《金匮》云∶五劳虚极羸瘦，（经云∶五劳所劳伤，久视伤血，久卧伤气，久坐伤肉，
久立
瘦，大肉欲脱也。）腹满（脾不健运也。）不能饮食，（胃不容纳也。）食伤、饮伤、忧伤、房
劳伤、饥伤、劳伤、经络荣卫气血伤，（其受病之原不同，皆可以渐而至极。）内有干血，（
诸伤脏腑，则真气不能统血于周身，营血痹着，而不行于经络，是以瘀积不散而内有干血也
。）肌肤甲错，（甲错者，如鳞也。）两目黑黯，（肝主血，主目，干血之气，内乘于肝，则上
熏于目，而黑黯也。）缓中补虚，此丸主之。（瘀血得去，饮食自进，则气血复，故为缓中补
虚。）
大黄（酒蒸，三两） 虫（三两） 水蛭（炒枯） 虻虫（去足、翅，炒） 蛴螬（炙焦）
干漆（
破血去瘀之品，君以大黄听令于将军矣） 黄芩（清热，以瘀久必生热也。酒炒，一两） 杏
仁（利气，以气滞则不行也。去皮尖，三两） 生地（四两） 芍药（收养阴血，酒炒，二两）
甘草（调和诸药，一两）
十三味为末，蜜丸小豆大，酒送五丸，每日三服。
此方破血行瘀，乃世俗所称干血劳之良治也。内有干血瘀积之久，牢不可拔。新生血
不能周
血，峻药缓图，陆续渐除，俾瘀积去，而虚劳庶可复，死里求生之方也。嘉言云∶有劳之之
极，血滞不行，惟就干涸，皮鲜滑泽，面无荣润。于是气之所过，血不为动，徒蒸血热，或
日晡，或子午，始必干蒸，候蒸散，微汗而热解，热蒸不已，不死何待？甚有热久则蒸，其
所瘀之血，化而为虫，遂成传尸瘵症。又云∶童子脏腑脆嫩，才有寒热积滞，易于结癖成疳
，待其血痹不行，气蒸发热，即女子血干经闭，发热不止，劳瘵之候更多，待其势成，纵有
良法，治之无及。倘能服膺仲景几先之哲，于男子童子女子瘵病，将成未成之候，胃气尚可
胜药，急宜导其血，同人参以行之。如琼玉膏中加桃仁泥、大黄末之属，或用此丸，以琼玉
膏润补之药送之。行瘀退热，全生保命，所关甚大，第率常者，弗能用耳！愚按∶此方乃攻
击之剂，因干血而设，非虚劳常用之方，若见之不真而误投，反速之毙矣。
《金匮要略》中说：五劳（久视伤血、久卧伤气、久坐伤肉、久立伤骨、久行伤筋）导致极度虚弱消瘦，（经文说：五劳所致的劳伤，长时间用眼耗伤血液，长时间卧床耗伤气，长时间坐着耗伤肌肉，长时间站立耗伤骨骼，长时间行走耗伤筋脉。）身体极度消瘦，大肌肉即将脱失。（腹满胀，因脾脏不能正常运化水谷精微所致。）无法进食，（胃腑失去容纳受纳的功能。）饮食不节损伤、饮酒过度损伤、忧思过度损伤、房事劳累损伤、饥饿损伤、劳力过度损伤，导致经络、营气、卫气及气血受损，（虽然致病根源不同，但都可以逐渐发展到极点。）体内有干涸的瘀血，（各种损伤脏腑后，真气不能统摄血液运行于全身，营血痹阻停滞，不能在经络中运行，因此瘀积不散而在体内形成干血。）皮肤粗糙如鳞甲交错，（甲错，指皮肤像鱼鳞一样交错。）两眼周围黑黯，（肝主藏血且开窍于目，干血之气内侵肝脏，向上熏蒸于眼部，导致眼周黑黯。）此方具有缓中（缓和补益中焦脾胃）补虚的功效，用大黄䗪虫丸主治。（瘀血去除后，饮食自然增进，气血得以恢复，所以称为缓中补虚。）
大黄（酒蒸，三两） 䗪虫（三两） 水蛭（炒至枯焦） 虻虫（去掉足和翅膀，炒制） 蛴螬（炙烤至焦黄）
干漆（
破血去瘀的药物，以大黄为君药，如同听令于将军一般） 黄芩（清热，因为瘀血日久必然生热。酒炒，一两） 杏仁（利气，因为气滞则血不行。去皮尖，三两） 生地（四两） 芍药（收养阴血，酒炒，二两）
甘草（调和诸药，一两）
将以上十三味药研成细末，用蜂蜜制成如小豆大小的丸剂，每次服用五丸，用酒送服，每日三次。
此方具有破血行瘀的功效，是世俗所称“干血劳”的良好治疗方法。体内干血瘀积时间长久，牢固难以拔除。新产生的血液不能周身运行，故用峻猛药物缓慢图治，陆续逐渐消除，使瘀积去除，而虚劳症状或许可以恢复，这是一首死里求生的方剂。嘉言（喻昌）说：有劳损至极的情况，血液滞涩不行，最终变得干涸，皮肤鲜滑润泽，面色没有荣华滋润。于是气经过的地方，血液不再流动，徒然蒸腾血液产生热邪，有时在下午申时，有时在子午时，开始必定是干蒸发热，等到蒸散后，微微出汗而热解，如果热蒸不停止，不死还等什么？甚至有热久则蒸，其所瘀积的血液，化为虫，遂成为传尸瘵症（肺结核等慢性消耗性传染病）。又说：童子脏腑脆嫩，刚出现寒热积滞，容易结癖成疳（小儿疳积），等到血液痹阻不行，气蒸发热，就像女子血枯经闭，发热不止，这是劳瘵的征候更多见，等到病势形成，即使有良法，治疗也来不及了。如果能信奉仲景先见之明，对于男子童子女子的瘵病，将成未成的阶段，胃气还可以胜任药力，急宜引导其血液，同人参一起推动运行。如在琼玉膏中加入桃仁泥、大黄末之类的药物，或者使用此丸，用琼玉膏这种润补的药物送服。行瘀退热，保全生命，关系非常大，只是通常的人，不能做到罢了！我按语认为：此方是攻伐的药剂，针对干血而设，不是虚劳常用的方剂，如果看不真切而误投，反而加速死亡。
According to the *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet): "Five labors" (Wu Lao, referring to injuries caused by prolonged visual strain damaging blood, prolonged lying down damaging Qi, prolonged sitting damaging flesh, prolonged standing damaging bones, and prolonged walking damaging sinews) lead to extreme deficiency and emaciation. The classic text states: "The injuries caused by the five labors..." Emaciation is severe, with large muscles about to atrophy. Abdominal fullness is due to the Spleen's failure in transportation and transformation. Inability to eat is due to the Stomach's loss of reception and containment. Injuries from improper diet, excessive drinking, excessive worry, sexual exhaustion, hunger, and physical overwork damage the meridians, Ying-Qi, Wei-Qi, and Qi-Blood. Although the origins of disease differ, they can all gradually progress to an extreme state. There is dry blood inside the body. Various injuries to the Zang-Fu organs prevent True Qi from governing the circulation of blood throughout the body; Ying-Blood becomes bi-stagnant and fails to circulate in the meridians, resulting in accumulated stasis that does not disperse, forming dry blood internally. The skin is rough like fish scales (jia cuo), and the area around both eyes is dark. The Liver stores blood and opens into the eyes; the qi of dry blood invades the Liver internally and steams upward to the eyes, causing darkness. This pill treats this condition by "soothing the center and tonifying deficiency." Once the blood stasis is removed, appetite naturally returns, and Qi-Blood recovers, hence it is called "soothing the center and tonifying deficiency."
