趺阳脉迟而缓胃气如经也趺阳脉浮而数浮则伤胃数则动脾此非本病医特下之所为也营卫内陷其数先微脉反但浮其人
必大便硬气噫而除何以言之本以数脉动脾其数先微故知脾气不治大便硬气噫而除今脉反浮其数改微邪气独留心中则饥邪
热不杀谷潮热发渴数脉当迟缓脉因前后度数如法病者则饥数脉不时则生恶疮也
趺阳脉迟而缓是胃如常也若趺阳脉浮而数非复胃家常脉矣浮则伤胃数则动脾以胃为阳明而主降故数不伤胃浮则气逆
而伤胃脾为太阴而主升故浮不动脾数则阴烁而动脾趺阳脉本迟缓今忽见浮数胃伤而脾动是何以故盖此非胃家本病乃医特
下之所为也若下之而营卫内陷其数先化为微脉之浮数者反但浮而不数是今之浮而数者先为浮而微也其人必大便坚硬气噫
而除何以知之本以脾为阴土数脉最动胃气若浮数先为浮微此不过胃气之弱约结不舒下则粪粒坚小上则气化凝滞而脾气未

脉浮数则邪热独留薰灼脾阴心液稍耗心中则饥心中虽饥却不消食缘此为邪热不杀谷但觉潮热发渴耳盖数非胃家常病脉当

趺阳脉迟而缓,这是胃气处于正常状态(如常经)。如果趺阳脉浮而数,浮脉表示损伤了胃,数脉表示扰动了脾。这并非疾病原本的状态,而是医生误用攻下法所导致的后果。营气和卫气因此内陷。如果原本的数脉先变得微弱,脉象反而只表现为浮,那么病人必定大便干硬,嗳气后症状缓解。为什么这样说呢?本来是因为数脉扰动脾土,如果数脉先变为微脉,就知道是脾气功能失调,导致大便干硬,嗳气后得以缓解。现在脉象反而浮,且数脉改为微脉,邪气独自留存,心中感觉饥饿,但邪热不能消化食物,出现潮热、口渴。数脉本应转为迟缓,如果脉象前后变化符合规律,病人就会感到饥饿并消化食物;如果数脉不时出现,就会产生恶疮。
趺阳脉迟而缓,说明胃气如常。若趺阳脉浮而数,就不再是胃家的常见脉象了。浮脉伤胃,数脉动脾。因为胃属阳明,主降,所以数脉不伤胃,反而是浮脉导致气逆而伤胃;脾属太阴,主升,所以浮脉不动脾,反而是数脉灼伤阴液而动脾。趺阳脉本是迟缓的,现在忽然出现浮数,胃受伤而脾受扰,这是什么原因呢?大概这是因为不是胃家本身的病,而是医生特意使用攻下法造成的。如果经过攻下,营卫之气内陷,原本的数脉先化为微脉,现在的浮数脉反而只浮而不数(即先浮而微)。这个人必定大便坚硬,嗳气后症状解除。怎么知道的呢?本来脾为阴土,数脉最容易扰动胃气。如果浮数先变为浮微,这不过是胃气虚弱,郁结不舒。如果此时攻下,粪便颗粒会坚小,上部气化凝滞,但如果脾气未动,中脘通畅,上下都会痊愈。所以知道如果是脾气不治,会导致便硬、嗳气而除,因为上通则下达。现在脉象反而浮而数,改变了之前的微象,不再是浮微而是浮数,这就意味着脾气被扰动。脉象浮数,邪热独自留存,熏灼脾阴,心液稍耗,心中感觉饥饿。心中虽然饥饿,却不消化食物,原因是邪热不能杀谷(消化食物),只是觉得潮热、发渴罢了。数脉不是胃家的常病脉,应当见到迟缓脉。如果脉象前后复现数脉,符合出入升降的规律,顺应时辰节律,土气冲和,病人就能消化谷物而感到饥饿,这是中气的恢复,而不是邪气独留导致的饥饿。如果数脉扰动脾土,导致精血消亡,危害不小,不仅仅止于热渴,还会不时地产生恶疮。
The Fuyang pulse is slow and moderate, indicating that the Stomach Qi is in its normal state (as per the classic pattern). If the Fuyang pulse is floating and rapid, a floating pulse indicates injury to the Stomach, and a rapid pulse indicates disturbance of the Spleen. This is not the original disease but the result of a physician's inappropriate use of purgation. The Ying (Nutritive) and Wei (Defensive) Qi have sunk inward. If the rapid pulse first becomes faint, and the pulse appears only floating without being rapid, the person will certainly suffer from hard stool, and symptoms will resolve after belching. Why is this? Originally, the rapid pulse disturbs the Spleen Earth. If the rapid pulse first changes to a faint pulse, it indicates dysfunction of the Spleen Qi, leading to hard stool, which resolves after belching. Now, the pulse is instead floating, and the rapid pulse has changed to faint, leaving pathogenic heat alone. The heart feels hungry, but the pathogenic heat cannot digest food, resulting in tidal fever and thirst. A rapid pulse should transform into a slow and moderate one. If the pulse changes before and after according to proper rules, the patient will feel hunger and digest food; if the rapid pulse appears intermittently, malignant sores will arise.
