Fetal restlessness and insecurity during pregnancy arise from deficiency of the Chong and Ren meridians with insecure fetal qi, or damage due to excessive sexual activity and fatigue, or injury from lifting heavy objects and falling. It may also result from extreme emotions damaging blood vessels, or from taking hot-natured medicines that harm the fetal origin.
However, if the mother's illness causes fetal restlessness, treating the mother's disease will naturally stabilize the fetus; if a fetal pathology causes maternal discomfort, stabilizing the fetus will invariably cure the mother's condition. Furthermore, one should verify the prognosis by observing facial color and tongue appearance: red face and blue tongue indicate fetal death with maternal survival; blue face and red tongue indicate maternal death with fetal survival; both tongue and face being blue indicate death of both mother and fetus; both tongue and face being red indicate survival of both mother and fetus.
In cases of fetal restlessness, the pulse is necessarily rapid. In liver and spleen blood deficiency, the pulse is wiry and deficient. In fetal damage, the pulse is choppy. Upon trauma/blow, the pulse is tight.
Treatment should focus on clearing heat, nourishing blood, regulating qi, and calming the fetus. One should employ stillness to overcome movement, ensuring the spleen and kidney functions are complete and solid, so that the fetus naturally becomes tranquil.
The main prescription is An Tai San (Stabilize Fetus Powder) supplemented with Sheng Di Huang (Rehmanniae Radix), Bai Shao (Paeoniae Radix Alba), Mai Dong (Ophiopogonis Radix), and Mu Li (Ostreae Concha). For rebellious qi, add Zhi Ke (Aurantii Fructus); for sinking qi, add Chai Hu (Bupleuri Radix); for abdominal fullness, add Fu Pi (Moutan Cortex or Magnolia Bark); for qi deficiency, add Ren Shen (Ginseng Radix); for irritability and thirst, add Zhi Mu (Anemarrhenae Rhizoma); for tidal fever, add Shan Zhi Zi (Gardeniae Fructus). If there is dual deficiency of liver and spleen with accompanying heat, use Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder). If there is dual deficiency of Chong and Ren meridians with slight heat, use Sheng Shu Di Huang Wan (Raw and Prepared Rehmannia Pill). If there is dual deficiency of Chong and Ren meridians with severe heat, use Zhi Bai Si Wu Tang (Anemarrhena and Phellodendron Four Substances Decoction). If there is dual deficiency of Chong and Ren meridians with accompanying cold, use Jiao Ai Si Wu Tang (Donkey-hide Gelatin and Mugwort Four Substances Decoction).
An Tai San (Stabilize Fetus Powder)
Indicated for fetal restlessness with a slightly rapid pulse.
Tiao Qin (Scutellariae Radix) (1 liang 5 qian), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (1 liang 5 qian, stir-fried), Dang Gui (Angelicae Sinensis Radix) (2 liang), Gan Cao (Glycyrrhizae Radix et Rhizoma) (8 qian).
Processed into powder, decocted in water (5 qian dose), dregs removed, taken morning and evening until the fetus is stabilized.
During pregnancy, deficiency of the Chong and Ren meridians allows deficient fire to agitate the fetal origin, causing fetal restlessness; thus, this type of restlessness stems from deficient heat. Bai Zhu strengthens the spleen and generates blood; Dang Gui nourishes blood and enriches the fetus; Gan Cao clears fire and relieves urgency; Tiao Qin clears heat and calms the fetus. Taken as a powder decocted in water, this transforms heat and enriches blood, making the Chong and Ren meridians solid so the fetus receives nourishment. If the fetus is not insecure, how could there be fetal restlessness?
Sheng Shu Di Huang Wan (Raw and Prepared Rehmannia Pill)
Indicated for fetal restlessness with a deficient and rapid pulse.
Sheng Di Huang (Rehmanniae Radix) (5 liang), Shu Di Huang (Rehmanniae Radix Praeparata) (5 liang), Tian Dong (Asparagi Radix) (3 liang, heart removed), Mai Dong (Ophiopogonis Radix) (3 liang, heart removed), Dang Gui (Angelicae Sinensis Radix) (3 liang), Bai Shao (Paeoniae Radix Alba) (1 liang 5 qian, stir-fried), Fu Shen (Poria Cum Radix) (1 liang 5 qian, wood removed), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (1 liang 5 qian, stir-fried), Zhi Mu (Anemarrhenae Rhizoma) (1 liang 5 qian, stir-fried), Mu Li (Ostreae Concha) (3 liang, raw).
Processed into powder, bound with refined honey into pills, taken with rice drink (5 qian dose).
During pregnancy, dual deficiency of liver and kidney leads to insufficient yin blood. The Chong and Ren meridians are pressured internally by deficient heat, causing the fetus to lose nourishment, resulting in fetal restlessness; thus, this type of restlessness stems from blood deficiency with heat. Sheng Di Huang nourishes yin and strengthens water; Shu Di Huang tonifies blood and nourishes yin; Tian Dong clears the heart and moistens the lungs to benefit kidney water; Mai Dong moistens the lungs and clears the heart to generate fluids; Dang Gui nourishes blood and enriches the Chong vessel; Bai Shao astringes yin and secures the Ren vessel; Fu Shen leaches out dampness and calms the spirit; Bai Zhu strengthens the spleen and generates blood; Zhi Mu clears heat and moistens dryness to calm the fetus; Mu Li subdues heat and benefits yin to secure the fetus. Bound with honey and taken with rice drink, this fills the interior with yin blood so that deficient heat hides itself, making the Chong and Ren meridians solid. How could there be fetal restlessness?
Shi Sheng San (Ten Sages Powder)
Indicated for fetal restlessness with a deficient and soft pulse.
Shu Di Huang (Rehmanniae Radix Praeparata) (5 liang), Ren Shen (Ginseng Radix) (1 liang 5 qian), Huang Qi (Astragali Radix) (3 liang, honey-fried), Bai Zhu (Atractylodis Macrocephalae Rhizoma) (1 liang 5 qian, stir-fried), Dang Gui (Angelicae Sinensis Radix) (3 liang), Bai Shao (Paeoniae Radix Alba) (1 liang 5 qian, wine-fried), Chuan Xiong (Ligustici Chuanxiong Rhizoma) (1 liang), Xu Duan (Dipsaci Radix) (3 liang), Gan Cao (Glycyrrhizae Radix et Rhizoma) (5 qian, roasted), Sha Ren (Amomi Fructus Rotundus) (1 liang, stir-fried).
Processed into powder, decocted in water (5 qian dose), dregs removed, taken orally.
During pregnancy, severe deficiency of qi and blood fails to nourish and enrich the fetal breath, causing fetal restlessness; thus, this type of restlessness stems from severe qi and blood deficiency. Ren Shen supports the primal qi and tonifies qi; Huang Qi tonifies qi and consolidates the middle; Shu Di Huang tonifies blood to nourish the Chong and Ren meridians; Bai Zhu strengthens the spleen to generate qi and blood; Dang Gui nourishes blood and enriches the meridians; Bai Shao astringes yin and calms the fetal breath; Chuan Xiong regulates the Blood Sea; Xu Duan connects sinews and meridians; Roasted Gan Cao moderates the middle and benefits the stomach; Sha Ren awakens the spleen and opens the appetite. Taken as a powder decocted in water, this harmonizes the spleen and stomach so that qi and blood fill the interior and the fetus receives nourishment. If the fetus is not tranquil, what is there to worry about?
