人有腹中痛甚，手不可按，而右足屈而不伸，人以为腹中火盛而存食也，谁知
是大肠生痈耳。大凡腹痛而足不能伸者，俱是肠内生痈耳。惟大肠生痈，亦实有其
故，无不成于火，火盛而不散，则郁结而成痈矣。然而火之有余，实本于水之不足，
水衰则火旺，火旺而无制，乃养成其毒而不可解。然则治之法，又何必治火哉，壮
水以治火，则毒瓦斯自消。方用清肠饮∶
金银花（三两） 当归（二两） 地榆（一两） 麦冬（一两） 元参（一两） 生甘草（三钱）
薏仁（五钱） 黄芩（二钱） 水煎服。一剂而痛少止，二剂而足可伸，再二剂而毒尽消矣。
此方纯阴之物，而又是活血解毒之品，虽泻火实滋阴也。所以相济而相成，取
效故神耳。倘不益阴以润肠，而惟攻毒以降火，则大肠先损，又何胜火毒之凌烁哉。
毋怪愈治而愈不能效也。
人有大肠生痈，右足不能伸，腹中痛甚，便出脓血，肛门如刀割，此肠痈已经
溃烂也。能食者生，不能食者死。虽然，不能食之中亦有非因火毒之炽而然者，又
不可因其不能食而弃之也。大凡生此各种痈疮，俱以有胃气为佳，无胃气，毋论阴
毒阳毒多不可救。故治阴疽之病，断以扶胃气为第一法，而少加之败脓祛毒之药，
则正气无伤而火毒又散。今大肠痈破，而致饮食不思，则胃气已尽绝，大危之症也。
不急补胃，惟治痈，必死之道也。方用开胃救亡汤∶
人参（一两） 金银花（二两） 山药（一两） 生甘草（三钱） 薏仁（一两） 元参（一两）
白术（一两） 山羊血（研末，一钱）水煎调服。一剂胃开，二剂脓少，三剂痛止，四剂全愈。
此方全去救胃，而败脓祛毒已在其中。妙在金银花虽治毒而仍滋阴之药，为疮
家夺命之物，军乃至仁至勇之师，又得参、术以补助其力，即散毒尤神。山羊血止
血消渴且善通气，引诸药入痈中解散之，乃乡导之智者也。合而治之，则调合有人，
抚绥有人，攻剿有人，安得不奏功如神乎。自然胃气大开，化精微而辅输于大肠也。
倘胃气未伤，服之尤奏功如向，万勿疑畏不用此方，枉人性命耳。
人有大肠生痈，小腹痛甚，淋漓不已，精神衰少，饮食无味，面色痿黄，四肢
无力，自汗盗汗，夜不能卧，人以为火盛生痈也，谁知水衰不能润肠耳。夫大肠
之能传导者，全藉肾水之灌注。今因醉饱房劳，过伤精力，大泄其精，遂至火动而
水涸，又加生冷并进，以致气血乖违，湿动痰生，肠胃痞塞，运化不通，气血凝滞
而成痈也。然则生痈之先，本是肾水不足，痈溃之后，又复流其水，是因虚而益虚
矣。若作久毒治之，鲜不变为死症，必须大补其肾水，而并补其脾胃之气，则脾胃
化精，生水更易，枯涸之肠一旦得滂沱之润自然淹足，不必治痈而痈已化，气血足
而肌肉生也。方用六味地黄汤加味治之。
熟地（二两） 山药（八钱） 牡丹皮（六钱） 山茱萸（八钱） 茯苓（三钱） 泽泻（一钱）
人参（一两） 黄 （五钱） 麦冬（一两） 水煎。连服数剂，腹痛止而精神健，前症顿愈。
此方六味以补肾水，加人参、麦冬、黄 以补脾胃之土，土旺而肺气自旺。肺
与大肠为表里，且又为肾之母，自然子母相需，表里相顾，故奏功如神也。
有人腹部剧烈疼痛，手不能触碰按压，且右腿弯曲无法伸直。人们以为是腹中火气旺盛且有积食，却不知这是大肠生痈所致。大凡腹痛且腿部无法伸直的情况，都是肠道内部生痈的表现。唯独大肠生痈，也有其形成的原因，没有不是由火邪引起的，火气旺盛而不消散，就会郁结而形成痈肿。然而，火气的有余，实际上根本在于肾水的不足，水液衰少则火气亢盛，火气亢盛而无人制约，便养成毒邪而无法化解。既然如此，治疗的方法，又何必只去治火呢？通过壮补肾水来制约火邪，毒邪自然就会消除。方剂用清肠饮：金银花（三两）、当归（二两）、地榆（一两）、麦冬（一两）、玄参（一两）、生甘草（三钱）、薏苡仁（五钱）、黄芩（二钱），用水煎服。服用一剂后疼痛稍止，服用两剂后腿部可以伸直，再服用两剂后毒邪完全消除。这个方子全是阴柔的药物，又是活血解毒的药材，虽然能泻火，实则是在滋阴。所以相互辅助而成功，取得疗效所以才神奇。如果不益阴以滋润肠道，而只是攻伐毒邪以降火，那么大肠会先受损，又怎能承受住火毒的灼烧呢？难怪越治越无效。
有人大肠生痈，右腿无法伸直，腹部剧痛，排出脓血，肛门像刀割一样疼痛，这是肠痈已经溃烂的表现。能够进食的就能存活，不能进食的就会死亡。虽然如此，在不能进食的情况中，也有并非因为火毒炽盛导致的，又不能因为不能进食就放弃治疗。大凡生出各种痈疮，都以有胃气为最佳，如果没有胃气，不论阴毒还是阳毒都不可救治。所以治疗阴疽这类疾病，断然以扶持胃气为第一法则，稍微加入败脓祛毒的药物，这样正气就不会受伤，而火毒又能散去。如今大肠痈破溃，导致不想饮食，说明胃气已经几乎绝灭，这是非常危险的病症。如果不紧急补益胃气，只去治疗痈肿，必死无疑。方剂用开胃救亡汤：人参（一两）、金银花（二两）、山药（一两）、生甘草（三钱）、薏苡仁（一两）、玄参（一两）、白术（一两）、山羊血（研成粉末，一钱），用水煎煮后调服。服用一剂胃气开，服用两剂脓液减少，服用三剂疼痛停止，服用四剂完全痊愈。这个方子全在于挽救胃气，而败脓祛毒的功效已包含在其中。妙在金银花虽然是治疗毒邪的药物，但仍是滋阴的药材，对于疮疡患者来说是夺命之物（指救命或致命的关键），军队中是至仁至勇的将领，再加上人参、白术来补助它的力量，散发毒邪尤其神奇。山羊血能止血消渴且善于通气，引导诸药进入痈肿中解散它，是如同向导般的智者。合起来治疗，则有调和之人，安抚之人，攻剿之人，怎么能不奏效如神呢？自然胃气大开，化生精微物质并输送到大肠。如果胃气未受损伤，服用此方效果更是迅速，千万不要怀疑畏惧不使用此方，枉人性命。
有人大肠生痈，小腹部剧烈疼痛，淋漓不止，精神衰弱减少，饮食无味，面色萎黄，四肢无力，自汗盗汗，夜晚不能卧床睡眠。人们以为是火气旺盛生了痈，却不知是肾水衰少不能滋润肠道。大肠之所以能传导糟粕，全靠肾水的灌注。如今因为醉酒后饱食及房劳过度，严重损伤精力，大量泄精，导致火动而水干，又加上生冷食物并进，致使气血违逆，湿气变动痰浊生成，肠胃痞塞不通，运化功能受阻，气血凝滞而形成痈肿。然而，生痈之前，本是肾水不足；痈溃之后，又进一步流失水液，这是因虚而更加虚弱。如果当作久毒来治疗，很少有不变成死症的，必须大补肾水，并同时补益脾胃之气，那么脾胃化生精微，生水更容易，干枯的肠道一旦得到充沛的滋润，自然充足，不必专门治疗痈肿，痈肿自然会化解，气血充足而肌肉生长。方剂用六味地黄汤加味治疗。熟地黄（二两）、山药（八钱）、牡丹皮（六钱）、山茱萸（八钱）、茯苓（三钱）、泽泻（一钱）、人参（一两）、黄芪（五钱）、麦冬（一两），用水煎煮。连续服用数剂，腹痛停止且精神健壮，之前的症状顿时痊愈。这个方子用六味药来补肾水，加入人参、麦冬、黄芪来补益脾胃之土，土气旺盛则肺气自然旺盛。肺与大肠互为表里，且肺又是肾之母，自然母子相互需要，表里相互照顾，所以奏效如神。
