猪苓(去皮) 茯苓 阿胶 滑石(碎) 泽泻(各一两)
上五味。以水四升。先煮四味。取二升。去滓。内下阿胶。烊消。温服七合。日三服。
成注云。甘甚而反淡。淡味渗泄为阳。猪苓茯苓之甘。以行小便。咸味涌泄为阴。泽泻之咸。以泄伏水。滑利窍。
阿胶滑石之滑以利水道。
琥按上成注云。甘甚而反淡。以二苓之味。虽云甘而实淡故也。猪苓汤专于利水。则是上文云脉浮发热。非关表证
明矣。
后条辩云。猪苓汤之治。与太阳五苓散颇同。在太阳为寒水气化。不避桂术者。从寒也。在阳明为燥金气化。改桂
术为滑石阿胶者。从燥也。同是小便不利。而在太阳则从寒。在阳明则从燥。病机之际。各有气宜。医者可漫焉施。治
乎哉。
或问小便不利。其水亦蓄在膀胱中否。余答云。不然。太阳病小便不利。其水当蓄在膀胱之中。以膀胱为太阳之府
也。五苓散中有桂枝之热以通之。以桂枝为太阳经药也。兹者阳明病。小便不利。其水当积在胃下脘。以胃为阳明之府
也。故猪苓散中有滑石之寒以利之。以滑石为阳明经药也。
或又问云。水既积在胃。成注何以云。热客下焦也。余又答云胃中之水。虽有停积。终当入于小肠。但其水至阑门
分水之处。遂阻绝不行。不能渗入膀胱。以故小便不利。阑门分水之处。谓非下焦主之邪。乃今而知猪苓汤证之小便不
利。为肠胃中之水。不入膀胱而不利。非若五苓散证之小便不利。为膀胱中有水。气化不出而不利也。医者。能达是理。
则用药之道自明。
阳明病。汗出多而渴者。不可与猪苓汤。以汗多。胃中燥。猪苓汤复利其小便故也。(此承上文而言猪苓汤之禁。渴
欲饮水。小便不利者猪苓汤证也。然其证汗必不多。若汗出多。虽小便不利。不可与猪苓汤。何也。汗出既多。则胃中
水液外输。随饮随燥。津液少。以故作渴。复用猪苓汤以利小便。是重亡其津液。故示戒也。)
脉浮而迟。表热里寒。下利清谷者。四逆汤主之。(此条系真寒证。表热是假里寒是真。故与四逆汤主之。正文与注
见中寒论中)
若胃中虚冷。不能食者。饮水则哕。(此亦真寒之证。正文与注见中寒论中)
脉浮发热口干鼻燥。能食者。则衄(脉浮发热。此阳明经有风也。甚至口干鼻燥。经中之热炽矣。能食者。成注云。

(重出例)阳明病下之其外有热。(云云至)但头汗出者。栀子豉汤主之。(正文与注已见前)
(附后例)阳明病。发潮热。大便溏。小便自可。胸胁满不去者。小柴胡汤主之。
阳明病胁下硬满不大便而呕。舌上白苔者。可与小柴胡汤。(云云至)身 然而汗出解也。(上二条证。虽云阳明病
实少阳经病居多。故皆与小柴胡汤。正文与注见后第七卷少阳篇中)
阳明中风。脉弦浮大而短气。腹部满。胁下及心痛。(云云至)耳前后肿(云云至)与小柴胡汤。脉但浮。无余证者。
与麻黄汤。若不尿。腹满加哕者。不治。(此条阳明病。亦少阳证居多。至末后脉但浮云云。虽略兼太阳。终非主证。其
主证云。脉弦。胁下痛。耳前后肿。可见少阳经病偏重。故与小柴胡汤。正文与注见后第七卷少阳篇中)
阳明病。自汗出。若发汗小便自利者。此为津液内竭。虽硬不可攻之。当须自欲大便。宜蜜煎导而通之。若土瓜根。
及与大猪胆汁皆可为导(此条乃详言导法。以佐下法之穷也。阳明病自汗出者。不可发汗。若发其汗兼之小便自利者。
此为津液内竭。内指肠胃而言。汗泄于外。溺去于下。皆内耗其津液。故云竭也。津液既竭。则大便硬。不问而可知矣。
大便虽硬成注云。此非结热。不可攻之。当待其自欲大便时。遂因其势而行导之之法。如蜜煎土瓜根大猪胆。皆可用也。
或问小便自利。大便硬。何以不用麻仁丸。余答云麻仁丸治胃热。屎结于回肠以内。兹者胃无热。
证屎已近肛门之上。直肠之中。故云。因其势而导之也。)
Zhu Ling (Polyporus, with skin removed), Fu Ling (Poria), E Jiao (Donkey-hide Gelatin), Hua Shi (Talcum, crushed), Ze Xie (Alisma, each one tael).
