猪苓（十八铢，去皮） 泽泻（一两六铢） 白术（十八铢） 茯苓（十八铢） 桂枝（半两，去皮） 上五味，
捣为散，以白饮和服，方寸匕，日三服，多饮暖水，汗出愈。如法将息。服散取其停留胸中，多饮暖水，取其气散营卫。
太阳病，发汗后，大汗出，胃中干，烦躁不得眠，欲得饮水者，少少与饮之，令胃气和则愈。若脉浮，
小便不利，微热消渴者，以五苓散主之。胃中干而欲饮，此无水也，与水则愈，小便不利而欲饮，此蓄
水也，利水则愈。同一渴，而治法不同，盖由同一渴，而渴之象不同，及渴之余症，亦各不同也。
发汗已，脉浮数，烦渴者，五苓散主之。汗不尽，则有留饮。
中风发热，六、七日不解、而烦，有表里证，渴欲饮水，水入则吐者，名曰水逆，胸中有水，则不能
容水矣。五苓散主之。桂枝治表，余四味治里。多饮暖水汗出愈，表里俱到。
本以下之，故心下痞，与泻心汤，痞不解，其人渴而口燥烦，小便不利者，五苓散主之。治痞而痞不
解，反渴，则为水停心下之故，非痞也。
太阳病，寸缓、关浮、尺弱，皆为虚象。其人发热汗出，复恶寒、不呕，但心下痞者，此以医下之
也，误治。如其不下者，病患不恶寒而渴者，此转属阳明也。此属实邪。小便数者，大便必硬，不更衣
十日，无所苦也，渴欲饮水者，少少与之，但以法救之，随症施治，不执一端。渴者与五苓散。如其渴不

霍乱头痛，发热，身疼痛，热多，欲饮水者，五苓散主之。此亦表里同治之法。
猪苓（十八铢，去皮） 泽泻（一两六铢） 白术（十八铢） 茯苓（十八铢） 桂枝（半两，去皮） 以上五味药，
捣碎成散剂，用米汤调和服用，每次一方寸匕，每日三次，服药后多喝温热水，出汗即愈。按照此法调养护理。服用散剂旨在使药力停留于胸中，多饮温热水，是为了借助水气宣散营卫之气。
太阳病（太阳经受邪所致的病证），发汗后，大汗出，胃中干燥，烦躁不得安睡，想要喝水的，少量多次给予饮水，令胃气调和则痊愈。如果脉象浮，
小便不通畅，轻微发热且口渴多饮的，以五苓散主治。胃中干燥而想喝水，这是体内缺水，给水则愈；小便不通畅而想喝水，这是水液停蓄，利水则愈。同样是口渴，但治疗方法不同，大概是因为同样是口渴，但口渴的表现不同，以及口渴伴随的其他症状也各不相同。
发汗之后，脉象浮数，心烦口渴的，五苓散主治。汗出不尽，则有留饮停滞。
中风发热，六、七天未解，并且烦躁，有表证和里证，口渴想喝水，水喝进去就吐出的，名叫水逆证，胸中有水饮，则不能容纳新入之水。五苓散主治。桂枝治疗表证，其余四味药治疗里证。多饮温热水出汗而愈，表里同治。
原本因为误用攻下法，导致心下部痞塞，给予泻心汤，痞塞不解，其人口渴且口燥心烦，小便不利的，五苓散主治。治疗痞证而痞塞不
解，反而出现口渴，则是由于水饮停聚在心下的缘故，并非单纯的痞证。
太阳病，寸脉缓、关脉浮、尺脉弱，都是虚象。其人发热汗出，又恶寒、不呕吐，只是心下部痞塞的，这是因为医生误用攻下法
所致，属于误治。如果不曾攻下，病人不恶寒而口渴的，这是转属阳明病（病邪传入阳明经腑）。这属于实邪。小便频数的，大便必定干硬，即使十天不大便，也没有痛苦，口渴想喝水的，少量多次给予饮水，只要按照法则救治，随症施治，不固执于一种方法。口渴的给予五苓散。如果口渴不止，五苓散也是一种治法。
霍乱头痛，发热，身体疼痛，热象较多，想喝水的，五苓散主治。这也是表里同治的方法。
Zhu Ling (Polypori Sclerotium, 18 zhu, peeled) Ze Xie (Alismatis Rhizoma, 1 liang 6 zhu) Bai Zhu (Atractylodis Macrocephalae Rhizoma, 18 zhu) Fu Ling (Poria, 18 zhu) Gui Zhi (Cinnamomi Ramulus, half liang, peeled). The above five herbs are
pounded into a powder. Mix with rice water and take orally. One fangcun bi (a measure of volume) per dose, three times daily. Drink plenty of warm water after administration; recovery occurs when sweat appears. Adjust care according to these instructions. Taking the powder aims to keep the medicinal effect lingering in the chest; drinking warm water helps disperse Ying and Wei (Nutritive and Defensive Qi) through the qi of water.
