薛立斋治一童子，腋下患痈，久不敛，脓清，脉大，倦怠懒食，少寐自汗，口干，以内补黄 汤
及豆豉饼灸之，两月而愈。凡疮脓溃而清，或疮口不合，或聚肿不赤，肌肉寒冷，自汗色脱者，皆气
血俱虚也，非补不可。
一男子腋下患毒，咳逆不食，肠鸣切痛，四肢厥冷，脉细，以托里温中汤，二剂顿愈。更以香砂
六君子汤、三神丸，而饮食顿进。以十全大补汤，二十剂而敛。
里中有周七者，少年，曾患毒左腋下，得一异方，用糯米 饭，乘热入盐块，夹葱管少许，捣极
烂如膏，贴患处辄消。至中年，腰间忽生一毒，热如火，板硬痛不可忍，伛偻 ，自分必死，屡药
不效。急思前方，如法贴之。未几，大便去粪如宿垢，甚多，硬者渐软，数日而起。
薛立斋心法，治河南张承祖，年逾二十，腋下患毒，十余日肿硬不溃，脉弱时呕。谓肿硬不溃，
脉弱，乃阳气虚；呕吐少食，乃胃气弱。先以六君子汤加藿香、砂仁治之。彼谓肿疡时呕，当作毒瓦斯
攻心治之；溃疡时呕，当作阴虚补之。曰∶此丹溪大概之言也，即诸痛痒疮，皆属心火之意。假如赤
肿痛甚，烦躁脉实而呕，为有余，法当下；不肿硬，不痛不溃，脉弱而呕，为不足，法当补之。亦有
痛伤胃气，或感寒邪秽气而作呕者，虽肿疡，尤当助胃壮气。彼执不用，信用攻伐之药，病愈甚。复
请诊，其脉微细，而发热。谓热而脉静，脱血脉实，汗后烦躁者，皆难治。后果然。夫肿疡毒瓦斯内侵
作呕，十有一二，溃疡湿气内侵作呕，十有八九，岂可混为一途？
朱文鼎母，因忿郁，腋下结一核，二十余年。因怒，加肿痛，完谷不化，饮食少思。东垣云∶泻
利不止，饮食不入，此肠胃虚也。遂以六君子汤加砂仁、肉桂、干姜、肉豆蔻，泻虽止而脓清，疮口
不合，气血虚也。以十全大补汤，月余而愈。
一男子年逾五十，腋下患毒，疮口不合，右关脉数而渴，此胃火所致，用竹叶黄 汤遂止。再用
补气药而愈。尝治午后发渴，或发热，用地骨皮散亦效。
薛立斋治疗一名童子，腋下患痈疽，长期不愈合，脓液清稀，脉象大，精神疲倦，食欲不振，睡眠少且自汗，口干，使用内补黄芪汤以及豆豉饼灸法治疗，两个月后痊愈。凡是疮疡脓液溃破后清稀，或者疮口不合拢，或者肿胀聚集但不发红，肌肉寒冷，自汗面色苍白脱色的，都是气血俱虚的表现，必须采用补益疗法。
另一名男子腋下患毒疮，咳嗽气逆，不能进食，肠鸣剧烈疼痛，四肢厥冷，脉象细，使用托里温中汤，两剂药后立刻痊愈。随后改用香砂六君子汤、三神丸，饮食立刻增进。再用十全大补汤，二十剂后疮口收敛。
乡里有个叫周七的人，年轻时曾在左腋下患毒疮，得到一个异方，用糯米饭，趁热放入盐块，夹少许葱管，捣烂如膏状，贴在患处随即消散。到了中年，腰间忽然生一毒疮，热如火烧，板硬疼痛难忍，弯腰曲背，自己断定必死无疑，多次用药无效。急忙想起前面的方子，照法贴敷。不久，大便排出像宿垢一样的粪便，量很多，硬的逐渐变软，几天后就康复了。
薛立斋运用心法治疗河南人张承祖，年龄超过二十岁，腋下患毒疮，十多天肿胀坚硬且不溃破，脉弱时常呕吐。薛立斋说：肿胀坚硬不溃破，脉弱，这是阳气虚；呕吐少吃不下，这是胃气弱。先用六君子汤加藿香、砂仁治疗。患者认为肿疡期呕吐，应当当作毒瓦斯攻心来治；溃疡期呕吐，应当当作阴虚来补。薛立斋说：这是朱丹溪的大概言论，即“诸痛痒疮，皆属于心火”的意思。假如红肿疼痛严重，烦躁脉实而呕吐，属于有余（实证），治法应当攻下；如果不肿硬，不痛不溃破，脉弱而呕吐，属于不足（虚证），治法应当补益。也有因疼痛损伤胃气，或感受寒邪秽气而作呕的，即使是肿疡期，尤其应当助胃壮气。患者固执己见不用此法，信用攻伐的药物，病情更加严重。再次请诊，其脉微细，并且发热。薛立斋说：发热而脉静，脱血而脉实，发汗后烦躁的，都难治。后果然如此。凡是在肿疡期毒瓦斯内侵导致呕吐的，十有一二；在溃疡期湿气内侵导致呕吐的，十有八九，怎么能混为一谈呢？
朱文鼎的母亲，因为愤怒抑郁，腋下结成一核，长达二十多年。因为发怒，加上肿痛，完谷不化，饮食减少不想吃。李东垣说：泻利不止，饮食不入，这是肠胃虚。于是用六君子汤加砂仁、肉桂、干姜、肉豆蔻，腹泻虽然止住了但脓液清稀，疮口不合，这是气血虚。用十全大补汤，一个多月后痊愈。
一名五十多岁的男子，腋下患毒疮，疮口不合，右关脉数且口渴，这是胃火所致，用竹叶黄芪汤随即停止。再用补气药而痊愈。曾经治疗午后发渴，或发热，用地骨皮散也有效。
Dr. Xue Lizhai treated a young boy who suffered from a carbuncle in the axilla that had failed to heal for a long time, with thin pus, a large pulse, fatigue, poor appetite, insomnia with spontaneous sweating, and dry mouth. He prescribed Neibu Huangqi Tang (Internal Nourishing Decoction of Astragalus) and moxibustion using fermented soybean cakes. The condition healed after two months. Generally, when pus from a sore is thin after ulceration, or the wound fails to close, or swelling gathers without redness, or muscles feel cold with spontaneous sweating and pallor, it indicates deficiency of both Qi and Blood, which necessitates tonification.
