《既效方》记载：有人出现阴部肿胀，医生用赤玉涂抹患处，并让患者服用八味丸而痊愈。如果是久病导致的阴肿，病情已经无法救治，应当迅速艾灸水分穴。因为水分穴能够分别水谷，水谷不分所以导致阴肿。不仅仅是阴肿，身体其他部位也出现肿胀时，尤其应该紧急服用禹余粮丸。
《资生经》记载：治疗水肿只能针刺水沟穴，如果针刺其他穴位，待体内积水排尽后病人就会死亡。然而艾灸水分穴则有效。（艾灸水分穴是治疗水肿极为快捷良善的方法），它是关键的要穴。有一位内科医生为李先生治疗水肿，用药饮治疗无效，有一天忽然为他艾灸了水分穴和气海穴，第二天早上查看，肿胀已经消退殆尽。确实证明了水分穴能够治疗水肿。
《儒门事亲》记载：一名男子眼下肿胀，像卧蚕一样，戴人（张从正）说：眼睛下方属阴。水也属阴。臀部被认为是水的主宰，其肿胀波及到眼下也是必然的。这是由于在房事交接之时，劳累出汗后遭遇风邪，风邪侵入皮肤腠理，腠理受寒则闭塞，风邪不能排出，与水邪一同运行。（医经说：面部肿胀称为风，足胫肿胀称为水。张仲景将其命名为风水。）所以病症如此，如果不禁止房事就会死亡。
赵以德记载：嘉定沈氏，年龄十八岁，患胸部、腹部、身体和面部全部肿胀，医生治疗半个月多没有效果。我诊察他的脉象，六部脉都摸不到，使用紫苏、桔梗等药材煎服一盏，胸部有微微出汗，再服用则全身出汗，那平和正常的脉象全都显现出来，一两天后他的脉象完全平复。
《九灵山房集》记载：钟姓女子患病，腹胀如鼓，四肢消瘦得只剩骨头，医生有的认为是怀孕、有的是认为有虫积、有的是认为是痨病。项彦章诊察她的脉象后告诉她说：这是气机薄弱影响了血室。钟氏说：服用川芎、当归之类的药物积累多年，难道不是补血药吗？彦章说：失误在于没有顺调气机。气是通道，血是水液，气有一息不运行，那么血就有一息不能流动。医经说：气血同源而出但名称不同，所以治疗血病必须先顺调气机，使经络通畅，然后血才能运行。气是血的统帅，气行则血亦行，专门治疗血病是没有益处的。于是给予苏合香丸投服。三天后腰部作痛，彦章说：血想要运行了，急忙用芒硝、大黄峻猛攻逐，排出了污血累累如同瓜状的东西，数量可达几十枚，应手而愈。彦章之所以知道钟女的病，是因为脉象弦滑而且数。弦脉代表气结，滑脉代表血聚实邪。所以气行而后大下之则病愈。
The *Ji Xiao Fang* records: A person presented with swelling of the genitalia. The physician applied Chiyu (Red Jade) to the affected area and prescribed Bawei Wan (Eight-Ingredient Pill), resulting in a cure. If the genital swelling is due to chronic illness, the condition may be incurable; one should rapidly moxa the Shuifen (Water Separation) acupoint. This is because Shuifen facilitates the separation of water and grain; failure to separate them leads to genital swelling. Not only for genital swelling, but when other parts of the body also swell, it is especially urgent to administer Yuyuliang Wan (Yuzhu Grain Pill).
The *Zisheng Jing* records: For treating edema, one should only needle Shuigou (Water Ditch); if other acupoints are needled, once the water is exhausted, the patient will die. However, moxibustion on Shuifen is effective. (Moxibustion on Shuifen is an extremely swift and excellent method for treating edema), making it a crucial acupoint. An internal medicine physician treated Mr. Li for edema with herbal decoctions without effect. One day, he suddenly performed moxibustion on Shuifen and Qihai (Sea of Qi) acupoints. By the next morning, upon inspection, the swelling had vanished completely. It is indeed proven that Shuifen can treat edema.
The *Rumen Shiqin* records: A male patient presented with swelling under the eyes, resembling a lying silkworm. Dairen (Zhang Congzheng) said: The area under the eyes belongs to Yin. Water also belongs to Yin. The buttocks are considered the master of water; thus, swelling reaching the under-eye area is inevitable. This resulted from sexual intercourse during which exertion caused sweating, followed by exposure to Wind pathogen. The Wind entered the skin and interstices (Couli). When Couli are constricted by Cold, the Wind cannot exit and travels together with Water pathogens. (The Classics state: Swelling of the face is called Feng [Wind]; swelling of the lower legs is called Shui [Water]. Zhang Zhongjing named this Fengshui [Wind-Water].) Therefore, with such symptoms, if sexual activity is not prohibited, death will ensue.
Zhao Yi-de recorded: Shen from Jiading, aged eighteen, suffered from swelling of the chest, abdomen, body, and face. Physicians treated him for over half a month without effect. I palpated his pulse and found no pulse in any of the six positions. I administered a decoction containing Zisu (Perilla Leaf) and Jiegeng (Platycodon Root). After one cup, there was slight sweating in the chest; after a second dose, the whole body sweated, and the normal, harmonious pulses reappeared. Within one or two days, his pulse became completely level.
The *Jiu Lingshan Fangji* records: A woman surnamed Zhong suffered from abdominal distension like a drum, with limbs so emaciated they were skeletal. Physicians speculated she was pregnant, had intestinal parasites, or suffered from consumption (Lao disease). Xiang Yazhang palpated her pulse and stated: This is Qi deficiency affecting the Blood Chamber (Xueshi). Zhong said: I have taken Xiong (Chuanxiong) and Gui (Danggui) for years; are these not blood tonics? Yazhang replied: The error lies in failing to regulate Qi. Qi is the pathway; Blood is like water. If Qi fails to move for even an instant, Blood cannot flow for that instant. The Classics say: Qi and Blood originate from the same source but have different names. Therefore, treating Blood disorders requires first regulating Qi, ensuring the meridians are unobstructed so Blood can flow. Qi is the commander of Blood; where Qi moves, Blood follows. Treating only Blood is futile. He then administered Suhexiang Wan (Styrax Pill). Three days later, the patient complained of lower back pain. Yazhang said: The Blood is attempting to move; urgently administer Mangxiao (Natrii Sulfas) and Dahuang (Rhubarb Root) for a vigorous purge. The patient passed numerous dark, clotted blood masses resembling melons, numbering dozens, and recovered immediately. Yazhang knew the nature of Zhong's illness because her pulse was Wiry (Xian), Slippery (Hua), and Rapid (Shu). Wiry indicates Qi stagnation; Slippery indicates accumulation of solid pathogens in Blood. Thus, regulating Qi followed by purging led to recovery.
