体象 滑脉替替，往来流利；盘珠之形，荷露之义。
滑者，往来流利而不涩滞也。故如盘中之走珠，荷叶之承露，形容其旋转轻脱之状。
主病 左寸滑者，心经痰热。滑在左关，头目为患。左尺得滑，茎痛尿赤。右寸滑者，痰饮呕逆。
滑在右关，宿食不化。右尺得滑，溺血经郁。
滑脉势不安定，鼓荡流利，似近于阳，故曰阳中之阴。不腐不化之物，象亦如之，故主痰液有物之类为
多。心主高拱，百邪莫犯，如使痰入包络，未免震邻。东风生于春，病在肝，目者肝之窍，肝风内鼓则热生，
邪害空窍。肾气通于前阴，膀胱火迫，故茎痛尿赤。肺有客邪，积为痰饮，则气不宣扬而成呕逆。食滞于
胃，脉必紧盛；滑则相近于紧，故脾胃见之，知其宿食。右尺火部，滑为太过，血受火迫而随溺出；经郁者，
非停痰则气滞血壅相与为病耳。
兼脉 浮滑风痰，沉滑痰食。滑数痰火，滑短气塞。滑而浮大，尿则阴痛。滑而浮散，中风瘫缓。
滑而冲和，娠孕可决。
鼓动浮越，风之象也，故滑而浮者兼风。沉下结滞，食之征也，故滑而沉者兼食。热则生痰，故流利之间
而至数加以急疾。郁则气滞，故圆转之际还呈短缩。浮大者膀胱火炽，尿乃作疼。浮散者风淫气虚，行
坐不遂。滑伯仁曰∶“三部脉浮沉正等，无他病而不月者，为有妊也。”故滑而冲和，此血来养胎之兆。夫
脉者，血之府也，血盛则脉滑，故妊孕宜之。
凡痰饮、呕逆、伤食等证，皆上中二焦之病，以滑为水物兼有之象也。设所吐之物非痰与食，是为呕逆，
脉必见涩也。溺血、经闭或主淋痢者，咸内有所蓄，血积类液，瘀凝类痰，须以意求耳。
按《素问·诊要经终篇》曰∶“滑者，阴气有余；阴气有余，故多汗身寒。”伪诀云∶“胃家有寒，下焦蓄血，
脐下如冰。”与经旨未全违背，第不知变通，禅家所谓死于句下。仲景以“翕、奄、沉”三字状滑脉者，翕
者合也，奄者忽也，当脉气合聚而盛之时，奄忽之间，即以沉去，摩写往来流利之状，极为曲至。又曰∶
“沉为纯阴，翕为正阳，阴阳和合，故令脉滑，关尺自平。”此言无病之滑脉也。若云∶“阳明脉微沉者，当
阳部见阴脉，则阴偏胜而阳不足也。少阴脉微滑者，当阴部见阳脉，则阳偏胜而阴不足也。三部九候，
各自不同。”伪诀云∶“按之即伏，不进不退”，是不分浮滑、沉滑、尺寸之滑矣。仲景恐人误认滑脉为
沉，下文又曰∶“滑者，紧之浮名也。”则知沉为翕奄之沉，非重取乃得一定之沉也。而伪诀云“按之即
伏”，与翕奄之沉，何啻千里；云“不进不退”，与滑之象尤为不合。夫血盛则脉滑，故肾脉宜之；气盛则
脉滑，故肺脉宜之。此皆滑中之平脉。叔和言“关滑胃热”，乃指与数相似，正《内经》所云“诸过者切
之”之滑也。要之兼浮者毗于阳，兼沉者毗于阴，是以或寒或热，从无定称；惟衡之以浮沉，辨之以尺
寸，始无误耳。故善于读书，则如伪诀“胃家有寒”诸说，亦可通之于经；不善读书，《内经》“阴气有余”
一语，适足以成刻舟求剑之弊。脉岂易言也哉！
【体象】
滑脉跳动有力，往来流畅；其形态如同盘中滚动的珠子，其意蕴好比荷叶上承托的露珠。
所谓“滑”，是指脉搏往来流利而没有涩滞感。因此用盘子里滚动的珍珠、荷叶上承接的露水来形容它旋转轻灵、脱洒流畅的状态。
【主病】
左寸部出现滑脉，是心经有痰热之邪。
滑脉出现在左关部，头部和眼睛会发生病变。
左尺部出现滑脉，会出现阴茎疼痛、小便色赤的症状。
右寸部出现滑脉，是痰饮停聚引起的呕吐逆气。
滑脉出现在右关部，是宿食停滞不消化。
右尺部出现滑脉，会出现尿血或月经郁滞不通。
滑脉气势不安定，鼓荡且流利，似乎接近阳脉的特征，所以被称为“阳中之阴”。那些腐败不化之物，其形象也与此相似，所以滑脉主要主痰液等有形实邪的病症居多。
心位居高，百邪难犯，但如果痰邪侵入心包络，就会引起惊悸震动。东风生于春季，风邪致病多在肝脏，眼睛是肝的窍穴，肝风内动则生热，邪气侵害空窍。肾气通向前阴，膀胱火邪逼迫，所以出现阴茎疼痛、小便色赤。肺受外来邪气侵袭，积聚成为痰饮，导致肺气不能宣发肃降而引发呕吐逆气。食物停滞在胃中，脉象必然紧盛；滑脉与紧脉相近，所以脾胃部位见到滑脉，就知道是宿食停滞。右尺部属火，滑脉表示火气太过，血液受热逼迫随尿液排出；月经郁滞不通，如果不是停痰，就是气滞血瘀相互为患。
【兼脉】
浮滑脉主风痰，沉滑脉主痰食。
滑数脉主痰火，滑短脉主气机阻塞。
滑而浮大的脉象，排尿时阴部疼痛。
滑而浮散的脉象，主中风导致的肢体瘫痪缓纵。
滑而冲和（柔和）的脉象，可以判断为妊娠。
