方用转气汤。
人参（三钱） 茯苓（三钱，去皮） 白术（三钱，土炒） 当归（五钱，酒洗） 白芍（五钱，酒炒） 熟地
（一两，九蒸） 山萸（三钱，蒸） 山药（五钱，炒） 芡实（三钱，炒） 柴胡（五分） 故纸（一钱，盐水炒）
水煎服。三剂效，十剂痊。此方皆是补血补精之品，何以名为转气耶？不知气逆由于气虚，乃是肝肾之气虚也。
补肝肾之精血，即所以补肝肾之气也。盖虚则逆，旺则顺，是补即转也；气转而各症尽愈，阴出之阳，则阴阳无捍格
之虞矣。
眉批∶方妙不可加减。白芍宜炒炭用。
歌括∶产后四肢皆浮肿，咳嗽吐酸两胁痛。
寒热往来阴阳捍，气血大亏肾水空。
转气白芍和熟地，参苓术归与芡实。
山药山萸柴胡配，再加盐炒补骨脂。
产后出现四肢浮肿，伴有寒热交替往来，气喘咳嗽，胸膈部感觉不畅，口中吐出酸水，两侧胁肋疼痛。人们都说是败血流入经络，渗入四肢，导致气机逆乱。殊不知这是肝肾两虚，阴液不能制约阳气（即阴不敛阳）的缘故！
凡是产后的妇女，气血严重亏损，自然会导致肾水不足，肾水沸腾；然而水不足就不能滋养肝木，导致肝木极度干燥，肝中缺乏津液滋润。肝燥则火发，肾火有党（指相火），子母同病，两脏之火相互焚烧，火焰直冲而上克制肺金。肺金受到火的刑克，力量难以制约肝木，于是咳嗽、喘促、胀满的病症就产生了；肝火既然旺盛，向下克制脾土，脾土受到木的刑克，力量难以制约肾水，于是四肢浮肿的病症就出现了。
然而，肝木之火的旺盛，是假象而非真正的旺盛。这种假旺之气，看似盛实则不足，所以时而发热时而发冷，寒热往来没有定数，这是随着气的盛衰变化而产生寒热反应。这里的寒并非真寒，热亦非真热，只是气机在胸膈之间逆乱而不舒畅罢了。两胁是肝的部位，酸味是肝的气味。吐酸水和胁肋疼痛，都是肝虚而肾不能滋养肝的表现。
治疗方法应当补血以养肝，补精以生血，精血充足了，气机自然顺遂，那么寒热、咳嗽、浮肿等病症都会消退。
方剂用转气汤。
人参（三钱）、茯苓（三钱，去皮）、白术（三钱，土炒）、当归（五钱，酒洗）、白芍（五钱，酒炒）、熟地黄（一两，九蒸）、山茱萸（三钱，蒸）、山药（五钱，炒）、芡实（三钱，炒）、柴胡（五分）、故纸（一钱，盐水炒）。
用水煎服。服用三剂见效，十剂痊愈。这个方子全是补血补精的药物，为什么命名为“转气”呢？不知道气逆是因为气虚，具体是肝肾之气虚。补益肝肾的精血，就是补益肝肾之气的方法。因为虚则气逆，旺则气顺，所以补益即是转化（使气顺）；气机转化后各种症状全部痊愈，阴能出阳（阴阳调和），就没有阴阳格拒的忧虑了。
眉批：此方妙处在于不可随意加减。白芍宜炒成炭使用。

Postpartum edema of the four limbs, alternating chills and fever (alternating aversion to cold and fever), asthma and cough, discomfort in the chest and diaphragm, spitting out sour fluid, and pain in both hypochondriac regions. People generally attribute this to residual blood entering the meridians and seeping into the four limbs, causing qi rebellion. Little do they know that this is due to deficiency of both the Liver and Kidney, where Yin fails to control Yang (Yin failing to anchor Yang).
In postpartum women, Qi and Blood are severely depleted, naturally leading to insufficient Kidney Water, which then boils; however, when Water is insufficient, it cannot nourish Liver Wood, causing Liver Wood to become extremely dry and lacking in fluids within the Wood. Dryness of Wood generates Fire, and with Kidney Fire as its ally, the mother and child organs burn each other. The flames rush upward to attack Lung Metal. Lung Metal, subjected to Fire's punishment, lacks the strength to control Liver Wood, giving rise to diseases such as cough, wheezing, and distension. Since Liver Fire is vigorous, it attacks Spleen Earth downward; Spleen Earth, subjected to Wood's punishment, lacks the strength to control Kidney Water, resulting in the disease of edema of the four limbs.
However, the vigor of Liver Wood's Fire is a false appearance, not true excess. This falsely excessive Qi appears abundant but is actually deficient; thus, there are times of heat and times of cold, with alternating chills and fever without fixed patterns. This alternation follows the fluctuation of Qi's abundance and deficiency. The cold here is not true cold, nor is the heat true heat; rather, it is simply Qi rebelling and stagnating in the chest and diaphragm, causing discomfort. The hypochondriac regions are the domain of the Liver, and sourness is the flavor associated with the Liver. Spitting sour fluid and hypochondriac pain are both manifestations of Liver deficiency and the Kidney's failure to nourish it.
The treatment method should involve tonifying Blood to nourish the Liver and tonifying Essence to generate Blood. When Essence and Blood are sufficient, Qi will naturally flow smoothly, and all symptoms such as chills, fever, cough, and edema will recede.
Use the Formula for Transforming Qi (Zhuanqi Tang).
Ren Shen (Ginseng Radix) (3 qian), Fu Ling (Poria) (3 qian, peeled), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (3 qian, stir-fried with soil), Dang Gui (Angelicae Sinensis Radix) (5 qian, washed with wine), Bai Shao (Paeoniae Radix Alba) (5 qian, stir-fried with wine), Shu Di Huang (Rehmanniae Radix Praeparata) (1 liang, steamed nine times), Shan Yu Rou (Corni Fructus) (3 qian, steamed), Shan Yao (Dioscoreae Rhizoma) (5 qian, stir-fried), Qian Shi (Euryales Semen) (3 qian, stir-fried), Chai Hu (Bupleuri Radix) (0.5 qian), Gu Zhi (Psoraleae Fructus) (1 qian, stir-fried with salt water).
Decoct in water and take orally. Effective after three doses, cured after ten doses. This formula consists entirely of substances that tonify Blood and Essence. Why is it named "Transforming Qi"? It is unknown that Qi rebellion stems from Qi deficiency, specifically deficiency of Liver and Kidney Qi. Tonifying the Essence and Blood of the Liver and Kidney is precisely the method to tonify their Qi. Deficiency leads to rebellion, while vigor leads to smooth flow; thus, tonification is transformation. Once Qi transforms, all symptoms heal, Yin emerges to harmonize with Yang, eliminating any concern for Yin-Yang rejection.
Marginal Note: The efficacy of this formula lies in its precision; it should not be arbitrarily modified or added to. Bai Shao should preferably be used charred.
Verse:
Postpartum edema affects all four limbs,
Coughing, spitting sour fluid, and pain in both hypochondria.
Alternating chills and fever indicate Yin-Yang conflict,
Great depletion of Qi and Blood leaves Kidney Water empty.
Zhuanqi uses Bai Shao and Shu Di,
Along with Ren Shen, Fu Ling, Bai Zhu, Dang Gui, and Qian Shi.
Shan Yao and Shan Yu Rou paired with Chai Hu,
Plus Psoralea stir-fried with salt water.
