霍乱之症。急于风雨。心腹绞痛肠胃并结。欲吐不吐。欲下不下。手足挥顿滚转烦闷。
顷刻
之间。而死生安危系焉。盖由平日过伤饮食。多劳多气。一感臭秽。清气混淆。于是阴阳不
调畅。水火不升降。中气溃乱。而病斯剧矣。邪在上则吐。邪在下则泻。邪在中则吐泻兼作
。是皆易治者也。若不吐不泻。则死在旦夕矣。又有转筋霍乱者。缘筋属肝水。脾胃暴败。
则血与气暴截。无所接济。故筋急而转缩矣。此尤霍乱中之至重者也。若吐泻则亦有可治。
倘不吐泻。必死无疑。大抵霍乱初发不得用药。以其气乱。药不能理也。
微而涩或代而散。或隐而伏。或大而虚。洪者为热。弦者为痛。微弱渐绝死。脉渐大者
生。

霍乱这种病症，发作起来比风雨还要急骤。患者心腹剧烈绞痛，肠胃气机郁结阻滞。想要呕吐却吐不出来，想要排泄却又排不出。手足躁动不安，身体翻滚，心中烦闷痛苦。在极短的时间内，生死安危就取决于此了。这大概是因为平日饮食过度损伤，劳累过度，耗伤元气，一旦感受了污秽之气，导致体内清气与浊气混淆。于是阴阳之气不能调和畅达，水火之气不能正常升降，中焦脾胃之气溃乱，从而病情变得严重。邪气在上焦则引起呕吐，邪气在下焦则引起腹泻，邪气在中焦则呕吐和腹泻同时发生。这些情况都是比较容易治疗的。如果不呕吐也不腹泻，那么死亡就在旦夕之间了。又有转筋型霍乱，因为筋脉归属于肝（肝主筋），若脾胃功能突然败坏，则气血骤然被截断，无法相互接济，所以筋脉拘急而发生扭转收缩。这更是霍乱中最为严重的类型。如果是伴有呕吐和腹泻的，还有治愈的可能；倘若既不呕吐也不腹泻，必定无疑会死亡。大抵霍乱初发时不宜立即用药，因为此时患者气机紊乱，药物难以调理。
脉象微细而涩，或出现代脉且散乱，或隐伏难寻，或脉大而虚。脉洪大的属于热证，脉弦的属于痛证。脉微弱逐渐消失的预后不良，多致死亡；脉象逐渐变大的则有生机，预后良好。

Huo Luan (cholera-like syndrome) presents with an onset more sudden than wind and rain. The patient experiences severe, colicky pain in the heart and abdomen, with stagnation and knotting of the intestines and stomach. There is a desire to vomit but inability to do so, and a desire to defecate but inability to do so. The limbs are restless and flailing, the body rolls about, and there is intense mental restlessness and oppression. Life and death hang in the balance within a very short period. This is generally caused by previous overindulgence in diet, excessive labor, and depletion of Qi. Upon exposure to foul or turbid pathogens, the clear Qi becomes confused and mixed. Consequently, Yin and Yang fail to harmonize and flow smoothly, and Water and Fire fail to ascend and descend properly. The Middle Jiao Qi becomes chaotic, leading to severe disease. If the pathogen is in the Upper Jiao, vomiting occurs; if in the Lower Jiao, diarrhea occurs; if in the Middle Jiao, both vomiting and diarrhea occur simultaneously. These conditions are relatively easy to treat. However, if there is neither vomiting nor diarrhea, death may occur at dawn or dusk. There is also a type known as Huo Luan with tendon contraction (spasms). Since tendons belong to the Liver, if the Spleen and Stomach function suddenly fails, Blood and Qi are abruptly cut off from mutual support, causing the tendons to become tight and contract. This is the most critical form of Huo Luan. If vomiting and diarrhea are present, there is still a chance for recovery; if absent, death is certain. Generally, medication should not be administered immediately upon the initial onset of Huo Luan because the Qi is chaotic and drugs cannot effectively regulate it.
The pulse may be faint and choppy, or intermittent and scattered, or hidden and deep, or large and deficient. A flooding pulse indicates Heat; a wiry pulse indicates Pain. A pulse that is faint and gradually disappearing indicates a fatal prognosis; a pulse that gradually becomes larger indicates survival.
