臌胀病有实证和虚证两种。实证，腹部按压时坚硬且疼痛；虚证，腹部按压时不坚硬也不疼痛。实证，适宜用泻下法、消积法治疗，随后再予以补益；虚证，适宜用温阳法、升提法治疗，以补益为关键。早晨症状缓解而傍晚加重的是血虚；傍晚症状缓解而早晨加重的是气虚；白天黑夜都加重的是气血俱虚。臌胀又叫做蛊胀，就是所说的单腹胀。（详细情况在《格致余论》中记载。）治疗方法以大补中气为主，兼以行湿，这是脾虚非常严重的表现，必须远离音乐娱乐，断绝浓腻厚味的食物。有气虚的，用大剂量的参、术，佐以陈皮、茯苓、黄芩、苍术之类；有血虚的，以四物汤为主，随证加减。实证兼人体质壮盛的，或许可以用攻下药，大便通畅后立即用药物收拾残局，以白术为主。气虚导致的中满，用四君子汤加川芎、当归、芍药、黄连、陈皮、厚朴、生甘草。胃虚导致的腹胀，用调中汤：人参、白术、陈皮、甘草、半夏、厚朴、生姜。腹胀挟带虚证的，用分消丸治疗。寒邪导致的腹胀挟带虚证的，用分消汤治疗。寒胀，用沉香尊重丸治疗。腹胀挟带内伤虚证的，用木香顺气汤并服沉香交泰丸。伤寒、痞满、燥实四种证候，且人体质壮盛的，或者杂病腹满类似这四种证候的，用大承气汤。太阴病，出现腹胀满，四肢肿，或全身肿，胸中痞塞，不想吃东西，小便少，大便难或溏泄，或者脾胀容易呃逆，大满体重，服用索矩三和汤。脾湿导致的腹胀满，面色黄，小便涩滞，用胃苓汤。下焦虚导致腹胀气上逆，用四物汤加人参、陈皮、木通、甘草、连翘；有食积的，吞服保和丸。饮酒人腹胀，小便混浊，夜间发作足肿，用桂苓甘露饮加人参。甘葛、藿香、木香。腹胀感觉不到满闷，是吃肉多导致的，用黄连（一两研末）阿魏（半两醋浸）研成糊状，做成丸药，同温中丸用白术汤送下。吃肉多导致腹胀，用三补丸起料，加香附、下甲，做成炊饼丸服用。厚朴治疗腹胀，因为它的味道辛散，必须用姜炮制。一种说法是：胀病必须用参、[缺字]、白术大剂量补脾，那么气自然会自动运行，白术又是君主之药，必须搭配厚朴来宽满。一个人气弱腹部膨隆浮肿，用人参、当归、茯苓、芍药各一钱，白术二钱，川芎七分半，陈皮、腹皮、木通、厚朴、海金沙各五分，紫苏梗、木香各三分，数服后浮肿尽去。其余头面未消，这是阳明气虚，所以难以消退，再用白术、茯苓。一个妇人，腹部长期虚胀单胀，因为气馁不能运化，只是面部肿手足，或者肿气上行，阳分来应，还可以治疗，以参、术、芎、归为主，佐以白芍药的酸敛作用收敛胀气，滑石燥湿兼利水，大腹皮敛气，紫苏梗、莱菔子、陈皮泄满，海金沙、木通利水，木香营运，生甘草调和诸药。一个妇人，气虚单胀面带肿，用参、术、茯苓、厚朴、大腹皮、芎归、白芍、生甘草、滑石。一个人嗜酒，患疟疾半年，患胀腹如蜘蛛；一个人嗜酒，便血后患胀，色黑而腹大形如鬼状（都见于《医要》）。以上两种情况，一种补其气，一种补其血，其余药物大体相出入，都获得了安宁。
Distension and fullness of the abdomen (Gu Zhang) presents as either excess or deficiency. In excess patterns, palpation reveals hardness and pain; in deficiency patterns, palpation reveals neither hardness nor pain. For excess patterns, purgative methods (Xia Fa) and reduction methods (Xiao Fa) are indicated, followed by tonification; for deficiency patterns, warming (Wen Zhi) and ascending (Sheng Zhi) methods are indicated, with tonification being paramount. If symptoms ease in the morning but worsen in the evening, it indicates Blood Deficiency (Xue Xu); if they ease in the evening but worsen in the morning, it indicates Qi Deficiency (Qi Xu); if they are urgent day and night, it indicates combined Qi and Blood Deficiency (Qi Xue Ju Xu). Distension and fullness is also known as Gu distension, referring to what is called "single abdominal distension" (Dan Fu Zhang). (Details can be found in *Ge Zhi Yu Lun*.) The treatment principle focuses on greatly tonifying Middle Qi (Zhong Qi) while promoting dampness resolution. This represents severe Spleen Deficiency (Pi Xu), requiring avoidance of music/entertainment and rich/greasy foods. In cases of Qi Deficiency, large doses of Ginseng (Renshen) and Atractylodes Macrocephala Rhizome (Baizhu) are used, assisted by Tangerine Peel (Chenpi), Poria (Fuling), Scutellaria Root (Huangqin), and Atractylodes Lancea Rhizome (Cangzhu). In cases of Blood Deficiency, Four Substances Decoction (Sì Wù Tāng) is the main formula, modified according to symptoms. If excess patterns accompany a robust constitution, attacking medicines may be used, but once bowel movements occur, recovery should be managed primarily with