鼓动浮越，是风的征象，所以滑脉兼见浮脉则兼夹风邪。沉下结滞，是食的征象，所以滑脉兼见沉脉则兼夹食积。热邪会产生痰，所以在流利之中至数（脉搏跳动频率）加快。气机郁滞，所以在圆转之中还呈现短缩之象。浮大脉表示膀胱火炽盛，排尿因而作痛。浮散脉表示风邪淫溢、正气虚弱，行走坐立不便。滑伯仁说：“三部脉浮沉力度相当，没有其它疾病但月经停止的，是有身孕的表现。”所以滑脉兼见冲和之气，这是血液来滋养胎元的征兆。脉是血液的府库，血盛则脉滑，所以妊娠适宜见到这种脉象。
凡是痰饮、呕吐逆气、伤食等证候，都是上焦和中焦的疾病，因为滑脉是水湿之物兼有的脉象。如果所吐出的东西不是痰和食物，而是单纯的呕吐逆气，脉象必然表现为涩脉。尿血、闭经或主诉淋证痢疾的，都是因为体内有所蓄积，血积类似液体，瘀凝类似痰浊，需要用心推求辨析。
按《素问·诊要经终篇》说：“滑脉，是阴气有余；阴气有余，所以多汗且身体寒冷。”伪诀（指非经典的伪托之作）说：“胃家有寒，下焦蓄血，脐下感觉像冰一样冷。”这与经典旨意并未完全违背，只是不知道变通，禅宗所说的“死于句下”（拘泥于文字表面）。张仲景用“翕、奄、沉”三个字来描述滑脉，“翕”是合聚的意思，“奄”是忽然的意思，当脉气合聚而盛大之时，忽然之间，脉势就以沉去的方式表现，描绘出往来流利的状态，极为细致周到。又说：“沉代表纯阴，翕代表正阳，阴阳和合，所以使脉象滑利，关部和尺部的脉气自然平和。”这是说无病之人的正常滑脉。如果说：“阳明脉微沉，是在阳部见到阴脉，则是阴偏胜而阳不足。少阴脉微滑，是在阴部见到阳脉，则是阳偏胜而阴不足。三部九候，各自不同。”伪诀说：“重按即伏，不进也不退”，这是不分浮滑、沉滑以及尺寸各部滑脉的区别。张仲景恐怕人们误将滑脉认作沉脉，下文又说：“滑脉，是紧脉的浮取名称。”由此可知，这里的“沉”是指翕奄那种忽聚忽散的沉，而不是重取才能得到的固定不变的沉脉。而伪诀说“重按即伏”，与翕奄之沉相差千里；说“不进不退”，与滑脉的形象尤为不合。血盛则脉滑，所以肾脉适宜见到滑脉；气盛则脉滑，所以肺脉适宜见到滑脉。这些都是滑脉中的平脉（正常脉）。王叔和说“关部滑脉主胃热”，是指与数脉相似的情况，正是《内经》所说的“诸过者切之”（各种异常脉象需仔细切诊）中的滑脉。总之，兼见浮脉的偏向于阳，兼见沉脉的偏向于阴，所以或寒或热，没有固定的称呼；只有权衡以浮沉，辨别以尺寸，才不会出错。所以善于读书的人，对于伪诀中“胃家有寒”等说法，也可以将其贯通于经典之中；不善于读书的人，《内经》中“阴气有余”这一句话，恰恰足以造成刻舟求剑的弊端。脉学难道容易言说吗！
[Body and Image]
The Hua (Slippery) pulse beats vigorously, flowing smoothly in both directions; its form resembles pearls rolling in a plate, and its meaning is like dew resting on lotus leaves.
"Hua" refers to the pulse flowing smoothly without any roughness or stagnation. Therefore, it is described as moving pearls in a plate or dew supported by lotus leaves, depicting its rotating, light, and agile nature.
[Primary Diseases]
A Hua pulse at the Left Cun position indicates Phlegm-Heat in the Heart Meridian.
A Hua pulse at the Left Guan position suggests disorders of the head and eyes.
A Hua pulse at the Left Chi position indicates pain in the penis and reddish urine.
A Hua pulse at the Right Cun position indicates vomiting and reflux due to retained Phlegm-Fluids.
