蚕茧汤通治三消之证。用蚕茧壳，或取丝绵结块者，取来煎汤，时时当茶饮，饮至二七，无不愈者。盖
此物与马同气，皆属午火，在人为少阴君火，善伏膀胱之火，引阴液上潮于口，而渴自止。昧者以为膀胱之火
作祟，不知膀胱之火，不能收摄，已随小便而去，惟其不能上潮，所以津液不生而口作渴。不观仙家运用三昧
真火，以心为君火，命门相火，膀胱民火；起火必自膀胱始，而后相火、君火，三火齐发； 炼阴魔，真火熏
蒸，甘露自降，何渴之有？
消渴日夜饮水无度，用猪肚一个，洗极
净，入淡豆豉五钱在内，以线缝之，煮极烂，取汁饮之。肚亦可食。
又方 煮猪血清汤，不入油盐，多饮极效。此物善能滋阴降火，专走血分。脾气虚者，间日饮之，恐
防作泄故也。

蚕茧汤可以通治上消、中消、下消这三种消渴病症。使用蚕茧壳，或者选取丝绵结块的部分，拿来煎煮成汤，时常当作茶水饮用，喝到十四天（二七），没有不痊愈的。大概因为此物与马同气，都属于午火，在人体对应少阴君火，善于潜降膀胱中的火气，引导阴液向上滋润口腔，口渴自然停止。愚昧的人认为这是膀胱之火作祟，却不知道膀胱之火因无法收摄，已经随着小便排出了，只是因为它不能向上滋润，所以津液不生而口中干渴。没看过道家运用三昧真火的方法吗？以心为君火，命门为相火，膀胱为民火；起火必然从膀胱开始，然后相火、君火，三火同时发动；炼化阴魔，真火熏蒸，甘露自然下降，哪里还会有口渴呢？
消渴病日夜饮水无度，用一个猪肚，清洗极其干净，放入淡豆豉五钱在里面，用线缝合，煮得极烂，取汁液饮用。猪肚也可以吃。
另一个方子：煮猪血做成清汤，不放盐和油，大量饮用效果极佳。此物善于滋阴降火，专门作用于血分。脾气虚弱的人，隔天饮用一次，恐怕担心导致腹泻的缘故。
经典说：营气，是水谷精微所化生，调和于五脏，散布于六腑，才能进入脉管中。由脾生化，由心统率，由肝贮藏接受，由肺宣发布散，由肾施予排泄，濡润宣通，无不由此而来。凡是吐血的人，是营卫之气逆乱所致。大概心是血的主宰；肺是气的主宰。气主温煦，血主濡养，营养全身骨骼，灌溉筋脉，升降有常度，自然顺畅舒适。如果外感六淫邪气，内伤饮食，气机停留不行，血液壅滞不能濡养，因此热极涌泄，难免有妄动出血的祸患。况且气有余便是火，火侵袭血液，受热则妄行，向上奔涌而导致吐血。所以小儿吐血，因伤食引起的最多，因为阳明经多气多血。如果郁热在内逼迫，必然导致营血妄行，所以小儿吐血，属于胃热的占十之七八。更有还在襁褓之中就吐血的，多由于厚重的帷帐和温暖的房间，火气熏逼，或者过食辛辣之物，流注于乳房，婴儿饮奶后，积温而成热，热极向上崩溢，有的吐血、有的鼻衄、有的尿血、有的便血了。如果是久咳导致的咯血，这是肺虚所致，应当保肺滋阴。
肺朝百脉之气，肝统辖各经之血。脾胃受损，营卫虚损，所以血液失去正常轨道而妄行，如果出现气虚神疲乏力，嘴唇没有红色的情况，千万不要用寒凉药物，宜先用四君子汤救助其脾，脾土充实则血自止。
血虚的人，精神如旧，嘴唇舌头颜色正常。用四物汤加入人参、白术，补气就是生血的方法。
吐血，是胃中积热，火热逼迫血液妄行，所以从口吐出。宜清泻胃火，使血液回归经脉，盖血属阴，阴主沉降，凡是血证从下部排出的为顺证，从上部排出的皆为逆证，用清胃散。
鼻出血，是脾热传于肺，虚火上炎，血液运行于清窍，所以血从鼻出。宜用加味四君子汤。
有咳嗽并伴随吐血的情况，这是心肾水火不升降，火炎失控，肺胃干燥枯槁。宜用滋阴降火汤。切不可当作童子痨（肺结核）来治疗。
有大便下血的情况，粪便之前见血的是近血，大概来自大肠，用黄连解毒汤；粪便之后见血的是远血，从胃脘小肠来，用清胃散止血。久不止者，用补中益气汤加胡黄连。
Canjie Tang (Cocoon Decoction) can comprehensively treat the three types of Xiao Ke (Wasting-Thirst Syndrome): Shang Xiao (Upper Wasting-Thirst), Zhong Xiao (Middle Wasting-Thirst), and Xia Xiao (Lower Wasting-Thirst). Use the shells of silkworm cocoons, or select those that have formed clumps of silk floss. Boil them in water to make a decoction, and drink it frequently as tea. After drinking for fourteen days (two sevens), there is no case that does not recover. This is because this substance shares the same Qi as the horse, both belonging to Wu Fire (Fire element associated with the Horse zodiac sign). In the human body, it corresponds to Shao Yin Jun Huo (Ministerial Fire of Shaoyin Meridian). It is effective at subduing the fire in the Bladder, guiding Yin fluids upward to moisten the mouth, thereby stopping thirst. Ignorant people believe this is caused by fire in the Bladder, but they do not realize that the fire in the Bladder, unable to be retained, has already been expelled through urination. The issue lies only in its inability to ascend and moisten, resulting in a lack of Jin Ye (Body Fluids) and dry mouth. Have you not observed how Daoist practitioners utilize the Three Pure Fires? They regard the Heart as the Sovereign Fire, the Ming Men (Gate of Vitality) as the Ministerial Fire, and the Bladder as the Civilian Fire; ignition must begin from the Bladder, after which the Ministerial Fire and Sovereign Fire, along with the three fires, are activated simultaneously. By refining Yin demons and steaming with true fire, sweet dew naturally descends. How could there be thirst?
