单养贤曰∶丹溪先生云∶产后当大补气血为主，虽有他证，以末治之。恐人用消耗之剂，以虚其虚也。予见
世医，但知伤食当消，气满当顺，恶露当攻。罔顾产虚，遽下消耗。不知产妇服消耗药，胃气反伤，满闷益增，
气亦不降，郁积既久，遂成肿胀危证，
谁之咎哉？予于伤食气满证，微加消导于补中汤内，则脾强而所伤食气消散，助血行气，气行而恶露自行矣。又于
误用消食耗气下药，以致绝谷日久者，先用人参汤，送锅焦粉，引开胃口，以救绝谷，然后渐加补脾药，助以
消导。又于误用消耗等药成胀满者，仍用大补气血之剂，不致夭枉。后之学人，须遵丹溪方案，毋私心自用，以
夭人命也。
单养贤曰∶凡病起于气血之衰，脾胃之弱，至产后而虚又甚焉。故丹溪论产后当大补，已尽医产之旨。若能
扩充用药，治产可无过矣。产后气血暴虚，诸证乘虚易袭。如有气不行毋专耗气。有食不消，毋专消导。有
热不可用芩连，有寒不可用桂附。用寒凉则血块停滞，用辛热则新血崩流。至若虚中外感，见三阳表证，似可汗
也。在产后而用麻黄，虑有亡阳之误。见三阴里证，似可下也。在产后而用承气，恐致竭阴之患。耳聋胁痛，乃
肾虚恶露之停，休用柴胡。谵语汗出，乃元弱似邪之证，毋加宣导。厥由阳气之衰，难分寒热，非大补不能回阳
而起弱。痉因阴血之损，毋论刚柔，非滋阴不能活络而舒经。有如乍寒乍热，发作有期，证类疟疾，若以疟论，
病甚难痊。神不守舍，言语无伦，病似邪侵，如以邪论，危亡可待。去血多而大便燥结，苁蓉加于生地，莫投润
下之汤。汗出甚而小便短涩，六君倍用参 ，更加生津之剂。人参生化汤频灌，可救产后之虚危。长生活命丹屡
用，能苏绝谷之人。脱肛久泻，多是血虚下陷，补中益气正宜。口噤筋挛，乃因血燥类风，加人参、生地为最。
产户入风而痛甚，服宜羌活养荣方。玉门伤冷而不闭，先须床、菟、茱、硫。因气而满闷中虚，生化汤加木香为
佐。因食而嗳酸恶食，六君子加神曲为良。苏木、棱、蓬，大能破血。青皮、壳、实，最恶虚中。一切耗气破血
之剂，汗吐下之策，可施少壮之人，岂宜胎产之妇。
大抵新产之妇，先问恶露何如，块痛未除，不可遽加参术。腹疼若止，补中益气无疑。至若汗出亡阳，气虚喘促，
频用加参生化汤，固是从权。如因大热阴虚，血崩厥晕，速煎生化原方，乃为救急，言虽未能尽证，大略如斯而已。
慎斋按∶以上二条，序产后用药之失，而有误治之戒也。
Shan Yangxian said: Mr. Danxi once stated, "Postpartum treatment should primarily focus on greatly tonifying Qi and Blood (Qi Xue). Even if there are other symptoms, they should be treated as secondary concerns. This is to prevent people from using draining and damaging agents, which would further weaken an already deficient body." I have observed that contemporary physicians only know that food stagnation requires digestion-promoting methods, Qi stagnation and fullness require regulating Qi, and lochia stasis requires purging methods. They disregard the postpartum deficiency and hastily administer draining and damaging drugs. They do not realize that when postpartum women take such drugs, their Stomach Qi (Wei Qi) is damaged, leading to increased fullness and distension, failure of Qi to descend, and after prolonged accumulation, it results in critical swelling syndromes. Whose fault is this? When dealing with food stagnation and Qi stagnation fullness, I add a small amount of digestion-promoting herbs to Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). This strengthens the Spleen (Pi), allowing the damaged food and Qi to dissipate, assisting blood circulation and Qi movement; once Qi moves, lochia flows naturally. Furthermore, for those who have misused digestion-promoting and Qi-draining purgatives, resulting in long-term inability to eat, I first use Renshen Tang (Ginseng Decoction) to deliver Guojiao Fen (charred rice powder), to open the appetite and rescue the state of starvation. Then, I gradually add Spleen-tonifying herbs, assisted by digestion-promoting agents. For those who developed distension and fullness due to misusing draining drugs, I still use formulas that greatly tonify Qi and Blood, preventing premature death. Future students of medicine must follow Danxi's principles and must not act out of selfishness or self-will, thereby endangering lives.
