若出血过多，或溃脓之后，脉洪大而虚，重按全无，此阴虚发热也，用当归补血汤。脉
沉微，按之软弱，此阴盛发躁也，用四君姜附。若发热烦躁，肉润筋惕，亡血也，用圣
愈汤。如汗不止，血脱也，用独参汤。其血脱脉实，汗后脉躁者，难治；细小者，易治。
《外台秘要》云∶阴盛发躁，欲坐井中，用附子四逆汤加葱白。王太仆先生云∶凡热来复
去，昼见夜伏，夜见昼伏，不时而动者，名曰无火，此无根之虚火也。 杨进士，伤手
指， 痛发热，服寒凉之药，致饮食顿减，患处不溃。薛用托里养血之药，食进疮溃。后
因劳，每日晡发热，此阴虚而内热也，以四物，软柴胡、地骨皮乃退，更用养血气之药
而疮敛。 一男子坠马，腹有瘀血，服药下之，致发热盗汗自汗，脉浮涩。薛以为重剂，
过伤气血所致，投以十全大补汤益甚，时或谵语，此药力未及而然也。以前药加炮附子
五分，服之即睡，觉来顿安，再剂而痊。举人余时正，金疮 痛，出血不止，恶寒发
热，用败毒等药愈甚，此亡血过多，气无所附而然耳。遂以四物、黄柏、知母、软柴胡、
玄参、五味、麦门，治之即愈。 一女子年十七，闪右臂微肿作痛，寅申时发热。薛决
其胆经血虚火盛，经水果先期而至。先以四物合小柴胡汤，四剂热退；更以加味四物汤
加香附、地骨皮。山栀（各五分），芩、连、炙草（各三分），二十余剂，其肿亦消，乃去黄连、山
栀又五十余剂，经水调而元气充矣。
如果失血过多，或者溃烂流脓之后，脉象洪大但按之空虚，重按时完全无力，这是阴虚发热，应当使用当归补血汤。如果脉象沉微，按之软弱无力，这是阴寒内盛导致的烦躁，应当使用四君子汤加干姜、附子。如果出现发热烦躁，肌肉跳动、筋脉抽搐，这是亡血所致，应当使用圣愈汤。如果汗出不止，这是血脱证，应当使用独参汤。如果是血脱而脉象实大，或者发汗后脉象躁动不安的，难以治疗；如果脉象细小柔和的，容易治疗。《外台秘要》中说：阴寒内盛导致烦躁，患者想要坐在井中降温，应当使用附子四逆汤加葱白。王太仆（王冰）先生说：凡是热势来去无常，白天出现晚上潜伏，晚上出现白天潜伏，不时发作的，叫做“无火”，这是无根之虚火。杨进士，手指受伤，疼痛且发热，服用寒凉药物后，导致饮食突然减少，患处不能溃破排脓。薛己使用托里养血的药物，患者食欲恢复，疮疡溃破。后来因为劳累，每天傍晚发热，这是阴虚内热，用四物汤合软柴胡、地骨皮使热退，再服用养血益气的药物，疮口愈合。一个男子从马上摔下，腹部有瘀血，服用攻下药后，导致发热、盗汗和自汗，脉象浮涩。薛己认为是重剂攻下过度损伤气血所致，投以十全大补汤反而加重病情，有时出现胡言乱语，这是药力未到病所而产生的反应。在前方中加入炮附子五分，服用后即能入睡，醒来顿感舒适，再服两剂痊愈。举人余时正，金创疼痛，出血不止，恶寒发热，使用败毒散等药物后病情加重，这是因为失血过多，气无所依附所致。于是用四物汤加黄柏、知母、软柴胡、玄参、五味子、麦门冬治疗，随即痊愈。一个十七岁的女子，扭伤右臂，轻微肿胀疼痛，在寅时和申时发热。薛己判断为胆经血虚火旺，月经果然提前到来。先用四物汤合小柴胡汤，服用四剂后热退；再用加味四物汤加入香附、地骨皮、山栀（各五分）、黄芩、黄连、炙甘草（各三分），服用二十多剂，肿胀消退，然后去掉黄连、山栀，又服用五十多剂，月经调顺，元气充沛。
If excessive blood loss occurs, or after the ulceration and suppuration of a wound, if the pulse is large and forceful on the superficial level but empty upon pressure, and completely weak when pressed deeply, this indicates deficiency-heat due to Yin deficiency; use Danggui Buxue Tang (Dong Quai Tonify Qi and Blood Decoction). If the pulse is deep and faint, soft and weak upon pressure, this indicates restlessness caused by excess Yin cold; use Sijunzi Tang (Four Gentlemen Decoction) with Ganjiang (Dried Ginger) and Fuzi (Prepared Aconite Root). If fever and irritability occur, accompanied by muscle twitching and tendon tremors, this is due to loss of blood; use Shengyu Tang (Sage Renewal Decoction). If sweating does not stop, this is blood collapse; use Dushen Tang (Single Ginseng Decoction). If the pulse is full and forceful in cases of blood collapse, or if the pulse becomes restless after sweating, the condition is difficult to treat; if the pulse is fine and small, it is easy to treat. *Waitai Miyao* (Essential Prescriptions from the Imperial Library) states: Restlessness caused by excess Yin cold, where the patient desires to sit in a well for cooling, should be treated with Fuzi Sini Tang (Aconite Reverse Cold Decoction) plus Congbai (Scallion White). Master Wang Taipu (Wang Bing) stated: Whenever heat comes and goes irregularly, appearing during the day and hiding at night, or appearing at night and hiding during the day, moving unpredictably, this