咳嗽多浮，聚胃关肺。沉紧小危，浮濡易治。
咳嗽不一，强半为风寒痰饮，风寒则伤于皮毛。（宜汗解，如麻黄汤、参苏饮之类。）痰饮
则停于胸胃。（宜二陈汤、仲景小青龙汤、拔萃半夏温肺汤之类。）皮毛者，肺之合也，邪袭其合，肺
气应之，故上逆而为咳。胃居肺下，寒痰冷冻饮料，停滞于中，上射于肺，肺气迎之，
故亦上逆而为咳。经云∶形寒饮冷则伤肺。（痰饮寒浊之气，上熏于肺，肺不清净，咳嗽从生。）形寒
固伤于外，而冷冻饮料寒痰，则皆聚于胃也。肺居最上，皮毛最表，故脉多浮耳。沉紧
小危者，沉则邪入里，紧则寒不散，小则正气衰，均主病危。若浮而濡，浮则在表，濡受邪轻，故云易治。

咳嗽的脉象多呈浮象，病机关键在于痰饮聚于胃、邪气关乎肺。脉象若见沉、紧、小则预示病情危重；若见浮、濡则易于治疗。
咳嗽病因多样，其中大半由风寒和痰饮引起。若是风寒之邪，则损伤皮毛。（适宜采用发汗解表法治疗，如使用麻黄汤、参苏饮等方剂。）若是痰饮之邪，则停滞在胸膈和胃脘。（适宜使用二陈汤、张仲景的小青龙汤、拔萃半夏温肺汤等方剂。）皮毛是肺的外合部位，外邪侵袭其合部，肺气随之感应失调，因此气机上逆而引发咳嗽。胃位于肺之下，寒性的痰饮或冷冻饮料停滞在中焦，向上熏射于肺，肺气与之相迎拒，因此也导致气机上逆而引发咳嗽。《内经》说：形体受寒、饮食生冷会损伤肺脏。（这是因为痰饮寒浊之气上熏于肺，使肺失清肃洁净，从而产生咳嗽。）形体受寒固然伤及体表，而冷冻饮料形成的寒痰，则都聚集于胃中。肺位居人体最上部，皮毛位于最表层，所以脉象多表现为浮象。脉象沉、紧、小之所以主危，是因为沉表示邪气入里，紧表示寒邪未散，小表示正气衰败，这些都主病势危重。如果脉象浮而濡，浮表示病邪在表，濡表示受邪轻微，所以说容易治疗。

Coughing pulses are mostly floating; the pathology centers on phlegm-fluids gathering in the Stomach and the pathogen affecting the Lung. Pulses that are deep, tight, or small indicate a critical condition, whereas those that are floating and soggy are easy to treat.
Causes of coughing vary, but more than half are due to Wind-Cold and Phlegm-Fluids. If caused by Wind-Cold, it injures the skin and hair (Treatment should induce sweating to resolve the exterior, such as using Mahuang Tang [Ephedra Decoction] or Shensu Yin [Ginseng and Perilla Leaf Drink].). If caused by Phlegm-Fluids, they stagnate in the chest and epigastrium (Treatment should employ Erchen Tang [Two-Chen Decoction], Zhang Zhongjing's Xiao Qinglong Tang [Minor Blue Dragon Decoction], or Bcui Banxia Wenfei Tang [Extracts Extracting Pinellia Warming Lung Decoction].). The skin and hair are the external correspondence of the Lung; when pathogens invade this correspondence, the Lung Qi responds accordingly, leading to rebellious upward flow and causing cough. The Stomach is located below the Lung; cold phlegm and frozen drinks stagnate in the middle jiao and shoot upward to the Lung. When Lung Qi meets this rebellion, it also leads to upward reversal and causes cough. The Classics state: "Coldness of the form and cold drinks injure the Lung." (This is because the turbid qi of cold phlegm and fluids steams upward to the Lung, making the Lung impure and unclean, from which cough arises.) Coldness of the form certainly injures the exterior, while frozen drinks forming cold phlegm all gather in the Stomach. The Lung resides at the highest position, and the skin and hair are at the most superficial level; therefore, the pulse is mostly floating. A pulse that is deep, tight, and small indicates danger because deep signifies the pathogen has entered the interior, tight signifies cold has not dispersed, and small signifies the righteous qi is depleted; all these indicate a critical illness. If the pulse is floating and soggy, floating indicates the pathogen is in the exterior, and soggy indicates the pathogenic invasion is mild; thus, it is said to be easy to treat.

Shensu Yin Treats phlegm accumulation in the Zhongwan (CV12), dizziness, gastric discomfort, palpitations, hiccups, or phlegm stagnation in the joints causing limb dragging, facial paralysis (deviation of mouth and eye), hemiplegia, vomiting, nausea, headache, fever, as well as symptoms of Wind-Cold invasion such as nasal congestion, aversion to cold, and cough.

Frequent salivation and drooling, spontaneous flow of clear water from the mouth, urgent distending pain in the hypochondrium, and loss of appetite. This is caused by deficiency-cold of the Stomach Qi. The pulse is deep, wiry, fine, and slow.
