凡病起于血气之衰、脾胃之虚，况产妇血气、脾胃其虚
衰殆有甚焉。是以丹溪先生论产后“必当以大补气血为先”，虽有杂症，以末治之。此三言者，尽医
产之大旨也。若能扩充立方用药，则治产可以无大过矣。夫产后忧惊劳倦，血气暴虚，诸症乘虚易袭。
如有气，毋专耗散；有食，毋专消导。热不可用芩、连，寒不可多桂、附。寒则血块停涩，热则新血
流崩。至若虚中外感，见三阳表症之多，似可汗也，在产后而用麻黄，则童竭其阳；见三阴里症之多，
似宜下也。在产后而用承气，则重亡阴血。耳聋胁痛，乃肾虚恶露之停，休用柴胡；谵语汗出，乃元
气弱似邪之症，毋同胃实。厥由阴阳之衰，难分寒热，非大补不能回阳而起弱； 因阴血之亏，勿论
刚柔，非滋荣不熊舒筋而活络。又如乍寒乍热，发作有期，症类疟也，若以疟治，迁延难愈。神不守
舍，言语无伦，病似邪也，若以邪论，危亡可待。去血多而大便燥结，苁蓉加于生化，非润肠承气之
能通；去汗多而小便短涩，六君倍用参、 ，必生津助血之可利。加参生化频服，救产后之危，长生
活命屡用，苏绝谷之症。颓疝脱肛，多是气虚下陷，补中益气是良方也。口噤拳挛，乃阴血燥类风，
加参生化大有益焉。产户入风而痛甚，服宜羌活养荣方；玉门伤冷而不闭，洗须床、菟、萸、硫黄。
怔忡惊悸，生化汤而加定志；似邪恍惚，安神丸助于归脾。因气喘而满闷虚烦，生化汤加木香为佐；
因过食而嗳酸恶食，六君子加神曲、麦芽为良。苏木、棱、莪、大能破血，青皮、枳壳，最消满臌。
一应耗气破血之剂，汗吐宣下之策，止可施于少壮，岂其宜用于胎产？大抵新产之后，先问恶露如
何？痛块未除，未可遽加参、术；腹中痛止，补中益气无疑。至若
亡阳脱汗，气虚喘促，频灌加参生化，是从权也；又如阴亡大热，血崩厥晕，速煎生化原汤，乃救急也。
王太仆云∶治下补下制贵以急，缓则滋道路而又力微。制急方而气味薄，则力与缓同。故治产当遵丹溪
而固本，服法宜效太仆以加频。凡负生死之寄者，可不着意以扶危哉。
凡是疾病都起因于血气的衰弱、脾胃的虚弱，何况产妇的血气、脾胃其虚衰程度恐怕更加严重。因此丹溪先生论述产后调理时指出：“必定应当以大补气血为优先”，即使伴有其他杂症，也将其作为次要问题来处理。这三句话，概括了治疗产后疾病的根本宗旨。如果能够在此基础上扩充思路以确立方剂、用药，那么治疗产后疾病就可以没有大的过失了。
产后因忧愁惊恐、劳累倦怠，导致血气突然极度虚弱，各种病症容易乘虚侵袭。如果体内有气滞，不要专门使用耗散气机的药物；如果有食积，不要专门使用消食导滞的药物。有热象不可滥用黄芩、黄连，有寒象不可多用桂枝、附子。因为寒凉会导致血块停滞不畅，温热过度则会导致新血流溢崩漏。
至于虚人感受外邪，出现三阳经表证较多的情况，看似可以用发汗法，但在产后如果使用麻黄，则会竭尽阳气；出现三阴经里证较多的情况，看似适宜用攻下法，但在产后如果使用承气汤类方剂，则会再次损伤阴血。
耳聋胁痛，是肾虚且恶露停滞所致，不要使用柴胡；谵语（说胡话）出汗，是元气虚弱似有邪气干扰的症状，不要当作胃实热证来治。厥证是由于阴阳衰竭引起的，难以分辨寒热属性，非大补元气不能回阳并挽救虚弱的身体；由于阴血亏损，不论属于刚痉还是柔痉，非滋养营血不能舒缓筋脉并疏通经络。
又如忽冷忽热，发作有定时，症状类似疟疾，如果用治疟疾的方法治疗，病情会拖延难愈。神志不守舍，言语错乱无条理，病状似中邪，如果按邪气论治，危亡就在眼前。
失血多而导致大便干燥结滞，在生化汤中加入肉苁蓉，这不是润肠通便或承气汤能做到的；出汗多而导致小便短少涩滞，六君子汤加倍用人参、[白术]，必须依靠生津助血才能通利小便。加人参的生化汤频繁服用，可以挽救产后的危重情况；长生活命散屡用有效，可以苏醒绝谷（无法进食）的病症。
颓疝和脱肛，多是气虚下陷所致，补中益气汤是良方。口噤（牙关紧闭）拳挛，是阴血燥盛类似风证的病症，加人参的生化汤大有益处。产户受风而疼痛剧烈，内服宜用羌活养荣方；玉门（阴道口）受冷而不能闭合，外洗需用床石、菟丝子、山茱萸、硫黄。
怔忡惊悸，用生化汤加入定志丸的成分；似邪恍惚，用安神丸辅助归脾汤。因气喘而导致胸闷虚烦，用生化汤加入木香作为佐药；因过食而导致嗳气酸腐、厌恶食物，用六君子汤加入神曲、麦芽为良方。苏木、三棱、莪术，最能破血行瘀；青皮、枳壳，最善消除胀满鼓胀。
所有耗气破血的药剂，以及汗、吐、宣、下的治法，只可施用于年轻力壮之人，岂适宜用于胎产之后？大抵在新产之后，先要询问恶露的情况如何？如果痛块未除，不可急于加入人参、白术；如果腹中疼痛停止，使用补中益气汤无疑是对的。
