诸阳聚于头，则面为阳中之阳，鼻居面中央，而阳明起于 中，一身之血运到面鼻，到面鼻阳部。皆为至清至精之
血矣。酒性善行而喜升，大热而有峻急之毒。多酒之人，酒气熏蒸面鼻，得酒血为极热，热血得冷为阴气所抟，污浊凝
结，滞而不行，宜其先为紫而后为黑色也。须用融化滞血使之得流，滋生新血可以运化，病乃可愈。予为酒制四物汤，
加炒片、茯苓、陈皮、生甘草、酒红花，生姜煎，调五灵脂末饮之。气弱者，加酒黄 。无有不应者。
阳施阴化，胎孕乃成。血气虚损，不足荣养，其胎自堕。或劳怒伤情，内火便动，亦能堕胎。推原其本，皆因于热。
火能消物，造化自然，《病源》乃谓风冷伤于子脏而堕，此未得病情者也。
予见贾氏妇，但有孕至三个月左右必堕。诊其脉，左手大而无力，重取则涩，知其少血也。以其妙年，只补中气，
使血自荣。时正初夏，教以浓煎白术汤下黄芩末一钱，服三四十帖，遂得保全而生。因而思之，堕于内热而虚者，于理
为多。曰热曰虚，当分轻重。好生之工，幸毋轻视。
世之难产者，往往见于郁闷安佚之人，富贵奉养之家。若贫贱辛苦者无有也。方书止有瘦胎饮一论，而其方为湖阳
公主作也，实非极至之言。何者？见有此方，其难自若。予族妹苦于难产，后遇胎孕，则触而去之，余甚悯焉。视其形
肥而勤于针指，构思旬日，忽自悟曰∶此正与湖阳公主相反。彼奉养之人，其气必实，耗其气使和平，故易产。今形肥
知其气虚，久坐知其不运，而其气愈弱。久坐胞胎因母气不能自运耳。当补其母之气，则儿健而易产。今其有孕至五六
个月，遂于《大全方》紫苏饮加补气药，与十数帖，因得男而甚快。后遂以此方随母之形色性禀，参以时令加减与之，
无不应者。因名其方曰大达生散。
阳气汇聚于头部，因此面部是阳中之阳。鼻子位于面部的中央，阳明经起于鼻旁（迎香穴），全身运行的血液到达面部和鼻子时，都属于极其清纯精微的血液。酒性善于运行且喜好上升，性质大热且具有猛烈急迫的毒性。长期饮酒的人，酒气熏蒸面部和鼻子，使得到达这里的血液变得极热；热血遇到寒冷，被阴气郁结包裹，导致污浊凝结，气血停滞不行，所以颜色自然会先变为紫色，继而变为黑色。必须使用药物化解停滞的瘀血使其流动，滋生新的血液以便运化，疾病才能痊愈。我为此配制了酒制的四物汤，加入炒白术、茯苓、陈皮、生甘草、酒制红花，用生姜煎煮，调服五灵脂粉末饮用。对于气虚者，加入酒制黄芪。没有不奏效的。
阳施放精气，阴接受变化，胎孕才能形成。如果血气虚损，不足以滋养胎儿，胎儿就会自然流产。或者因为劳累、愤怒导致情志受伤，内火随之发动，也能导致堕胎。推究其根本原因，都在于热。火能消蚀万物，这是造化的自然规律，《诸病源候论》却说是风冷伤害子宫导致堕胎，这是没有掌握病情本质的说法。
我见到贾家的妇女，只要怀孕到三个月左右必然流产。诊察她的脉象，左手脉大而无力，重按则涩，知道她是血少。因为她正值年轻，我只补益中气，使血液自然充盈荣养。当时正值初夏，教导她用浓煎的白术汤送服一钱黄芩末，服用三四十帖后，便得以保全胎儿并顺利生产。由此思考，因内热兼体虚而导致的流产，在情理上占多数。关于热和虚，应当区分轻重程度。希望以好生之德为务的医生，千万不要轻视这一点。
世间的难产患者，往往出现在心情郁闷、安逸享乐的人身上，也就是富贵奉养的家庭。如果是贫贱辛苦劳作的人，却没有这种情况。医书中只有“瘦胎饮”这一种论述，而这个方剂是为湖阳公主制定的，确实不是最完善的言论。为什么呢？有了这个方子，难产的情况依然如故。我的族妹深受难产之苦，后来再次怀孕，就设法终止妊娠，我很怜悯她。观察她形体肥胖但勤于女红针线活，构思了十天，忽然领悟道：这正好与湖阳公主的情况相反。那些奉养优厚的人，她们的体质之气必然充实，消耗其壅实之气使其平和，所以容易生产。现在看她形体肥胖，知道她气虚，久坐不动说明气机不运，因而气更加虚弱。久坐导致胞胎因为母亲的气不能自行运转而难产。应当补益母亲的气，那么孩子健壮就容易生产。当时她怀孕到五六个月，于是我在《大全方》的紫苏饮基础上加入补气药，给她服用十几帖，结果顺利生下男孩，非常高兴。后来便根据母亲的形色性格禀赋，参考时令进行加减变化使用这个方子，没有不奏效的。因此将方剂命名为“大达生散”。
Yang Qi gathers in the head; therefore, the face is "Yang within Yang." The nose is located in the center of the face, and the Yangming Meridian (Stomach Channel) originates near the nose. When blood circulates throughout the body to reach the face and nose, it becomes extremely pure and refined blood. Wine has a nature that promotes circulation and tends to ascend; it is intensely hot and possesses severe, urgent toxicity. In people who drink excessively, wine fumes steam the face and nose, making the blood reaching these areas extremely hot. When this hot blood encounters cold, it is constrained by Yin Qi, leading to turbid coagulation and stagnation. Consequently, the color naturally turns purple first, then black. Treatment must employ methods to resolve stagnant blood to restore flow and generate new blood for transformation; only then can the disease be cured. I prepared Siwu Tang (Four Substances Decoction) processed with wine, adding stir-fried Baizhu (Atractylodis Rhizoma), Fuling (Poria), Chenpi (Citri Reticulatae Pericarpium), Sheng Gancao (Glycyrrhizae Radix et Rhizoma), and Jiu Honghua (Carthami Flos processed with wine). It was decocted with Shengjiang (Zingiberis Rhizoma Recens) and taken with Wulingzhi powder (Trogopterori Faeces). For those with weak Qi, Jiuhuangqi (Astragali Radix processed with wine) was added. There were no failures in efficacy.
