Treatment for the period from three to nine months of pregnancy is called Ezu (Morning Sickness / Pregnancy Nausea). The patient experiences mental restlessness and oppression, heaviness of the head, dizziness and blurred vision, heaviness and weakness in the four limbs, lethargy and lack of desire to move; when heat arises, there is aversion to the smell of food, a craving for salty and sour flavors, excessive sleep with little rising, vomiting and inability to eat. Or there may be restless fetus, abnormal fetal movement, pain in the waist and abdomen; or vaginal bleeding at inappropriate times, as well as all diseases during pregnancy, are all treated by this prescription.

Gancao (Licorice Root), Fuling (Poria), Danggui (Angelica Sinensis), Shudihuang (Prepared Rehmannia Root), Chuanxiong (Sichuan Lovage Rhizome), Baizhu (Atractylodes Macrocephala Rhizome), Huang [Note: Text implies Huangqi or Huangqin, kept as original], Shaoyao (White Peony Root), Banxia (Pinellia Tuber - processed, washed seven times, sliced, stir-fried), Ejiao (Donkey-hide Gelatin - sliced, stir-fried with rice flour), Diyü (Sanguisorba Root) (all in equal proportions).

Crush the above herbs into coarse powder. Take 3 qian per dose, add 1.5 cups of water and 4 slices of fresh ginger, decoct until reduced to 0.8 cup, strain, and take warm at any time. Another version excludes Banxia and Diyü, but includes Renshen (Ginseng) and Sangjisheng (Taxillus Branches). Another version excludes Baizhu, Huang, Banxia, and Diyü, but adds Aye (Mugwort Leaf). This is essentially Jiao'ai Tang (Gelatin and Mugwort Decoction) added with Fuling (Poria).

Water and fluids stagnate and accumulate, condensing into Phlegm (Tan), which everyone possesses. When scant, it causes no harm; when abundant, it becomes pathological, obstructing digestion and leading to vomiting and reflux. In pregnancy, if vomiting and reflux are severe, it damages the fetus. The origin of these ailments lies in disharmony of Stomach Qi or invasion by Wind-Cold. Cold combats within the Stomach, thus forming this disease. This is also one aspect of Ezu.

For treating pregnancy Ezu, characterized by mental restlessness and oppression, deficiency-heat irritability and vomiting, dizziness and blurred vision, lethargy and drooping of the four limbs, general joint pain, phlegm-induced vomiting, aversion to food smells, preference for salty and sour foods, aversion to cold with sweating, extreme emaciation and sallow complexion, excessive lying down with little rising, and refusal to eat: If a pregnant woman has Phlegm, it inevitably causes obstruction diseases. *Qianjin Fang* uses Banxia Fuling Tang (Pinellia and Poria Decoction) to address this, demonstrating the brilliance of Sun Simiao's prescriptions. If the pregnant woman is weak and the fetus is unstable, fetal movement will certainly lead to adverse outcomes. It entirely depends on the physician to assess the patient's strength and weakness before prescribing, so what is there to worry about?

Banxia (Pinellia Tuber - 1 liang, processed ten times, separately sliced, stir-fried until yellow), Shengjiang (Fresh Ginger - 5 liang), Fuling (Poria), Shudihuang (Prepared Rehmannia Root) (each 3 liang), Juhong (Citrus Reticulata Pericarpium), Beixixin (Asari Radix et Rhizoma), Renshen (Ginseng), Shaoyao (Peony Root), Zisu (Perilla Leaf), Chuanxiong (Ligusticum Chuanxiong Rhizome) (each 1 liang), Kugen (Platycodon Root), Gancao (Licorice Root) (each 0.5 liang).

Crush the above herbs into coarse powder. Take 4 qian per dose, add 2 cups of water and 7 slices of ginger, decoct until reduced to 0.7 cup, strain, and take warm on an empty stomach. Also take Fuling Wan (Poria Pill). The *Ju Fang* and Cui Shi's versions exclude Zisu and Xixin, but include Xuanfuhua (Inula Flower, 1 liang). If there is exogenous heat causing irritability and thirst, or mouth ulcers, remove Juhong and Xixin, and add Qianhu (Peucedanum Root) and Zhimu (Anemarrhena Rhizome), each 3 liang. For cold abdomen with diarrhea, remove Shudihuang and add Chao Guixin (Stir-fried Cinnamon Twig), 2 liang. For deficiency-heat in the Stomach with constipation and dark, scanty urine, add Dahuang (Rhubarb Root), 3 liang, remove Shudihuang, and add Huangqin (Scutellaria Root), 1 liang. Although Banxia may disturb the fetus, if stir-fried properly, it poses no harm.
