若因痛甚，或因克伐而伤胃者，用四君、当归、半夏、生姜。或因忿怒而肝伤者，用
小柴胡汤加山栀、茯苓。若因痰火盛，用二陈、姜炒黄连、山栀。若因胃气虚，用补中
益气汤生姜、半夏。若出血过多，或因溃后，用六君子汤加当归。有一患者，痛甚发热，
呕吐少食，胸膈痞满，用行气破血之剂益甚，口干作渴，大便不调，患处色黯。薛曰∶此
痛伤胃气所致，遂以四君、当归、炒芩、软柴、藿香，二剂诸症渐愈；又用大补之剂，溃
之而瘳。 有一患者，发热 痛，服寒凉药，更加口干作渴，肚腹亦痛，自以为瘀血，欲
下之。薛按其肚腹不痛，脉微细而迟，饮食恶寒，此凉药伤胃而然也，急用六君加芍药、
当归、炮附子各一钱，服之前症益甚，反加谵语，面赤。薛意其药力未至耳！前药再加
附子五分，服之即睡，觉来诸病顿退而安。一膏粱之人，跌腿青肿作痛，服辛热之药，反
发热作喘，患处益痛，口干唇揭。薛曰∶膏粱之人，内多积热，更服辛热之剂，益其胃
火而使然也，频饮童便，以清胃散加山栀、黄芩、甘草，治之顿止，患处以葱熨之，肿即
消散。 一妇人伤指，手背俱肿，微呕少食，彼以为毒瓦斯内攻，诊其脉沉细，此痛伤胃气
所致也。遂刺出脓碗许，先以六君、藿香，当归而食进。继以八珍、黄 、白芷、桔梗，月
余而疮愈。
如果是因为疼痛剧烈，或者因为过度使用攻伐药物而损伤了胃气，就使用四君子汤、当归、半夏、生姜。如果是由于愤怒导致肝受损，就使用小柴胡汤加山栀、茯苓。如果是因为痰火旺盛，就使用二陈汤、姜炒黄连、山栀。如果是因为胃气虚弱，就使用补中益气汤加生姜、半夏。如果是因为出血过多，或者在溃疡之后，就使用六君子汤加当归。
有一位患者，疼痛剧烈且发热，呕吐且进食少，胸膈部痞塞胀满，使用了行气破血的药剂后症状反而加重，出现口干想喝水，大便不调，患处颜色暗紫。薛己说：这是疼痛损伤了胃气所致，于是用四君子汤、当归、炒黄芩、软柴胡、藿香，服用两剂后各种症状逐渐痊愈；接着又用了大补的药剂，促使脓液排出后病愈。
有一位患者，发热且疼痛，服用了寒凉药物后，更加口干想喝水，肚子和腹部也痛，自认为是瘀血，想要用泻下法治疗。薛己按压他的肚腹并不痛，脉象微细而迟，饮食减少且怕冷，这是寒凉药物损伤了胃气造成的，急忙使用六君子汤加芍药、当归、炮附子各一钱，服用之前症加剧，反而加上胡言乱语，面色发红。薛己推测是药力还没到达病所！在前方的基础上再加附子五分，服用后即入睡，醒来后各种病症顿时消退而安宁。
一位平时饮食肥甘厚味的人，腿部跌打损伤青肿疼痛，服用了辛热性质的药物，反而发热气喘，患处更加疼痛，口干唇皮揭裂。薛己说：平时吃得好的人，体内多有积热，再服用辛热的药剂，助长了胃火从而造成这种情况，频繁饮用童便（童子尿），并用清胃散加山栀、黄芩、甘草来治疗，症状立刻停止，患处用葱白熨烫，肿胀随即消散。
一位妇人手指受伤，手背都肿了，轻微呕吐且进食少，她以为是毒气内攻，诊察她的脉象沉细，这是疼痛损伤了胃气所致。于是刺出约一碗脓，先用六君子汤、藿香、当归，之后食欲恢复。接着用八珍汤加黄芪、白芷、桔梗，一个多月后疮口愈合。
If the condition arises from severe pain or from excessive use of purgative/draining drugs that damage Stomach Qi, employ Sijunzi Tang (Four Gentlemen Decoction), Danggui (Radix Angelicae Sinensis), Banxia (Rhizoma Pinelliae), and Shengjiang (Rhizoma Zingiberis Recens). If it results from anger causing Liver injury, employ Xiaochaihu Tang (Minor Bupleurum Decoction) with Zhizi (Fructus Gardeniae) and Fuling (Poria). If it is due to abundant Phlegm-Fire, employ Erchen Tang (Two Aged Substances Decoction) with Huanglian (Rhizoma Coptidis) stir-fried with ginger and Zhizi (Fructus Gardeniae). If it stems from deficiency of Stomach Qi, employ Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Shengjiang (Rhizoma Zingiberis Recens) and Banxia (Rhizoma Pinelliae). If it follows excessive bleeding or occurs after ulceration, employ Liujunzi Tang (Six Gentlemen Decoction) with Danggui (Radix Angelicae Sinensis).
