数脉主腑，主吐主狂。有力为热，无力为疮。
数脉为阳，六腑亦为阳，故主腑。《难经》九难曰∶数者府也。又曰∶数则
为热。《伤寒论》亦曰∶数为在府。此以迟数分阴阳，故即以配脏腑，亦不可言其大
概耳。至若错综互见，在腑有迟，在脏有数，在表有迟，在里有数，又安可以脏腑
二字拘定也。数脉主吐者，脉始于中焦，吐则胃气逆，中焦扰乱，气逆而动，故脉
数。（宜六君子汤、生姜、竹茹、茱连之类。）主狂者，狂则神志昏乱，气无所御。气无所御，则
奔逸于四肢，而四肢实。四肢实，是以能登高行远，跳跃异常。夫四肢为诸阳之本，
阳邪实之，故力倍也。《难经》二十难曰∶重阳者狂。又病能论曰∶狂生于阳也。又
曰∶阳明者常动，巨阳少阳不动，不动而动大疾，此其候也。盖言阳明之脉常动，
巨阳、少阳之脉不动。今无论常动者，即不动者亦动，动且大疾，是为狂病之候。
观此，则狂病之见数脉明矣。（宜东垣朱砂安神丸、集验龙脑安神丸之类。）数而有力，聚热所鼓。
（有外感证者宜汗散∶仲景有汗者桂枝汤、无汗者麻黄汤之类，无外感者，和剂凉膈散、芩连栀柏
之类。）数而无力，虽有热而虚散。热散于外，发疮之候也。（宜黄连解毒汤、消肿汤、当归饮子之类。）
数脉主要对应腑病，主呕吐和狂证。脉象有力属于热证，无力则多属疮疡。
数脉属阳，六腑也属阳，所以数脉主腑病。《难经·九难》说：“数脉对应腑。”又说：“数脉代表热。”《伤寒论》也说：“数脉表示病在腑。”这是以迟脉和数脉来区分阴阳，因此将其与脏腑相对应，但这也不能说是绝对的概括。至于脉象错综复杂、相互兼见的情况，在腑病中可见迟脉，在脏病中可见数脉，在表证中可见迟脉，在里证中可见数脉，又怎能仅仅用“腑”或“脏”这两个字来拘泥限定呢？
数脉主呕吐，是因为脉气起始于中焦，呕吐时胃气上逆，导致中焦紊乱，气机逆乱而搏动加速，所以出现数脉。（适宜使用六君子汤、生姜、竹茹、黄连配吴茱萸等药物。）
数脉主狂证，是因为发狂时神志昏乱，气机失去统摄。气机失去统摄，就会奔逸到四肢，导致四肢充实有力。四肢充实有力，所以能够登高走远，跳跃动作异常。四肢是诸阳经的根本，阳邪充实其中，所以力量加倍。《难经·二十难》说：“重阳者发狂。”《素问·病能论》说：“狂证产生于阳。”又说：“阳明脉常跳动，巨阳脉和少阳脉不跳动，如果不跳动的脉反而跳动且急促，这就是狂证的征象。”这意思是说阳明脉经常跳动，而巨阳脉和少阳脉通常不跳动。现在无论是否平时跳动的脉，连平时不跳动的脉也跳动了，而且跳动大而急，这就是狂病的征候。观察这一点，那么狂病出现数脉就是很明显的了。（适宜使用东垣朱砂安神丸、集验龙脑安神丸等方剂。）
数脉且有力，是热邪积聚鼓动所致。（如果有外感症状的应当使用发汗解表法：张仲景记载，有汗出的用桂枝汤，无汗出的用麻黄汤等；如果没有外感症状的，可使用《太平惠民和剂局方》凉膈散、黄芩、黄连、栀子、黄柏等清热药。）
数脉且无力，虽然也有热，但是正气虚散。热邪散发于体表，是发生疮疡的征候。（适宜使用黄连解毒汤、消肿汤、当归饮子等方剂。）
The rapid pulse (Shu Mai, 数脉) primarily corresponds to Fu-organ diseases, and is indicative of vomiting and mania. A forceful rapid pulse indicates heat, while a feeble one suggests sores or ulcers.
