所谓阻者，经血既闭，痰水积于中，阻其脏气，不得宣通也。
《金匮》曰:妇人得平脉，阴脉小弱，其人渴不能食,无寒热，名妊娠。于法六十日，当有此证，设有医者治逆，却
一月，加吐下者，则绝之。（娄全善曰∶恶阻者，谓呕吐、恶心、头眩恶食、择食是也。绝之者，谓绝止医治，候其自安
也。尝治一二妊妇恶阻病，呕吐愈治愈逆，因思仲景绝之之旨，遂停药月余自安。大哉！圣人之道也。徐忠可曰∶其期
有未满六十日则胎未成，又加吐利，因医者以安胎为主，见而用条芩、砂仁之类，则脾胃实有受伤处，但当断绝病根为
主，不得泥安胎之说，故曰绝之。）
妇人所食谷味，化为血气，下为月水。凡妊娠之初，月水乍聚，一月为媒，二月为胚，三月为胎，成则男
女上食于母。然在三月相火化胎之候，未能上食于母，血气未用，五谷不化，中气壅实，其为郁滞、痰火、
秽恶之气尽冲于胃，所以恶心有阻也。其候心中愦闷，头眩，四肢懈惰，恶闻食气，多睡少起，酷嗜酸盐
果实者，乃肝肾不足，引以自救也。
凡孕二、三月间，妊妇禀受怯弱，便有阻病，呕逆不食，或心烦闷，状如醉酒，肢体沉重，择食，
恶食，头目昏眩，此乃气血积聚以养胎元，其精血内郁，而秽腐之气上攻于胃，是以呕逆
不能纳食；血既养胎，心失所荣，是以心虚烦闷。法当调血散郁，
用参、术、甘草补中气；桔红、紫苏、木香、生姜散郁气；茯苓、麦冬、黄芩、竹茹清热解烦，名参
桔饮，所谓胎前须顺气者此也。但胎前无寒，胎后无热，至于恶阻呕吐，尤多属热。然亦有因寒
而吐者，乃因病而非因恶阻也，不止则虚矣。当以人参干姜半夏丸主之，不可过用辛药。若吐甚
而愈止愈急者，用仲景法，停药月余自安矣。
《千金方》有半夏茯苓汤、茯苓丸，专治恶阻，比来少有服者，以半夏能动胎，胎初结，虑其辛燥
易散也，须姜汁炒以制其毒。凡恶阻非半夏不能止，故仲景用人参半夏干姜丸。罗谦甫用二陈去
陈皮、甘草，即名半夏茯苓汤。朱丹溪谓肥人多因痰，瘦人多因火，用二陈加减，并治胎前恶阻，
痰逆呕吐，心烦，头眩，恶食俱效。经云有故无殒是也。立斋曰∶半夏乃健脾气，化痰滞主药，
脾胃虚弱呕吐，或痰涎壅滞饮食少、胎不安，必用半夏茯苓汤，倍加白术安胎健脾。常用甚验也。恶阻兼
腰痛者，防胎堕下，尤宜二陈四物，加条芩、白术，和中理脾为主，不可升举。盖呕逆气
已上升，药再上升，则犯有升无降，上更实而下更虚，益促其堕矣。

The term "Zu" (Obstruction) refers to the situation where menstrual blood has ceased, phlegm and fluid accumulate in the middle, obstructing the Qi of the Zang organs, preventing its free circulation.
The *Jin Gui Yao Lue* states: When a woman presents with a normal pulse, but the Yin pulse (Chi position) is slightly weak, and she experiences thirst and inability to eat, without aversion to cold or fever, this is named Pregnancy. According to the method, around sixty days, this syndrome should appear. If a physician treats it incorrectly, delaying by a month and exacerbating vomiting and diarrhea, one should "Jue Zhi" (Stop treatment). (Lou Quanshan said: "E Zu" refers to vomiting, nausea, dizziness, food aversion, and selective eating. "Jue Zhi" means to cease medical intervention and wait for self-recovery. I once treated one or two pregnant women with E Zu; the more they were treated, the worse their vomiting became. Reflecting on Zhang Zhongjing's principle of "Jue Zhi," I stopped medication for over a month, and they recovered naturally. Great is the Way of the Sages! Xu Zhongke said: If the time is less than sixty days, the fetus is not yet formed, and vomiting/diarrhea occur. Because physicians focus on calming the fetus, using herbs like Huang Qin (Scutellaria Root) and Sha Ren (Amomum Fruit), the Spleen and Stomach may be injured. One should focus on eliminating the root cause rather than adhering strictly to fetal calming, hence "Jue Zhi.")