One patient suffered from severe pain and fever, vomiting with poor appetite, and fullness/stuffiness in the chest and diaphragm. After administering formulas for moving Qi and breaking blood stasis, symptoms worsened; dry mouth with thirst, irregular bowel movements, and a dark discoloration at the lesion site appeared. Xue Ji stated: This is caused by pain damaging Stomach Qi. He subsequently prescribed Sijunzi Tang (Four Gentlemen Decoction), Danggui (Radix Angelicae Sinensis), Chao Qin (Stir-fried Radix Scutellariae), Ruan Chaihu (Soft Bupleuri Radix), and Huoxiang (Agastaches Herba). After two doses, various symptoms gradually improved; subsequently, a strongly tonifying formula was used to promote suppuration, leading to recovery.
Another patient presented with fever and pain. After taking cold-natured drugs, dry mouth with thirst intensified, accompanied by abdominal pain. The patient suspected blood stasis and desired purgation. Upon palpation of the abdomen, there was no tenderness; the pulse was faint, fine, and slow, with reduced intake of food and aversion to cold. This indicated that cold drugs had damaged Stomach Qi. Urgently, Liujunzi Tang (Six Gentlemen Decoction) was administered with Shaoyao (Radix Paeoniae Alba), Danggui (Radix Angelicae Sinensis), and Paofuzi (Prepared Radix Aconiti Lateralis Preparata), each one qian. Before this dose took effect, previous symptoms worsened, accompanied by delirious speech and flushed face. Xue Ji surmised that the medicinal force had not yet reached the disease site. An additional five fen of Fuzi (Radix Aconiti Lateralis Preparata) was added to the prescription. After ingestion, the patient fell asleep; upon waking, all ailments suddenly receded, and peace was restored.
A person accustomed to rich and greasy foods suffered a leg contusion with cyanosis, swelling, and pain. After taking acrid-warm drugs, fever and wheezing developed, the lesion became more painful, and dry mouth with peeling lips occurred. Xue Ji said: Individuals consuming rich diets often have accumulated internal heat. Administering acrid-warm agents further exacerbates Stomach Fire, causing these symptoms. Frequent drinking of Tongbian (Urine of an uncircumcised boy) was recommended to clear the Stomach, along with Qingwei San (Clear the Stomach Powder) plus Zhizi (Fructus Gardeniae), Huangqin (Radix Scutellariae), and Gancao (Radix Glycyrrhizae Uralensis). Treatment brought immediate cessation of symptoms. The lesion was treated with warming moxibustion using Congbai (White Part of Allium Fistulosum), resulting in rapid resolution of swelling.
A woman injured her finger, resulting in swelling of the entire dorsum of the hand, slight vomiting, and poor appetite. She believed it was due to toxic qi attacking internally. Palpation revealed a deep and fine pulse. Xue Ji diagnosed this as pain damaging Stomach Qi. Pus amounting to approximately one bowl was drained. Initially, Liujunzi Tang (Six Gentlemen Decoction), Huoxiang (Agastaches Herba), and Danggui (Radix Angelicae Sinensis) were given, after which appetite returned. Subsequently, Bazhen Tang (Eight Treasures Decoction) was combined with Huangqi (Radix Astragali Membranacei), Baizhi (Radix Angelicae Dahuricae), and Jiegeng (Radix Platycodonis Grandiflori). Over a month, the sore healed.
