脉 脉滑者多痰。脉滑大为痰火。寸口洪滑为痰。右寸浮滑而疾为痰嗽。两关洪滑而细为胃
中湿痰。宜下之。左寸关弦滑为痰厥头痛。关脉滑大者。膈中有痰。宜吐之。病患诸药不效。
两关脉。或伏或大者。痰也。按经云。浮滑为风痰。沉滑为痰气。紧滑为寒痰。或结或伏为

症 按丹溪云∶有热痰。食积痰。风痰。老痰。寒痰。郁痰之异。又云∶诸病寻痰火。痰火生
异症。痰之为物。随气升降。无处不到。王节斋云∶痰属湿。乃津液所化。因风寒湿热之感
。七情饮食所伤。以致气逆浊液。变为痰也。或吐咯上出。或凝滞胸膈。或留聚肠胃。或客
于脉络四肢。随气升降。遍身上下。无处不到。但有新久轻重之殊耳。新而轻者。形色清白
稀薄。气味亦淡。久而重者。黄浊稠粘凝结。咳之难出。渐成恶味。宜详辨之。
治 按节斋云∶痰生于脾胃。宜实脾燥湿为主。又曰痰随气而升。宜顺气为先。分导次之。
盖气升属火。故顺气在于降火。热痰则清之。湿痰则燥之。风痰则散之。郁痰则开之。顽痰

[Pulse]
A slippery pulse (Hua Mai) indicates the presence of phlegm. A large and slippery pulse indicates Phlegm-Fire. A flooding and slippery pulse at the Cun position indicates Phlegm. A floating, slippery, and rapid pulse at the right Cun position indicates Phlegm-Cough. A flooding, slippery, yet thin pulse at both Guan positions indicates Damp-Phlegm in the stomach; purgation is indicated. A wiry and slippery pulse at the left Cun and Guan positions indicates Phlegm-Jue Headache. A large and slippery pulse at the Guan position indicates Phlegm in the diaphragm; emesis is indicated. If a patient responds poorly to various medications, and the pulses at both Guan positions are either hidden (Fu) or excessive, this indicates Phlegm. According to classic texts: a floating and slippery pulse indicates Wind-Phlegm; a deep and slippery pulse indicates Phlegm-Qi; a tight and slippery pulse indicates Cold-Phlegm; a knotted or hidden pulse indicates Stagnant-Phlegm. Additionally, there is the concept of Phlegm-Fluids; an extremely wiry pulse often indicates Fluid retention. A floating, slippery, and tight pulse indicates Phlegm-Cough. If the eyelids and the area beneath them appear dark like gray smoke, this is also a sign of Phlegm.
[Symptoms]
According to Zhu Danxi: Phlegm is categorized into Heat-Phlegm, Food-Stagnation Phlegm, Wind-Phlegm, Old-Phlegm, Cold-Phlegm, and Stagnant-Phlegm. He further stated that many diseases originate from Phlegm-Fire, which can generate diverse symptoms. Phlegm, as a pathological product, moves with the ascending and descending of Qi, reaching every part of the body. Wang Jiezhai stated that Phlegm belongs to Dampness and is transformed from body fluids. It arises from external contraction of Wind, Cold, Damp, or Heat, or from internal injury due to Seven Emotions and improper diet, leading to rebellious Qi and turbid fluids transforming into Phlegm. Phlegm may be vomited or coughed up, stagnate in the chest and diaphragm, accumulate in the intestines and stomach, or lodge in the meridians and limbs. Moving with Qi, it pervades the entire body. The distinction lies only in whether it is new or old, and mild or severe. New and mild cases present as clear, white, thin, and odorless. Long-standing and severe cases present as yellow, turbid, thick, sticky, and difficult to expectorate, eventually developing a foul odor. These must be carefully differentiated.
[Therapeutic Methods]
According to Wang Jiezhai: Phlegm originates in the Spleen and Stomach; treatment should primarily focus on strengthening the Spleen and drying Dampness. Furthermore, since Phlegm ascends with Qi, treatment should first regulate Qi, followed by resolving and guiding out the Phlegm. Since Qi rebellion is associated with Fire, regulating Qi involves subduing Fire. For Heat-Phlegm, clear the heat; for Damp-Phlegm, dry the dampness; for Wind-Phlegm, disperse the wind; for Stagnant-Phlegm, resolve stagnation; for Stubborn-Phlegm, soften hardness; for Food-Stagnation Phlegm, digest food accumulation. Phlegm in the upper jiao is treated with emesis; Phlegm in the middle jiao is treated with purgation. If Middle Qi is deficient, tonify the Middle Qi to transform the Phlegm. Over-aggressive attack will damage Stomach Qi, causing Phlegm to worsen. Practitioners must exercise caution.