For Xiao Ke syndrome characterized by excessive day-and-night drinking, take one pig stomach, wash it extremely clean, insert five qian of Dan Dou Chi (Prepared Soybean) inside, sew it shut with thread, and boil until very soft. Drink the extracted juice. The stomach meat can also be eaten.
Another prescription: Boil pig blood into a clear soup without adding salt or oil. Drinking large amounts yields excellent results. This substance is good at nourishing Yin and descending fire, specifically acting on the Blood level. For those with Spleen Qi deficiency, drink it every other day to prevent diarrhea.
The Classics state: Ying Qi (Nutritive Qi) is refined from food and water. It harmonizes within the Five Zang Organs and spreads throughout the Six Fu Organs, allowing it to enter the vessels. It is generated by the Spleen, commanded by the Heart, stored by the Liver, distributed by the Lung, and excreted by the Kidney. Its moistening and unblocking functions all originate here. Hematemesis (vomiting blood) occurs due to the rebellion of Ying and Wei Qi (Defensive Qi). The Heart is the master of Blood; the Lung is the master of Qi. Qi provides warmth, while Blood provides nourishment. They nourish the entire body and irrigate tendons and vessels. With normal ascending and descending movements, everything remains smooth and comfortable. If affected externally by the Six Excesses (pathogenic factors) or internally by dietary injury, Qi stagnates and fails to move, causing Blood to stagnate and fail to nourish. Thus, extreme heat causes surging and bleeding, leading to reckless hemorrhage. Moreover, excess Qi transforms into Fire. When Fire invades Blood, the Heat causes reckless movement, rushing upward and resulting in hematemesis. Therefore, among children, hematemesis is most often caused by food retention, because the Yangming channels are abundant in Qi and Blood. If constrained heat forces inward, it inevitably causes reckless movement of Ying Blood. Hence, seventy to eighty percent of pediatric hematemesis cases belong to Stomach Heat. There are also infants still in swaddling clothes who vomit blood, mostly due to thick curtains and warm rooms where heat accumulates, or from overconsumption of spicy foods that flow into the breasts. After the infant drinks milk, accumulated warmth generates heat. Extreme heat surges upward, causing some to vomit blood, suffer epistaxis (nosebleeds), hematuria (blood in urine), or hematochezia (blood in stool). If hemoptysis (coughing up blood) persists for a long time, it is caused by Lung deficiency and should be treated by protecting the Lung and nourishing Yin.
The Lung receives Qi from all vessels, and the Liver commands Blood from all meridians. Damage to the Spleen and Stomach leads to deficiency of Ying and Wei Qi, causing Blood to leave its normal pathway and bleed recklessly. If there is Qi deficiency with mental fatigue and pale lips lacking redness, cold-natured herbs must be avoided. Instead, use Sijunzi Tang (Four Gentlemen Decoction) first to rescue the Spleen. Once the Spleen is solid, the bleeding will stop.
In cases of Blood deficiency, the spirit remains unchanged, and the lips and tongue appear normal. Use Siwu Tang (Four Substances Decoction) added with Renshen (Ginseng) and Baizhu (Atractylodes Macrocephala). Tonifying Qi is the method to generate Blood.
Hematemesis is caused by accumulated heat in the Stomach, where fire forces Blood to move recklessly, causing it to be vomited from the mouth. One should clear Stomach Fire to guide Blood back into the vessels. Since Blood belongs to Yin, and Yin governs descent, bleeding from the lower body is considered favorable (Shun), while bleeding from the upper body is unfavorable (Ni). Use Qingwei San (Stomach-Clearing Powder).
Epistaxis (nosebleed) occurs when Spleen Heat transmits to the Lung, causing deficient Fire to flare upward. Blood travels through the clear orifices, exiting through the nose. Use Jiawei Sijunzi Tang (Modified Four Gentlemen Decoction).
If coughing is accompanied by hemoptysis, this indicates that Water and Fire between the Heart and Kidneys are not ascending and descending properly. Uncontrolled Fire flares up, leaving the Lungs and Stomach dry and withered. Use Ziyin Jianghuo Tang (Nourish Yin and Descend Fire Decoction). Do not mistakenly treat this as Tongzi Lao (Pediatric Tuberculosis/Wasting-Thirst).
For hematochezia (blood in stool), if blood appears before the stool, it is called Jinxue (Near Blood), originating from the Large Intestine; use Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity). If blood appears after the stool, it is called Yuanxue (Far Blood), originating from the Stomach or Small Intestine; stop it with Qingwei San. For persistent cases that do not stop, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with Hulan (Picrorhiza Root).
