《直指》云∶中蛊之候，面目青黄，力乏身痛，唇口焦干，眉须脱落，烦躁闷瞀，胸腹
痞满，肚胀皮坚，腹中切痛如虫啮，又如虫行，唾吐鲜血，小便淋沥，大便脓血，病患所食
之物，皆变而为虫，侵蚀脏腑，伤甚则死。死则毒瓦斯流注，复染他人，所谓蛊疰。
脉紧数如钗股，弦直而吐甚者，此中蛊毒也。急治之。中蛊脉洪大者，生。微细者，死
。
凡入有蛊之乡，所用饮食，但以犀角搅试。有毒则白沫竦起，无沫即无毒也。若自幼时
食猫肉者，则毒不能为害。
凡中蛊者，但能记何物之中中毒，须终身再不食此物，犯之则毒作。若用药而愈，自后
饮食永不可吃冷，吃冷则蛊毒复生，竟不能救。
《卫生》云∶凡入蛊乡，见人家门限屋梁绝无灰尘，洁净者，其家必蓄蛊，当用心防之
。如不得已吃其饮食，即潜于初下箸时，收藏一片在手，尽吃不妨。少顷，却将手藏之物潜
埋于人行十字路下，则蛊神反于本家作闹，蛊主必反来恳求。或食时让主人先动箸，或明问
主人云∶莫有蛊么？以箸筑桌而后食，如是则蛊皆不能为害。此皆验于蛊乡云。
胸膈痛胀，则毒在上焦，宜吐之。法以热水半盏，投入胆矾末五分，通口服，少顷，以
鹅翎探吐，毒物出尽自愈。或服升麻汤探而吐之，亦妙。
腹痛胀，为毒在下焦，宜泻之。法以郁金末二钱，米汤调下，空腹取泻，恶毒尽为妙。
泻后，以四君子汤，服二三剂调理，慎忌口。
《直指》记载：中蛊的症状，表现为面目青黄，乏力身痛，嘴唇口角焦干，眉毛胡须脱落，烦躁不安且头目昏花，胸腹部痞塞胀满，肚子胀大皮肤紧绷，腹中剧烈疼痛如同被虫咬或虫爬，呕吐鲜血，小便淋漓不畅，大便带有脓血。病人所吃的食物，都会变成虫子，侵蚀脏腑，损伤严重则死亡。死后毒气流注全身，又会传染给他人，这就是所谓的“蛊疰”。
脉象紧数如钗股般坚硬，或弦直且呕吐严重的，这是中了蛊毒。必须紧急治疗。中蛊后脉象洪大的，预后良好；脉象微细的，预后不良（主死）。
凡是进入有蛊的地区，所用的饮食，可以用犀角搅拌测试。如果有毒，就会产生白色的泡沫耸起；如果没有泡沫，就是无毒。如果从小时候就吃猫肉的人，那么蛊毒就不能对他造成伤害。
凡是中蛊的人，只要能记住是吃了什么东西中毒的，就必须终身不再食用此物，否则一旦触犯，毒邪就会发作。如果用药治愈了，此后饮食永远不可吃生冷食物，吃生冷食物则蛊毒会复发，最终无法救治。
《卫生》记载：凡是进入有蛊的地区，看到别人家的门槛和屋梁上完全没有灰尘，非常洁净的，这家人一定饲养蛊，应当用心防备。如果不得已吃了他们的饮食，就在刚放下筷子时，偷偷藏起一片食物在手中，全部吃完也无妨。过了一会儿，再将手中藏的食物偷偷埋在行人十字路口的地下，那么蛊神就会反过来在本家作乱，养蛊的主人必定会反过来恳求原谅。或者在进食时让主人先动筷子，或者直接问主人：“有没有蛊？”用筷子敲击桌子后再进食，这样蛊就不能造成伤害。这些方法都在有蛊的地区验证过。
胸膈部位疼痛胀满，说明毒邪在上焦，适宜采用催吐法。方法是取半盏热水，投入五分胆矾末，一次性服下，过了一会儿，用鹅毛管探喉催吐，将毒物吐尽自然痊愈。或者服用升麻汤来探吐，也很好。
腹部疼痛胀满，说明毒邪在下焦，适宜采用泻下法。方法是取二钱郁金末，用米汤调服，空腹服用以取得泻下效果，将恶毒排尽最好。泻下之后，服用二三剂四君子汤进行调理，注意严格忌口。
The *Zhizhi* text states: The manifestations of Gu poisoning include a bluish-yellow complexion, fatigue and body pain, dry and cracked lips and mouth, loss of eyebrows and beard, irritability with dizziness and confusion, chest and abdominal fullness and stuffiness, abdominal distension with tight skin, severe abdominal pain as if bitten or crawled by insects, vomiting of fresh blood, dribbling urination, and bloody purulent stools. The food consumed by the patient transforms into insects that erode the Zang-Fu organs; severe damage leads to death. Upon death, toxic vapors circulate throughout the body and infect others, a condition known as "Gu Zhu" (Gu Transmission).
A pulse that is tight and rapid like a hairpin shaft, or wiry and straight accompanied by severe vomiting, indicates Gu poison. Urgent treatment is required. A surging and large pulse in Gu poisoning suggests survival; a faint and fine pulse indicates death.
When entering regions where Gu exists, food and drink can be tested with rhinoceros horn (*Rhinocerotis Cornu*). If toxic, white foam will rise vigorously; if no foam appears, it is non-toxic. Individuals who have eaten cat meat since childhood are immune to Gu poison.
For those poisoned by Gu, if one can recall which specific substance caused the poisoning, one must never consume that substance again for life; otherwise, the toxin will reactivate. If cured by medication, cold foods must be strictly avoided thereafter; consumption of cold food will cause the Gu poison to recur, ultimately becoming incurable.
The *Weisheng* text states: When entering Gu-infested areas, observe households where doorsteps and roof beams are completely free of dust and exceptionally clean; such families likely rear Gu, and one should take precautions. If one must eat their food, secretly hide a piece in hand when first placing chopsticks down; eating the rest is safe. Afterward, bury the hidden piece at a pedestrian crossroads. This causes the Gu spirit to disturb the owner's home instead, compelling the Gu master to beg for forgiveness. Alternatively, allow the host to start eating first, or directly ask, "Do you keep Gu?" Tap the table with chopsticks before eating. These methods prevent harm and have been verified in Gu regions.
Pain and distension in the chest and diaphragm indicate toxin in the Upper Jiao (Upper Burner); emesis is indicated. The method involves mixing 5 fen of Vitriolum (*Chalfan*, Alum) into half a cup of hot water, taking it orally, and after a short while, inducing vomiting with a goose feather quill until all toxins are expelled, leading to recovery. Alternatively, administering Shengma Decoction (*Shengma Tang*) to induce vomiting is also effective.
Abdominal pain and distension indicate toxin in the Lower Jiao (Lower Burner); purgation is indicated. The method involves taking 2 qian of Curcuma Aromatica Powder (*Yujin*, Turmeric Rhizome), mixed with rice soup, taken on an empty stomach to induce purgation, aiming to expel all malignant toxins. Following purgation, administer three doses of Sijunzi Decoction (*Sijunzi Tang*, Four Gentlemen Decoction) for regulation, observing strict dietary restrictions.
