天津刘××，年三十二岁，于季夏得温热病，兼呕吐不受饮食。
病因 因在校中宿卧，一日因校中无人，其衾褥被人窃去，追之
不及，因努力奔跑，周身出汗，乘凉歇息，遂得斯病。
证候 心中烦热，周身时时汗出，自第二日，呕吐不受饮食。今已四日，屡次服药亦皆吐出，即
渴时饮水亦恒吐出。舌苔白浓，大便四日未行。其脉左部弦硬，右部弦长有力，一息五至。
诊断 其脉左部弦硬者，肝胆之火炽盛也。右部弦长者，冲气挟胃气上冲也。弦长而兼有力者，
外感之热已入阳明之府也。此证因被盗怒动肝气，肝火上冲，并激动冲气挟胃气亦上冲，而外感之热又
复炽盛于胃中以相助为虐，是以烦热汗出不受饮食而吐药吐水也。此当投以清热镇逆之剂。
处方 生石膏（二两细末） 生赭石（六钱细末） 镜面朱砂（五钱细末）
和匀分作五包，先送服一包，过两点钟再送服一包，病愈即停服，不必尽剂。方用散剂不用汤
剂者止呕吐之药丸散优于汤剂也。
效果 服至两包，呕吐已愈，心中犹觉烦热。服至四包，烦热全愈，大便亦通下矣。
帮助 石膏为石质之药，本重坠且又寒凉，是以白虎汤中以石膏
为主，而以甘草缓之，以粳米和之，欲其服后留恋于胃中，不至速于下行。故用石膏者，忌再与
重坠之药并用，恐其寒凉侵下焦也，并不可与开破之药同用，因开破之药力原下行也。乃今因肝气胆火相并
上冲，更激动冲气挟胃气上冲，且更有外感之热助之上冲，因致脏腑之气化有升无降，是以饮
食与药至胃中皆不能存留，此但恃石膏之寒凉重坠原不能胜任，故特用赭石之最有压力者以辅之。此
所以旋转脏腑中之气化，而使之归于常也。设非遇此等证脉，则石膏原不可与赭石并用也。
天津的刘某某，三十二岁，在夏末得了温热病，同时伴有呕吐，无法进食。
病因 因为在学校宿舍住宿，有一天学校没人，他的被褥被人偷走了，追赶不及，于是用力奔跑，全身出汗，乘凉休息后，就得了这个病。
证候 心中烦闷发热，周身时常出汗，从第二天开始，呕吐不能进食。到现在已经四天了，多次服药也都吐出来了，即使口渴时喝水也常常吐出。舌苔白而厚腻，大便四天没有排出。脉象左部弦硬，右部弦长有力，一息五至（每分钟呼吸五次以上）。
诊断 其脉象左部弦硬，是肝胆之火炽盛的表现。右部弦长，是冲气挟带胃气上冲的表现。脉象弦长且兼有力量，说明外感的热邪已经传入阳明腑。此证是因为被盗事件激怒了肝气，导致肝火上冲，并激动了冲气挟带胃气一同上冲，而外感的热邪又在胃中炽盛以助纣为虐，所以出现烦热、出汗、不能进食以及吐药、吐水的症状。对此应当投用清热镇逆的方剂。
处方 生石膏（二两细末） 生赭石（六钱细末） 镜面朱砂（五钱细末）
混合均匀分成五包，先送服一包，过两个小时再送服一包，病愈即停止服用，不必服完所有药剂。方子使用散剂而不使用汤剂，是因为止呕吐的药丸和散剂优于汤剂。
效果 服用到两包时，呕吐已痊愈，心中仍然觉得烦热。服用到四包时，烦热完全痊愈，大便也通畅排出了。
帮助 石膏属于石质药物，本性沉重且寒凉，所以在白虎汤中以石膏为主药，并用甘草来缓和它，用粳米来调和它，希望它在服用后留恋于胃中，不至于迅速下行。因此，使用石膏时，忌讳再与重坠的药物并用，恐怕其寒凉之性损伤下焦；也不可与开破（行气破滞）的药物同用，因为开破药物的作用力原本就是下行的。然而现在因为肝气和胆火相并上冲，更激动了冲气挟带胃气上冲，且更有外感的热邪助其上冲，导致脏腑的气化功能只有升而没有降，所以饮食和药物进入胃中都不能存留。这种情况仅依靠石膏的寒凉重坠原本不能胜任，所以特别使用最有压力的赭石来辅助它。这就是为了旋转脏腑中的气化功能，使其恢复正常。如果不是遇到这种脉象的病症，那么石膏原本是不可与赭石并用的。
Liu XX, aged 32, from Tianjin, contracted a warm-heat disease (Wenbing) in late summer, accompanied by vomiting and an inability to retain food or drink.
