中此毒者，不出三十日多死。国中时或吐或泻、以后则肚腹膨胀，不想饮食，口极腥，
甚则额热面红，头面上筋起，如虫行蚓行，或耳鼻内如有一二虫，乃药气冲上，非虫也。或
肚内如蛇翻有声，大便结秘。若酒醉后在酒中受毒者，不独肠脏青黑，即肺、肝、心、脾俱
染黑气，服败毒发毒解毒之药。受毒重则粪黑，受毒轻则粪蓝。若不知解药，则因黑气而变
成黑星，黑星有一颗则肚内如针刺，有十余颗便开成蛇口，如蛇咬状咬上心，出恭泻血，多
不可救。又加以癫药则人多昏愦，又加以肿药，则一耳常满塞，一耳少红浓，如有一二虫行
样。服解药则黑气随粪出，黑气一毫不净，须要戒口。不然一翻，则肠脏内如有数十颗黑星
，如两三只蛇口在肚内咬，而外蛇亦从风而至，病患夜不得卧者。
亦用雄黄末、蒜子、菖蒲捣烂，放热水内，洗身以御外蛇。若在酒内中毒，断不可用酒
罐煨药，犯之必翻，愈翻则毒入愈深。茶内中毒戒茶，病痊后可吃。病重时戒吃太饱，戒生
冷煎炒，戒吃一切补药，戒雨淋湿身湿脚，戒远行，戒忿怒，照后中疳方调治。戒荤盐，每
餐用笋水一茶杯煮菜吃。无力者常煎紫苏、薄荷二味作茶吃，即是要药，或兼田内茨菇菜更
妙。有力者照后苏荷汤四方加减治服。其余所食之物，俱与后中疳篇同。但看食物全不变，
如吃菜屙菜，甚至吃饭则屙成颗饭，则毒净矣。自此以后，过三四日，食物仍变，出恭转黄
，开吃荤盐、生冷、酒醋、煎炒无妨，惟鸡鸭宜戒二年，羊鹅戒三年，鱼虾螺蚌等腥物宜戒
三四年，蛇蛤终身不可食。后中疳篇同此戒口。又水内之物，惟鳖可食无妨。按∶国中一二
日，有吃马肉而愈者。又中蛊者不肯戒荤盐，则饮食中盐宜少放，荤少吃，但戒鸡鸭鱼虾等
物可也。
感染此毒者，不出三十日大多死亡。国内时常出现呕吐或腹泻，随后腹部膨胀，不想饮食，口中极腥臭，
严重时额头发热、面色发红，头面部的筋脉凸起，感觉像虫子爬行或蚯蚓蠕动，有时耳鼻内感觉有一两只虫子在动，这是药气冲逆向上所致，并非真有虫子。或者肚内像蛇翻动有声，大便干结不通。如果在酒醉后在酒中受毒，不仅肠脏呈现青黑色，就连肺、肝、心、脾都染上黑气，需服用败毒、发毒、解毒的药物。中毒重的大便呈黑色，中毒轻的大便呈蓝色。如果不知道解药，则会因黑气而变成黑星，有一颗黑星则肚内如针刺感，有十余颗便张开成蛇口状，像被蛇咬住心脏一样，排便泻血，大多不可救治。如果再误服癫药，人就会神志昏乱；再误服肿药，则一只耳朵常感满塞，另一只耳朵少红且流脓，感觉像有一两只虫子在爬。服用解药后，黑气随粪便排出，若黑气排得不干净，必须严格忌口。否则一旦复发，则肠脏内如有数十颗黑星，像两三只蛇口在肚内撕咬，而外部的蛇毒也会随风而至，患者夜间无法入睡。
也使用雄黄粉、蒜瓣、石菖蒲捣烂，放入热水中，洗澡以抵御“外蛇”。如果在酒内中毒，绝对不可用酒罐煨煮药物，触犯此禁忌必致病情反复，越反复则毒邪深入越深。在茶内中毒要戒茶，病愈后可吃。病重时禁止吃太饱，禁止生冷煎炒食物，禁止吃一切补药，禁止雨水淋湿身体和脚，禁止远行，禁止愤怒，参照后面的中疳方调理治疗。禁止荤腥和盐，每餐用笋水一茶杯煮菜吃。无力者常煎紫苏、薄荷两味药作茶喝，这就是要药，或者兼加田里的茨菇菜更好。有力者参照后面的苏荷汤四方加减服用。其余所吃的食物，都与后面中疳篇相同。只要看食物完全不变，比如吃菜拉出菜，甚至吃饭则拉出颗粒状的饭，说明毒已净。从此以后，过三四天，食物仍变样，排便转黄，开始吃荤腥、盐、生冷、酒醋、煎炒食物无妨，只有鸡鸭宜戒两年，羊鹅戒三年，鱼虾螺蚌等腥物宜戒三四年，蛇蛤终身不可食用。后面中疳篇也是同样的忌口要求。另外水中的食物，只有鳖可食无妨。按：国内一两天内，有吃马肉而痊愈的。又中蛊者不肯戒荤盐，则饮食中盐宜少放，荤少吃，但戒鸡鸭鱼虾等物即可。
Those infected with this poison often die within thirty days. In the region, it is common to experience vomiting or diarrhea, followed by abdominal distension, loss of appetite, and a very fishy odor in the mouth.
