胃，反与清肺，则脾气愈伤，不能统血，而为下脱泄泻之患。虚损已成，虽可久，复生恐难为力矣。
聂久吾的表侄，三十岁，起初咳嗽带血，服用滋养和清凉的药物后痊愈。忽然出现大便下血，血液在下部排出属于顺证，不要急于止血，半个月后，使用新制的脏连丸服用而治愈。配方为：黄连研成粉末，用酒拌入猪大肠中，上面覆盖韭菜，蒸烂后捣匀晒干，再研成粉末。每取黄连一两，加入侧柏叶末、当归末各二钱，混合均匀，用米糊制作成梧桐子大小的药丸，空腹时，用温酒或白开水送服二钱五分。
魏玉横说：赵正的妻子，年龄接近四十岁，便血，面色黄，四肢浮肿。凡是补气补血，以及气血双补、升提固涩、凉血温中的药剂，没有不尝试过的，其中归脾汤用得最多，但都很少见效。医书说，粪便之前的出血，病位较近；粪便之后的出血，病位较远。现在则是两者都有。诊脉发现，关前脉盛，关后脉衰，且脉象弦而数。我说：这不是脾不统血，而是肝木挟带火热上乘于胃，血液因此上逆。因为病人的肺气强盛，所以没有发生呕血，反而血液侧溢进入大肠导致便血。所以有时血液先注入，渣滓后注入，则便前有血；有时渣滓先注入，血液后注入，则便后有血；有时渣滓前后与血液同时注入，则便前后都有血。大概阳明经是多气多血的脏腑，虽然失血较多，但身体并不十分虚弱。只需峻补肝脏，使肝不挟火上逆，血液自然停止。给予生地黄、熟地炭、白芍、枣仁、枸杞子各五钱，炙甘草、酒黄芩各五分，川楝肉一钱，服用八剂后完全康复。
有一位少年长期患有便血，自己说接触污秽之物后腹痛，经过一天不止，于是寻找土医针刺委中穴，出血如注，随即大发寒热，头痛如被捣击，腹部和胁部胀满疼痛，不能翻身转动，胡言乱语像发疯一样。一位馆里的老师，用大柴胡汤攻下而治愈。痊愈后，不时出现寒热咳嗽，服用滋阴清肺的药物两个月，但咳嗽更加严重。最近饮食增多，大便泄泻并兼有下血，左右关尺脉皆弦细而数。张飞畴说：这一定是针刺委中穴时，感染了风寒，因为病人素有便血，邪气乘虚而入，形成热入血室，类似于阳明病下血谵语的情况。使用大柴胡汤得以痊愈是偶然中的，是“痛随利减”的效果，原本不是正确的治疗方法，所以痊愈后不时出现寒热咳嗽，脾胃清阳之气下陷，而肺失去通调输化的功能。这个时候如果不调理补益脾胃，反而清肺，则脾气更加受伤，不能统血，从而造成下脱泄泻的祸患。虚损已经形成，虽然可以维持很久，但要再生恢复恐怕很难有力气了。
Nie Jiuwu's cousin, aged thirty, initially presented with hemoptysis (coughing up blood), which resolved after taking nourishing and cooling medications. Suddenly, he experienced hematochezia (blood in stool). Since the blood was discharging from the lower orifice, this was considered a favorable pattern; thus, immediate hemostasis was not advised. Half a month later, he was cured by administering Xin Zhi Zang Lian Wan (New Formulated Intestine-Linking Pills). The preparation involves grinding Chuanlian (Corydalis Rhizome) into powder, mixing it with wine and pig large intestine, covering it with Chinese chives, steaming until soft, mashing uniformly, drying, and grinding back into powder. For every liang of Chuanlian, add two qian each of Ce Bai Ye (Biota Tops) powder and Dang Gui (Angelica Sinensis) powder, mix uniformly, bind with rice paste to form pills the size of wutong seeds. Take 2.5 qian on an empty stomach, washed down with warm wine or plain water.
Wei Yuheng stated: Zhao Zheng's wife, nearing forty years of age, suffered from hematochezia, yellow complexion, and edema of the limbs. She had tried all manner of tonifying Qi and Blood, dual-tonifying Qi and Blood, lifting and securing, cooling blood, and warming the middle agents, with Guipi Tang (Restore the Spleen Decoction) being the most frequently used, yet few showed efficacy. Medical texts state that blood appearing before stool indicates a proximal source, while blood appearing after stool indicates a distant source. In her case, both occurred. Upon pulse diagnosis, the pulse at Guan anterior was vigorous, while Guan posterior was deficient, and the pulse was wiry and rapid. I said: This is not due to the Spleen failing to control blood, but rather Liver Wood carrying fire to ascend upon the Stomach, causing blood to rebel upwards. Because the patient's Lung Qi was strong, she did not experience hematemesis (vomiting blood); instead, the blood spilled sideways into the Large Intestine, resulting in hematochezia. Thus, sometimes blood enters first and residue later, leading to blood before stool; sometimes residue enters first and blood later, leading to blood after stool; sometimes residue and blood enter simultaneously before and after, leading to blood both before and after stool. Generally, the Yangming channel is the residence of abundant Qi and Blood. Although significant blood loss occurs, the body does not become severely debilitated. One should merely strongly nourish the Liver to prevent it from carrying fire upwards, at which point bleeding will cease naturally. Prescribed were Sheng Di Huang (Rehmannia Root), Shu Di Tan (Charred Prepared Rehmannia Root), Bai Shao (White Peony Root), Zao Ren (Ziziphus Seed), and Qi Zi (Goji Berry) each at five qian, Zhi Gan Cao (Honey-fried Licorice Root) and Jiu Huang Qin (Wine-processed Scutellaria Root) each at five fen, and Chuan Liu Rou (Evodia Fruit) at one qian. After eight doses, full recovery was achieved.
A young man who had long suffered from hematochezia claimed that abdominal pain occurred after contact with filth, lasting more than a day without stopping. He sought a folk doctor who punctured the Weizhong (BL40) acupoint, causing blood to flow like a stream. Immediately thereafter, he developed severe chills and fever, headache as if being pounded, distension and pain in the abdomen and hypochondrium, inability to turn or move, and delirium resembling madness. A tutor in a school cured him using Da Chai Hu Tang (Major Bupleurum Decoction) to purge. After recovery, he intermittently experienced chills, fever, and coughing. Taking Yinzi Qingfei (Nourish Yin and Clear Lung) medications for two months worsened the cough. Recently, his food intake increased, but he suffered from diarrhea accompanied by hematochezia. The pulses at the left and right Guan and Chi positions were wiry, fine, and rapid. Zhang Feichou said: This must be due to contracting Wind-Cold during the puncture of Weizhong. Because the patient had pre-existing hematochezia, the pathogenic factor entered through the deficiency, forming Re Ru Xue Shi (Heat Entering the Blood Chamber), similar to the pattern of hematochezia and delirium in Yangming disease. The cure obtained with Da Chai Hu Tang was accidental, reflecting the principle that "pain decreases with purgation," but it was not the correct treatment. Therefore, post-recovery intermittent chills, fever, and coughing occurred because the clear Yang Qi of the Spleen and Stomach sank downward, and the Lung lost its function of regulating and distributing fluids. At this time, instead of regulating and tonifying the Spleen and Stomach, clearing the Lung was performed, which further injured Spleen Qi, causing it to fail to control blood, leading to prolapse, diarrhea, and leakage. The consumptive disease was already established; although it could persist for a long time, restoring vitality would likely be beyond power.