Etiology: He was lodging at a school. One day, as the school was empty, his bedding was stolen. After failing to catch the thief, he exerted himself running, sweating profusely throughout his body. Subsequently, while resting and cooling off, he fell ill with this condition.
Symptoms: He experienced mental restlessness and heat sensation, with frequent sweating all over his body. Starting from the second day, he suffered from vomiting and could not retain food. It had been four days since onset; multiple doses of medicine taken previously were all vomited up, and even water drunk when thirsty was frequently vomited. The tongue coating was white and thick/greasy. Bowel movements had not occurred for four days. The pulse was wiry and hard on the left side, and wiry, long, and forceful on the right side, with five breaths per pulse beat (indicating a rapid pulse).
Diagnosis: The wiry and hard pulse on the left indicates blazing fire of the Liver and Gallbladder. The wiry and long pulse on the right indicates Chong Qi (Penetrating Vessel Qi) carrying Stomach Qi upward. The wiry, long, and forceful nature of the pulse indicates that the external pathogenic heat has entered the Yangming Fu organs. This case arose because the theft incident angered the Liver Qi, causing Liver Fire to rush upward, which further agitated the Chong Qi to carry Stomach Qi upward. Meanwhile, the external pathogenic heat blazed in the Stomach, exacerbating the condition. Consequently, there was mental restlessness, sweating, inability to eat, and vomiting of both medicine and water. Treatment should involve administering a formula to clear heat and subdue rebellion (descending adverse Qi).
Prescription: Raw Gypsum Powder (Shi Gao), 2 liang; Raw Hematite Powder (Zhe Shi), 6 qian; Mirror-polished Cinnabar Powder (Zhu Sha), 5 qian. Mix evenly and divide into five packets. Administer one packet first, then another two hours later. Stop administration once the illness resolves; it is not necessary to consume the entire course. The prescription uses powder rather than decoction because powders and pills are superior to decoctions for stopping vomiting.
Outcome: After taking two packets, vomiting ceased, though mental restlessness and heat persisted. After taking four packets, the restlessness and heat completely resolved, and bowel movements became regular.
Explanation: Gypsum is a mineral substance, inherently heavy and cold. In Bai Hu Tang (White Tiger Decoction), Gypsum is the chief herb, moderated by Licorice Root (Gan Cao) and harmonized with Rice (Jing Mi), intending for it to linger in the Stomach after ingestion rather than descending rapidly. Therefore, when using Gypsum, it is contraindicated to combine it with other heavy-sinking herbs, lest its cold nature damage the Lower Jiao; nor should it be combined with dispersing and breaking herbs (Kai Po Zhi Yao), as their action is inherently downward. However, in this case, due to the concurrent upward rushing of Liver Qi and Gallbladder Fire, further agitating the Chong Qi to carry Stomach Qi upward, and aided by external pathogenic heat, the Qi transformation of the Zang-Fu organs became characterized by ascending without descending. Thus, food and medicine entering the Stomach could not be retained. Relying solely on the cold and heavy properties of Gypsum would be insufficient. Hence, Hematite (Zhe Shi), possessing the strongest descending pressure, is specifically used to assist Gypsum. This serves to rotate the Qi transformation within the Zang-Fu organs, restoring normal function. Had the pulse not presented in this specific manner, Gypsum would originally have been contraindicated for simultaneous use with Hematite.
