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.
