The Master said: When a woman has ceased menstruation and presents with a harmonious pulse, if the Yin pulse (the Chi position) is slightly smaller and weaker than the Yang pulse (the Cun position), this indicates that the fetal origin is consuming maternal Qi. The patient feels thirsty; this is not due to heat in the Upper Jiao, but rather Yin fire rushing upward. She cannot eat; this is not a disease of the Stomach, but nausea and food aversion caused by pregnancy obstruction (Morning Sickness). There are no chills or fever, indicating no exterior pathogenic factor. This condition is named Pregnancy. For all warming, cooling, tonifying, and purging agents, none are entirely suitable; one should primarily use Guizhi Tang (Cinnamon Twig Decoction). According to the method, around sixty days after conception (when the fetus is formed and its Qi affects the upper body), these symptoms should appear. If a physician, unaware of the pregnancy, mistakenly applies treatment causing adverse effects, and after another month, if the initial symptoms persist and vomiting or diarrhea are added, one must clearly inform the patient: do not repeat the error. The previous medication has caused suffering; now, stop all medication (as stated in the *I Ching*, "Do not use medicine, and there will be joy/improvement").
You Zaijing commented: A "Ping Mai" (Harmonious Pulse) means the pulse shows no signs of disease, consistent with the meaning in *Nei Jing* of "having bodily symptoms but no pathogenic pulse." The small and weak Yin pulse occurs because initially, fetal Qi is not yet vigorous, while Yin blood is being consumed; thus, the Yin pulse is smaller and weaker than the Yang pulse. By the third or fourth month, as menstrual blood accumulates for a long time, the Yin pulse becomes strong. As *Nei Jing* states, movement in the Hand-Shaoyin pulse indicates pregnancy; *Qian Jin Fang* mentions the rapid pulse at the Chi position in the third month, which refers to this. Thirst in pregnancy indicates internal heat. Some versions read "vomiting," which is also acceptable. Pregnant women in their second or third months often suffer from obstruction and inability to eat, which is exactly this situation. No chills or fever indicate no pathogenic factor. Since the pulse is normal yet there are bodily symptoms, and it is not due to cold-heat pathogens, no specific treatment is needed; only Guizhi Tang (Cinnamon Twig Decoction) should be used to harmonize Ying and Wei and regulate Yin and Yang. Xu Shi stated: Guizhi Tang (Cinnamon Twig Decoction), when used for exterior syndromes, releases the muscle layer and harmonizes Ying and Wei; when used for interior syndromes, it transforms Qi and regulates Yin and Yang. In early pregnancy, the upper and lower bodies are fundamentally healthy, but due to stagnation in the uterus, Qi overflows up and down. Therefore, using only Shaoyao (White Peony Root) to secure Yin Qi and prevent it from overflowing, combined with Guizhi (Cinnamon Twig), Gancao (Licorice), Shengjiang (Fresh Ginger), and Dazao (Jujube) to support Upper Jiao Yang and harmonize Stomach Qi, ensures that sufficient Yang Qi can resist invading Yin Qi. This does not directly treat a disease, but precisely treats the disease. Otherwise, treating thirst as Heat Evil and resolving it, or treating inability to eat as Spleen deficiency and drying it, would indeed be erroneous. The appearance of these symptoms at sixty days refers to the period of two months' gestation, which is the time of morning sickness. If treated blindly without knowing it is pregnancy, pathogenic Qi increases, Healthy Qi decreases, and vomiting and diarrhea worsen. "Jue Zhi" (Cut off/Stop) means to prohibit medical intervention. Lou Quanshan stated: I once treated a woman with morning sickness vomiting; previous doctors made her vomit more by treating her. Thinking of Zhang Zhongjing's principle of "Jue Zhi," I replaced tea with fried glutinous rice soup and stopped medication for over a month, after which she gradually stabilized. Another interpretation is that "Jue Zhi" means cutting off the root of the disease, not sticking to the theory of "An Tai" (Calming the Fetus), to avoid hesitation leading to error; this is also plausible.