Atractylodes Macrocephala Rhizome (Baizhu). For middle-fullness due to Qi Deficiency, Four Gentlemen Decoction (Sì Jūn Zǐ Tāng) is added with Ligusticum Chuanxiong Rhizome (Chuān Xiōng), Angelica Sinensis Radix (Dāngguī), Peony Root (Shaoyao), Coptis Rhizome (Huánglián), Tangerine Peel (Chén pí), Magnolia Bark (Hòupò), and Licorice Root (Gāncǎo - raw). For stomach-deficiency abdominal distension, Regulate the Middle Decoction (Tiáo Zhōng Tāng) is used: Ginseng (Rénshēn), Atractylodes Macrocephala Rhizome (Báizhú), Tangerine Peel (Chénpí), Licorice Root (Gāncǎo), Pinellia Tuber (Bànbxià), Magnolia Bark (Hòupò), and Fresh Ginger (Shēngjiāng). For abdominal distension complicated by deficiency, Divide and Eliminate Pill (Fēn Xiāo Wán) is used. For cold-type abdominal distension complicated by deficiency, Divide and Eliminate Decoction (Fēn Xiāo Tāng) is used. For cold distension, Agastache Respecting Pill (Chénxiāng Zūnzhòng Wán) is used. For abdominal distension complicated by internal injury and deficiency patterns, Wood Fragrance Smooths Qi Decoction (Mùxiāng Shùnqì Tāng) and Agastache Harmonizes Yin-Yang Pill (Chénxiāng Jiāotài Wán) are used. For Taiyang Cold Damage (Shānghán), Pi-Man (Pihou), Dryness-Excess (Zàoshí) syndromes, in patients with robust constitutions, or miscellaneous diseases presenting with abdominal fullness resembling these four syndromes, Major Order the Yang Decoction (Dà Chéngqì Tāng) is used. For Taiyin Disease (Tàiyīn Bìng), presenting with abdominal fullness, swelling of the four limbs, or whole-body swelling, chest oppression, anorexia, oliguria, difficult or loose stools, or Spleen distension with frequent hiccups, great fullness, and heavy body, Suoju Sanhe Decoction (Suǒjǔ Sānhé Tāng) is administered. For Spleen-Dampness causing abdominal fullness, yellow complexion, and dysuria, Stomach-Poria Decoction (Wèilíng Tāng) is used. For lower-jiao deficiency causing abdominal distension with Qi rebellion, Four Substances Decoction (Sì Wù Tāng) is added with Ginseng (Rénshēn), Tangerine Peel (Chénpí), Akebia Stem (Mùtōng), Licorice Root (Gāncǎo), and Forsythia Fruit (Liánqiào); if there is food stagnation, Harmony Preserving Pill (Bǎohé Wán) is swallowed. For drinkers with abdominal distension, turbid urine, and nocturnal foot swelling, Cinnamon Twig and Poria Decoction (Guìlíng Gānlù Yǐn) is used with Ginseng (Rénshēn), along with Kudzu Root (Gāngě), Patchouli Herb (Huòxiāng), and Aucklandia Root (Mùxiāng). For abdominal distension where fullness is not perceived, caused by excessive meat consumption, use Coptis Rhizome (Huánglián - 1 liang powdered) and Asafoetida (Āwèi - 0.5 liang vinegar-soaked), ground into a paste, made into pills, and taken with Baizhu Decoction alongside Warm the Middle Pill (Wēnzhōng Wán). For abdominal distension from excessive meat consumption, Three