胃气则生，无胃气则死，缓之于脉大矣哉！是故缓脉不主疾病，惟考其兼见之脉，乃可断其为病耳。岐伯曰∶“
脾者土也，孤脏以灌四旁者也。善者不可见，恶者可见。其来如水之流者，此为太过，病在外；如乌之
喙，此谓不及，病在中。太过则令人四肢沉重；不及则令人九窍壅塞不通。”王叔和《脉经》云∶“脾旺之

反得沉濡而滑者，是肾之乘脾，水之凌土，为微邪，虽病即瘥。”高阳生伪诀以缓脉主脾热、口臭、反胃、齿痛、
梦鬼诸症，出自杜撰，与缓脉无涉也。
【体象】缓脉的脉率是一息四至，往来从容均匀；其形态如同微风轻拂柳枝，又似初春时节杨柳随风摇曳。
【兼脉主病】缓脉代表胃气，本身并不主病。只有结合其他兼见的脉象，才能判断病症。浮缓脉主风邪伤表，沉缓脉主寒湿内侵。缓而大者主大风虚损，缓而细者主湿痹。缓而涩者主脾气薄弱，缓而弱者主气虚。左寸部见涩缓脉，主少阴血虚。右寸部见浮缓脉，主风邪停留。左关部见浮缓脉，主肝风内动。右关部见沉缓脉，主脾土虚弱、湿气侵袭。左尺部见缓涩脉，主肾精不足。右尺部见缓细脉，主真阳极度衰微。
【按语】缓脉以宽舒和缓为含义，与紧脉正好相反。在八卦中对应坤卦，在五行中属土，在时令上对应四季之末（长夏），在人体中对应足太阴脾经。如果寸部属阳、尺部属阴，上下脉势同等，脉形浮大而柔软，没有偏盛偏衰的情况，这是平和之脉。所以说，缓脉若和匀，不浮不沉，不大不小，不快不慢，神意欣欣向荣，从容自得，难以用言语形容的，这就是真正的胃气脉。又说，土是万物的母亲，中焦之气调和，则百病不生。另外，一切脉象中都必须带有缓象，这称为胃气；如果只见到本脏的脉象，而没有胃气来调和它，就会出现真脏脉，预示生命将尽。又说，有胃气则生，无胃气则死，缓脉对于诊脉来说意义重大！因此缓脉本身不主疾病，只有考察其兼见的脉象，才能判断是否为病。岐伯说：“脾属土，是孤脏，负责灌溉四方脏腑。功能正常时表现不明显，功能异常时才会显现。脉来如水流动般急迫，这是太过，病在体表；脉来如乌喙般坚劲，这是不及，病在体内。太过会导致四肢沉重；不及会导致九窍壅塞不通。”王叔和在《脉经》中说：“脾旺之时，脉象宏大，和阿徐缓，称为平脉。如果反而得到弦细而长的脉，这是肝木乘袭脾土，木克土，属于贼邪，病情危重难治。如果反而得到浮涩而短的脉，这是肺金乘袭脾土，子扶母，属于实邪，虽然生病但能自愈。如果反而得到洪大而散的脉，这是心火乘袭脾土，母归子，属于虚邪，虽然生病但容易治愈。如果反而得到沉濡而滑的脉，这是肾水乘袭脾土，水凌土，属于微邪，虽然生病很快就能痊愈。”高阳生的伪托诀书中认为缓脉主脾热、口臭、反胃、齿痛、梦鬼等症状，这些都是凭空捏造的，与缓脉无关。
[Body and Image] The slow pulse (Huan Mai) beats four times per respiration, moving with a calm and even rhythm; its form is like a gentle breeze brushing against willow branches, resembling the swaying of willows in early spring.
