痧毒侵犯胃部，导致蛔虫死亡并进入大肠，与宿存的粪便结合，引起腹部剧烈疼痛，这被称为“蛔结”。
治疗案例：
有一位朱子佩的女儿，痧症发作时疼痛极其剧烈，头部出汗如雨下。请我诊治，脉象芤而洪实，放痧未能排出病邪，刮痧也无效果。使用细辛大黄丸微冷服用，又用荆芥银花汤稍冷服用。三天后，痧筋显现，进行放痧处理。继续按之前的方法服药，但腹痛仍未停止。到了第十九天，每日用药中加大黄用量，大便排出了三条死蛔虫和结块的粪便，但疼痛依然不止。此时又出现痧筋，再次放痧，服用之前的药物，病情才痊愈。
痧毒侵入脏腑之气，导致气机闭塞不通，向上攻冲至三阳经的巅顶部位，因此疼痛深入脑髓，出现头晕沉重、不省人事的症状，名为“真头痛”。早晨发病傍晚死亡，傍晚发病次日清晨死亡。急救时应刺破巅顶，放出毒血以泄除邪气，药物治疗主要以破除毒瓦斯、清理脏腑为主。若痧毒侵入脏腑之血，导致血液壅滞瘀阻不能流通，向上冲犯三阳经的头面肌肉，因此出现肌肉肿胀、眼睛闭合、耳朵堵塞、心胸烦闷等症状。急救时应刺破巅顶及各处青筋（静脉），放出毒血。药物治疗应以清理血分、破除壅阻为关键。
治疗案例：
张显如，头痛且伴有头晕沉重感，六脉皆伏。针刺巅顶一针，其余痧筋全部刺破，患者稍见清醒。复诊时脉象沉实且上达鱼际，使用清气化痰饮，冷服后病情安定。
汪路真的妻子，头面部红肿，发热头痛，心胸迷闷。诊脉，脉象芤而疾速。针刺左腿弯处三针，血流如注。冷服半杯红花膏子，再用蒲黄饮服用三剂而痊愈。
痧毒冲犯心脏，属于气分病变，则表现为疼痛时作时止，痰涎壅盛，昏迷烦闷，这是其症状表现，治疗宜针刺手臂，以服用顺气药剂为主。若痧毒攻心，属于血分病变，则表现为剧烈疼痛不止，昏沉不醒，这是其症状表现。治疗宜针刺腿弯，以服用活血药剂为主。若延误时机则难以救治。
治疗案例：
郑延旦的次子，心中突然剧痛，口吐痰涎，迷闷无法出声。请我诊治，两寸脉沉而伏，关尺脉洪而紧。针刺痧筋二十针，使用乌药顺气汤，冷冻饮料服用四剂后病情安定。
严瑞宇的三女儿，吃饭时心中突然剧痛，昏沉不醒。傍晚请我诊治，六脉已绝，我推辞未治，次日患者去世。
Sha toxin attacks the stomach, causing roundworms to die and enter the large intestine, where they bind with retained feces, resulting in severe abdominal pain; this is termed "Roundworm Obstruction" (Hui Jie).
Clinical Case:
A daughter of Zhu Ziping suffered from an outbreak of Sha disease with extreme pain and profuse sweating on the head. Upon my examination, her pulse was Kou (hollow) yet Hong (surging) and solid. Bloodletting failed to expel the pathogen, and Gua Sha (scraping therapy) yielded no results. I prescribed Xixin Dahuang Wan (Asarum and Rhubarb Pill) to be taken slightly cold, followed by Jingjie Yinhua Tang (Schizonepeta and Honeysuckle Decoction) also taken slightly cold. Three days later, Sha Jin (visible subcutaneous veins) appeared, and bloodletting was performed. Medication continued as before, but abdominal pain persisted. By the nineteenth day, the dosage of Dahuang (Rhubarb Root and Rhizome) was increased daily. Three dead roundworms and bound feces were passed in the stool, yet the pain remained unrelieved. Sha Jin appeared again, and bloodletting was repeated. After taking the previous medication, she recovered.
When Sha toxin invades the Qi of the Zang-Fu organs, it causes obstruction and blockage, attacking upward to the vertex (Dian Ding), which belongs to the Three Yang meridians. Consequently, pain penetrates into the brain marrow, accompanied by dizziness, heaviness, and loss of consciousness; this is named "True Headache" (Zhen Tou Tong). If onset occurs in the morning, death follows by evening; if in the evening, death follows by morning. Emergency treatment requires puncturing the vertex to release toxic blood and vent the pathogenic Qi. Pharmacological treatment should focus on breaking down toxic vapors and clearing the Zang-Fu organs. When Sha toxin invades the Blood of the Zang-Fu organs, it causes stagnation and瘀 (stasis), preventing flow, and rushes upward to the muscles of the head and face along the Three Yang meridians. This results in muscle swelling, closed eyes, blocked ears, and chest oppression. Emergency treatment involves puncturing the vertex and various blue veins (Qing Jin) to release toxic blood. Pharmacological treatment should prioritize clearing the Blood level and breaking down stagnation.
Clinical Case:
Zhang Xianru presented with headache, dizziness, and a sense of heaviness; all six pulses were Fu (deep and hidden). One needle was inserted at the vertex, and all visible Sha Jin were pricked. The patient showed slight improvement. On follow-up, the pulse was Chen (deep) and Shi (solid), reaching up to the Yu Ji area. Qingqi Huatan Yin (Clear Qi and Transform Phlegm Drink) was administered cold, bringing stability.
The wife of Wang Luzhen exhibited redness and swelling of the head and face, fever, headache, and mental confusion/chest oppression. Her pulse was Kou and Ji (rapid). Three needles were inserted at the popliteal fossa of the left leg, resulting in profuse bleeding. Half a cup of Honghua Gaozi (Safflower Paste) was taken cold, followed by three doses of Puhuang Yin (Cattail Pollen Drink), leading to recovery.
When Sha toxin rushes to the Heart and affects the Qi level, symptoms include intermittent pain, abundant phlegm-saliva, coma, and irritability. Treatment should primarily involve needling the arms and administering Qi-regulating formulas. When Sha toxin attacks the Heart and affects the Blood level, symptoms include unremitting severe pain, stupor, and unconsciousness. Treatment should primarily involve needling the popliteal fossa and administering Blood-invigorating formulas. Delayed treatment makes rescue difficult.
Clinical Case:
The second son of Zheng Yandan experienced sudden severe epigastric/cardiac pain, vomiting of phlegm-saliva, and inability to speak due to confusion. Examination revealed that the Cun positions of both wrists were Chen and Fu, while the Guan and Chi positions were Hong and Jin. Twenty needles were inserted into Sha Jin. Wuyao Shunqi Tang (Lindera Regulating Qi Decoction) was administered as a chilled drink for four doses, resulting in stabilization.
The third daughter of Yan Ruiyu experienced sudden severe cardiac pain during meals, followed by stupor and unconsciousness. She was consulted in the evening, but all six pulses had vanished. I declined treatment, and she passed away the following day.