When a woman's menstruation is incomplete during her period, or encounters cold air during intercourse, or is affected by the Six Evils (Pathogenic Factors) that interrupt the flow, residual blood remains, condenses into masses, and knots in the Bao Zhong (Uterus), named Zheng Bing (Mass Disease). If one already has Zheng Bing, or if the mass is not in the uterus, menstruation may continue until conception occurs; cessation of menstruation then indicates pregnancy. However, if less than three months have passed since cessation, yet continuous spotting occurs, and the fetus moves (if movement is below the umbilicus, the fetus is truly about to fall; if above the umbilicus), this is because the new blood gathering monthly is blocked from entering the uterus by the firmness of the Zheng Qi. The blood has nowhere to enter and leaks downward; this is actually not a problem with the fetus itself. Although there is a difference between pregnancy and Zheng Bing upon cessation of menstruation, to know the exact syndrome, one must look back from the current third month to the previous three months, totaling six months. If at six months of pregnancy there is fetal movement, and inquiry reveals that menstruation was regular and smooth for the previous three months without irregularity, then the cessation of menstruation can be confirmed as pregnancy. If the previous three months had irregular timing, then the current bleeding is due to accumulated blood from the last three months of amenorrhea (not the fetus). However, if there is a fetus, why is there still spotting? It is because the old blood has not been expelled, so new blood cannot enter the uterus to nourish the fetus and instead flows downward continuously. Therefore, the reason blood does not stop is that the Blood Stasis (Yu Xue) has not been removed. As long as the stasis remains, the fetus cannot be stable; one must purge the stasis, using Guizhi Fuling Wan (Cinnamon Twig and Poria Pill).
This section provides the formula and treatment for pregnancy complicated by pre-existing Zheng Bing.
Guizhi Fuling Wan Formula
Guizhi (Cinnamon Twig), Fuling (Poria), Danpi (Moutan Cortex), Taoren (Peach Seed, peeled and toasted), Shaoyao (White Peony Root) — equal parts.
Grind the five herbs into powder. Mix with refined honey to form pills the size of a rabbit pellet. Take one pill before meals daily. If ineffective, increase to three pills.
In women pregnant for six or seven months, the pulse is wiry (Xian) and there is fever (resembling an exterior syndrome), the abdomen distends further (without headache or body pain, but abdominal pain occurs; the back is not sensitive to cold, but the abdomen is, even feeling cold in the lower abdomen as if fanned by wind). The reason for this is that the Zi Zang (Substrate Organ/Uterus) is open (unable to close), allowing wind-cold Qi to invade. When the organ is open and wind enters, Yin prevails internally; thus, the wiry pulse indicates excess Yin, and the fever is due to Yang repulsion (False Heat). The abdominal distension is due to heat causing consumption and cold causing opening. One should use Fuzi Tang (Aconite Decoction) to warm the Zi Zang.
This section provides the formula and treatment for abdominal distension and lower abdomen feeling cold like being fanned.
Li Shi stated: Zi Zang refers to the Uterus. Guan Yuan (CV4) is three cun below the umbilicus; Bao Men (extra point) is two cun to the left; Zi Hu (extra point) is two cun to the right. Ancients said the Ming Men (Gate of Life) is where the woman's uterus is tied, but this does not mean Ming Men is the Zi Zang. *Jin Gui Yao Lue* clearly points to the lower abdomen; why do absurd commentators argue endlessly?
The Master said: Women may experience spotting (vaginal bleeding during pregnancy, commonly called Ji Jing). Or they may have a miscarriage (Ban Chan) at four or five months. After a miscarriage, damaging the Blood Sea, continuous bleeding persists without stopping. Also, there is bleeding during pregnancy (such as that caused by Zheng Bing mentioned earlier). Suppose a pregnant woman bleeds without Zheng Bing and only experiences abdominal pain; this is called Bao Zu (Womb Obstruction). Bao Zu means the Qi and Blood in the womb are disharmonious, obstructing gestation. Use Jiao Ai Tang (Collagen and Mugwort Decoction) as the primary treatment. (Extending this logic, for any woman with dripping menstruation or continuous bleeding before or after childbirth, it is due to deficiency of the Chong and Ren meridians and failure of Yin Qi to hold. This formula can tonify and secure them.)
This section provides the formula and treatment for Bao Zu. However, this formula is a general prescription for irregular menstruation and bleeding before and after childbirth/delivery.
Jiao Ai Tang Formula
Gan Dihuang (Prepared Rehmannia Root, 6 liang), Chuanxiong (Szechwan Lovage Rhizome), Ejiao (Donkey-hide Gelatin), Gancao (Licorice Root, each 2 liang), Aiye (Mugwort Leaf), Danggui (Angelica Sinensis, each 3 liang), Shaoyao (White Peony Root, 4 liang).
Decoct the seven herbs in 5 sheng of water and 3 sheng of clear wine to obtain 3 sheng of liquid. Strain. Add Ejiao and melt completely. Take 1 sheng warm, three times daily. If not improved, prepare again.
During pregnancy, if there is colicky abdominal pain, use Danggui Shaoyao San (Angelica and White Peony Powder) as the primary treatment.
