面部浮肿属于风邪所致，足部浮肿属于湿邪所致。凡是浮肿从上部开始发展的，都是由于风邪引起，治疗重点在肺，适宜采用发散法，可用香苏饮合五皮饮。如果是从下部开始发展的，是由于肾虚导致水液泛滥，适宜采用渗湿利水法，可用五苓饮加防己、槟榔。全身都浮肿的，可能是先天禀赋不足突然遭受风寒侵袭，也可能是因为疟疾或痢疾导致脾虚，这些情况都能引起浮肿。病情较轻的用胃苓汤，病情较重的用加味胃苓丸。如果小儿元气本来虚弱，在大病之后出现浑身浮肿，四肢发冷，口不渴，小便清亮且量多，大便稀溏滑泄，不想吃东西，这是阴寒之邪已经极盛，脾胃功能即将衰竭，此时一切治疗浮肿的药物都不可使用，只能用四君子汤加青化桂（肉桂的一种）、炮姜、白蔻仁，来挽救脾胃功能，这样才有望存活。
凡是小儿患有浮肿，必须严格忌食盐，因为盐会助长火邪，服用后病情会更加严重，必须等到浮肿消退一个月后，才能少量使用经过盐炒制的盐。治疗水肿从脚部开始，若水气进入腹部则难以治愈：用红饭豆五升，煮得极其熟烂，取汤汁五升，浸泡双膝以下部位，凉了就要重新加热。如果治疗大腹肿胀，用红饭豆汤每天服用，肿胀自然会消退。
治疗脚肿：挖掘杉木根，切断后发现内部颜色发红的是油核，才可以药用，将红色的根切碎，煎煮浓汤，先将肿胀的脚熏蒸，然后清洗，肿胀即可消除。另一个方子：用红糖一大碗，加入生姜、生葱，三味药一起煎汤，先熏后洗。
头面手足全部浮肿：苦葶苈一两，隔纸炒熟，研成细末，用大红枣蒸过，去掉枣皮和枣核，将枣肉和药末混合捣碎制成如豆子大小的丸剂，每次服用七粒，用白开水送服，每天三次，五到七天后小便增多，浮肿自然消退。忌食碱味、酸味、生冷食物。
伤寒伤湿引起的浮肿：羌活切片，莱菔子等量，一起炒香，拣去莱菔子，只保留羌活研成粉末，每次服用一钱，第一天服一次，第二天服两次，第三天服三次即见效。
浮肿伴随气喘：无论男女老少，浮肿因积滞引起，既然已经去除积滞但浮肿再次发作，小便不利，切不可再使用利尿药物。这是因为中下二焦气机不升降，被阴寒痞塞阻隔，水液凝结不通。用熟附子三钱、生姜二钱、沉香三分，同煎浓汤服用。成人则用熟附子一两、生姜六钱、沉香七分，磨成浓汁，将姜汁和附子汁对半服用，不限次数，以痊愈为标准。
身体面部浮肿，坐卧不安：取向东生长的桑枝烧成灰，淋出汁液，用来煮红饭豆数升，每次饥饿时就吃这些豆子，不要喝其他汤水。
凡是水肿本源于脾虚，不能制约水液：应当以人参、白术补脾为主，脾气充实，就能健运，水液自然运行，切不可使用泻下法。
Facial edema is caused by Wind, while foot edema is caused by Dampness. Any edema that starts from the upper part is due to Wind; the treatment focuses on the Lung (Zang organ), and dispersing methods are appropriate, such as Xiangsu Yin (Fragrant Perilla Decoction) combined with Wupi Yin (Five Peel Decoction). Edema starting from the lower part is due to Kidney deficiency leading to water overflowing; permeating and draining methods are appropriate, such as Wuling Yin (Five-Ingredient Poria Decoction) added with Fangji (Stephania Root) and Binglang (Areca Seed). Generalized edema may result from congenital insufficiency suddenly exposed to Wind-Cold, or from Spleen deficiency due to malaria or dysentery, all of which can cause edema. For mild cases, Weiling Tang (Gastrodia and Atractylodes Macrocephala Decoction) is used; for severe cases, Jiawei Weiling Wan (Modified Gastrodia and Atractylodes Macrocephala Pills) is used. If a child has originally deficient Yuan Qi and develops generalized edema after a major illness, accompanied by cold limbs, no thirst, clear and profuse urination, loose diarrhea, and loss of appetite, this indicates extreme Yin-Cold and impending failure of the Spleen and Stomach. All drugs for treating edema should not be administered at this time; instead, Sijunzi Tang (Four Gentlemen Decoction) added with Qinghuagui (Cinnamon Twig), Pa Jiang (Prepared Ginger), and Baokouren (Amomum Fruit) should be used to rescue the Spleen and Stomach function, offering a hope for survival.