A man suffered from a toxic sore in the axilla, accompanied by coughing and counterflow qi, inability to eat, loud borborygmus with severe pain, cold limbs, and a fine pulse. He was treated with Tuoli Wenzhong Tang (Support Interior and Warm Middle Decoction), recovering abruptly after two doses. Subsequently, Xiangsha Liujunzi Tang (Aucklandia and Amomum Six Gentlemen Decoction) and Shenshen Wan (Three Divine Pills) were used, leading to an immediate improvement in diet. Finally, Shiquan Dabu Tang (Perfect Ten Tonifying Decoction) was administered for twenty doses until the wound closed.
In the neighborhood, there was a young man named Zhou Qi who once suffered from a toxic sore in his left axilla. He obtained an unusual prescription: glutinous rice mixed with salt blocks while hot, along with a small amount of scallion tubes, pounded into a paste-like consistency and applied to the affected area, which caused the swelling to dissipate immediately. In middle age, he suddenly developed a toxic sore on his waist, burning like fire, hard and unbearably painful, forcing him to bend over. Believing death was inevitable and having tried many medicines without effect, he urgently recalled the previous formula and applied it as directed. Soon after, he passed a large amount of stool resembling old fecal matter; the hard stools gradually softened, and he recovered within a few days.
Applying his clinical insights, Dr. Xue Lizhai treated Zhang Chengzu from Henan, who was over twenty years old and had a toxic sore in the axilla that remained swollen and hard without ulcerating for more than ten days, accompanied by a weak pulse and occasional vomiting. Dr. Xue stated: Swelling and hardness without ulceration and a weak pulse indicate deficiency of Yang Qi; vomiting and poor intake indicate weak Stomach Qi. He first prescribed Liujunzi Tang (Six Gentlemen Decoction) with Huoxiang (Patchouli Herb) and Sharen (Amomum Fruit). The patient argued that vomiting during the abscess stage should be treated as toxin attacking the Heart, and vomiting during the ulcer stage as Yin deficiency requiring supplementation. Dr. Xue replied: This is a generalization from Zhu Danxi, based on the principle that "all pain, itching, and sores belong to Heart Fire." If there is severe redness, swelling, and pain, with restlessness, a full pulse, and vomiting, it is excess, and purgation is indicated. If there is no swelling or hardness, no pain or ulceration, but a weak pulse and vomiting, it is deficiency, and tonification is indicated. There are also cases where pain damages Stomach Qi, or exposure to cold pathogenic factors and foul air causes vomiting; even in the abscess stage, strengthening the Stomach and boosting Qi is particularly important. The patient persisted in his view, refused this treatment, and relied on draining and attacking herbs, causing the disease to worsen. Upon re-examination, his pulse was minute and fine, and he had a fever. Dr. Xue said: Fever with a quiet pulse, bleeding with a full pulse, and restlessness after sweating are all difficult to treat. This proved true later. Cases of vomiting due to internal invasion of toxins during the abscess stage account for one or two out of ten; cases of vomiting due to internal invasion of dampness during the ulcer stage account for eight or nine out of ten. How can they be confused?
Madam Zhu Wendding, due to anger and depression, developed a nodule in her axilla that persisted for over twenty years. Due to anger, she experienced increased swelling and pain, undigested food in stool, and loss of appetite. Li Dongyuan stated: Unstopping diarrhea and inability to eat indicate deficiency of the Intestines and Stomach. Thus, Liujunzi Tang was prescribed with Sharen, Rougui (Cinnamon Bark), Ganjiang (Dried Ginger), and Roudoukou (Nutmeg). Although the diarrhea stopped, the pus remained thin and the wound did not close, indicating deficiency of Qi and Blood. She was treated with Shiquan Dabu Tang and healed after more than a month.
A man over fifty years old suffered from a toxic sore in the axilla with a non-healing wound, a rapid pulse at the right Guan position, and thirst. This was caused by Stomach Fire. Zhuye Huangqi Tang (Bamboo Leaf and Astragalus Decoction) stopped the symptoms. Subsequent use of Qi-tonifying herbs led to recovery. He once treated thirst occurring in the afternoon or fever using Gudupi San (Morus Root Bark Powder), which was also effective.