The above five herbs. Use four sheng of water. First decoct the first four herbs, obtain two sheng of liquid, remove the dregs, add E Jiao, and melt it. Take seven ge warm, three times a day.
Cheng Wuji's commentary states: The sweet flavor is intense yet appears faint; the faint flavor promotes seepage and drainage, which belongs to Yang. The sweetness of Zhu Ling and Fu Ling is used to promote urination. The salty flavor induces vomiting and drainage, which belongs to Yin. The saltiness of Ze Xie is used to drain stagnant water. Hua Shi lubricates orifices.
E Jiao and Hua Shi are slippery and facilitate the flow of water passages.
Hu notes on Cheng Wuji's commentary: "Sweetness is intense yet appears faint" refers to the fact that although Zhu Ling and Fu Ling are described as sweet, their actual taste is faint. Zhu Ling Tang is specifically for promoting diuresis; thus, the "floating pulse and fever" mentioned earlier clearly do not relate to exterior syndromes.
The later treatise states: The treatment of Zhu Ling Tang is quite similar to Wu Ling San in Taiyang syndrome. In Taiyang syndrome, due to cold-water qi transformation dysfunction, Gui Zhi (Cinnamon Twig) and Bai Zhu (Atractylodes Macrocephala Rhizome) are not avoided, adhering to the nature of cold. In Yangming syndrome, due to dry-metal qi transformation dysfunction, Gui Zhi and Bai Zhu are replaced by Hua Shi and E Jiao, adhering to the nature of dryness. Both present with difficult urination, but in Taiyang syndrome, treatment follows cold; in Yangming syndrome, treatment follows dryness. At critical junctures of pathogenesis, there are appropriate qi transformations for each. How can physicians treat arbitrarily?
One asks: In difficult urination, is the water also retained in the Bladder? I answer: No. In Taiyang syndrome with difficult urination, water should be retained in the Bladder, as the Bladder is the fu-organ of Taiyang. Wu Ling San contains the heat of Gui Zhi to unblock it, as Gui Zhi is a herb of the Taiyang channel. Now, in Yangming syndrome with difficult urination, water should accumulate in the lower epigastrium of the Stomach, as the Stomach is the fu-organ of Yangming. Therefore, Zhu Ling Tang contains the cold property of Hua Shi to promote drainage, as Hua Shi is a herb of the Yangming channel.
Another asks: If water accumulates in the Stomach, why does Cheng Wuji say "heat lodges in the lower jiao"? I answer again: Water in the Stomach, although stagnant, eventually enters the Small Intestine. However, when water reaches the Lamen (gate where fluids divide), it becomes blocked and cannot flow, failing to seep into the Bladder, thus causing difficult urination. The Lamen area is not solely governed by pathogens of the lower jiao. From this, we understand that difficult urination in Zhu Ling Tang syndrome is due to water in the intestines and stomach not entering the Bladder, unlike Wu Ling San syndrome where difficult urination is due to water in the Bladder failing to undergo qi transformation. If physicians comprehend this principle, the rationale for medication will naturally become clear.
In Yangming syndrome, if there is profuse sweating and thirst, Zhu Ling Tang must not be administered. This is because profuse sweating causes dryness in the Stomach, and Zhu Ling Tang further promotes urination. (This follows the previous text to state the contraindications of Zhu Ling Tang. Thirst with desire to drink water and difficult urination constitute Zhu Ling Tang syndrome. However, in this syndrome, sweating is not profuse. If sweating is profuse, even with difficult urination, Zhu Ling Tang must not be given. Why? Profuse sweating leads to external loss of gastric fluids; drinking water is quickly dried up, resulting in scanty body fluids and thirst. Using Zhu Ling Tang to promote urination would further deplete body fluids, hence the warning.)
