妇人甫产儿后，忽然眼目昏花，呕恶欲吐，中心无主，或神魂外越，恍若天上行云，人以为恶血冲心之患也，谁知
是气虚欲脱而然乎！盖新产之妇，血必尽倾，血室空虚，只存几微之气；倘其人阳气素虚，不能生血，心中之血，前已
荫胎，胎堕而心中之血亦随胎而俱堕，心无血养，所赖者几微之气以固之耳。今气又虚而欲脱，所剩残血，不能归经，
而成血晕之症矣。治法必须大补气血，断不可单治血晕也；或疑血晕是热血上冲，而更补其血。不愈助其上冲之势乎？
不知新血不生，旧血不散，补血以生新血，正活血以逐旧血也。然血有形之物，难以速生，气乃无形之物，易于迅发，
补气以生血，尤易于补血以生血耳。
方用补气解晕汤。
人参（一两） 生黄 （一两） 当归（一两，不酒洗） 黑芥穗（三钱） 姜炭（一钱）
水煎服。一剂而晕止。二剂而心定，三剂而血生，四剂而血旺，再不晕矣。此乃解晕之圣药，用参、 以补
气，使气壮而生血也；用当归以补血，使血旺而养气也。气血两旺，而心自定矣。用荆芥炭引血归经，用姜炭以行
瘀引阳，瘀血去而正血归，不必解晕而晕自解矣。一方之中，药只五味，而其奏功之奇而大如此，其神矣乎。
眉批∶原方极效，不可加减。
歌括∶妇人甫产儿初下，忽病血晕目昏花。
呕恶欲吐中无主，气虚将脱莫认差。
补气解晕用 参，黑荆姜炭当归身。
气血两旺心自定，四剂全愈免危困。
Immediately after childbirth, a woman suddenly experiences blurred vision, nausea with an urge to vomit, mental restlessness and lack of inner stability, or her spirit and soul seem to wander outward, feeling as if floating like clouds in the sky. People often attribute this to the affliction of "evil blood rushing to the heart" (E Xue Chong Xin), but little do they know that it is actually caused by Qi deficiency approaching collapse!
Generally, after recent childbirth, a woman's blood is inevitably largely depleted, leaving the Blood Chamber (Xue Shi) empty, with only a trace of Qi remaining; if the individual has inherently deficient Yang Qi, unable to generate blood, the blood within the Heart (Xin) that previously nourished the fetus, along with the fetus itself, is expelled upon delivery. With the Heart lacking blood nourishment, it relies solely on this faint Qi for consolidation. Now, since the Qi is also deficient and on the verge of collapse, the remaining residual blood cannot return to its vessels, resulting in the syndrome of Blood Fainting (Xue Yun). The treatment method must involve massive tonification of both Qi and Blood; one must absolutely not treat only the Blood Fainting. Some may suspect that Blood Fainting is caused by hot blood rushing upward, and thus attempt to further tonify blood, thereby inadvertently aiding the upward-rushing momentum. However, they fail to realize that without generating new blood, old blood will not disperse; tonifying blood to generate new blood is precisely the means to invigorate blood and expel old blood. Since blood is a tangible substance, it is difficult to generate rapidly, whereas Qi is intangible and easily stimulated swiftly. Therefore, tonifying Qi to generate blood is even more effective than directly tonifying blood to generate blood.
The formula used is Buqi Jun Tang (Qi-Tonifying Decoction for Resolving Fainting).
Ren Shen (Ginseng Radix et Rhizoma, 1 liang)
Sheng Huang Qi (Astragali Radix, 1 liang)
Dang Gui (Angelicae Sinensis Radix, 1 liang, not washed with wine)
Hei Jie Sui (Charred Schizonepetae Spica, 3 qian)
Jiang Tan (Charred Zingiberis Rhizoma, 1 qian)
Decoct in water and take orally. After one dose, the fainting ceases. After two doses, the mind settles. After three doses, blood is generated. After four doses, blood becomes abundant, and fainting does not recur. This is a sacred medicine for resolving fainting: Ren Shen and Huang Qi are used to tonify Qi, making Qi robust to generate blood; Dang Gui is used to tonify Blood, making Blood abundant to nourish Qi. When both Qi and Blood are abundant, the mind naturally settles. Charred Jing Jie (Schizonepetae Spica) is used to guide blood back into the vessels, and Jiang Tan is used to move stasis and guide Yang; once the stasis is removed, healthy blood returns to its course. Without specifically targeting the fainting, the symptom resolves itself. Within this single formula, there are only five herbs, yet their miraculous efficacy is so profound—how divine!
Marginal Note: The original formula is extremely effective and should not be modified.
Verse:
When a woman has just given birth,
Sudden blood fainting causes blurred vision.
Nausea and vomiting with mental unrest,
Do not mistake Qi deficiency nearing collapse.
Use Ren Shen in Buqi Jun Tang,
Along with Hei Jing Jie, Jiang Tan, and Dang Gui Shen.
When Qi and Blood are abundant, the mind settles naturally,
Four doses bring complete recovery, avoiding danger.