A Fuyang pulse that is slow and moderate indicates that the Stomach Qi is normal. If the Fuyang pulse is floating and rapid, it is no longer the common pulse of the Stomach. Floating injures the Stomach, and rapid disturbs the Spleen. Because the Stomach belongs to Yangming and governs descending, a rapid pulse does not injure the Stomach; rather, a floating pulse causes Qi rebellion and injures the Stomach. The Spleen belongs to Taiyin and governs ascending, so a floating pulse does not disturb the Spleen; rather, a rapid pulse scorches Yin fluids and disturbs the Spleen. The Fuyang pulse is originally slow and moderate; suddenly appearing as floating and rapid means the Stomach is injured and the Spleen is disturbed. What is the reason? It is likely not an inherent disease of the Stomach family but caused by a physician's specific use of purgation. If purgation leads to the sinking of Ying and Wei Qi, the original rapid pulse first transforms into a faint pulse. The current floating-rapid pulse would instead be only floating without rapidity (i.e., first floating and faint). Such a person will certainly have hard stool, and symptoms will resolve after belching. How do we know? Originally, the Spleen is Yin Earth, and a rapid pulse easily disturbs Stomach Qi. If floating-rapid first becomes floating-faint, this is merely weak Stomach Qi, constrained and uncomfortable. If purgation is applied then, feces will be small and hard, upper Qi transformation will stagnate, but if Spleen Qi remains undisturbed, the Middle Jiao will open, and both upper and lower will heal. Thus, knowing that dysfunctional Spleen Qi leads to hard stool and resolution after belaching, because opening above allows descent below. Now, the pulse is instead floating and rapid, changing from faint to floating-rapid, meaning the Spleen Qi is disturbed. Floating and rapid pulses indicate pathogenic heat lingering alone, scorching Spleen Yin and slightly consuming Heart fluids, causing hunger in the heart. Although hungry, food is not digested because pathogenic heat cannot "kill grain" (digest food); there is only a sensation of tidal fever and thirst. A rapid pulse is not a normal pulse for the Stomach; a slow and moderate pulse should be seen. If the pulse returns to rapidity before and after, following the laws of entry/exit and ascent/descent, conforming to time measures, with harmonious Earth Qi, the patient will digest grain and feel hunger. This is the restoration of Central Qi, not hunger caused by lingering pathogenic heat. If a rapid pulse disturbs the Spleen, causing the depletion of essence and blood, the harm is significant, extending beyond mere fever and thirst, leading to intermittent malignant sores.
