难以拘泥于一种看法，难道月经推迟这一种情况就是这样的吗？医生应当深入探究其中的道理。）
魏玉横说：徐德滋的女儿，年龄接近二十岁，平素有胁痛等肝病症状，平时月经经常提前来潮，最近忽然超过数日才来。诊脉时，两手关部脉象躁动急疾，两手寸部脉象上溢。观察她的面色，有数十点类似疹子的斑点，颜色有的发青，有的发紫。询问她身上也有，甚至舌头上也有几处。这完全像是阳气热证的表现，然而并没有头痛、恶寒发热等症状，而且能吃下两碗饭。这主要是由于肝火在内炽盛，向上侵犯肺和胃所致。给予生地、枸杞子、麦冬、丹皮、山栀、当归、生白芍、甘草、玄参，让她服用一剂。第二天傍晚时分月经才来，见到她侧卧着，上半身俯在床沿上，呕吐出一盆多的血。询问得知，从上午九点到十一点左右开始出血如涌出，随后感觉心下部好像有一块气向上攻冲，所以必须俯卧，用床沿抵住身体稍感舒适，否则气会上顶导致胸闷窒息。再诊脉，脉象若有若无。推测她是月经过期，乘着肝火上逆而出血，这就是俗称的“倒经”。然而病情如此急骤猛烈，兼之地气（此处指下焦阴寒或病理之气）上攻，症状非常危险。不用大剂量的纯阴药物，怎么能挽回局面？给予熟地黄二两，枸杞子一两，让她连续服用两剂，服药后就能仰卧，血止住了，脉搏也恢复了。第二天忽然出现咳嗽且无痰，这是肺金干燥而肝火尚未平息的表现。将前方药量减半，加入麦冬、沙参、瓜蒌仁、生地，服用八剂后痊愈。痊愈后面上的疹子消退了，舌头上的疹子脱落像痘痂一样。另外顾卜周家的女仆失血，气息微弱濒临死亡，也用前面的药物几剂而治愈。（按语：水、火、风，都属于地气范畴。干姜、附子、白通汤，是治疗地中水气上逆的方法，使用阳刚的药物来扫除浊阴之气。此症是风动火升，所以用纯阴的药物来镇压平息作为治疗方法。）
范氏的女儿，到了十五岁成年之际。忽然生病，晚上睡觉时小便自行遗出，早晨起来昏昏沉沉像喝醉了一样，精神状态与常人完全不同，傍晚时分逐渐清爽，皮肤出现瘾疹，胸膈部迷闷，食欲减少，起初觉得咽痛头晕，已经十多天了。诊脉，脉象弦细而数，这属于血虚火盛。询问她的月经情况，说是前个月月经量大行，失血很多，直到第七天才停止。认为是肝木过盛，克制脾土、欺侮胃土、乘袭肺金所致。克制脾土则脾不统摄血液，所以经血量多；欺侮胃土则胃络溢出，所以腹胀闷、食欲减退；乘袭肺金则肺热，所以出现瘾疹、咽痛。又因为肝藏魂，肺藏魄，这两脏不和，所以导致小便自遗和精神昏昧。给予生地、枸杞子、羚羊角、黑山栀、麦冬、瓜蒌仁、黄连、丹皮、沙参、牛蒡子之类的药物，出入加减，服用六帖后安定下来。后来月经几个月不来，是因为之前失血过多导致的。仍然使用生地、枸杞子、当归、白芍、丹皮、麦冬，少量加入红花，服用八剂后月经来潮。
It is difficult to adhere rigidly to a single perspective; does the condition of delayed menstruation alone exemplify this? Physicians should devote their attention to investigating these matters.
