产后气血两虚，适宜采用温补法治疗。但对于刚生产完的产妇，如果恶露（产后排出的余血浊液）尚未下行，应当先使用疏导积滞的方法，以防止瘀血上冲。新产后的妇女容易感受风邪（中风），产后脾胃虚弱可能导致饮食停滞，产后大便干结多因血液阻滞所致，这三种情况属于实证，适宜采用清补兼施的方法。如果没有这三种证候，气虚的就补气，血虚的就补血，寒证的用温法，热证的用凉法，根据患者的具体情况灵活施治，这是产后调理的大原则。我曾经使用大剂量的人参、生姜、附子，来救治产后虚脱的危重证候；使用芍药来疏通因热燥而留滞的病邪，又何曾忌讳人参的补益作用、姜和附子的温热性质？而且芍药也并未表现出酸收敛邪的特性。
《阳明篇》说：伤寒病六七天，眼睛视物不清，眼球转动不灵活，没有明显的表证或里证，大便困难，身体微有发热，这属于实证，应当紧急攻下，宜用大承气汤。阳明病，发热且汗出多的，应当紧急攻下，宜用大承气汤。发汗后病不解，出现腹部胀满疼痛的，应当紧急攻下，宜用大承气汤。《少阴篇》说：少阴病，得病二三天，口干燥咽干的，应当紧急攻下，宜用大承气汤。少阴病，自利清水，颜色纯青，心下部必然疼痛，口干燥的，应当紧急攻下，宜用大承气汤。少阴病，六七天，腹部胀满，不大便的，应当紧急攻下，宜用大承气汤。寒邪伤害六经，只有阳明经和少阴经有急下证的，这是因为阳明经禀受悍烈热盛之气，少阴经有君火的变化。在阳明经如果燥热太甚，拖延则阴气就会枯竭；在少阴经如果火气猛烈，不加以遏制将会自我焚毁，这并不是肠胃中有实邪积满的情况。如果确实是肠胃中的实邪积满，即使十天不大便，患者也不会感到痛苦。像这六种证候，如果不能仔细审察清楚，不敢果断地急下，那么患这些病的人，很少能存活的。况且我常听人说：痞、满、燥、实、坚，五种证候都具备，然后才可以攻下。唉！需要急下的情况，完全不仅仅在于这五个字。
Postpartum Qi and Blood are both deficient, making warm tonification (Wen Bu) appropriate. However, for those who have just given birth, if lochia (postpartum discharge of blood and mucus) has not yet flowed, one should first employ methods to guide out stagnation, to prevent upward rushing of blood. New mothers are prone to wind-stroke (Zhong Feng), postpartum Spleen deficiency can lead to food retention, and postpartum dryness and constipation are often caused by blood obstruction; these three conditions constitute excess syndromes, suitable for a combination of clearing and tonifying. If none of these three syndromes are present, tonify Qi where Qi is deficient, nourish Blood where Blood is deficient, apply warmth to cold patterns, and apply cooling to heat patterns, acting according to what is beneficial for the patient; this is the general principle for postpartum treatment. I have once used large doses of Renshen (Ginseng Root), Shengjiang (Fresh Ginger Rhizome), and Fuzi (Prepared Aconite Lateral Root) to rescue critical cases of postpartum collapse; I have used Shaoyao (Peony Root) to benefit from resolving heat-dryness retention. How could I ever forbid the tonifying nature of Renshen or the hot nature of Shengjiang and Fuzi? Moreover, Shaoyao does not necessarily possess sour-astringent properties in this context.
The Yangming Chapter states: In Taiyang disease lasting six or seven days, if the eyes fail to see clearly and the pupils are unresponsive, without exterior or interior signs, with difficulty in defecation and slight fever, this is an excess syndrome; urgent purgation is required, using Dachengqi Tang (Major Order the Qi Decoction). In Yangming disease, if there is fever and profuse sweating, urgent purgation is required, using Dachengqi Tang. If after sweating the disease persists and abdominal fullness and pain occur, urgent purgation is required, using Dachengqi Tang. The Shaoyin Chapter states: In Shaoyin disease, if two or three days after onset, dry mouth and parched throat occur, urgent purgation is required, using Dachengqi Tang. In Shaoyin disease, if spontaneous diarrhea of clear water occurs, the color being purely green, with inevitable pain in the epigastrium and dry mouth, urgent purgation is required, using Dachengqi Tang. In Shaoyin disease, if six or seven days later, abdominal fullness and constipation occur, urgent purgation is required, using Dachengqi Tang. When cold pathogen injures the Six Channels, only Yangming and Shaoyin have urgent purgation indications. This is because Yangming possesses fierce and hot Qi, while Shaoyin undergoes transformation via Ministerial Fire. In Yangming, if dry-heat is excessive, delay will lead to the exhaustion of Yin Qi; in Shaoyin, if Fire Qi is fierce, failure to restrain it will lead to self-incineration. This is not due to solid accumulation in the intestines and stomach. If there were truly solid accumulation in the intestines and stomach, even if one did not defecate for ten days, there would be no distress. Regarding these six syndromes, if they are not thoroughly examined and one dares not perform urgent purgation, then few patients suffering from these conditions will survive. Furthermore, I have often heard it said that only when all five signs—Pi (Stifling Fullness), Man (Distension), Zao (Dryness), Shi (Solidity), and Jian (Hardness)—are present can purgation be administered. Alas! Cases requiring urgent purgation do not solely depend on these five characters.