The food eaten by women transforms into Blood and Qi, flowing downward as menstruation. In early pregnancy, when menstruation suddenly stops, the first month is called "Mei," the second "Pei," and the third "Tai." Once formed, the male or female fetus nourishes itself from the mother. However, during the third month, when the Ministerial Fire transforms the fetus, the fetus cannot yet draw nutrition from the mother. The Blood and Qi are not yet heavily utilized, and the five grains are not fully digested. The Qi of the Middle Jiao becomes stagnant and full. All stagnation, Phlegm-Fire, and foul odors rush to the Stomach, causing nausea and obstruction. Symptoms include mental restlessness, dizziness, flaccidity of the four limbs, aversion to the smell of food, excessive sleep with little rising, and a strong craving for sour and salty fruits. This indicates insufficiency of the Liver and Kidney, drawing these flavors for self-rescue.
In the second and third months of pregnancy, if the pregnant woman has a weak constitution, she will suffer from E Zu disease: vomiting, inability to eat, mental irritability resembling drunkenness, heaviness of the limbs, selective eating, food aversion, and dizziness. This occurs because Blood and Qi accumulate to nourish the Fetal Origin. The essence and Blood stagnate internally, and foul/rotten Qi attacks the Stomach upward, causing vomiting and inability to accept food. Since Blood nourishes the fetus, the Heart loses nourishment, leading to Heart deficiency and mental irritability. The treatment method should regulate Blood and dissipate stagnation. Use Renshen (Ginseng Root), Baizhu (Atractylodes Rhizome), and Gancao (Licorice Root) to tonify Middle Qi; use Juhong (Tangerine Red Peel), Zisu (Perilla Leaf), Muxiang (Costus Root), and Shengjiang (Fresh Ginger) to disperse stagnant Qi; use Fuling (Poria), Maidong (Ophiopogon Tuber), Huang Qin (Scutellaria Root), and Zhuru (Bamboo Shavings) to clear heat and relieve irritability. This formula is named Shen Ju Yin (Ginseng and Tangerine Peel Decoction), illustrating the principle that "during pregnancy, Qi must be smoothed." Generally, there is no Cold before pregnancy and no Heat after pregnancy. However, E Zu vomiting mostly belongs to Heat. Yet, some vomiting is caused by Cold, which is due to illness rather than E Zu. If unchecked, it leads to deficiency. One should treat with Renshen Gan Jiang Ban Xia Wan (Ginseng, Dried Ginger, and Pinellia Pill) and avoid excessive use of acrid/warm herbs. If vomiting is severe and stopping it makes it more urgent, follow Zhang Zhongjing's method: stop medication for over a month, and it will settle naturally.
The *Qian Jin Fang* contains Ban Xia Fu Ling Tang (Pinellia and Poria Decoction) and Fu Ling Wan (Poria Pill), specifically treating E Zu. Recently, few people take them, fearing that Ban Xia (Pinellia Tuber) disturbs the fetus. Since the fetus is newly formed, its acrid-dry nature might scatter the fetus. It must be stir-fried with Jiang Zhi (Ginger Juice) to mitigate toxicity. E Zu cannot be stopped without Ban Xia, so Zhang Zhongjing used Renshen Ban Xia Gan Jiang Wan (Ginseng, Pinellia, and Dried Ginger Pill). Luo Qianfu used Er Chen Tang (Two-Cured Decoction) removing Chen Pi (Tangerine Peel) and Gancao (Licorice Root), naming it Ban Xia Fu Ling Tang. Zhu Danxi stated that fat people often have Phlegm, while thin people often have Fire. He used modified Er Chen Tang to treat pre-pregnancy E Zu, Phlegm-reversal vomiting, mental irritability, dizziness, and food aversion, all effectively. The Classic says, "If there is an existing pathogen, there will be no injury," which applies here. Xue Lizhai said: Ban Xia is the main herb for strengthening Spleen Qi and resolving Phlegm stagnation. For Spleen-Stomach weakness with vomiting, or Phlegm-saliva congestion with poor appetite and unstable fetus, Ban Xia Fu Ling Tang must be used, with doubled Baizhu (Atractylodes Rhizome) to calm the fetus and strengthen the Spleen. It is commonly very effective. For E Zu accompanied by lower back pain, to prevent miscarriage, Er Chen Tang combined with Si Wu Tang (Four-Substance Decoction) is especially suitable, adding Huang Qin (Scutellaria Root) and Baizhu (Atractylodes Rhizome), focusing on harmonizing the Middle and regulating the Spleen. Ascending herbs should be avoided. Since vomiting involves ascending Qi, using ascending drugs would violate the principle of "ascending only, descending never," making the Upper fuller and the Lower emptier, thereby hastening miscarriage.
