7.妇人从人不专主, 病多忧忿郁伤情, 血之行止与顺逆, 皆由一气
率而行.
【注】妇人从人, 凡事不得专主, 忧思, 忿怒, 郁气所伤, 故经病因
于七情者居多. 盖以血之行, 止, 顺, 逆, 皆由一气率之而行也.
8.血者水谷之精气, 若伤脾胃何以生, 不调液竭血枯病, 合之非道
损伤成.
【注】血者, 水谷之精气也. 在男子则化为精, 在妇人则化为血, 上
为乳汁, 下为月水. 若内伤脾胃, 健运失职, 饮食减少, 血无以生,
则经必不调. 亦有女子天癸既至, 逾期不得与男子合, 未期思与男子
合,与夫经正行时而合, 此皆合之非道, 亦致不调. 或过淫, 合多则
液竭; 产多, 乳众则血枯, 亦皆能损伤阴血致成经病也.
9.血从阳化色正红, 色变紫黑热之征, 黄泔淡红湿虚化, 更审瘀块
黯与明.
【注】血属阴, 从阳化, 故其色以正红为正, 虽有经病, 亦易为治也
.若色变深红, 紫黑, 乃热之征也. 或黄如米泔, 乃湿化也. 浅淡红
白,乃虚象也. 更当审其有瘀, 有块, 色黯, 色明以治之. 若黯而紫
黑,兼见冷证, 多属寒凝; 若明而紫黑, 兼见热证, 多属热结也.
7. 妇女在家庭中往往不能自主做主，容易因忧虑、愤恨和郁结而损伤情志。血液的运行与停止、顺畅与逆乱，都受气的统率而运行。
【注】妇女依附于丈夫，凡事难以自主，若受到忧思、愤怒、郁气等情志因素的损伤，因此月经病因多由七情（喜、怒、忧、思、悲、恐、惊）引起。这是因为血液的运行、停止、顺畅或逆乱，都是由气来统率运行的。
8. 血是水谷精微中的精气所化生，如果脾胃受伤，何以生成？不调、液竭、血枯的病证，多是由于房事不节造成的损伤而成。
【注】血，是水谷精微中的精气。在男子则化为精，在女子则化为血，上行成为乳汁，下行成为月经。如果内伤脾胃，健运功能失职，饮食减少，血就无法生成，那么月经必然不调。也有女子天癸（促进生殖机能发育成熟的物质）已经到来，过了婚龄却未能与男子交合，未到婚龄却思念与男子交合，或者在月经正常行经期间进行房事，这些都属于房事不节，也会导致月经不调。或者纵欲过度，性交频繁则津液枯竭；生产过多，哺乳频繁则血液枯少，这些都足以损伤阴血从而形成月经病。
9. 血随阳气变化而呈现正红色，颜色变为紫黑是热象的征候，黄色如米泔水或淡红色是湿邪与虚损化生的表现，更应审查是否有瘀血、血块，以及颜色的晦暗或鲜明。
【注】血属于阴，但随阳气而变化，所以其颜色以正红为正常，即使有月经病，也易于治疗。如果颜色变为深红、紫黑，这是热的征象。或者黄如米泔水，这是湿邪化生的表现。浅淡的红白色，是虚损的征象。更应当审查是否有瘀血、血块，以及颜色的晦暗或鲜明来进行治疗。如果颜色晦暗且紫黑，兼见寒证，多属于寒凝；如果颜色鲜明且紫黑，兼见热证，多属于热结。
7. Women often lack autonomy in the family, making them prone to emotional injury from worry, resentment, and depression. The flow and cessation, smoothness and reversal of blood are all governed by Qi (vital energy) for its movement.
[Note] Women depend on their husbands and cannot take full charge of matters. Injury caused by worry, anger, and stagnant Qi means that menstrual disorders are mostly due to the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright). This is because the movement, cessation, smoothness, or reversal of blood are all directed by Qi.
8. Blood is the refined essence derived from water and grain. If the Spleen and Stomach are injured, how can it be generated? Disorders such as irregular menstruation, exhaustion of fluids, and withered blood are often caused by damage from improper sexual conduct.
[Note] Blood is the refined essence of water and grain. In men, it transforms into Essence (Jing); in women, it transforms into Blood. It ascends to become milk and descends to become menstruation. If internal injury damages the Spleen and Stomach, impairing their transportation and transformation functions, leading to reduced dietary intake, Blood cannot be generated, resulting in irregular menstruation. There are also cases where a woman has reached menarche but has not cohabited with a man past the appropriate age, or desires cohabitation before the appropriate age, or engages in intercourse during normal menstruation. These constitute improper sexual conduct, which also leads to irregular menstruation. Excessive lust and frequent intercourse deplete Body Fluids; multiple births and frequent breastfeeding deplete Blood. All these can damage Yin and Blood, causing menstrual disorders.
9. When Blood transforms according to Yang, its color is normally red. A change to purple-black indicates Heat. Yellow like rice washings or pale red indicates transformation from Dampness and Deficiency. One must further examine whether there is Blood Stasis, clots, and whether the color is dull or bright.
[Note] Blood belongs to Yin but transforms under the influence of Yang; thus, its normal color is red. Even if menstrual disorders exist, they are easy to treat. If the color becomes deep red or purple-black, it is a sign of Heat. If yellow like rice washings, it indicates transformation from Dampness. Pale red or white indicates Deficiency. One must further examine for Blood Stasis, clots, and whether the color is dull or bright to guide treatment. If the color is dull and purple-black, accompanied by Cold symptoms, it mostly belongs to Cold Coagulation. If the color is bright and purple-black, accompanied by Heat symptoms, it mostly belongs to Heat Binding.
