求嗣全书载赶经调和诀云∶有一等女人，月经来时，专在下弦之期，必用养血之法
以逐之。视其色紫，则知血热，服凉血药以缓其气，则气血和而来迟，渐渐赶之，定到初头
；视其色淡短少者，则服养血和血药，养其命门，亦赶到初头。察女人肥瘦强弱而用药，一
月便不能合，赶之之久，定到上弦，此赶经之法也（经有不可赶者，谓女人之经，有一年一度行者，有四季行者），以

人上弦交，多生男耳。又有一等女
人身体肥胖，子宫脂膜长满，经水虽调，亦令无子，须服开子宫之药，以消其脂膜。
袁先生云∶巢氏论妇人妊娠，一月名胎胚，足厥阴脉养之；二月名始膏，足少阳脉养之
；三月名始胎，手少阴脉养之；四月始受水精以行血脉，手少阳脉养之；五月始受火精以成
其气，足太阴脉养之；六月始受金精以成其筋，足阳明脉养之；七月始受木精以成其骨，手
太阴脉养之；八月始受土精以成肤革，手阳明脉养之；九月始受石精以成毛发，足少阴脉养
之；十月脏腑关节人神俱备，足太阳脉养之，此其大略也（胚胎兆于一气，胚者气之形，膏者气之凝，胎者形之着。先
天以制生化，故以水火金木土石制而化焉；后天顺序而成，故以木火土金水相生，而养以逆，而化以顺，而成自然之妙
也）。若求其细，则受胎在腹，七日一
变，展转相成，各有相生，《大集经》备矣。今妇人堕胎，在三月五月七月者多，在二四六
月者少，脏阴而腑阳，三月属心，五月属脾，七月属肺，皆在五脏之脉，阴常易亏，故多堕
耳。如昔曾三月堕胎，则心脉受伤，先须调心，不然至三月复堕。昔曾五月堕胎，则脾脉受
伤，先宜治脾，不然至五月复堕。惟有一月之内堕胎，则人皆不知有胎，但知不受妊，不知
其受而堕也。一月属肝，怒则堕，多洗下体则窍开亦堕。一次既堕，则肝脉受伤，他次亦堕
。今之无子者，大半是一月堕胎，非尽不受妊也。故凡初交之后，最宜将息，勿复交接，以
扰其子宫，勿令怒，勿令劳，勿令举重，勿令洗浴，而又多服养肝平气之药，胎可固矣。
《求嗣全书》记载的“赶经调和诀”中说：有一类女性，月经来潮时总是在农历每月的下弦月时期（约农历二十二日至二十四日），必须采用养血的方法将其提前。如果观察经血颜色紫暗，就知道是血热，服用凉血药物以缓和气血，使气血调和而月经周期逐渐推迟，慢慢调整，最终定能回到月初（上弦之前）；如果观察经血颜色淡、量少，就服用养血和血的药物，滋养命门，也能将月经周期调整到月初。根据女性的胖瘦强弱来用药，一个月可能无法完全合拍，经过长时间的追赶调整，最终定能到达上弦月时期（约农历初七至初八），这就是赶经的方法。（有些经期的情况是无法强行调整的，比如有的女性一年只来一次月经，有的女性四季都来月经）。如果在农历上弦月期间同房，多生男孩。又有一类女性身体肥胖，子宫内脂膜过厚，虽然月经调顺，也会导致不孕，需要服用开通子宫的药物，以消除其脂膜。
袁先生说：巢元方论述妇人妊娠，第一个月名为胎胚，由足厥阴肝经滋养；第二个月名为始膏，由足少阳胆经滋养；第三个月名为始胎，由手少阴心经滋养；第四个月开始接受水精以运行血脉，由手少阳三焦经滋养；第五个月开始接受火精以形成气，由足太阴脾经滋养；第六个月开始接受金精以形成筋，由足阳明胃经滋养；第七个月开始接受木精以形成骨，由手太阴肺经滋养；第八个月开始接受土精以形成皮肤肌肉，由手阳明大肠经滋养；第九个月开始接受石精以形成毛发，由足少阴肾经滋养；第十个月脏腑关节及人体神气全部具备，由足太阳膀胱经滋养，这是大概的情况。（胚胎在气化之初就已显现，胚是气的形态，膏是气的凝聚，胎是形的附着。先天之气制约生化过程，所以用水、火、金、木、土、石来制约并转化它；后天依序而成，所以按木、火、土、金、水的相生顺序，以逆的方式养育，以顺的方式转化，从而成就自然的妙用。）如果要探究细节，受孕在腹中后，每七天发生一次变化，辗转相成，各有相生关系，《大集经》中有详细记载。现在妇女流产，多在第三、五、七个月，在第二、四、六个月的较少。脏属阴，腑属阳，第三个月属心，第五个月属脾，第七个月属肺，都在五脏的经脉上，阴气容易亏损，所以容易流产。如果以前曾在第三个月流产，说明心脉受伤，必须先调理心脏，否则到了第三个月会再次流产。如果以前曾在第五个月流产，说明脾脉受伤，必须先治疗脾脏，否则到了第五个月会再次流产。只有在一个月内流产的，人们都不知道已经怀孕，只知道没有受孕，不知道是受孕后流产了。第一个月属肝，发怒会导致流产，经常清洗下身导致窍孔张开也会流产。一旦有一次流产，肝脉就会受伤，下次也会流产。现在的不孕症患者，大半是因为在一个月内流产，并非完全不能受孕。所以凡是初次同房之后，最宜静养休息，不要再行房事，以免扰动子宫，不要发怒，不要劳累，不要举重物，不要洗浴，并且多服用养肝平气的药物，胎儿就可以稳固了。
The *Qiusi Quanshu* (Complete Book for Seeking Heirs) records the "Regulation of Menstruation and Harmonization Formula" stating: There is a category of women whose menstruation occurs specifically during the waning moon phase (approximately the 22nd to 24th day of the lunar month). It is necessary to employ blood-nourishing methods to advance the cycle. If the menstrual blood appears dark purple, it indicates Blood Heat (Xue Re); administering cooling-blood herbs can moderate the Qi and Blood, causing the cycle to gradually delay until it harmonizes and eventually returns to the beginning of the month. If the menstrual blood is pale, scanty, and short in duration, administer blood-nourishing and blood-harmonizing herbs to nourish the Mingmen (Gate of Life), also advancing the cycle to the beginning of the month. Medication should be adjusted according to the woman's fatness, thinness, strength, and weakness. One month may not suffice for alignment; through prolonged regulation, the cycle will eventually align with the waxing moon phase (approximately the 7th to 8th day of the lunar month). This is the method of regulating menstruation. (Some menstrual conditions cannot be forcibly regulated, such as women who menstruate only once a year or continuously throughout the four seasons). Intercourse during the waxing moon phase tends to result in male offspring. Another category of women is obese, with excessive fatty membranes filling the uterus (Zigong). Even if menstruation is regular, this condition causes infertility. They require herbs that open the uterus to dissolve these fatty membranes.