This section provides the formula and treatment for colicky abdominal pain during pregnancy.
Xu Zhongke stated: Colicky pain here is a lingering, dull pain, unlike the cramping pain of Cold Hernia or the stabbing pain of Qi and Blood stagnation. It is due to insufficiency of Healthy Qi, allowing Yin to overcome Yang, Water Qi to overcome Earth, causing Spleen depression and frustration. The Earth Qi fails to regulate, resulting in lingering pain. Thus, Danggui and Shaoyao nourish Blood; Fuling and Baizhu support the Spleen; Zexie drains excess old water; Chuanxiong promotes the free flow of desired Qi and Blood. Huangqin (Scutellaria Root) is not used because the pain is due to deficiency and slight cold. However, hot herbs are not used either, as it is not severe cold; when Healthy Qi is sufficient, mild cold disappears naturally.
Danggui Shaoyao San Formula
Danggui (Angelica Sinensis), Chuanxiong (Szechwan Lovage Rhizome, each 3 liang), Shaoyao (White Peony Root, 1 jin), Fuling (Poria), Baizhu (Atractylodes Macrocephala Rhizome, each 4 liang), Zexiale (Alisma Rhizome, 0.5 jin).
Grind the six herbs into powder. Take one cun-bi (square-inch measure) mixed with wine, twice daily.
If there is incessant vomiting during pregnancy due to cold-fluid retention in the Stomach (indicating both cold and deficiency), use Ganjiang Renshen Banxia Wan (Dried Ginger, Ginseng, and Pinellia Pill) as the primary treatment.
This section provides the formula for incessant vomiting during pregnancy. Banxia (Pinellia Tuber) paired with Renshen (Ginseng) does not harm the fetus and can actually stabilize it.
Ganjiang Renshen Banxia Wan Formula
Ganjiang (Dried Ginger), Renshen (Ginseng, each 1 liang), Banxia (Pinellia Tuber, 2 liang).
Grind the three herbs into powder. Make pills using fresh ginger juice paste, sized like wu zi (walnut seeds). Take ten pills with warm water, three times daily.
If there is difficulty urinating during pregnancy, but diet remains normal, use Danggui Beimu Kushen Wan (Angelica, Fritillaria, and Sophora Pill) as the primary treatment.
You Zaijing commented: Difficulty urinating with normal diet indicates the disease does not originate from the Middle Jiao, and without symptoms like abdominal fullness or heaviness, it is certainly not fluid retention. It indicates Blood deficiency with Heat stagnation and scanty fluids. Danggui nourishes Blood; Kushen (Sophora Root) clears Heat; Beimu (Fritillaria Bulb) treats strangury and pathogenic Qi. Through the Lung's regulatory function acting on the Bladder, pathogenic Heat is cleared, and strangury resolves. This also clears the source of fluids.
Danggui Beimu Kushen Wan Formula
Danggui (Angelica Sinensis), Beimu (Fritillaria Bulb), Kushen (Sophora Root, each 4 liang).
Grind the three herbs into powder. Mix with refined honey to form pills the size of a mung bean. Take three pills with water, increasing to ten pills.
If there is "Water Qi" during pregnancy (meaning no visible swelling, only a sensation of water Qi): Internal Water Qi causes heaviness and difficult urination; External Water Qi causes aversion to cold (Shaxi). Water blocks the ascent of Yang Qi, causing dizziness upon rising. Use Kuizi Fuling San (Abelmosk Seed and Poria Powder) as the primary treatment (This focuses on unblocking orifices and promoting diuresis. Kuizi (Abelmosk Seed) can slip the fetus but is not contraindicated here because "where there is disease, the disease bears the burden").
This section provides the formula and treatment for Water Qi during pregnancy.
Kuizi Fuling San Formula
Kuizi (Abelmosk Seed, 1 sheng), Fuling (Poria, 3 liang).
Grind the two herbs into powder. Take one cun-bi with water, twice daily. Recovery occurs when urination becomes free.
For pregnant women without illness, medication is unnecessary. If the woman is thin and has heat, fearing that heat consumes Blood and harms the fetus, she should regularly take Danggui San (Angelica Powder) as the primary treatment.
