霍乱之候，脉代勿讶。厥逆迟微，是则可怕。
仲景云∶呕吐而复下利，名曰霍乱。（宜仲景通脉四逆汤、理中丸、四逆加人参汤之类。）霍乱者，
挥霍撩乱，不能自持，阴阳乖离，上下亟夺，是时脉或代止，勿惊讶也。乃卒吐暴
下，谷神顿委，暂不接续故耳。若手足厥冷，脉复迟微，是则大为可怕。盖手足为
诸阳之本，迟微为纯阴之脉，阳衰阴盛，真元渐绝之象也。是故暴脱者能渐生。而
渐绝者，又何能暴起哉？（暴脱者，如日中风雨，风雨过而日仍明。渐绝者，如日渐西坠，坠则终
此日矣，九死之证也。设欲用药救治，非附子理中汤、四逆加人参汤之类不可。）
仲景通脉四逆汤 《伤寒论》云；少阴病，下利清谷，里寒外热．手足厥逆，脉微欲
绝，身反不恶寒，其人面赤色，或腹痛、或干呕、或咽痛、或利止脉不出者，通
脉四逆汤主之。今用治霍乱吐利脉不出者亦宜。
甘草（炙，二两） 附子（大者一枚、生用、去皮脐、破八片） 干姜（三两，强人可四两）
上以水三升，煮一升二合，去滓，分温再服。其脉渐出者愈。

附子理中汤（见第十七）
张仲景的生姜半夏汤：《金匮要略》记载：患者胸中感觉像要喘又不喘，像要呕吐又不呕吐，像要干呕又不干呕，胸中烦闷无奈，生姜半夏汤主治。
半夏（半升） 生姜汁（一升）
以上药用水三升，煮半夏取二升药液，加入生姜汁，再煮取一升半药液。放凉至微温，分四次服用。白天服三次，夜间服一次，症状停止后，停服剩余药物。

霍乱的证候，脉象出现代脉不要惊讶。四肢厥冷且脉搏迟而微弱，这才是可怕的。
张仲景说：呕吐而又腹泻，称为霍乱。（适宜使用张仲景的通脉四逆汤、理中丸、四逆加人参汤之类的方剂。）霍乱，是指发病突然，挥霍撩乱，身体不能自主，阴阳之气乖离失和，上下气机急剧耗夺，此时脉象可能出现代止，不要惊讶。这是因为突然剧烈呕吐和暴泻，脾胃之气顿时委顿，暂时无法接续的缘故。如果手足冰冷，脉搏又变得迟而微弱，这才是非常可怕的。因为手足是诸阳经的根本，迟脉和微脉属于纯阴之脉，这是阳气衰微、阴寒盛极，真元逐渐断绝的迹象。所以，突然暴脱的患者还能逐渐恢复生机；而逐渐断绝的患者，又怎么能突然兴起呢？（所谓暴脱，就像中午遇到风雨，风雨过后太阳依然明亮。所谓渐绝，就像太阳逐渐西沉，沉下去这一天就结束了，这是九死一生的证候。如果想用药救治，非附子理中汤、四逆加人参汤之类的方剂不可。）
张仲景的通脉四逆汤：《伤寒论》记载：少阴病，下利排出未消化的食物，里有寒邪外有假热，手足厥冷，脉搏微弱几乎摸不到，身体反而不恶寒，病人面色发红，或者腹痛、或者干呕、或者咽痛、或者腹泻停止但脉搏不出者，通脉四逆汤主治。现在用它治疗霍乱吐泻导致脉搏不出也是适宜的。
甘草（炙，二两） 附子（大者一枚，生用，去皮脐，破成八片） 干姜（三两，体质强壮者可四两）
以上药用水三升，煮取一升二合药液，去渣，分两次温服。脉搏逐渐出现的就会痊愈。