is called "no fire"; this is deficient fire without roots. Scholar Yang suffered an injury to his finger, experiencing pain and fever. After taking cold-natured medicines, his appetite suddenly decreased, and the affected area failed to suppurate. Xue Ji used herbs to support the interior and nourish blood; his appetite returned, and the sore opened. Later, due to overexertion, he experienced daily afternoon fever, indicating internal heat due to Yin deficiency. He used Siwu Tang (Four Substances Decoction) combined with Ruan Chaihu (Soft Bupleurum Root) and Digupi (Cortex Lycii), which resolved the fever; subsequently, using herbs to nourish blood and benefit Qi allowed the sore to heal. A man fell from a horse, resulting in blood stasis in the abdomen. After taking purgative medicines, he developed fever, night sweats, and spontaneous sweating, with a floating and choppy pulse. Xue Ji believed this was caused by heavy purgatives excessively damaging Qi and Blood. He administered Shiquan Dabu Tang (Complete Great Tonifying Decoction), but the condition worsened, and he occasionally spoke deliriously; this was due to the medicinal power not yet reaching the disease site. Adding Paofuzi (Prepared Aconite Root, 5 fen) to the previous prescription allowed him to sleep immediately; upon waking, he felt instantly relieved, and after two more doses, he recovered. Scholar Yu Shizheng suffered a metallic wound with persistent bleeding, aversion to cold, and fever. His condition worsened after using Baidu San (Resolve Toxin Powder); this was because excessive blood loss left Qi without attachment. Thus, he was treated with Siwu Tang (Four Substances Decoction) plus Huangbai (Cortex Phellodendri), Zhimu (Rhizoma Anemarrhenae), Ruan Chaihu (Soft Bupleurum Root), Xuanshen (Radix Scrophulariae), Wuweizi (Fructus Schisandrae), and Maimendong (Radix Ophiopogonis), leading to immediate recovery. A seventeen-year-old woman sprained her right arm, causing slight swelling and pain, with fever occurring at Yin and Shen hours (3–7 AM and 3–7 PM). Xue Ji diagnosed blood deficiency and hyperactive fire in the Gallbladder channel; indeed, her menstruation arrived early. Initially, she took Siwu Tang (Four Substances Decoction) combined with Xiao Chaihu Tang (Minor Bupleurum Decoction) for four doses, resolving the fever. Then, Jiawei Siwu Tang (Modified Four Substances Decoction) was used with Xiangfu (Rhizoma Cyperi), Digupi (Cortex Lycii), Shanzhi (Fructus Gardeniae, each 5 fen), Huangqin (Radix Scutellariae), Huanglian (Rhizoma Coptidis), and Zhigancao (Honey-fried Licorice Root, each 3 fen). After more than twenty doses, the swelling subsided. Huanglian and Shanzhi were then removed, and after another fifty-plus doses, her menstruation became regular, and her Yuan Qi (Original Qi) was replenished.