A Hua pulse at the Right Guan position indicates undigested food retention.
A Hua pulse at the Right Chi position indicates hematuria or menstrual stagnation.
The momentum of the Hua pulse is unstable, surging and smooth; although it appears close to Yang characteristics, it is termed "Yin within Yang." Substances that are unrotten and undigested share this image, so the Hua pulse primarily governs conditions involving tangible pathogens such as phlegm fluids.
The Heart resides high, making it difficult for pathogens to invade; however, if Phlegm enters the Pericardium, it causes palpitations and agitation. East wind arises in Spring, causing disease in the Liver; the eyes are the orifices of the Liver, and internal stirring of Liver-Wind generates Heat, with pathogenic factors harming the orifices. Kidney Qi connects to the anterior yin; bladder Fire forces the pathogen, resulting in penile pain and reddish urine. The Lung is invaded by external pathogens, accumulating into Phlegm-Fluids, leading to failure of Lung Qi to disseminate and descend, causing vomiting and reflux. Food stagnates in the Stomach, and the pulse must be Tight and vigorous; since Hua is similar to Tight, seeing Hua at the Spleen and Stomach positions indicates food retention. The Right Chi position belongs to Fire; Hua indicates excessive Fire, forcing blood to exit with urine; menstrual stagnation, if not caused by retained Phlegm, results from Qi stagnation and Blood stasis interacting to cause disease.
[Combined Pulses]
Floating-Hua indicates Wind-Phlegm; Sunken-Hua indicates Phlegm-Food.
Hua-Shu (Rapid) indicates Phlegm-Fire; Hua-Duan (Short) indicates Qi obstruction.
Hua and Floating-Large indicate pain in the yin during urination.
Hua and Floating-Scattered indicate stroke with flaccid paralysis.
Hua and Chonghe (Harmonious/Soft) can determine pregnancy.
