妊妇有失足跌损，致伤胎元，腹中疼痛，势如将堕者，人只知是外伤之为病也，谁知有内伤之故乎！凡人内
无他症，胎元坚固。即或跌扑闪挫，依然无恙。惟内之气血素亏，故略有闪挫，胎便不安。若只作闪挫外伤治，断
难奏功，且恐有因治而反堕者，可不慎与！必须大补气血，而少加以行瘀之品，则瘀散胎安矣。但大补气血之
中，又宜补血之品多于补气之药，则无不得之。
方用救损安胎汤。
当归（一两，酒洗） 白芍（三钱，酒炒） 生地（一两，酒炒） 白术（五钱，土炒） 炙草（一钱） 人参（一
钱） 苏木（三钱，捣碎） 乳香（一钱，去油） 没药（一钱，去油）
水煎服。一剂而疼痛止，二剂而势不下坠矣，不必三剂也，此方之妙，妙在既能去瘀而不伤胎，又能补气补
血，而不凝滞，固无通利之害，亦痊跌闪之伤，有益无损，大建奇功，即此方与。然不特治怀孕之闪挫也，即无
娠闪挫，亦可用之。
眉批∶即用寻常白术，土炒焦最妙，以其能理气行血也。于白术味过甘，不能理气行血，用者知之。
歌括∶妊娠跌损伤胎元，腹痛如堕宜救援。
外伤为病内伤故，气血素亏是病源。
救损安胎归芍吞，生地白术炙草参。
苏木乳香与没药，瘀散胎安病除根。
If a pregnant woman falls and suffers trauma, damaging the fetal foundation (Tai Yuan), causing abdominal pain and a sensation of impending miscarriage, people only know this is a disease caused by external injury, but who would suspect an internal cause? Generally, if there are no other internal symptoms and the fetal foundation is solid, even if one suffers a fall or sprain, one remains unharmed. Only when the internal Qi and Blood are inherently deficient will even a slight sprain cause the fetus to become unstable. If treated merely as an external sprain injury, it is unlikely to succeed, and there is even a risk that treatment might induce miscarriage; can one not be cautious? One must greatly tonify Qi and Blood, while adding a small amount of blood-invigorating substances, so that the blood stasis dissipates and the fetus becomes secure. However, within the great tonification of Qi and Blood, the blood-nourishing herbs should outweigh the Qi-tonifying ones, thereby ensuring success.
The prescription used is Jiu Sun An Tai Tang (Rescue Trauma and Calm Fetus Decoction).
Dang Gui (Radix Angelicae Sinensis) - 1 liang, washed with wine; Bai Shao (Radix Paeoniae Alba) - 3 qian, stir-fried with wine; Sheng Di Huang (Radix Rehmanniae Preparata) - 1 liang, stir-fried with wine; Bai Zhu (Rhizoma Atractylodis Macrocephalae) - 5 qian, stir-fried with earth; Zhi Gan Cao (Radix Glycyrrhizae Preparata) - 1 qian; Ren Shen (Radix Ginseng) - 1 qian; Su Mu (Santalum Rubrum) - 3 qian, crushed; Ru Xiang (Olibanum) - 1 qian, oil removed; Mo Yao (Myrrha) - 1 qian, oil removed.
Decoct in water and take orally. After one dose, the pain stops; after two doses, the sensation of bearing down disappears; three doses are unnecessary. The brilliance of this formula lies in its ability to dispel blood stasis without harming the fetus, and to tonify Qi and Blood without causing stagnation. It indeed avoids the harm of purgative/diuretic actions, yet cures the injuries of falls and sprains. It is beneficial without detriment, achieving remarkable results. This is the formula. Moreover, it is not only suitable for sprains during pregnancy, but also for sprains in non-pregnant women.
Marginal Note: Using ordinary Bai Zhu (Rhizoma Atractylodis Macrocephalae), stir-fried with earth until scorched, is best, because it can regulate Qi and move Blood. If the Bai Zhu tastes overly sweet, it cannot regulate Qi and move Blood; users should be aware of this.
Song Verse:
Pregnancy trauma damages the fetal foundation,
Abdominal pain like miscarriage requires rescue.
External injury manifests from internal causes,
Inherent deficiency of Qi and Blood is the source.
Jiu Sun An Tai Tang swallows Dang Gui and Bai Shao,
Sheng Di, Bai Zhu, Zhi Gan Cao, and Ren Shen follow.
Su Mu, Ru Xiang, and Mo Yao combined,
Stasis disperses, fetus calms, disease root eradicated.
