这是治疗水肿的第一方。但是必须两手寸关尺脉象浮而迟，足部趺阳脉象浮而数。诊断方法丝毫不能差错。服用一剂即见效，服用五剂完全痊愈。否则不可轻易使用这个秘方。大道是无私的，方剂本不应保密。然而黄帝有兰台石室之藏（指皇家秘府），长桑君（扁鹊之师）也有担心轻率尝试导致误治、以及泄露天地机密的双重顾虑。我公布此方，是为了等待能举一反三的人，并非认为这一张方子就可以包治天下。
天雄（制，一钱）、牡桂（去皮，二钱）、细辛（一钱）、麻黄（一钱五分）、甘草（炙，一钱）、生姜（二钱）、大枣（两枚）、知母（去皮，二钱）。用水二杯半，先煎麻黄，吹去浮沫，然后加入其他药物，煮至剩余八分药液时服用。日夜分三次服用。应当汗出，如果感觉像虫子在皮肤中爬行一样，病就好了。○水肿严重者，加防己二钱。
天雄补益上焦的阳气，并下行入肾，犹如天道下济而光明。但又担心下济之气潜藏而不返，所以取细辛那一茎直上的特性来升举它。牡桂温暖下焦的水湿，并上行通于心，犹如地轴向上旋转运行。但又担心其上出施用的力量如果潜藏而不返，则气不能外润而络脉空虚，所以用姜、枣、甘草，化生气液，以补养络脉。如果药力只止而不升，则气聚化为火，导致小便困难，所以用知母，滋阴以化阳，以通利小便。而且知母治疗浮肿，出自《神农本草经》，而《金匮要略》治疗历节风脚肿如脱与麻黄、附子并用，可以由此类推明白。此方即是仲景的桂枝甘草姜枣麻黄汤，加上知母一味药，主治功效截然不同，可知经方的变化如同龙一般神妙。
有一位八十多岁的老翁，传授给我一个奇方：用生金樱根，去掉粗皮一两半，吴风草三钱，极小且团结的香菌七枚，水煎服一剂，小便即通畅，水肿痊愈。○我仔细推究此方极为精妙。麻黄大发汗，而其根又能止汗；橘肉生痰壅滞气机，而其皮又能化痰顺气；蚕因风而僵死，反而能驱风如神。这是大开大阖的道理。从金樱子的大涩小便，即可悟知其根能大通小便。吴风草原名鹿衔草，能除湿热，所以《素问》中与泽泻、白术同用，以治疗酒风（饮酒所致之风证），更加精妙。至于小香菌这一味药，此物本是湿热所化，用于除湿祛热坠浊之中，同气相感，引导药力到达病所，一旦诸药药性发动，则湿热无处藏身，都从小便排出了。这一定是异人传授留下的，所谓“礼失而求诸野”（官方礼仪遗失，到民间去寻找）。可惜我没有亲自试验过。
This is the premier formula for treating edema. However, it is essential that the pulse at both wrists (Cun, Guan, Chi positions) is floating and slow, and the pulse at the foot's Duyang position (located on the dorsum of the foot) is floating and rapid. The diagnostic method must be precise without any error. One dose yields immediate results; five doses lead to complete recovery. Otherwise, this secret formula should not be used lightly. The Great Dao is impartial, and formulas should not be kept secret. Yet, the Yellow Emperor had the Lan Tai archives (imperial secret library), and Chang Sang Jun (Bian Que’s teacher) feared the errors caused by rash experimentation and the leaking of heavenly and earthly secrets. I present this formula awaiting those who can infer other cases from one example, not claiming that this single formula can cure all diseases.
Tianniong (Gongura Radix Preparata, 1 qian), Mugui (Cinnamomi Cortex, peeled, 2 qian), Xixin (Asari Radix et Rhizoma, 1 qian), Mahuang (Ephedrae Herba, 1.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried, 1 qian), Shengjiang (Zingiberis Rhizoma Recens, 2 qian), Dazao (Jujubae Fructus, 2 pieces), Zhimu (Anemarrhenae Rhizoma, peeled, 2 qian). Use two and a half cups of water. First decoct Mahuang, blow away the foam, then add the remaining herbs. Decoct until eight-tenths of the liquid remains. Take orally, divided into three doses throughout day and night. Sweating should occur; if one feels as if insects are crawling under the skin, the disease will be cured. ○ For severe edema, add Fangji (Stephaniae Tetrandrae Radix, 2 qian).
Tianniong tonifies the Yang Qi of the Upper Jiao and descends into the Kidney, resembling Heaven descending its brightness. Yet, fearing that the descending Qi might remain latent without returning, we use Xixin, which grows straight upward in a single stem, to lift it. Mugui warms the Water-Dampness of the Lower Jiao and ascends to connect with the Heart, resembling the Earth’s axis rotating upwards. Yet, fearing that its ascending application might remain latent without returning, causing Qi to fail to moisten externally and collateral vessels to become deficient, we use Shengjiang, Dazao, and Gancao to transform Qi and generate fluids, thereby nourishing the collateral vessels. If the medicinal force stops and does not ascend, Qi aggregates into Fire, leading to difficult urination; thus, we use Zhimu to nourish Yin and transform Yang, thereby promoting urination. Moreover, Zhimu’s treatment of swelling is recorded in the *Shennong Bencao Jing*, and in the *Jingui Yaolue*, it is used with Mahuang and Fuzi to treat Lijie Feng (joint pain syndrome) with feet swelling as if detached. This analogy clarifies the principle. This formula is essentially Zhongjing’s Guizhi Gancao Jiangzao Mahuang Tang, with the addition of one herb, Zhimu. The primary indications are completely different, demonstrating that the variations of classical formulas are as miraculous as dragons.
An old man over eighty years old transmitted a miraculous formula to me: use raw Jinyingen Gen (Chrysobalanus icaco Root), remove the coarse bark, 1.5 liang; Wu Feng Cao (Osmunda japonica, also known as Luxian Cao), 3 qian; very small and compact Xiangjun (Agaricus species mushrooms), 7 pieces. Decoct in water and take one dose. Urination becomes patent immediately, and edema resolves. ○ Upon careful reflection, this formula is extremely ingenious. Mahuang induces profuse sweating, yet its root can stop sweating; Tangerine pulp generates phlegm and obstructs Qi, yet its peel transforms phlegm and regulates Qi; Silkworms stiffen due to wind, yet they can dispel wind miraculously. This embodies the principle of great opening and closing. From the strong astringency of Jinyingzi (Chrysobalani Fructus) on urination, one can infer that its root strongly promotes urination. Wu Feng Cao, originally named Luxian Cao, can drain damp-heat; thus, in the *Suwen*, it is used with Zexie (Alismatis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) to treat Jiufeng (wind syndrome caused by alcohol consumption), which is even more exquisite. As for the single herb Xiangjun, this substance is transformed from damp-heat. Used to drain dampness, clear heat, and descend turbidity, it resonates with similar energies, guiding medicinal power to the site of pathology. Once the properties of the other herbs are activated, there is no room for damp-heat to hide; everything drains out through urination. This was likely passed down by an extraordinary person, illustrating the saying "When rites are lost, seek them in the wild." Regrettably, I have not tested it myself.