Tonics Pill (Sān Bǔ Wán) is used as the base, adding Cyperus Rhizome (Xiāngfù) and Oyster Shell (Xiàjiǎ), formed into steamed dough pills. Magnolia Bark (Hòupò) treats abdominal distension due to its pungent flavor; it must be processed with ginger. One view states that distension diseases require large doses of Ginseng (Rénshēn), [Missing Character], and Atractylodes Macrocephala Rhizome (Báizhú) to tonify the Spleen, allowing Qi to move spontaneously; since Baizhu is the sovereign herb, it must be paired with Hòupò to relieve fullness. For a person with weak Qi, abdominal bloating, and edema, use Ginseng (Rénshēn), Angelica Sinensis Radix (Dāngguī), Poria (Fúlín), and Peony Root (Sháoyào) each 1 qian, Atractylodes Macrocephala Rhizome (Báizhú) 2 qian, Ligusticum Chuanxiong Rhizome (Chuānxiōng) 0.75 qian, Tangerine Peel (Chénpí), Areca Seed (Fúpí), Akebia Stem (Mùtōng), Magnolia Bark (Hòupò), and Gold Sand Grass (Hǎijīnshā) each 0.5 qian, Perilla Stem (Zǐsū Gěng) and Aucklandia Root (Mùxiāng) each 0.3 qian. After several doses, edema disappears. If head and face swelling remain, this indicates Yangming Qi Deficiency, making it hard to resolve; use Baizhu and Fuling again. For a woman with long-standing deficiency-type single abdominal distension, due to depleted Qi failing to transport, presenting only with facial and extremity swelling, or Qi swelling upward responding to Yang aspects, which is treatable, use Ginseng (Rénshēn), Atractylodes Macrocephala Rhizome (Báizhú), Ligusticum Chuanxiong Rhizome (Chuānxiōng), and Angelica Sinensis Radix (Dāngguī) as the main herbs, assisted by White Peony Root (Bái Sháoyào) for its sour astringency to constrain distension, Talcum (Huáshí) to dry dampness and promote urination, Areca Seed (Dàfúpí) to constrain Qi, Perilla Stem (Zǐsū Gěng), Radish Seed (Láifuzǐ), and Tangerine Peel (Chénpí) to drain fullness, Gold Sand Grass (Hǎijīnshā) and Akebia Stem (Mùtōng) to promote urination, Aucklandia Root (Mùxiāng) to circulate Qi, and Raw Licorice Root (Shēng Gāncǎo) to harmonize the herbs. For a woman with Qi-deficiency single distension and facial swelling, use Ginseng (Rénshēn), Atractylodes Macrocephala Rhizome (Báizhú), Poria (Fúlín), Magnolia Bark (Hòupò), Areca Seed (Dàfúpí), Ligusticum Chuanxiong Rhizome (Chuānxiōng), Angelica Sinensis Radix (Dāngguī), White Peony Root (Bái Sháoyào), Raw Licorice Root (Shēng Gāncǎo), and Talcum (Huáshí). For a person addicted to alcohol who suffered malaria for half a year and developed abdominal distension like a spider; and another person addicted to alcohol who developed distension after hematochezia, with black complexion and a giant abdomen resembling a ghost (both seen in *Yi Yao*). For the above two cases, one tonifies Qi, the other tonifies Blood; the remaining herbs vary slightly, yet all achieved peace/recovery.