There is a case where a person suffers from severe abdominal pain, cannot tolerate touch or pressure, and has the right leg flexed and unable to extend. People assume it is due to excessive fire in the abdomen and retained food, but who would know that this is actually an abscess forming in the large intestine (Da Chang). Generally speaking, abdominal pain accompanied by the inability to extend the legs indicates an abscess within the intestines. The formation of an abscess in the large intestine specifically has its causes; it invariably originates from Fire (Huo). When Fire is excessive and does not dissipate, it stagnates and condenses to form an abscess. However, the excess of Fire is fundamentally rooted in the deficiency of Water (Shui). When Water declines, Fire flares up; if Flaring Fire is unchecked, it nurtures toxicity that becomes difficult to resolve. Therefore, in treatment, why merely treat the Fire? By strengthening Water to control Fire, the toxic factors will naturally dissipate. Use the formula Qing Chang Yin (Clear the Intestines Decoction): Jin Yin Hua (Lonicerae Japonicae Flos, 3 liang), Dang Gui (Angelicae Sinensis Radix, 2 liang), Di Yu (Sanguisorbae Radix, 1 liang), Mai Dong (Ophiopogonis Radix, 1 liang), Xuan Shen (Scrophulariae Radix, 1 liang), Sheng Gan Cao (Glycyrrhizae Radix et Rhizoma Preparatum, 3 qian), Yi Ren (Coicis Semen, 5 qian), Huang Qin (Scutellariae Radix, 2 qian). Decoct in water and take orally. After one dose, pain subsides slightly; after two doses, the leg can extend; after another two doses, the toxicity is completely eliminated. This formula consists entirely of Yin-nourishing substances and acts as blood-invigorating and detoxifying agents. Although it purges Fire, it essentially nourishes Yin. Thus, they complement each other to achieve success, which is why the efficacy is miraculous. If one does not nourish Yin to moisten the intestines, but only attacks toxicity to reduce Fire, the large intestine will be damaged first, and how could it withstand the scorching of Fire-toxicity? No wonder the more one treats, the less effective it becomes.