至于亡阳导致的脱汗，气虚引起的喘促，频繁灌服加人参的生化汤，这是权宜之计；又如阴液亡失导致的大热，血崩导致的厥晕，迅速煎煮生化汤原方，这是急救之法。王太仆说：治疗下部疾病，补益下焦的方制贵在急峻，缓慢则药力微弱且路途遥远。如果制成的急方气味淡薄，则药力与缓方相同。所以治疗产后疾病应当遵循丹溪先生的观点以固护根本，服药方法宜效法王太仆的观点以增加频次。凡是将生死重任寄托于医者的人，怎能不着力于扶危救困呢？
All diseases originate from the decline of blood and qi, and the deficiency of the spleen and stomach. How much more so is the deficiency and decline of blood, qi, spleen, and stomach in postpartum women? Therefore, Master Danxi stated in his discussion on postpartum care that "one must prioritize greatly tonifying blood and qi." Even if there are miscellaneous symptoms, they should be treated as secondary matters. These three words summarize the main principle of treating postpartum conditions. If one can expand upon this to formulate prescriptions and select herbs, then treating postpartum diseases will involve no major errors.
Postpartum sorrow, fright, fatigue, and overwork cause a sudden and severe deficiency of blood and qi, allowing various pathologies to easily invade due to this deficiency. If there is qi stagnation, do not exclusively use dispersing agents; if there is food retention, do not exclusively use digestive and guiding agents. For heat patterns, avoid using Huangqin (Scutellariae Radix) and Lianzi (Coptidis Rhizoma); for cold patterns, avoid excessive use of Guizhi (Cinnamomi Ramulus) and Fuzi (Aconiti Lateralis Radix Praeparata). Cold causes blood stasis and obstruction, while excessive heat causes new blood to flow uncontrollably (metrorrhagia).
Regarding exogenous pathogens invading a deficient body, presenting with many Taiyang (Greater Yang) exterior symptoms, sweating therapy might seem appropriate. However, using Mahuang (Ephedrae Herba) in the postpartum state would exhaust yang qi. Presenting with many Shaoyin (Lesser Yin) or Taiyin (Tai Yin) interior symptoms, purgative therapy might seem suitable. However, using Chengqi Tang (Gastrointestinal Releasing Decoction) variants in the postpartum state would severely deplete yin blood.
