干道成男。而坤道成女。故男为阳。而女为阴也。气属乎阳。而血属为阴。故男多气。
而女
多血也。阳轻清而阴重浊。故气无形。而血有形也。气惟无形。故充满于中而不露。血惟有
形。故流溢于外而可见也。然是血也。以其初而言之。即先天真一之水。女子十四天癸至。
则源泉之通。自此而始。其往来有信如潮汐之不愆其期。然后血脉调和。而病无由生。一失
其期。便能作疾。而生育之机。亦因以窒矣。故治女病者。以调经为先。而善调经者。以顺
气为主。气顺则经自调。经调则血常足。是以月事既正。新血一生。一交媾之间。而胚胎即
结。血少精多。则精裹血而成男。血多精少。则血裹精而成女。欲得子者。于月事初止之后。
三日之内。新血始生。而气犹清。交感而成胎者必男也。三日之外。新血渐多。而气已浊。
交感而成胎者。必女也。其有交感于三日之外。而亦生男者。必其平素血气不盛。而其来不
浊故也。其有交感于三日之内。而亦生女者。必其平素血气太盛。而其来不清故也。其有血
气未尝不足。而月事又调。宜乎成胎也。而久不生育者。何也。是必男子精气不稠。或精寒
不相交结故也。而非女子之病也。其有男子精气素充。而又无子者。是必女子子宫之寒。不
能摄精故也。而非男子之病也。然何以知子宫之寒哉。盖女子尺脉常盛。若沉细而迟。如无
所动。则子宫之寒可知矣。其有子宫不寒。而亦无子者。必其血不足。或痰有余故也。然果
何以知其血之不足。痰之有余哉。亦视其形之肥瘦而已。盖瘦人多血虚。血虚则不能凝精。
肥人多湿痰。湿痰流注于下焦。则痰与血混淆。而化气不清。故亦不能凝精也。其有瘦人肥
人。而亦未尝无子者。又何也。盖瘦人多血虚。道其常也。若月事既调。而无热症。则血常
滋润而不枯。是以能生育也。肥人多湿痰。亦道其常也。然或肌肉不甚浮。而色不甚白。饮
食无浓味。则湿痰亦少。而血气常清。是以亦能生育也。由是观之。则女子之血实。所以宰
生生化化之机也。方其未成胎也。则此血周流而不息。应期而至。及其既成胎也。则此血荣
养于内以护其胎。今妇人初有孕。即头眩恶心。或发呕吐多厌饮食。而常思酸者。乃足厥阴
肝经养胎也。肝主风。故头眩。肝有余。则恶心呕吐。肝胜脾。故多厌饮食。肝喜酸。故常
思酸也。过此则诸经轮次养胎。其七八月之间。两足浮肿者。足太阴脾经养胎也。脾注四肢
。
故两足浮肿也。两手不浮肿而独见于两足者何也。盖脾本足之阴经。况此时胎气已坠下。故
不能不见于两足也。每一月。则一经养之。十个月。则十经养之。十月满足而后产焉。其
余二经则又养于既产之后。而化血化乳汁矣。是乳汁亦血也面其色白者。何也。盖胸前部倍
属太阴肺经。乃西方庚辛金也。金色本白。血从阴分而来。故变赤而为白也。凡血去多。则
令人虚。今乳汁既为血。亦不宜去多也。然其来也。恒有余其出也。无尽止足。以饮小儿。
而其母不觉其虚者。何也。盖人身之血。皆资于饮食以生者也。饮食入胃。游溢精气。上输
于肺。从肺之部位而出。故成乳汁。妇人既产。而饮食倍于常日。既产之后。又属足阳明胃
经养之。乳傍属阳明。故乳汁多受于此处。胃能化饮食。饮食能生血。饮食既足。则血亦足
。血既足。则其化为乳汁也。自无穷尽矣。何至令人虚乎。甘属胃。故乳汁亦甘。白属肺。
故乳汁亦白。是以知既产之后。乃肺胃二经养之也。小儿二三岁。其母复有妊儿饮魃乳。即
黄瘦泄泻者。以乳汁味酸。正足厥阴肝经养胎之日。肝能克脾。故儿饮之即泻也。当此之时
。肺经失令。胃土无权则所以滋养乎血者。已无所籍。几何而不为儿之病哉。此特论胎前产
后之事。而原其本于血。归其功于十二经耳。若夫胎前产后之症。又各具于诸症条下。而不

The back and spine are penetrated by the Kidney meridian and belong to the Taiyang (Greater Yang) meridian. The reason for pain here is due to excessive sexual activity and neglect of physical labor, resulting in an empty spine and depleted marrow.
If pathogenic wind invades while the body is deficient, stiffness will occur immediately, preventing flexion and extension.

