妇女养生与治疗的关键在于血，血与精气结合，胎孕才能形成。想要了解她们的病症，只能通过月经的情况来观察；想要治疗她们的疾病，只能通过调理阴分来实现。因为经血就是血，血属于阴。阴气对应月亮，所以月经每月如期而至，这是正常的生理规律。当发生病变时，就会出现或提前或推后的情况，有的一个月来两次，有的两个月才来一次，有的枯竭闭经不通，有的频繁出血不止，有的先疼痛后行经，有的先行经后疼痛，有的经色淡、黑或紫，有的凝结成条状或片状瘀块，有的因精血不足而化为白带白浊，有的因子宫虚冷导致阳气无法生化，有的因血中伏热导致阴气无法凝聚成形，有的因气血痞塞、子宫松弛不收而导致月水不通。凡此种种，都是真阴的病变。真阴既然生病，那么阴血不足的人，就不能孕育胎儿；阴气不足的人，就不能固摄胎儿。因此，求子的方法，首要在于调理月经。
天地生生不息的道理，只在于阴阳二气的和谐。阴阳相合，则生养之理完备；阴阳分离，则人的体质确定。所以男子禀受阳气，女子禀受阴气；男子象征太阳，女子象征月亮。男子的生机是一天发动一次，女子的生机是一个月循环一周。半夜子时，是男子生机发动的时刻；月经来潮的日子，是女子生机萌发的时刻。如果能在这生生不息的时候，加以注意保护，就可以祛除疾病、延长寿命，这是一定的道理。我常常想到世间的女子，比男子较为安逸。至于富贵人家，深闺中的妇女，穿着锦衣美食，居住在幽深的房间，没有饥寒风霜和体力劳苦的辛苦，然而患痨瘵（慢性消耗性疾病）的却偏多，疾病时常发作，这是什么原因呢？大概是因为她们受到的病邪很轻微，起因于被忽视而自己不知道罢了。大抵女子到了十四岁，天癸（促进生殖机能成熟的物质）到来，月经按时来潮，此时生机蓬勃，凡是关于生育的事情，都源于此。只是在她月经即将来潮的时候，新的血液尚未生成，旧的血液将要排出，心中必然有烦躁的状态，不同于平日。那时若能自知月经将要来行，一切起居生活，都应该加以注意调养，劳累、生气恼怒，都不宜触犯，最不可吃冷的食物，坐卧在冷的地方。因为寒冷是肃杀之气，最伤害生机。况且在月经来行的时候，全身四肢百骸，毛孔都张开，然后旧血进入冲脉向下排出，那时如果一旦受到寒气侵袭，不论在身体的哪个部位，那些想要排出的血液，就会停留而不运行。起初只是像毫毛一样聚集，随着每日血液运行周身，到达凝滞的地方，就停滞不运行，日积月累增多，这就是瘀血、痨症、瘕聚痞块、瘰疬、膈噎、行经疼痛短缩等病症产生的由来。至于月经干净后的一两天内，全身四肢百骸都在生成新血，这时如果一旦受到冷气侵袭，则生机被郁结遏制，无论哪里受到寒冷，哪里就不能生发，这就是血枯、痨症、面色黄瘦无力、心脾胀闷、月经过期、白带等各种病症产生的由来。在当时感受到的病邪非常轻微，原本并不觉得，等到疾病已经形成，医生又根据症状进行治疗，不探究病因来源，这就是妇人容易多病的原因。况且在富贵之家，妇女向来习惯骄纵任性，又善于掩饰，甜瓜冷果，一时可口，禁止不了，且喜欢吃生冷之物，则胃气内部寒冷，见到热食就怕，不知道一时的爽快有限，日久之后的疼痛难当，以至于不能生育，种种受害都由于此，现在特别指出这一点。天下的妇女，如果在月经来行时，能戒除生冷、冷气、恼怒，像产后调养那样对待自己，每个月不过五六天，各种疾病自然消除。这时候服药，也容易见效，所以去除积滞、行散瘀血，必须在月经来行时，趁势导下；补养调理，必须在月经干净后一天，乘机辅助。这样奏效必定比往日迅速，这其中实在具备至为微妙的玄机。无奈天下的庸医，茫然如雾露之中，此后看到这本书的人，相信并遵照实行。如果有患病妇女，半年之内，有不脱离身体安康的，我发誓割断我的舌头。这次因为《衍庆编》完成，特意撰写这篇论述附在后面，使天下的妇女知道，不仅永远没有疾苦，而且广嗣多男，也或许能稍微助益天下生育的大德吧。
Women's health and treatment focus on blood; when blood combines with essence, conception is achieved. To observe their ailments, one must look to the menstrual cycle; to treat them, one must regulate the Yin aspect. Menstrual blood is blood, and blood belongs to Yin. Yin corresponds to the moon, so menstruation arrives monthly as scheduled; this is the normal state. When pathology occurs, menstruation may come early or late, twice a month, or once every two months; it may be absent and obstructed, or frequent and unceasing; pain may precede flow or follow it; color may be pale, black, or purple; blood may coagulate into strips or flakes; insufficient essence and blood may transform into leukorrhea (white discharge) or turbid discharge; uterine deficiency-cold may prevent Yang Qi from generating and transforming; latent heat in the blood may prevent Yin Qi from condensing; Qi and Blood stagnation with uterine laxity may obstruct menstruation. All these are disorders of True Yin. Once True Yin is diseased, those with insufficient Yin-blood cannot nourish the fetus, and those with insufficient Yin-Qi cannot secure the fetus. Therefore, methods for seeking pregnancy prioritize regulating menstruation.