Yang imparts essence, and Yin undergoes transformation, thereby forming conception. If Blood and Qi are deficient and insufficient to nourish the fetus, spontaneous abortion occurs. Alternatively, labor or anger may injure the emotions, causing internal Fire to flare up, which can also lead to miscarriage. Tracing the root cause, all stem from Heat. Fire consumes matter, which is the natural law of creation. However, *Bingyuan* (Source of Diseases) attributes miscarriage to Wind-Cold injuring the Zi Zang (Uterus); this fails to grasp the true nature of the condition.
I observed a woman surnamed Jia who invariably suffered miscarriage around three months of gestation. Her pulse was large and powerless on the left side, and choppy upon heavy pressure, indicating Blood deficiency. Since she was young, I solely tonified Middle Qi to allow Blood to naturally flourish. At that time, it was early summer. I instructed her to take one Qian of Huangqin (Scutellariae Radix) powder with strongly brewed Baizhu Tang (Atractylodis Macrocephalae Decoction). After taking thirty to forty doses, she successfully carried the pregnancy to term. Reflecting on this, miscarriages due to internal Heat combined with deficiency are logically more common. Regarding Heat and Deficiency, their severity must be distinguished. Physicians dedicated to preserving life should not overlook this.
Difficult labor often occurs in individuals who are depressed and sedentary, typically those from wealthy families living in luxury. It is rarely seen among the poor and hardworking. Medical texts only mention "Shoutai Yin" (Fetus-Thinning Drink), but this formula was created for Princess Huyang and is indeed not the ultimate solution. Why? Even with this formula, difficult labor persists. My clan sister suffered greatly from difficult labor; upon subsequent pregnancies, she would terminate them, which deeply pitied me. Observing that she was obese yet diligent in needlework, after pondering for ten days, I suddenly realized: This situation is exactly opposite to that of Princess Huyang. Those living in luxury have solid Qi; consuming excess Qi to bring it to balance facilitates easy delivery. Now, seeing her obesity indicates Qi deficiency; prolonged sitting indicates stagnant Qi movement, further weakening Qi. Prolonged sitting causes the fetus to fail to descend because the mother's Qi cannot propel it. One must tonify the mother's Qi so the child becomes robust and delivery is easy. When she was five to six months pregnant, I modified Zisu Yin (Perillae Decoction) from *Daquan Fang* by adding Qi-tonifying herbs and administered over ten doses. She subsequently delivered a healthy boy with great relief. Thereafter, I adjusted this formula based on each mother's physique, appearance, temperament, and seasonal changes, achieving consistent success. Thus, I named the formula "Da Dasheng San" (Great Facilitator of Birth Powder).
