All disorders related to menstruation and pregnancy originate from the deficiency of Qi and Blood, and the weakness of the Spleen and Stomach. In the postpartum period, the depletion of Qi and Blood and the decline of Spleen and Stomach function are even more severe. Therefore, Zhu Danxi argued that the primary treatment for childbirth should be greatly tonifying Qi and Blood. Even if other symptoms exist, they should be treated as secondary issues.
Postpartum, due to worry, fright, fatigue, and overwork, Qi and Blood suddenly become extremely deficient, allowing various pathogens to easily enter through this deficiency. If the cause is Qi stagnation, treatment should specifically employ methods to move Qi and dissipate stagnation; if the cause is food retention, treatment should specifically employ methods to digest food and guide it out.
For heat patterns, Huangqin (Scutellariae Radix) and Lianzi (Coptidis Rhizoma) must not be used; for cold patterns, Guizhi (Cinnamomi Ramulus) and Fuzi (Aconiti Lateralis Radix Praeparata) must not be used. Using cold herbs will cause Qi and Blood stagnation, while using hot herbs will cause fresh blood to hemorrhage. Regarding external contractions or internal injuries, if Yangming/Taiyang/Shaoyang exterior symptoms appear, sweating therapy might seem applicable. However, using Mahuang (Ephedrae Herba) in the postpartum state would severely deplete Yang; if Yin interior symptoms appear, purging therapy might seem applicable, but using Chengqi Tang (Gastrointestinal Purge Decoction) in the postpartum state would severely deplete Yin.
Identifying hypochondriac pain: If caused by Kidney deficiency with lochia stasis, Chaihu (Bupleuri Radix) should not be used; delirium accompanied by sweating is a symptom of Yuan Qi (Original Qi) weakness mimicking pathogenic excess, and should not be treated as Stomach excess.
Jue syndrome (cold extremities) results from the decline of Yang Qi, making it difficult to distinguish between cold and heat patterns; only great tonification can restore Yang and recover health. Due to the deficit of Yin Blood, regardless of whether stiffness or flaccidity occurs, only nourishing Ying Blood can relax sinews and activate collaterals.
Furthermore, alternating chills and fever occurring at regular intervals mimic malaria; treating it as malaria leads to prolonged and difficult recovery. Restlessness of the Shen (Spirit) and disordered speech mimic possession by evil spirits; treating it as such leads to imminent danger.
Excessive blood loss leading to dry, constipated stool requires adding Rongrong (Cistanche Deserticola) to Shenghua Tang (Decoction for Generating New Blood), not merely for moistening intestines and promoting Qi movement, but to tonify blood and unblock bowels. Excessive sweating leading to scanty, dysuric urine requires doubling the dosage of Renshen (Ginseng Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma) in Liujunzi Tang (Six Gentlemen Decoction) to generate fluids and promote urination. Adding Renshen to Shenghua Tang and administering it frequently can rescue postpartum critical conditions, prolong life, and has been repeatedly proven effective.
Individuals unable to eat for long periods presenting with hernia or rectal prolapse usually suffer from Yuan Qi deficiency and sinking of Middle Qi, requiring Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). Trismus and clenched fists, if resembling wind syndrome due to Blood dryness, still rely on Shenghua Tang added with Renshen. Severe pain in the vagina due to wind invasion warrants Qianghuo Yangrong Tang (Notopterygii and Codonopsis Nourishing Ying Decoction). Cold injury to the vulva causing inability to close requires Shechuangzi (Cnidii Fructus), Tusi (Cuscutae Semen), Shanzhuyu (Corni Fructus), and Liuhuang (Sulfur). Palpitations and fright warrant adding Dingzhi Wan (Calming Spirit Pill) components to Shenghua Tang. Mental confusion mimicking spirit possession warrants Anshen Wan (Calming Spirit Pill) assisting Guipi Tang (Restore the Spleen Decoction). Chest fullness and deficiency due to Qi stagnation warrant adding Muxiang (Aucklandiae Radix) as an assistant herb to Shenghua Tang. Belching, sour regurgitation, and food aversion due to food retention warrant adding Shenqu (Massa Medicata Fermentata) and Maiya (Hordei Fructus Germinatus) to Liujunzi Tang.
Shortness of breath calls for Renshen combined with Shenghua Tang and Xingren (Armeniacae Semen Amarum). Shortness of breath with sweating calls for adding Fumai (Tritici Levis Fructus) and Magen (Hemp Root). If internal deficiency is profound with deep external contraction, Renpi Ningfei Tang (Ginseng Lung-Calming Decoction) is applicable. Cough calls for Shenghua Tang plus Xingren, Jiegeng (Platycodonis Radix), and Zhimu (Anemarrhenae Rhizoma). Phlegm-cough with sweating calls for adding Banxia (Pinelliae Rhizoma), Dazao (Ziziphus Jujubae Fructus), Renshen, and Baizhu. Dry cough with severe heat calls for Jiawei Siwu Tang (Modified Four Substances Decoction). Diarrhea with resolved abdominal mass-pain calls for酌情 (discretionary use of) Renshen, Baizhu, Rougu (Myristicae Semen), and Hezi (Terminalia Chebulae Fructus). Dysentery with tenesmus, if urgent, calls for decocting Muxiang, Baifuling (Poria), and Chenpi (Citri Reticulatae Pericarpium). Mastitis swelling and pain require two formulated prescriptions: before suppuration, Gualou (Trichosanthis Radix), Rushen (Mastix), and Moyao (Myrrha); after suppuration, Dabu Jinhua Wan (Great Tonifying Golden Flower Pill).
Vomiting and anorexia are divided into two syndromes: Qi stagnation uses Jiawei Liuhe Tang (Modified Six Harmonies Decoction); Blood stagnation uses Angwei Xingxue Tang (Stomach-Calming and Blood-Activating Decoction). One must know that Sumu (Sappan Lignum), Sanleng (Sparganii Rhizoma), and E'zhu (Curcumae Rhizoma) strongly break blood stasis, while Qingpi (Citri Reticulatae Pericarpium Viride) and Zhishi (Aurantii Fructus Immaturus) best eliminate distension. One must recognize that formulas consuming Qi and breaking Blood damage Ying and Wei (Defensive) Qi; these are only suitable for robust young adults, never for women during pregnancy or postpartum.
Generally, after recent childbirth, one must inquire about the status of Lochia. If mass-pain from stasis remains, Shaoyao (Paeoniae Radix Alba) and Baizhu should not be abruptly added. If abdominal pain ceases, Buzhong Yiqi Tang is undoubtedly appropriate. For Yang collapse with profuse sweating and Qi deficiency with panting, Jiashen Shenghua Tang (Shenghua Decoction with Added Ginseng) is a provisional measure. For Yang collapse with high fever and bloody flooding with syncope, rapidly decocting the original Shenghua Tang is an emergency rescue. Treatment methods should follow Danxi's principle of consolidating the root, and administration should emulate Taipu (Li Zhongzi) by increasing frequency.