Men are formed according to the Qian (Heaven/Yang) principle, and women according to the Kun (Earth/Yin) principle. Thus, men are Yang and women are Yin. Qi belongs to Yang, and Blood belongs to Yin. Therefore, men have more Qi, and women have more Blood. Yang is light and clear, while Yin is heavy and turbid. Thus, Qi has no fixed form, whereas Blood has a fixed form. Because Qi is formless, it fills the interior without being visible; because Blood has form, it flows outward and is visible. However, this Blood, speaking from its origin, is the primordial True One Water. When a girl reaches fourteen years of age, Tian Gui (menstruation and reproductive essence) arrives, and the flow of her source begins. Its coming and going are punctual, like tides that do not miss their schedule. Then, the blood vessels harmonize, and disease has no opportunity to arise. If this schedule is lost, disease arises, and the mechanism of reproduction becomes blocked. Therefore, treating female diseases prioritizes regulating menstruation, and those skilled at regulating menstruation prioritize smoothing Qi. When Qi is smooth, menstruation regulates itself; when menstruation is regulated, Blood remains sufficient. Thus, after menstruation is regular and new Blood is generated, conception occurs during intercourse. If there is less Blood and more Essence, Essence wraps around Blood to form a male fetus; if there is more Blood and less Essence, Blood wraps around Essence to form a female fetus. Those desiring a son should conceive within three days after menstruation stops. At this time, new Blood has just begun to generate, and Qi is still pure; conception during this period will surely result in a male. After three days, new Blood increases, but Qi becomes turbid; conception during this period will surely result in a female. Those who conceive after three days and still bear a son must have had weak Blood and Qi normally, and their menstrual blood was not turbid. Those who conceive within three days and bear a daughter must have had overly abundant Blood and Qi normally, and their menstrual blood was not clear. For those whose Blood and Qi were never insufficient and whose menstruation was regular, yet they fail to conceive for a long time, why? It must be that the man's Essence is not dense, or his Essence is too cold to combine; this is not the woman's fault. For men whose Essence is naturally abundant but who have no children, it must be that the woman's uterus is cold and cannot retain Essence; this is not the man's fault. How do we know the uterus is cold? Generally, the Chi pulse (pulse position at the wrist corresponding to the Kidneys and Mingmen) in women is often vigorous. If it is deep, thin, and slow, appearing motionless, then uterine cold can be known. For those whose uterus is not cold but still have no children, it must be due to insufficient Blood or excess Phlegm. How do we know if Blood is insufficient or Phlegm is excessive? We look at the person's body shape. Thin people tend to have Blood deficiency; if Blood is deficient, it cannot condense Essence. Fat people tend to have Damp-Phlegm; if Damp-Phlegm flows downward to the Lower Jiao, Phlegm and Blood mix, and the transformed Qi is not clear, so it also cannot condense Essence. Why do both thin and fat people sometimes have children? Thin people having Blood deficiency is the norm. However, if menstruation is regular and there are no heat symptoms, Blood remains moist and not dry, allowing for reproduction. Fat people having Damp-Phlegm is also the norm. But if muscles are not very puffy, complexion is not very white, and diet lacks rich flavors, then Damp-Phlegm is minimal, and Blood and Qi remain clear, allowing for reproduction. From this, we see that Women's Blood actually governs the mechanism of generation and transformation. Before conception, this Blood circulates endlessly and arrives on schedule; after conception, this Blood nourishes internally to protect the fetus. Now, when a woman first becomes pregnant, she may experience dizziness, nausea, vomiting, aversion to food, and cravings for sour foods. This is the Foot-Jueyin Liver Meridian nourishing the fetus. The Liver governs Wind, hence dizziness; Liver excess causes nausea and vomiting; Liver overacting on Spleen causes aversion to food; the Liver prefers sour, hence cravings for sour things. After this stage, other meridians take turns nourishing the fetus. Between the seventh and eighth months, swelling in both feet indicates the Foot-Taiyin Spleen Meridian is nourishing the fetus. The Spleen governs the four limbs, hence foot swelling. Why do hands not swell, only feet? The Spleen is a Foot-Yin meridian, and at this time, fetal Qi has descended, so swelling appears in the feet. Each month, one meridian nourishes; ten months, ten meridians nourish. After ten months full term, birth occurs. The remaining two meridians nourish after birth, transforming into Blood and Milk. This milk is also Blood, but why is it white? The chest area specifically belongs to the Foot-Taiyin Lung Meridian, which corresponds to Metal in the West (Geng-Xin). Metal is inherently white. Blood comes from the Yin aspect, changing from red to white. Excessive loss of Blood causes deficiency. Since milk is Blood, it should not be lost excessively. Yet, milk production is often abundant, and discharge is endless to feed the infant, without the mother feeling deficient. Why? Human Blood is generated from dietary intake. Food enters the Stomach, extracts Jing-Qi, transports it upward to the Lung, and exits from the Lung's region to become milk. After childbirth, dietary intake doubles, and the Foot-Yangming Stomach Meridian nourishes the postpartum state. The area beside the breast belongs to the Yangming meridian, where milk is largely produced. The Stomach digests food, and food generates Blood. If food intake is sufficient, Blood is sufficient. If Blood is sufficient, its transformation into milk is inexhaustible, causing no deficiency. Sweet flavor belongs to the Stomach, so milk is sweet; White color belongs to the Lung, so milk is white. Thus, we know that after childbirth, the Lung and Stomach meridians provide nourishment. When infants are two or three years old, if the mother becomes pregnant again and continues breastfeeding, and the child suffers from yellow emaciation and diarrhea, it is because the milk tastes sour, corresponding to the time when the Foot-Jueyin Liver Meridian nourishes the fetus. The Liver controls the Spleen, so drinking this milk causes diarrhea. At this time, the Lung Meridian loses its command, and Stomach Earth lacks authority, so the means to nourish Blood have no basis. How can the child not suffer? This discussion focuses on pre- and post-natal matters, tracing the root to Blood and attributing merit to the Twelve Meridians. Symptoms specific to pre- and post-natal periods are listed under respective symptom categories and are not discussed in detail here.