Deafness and hypochondriac pain indicate kidney deficiency with stagnant lochia; do not use Chaihu (Bupleuri Radix). Delirium and sweating indicate weak yuan qi resembling pathogenic interference; do not treat it as excess heat in the stomach. Jue syndrome (cold extremities/fainting) results from the decline of yin and yang, making it difficult to distinguish between cold and heat patterns; only great tonification can restore yang and revive the weak body. Due to yin blood deficiency, regardless of whether it presents as rigid or flexible spasms, only nourishing the Ying (Nutritive) level can relax the sinews and unblock the collaterals.
Similarly, alternating chills and fever with periodic onset resembles Malaria (Nüe Ji); treating it as malaria leads to prolonged difficulty in cure. Restlessness of the spirit and incoherent speech resemble possession by evil spirits; treating it as such predicts imminent danger and death.
Excessive blood loss leading to dry, constipated stool: adding Rongren (Cistanche Deserticola) to Shenghua Tang (Decoction for Generating Blood) achieves moistening and purging effects that Run Chang (Intestine Moistening) or Chengqi Tang cannot. Excessive sweating leading to scanty, dysuric urine: doubling the dosage of Renshen (Ginseng Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma) in Liu Jun Zi Tang (Six Gentlemen Decoction) generates fluids and assists blood to promote urination. Frequent administration of Shenghua Tang with added Renshen saves critical postpartum conditions; Changsheng Huoming San (Longevity and Life-Preserving Powder) frequently revives patients unable to eat.
Tui Shan (retracted testicles) and Tuogang (rectal prolapse) are mostly due to qi deficiency sinking; Buzhong Yiqi Tang (Middle-Boosting Qi-Supplementing Decoction) is an excellent prescription. Koujin (lockjaw) and quanan (clenched fists/spasms) resemble wind syndromes caused by dry yin blood; Shenghua Tang with added Renshen is highly beneficial. Severe pain in the vaginal orifice due to wind invasion requires internal administration of Qianghuo Yangrong Fang (Notopterygium Nourishing Nutritive Decoction); cold injury to the Yu Men (vaginal opening) causing inability to close requires external washing with Chuangshi (Bed Stone), Tusizi (Cuscutae Semen), Shanzhuyu (Corni Fructus), and Liuhuang (Sulfur).
Palpitations and fright are treated with Shenghua Tang combined with Dingzhi Wan (Stabilizing Spirit Pill);恍惚 (trance-like states resembling evil influence) are assisted by Anshen Wan (Calming Spirit Pill) combined with Guipi Tang (Restore the Spleen Decoction). Chest fullness and empty irritability due to asthma are treated with Shenghua Tang adding Muxiang (Aucklandiae Radix) as an assistant; belching sourness and aversion to food due to overeating are treated well with Liu Jun Zi Tang adding Shenqu (Massa Medicata Fermentata) and Maiya (Hordei Fructus Germinatus).
Sumu (Sappan Wood), Sanleng (Sparganii Rhizoma), and E'zhu (Curcumae Rhizoma) strongly break blood stasis; Qingpi (Citri Reticulatae Pericarpium Viride) and Zhike (Aurantii Fructus) best eliminate distension and bloating. All formulas that consume qi and break blood, as well as therapies involving sweating, vomiting, diffusing, and purging, are only applicable to young and robust individuals; how could they be suitable for pregnancy and childbirth?
Generally, after fresh delivery, first inquire about the status of lochia. If painful masses remain, do not hastily add Renshen and Baizhu. If abdominal pain has ceased, using Buzhong Yiqi Tang is undoubtedly correct. Regarding Wang Taipu's statement: "Treating lower jiao deficiencies requires urgent supplementation; slowness makes the path long and the force weak." If an urgent formula has thin flavor and aroma, its force is equivalent to a slow one. Therefore, treating postpartum conditions should follow Danxi's principle of consolidating the root, and the method of administration should emulate Taipu's advice to administer frequently. Those entrusted with life and death must surely focus on rescuing the critical condition.