Shan Yangxian said: All diseases originate from the decline of Qi and Blood and the weakness of the Spleen and Stomach; postpartum deficiency exacerbates this condition. Therefore, Danxi's discussion on greatly tonifying postpartum has fully captured the essence of treating postpartum conditions. If one can expand upon these medication principles, treating postpartum cases will be without error. Postpartum Qi and Blood are suddenly deficient, making various syndromes prone to invasion due to deficiency. If there is impaired Qi movement, do not exclusively use Qi-draining herbs; if there is undigested food, do not exclusively use digestion-promoting herbs; if there is heat, do not use Huangqin (Scutellariae Radix) and Lianzi (Coptidis Rhizoma); if there is cold, do not use Rougui (Cinnamomi Cortex) and Fuzi (Aconiti Lateralis Radix Praeparata). Using cold-cooling herbs causes blood clots to stagnate; using pungent-hot herbs causes fresh blood to hemorrhage. Regarding deficiency with external contraction, presenting with Taiyang (Greater Yang), Shaoyang (Lesser Yang), and Yangming (Bright Yang) exterior syndromes, sweating therapy might seem appropriate. However, using Mahuang (Ephedrae Herba) in postpartum cases risks Yang collapse (Wang Yang). Presenting with Jueyin (Terminal Yin), Shaoyin (Lesser Yin), and Taiyin (Greater Yin) interior syndromes, purging might seem appropriate. However, using Chengqi Tang (Major Order the Qi Decoction) in postpartum cases risks exhausting Yin (Jie Yin). Deafness and hypochondriac pain indicate Kidney (Shen) deficiency and lochia stasis; avoid using Chaihu (Bupleuri Radix). Delirium and sweating indicate Yuan Qi (Primal Qi) weakness resembling pathogenic invasion; do not add dispersing and guiding herbs. Jue syndrome (syncope/cold extremities) is caused by the decline of Yang Qi; it is difficult to distinguish between cold and heat, and only great tonification can restore Yang and revive the weak. Jing syndrome (spasm/stiffness) is due to Yin Blood loss; regardless of rigid or flaccid type, only Yin nourishment can unblock collaterals and relax meridians. If there are alternating chills and fever with periodic attacks, resembling malaria, treating it as malaria makes recovery difficult. If the Spirit (Shen) does not reside in its house, with incoherent speech, resembling pathogenic invasion, treating it as such leads to imminent danger. Excessive blood loss causing dry stool constipation: add Congrong (Cistanches Herba) to Shengdi Huang (Rehmanniae Radix); do not administer Runxia Tang (Moisten the Lower Decoction). Profuse sweating causing scanty and dysuric urine: increase the dosage of Renshen (Ginseng Radix et Rhizoma) in Liujunzi Tang (Six Gentlemen Decoction), and add fluids-generating agents. Frequently administering Renshen Shenghua Tang (Ginseng and Birth-Generating Decoction) can rescue postpartum Qi and Blood critical deficiency. Repeatedly using Changsheng Huoming Dan (Longevity and Life-Preserving Pill) can revive those who have stopped eating. Prolapsed rectum and chronic diarrhea are mostly due to Blood deficiency sinking; Buzhong Yiqi Tang is precisely indicated. Trismus and tendon spasms are due to Blood dryness resembling wind; adding Renshen and Shengdi Huang is best. Severe pain from wind entering the vagina: use Qianghuo Yangrong Fang (Notopterygium Nourishing the Young Formula). Cold injury to the vulva with failure to close: first use Chuanggen (Magnoliae Officinalis Cortex), Tusizi (Cuscutae Semen), Zhuyu (Corni Fructus), and Liuhuang (Sulfur). Fullness and middle-jiao deficiency due to Qi stagnation: add Muxiang (Aucklandiae Radix) to Shenghua Tang as an assistant herb. Belching sourness and aversion to food due to diet: Liujunzi Tang added with Shenqu (Massa Medicata Fermentata) is excellent. Sumu (Sappan Lignum), Sanleng (Sparganii Rhizoma), and Penglang (Curcumae Rhizoma) strongly break Blood stasis. Qingpi (Citri Reticulatae Pericarpium Viride), Qiaoke (Citri Reticulatae Pericarpium), and Shizhe (Aurantii Fructus Immaturus) are most detrimental in deficiency patterns. All agents that drain Qi and break Blood, as well as sweating, vomiting, and purging strategies, may be applied to robust individuals, but certainly not to pregnant or postpartum women.
Generally, for newly delivered women, first inquire about the lochia. If blood clots and pain remain, do not hastily add Renshen and Baizhu (Atractylodis Macrocephalae Rhizoma). If abdominal pain has ceased, using Buzhong Yiqi Tang is undoubtedly correct. As for sweating causing Yang collapse and Qi deficiency with panting, frequently using Jiashen Shenghua Tang (Ginseng-Augmented Birth-Generating Decoction) is indeed a provisional measure. However, if due to intense heat and Yin deficiency with hemorrhage and syncope, rapidly decocting the original Shenghua Tang is the emergency rescue method. Although words cannot cover all syndromes completely, the general principle is as described above.
Shenzhai commented: The above two sections outline errors in postpartum medication and provide warnings against mis-treatment.
