分娩之后，眼前出现黑花飞舞，头晕目眩甚至昏厥，意识丧失，这种情况被称为“血晕”。其病因主要有三种：一是因过度劳累导致气竭神昏；二是因大量失血导致气绝晕厥；三是因痰火乘虚上扰，致使神志不清。这三种情况，都是神魂不能随心神正常往来，生命机能几乎停止的状态。
如果医生偏信古方，将这种晕厥误认为是恶血冲心，而轻易使用破血散瘀的药物；或者片面地认为是痰火所致，而不进行补益，专门使用消降痰火的方剂，这都是会害人性命的错误做法。
应当立即服用大剂量的生化汤，先消除血块、缓解疼痛。如果是确实因为面色苍白等气血脱失症状，或者出汗过多导致的晕厥，都应立即服用一帖生化汤，随后加入人参二三钱。如果是因过度劳累导致的晕厥，以及血崩气脱导致的晕厥，连续灌服两帖后，再加入人参二三钱。绝对不可以怀疑人参是补药而延迟使用。
如果确实是痰火乘虚上扰导致的晕厥，可以在生化汤中加入橘红四分。如果身体极度虚弱，也应加入人参。如果是肥胖且多痰的人，再加竹沥七分和少许生姜汁。以上三种类型的晕症，都不可使用破血类的方剂。如果血块疼痛剧烈，可将药物煎好后送服益母丸，或鹿角灰，或元胡散，或独圣散（注：原文“独”后似缺字，结合语境及常见产后方，此处保留原文“独”字或指代单一强力止痛方，但根据常规理解多为“独圣散”或类似，此处严格依原文“独”字处理，意指单味或单方）。
川芎、当归（各四钱），姜炭、炙甘草（各四分），桃仁（十粒），人参（三钱），荆芥（四分），大枣（一枚），煎汤服用。如果是脉象微弱、形体脱失接近衰竭的症状，可以加入人参（三四钱）频繁灌服以急救。出汗多的情况也是如此。如果没有出汗且没有脱证表现，只服用大剂量生化汤即可，不必加入人参。如果左手足脉搏消失，也属于危重病症，必须加入人参。如果血块疼痛剧烈，加入肉桂（七分）；口渴加入麦冬（一钱）、五味子（十粒）；出汗多加入麻黄根（一钱）。如果血块不痛，可配合使用人参等补气药。
凡是治疗产后各种危急重症，必须在一日一夜内频繁服用三四帖药，才能挽救危局转危为安。否则如果像平常一样服药，就来不及救治了。
After childbirth, seeing black spots before the eyes, dizziness, fainting, and loss of consciousness is called "Blood Fainting" (Xue Yun). There are three causes: first, exhaustion from overwork leading to Qi depletion and spirit confusion; second, massive blood loss leading to Qi collapse and syncope; third, Phlegm-Fire taking advantage of deficiency to rise upward, causing unclear spirit. These three conditions all represent a state where the Hun (Ethereal Soul) does not follow the Shen (Spirit), and vital functions are nearly ceased.
If physicians blindly trust ancient formulas, mistaking this fainting for "Evil Blood Snatching the Heart," and lightly administer blood-dispersing agents; or if they片面ly attribute it to Phlegm-Fire, neglecting tonification, and exclusively using methods to eliminate and descend phlegm-fire, these are errors that cost lives.
One should urgently administer a large dose of Shenghua Tang (Transform the Stasis Decoction) to first resolve stasis and relieve pain. If it is truly a case of physical collapse manifested by pallor, or fainting due to excessive sweating, one should urgently administer one dose of Shenghua Tang, followed immediately by adding 2-3 qian of Renshen (Ginseng Radix et Rhizoma). If it is fainting due to severe overwork, or fainting due to metrorrhagia and Qi collapse, continue administering two doses consecutively, then add 2-3 qian of Renshen. One must absolutely not hesitate to use Renshen because it is considered a tonic.
If it is truly fainting caused by Phlegm-Fire rising due to deficiency, add Ju Hong (Citri Reticulatae Pericarpium Rubrum) 4 fen to Shenghua Tang. If the deficiency is severe, also add Renshen. If the patient is obese and prone to phlegm, additionally add Zhu Li (Bambusae Succus) 7 fen and a small amount of Sheng Jiang Zhi (Zingiberis Rhizoma Recens Expressum). For the above three types of fainting, blood-breaking formulas must not be used. If the pain from stasis is severe, administer Yi Mu Wan (Motherwort Pill), Lu Jiao Hui (Cornu Cervi Degelatinatum Ash), Yuan Hu San (Corydalis Powder), or Du [San] (Single Herb Powder) with the decoction.
For postpartum fainting due to physical collapse or excessive sweating:
Chuan Xiong (Ligustici Chuanxiong Rhizoma) and Dang Gui (Angelicae Sinensis Radix) (each 4 qian), Jiang Tan (Zingiberis Rhizoma Carbonisatum) and Zhi Gan Cao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle) (each 4 fen), Tao Ren (Persicae Semen) (10 grains), Renshen (Ginseng Radix et Rhizoma) (3 qian), Jing Jie (Schizonepetae Spica) (4 fen), and Zao (Jujubae Fructus) (1 date). Decoct and take orally. In cases of pulse collapse and physical collapse nearing extinction, add Renshen (3-4 qian) and administer frequently for rescue. The same applies to excessive sweating. If there is no sweating and no signs of collapse, only administer a large dose of Shenghua Tang without adding Renshen. If the pulse on the left hand and foot disappears, this is also a critical condition requiring the addition of Renshen. If stasis pain is severe, add Rou Gui (Cinnamomi Cortex) (7 fen); if thirsty, add Mai Dong (Ophiopogonis Radix) (1 qian) and Wu Wei Zi (Schisandrae Chinensis Fructus) (10 grains); if sweating is excessive, add Ma Huang Gen (Ephedrae Radix et Rhizoma) (1 qian). If there is no stasis pain, Renshen can be used in conjunction.
In treating any critical postpartum conditions, medicines must be administered frequently, 3-4 doses within a day and night, to turn danger into safety. Otherwise, if treated normally, it will be too late.