The rapid pulse belongs to Yang, and the six Fu organs also belong to Yang; therefore, the rapid pulse governs Fu-organ conditions. *Nan Jing* (Classic of Difficult Issues), Chapter 9, states: "Rapid [pulse] corresponds to the Fu organs." It further states: "Rapid [pulse] indicates heat." The *Shanghan Lun* (Treatise on Cold Damage) also says: "Rapid [pulse] signifies disease in the Fu organs." This classification uses slow and rapid pulses to distinguish Yin and Yang, thereby associating them with Zang and Fu organs; however, this cannot be regarded as an absolute generalization. In cases where pulse patterns are complex and intermingled, a slow pulse may appear in Fu-organ diseases, a rapid pulse in Zang-organ diseases, a slow pulse in exterior syndromes, and a rapid pulse in interior syndromes. How can one rigidly confine these phenomena merely to the concepts of "Fu" or "Zang"?
The rapid pulse indicating vomiting arises because the pulse qi originates in the Middle Jiao (Middle Burner). Vomiting causes Stomach Qi to rebel upward, disrupting the Middle Jiao. The rebellious Qi moves vigorously, resulting in a rapid pulse. (Treatment should include Liu Junzi Tang [Six Gentlemen Decoction], Shengjiang [Fresh Ginger Rhizome], Zhuru [Bamboo Shavings], and combinations such as Huanglian [Coptis Rhizome] with Zhuyu [Evodia Fruit].)
The rapid pulse indicating mania occurs because during mania, the spirit and mind become confused, and Qi loses its control. When Qi is uncontrolled, it rushes to the four limbs, causing them to become full and solid. Because the four limbs are full and solid, the patient is able to climb high, walk far, and jump abnormally. The four limbs are the root of all Yang meridians; when Yang pathogenic factors fill them, strength is doubled. *Nan Jing*, Chapter 20, states: "Excess Yang leads to mania." The *Suwen* (Basic Questions), chapter "Bing Neng Lun," states: "Mania arises from Yang." It further states: "The Yangming meridian is constantly pulsating, whereas the Juyang [Taiyang] and Shaoyang meridians do not normally pulsate. If the non-pulsating meridians begin to pulsate rapidly and forcefully, this is the sign of mania." This implies that the Yangming meridian normally pulsates, while the Taiyang and Shaoyang meridians do not. Now, regardless of whether they normally pulsate, even those that do not are pulsating, and the pulsation is large and rapid; this constitutes the manifestation of mania. Observing this, it is clear why the rapid pulse appears in mania. (Treatment should include Zhu Sha Anshen Wan [Cinnabar Calming the Spirit Pill] by Li Dongyuan, or Jiyan Long Nao Anshen Wan [Collected Efficacy Dragon Brain Calming the Spirit Pill].)
A rapid pulse that is forceful indicates heat accumulating and driving the pulse. (If exterior syndrome signs are present, sweating and dispersing methods should be used: Zhang Zhongjing recommends Guizhi Tang [Cinnamon Twig Decoction] for patients with sweating, and Mahuang Tang [Ephedra Decoction] for those without sweating. For patients without exterior syndromes, Liangge San [Cooling the Chest Powder] from the *Heji Ju Fang* [Formulas of the Bureau of Medical Relief], or herbs such as Huangqin [Scutellaria Root], Huanglian [Coptis Rhizome], Zhizi [Gardenia Fruit], and Huangbai [Phellodendron Bark] should be used.)
A rapid pulse that is feeble indicates heat accompanied by deficiency and dispersion. Heat dissipating to the exterior is a sign of developing sores or ulcers. (Treatment should include Huanglian Jiedu Tang [Coptis Decoction for Resolving Toxicity], Xiaozhong Tang [Reduce Swelling Decoction], or Danggui Yinzi [Angelica Drink].)