Another case involves a patient with an abscess in the large intestine, whose right leg cannot extend, suffering severe abdominal pain, discharging pus and blood, and experiencing anal pain like knife cuts. This indicates that the intestinal abscess has already ulcerated. Those who can eat will survive; those who cannot eat will die. Nevertheless, among those who cannot eat, there are cases not caused by blazing Fire-toxicity, so one should not abandon them simply because they cannot eat. Generally, for any kind of carbuncle or sore, having Stomach Qi (Wei Qi) is auspicious. Without Stomach Qi, whether it is Yin-toxicity or Yang-toxicity, it is incurable. Therefore, when treating Yin-Ju (Yin-type ulcers), the primary method must be to support Stomach Qi, adding only a small amount of drugs that eliminate pus and remove toxicity. In this way, the healthy Qi remains unharmed, and Fire-toxicity disperses. Now, since the large intestine abscess has ruptured, leading to a loss of appetite, Stomach Qi is nearly exhausted, which is a critical condition. If one does not urgently tonify the Stomach but only treats the abscess, it is a path to death. Use the formula Kai Wei Jiu Wang Tang (Open the Stomach and Rescue from Peril Decoction): Ren Shen (Panacis Ginseng Radix, 1 liang), Jin Yin Hua (Lonicerae Japonicae Flos, 2 liang), Shan Yao (Dioscoreae Rhizoma, 1 liang), Sheng Gan Cao (Glycyrrhizae Radix et Rhizoma Preparatum, 3 qian), Yi Ren (Coicis Semen, 1 liang), Xuan Shen (Scrophulariae Radix, 1 liang), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 1 liang), Shan Yang Xue (Capra Hircus Blood, ground into powder, 1 qian). Decoct in water and take mixed with the powder. After one dose, the stomach opens; after two doses, pus decreases; after three doses, pain stops; after four doses, full recovery occurs. This formula focuses entirely on rescuing the Stomach, while eliminating pus and removing toxicity is included within it. The brilliance lies in Jin Yin Hua (Lonicerae Japonicae Flos); although it treats toxicity, it is also a Yin-nourishing herb. For patients with sores, it is a matter of life and death. It is like a benevolent and brave general in the army. With the assistance of Ren Shen (Panacis Ginseng Radix) and Bai Zhu (Atractylodis Macrocephalae Rhizoma) to boost its power, dispersing toxicity becomes especially miraculous. Shan Yang Xue (Capra Hircus Blood) stops bleeding, relieves thirst, and promotes Qi circulation, guiding the various herbs into the abscess to dissolve it, acting as a wise guide. Combined in treatment, there are those who harmonize, those who pacify, and those who attack. How could it fail to produce miraculous results? Naturally, Stomach Qi opens widely, transforming fine essences and transporting them to the large intestine. If Stomach Qi is not injured, taking this formula yields rapid effects. Do not doubt or fear using this formula, lest you waste lives.
