罗周彦曰∶妇人得阴柔之体，以血为本。阴血如水之行地，阳气若风之旋天。故风行则水动，阳畅则血调，
此自然之理也。考古方耗气以调其经。夫太冲者，气也。任脉者，血也。气升则升，气降则降，血随气行。若
独耗其气，血无所施。正气既虚，邪气必胜，而百病生焉，经安得调乎。况心生血，脾统之，胃为卫之元，养

慎斋按∶以上五条，序调经之法，莫先于顺气开郁。而顺气开郁，则又戒不可专耗其气。当以实脾养心，为
调经之要法也。经云百病皆生于气，而于妇人为尤甚。妇人之病，先于经候不调。但妇人以血用事，经水虽属血
病，若竟从血分求疗，未得病机之要者也。若从气分求责，而调经知所本矣。
初虞世曰∶女子十四天癸至，任脉通，月事以时下。其来不可过与不及，多与少，反此皆谓之病。不行尤

无以滋养，其能行乎。但服养气益血诸药，天癸自行也。又有一种妇人盛实，月经瘀闭，利之则行，自有证候。
罗周彦说：妇人禀受阴柔之体，以血为根本。阴血如同水在大地上流动，阳气好似风在天空中旋转。因此风吹则水动，阳气通畅则血液调和，这是自然的道理。考察古代方剂，多用耗气的方法来调理月经。太冲脉主管气，任脉主管血。气上升则随之上升，气下降则随之下降，血液随着气的运行而运行。如果单独耗损气，血液就失去了运行的动力。正气既然虚弱，邪气必然亢盛，从而产生各种疾病，月经又怎能调好呢？况且心主生血，脾统摄血液，胃是卫气的本源，养护心脏则血液生成，充实脾胃则血液充足。气旺盛则血液运行顺畅，怎么可以单独耗损气呢，这是调理月经的关键所在。行经期间，应当戒除暴怒，愤怒会损伤冲脉和任脉。远离房事，纵欲过度会伤害血海。一旦有抑郁情绪，陈旧之血必定停滞，流注于腰胁部，注入腿膝部位，与新生的血液相互搏结，就会导致疼痛不止。瘀血散于四肢，则出现麻木不仁的症状。瘀血进入血室，则出现寒热交替不定的症状。这些都是由四时气候异常和七情内伤所导致的。
慎斋按语：以上五条，叙述了调理月经的方法，没有比顺气开郁更优先的。而顺气开郁，关键在于不可专门耗损气。应当以实脾养心，作为调理月经的重要方法。医经说百病都生于气，而在妇人身上尤为严重。妇人的疾病，首先表现为月经不调。虽然妇人以血为主要生理基础，月经虽属于血分病变，但如果仅仅从血分寻求治疗，就没有抓住疾病的机理关键。如果从气分追究病因，那么调理月经就知道其根本所在了。
初虞世说：女子十四岁时天癸至，任脉通畅，月经按时来潮。月经来潮的量不可过多或过少，量多量少，违背正常情况都称为疾病。月经闭止尤其严重，会导致百病丛生。血液既不能滋养全身各处，就会出现头发脱落、面色萎黄、身体消瘦的症状。血虚则发热，津液不足则燥气炽盛。燥气炽盛则肺金受邪，肺金受邪则肺部咳嗽，咳嗽导致咳血、吐血的病症形成。医生见到月经不行，就用虻虫、水蛭等破血逐瘀的药物；见到发热，就用清热泻火的寒凉药物，导致经血枯竭，没有物质基础来滋养身体，月经怎么能正常运行呢？只要服用养气益血的药物，天癸自然会自行恢复。另外有一种妇人体质强盛，月经瘀滞闭止，使用通利药物后月经即可通行，自有相应的证候表现。
Luo Zhouyan stated: Women possess a yin-soft constitution and regard blood as their root. Yin-blood is like water flowing on the earth, while yang-qi is like wind rotating in the sky. Therefore, when wind blows, water moves; when yang-qi is smooth, blood is harmonized. This is the principle of nature. Examining ancient prescriptions, they often used methods that deplete qi to regulate menstruation. The Chong Mai (Penetrating Vessel) governs qi, and the Ren Mai (Conception Vessel) governs blood. When qi ascends, it ascends; when qi descends, it descends; blood follows the movement of qi. If one solely depletes qi, blood has no power to act. Once healthy qi is deficient, pathogenic qi will inevitably prevail, giving rise to myriad diseases. How can menstruation be regulated then? Moreover, the Heart generates blood, the Spleen controls it, and the Stomach is the origin of Wei Qi (Defensive Qi). Nourishing the Heart leads to blood generation, and strengthening the Spleen leads to sufficient blood. When qi is abundant, blood flows smoothly. How can one solely deplete qi? This is the most crucial point in regulating menstruation. During menstruation, one must guard against violent anger, for anger damages the Chong and Ren vessels. One should avoid sexual intercourse, as excessive desire injures the Sea of Blood. If there is any depression or stagnation of emotions, old blood will surely stagnate, flowing into the waist and hypochondrium, and pouring into the legs and knees. When it contends with new blood, it causes unceasing pain. If it scatters to the four limbs, it results in numbness and insensitivity. If it enters the Blood Chamber, it causes alternating chills and fever. All these are caused by the Four Qi (Four Seasons' Climate) and Seven Emotions.
Shen Zhai commented: The above five points outline the methods for regulating menstruation, prioritizing the smoothing of qi and resolving stagnation. However, in smoothing qi and resolving stagnation, one must not specialize in depleting qi. Instead, one should strengthen the Spleen and nourish the Heart as the essential method for regulating menstruation. The Classics state that all diseases arise from qi, which is especially true for women. Women's illnesses first manifest as irregular menstruation. Although women rely on blood for physiological functions, and menstruation belongs to blood disorders, seeking treatment solely from the perspective of blood fails to grasp the key mechanism of the disease. If one seeks the cause from the perspective of qi, then one knows the root of regulating menstruation.
Chu Yushi said: At age fourteen, Tian Gui (Essence of Menstruation) arrives in women, the Ren Mai becomes patent, and menstruation occurs at regular intervals. Its flow should not be excessive nor insufficient. Both too much and too little are considered pathological. Amenorrhea is particularly severe and gives rise to myriad diseases. Since blood cannot nourish the body, hair falls out, the face turns sallow, and the body emaciates. Blood deficiency causes fever, and insufficient fluids lead to blazing dryness-qi. Blazing dryness-qi damages Metal (Lung), and when Lung Metal is damaged, coughing occurs, leading to hemoptysis and vomiting blood. Physicians, seeing amenorrhea, use blood-invigorating drugs such as *Tabanus* (Mengchong) and *Hirudo* (Shuizhi); seeing fever, they use cold drugs to clear heat. This exhausts menstrual blood, leaving nothing to nourish the body, so how can menstruation proceed? One should merely take herbs that nourish qi and benefit blood, and Tian Gui will recover naturally. Additionally, there are some women with robust constitutions who suffer from menstrual stasis and obstruction; using purgative or draining methods will restore flow, presenting specific clinical manifestations.