Wei Yuheng stated: The daughter of Xu Dezhi, nearly twenty years old, had a history of liver disease manifesting as hypochondriac pain. Her menses usually arrived early, but recently it was delayed by several days. Upon palpation, the pulses at both Guan positions were restless and rapid, while the pulses at both Cun positions overflowed upward. Observing her complexion, there were dozens of spots resembling rashes, varying in color from cyanotic to purplish. Inquiry revealed similar spots on her body and even a few on her tongue. This closely resembled a syndrome of blazing Yang-heat, yet she lacked headache or aversion to cold with fever, and could consume two bowls of rice. This was primarily due to Liver Fire blazing internally and ascending to invade the Lung and Stomach. She was prescribed Sheng Di Huang (Rehmanniae Radix), Gou Qi Zi (Lycii Fructus), Mai Dong (Ophiopogonis Radix), Mu Dan Pi (Moutan Cortex), Shan Zhi Zi (Gardeniae Fructus), Dang Gui (Angelicae Sinensis Radix), Sheng Bai Shao (Paeoniae Radix Alba), Gan Cao (Glycyrrhizae Radix et Rhizoma), and Xuan Shen (Scrophulariae Radix) for one dose. On the following day, during the afternoon, her menses finally arrived. She was found lying prone, her upper body bent over the edge of the bed, vomiting approximately one basin of blood. It was learned that bleeding had started like a gush around 9–11 AM, followed by a sensation of a mass attacking upward from the epigastrium. Thus, she had to lie prone, pressing against the bed edge for slight relief; otherwise, the rising qi would cause chest oppression and suffocation. Palpation revealed a pulse that was faint and indistinct. It was surmised that her delayed menses, combined with rebellious Liver Fire, caused the bleeding, a condition commonly known as "Reverse Menstruation" (Dao Jing). However, given the suddenness and severity of the condition, compounded by the upward attack of pathogenic qi from the lower jiao, the prognosis was critical. Only large doses of pure Yin-nourishing herbs could reverse this crisis. She was administered Shu Di Huang (Prepared Rehmanniae Radix) two taels and Gou Qi Zi (Lycii Fructus) one tael, to be taken consecutively in two doses. After ingestion, she could lie supine, the bleeding stopped, and her pulse returned. The next day, she suddenly developed dry cough, indicating Dryness of Metal (Lung) and unextinguished Liver Fire. The previous formula was halved, with additions of Mai Dong (Ophiopogonis Radix), Sha Shen (Glehniae Radix), Gua Lou Ren (Trichosanthis Semen), and Sheng Di Huang (Rehmanniae Radix). After eight doses, she recovered. Subsequently, the rashes on her face subsided, and those on her tongue peeled off like scabs. Additionally, a female servant of Gu Bozhou suffered from hemorrhage, appearing near death, and was also cured with a few doses of the aforementioned prescription. [Commentary: Water, fire, and wind all belong to the category of Earth Qi (pathogenic factors arising from the lower body/earth element). Ginger, Aconite, and Bai Tong Tang are used to treat the rebellion of water qi within the earth, employing Yang-acrid substances to sweep away turbid Yin. In this case, Wind moved and Fire rose, so treatment employed pure Yin substances to suppress and calm.]
The daughter of Fan, having reached the age of fifteen (coming of age), suddenly fell ill. She experienced nocturnal enuresis while sleeping at night, and upon waking in the morning, felt dizzy and intoxicated-like, with mental spirit completely disconnected from normal state. By late afternoon, she gradually became clear-headed. She presented with skin urticaria/rashes, chest and diaphragm oppression, and reduced appetite. Initially, she complained of sore throat and dizziness, which had persisted for more than ten days. Pulse diagnosis revealed a wiry, thin, and rapid pulse, indicative of Blood deficiency with excessive Fire. Inquiry into her Tian Gui (menstrual function) revealed that her last menstrual period was heavy, involving significant blood loss, lasting until the seventh day before stopping. This was attributed to excessive Liver Wood suppressing Spleen Earth, insulting Stomach Earth, and attacking Lung Metal. Suppression of Spleen Earth leads to the Spleen's failure to control blood, resulting in heavy menses; insulting Stomach Earth causes overflow of Stomach collaterals, leading to distension, oppression, and anorexia; attacking Lung Metal generates Lung Heat, causing urticaria and sore throat. Furthermore, since the Liver stores the Hun (Ethereal Soul) and the Lung stores the Po (Corporeal Soul), disharmony between these two organs resulted in nocturnal enuresis and mental confusion. She was treated with a modified formula containing Sheng Di Huang (Rehmanniae Radix), Gou Qi Zi (Lycii Fructus), Ling Yang Jiao (Capris Cornu), Hei Shan Zhi Zi (Gardeniae Fructus Carbonized), Mai Dong (Ophiopogonis Radix), Gua Lou Ren (Trichosanthis Semen), Huang Lian (Coptidis Rhizoma), Mu Dan Pi (Moutan Cortex), Sha Shen (Glehniae Radix), and Niu Bang Zi (Arctii Fructus). After six doses, her condition stabilized. Later, her menses failed to arrive for several months due to the prior excessive blood loss. She was again treated with Sheng Di Huang (Rehmanniae Radix), Gou Qi Zi (Lycii Fructus), Dang Gui (Angelicae Sinensis Radix), Bai Shao (Paeoniae Radix Alba), Mu Dan Pi (Moutan Cortex), Mai Dong (Ophiopogonis Radix), with a small addition of Hong Hua (Carthami Flos). After eight doses, her menstruation resumed.
