答：妇女是各种阴气汇聚之处，常与湿气相伴。女子十四岁以后，阴气浮盛外溢，思虑杂念萦绕心头，内伤脏腑，外形容貌受损。恶血积于体内，气脉耗竭。或者饮食没有节制，造成多种损伤；或者产后疮疡未愈，就进行房事；或者行走时受风侵袭，在悬挂的便桶上排便，风气从下部侵入，从而形成十二种顽固疾病（另一种说法是三痼之疾）。这就是妇科单独设立一门的原因。如果是因四季节气变化，虚实冷热等因素导致的疾病，治疗法则与男子相同。只有妊娠期间兼患其他疾病时，需避开有毒药物，恐怕会伤害胎儿罢了。大抵上，妇女因为慈爱、眷恋、憎恨、喜爱、嫉妒、忧愁、愤怒等情绪，执着坚定牢固，情感难以自我控制，所以致病根深蒂固，治疗难以痊愈。因此妇女的疾病比男子多一倍，原因就在这里。
答：所谓“天癸”，是指壬癸北方属水的天干。壬为阳水，与丁相配而化木；癸为阴水，与戊相合而化火。医经说：水和火，是阴阳的象征征兆。况且妇女是各种阴气汇聚之处，以阴类同阴，所以得到水的癸干之名。女子到了二七（十四岁），肾气完全充盛，冲脉和任脉流通顺畅，经血逐渐充盈，按时而下。天真之气特别下降并与之交合，所以称为“天癸”。《内经》说：女子十四岁天癸至，任脉通畅，太冲脉旺盛，月经按时来潮，所以能够受孕。然而冲脉为血海，任脉主司胞胎，阴静则血海满盈，二者相互资助，所以能够生育。
答：女子十四岁时天癸至，肾气完全充盛，冲脉和任脉流通，血液逐渐充盈，按时而下。通常每三十天左右来一次月经，如果延期则是病态，所以称为“经候”。所谓“经”，就是常规的意思；“候”，是指观察一身阴阳的状态。经常之气，守候时机而至，就像潮汐按时应期一样。天真之气与之流通，所以每月行经一次。身体平和则不违背其周期，所以称为“经候”。又名“月水”。
Answer: Women are the gathering place of all Yin energies and often reside with dampness. After the age of fourteen, Yin energy floats and overflows. Various thoughts pass through the mind, causing internal injury to the Zang-Fu organs and external damage to physical appearance. Evil blood fills the interior, and Qi and meridians are exhausted. Or, due to unregulated diet, multiple injuries occur. Or, postpartum sores have not healed, yet sexual intercourse takes place. Or, while walking in the wind, one defecates on a suspended toilet, allowing wind to enter from below, thereby forming twelve chronic diseases (or alternatively, three chronic diseases). This is why a separate department for women's diseases was established. If illnesses arise from the changes of the four seasons' solar terms, or from deficiency-excess, cold-heat patterns, the treatment methods are the same as those for men. Only when pregnancy is complicated by other diseases must toxic medicines be avoided, lest they harm the fetus. Generally speaking, women are prone to attachment and firmness in emotions such as compassion, attachment, hatred, love, jealousy, worry, and anger, which are difficult to control. Therefore, the root of their disease is deep, and healing is difficult. This is why women suffer from twice as many diseases as men.
Answer: "Tian Gui" refers to the Heavenly Stems Ren and Gui, associated with Water in the North. Ren is Yang Water, pairing with Ding to transform into Wood; Gui is Yin Water, combining with Wu to transform into Fire. The classics state: Water and Fire are the manifestations of Yin and Yang. Since women are the gathering place of all Yin energies, aligning Yin with Yin, they correspond to the Gui stem of Water. At the age of two sevens (fourteen years old), Kidney Qi reaches full maturity, the Chong and Ren meridians flow smoothly, menstrual blood gradually fills up, and descends at the appropriate time. The Tian Zhen (innate) Qi descends specifically to engage with this process, hence it is called "Tian Gui." The *Nei Jing* states: At fourteen, Tian Gui arrives, the Ren Meridian becomes patent, the Tai Chong Meridian flourishes, menstruation occurs regularly, and thus conception is possible. The Chong Meridian serves as the Sea of Blood, and the Ren Meridian governs the uterus. When Yin is still, the sea of blood fills; these two mutually support each other, enabling reproduction.
Answer: When girls reach fourteen, Tian Gui arrives, Kidney Qi matures fully, the Chong and Ren meridians flow, blood gradually fills, and menstruation descends on schedule. It typically occurs once every thirty days; if delayed, it indicates pathology, hence the term "Jing Hou" (Menstrual Period). "Jing" means regularity; "Hou" refers to observing the Yin and Yang of the whole body. The regular Qi arrives waiting for its time, just as tides respond to the moon. The Tian Zhen Qi flows with it, resulting in monthly menstruation. When the body is in harmony, the cycle is not violated, hence it is called "Jing Hou." It is also known as "Yue Shui" (Monthly Water).