The principle of generation in Heaven and Earth lies solely in the interaction of Yin and Yang Qi. When they combine, the principle of life is complete; when separated, human constitution is fixed. Thus, men inherit Yang, women inherit Yin; men resemble the Sun, women resemble the Moon. Men's vital energy activates daily; women's vital energy cycles monthly. The hour of Zi (midnight) is when men's vital energy arises; the days of menstruation are when women's vital energy sprouts. If one pays attention to protection during these times of generation, disease can be expelled and longevity extended; this is a fixed principle. I often consider that women in the world are generally more leisurely than men. Specifically, women in wealthy families, living in deep chambers with fine clothes and food, free from hunger, cold, wind, dew, and physical labor, still suffer disproportionately from consumption (Lao Zhai) and frequent illnesses. Why? Because the pathogenic factors affecting them are subtle, arising from neglect without their awareness. Generally, at age fourteen, Tian Gui (the substance promoting reproductive maturity) arrives, and menstruation begins regularly. At this time, vital energy is vigorous; all matters of birth and nurturing stem from here. However, just before menstruation flows, new blood has not yet formed while old blood is about to leave, inevitably causing irritability different from usual. If one realizes menstruation is imminent, daily activities should be carefully regulated. Overwork, anger, and annoyance should be avoided. Most importantly, one must not consume cold foods or sit/lie in cold places. Coldness is a肃杀 (killing/drying) Qi that most harms vital energy. Moreover, during menstruation, all limbs and pores open, allowing old blood to enter the Chong Mai (Penetrating Vessel) and flow downward. If cold Qi invades at this time, regardless of location, the blood intended to flow will stagnate. Initially, it gathers like hair; as daily blood circulates, it reaches the stagnant area and stops. Accumulating day by day, this gives rise to blood stasis, consumption, masses (Jia), palpitations, scrofula, dysphagia, and painful, shortened menstruation. One to two days after menstruation ends, new blood is generated throughout the body. If cold Qi invades then, vital energy is suppressed. Regardless of where cold strikes, that area fails to generate, leading to blood depletion, consumption, sallow complexion, weakness, heart-spleen distension, delayed menstruation, and leukorrhea. The initial invasion is subtle and unnoticed; by the time disease manifests, physicians treat symptoms without investigating the root cause, explaining why women suffer many diseases. Furthermore, women in noble households are accustomed to being willful and skilled at concealment. They crave sweet melons and cold fruits, which are hard to prohibit, and enjoy raw/cold foods, causing internal Stomach Qi coldness and aversion to heat. They do not realize that momentary pleasure is limited, while long-term pain is unbearable, leading to infertility. All such harm stems from this, which is now pointed out. Women everywhere who avoid raw/cold foods, cold Qi, and anger during menstruation, treating themselves as in postpartum care, will find diseases eliminated within five to six days each month. Medication taken at this time yields quick results. Thus, removing accumulation and moving stasis should be done during menstruation to take advantage of the flow; tonifying and regulating should be done one day after menstruation ends to assist the process. Efficacy will be faster than before, containing profound mechanisms. Regrettably, mediocre physicians are confused like fog and dew. Those who read this book should believe and follow it. If any sick woman does not recover fully within half a year, I vow to cut out my tongue. With the completion of *Yanqing Bian*, I append this treatise so women worldwide may know: not only will they be free from suffering, but also bearing many sons will slightly contribute to the great virtue of generation in the world.
