发热恶寒，吐嗽痰沫气逆，此外感风痰症也。
【风痰之因】外感风邪，袭人肌表，束其内郁之火，不得发泄，外邪传里，内外熏蒸
【风痰之脉】浮滑者多。浮数风热；浮紧风寒。若见沉滑，风邪内结。洪大易治，沉
【风痰之治】有风寒、风热之分。外感风寒，宜辛散表邪，如三拗汤，合小半夏汤、

【湿痰之症】身发寒热，面目浮肿，恶寒头重，身痛不能转侧，呕吐恶心，烦满不渴
【湿痰之因】或坐卧卑湿，或冲风冒雨，则湿气袭人，内与身中之水液，交凝积聚，
所云∶风雨袭阴之虚，病起于上而成积；清湿袭阴之虚，病生于下而生聚。此即湿痰之因也
【湿痰之脉】脉多浮大，浮缓兼风，浮涩主湿，浮滑湿痰，沉滑顽结。
【湿痰之治】身热脉浮大者，宜散风除湿，羌活胜湿汤。胸满脉滑者，宜化痰二陈汤、
羌活胜湿汤 散表除湿，则痰自化。

Qin Zi said: The disease of phlegm (Tan, Phlegm) manifests in myriad ways. It is caused by internal factors such as the Seven Emotions (Qi, emotional disorders) and external factors such as the Six Qi (Wind, Cold, Summer-heat, Dampness, Dryness, Fire), leading to the loss of clear transformation functions in the Middle Jiao (Spleen and Stomach). Through steaming and condensation, it forms phlegm. Treatment must be differentiated based on the pathogenic factors involved. There are five main types: Wind-Phlegm, Damp-Phlegm, Dry-Phlegm, Stagnant-Phlegm, and Food Retention. Among these, Damp-Phlegm and Dry-Phlegm can arise from both external contraction and internal injury; Stagnant-Phlegm and Food-Phlegm arise only from internal injury, not from external contraction. Yin (Fluids) is primarily associated with Water, manifesting as more cold and less heat; Tan (Phlegm) is primarily associated with Fire, manifesting as less cold and more heat.
[Symptoms of Wind-Phlegm] Headache and body pain, fever and aversion to cold, vomiting and coughing with frothy sputum and rebellious Qi. This is the syndrome of External Contraction Wind-Phlegm.
[Causes of Wind-Phlegm] External contraction of Wind Pathogen invades the muscle and surface, binding the internally stagnant Fire, preventing its discharge. When the external pathogen transmits inward, internal and external steaming occurs.
[Pulse of Wind-Phlegm] Mostly Floating-Slippery pulse. Floating-Rapid indicates Wind-Heat; Floating-Tight indicates Wind-Cold. If a Deep-Slippery pulse is seen, it indicates Wind Pathogen knotting internally. A Surging-Large pulse is easy to treat; a Deep pulse... [Text cuts off here].
[Treatment of Wind-Phlegm] Differentiated into Wind-Cold and Wind-Heat. For External Contraction Wind-Cold, it is appropriate to use Acrid-Dispersing methods to release the exterior, such as San'ao Decoction combined with Xiao Banxia Decoction.
San'ao Decoction combined with Xiao Banxia Decoction: Treats syndromes such as Wind-Cold phlegm-cough.
Herbs: Ephedrae Herba (Mahuang), Armeniacae Semen Amarum (Xingren), Glycyrrhizae Radix et Rhizoma (Gancao), Pinelliae Rhizoma (Banxia), Zingiberis Rhizoma Recens (Shengjiang).
Xiao Qinglong Decoction: See previous section on Overflowing Fluids.
Shen Su Yin: Treats Wind-Phlegm cough.
Herbs: Ginseng Radix (Renshen), Perillae Folium (Zisu), Peucedani Radix (Qianhu), Puerariae Radix (Gegen), Pinelliae Rhizoma (Banxia), Aurantii Fructus Immaturus (Zhike), Platycodonis Radix (Jiegeng), Citri Reticulatae Pericarpium (Guangpi), Glycyrrhizae Radix et Rhizoma (Gancao).
Add Perillae Fructus (Suzi) and Citri Reticulatae Pericarpium (Juhong) for rebellious Qi. Add Pinelliae Rhizoma (Banxia) and Arisaematis Rhizoma (Nanxing) for excessive phlegm. Add Perillae Fructus (Suzi) and Peucedani Radix (Qianhu) for panting.
Jing Fang Gan Jie Tang: Treats Wind-Heat phlegm-cough.
Herbs: Schizonepetae Spica (Jingjie), Saposhnikoviae Radix (Fangfeng), Platycodonis Radix (Jiegeng), Glycyrrhizae Radix et Rhizoma (Gancao), Menthae Haplocalycis Herba (Bohe).
Jing Fang Xie Bai San: Treats Wind-Heat entering the Lung, Lung-Wind phlegm-panting.
Herbs: Schizonepetae Spica (Jingjie), Saposhnikoviae Radix (Fangfeng), Morus Cortex (Sangbaipi), Lycii Cortex (Digupi), Glycyrrhizae Radix et Rhizoma (Gancao).
[Symptoms of Damp-Phlegm] Body alternating chills and fever, edema of face and eyes, aversion to cold, heavy head, body pain with inability to turn or lie sideways, vomiting, nausea, irritability, fullness, and lack of thirst.
[Causes of Damp-Phlegm] Sitting or lying in damp places, or venturing out in wind and rain, allows Dampness to invade the body. It interacts with the body's fluids, coagulating and accumulating. As stated: "Wind and Rain attack the deficiency of Yin, causing disease to arise from above and form masses; Clear Dampness attacks the deficiency of Yin, causing disease to arise from below and form accumulations." This is the cause of Damp-Phlegm.
[Pulse of Damp-Phlegm] Pulse is mostly Floating-Large. Floating-Slow indicates Wind; Floating-Choppy indicates Dampness; Floating-Slippery indicates Damp-Phlegm; Deep-Slippery indicates stubborn knotting.
[Treatment of Damp-Phlegm] For body heat and Floating-Large pulse, it is appropriate to disperse Wind and eliminate Dampness using Qiang Huo Sheng Shi Tang. For chest fullness and Slippery pulse, it is appropriate to resolve phlegm using Er Chen Tang.
Qiang Huo Sheng Shi Tang: Releases the exterior and eliminates dampness, so phlegm transforms naturally.