[Combined Pulses and Disease Manifestations] The slow pulse represents Stomach Qi (Wei Qi) and does not primarily indicate disease on its own. Only by examining combined pulses can one diagnose the condition. A floating-slow pulse indicates wind pathogen injuring the exterior; a deep-slow pulse indicates cold-dampness invading internally. A large-slow pulse indicates deficiency due to severe wind; a thin-slow pulse indicates damp-bi syndrome. A coarse-slow pulse indicates weak Spleen Qi; a weak-slow pulse indicates Qi deficiency. A coarse-slow pulse at the left Cun position indicates Blood deficiency of the Shaoyin channel. A floating-slow pulse at the right Cun position indicates the residence of wind pathogen. A floating-slow pulse at the left Guan position indicates internal stirring of Liver Wind. A deep-slow pulse at the right Guan position indicates weakness of Earth (Spleen) and invasion by dampness. A slow-coarse pulse at the left Chi position indicates insufficiency of the Essence Palace (Kidney). A slow-thin pulse at the right Chi position indicates extreme decline of True Yang.
[Commentary] The slow pulse signifies breadth, comfort, and moderation, which is exactly opposite to the tight pulse (Jin Mai). In the Eight Trigrams, it corresponds to Kun; in the Five Elements, it belongs to Earth; in seasonal timing, it corresponds to the end of each season (Late Summer); in the human body, it corresponds to the Foot-Taiyin Spleen Meridian. If the Yang Cun and Yin Chi positions are equal in strength, appearing floating, large, and soft without any excess or deficiency, this is a harmonious pulse. Therefore, it is said that when the slow pulse is even and balanced, neither floating nor deep, neither large nor small, neither rapid nor sluggish, with a spirit of vitality and leisurely ease that is difficult to describe, this is the true Stomach Qi pulse. It is also stated that Earth is the mother of all things; if the Middle Jiao Qi is harmonized, hundred diseases will not arise. Furthermore, all types of pulses must contain the element of slowness, which is called Stomach Qi; if only the pulse of the Zang organ itself is seen without the harmonizing influence of Stomach Qi, the True Zang pulse will appear, indicating a short life expectancy. It is also said: "With Stomach Qi, there is life; without Stomach Qi, there is death." Thus, the significance of the slow pulse in pulse diagnosis is profound! Therefore, the slow pulse itself does not indicate disease; only by investigating the combined pulses can one determine the pathology. Qibo stated: "The Spleen belongs to Earth, an isolated Zang organ that irrigates the four directions. When functioning well, its signs are not visible; when malfunctioning, signs become apparent. If the pulse comes flowing like water, this indicates Excess, and the disease is external; if the pulse feels hard like a bird's beak, this indicates Deficiency, and the disease is internal. Excess causes heaviness in the four limbs; Deficiency causes obstruction and blockage of the nine orifices." Wang Shuhe in the *Mai Jing* (Pulse Classic) stated: "During the time when the Spleen is prosperous, the pulse is large, gentle, and slow, named as the Normal Pulse. If instead a string-taut, thin, and long pulse is obtained, this is the Liver Wood overacting on Spleen Earth, Wood overcoming Earth, known as 'Thief Evil' (Zei Xie), which is fatal and untreatable. If instead a floating, coarse, and short pulse is obtained, this is the Lung Metal overacting on Spleen Earth, Child supporting Mother, known as 'Solid Evil' (Shi Xie); although ill, recovery will occur spontaneously. If instead a surging, large, and scattered pulse is obtained, this is the Heart Fire overacting on Spleen Earth, Mother returning to Child, known as 'Deficient Evil' (Xu Xie); although ill, it is easy to treat. If instead a deep, soft, and slippery pulse is obtained, this is the Kidney Water overacting on Spleen Earth, Water flooding Earth, known as 'Minor Evil' (Wei Xie); although ill, it will heal quickly." Gao Yangsheng's pseudo-apocryphal verses claim that the slow pulse governs symptoms such as Spleen heat, bad breath, regurgitation, toothache, and dreaming of ghosts; these are fabricated and unrelated to the slow pulse.
