头痛。冒暑者吐痢冷冻饮料。若不已。则百脉昏乱。营卫俱虚。冷搏于筋。令人转筋。邪干于胎。
其胎必损。挥霍之间。便成撩乱。故名霍乱也。

回答说：阴阳之气不相顺接，清浊之气相互干扰，气机冲击中焦，这种病称为霍乱。其根本原因在于饱食肉类后，又进食生冷食物，或饮用寒凉浆水，睡在冷席上。风冷之气损伤脾胃，导致各种食物停滞不消，阴阳二气壅滞而不能疏散，交错于中焦，从而变成呕吐和腹泻。邪气位于上部的，先出现心痛然后呕吐；邪气位于下部的，先出现腹痛然后腹泻；心腹都痛，呕吐和腹泻同时发作。兼夹风邪的，身体发热、头痛；感受暑邪的，呕吐和腹泻出冷冻饮料样的东西。如果病情不愈，则百脉昏乱，营气和卫气都虚弱，寒气与筋脉搏结，使人发生转筋（肌肉痉挛）。邪气干扰胎儿，胎儿必然受损。在顷刻之间，便造成扰乱，所以称为霍乱。

Answer: When Yin and Yang Qi fail to flow smoothly, and Clear and Turbid Qi interfere with each other, Qi attacks the Middle Jiao (Middle Burner), this condition is named Huoluan (Vomiting and Diarrhea Syndrome). The root cause lies in overeating pork or meat, followed by consuming raw and cold foods, drinking cold beverages, or sleeping on cold mats. Wind-cold pathogenic factors damage the Spleen and Stomach, causing all ingested food to stagnate and fail to digest. The Qi of Yin and Yang becomes obstructed and fails to disperse, intertwining within the Middle Jiao, transforming into vomiting and dysentery/diarrhea. If the pathogen resides in the Upper Jiao, heart pain precedes vomiting; if it resides in the Lower Jiao, abdominal pain precedes diarrhea. If both heart and abdomen are painful, vomiting and diarrhea occur simultaneously. Cases complicated by Wind present with fever and headache; cases complicated by Summer-heat present with vomiting and diarrhea resembling frozen drinks. If left untreated, the hundred vessels become chaotic, and both Ying (Nutritive) and Wei (Defensive) Qi become deficient. Cold combats the sinews, leading to muscle spasms (Zhuanjin). If the pathogen interferes with the fetus, the fetus will surely be damaged. In a moment of turmoil, chaos ensues, hence the name Huoluan.