Taiyang disease (disease pattern caused by pathogenic invasion of the Taiyang channel), after inducing sweating, if profuse sweating occurs, leading to dryness in the Stomach, restlessness, inability to sleep, and desire for water, give small amounts of water frequently. When Stomach Qi harmonizes, the patient recovers. If the pulse is floating,
urination is difficult, accompanied by slight fever and excessive thirst, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Dryness in the Stomach with desire to drink indicates a lack of fluids; providing water leads to recovery. Difficulty in urination with desire to drink indicates retained water; promoting diuresis leads to recovery. Although both present with thirst, the treatment methods differ because the manifestations of thirst and accompanying symptoms vary.
After inducing sweating, if the pulse is floating and rapid, accompanied by irritability and severe thirst, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Incomplete resolution of sweating implies retained fluid retention.
Wind-stroke with fever, unresolved after six or seven days, accompanied by irritability, presenting both exterior and interior signs, with thirst and vomiting immediately after drinking water, is named Shui Ni (Water Reversal). Water accumulation in the chest prevents it from accommodating new water. Wu Ling San (Five-Ingredient Powder with Poria) is indicated. Gui Zhi (Cinnamon Twig) treats the exterior, while the other four herbs treat the interior. Drinking warm water to induce sweat resolves both exterior and interior conditions simultaneously.
Originally due to erroneous purgation, epigastric fullness and stuffiness occurred. Given Xie Xin Tang (Drain the Epigastrium Decoction), but the fullness did not resolve. If the patient experiences thirst, dry mouth, irritability, and difficulty in urination, Wu Ling San (Five-Ingredient Powder with Poria) is indicated. If treating fullness fails to resolve it, and thirst ensues, it is due to water retention in the epigastrium, not mere fullness.
In Taiyang disease, a slow pulse at the Cun position, floating at the Guan position, and weak at the Chi position all indicate deficiency patterns. If the patient has fever, sweating, aversion to cold, no vomiting, but only epigastric fullness, this results from the physician's erroneous purgation, constituting mismanagement. If no purgation was performed, and the patient is not averse to cold but is thirsty, the condition has transferred to Yangming disease (disease pattern involving the Yangming channels and organs). This represents excess pathogenic factors. Frequent urination leads to hard stools; even without defecation for ten days, there is no distress. For those desiring water, provide small amounts frequently. Rescue according to principles, treating based on specific symptoms without rigid adherence to a single method. For thirst, administer Wu Ling San (Five-Ingredient Powder with Poria). If thirst persists, Wu Ling San (Five-Ingredient Powder with Poria) remains one therapeutic option.
Huo Luan (acute vomiting and diarrhea syndrome) with headache, fever, body pain, predominant heat sensation, and desire for water is treated with Wu Ling San (Five-Ingredient Powder with Poria). This also employs a method of simultaneous treatment of exterior and interior conditions.