Zhang Zhongjing's Banxia Half Decoction (see Section 20)
Zhang Zhongjing's Shengjiang Banxia Tang (Ginger Pinellia Decoction): The *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet) states: When a patient feels in the chest as if panting but not actually panting, as if vomiting but not actually vomiting, as if retching but not actually retching, and feels restless and helpless in the chest, Shengjiang Banxia Tang is indicated.
Banxia (Pinelliae Rhizoma, half sheng) Shengjiang Zhi (Fresh Ginger Juice, one sheng)
Take three sheng of water, decoct Banxia to obtain two sheng of liquid, add Shengjiang Zhi, and decoct again to obtain one and a half sheng of liquid. Allow to cool slightly, divide into four doses. Administer three times during the day and once at night. Discontinue remaining doses when symptoms cease.
Erchen Tang (Two-Aged Decoction) (see Section 16)
Sijunzi Tang (Four Gentlemen Decoction) (see Section 16)
Liujunzi Tang (Six Gentlemen Decoction) (see Section 16)
Zhang Zhongjing's Lizhong Tang (Regulate the Middle Decoction) (see Section 17)
Huoxiang Anwei San (Agastache Stomach-Calming Powder) (see Section 20)
In the syndrome of Huoluan (Cholera-like Disease), do not be alarmed if the pulse shows Dai Mai (Intermittent Pulse). However, Jue Ni (Cold Extremities) with Chi Wei Mai (Slow and Faint Pulse) is truly frightening.
Zhang Zhongjing said: Vomiting accompanied by diarrhea is named Huoluan. (It is appropriate to use Zhang Zhongjing's Tongmai Sini Tang (Decoction for Reviving the Pulse and Restoring Yang), Lizhong Wan (Regulate the Middle Pill), or Sini Jia Renshen Tang (Sini Decoction with Ginseng), etc.) Huoluan refers to a sudden onset, chaotic and uncontrollable condition, where Yin and Yang are disordered, and Qi is rapidly depleted from above and below. At this time, the pulse may show Dai Mai (Intermittent Pulse); do not be surprised. This is because sudden violent vomiting and explosive diarrhea cause the Gu Shen (Grain Spirit/Spleen-Stomach Qi) to collapse temporarily, unable to connect continuously. If the hands and feet become cold, and the pulse becomes slow and faint, this is greatly frightening. For the hands and feet are the root of all Yang meridians; Slow and Faint pulses belong to Pure Yin. This is a sign of Yang deficiency and Yin excess, indicating that the Zhen Yuan (True Origin/Vital Essence) is gradually perishing. Therefore, those who suffer from sudden Tu Tuo (Violent Collapse) can gradually regain life. But how can those whose essence is gradually perishing suddenly recover? (Sudden collapse is like a storm at noon; after the storm passes, the sun remains bright. Gradual perishing is like the sun setting in the west; once set, the day ends. This is a critical syndrome with nine chances of death. If one wishes to treat it with medicine, non-Tongmai Sini Tang or Sini Jia Renshen Tang will not suffice.)
Zhang Zhongjing's Tongmai Sini Tang (Decoction for Reviving the Pulse and Restoring Yang): The *Shanghan Lun* (Treatise on Cold Damage) states: In Shaoyin Bing (Shaoyin Disease), with diarrhea passing undigested food, interior cold with exterior heat, Jue Ni (Cold Extremities), Mai Wei Yu Jue (Pulse so faint it is about to disappear), the body is actually not aversive to cold, the person has a red complexion, or abdominal pain, or dry heaving, or sore throat, or diarrhea stops but the pulse does not emerge, Tongmai Sini Tang is indicated. It is also suitable for treating Huoluan with vomiting, diarrhea, and absent pulse.
Gancao (Prepared Licorice Root, two liang) Fuzi (One large Aconite Root, raw, skin and umbilicus removed, broken into eight pieces) Ganjiang (Dried Ginger, three liang, four liang for strong individuals)
Take three sheng of water, decoct to obtain one and two tenths sheng of liquid, remove dregs, divide into two warm doses. Recovery occurs when the pulse gradually emerges.
Zhang Zhongjing's Lizhong Wan (Regulate the Middle Pill) (see Section 17)
Zhang Zhongjing's Sini Jia Renshen Tang (Sini Decoction with Ginseng): Treats all syndromes of deficiency-cold, Yang collapse, diarrhea, Jue Ni (Cold Extremities), etc.
Gancao (Prepared Licorice Root, two liang) Ganjiang (Dried Ginger, one and a half liang) Renshen (Ginseng Root, one liang) Fuzi (One Aconite Root, raw, skin removed, broken into eight pieces)
Take three sheng of water, decoct to obtain one and two tenths sheng of liquid, remove dregs, divide into two warm doses. Strong individuals may use one large Fuzi and three liang of Ganjiang.