Surging and floating represent the image of Wind; thus, Hua combined with Floating indicates concurrent Wind. Sunken and stagnant represent the sign of Food; thus, Hua combined with Sunken indicates concurrent Food retention. Heat generates Phlegm, so between the smooth flow, the frequency accelerates. Stagnation causes Qi blockage, so amidst the circular movement, shortness appears. Floating-Large indicates blazing Bladder Fire, causing pain during urination. Floating-Scattered indicates Wind excess and Qi deficiency, leading to difficulty in walking and sitting. Hu Bo-ren stated: "If the pulses at the three positions are equal in depth and strength, with no other illness but amenorrhea, it indicates pregnancy." Therefore, Hua combined with harmonious qualities is a sign of blood nourishing the fetus. The pulse is the residence of Blood; when Blood is abundant, the pulse is Hua, which is suitable for pregnancy.
Conditions such as Phlegm-Fluids, vomiting/reflux, and food injury are diseases of the Upper and Middle Jiao, as Hua is the image associated with water-damp substances. If the vomitus is neither phlegm nor food, but simple reflux, the pulse will necessarily appear Se (Choppy). Hematuria, amenorrhea, or conditions presenting as strangury/dysentery all imply internal accumulation; blood stasis resembles fluid, and coagulation resembles phlegm, requiring careful mental deduction.
According to the *Su Wen · Zhen Yao Jing Zhong Pian*: "Hua indicates excess Yin-Qi; excess Yin-Qi leads to profuse sweating and cold body." The False Formula states: "Cold in the Stomach house, blood accumulation in the Lower Jiao, feeling like ice below the umbilicus." This does not completely contradict the classic intent, but lacks flexibility, akin to the Chan Buddhist concept of "dying under the sentence" (being trapped by literal interpretation). Zhang Zhongjing used the characters "Xi, Yan, Chen" to describe the Hua pulse. "Xi" means gathering; "Yan" means suddenly. When Qi gathers and becomes vigorous, it suddenly sinks away, depicting the flowing smoothness with great precision. He further stated: "Chen represents pure Yin, Xi represents correct Yang; Yin and Yang harmonize, causing the pulse to be Hua, keeping the Guan and Chi positions balanced." This describes the normal Hua pulse in a healthy person. It is said: "Yangming pulse slightly sunken indicates Yin appearing in Yang positions, meaning Yin prevails and Yang is insufficient. Shaoyin pulse slightly Hua indicates Yang appearing in Yin positions, meaning Yang prevails and Yin is insufficient. The Three Parts and Nine Positions differ individually." The False Formula states: "Pressing down makes it vanish, neither advancing nor retreating," failing to distinguish between Floating-Hua, Sunken-Hua, and Hua at different positions. Zhang Zhongjing feared people might mistake Hua for Chen, so he added: "Hua is the floating name of Tight." Thus, the "Chen" here refers to the sudden gathering/sinking of Xi/Yan, not a fixed Chen obtained only by heavy pressure. The False Formula's "vanishes upon pressing" differs from Xi/Yan Chen by miles; "neither advancing nor retreating" contradicts the image of Hua significantly. Abundant Blood makes the pulse Hua, suitable for the Kidney pulse; abundant Qi makes the pulse Hua, suitable for the Lung pulse. These are normal Hua pulses. Wang Shuhe's statement "Guan Hua indicates Stomach Heat" refers to similarity with Shu (Rapid), which aligns with the *Nei Jing*'s instruction to carefully palpate "various abnormalities." In summary, Hua combined with Floating leans toward Yang, while Hua combined with Sunken leans toward Yin; thus, it may be Cold or Hot, with no fixed designation; only by weighing Floating/Sunken and distinguishing Cun/Chi can errors be avoided. Therefore, a good reader can reconcile the False Formula's "Cold in the Stomach" with the Classics; a poor reader, relying solely on the *Nei Jing*'s "excess Yin-Qi," commits the error of carving a mark on a moving boat. How difficult is pulse diagnosis!
