（论一首）
论曰∶肛门者，主大行道，肺、大肠候也，号为通事令史。重十二两，长一尺二寸，广
二寸二分。应十二时。若脏伤热，则肛门闭塞大行不通，或肿缩入生疮。若腑伤寒，则肛门
开大行洞泄，肛门凸出，良久乃入。热则通之，寒则补之，虚实和平，根据经调理（方见二十
四卷中。）
（论一首 方二首）
论曰∶夫五脏六腑者，内应骨髓，外合皮毛肤肉。若病从外生，则皮毛肤肉关格强急。
若病从内发，则骨髓痛疼。然阴阳表里，内髓外皮，其病源不可不详之也。皮虚者寒，皮实
者热。凡皮虚实之，应主于肺大肠。其病发于皮毛，热则应脏，寒则应腑。
治皮虚主大肠病，寒气关格方。
蒴 根叶（切三升） 菖蒲叶（切三升） 桃叶皮枝（三升） 细糠（一斗） 秫米（三

上五味以水一石五斗，煮取米熟为度，大盆器贮，于盆上作小竹床子罩盆，人身坐床中
，周回四面将席荐障风，身上以衣被盖覆。若气急时，开孔对中泄气，取通身接汗可得两

一切劳冷悉治之。
治皮实主肺病热气方。

（一篇论述）
论述说：肛门，是大肠传导糟粕的通道，由肺和大肠所主司，被称为“通事令史”（负责传达事务的小吏）。其重量为十二两，长度为一尺二寸，宽度为二寸二分。对应一年中的十二个时辰。如果内脏受伤蕴热，则会导致肛门闭塞，大便不通；或者出现肿胀、收缩甚至生疮。如果六腑感受寒邪，则会导致肛门松弛开泄，导致大便洞泄不止，肛门脱出，许久才能回纳。对于热证应当采用通利的方法，对于寒证应当采用补益的方法，根据虚实情况使机体恢复平衡，依据经络理论进行调理（具体方剂见第二十四卷中）。
（一篇论述，两个方剂）
论述说：五脏六腑，内部与骨髓相应，外部与皮毛肌肉相合。如果病邪从外部侵入，则会导致皮毛肌肉部位气机阻滞、强直拘急。如果病邪从内部发生，则会导致骨髓疼痛。然而，阴阳表里之间，内连骨髓外连皮毛，疾病的根源不可不详细探究。皮肤虚弱者多表现为寒证，皮肤坚实者多表现为热证。凡是判断皮肤的虚实，主要应归属于肺和大肠。疾病发于皮毛，热证往往影响内脏，寒证往往影响六腑。
治疗皮肤虚弱主要涉及大肠病的寒气阻滞方。
蒴藋根叶（切碎三升） 石菖蒲叶（切碎三升） 桃树叶皮枝（三升） 细糠（一斗） 秫米（三升）
以上五味药，用水一石五斗，煮至米粒熟透为止，盛放在大盆器中，在盆上放置一个小竹床罩住盆口，人坐在竹床中，周围四面用席子遮挡风，身上用衣被覆盖。如果出现气急的情况，打开孔洞让热气排出，取全身出汗持续约两顿饭的时间。如此连续三天，将蒸过的药汁温热后使用。如果盆里的水不够热，可以在盆下安放炭火加热。此方不仅能治疗寒证，凡是皮肤一切劳损寒冷之症均可治疗。
治疗皮肤坚实主要涉及肺病热气方。
栀子仁 枳实 大青 杏仁 柴胡 芒硝（各二两） 生地黄 淡竹叶（切碎各一升） 玄参
以上十味药，用水九升煎煮，取汁三升，滤去药渣，加入芒硝，分三次服用。
(A Treatise)
It is stated: The anus serves as the pathway for the transmission of waste, governed by the Lung and Large Intestine, and is metaphorically referred to as the "Messenger Official" (a minor official responsible for conveying messages). It weighs twelve liang, measures one chi two cun in length, and two cun two fen in width, corresponding to the twelve double-hours of a day. If the internal organs are injured by heat, it may result in anal obstruction with constipation, or swelling, retraction, and ulceration. If the fu-organs are affected by cold, it may lead to anal laxity with profuse diarrhea, prolapse of the anus which returns only after a long time. For heat patterns, unblocking methods should be employed; for cold patterns, tonifying methods should be used. Balance should be restored based on deficiency and excess, following the meridians for regulation (see formulas in Volume 24).
(A Treatise, Two Formulas)
It is stated: The zang-fu organs internally correspond to the bone marrow and externally connect with the skin, hair, flesh, and muscles. If pathogens enter from the exterior, they cause obstruction and stiffness in the skin, hair, flesh, and muscles. If pathology originates from the interior, it causes pain in the bone marrow. Therefore, the relationship between yin-yang, exterior-interior, inner marrow, and outer skin requires detailed investigation. Deficiency in the skin manifests as cold, while excess in the skin manifests as heat. Determining the deficiency or excess of the skin primarily relates to the Lung and Large Intestine. When disease arises in the skin and hair, heat patterns tend to affect the zang-organs, while cold patterns tend to affect the fu-organs.
Formula for Treating Skin Deficiency Involving Cold Qi Obstruction of the Large Intestine:
Suo Luo Gen Ye (Folium et Radix Datiscae Canescens, cut into pieces, three sheng) Shi Chang Pu Ye (Folium Acori Tatarinowii, cut into pieces, three sheng) Tao Ye Pi Zhi (Folium, Cortex et Ramulus Persicae, three sheng) Xi Kang (Fine Bran, one dou) Shu Mi (Frumentum Sorghi Vulgaris, three sheng)
Take the above five herbs, add fifteen dan five dou of water, and boil until the rice is cooked. Store in a large basin. Place a small bamboo bed over the basin opening. Sit on the bamboo bed, shielding the surrounding area with mats to block wind, and cover the body with quilts. If shortness of breath occurs, open the hole to vent the steam. Aim for generalized sweating lasting approximately the time it takes to eat two meals. Repeat this for three days. Use the steamed medicinal liquid when warm. If the water in the basin is not hot enough, place charcoal fire beneath the basin. This formula not only treats cold but also addresses all conditions of chronic cold and fatigue affecting the skin.
Formula for Treating Skin Excess Involving Heat Qi of the Lung:
Zhi Zi Ren (Semen Gardeniae, two liang) Zhi Shi (Fructus Aurantii Immaturus, two liang) Da Qing (Radix Isatidis, two liang) Xing Ren (Semen Armeniacae Amarum, two liang) Chai Hu (Radix Bupleuri, two liang) Mang Xiao (Natrii Sulfas, two liang) Sheng Di Huang (Radix Rehmanniae Recens, one sheng) Dan Zhu Ye (Folium Lophatheri, cut into pieces, one sheng) Xuan Shen (Radix Scrophulariae, one sheng)
Take the above ten herbs, add nine sheng of water, and decoct to obtain three sheng of liquid. Strain out the dregs, add Mang Xiao, and divide into three doses.