Another case involves a patient with an abscess in the large intestine, severe lower abdominal pain, continuous dripping (of pus/blood), diminished spirit, tasteless diet, sallow complexion, weak limbs, spontaneous sweating, night sweats, and inability to sleep at night. People assume it is due to excessive Fire generating the abscess, but who knows it is actually due to deficient Water failing to moisten the intestines. The ability of the large intestine to conduct waste relies entirely on the irrigation of Kidney Water (Shen Shui). Now, due to overindulgence in alcohol and rich food, along with sexual exhaustion, causing severe damage to essence and substantial loss of Jing (Essence), Fire stirs while Water dries up. Furthermore, consuming cold and raw foods leads to disharmony of Qi and Blood, movement of Dampness, generation of Phlegm, obstruction of the intestines and stomach, failure of transformation and transportation, and stagnation of Qi and Blood, resulting in an abscess. However, before the abscess formed, there was already a deficiency of Kidney Water; after the abscess ulcerated, Water was further lost. This is deficiency exacerbating deficiency. If treated as chronic toxicity, it rarely fails to become a fatal condition. One must greatly tonify Kidney Water and simultaneously tonify the Qi of the Spleen and Stomach. Then, the Spleen and Stomach transform fine essences, making the generation of Water easier. The withered intestines will suddenly receive abundant moisture, becoming naturally sufficient. There is no need to specifically treat the abscess; it will resolve itself. With sufficient Qi and Blood, muscles will grow. Use Liu Wei Di Huang Wan (Six-Ingredient Rehmannia Pill) with modifications: Shu Di Huang (Rehmanniae Radix Preparata, 2 liang), Shan Yao (Dioscoreae Rhizoma, 8 qian), Mu Dan Pi (Moutan Cortex, 6 qian), Shan Zhu Yu (Corni Fructus, 8 qian), Fu Ling (Poria, 3 qian), Ze Xie (Alismatis Rhizoma, 1 qian), Ren Shen (Panacis Ginseng Radix, 1 liang), Huang Qi (Astragali Radix, 5 qian), Mai Dong (Ophiopogonis Radix, 1 liang). Decoct in water. Take continuously for several doses. Abdominal pain stops, spirit strengthens, and previous symptoms are instantly resolved. This formula uses the six ingredients to tonify Kidney Water, and adds Ren Shen (Panacis Ginseng Radix), Mai Dong (Ophiopogonis Radix), and Huang Qi (Astragali Radix) to tonify the Earth of the Spleen and Stomach. When Earth is prosperous, Lung Qi naturally prospers. The Lung and Large Intestine are exterior-interior pairs, and the Lung is the mother of the Kidney. Naturally, mother and son support each other, and exterior and interior care for each other, thus producing miraculous results.