In severe cases, the forehead becomes hot and the face red, with veins bulging on the head and face, feeling as if insects are crawling or earthworms moving. Sometimes, one may feel like there are one or two insects inside the nose or ears; this is due to the medicinal qi rushing upward, not actual insects. Alternatively, there may be sounds in the abdomen resembling a snake turning over, accompanied by constipation. If poisoned while drunk in alcohol, not only will the intestines and viscera turn blue-black, but the lungs, liver, heart, and spleen will also be tainted with black qi. One must take medicines that defeat poison, promote toxin expulsion, and detoxify. Severe poisoning results in black stool, while mild poisoning results in blue stool. If the antidote is unknown, the black qi will transform into black spots. With one spot, the abdomen feels like being pricked by needles; with more than ten spots, they open like snake mouths, biting towards the heart like a snake bite, leading to bloody stools, which are mostly incurable. If further administered with mad drugs, the person becomes confused and unconscious; if administered with swelling-inducing drugs, one ear becomes constantly blocked, while the other becomes less red and purulent, feeling like insects crawling. After taking the antidote, the black qi exits with the feces. If any black qi remains impure, strict dietary restrictions are required. Otherwise, upon recurrence, dozens of black spots may appear in the intestines, like two or three snake mouths biting inside the abdomen, and external snake toxins may arrive via wind, causing the patient to be unable to sleep at night.
Also, use realgar powder, garlic cloves, and Acorus tatarinowii (Changpu) mashed and placed in hot water for bathing to ward off "external snakes." If poisoned through alcohol, absolutely do not decoct medicine in an alcohol jar; violating this will cause relapse, making the toxin penetrate deeper. If poisoned through tea, abstain from tea until recovery. When severely ill, avoid overeating, raw/cold/fried foods, all tonics, rain wetting the body and feet, long journeys, and anger. Treat according to the subsequent Zhonggan prescription. Abstain from meat and salt; cook vegetables with one teacup of bamboo shoot water per meal. Those with weak constitutions should frequently decoct Perilla frutescens (Zisu) and Mentha haplocalyx (Bohe) as tea, which are essential herbs, preferably adding wild arrowhead (Cizhu) from fields. Those with strong constitutions should adjust and take the four formulas of Suhe Tang subsequently. Other foods consumed are the same as in the subsequent Zhonggan section. As long as food passes unchanged, such as excreting undigested vegetables or even rice grains after eating rice, the toxin is cleared. Thereafter, after three or four days, when food digestion resumes normally and stools turn yellow, consuming meat, salt, raw/cold items, wine/vinegar, and fried foods is permissible. However, chicken and duck should be avoided for two years, sheep and goose for three years, and fish, shrimp, snails, clams, and other seafood for three to four years. Snakes and frogs must never be eaten for life. The subsequent Zhonggan section has similar dietary restrictions. Among aquatic foods, only soft-shell turtle is safe to eat. Note: In the region, some recovered within one or two days after eating horse meat. Furthermore, those poisoned by Gu who refuse to abstain from meat and salt should reduce salt intake and consume less meat, but must still avoid chicken, duck, fish, and shrimp.