Mr. Yuan states: Chao Yuanfang discusses female pregnancy. In the first month, it is called Taipei (Fetal Embryo), nourished by the Foot Jueyin Liver Meridian. In the second month, it is called Shigao (Beginning Paste), nourished by the Foot Shaoyang Gallbladder Meridian. In the third month, it is called Shitai (Beginning Fetus), nourished by the Hand Shaoyin Heart Meridian. In the fourth month, it begins to receive Water Essence to circulate Blood vessels, nourished by the Hand Shaoyang Sanjiao Meridian. In the fifth month, it begins to receive Fire Essence to form Qi, nourished by the Foot Taiyin Spleen Meridian. In the sixth month, it begins to receive Metal Essence to form sinews, nourished by the Foot Yangming Stomach Meridian. In the seventh month, it begins to receive Wood Essence to form bones, nourished by the Hand Taiyin Lung Meridian. In the eighth month, it begins to receive Earth Essence to form skin and flesh, nourished by the Hand Yangming Large Intestine Meridian. In the ninth month, it begins to receive Stone Essence to form hair, nourished by the Foot Shaoyin Kidney Meridian. In the tenth month, the Zang organs, Fu organs, joints, and Shen (Spirit) are all complete, nourished by the Foot Taiyang Bladder Meridian. This is the general overview. (The embryo manifests from Qi at the onset; Pei is the form of Qi, Gao is the condensation of Qi, Tai is the attachment of form. Pre-heaven controls biological transformation, thus using Water, Fire, Metal, Wood, Earth, and Stone to constrain and transform it; post-heaven develops sequentially, thus following the generation cycle of Wood, Fire, Earth, Metal, and Water. Nourishment follows reverse principles, transformation follows forward principles, achieving natural wonder.) To explore details, after conception in the abdomen, changes occur every seven days, transforming into one another with mutual generation, as detailed in the *Daji Jing*. Currently, miscarriages among women occur mostly in the third, fifth, and seventh months, and less frequently in the second, fourth, and sixth months. Zang organs are Yin, Fu organs are Yang. The third month belongs to the Heart, the fifth to the Spleen, and the seventh to the Lung; all involve the meridians of the Five Zang organs. Yin is prone to deficiency, hence miscarriage is common. If a woman previously miscarried in the third month, the Heart Meridian was injured; one must first regulate the Heart, otherwise, miscarriage will recur in the third month. If she previously miscarried in the fifth month, the Spleen Meridian was injured; one must first treat the Spleen, otherwise, miscarriage will recur in the fifth month. Only in cases of miscarriage within the first month do people remain unaware of the pregnancy, believing merely that conception did not occur, rather than recognizing it as a miscarriage. The first month belongs to the Liver. Anger can cause miscarriage; frequent washing of the lower body opens the orifices and can also cause miscarriage. Once a miscarriage occurs, the Liver Meridian is injured, predisposing to future miscarriages. Most infertile women today have suffered miscarriages in the first month, not because they fail to conceive, but due to early loss. Therefore, after initial intercourse, utmost rest is essential. Avoid further sexual activity to prevent disturbing the uterus. Avoid anger, fatigue, lifting heavy objects, and bathing. Additionally, consume more herbs that nourish the Liver and calm Qi, ensuring the fetus remains secure.