Xu Zhongke stated: The element that generates life is Earth. What allows Earth to generate life is Dampness. Blood is transformed by Dampness, and the fetus relies on it especially. Thus, Danggui nourishes Blood; Shaoyao astringes Yin. The Liver governs Blood, so Chuanxiong is used to circulate Liver Qi. The Spleen governs Blood, so Baizhu strengthens Spleen Earth. Huangqin (Scutellaria Root) is used because the method for calming the fetus relies mainly on cooling Blood and promoting Qi flow. With Baizhu assisting Huangqin, Dampness does not stagnate due to Heat. Therefore, Baizhu assisting Huangqin has the ability to calm the fetus. The intent of this formula is to make Huangqin the sovereign herb. Difficulties in pregnancy and childbirth arise from Heat stagnation and dryness, causing mechanical dysfunction. Nourishing Blood and strengthening the Spleen, with Huangqin as the sovereign, prevents dryness and Heat. Hence, it is said that regular use facilitates easy delivery, keeps the fetus free from distress, and treats hundred diseases postpartum.
Danggui San Formula
Danggui (Angelica Sinensis), Huangqin (Scutellaria Root), Shaoyao (White Peony Root), Chuanxiong (Szechwan Lovage Rhizome, each 1 jin), Baizhu (Atractylodes Macrocephala Rhizome, 0.5 jin).
Grind the five herbs into powder. Take one cun-bi with wine, twice daily. Regular use during pregnancy facilitates easy delivery, keeps the fetus free from distress, and treats all postpartum diseases.
For obese, white-complexioned pregnant women with cold, warm herbs should be used to nourish the fetus; Baizhu San (Atractylodes Powder) is the primary treatment.
You Zaijing commented: Damage to the fetus in pregnancy can be due to Damp-Heat or Damp-Cold, varying according to the Yin-Yang of the person's Zang organs. Danggui San is the correct treatment for Damp-Heat. Baizhu San uses Baizhu and Muli (Oyster Shell) to dry Dampness, Chuanxiong to warm Blood, and Shuzhao (Sichuan Pepper) to remove Cold; thus, it is the correct treatment for Damp-Cold. Zhang Zhongjing listed them together to deeply instruct later generations.
Baizhu San Formula
Baizhu (Atractylodes Macrocephala Rhizome), Chuanxiong (Szechwan Lovage Rhizome), Shuzhao (Sichuan Pepper, processed to remove sweat), Muli (Oyster Shell).
Grind the four herbs into powder. Take one qian-bi with wine, three times daily, and once at night. If suffering from pain, add Shaoyao. If there is severe pain in the epigastrium, double the amount of Chuanxiong. If there is irritability, vomiting, pain, and inability to eat or drink, add Yixin (Asarum) 1 liang and large Banxia (Pinellia Tuber) 20 pieces. After taking the medicine, follow with vinegar-water. If vomiting occurs, take vinegar-water. If still unresolved, take wheat juice. If thirsty afterward, take barley porridge. Even if the disease is cured, do not discontinue the medicine.
If a woman injures the fetus, presenting with abdominal fullness during pregnancy, inability to urinate, heaviness from the waist down resembling water accumulation, at seven months of pregnancy, when the Taiyin (Lung) should nourish the fetus but fails to do so, this is due to Excess Heart Qi. One should needle and drain Laogong (PC8) and Guan Yuan (CV4). Recovery occurs when urination becomes slightly free.
You Zaijing commented: "Shang Tai" means the fetus is injured and diseased. Abdominal fullness, inability to urinate, and heaviness from the waist down resemble water accumulation but are not actually water. The reason is Excess Heart Qi. The Heart is Ministerial Fire, feared by the Lung. At seven months of pregnancy, the Lung should nourish the fetus. If Heart Qi is excessive, the Lung dares not descend, and the fetus loses its nourishment. This is what is meant by "Taiyin should nourish but does not." The Lung governs Qi transformation. If the Lung does not nourish the fetus, Qi transformation in the Bao Zhong is blocked, and water does not move. Abdominal fullness, difficult urination, and heaviness are due to this. One should not treat the Lung directly; instead, needle Laogong to drain Heart Qi and needle Guan Yuan to promote Kidney Qi, making urination slightly free. Then Heart Qi descends; once the Heart descends, the Lung functions automatically. Laogong is the Xi-Cleft point of the Heart meridian; Guan Yuan is the Front-Mu point of the Conception Vessel (associated with Kidney/Juan Yuan).
Xu Zhongke stated: In Zhang Zhongjing's chapter on pregnancy, there are ten formulas in total, seven being pills/powders and three being decoctions. Decoctions (Tang) are sweeping/cleansing. Since pregnancy requires calming the fetus, aggressive tonification or purgation is not suitable for sudden application; thus, slow action is taken. If the herbs are not extremely cold or hot, nor cloying/sticking to the chest, it is because urgent matters in calming the fetus involve nourishing Yin and regulating Qi.