Da Huang (Rhizoma Rhei Palmati, steamed with wine, 3 liang), E Chong (Whole Ground Beetle, 3 liang), Shui Zhi (Leech, stir-fried until crisp), Meng Chong (Male Blowfly, feet and wings removed, stir-fried), Qi Qiao (Larva of Cockchafer, roasted until scorched), Gan Xi (Resina Semecarpis Anacardii, [Note: Text implies description here]), Huang Qin (Radix Scutellariae Baicalensis, clears heat because long-standing stasis generates heat; stir-fried with wine, 1 liang), Xing Ren (Seed of Apricot, promotes Qi movement because Qi stagnation impedes flow; skin and tips removed, 3 liang), Sheng Di Huang (Radix Rehmanniae Preparata, 4 liang), Shao Yao (Radix Paeoniae Alba, nourishes and collects Yin-Blood; stir-fried with wine, 2 liang), Gan Cao (Radix Glycyrrhizae Uralensis, harmonizes the various herbs, 1 liang).
Grind the above thirteen ingredients into powder, make pills using honey, sized like small beans. Take 5 pills each time, delivered with wine, three times daily.
This formula breaks blood and moves stasis; it is an excellent treatment for what is commonly known as "Dry Blood Labor" (Gan Xue Lao). The internal accumulation of dry blood stasis has persisted for a long time and is firmly entrenched, difficult to eradicate. New blood cannot circulate throughout the body. Therefore, harsh medicines are used for slow results, gradually eliminating the stasis successively. Once the stasis is removed, the consumptive disorder may recover; this is a prescription for survival from death. Jiayan (Yu Chang) stated: In cases of extreme labor injury, blood stagnates and fails to move, eventually becoming dry. The skin may appear fresh and smooth, and the face lacks luster. Wherever Qi passes, blood no longer moves, merely steaming the blood to generate heat. This may occur in the afternoon (Shi hour) or at Zi/Wu hours. Initially, there is dry steaming fever; after the steaming dissipates, slight sweating resolves the heat. If the steaming heat continues incessantly, how can one avoid death? Furthermore, prolonged heat steaming can transform the stagnant blood into parasites, leading to "Chuan Shi Zhai" (Infectious Consumption Disease/Tuberculosis). He also said: Children have fragile and tender Zang-Fu organs. When cold-heat and stagnation first appear, it is easy to form masses and become pediatric malnutrition (Gan syndrome). By the time blood bi-stagnation occurs and Qi evaporation causes fever, similar to women with dried blood and amenorrhea with continuous fever, these are signs of labor consumption. Once the condition develops, even with good methods, treatment will be too late. If one could heed Zhongjing's foresight, for children and adults with consumption diseases in the pre-manifest stage, where Stomach Qi can still withstand medication, one should urgently guide the blood, administering it together with Ren Shen (Radix Ginseng) to promote its movement. For example, add Tao Ren (Semen Persicae) paste and Da Huang powder to Qiong Yu Gao (Jade Essence Paste), or use this pill, delivering it with the nourishing Qiong Yu Gao. Moving stasis and reducing fever, preserving life, is of great importance; however, ordinary people are unable to do so. My commentary: This formula is an attacking agent, designed specifically for dry blood, not a common formula for general consumption disorders. If the diagnosis is not clear and it is mistakenly administered, it will instead accelerate death.
