妊娠忽然下血，其证有四∶或因火热，迫血则妄行；或因郁怒，气逆则动血；或因损触胎气，胞宫受伤
而下血；或因脾肾气陷，命门不固而脱血。凡此皆动血之最者也。不速为调理，则必致堕胎矣。然治此者，
必先察其血去之多少，及于血去之后，尤当察其邪之微甚，如火犹未清，仍当清火，气犹未顺，仍当顺气。
若因邪而动血，血去而营虚，则速当专顾元气，以防脱陷。此中或当治标，或当救本，或当兼标本而调理
之。倘不知先后缓急，将恐治标未已而救本无暇也，当详察之。
若火盛迫血妄行者，当察其火之微甚。火之微者，凉胎饮；稍甚者，徙薪饮；再甚者，保阴煎、子芩散。
若肝经有风热而血下者，宜防风黄芩丸。若怒气伤肝，气逆血动而暴至者，宜保阴煎；若气有未顺而胀满者，
四七汤、二陈汤，或加芎、归之类；若兼肝火者，宜化肝煎。

治。若血已离位，蓄积胞宫，为胀为痛，而余血未出者，欲与留之有不可得，欲去其血而不伤营气，则惟四

The An Tai Ji Sheng Tang (Cuscuta and Taxillus Decoction for Calming the Fetus, see "Ancient Formulas of Fu Ren Gui" in Liang Fang) is used to treat vaginal bleeding during pregnancy, or fetal restlessness, or pain in the lower back and abdomen.
Sang Ji Sheng (Taxilli Caulis), Bai Zhu (Atractylodis Rhizoma), Fu Ling (Poria) (each 5 fen), Gan Cao (Glycyrrhizae Radix et Rhizoma) (1 qian).
Take the above herbs, decoct with water, and take orally.
Dang Gui Shao Yao Tang (Angelica Sinensis and Paeonia Decoction, see "Ancient Formulas of Fu Ren Gui") is used to treat acute pain in the heart and abdomen during pregnancy, or dizziness caused by excessive blood loss.
Dang Gui (Angelicae Sinensis Radix), Chao Bai Shao Yao (Fried Paeoniae Radix Alba), Chao Bai Zhu (Fried Atractylodis Rhizoma), Fu Ling (Poria), Ze Xie (Alismatis Rhizoma) (each 1 qian), Chuan Xiong (Ligustici Chuanxiong Rhizoma) (2 qian).
Take the above herbs, decoct with water, and take orally.
Sudden vaginal bleeding during pregnancy has four types of syndromes: one is due to fire-heat forcing blood to move recklessly; another is due to depression and anger causing qi rebellion and disturbing blood; a third is due to physical trauma damaging the fetal qi and injuring the uterus, leading to bleeding; and the fourth is due to sinking of spleen and kidney qi, with failure of the Gate of Vitality (Ming Men) to consolidate, resulting in hemorrhage. All these are the most severe causes of disturbing blood. If not regulated promptly, abortion will inevitably occur. However, when treating this condition, one must first observe the amount of blood lost, and especially after the bleeding, observe the severity of the pathogenic factors. If fire-heat has not been cleared, it should still be cleared; if qi is not yet smooth, it should still be regulated. If bleeding was caused by pathogens, and after blood loss the nutritive qi (Ying Qi) is deficient, one must quickly focus on protecting the original qi (Yuan Qi) to prevent collapse. In this context, some cases require treating the branch (symptoms), some require saving the root (constitution), and some require addressing both simultaneously. If the sequence and urgency of treatment are not understood, there is a fear that while treating the branch, there will be no time left to save the root; therefore, careful observation is essential.
If flourishing fire forces blood to move recklessly, one must observe the severity of the fire. For mild fire, use Liang Tai Yin (Cool the Fetus Decoction); for slightly more severe cases, use Xi Xin Yin (Remove Firewood Decoction); for even more severe cases, use Bao Yin Jian (Preserve Yin Decoction) or Zi Qin San (Zi Qin Powder). If wind-heat in the Liver channel causes bleeding, use Fang Feng Huang Qin Wan (Saposhnikovia and Scutellaria Pills). If anger injures the Liver, causing qi rebellion and sudden blood disturbance, use Bao Yin Jian (Preserve Yin Decoction); if qi is not yet smooth and accompanied by distension, use Si Qi Tang (Four Seven Decoction) or Er Chen Tang (Two Aged Herbs Decoction), possibly adding Chuan Xiong (Ligustici Chuanxiong Rhizoma) and Dang Gui (Angelicae Sinensis Radix); if accompanied by Liver fire, use Hua Gan Jian (Transform Liver Decoction).

If touching or trauma damages the fetal qi and injures the uterus causing bleeding, use An Tai San (Calming the Fetus Powder) or Jiao Ai Tang (Colla Corii Asini and Artemisia Decoction); if blood loss is significant, double the dosage of Ren Shen (Ginseng Radix et Rhizoma). If falling from a height damages the fetal qi and causes bleeding, use Yi Mu Di Huang Tang (Motherwort and Rehmannia Decoction) or An Tai San (Calming the Fetus Powder); if caused by fright leading to qi deficiency and sinking, add Ren Shen (Ginseng Radix et Rhizoma).

If the Spleen and Stomach have always been weak, or if bleeding occurs occasionally due to Spleen injury, use Shou Pi Jian (Nourish Spleen Decoction) or Gui Pi Tang (Restore the Spleen Decoction); if Middle Qi is sinking, use Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction). If blood deficiency with slight heat causes dripping blood or hematuria, use Xu Duan Tang (Dipsacus Decoction).

For the above various conditions of disturbing blood, if the blood loss is not heavy, there is no accumulation of blood, the fetus is not yet damaged but bleeding persists, clear if necessary, tonify if necessary, but primarily focus on calming and consolidating the fetus. If blood has already left its vessels, accumulated in the uterus, causing distension and pain, and residual blood remains unexpelled, retaining it is impossible, and expelling it without damaging Ying Qi (Nutritive Qi) is difficult; thus, using Si Wu Tang (Four Substances Decoction) with a significantly increased dose of Dang Gui (Angelicae Sinensis Radix) is most appropriate. If observation shows that fetal qi is disturbed and retention is difficult, then Wu Wu Jian (Five Items Decoction) and Jue Jin Jian (Cross River Decoction) are crucial medicines.

Another formula: Treats fetal movement caused by sudden falls. Use 2 qian of Chuan Xiong (Ligustici Chuanxiong Rhizoma) powder, taken with wine. If the fetus is alive, it calms the fetus; if dead, it expels it.
Another formula: Treats the same condition. Use Sha Ren (Amomi Fructus) fried with peel into powder, take 2 qian each time, administered with rice water. The abdomen feeling warm indicates the fetus is calmed.