Whenever children suffer from edema, salt must be strictly avoided because salt aids Fire pathogenic factors, and consuming it will exacerbate the condition. Salt should only be used in small amounts after being stir-fried with salt, and only after the edema has subsided for one month. To treat edema starting from the feet, which becomes difficult to cure if water enters the abdomen: use five sheng of red rice beans, boil them until extremely soft, take five sheng of the decoction, and soak the area below both knees, reheating it when it cools. To treat abdominal distension and swelling, drink the red rice bean decoction daily until the swelling subsides naturally.
To treat foot edema: Dig up the root of the Chinese fir tree, cut it open, and if the inner color is red, it is called Youhe and can be used. Chop the red roots, decoct them into a strong liquid, fumigate the swollen foot first, then wash it, and the swelling will subside. Another prescription: Use one large bowl of brown sugar, add fresh ginger and green onions, decoct the three ingredients together, fumigate first, then wash.
For edema of the head, face, hands, and feet: Take one liang of Tingli (Periploca Seed), stir-fry it熟 through paper until cooked, grind it into fine powder. Steam large red dates, remove the skin and pits, mix the flesh with the powder, and pound into pills the size of beans. Take seven pills each time, washed down with plain boiled water, three times a day. After five to seven days, urination will increase, and the edema will naturally subside. Avoid alkaline, sour, and raw/cold foods.
For edema caused by Cold Damage and Dampness injury: Slice Qianghuo (Notopterygium Rhizome), mix with equal parts of Laifuzi (Radish Seed), stir-fry until fragrant, remove the Radish Seeds, keep only the Qianghuo, grind it into powder. Take one qian each time. Take once on the first day, twice on the second day, and three times on the third day for effectiveness.
Edema accompanied by asthma/panting: Regardless of gender or age, if edema is caused by accumulation, and recurs after the accumulation is removed, with difficulty in urination, diuretic drugs must absolutely not be used again. This is because the Qi mechanism of the Middle and Lower Jiao does not ascend and descend, blocked by Yin-Cold stagnation, causing water to condense and flow不通. Use three qian of Shu Fuzi (Prepared Aconite Root), two qian of fresh ginger, and three fen of Chenxiang (Aquilaria Wood), decoct strongly and administer. For adults, use one liang of Shu Fuzi, six qian of fresh ginger, and seven fen of Chenxiang, grind into strong juice, mix ginger and Aconite juices equally, and take without limit on dosage, stopping when cured.
For body and facial edema making sitting and lying uncomfortable: Take branches of mulberry trees facing east, burn them to ash, leach the ash to obtain juice, boil several sheng of red rice beans in this juice. Eat these beans whenever hungry, and do not drink any other liquids.
All edema originates from Spleen deficiency, failing to control water: The primary treatment should be tonifying the Spleen with Renshen (Ginseng Root) and Baizhu (Atractylodes Macrocephala Rhizome). When Spleen Qi is solid, it can transport and transform effectively, and water will move naturally. Purging methods must absolutely not be used.