With a floating and slow pulse, exterior heat and interior cold, and diarrhea with undigested food, Si Ni Tang (Frigid Four Decoction) is the primary treatment. (This clause describes a true cold syndrome. Exterior heat is false, interior cold is true. Thus, Si Ni Tang is given. The main text and commentary are found in Zhong Han Lun.)
If the Stomach is deficient and cold, unable to accept food, drinking water will cause hiccups. (This is also a true cold syndrome. The main text and commentary are found in Zhong Han Lun.)
With a floating pulse, fever, dry mouth, and dry nose, and the ability to eat, epistaxis (nosebleed) will occur. (Floating pulse and fever indicate wind in the Yangming channel. Severe dry mouth and nose indicate intense heat in the channel. Ability to eat, according to Cheng Wuji, means the interior is harmonious. According to Zhang Zhongjing's method, Yangming syndrome with ability to eat is named Wind Strike. Severe wind-heat stagnating in the channel without transmitting inward will inevitably lead to epistaxis. Regarding this clause, Zhang Zhongjing provides no treatment method. Chang Qizhi in Bu Wang Lun suggests Huang Qin Tang (Scutellaria Decoction). My opinion is Xi Jiao Di Huang Tang (Rhinoceros Horn and Rehmannia Decoction).)
(Repeated Example) Yangming syndrome, after purgation, with exterior heat... only head sweating occurs, Zhi Zi Chi Tang (Gardenia and Fermented Soybean Decoction) is the primary treatment. (Main text and commentary already seen previously.)
(Later Appendix Example) Yangming syndrome, with tidal fever, loose stools, normal urination, and persistent fullness in the chest and hypochondrium, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is the primary treatment.
Yangming syndrome, with hardness and fullness under the hypochondrium, constipation, and vomiting, and a white coating on the tongue, may be treated with Xiao Chai Hu Tang... resolving with generalized sweating. (The above two conditions, though labeled Yangming syndrome, are mostly Shaoyang channel diseases. Hence, Xiao Chai Hu Tang is given. Main text and commentary are found in Volume 7, Shaoyang Chapter.)
Yangming Wind Strike, with wiry, floating, and large pulse, shortness of breath, abdominal fullness, pain in the hypochondrium and heart region... swelling around the ears... give Xiao Chai Hu Tang. If the pulse is only floating without other symptoms, give Ma Huang Tang (Ephedra Decoction). If there is anuria, worsening abdominal fullness, and hiccups, it is incurable. (This Yangming syndrome clause involves mostly Shaoyang symptoms. The final mention of "pulse only floating..." slightly involves Taiyang but is not the main syndrome. The main symptoms are wiry pulse, hypochondriac pain, and periauricular swelling, indicating predominant Shaoyang channel disease. Hence, Xiao Chai Hu Tang is given. Main text and commentary are found in Volume 7, Shaoyang Chapter.)
Yangming syndrome, with spontaneous sweating. If sweating is induced and urination is free, this indicates internal exhaustion of body fluids. Even if stool is hard, it must not be attacked with purgatives. One must wait for the patient's natural urge to defecate and use Mi Jian Dao (Honey Suppository) to guide passage. Alternatively, Tu Gua Gen (Trichosanthes Kirilowii Root) or Da Zhu Dan Jin (Large Pig Gallbladder Juice) can be used as guides. (This clause details guiding methods to supplement the limitations of purgation. Yangming syndrome with spontaneous sweating should not induce sweating. If sweating is induced along with free urination, this indicates internal exhaustion of body fluids, referring to the intestines and stomach. Sweat escapes outward, urine exits downward, both consuming internal fluids, hence "exhaustion." Once body fluids are exhausted, stool becomes hard, which is evident. Although stool is hard, Cheng Wuji notes this is not accumulated heat and must not be purged. Wait for the natural urge to defecate and guide the process顺势. Honey suppositories, Tu Gua Gen, and Large Pig Gallbladder can all be used. One asks: With free urination and hard stool, why not use Ma Ren Wan (Hemp Seed Pill)? I answer: Ma Ren Wan treats Stomach heat with fecal accumulation in the ileum. Here, there is no Stomach heat, and the feces are near the anus in the rectum. Hence, "guide according to the situation.")
