留饮者，留而不去也。心下痞满，作哕头眩，芎归桂朴汤主之。
芎归桂朴汤（自制）
川芎（八分） 当归（二钱） 桂枝（八分） 浓朴（一钱） 枳实（一
钱） 广皮（一钱） 半夏（一钱五分） 茯苓（三钱） 天麻（六分） 菊花（二钱）
姜（三片）
芎、归肝家血药也，姜、桂开太阳也，枳、朴、橘、半、茯苓消痰湿也，天麻、菊花佐芎、归
而上行也。诸方皆降，而此独升，独用血药，以肝为寒饮侵犯，而血行不畅也。祖怡注。
伏饮者，伏而不出也。痰满喘咳吐，发则寒热，背痛腰疼，其人振振身 剧，此乃三阳之气为
阴邪遏抑，郁而不舒，桂枝半夏汤主之。
桂枝半夏汤（自制）
桂枝（八分） 半夏（一钱五分） 茯苓（三钱） 广皮（一钱） 白术（二钱） 芥子
（一钱） 浓朴（一钱） 紫苏（一钱） 贝母（二钱） 甘草（四分） 姜（三
片）
此方用苓桂术甘合二陈。再以芥子去皮里膜外之水，得姜、桂而温通之力更大。紫苏以佐姜、
桂，贝母以佐半夏，浓朴以佐广皮。治伏饮方，亦可以之治疟。盖无痰不成疟，见症发寒发热，振
振身 剧，岂不是痰饮伏而不出，有转疟之兆乎！饮证六方，每方皆有二陈，五方皆有桂、姜，三
方皆有白术，亦可见治饮用药之大法矣。祖怡注。
留饮，是指水饮停留体内而不去除。症状表现为胃脘部痞塞胀满，恶心干呕，头晕目眩，治疗以芎归桂朴汤为主方。
芎归桂朴汤（自制方）
川芎（八分） 当归（二钱） 桂枝（八分） 浓朴（一钱） 枳实（一钱） 广皮（一钱） 半夏（一钱五分） 茯苓（三钱） 天麻（六分） 菊花（二钱） 生姜（三片）
川芎、当归是入肝经的血分药；生姜、桂枝能开通太阳经气；枳实、浓朴、陈皮、半夏、茯苓能消除痰湿；天麻、菊花辅助川芎、当归使药力上行。其他方剂多主降，唯独此方主升，单独使用血分药，是因为寒邪水饮侵犯肝脏，导致血液运行不畅。这是祖怡的注解。
伏饮，是指水饮潜伏于体内而不能排出。症状表现为痰多胸闷、气喘咳嗽、吐痰，发作时伴有恶寒发热，背痛腰痛，身体剧烈颤抖动摇，这是因为三阳经之气被阴邪遏制抑制，郁结而不能舒展，治疗以桂枝半夏汤为主方。
桂枝半夏汤（自制方）
桂枝（八分） 半夏（一钱五分） 茯苓（三钱） 广皮（一钱） 白术（二钱） 芥子（一钱） 浓朴（一钱） 紫苏（一钱） 贝母（二钱） 甘草（四分） 生姜（三片）
此方使用了苓桂术甘汤合二陈汤。再加入芥子以去除皮里膜外的水饮，配合生姜、桂枝，温通的力量更大。紫苏辅助生姜、桂枝，贝母辅助半夏，浓朴辅助广皮。治疗伏饮的方剂，也可以用来治疗疟疾。大概没有痰就不会形成疟疾，见到发作时恶寒发热、身体剧烈颤抖的症状，这难道不是痰饮潜伏体内不能排出，有转化为疟疾的征兆吗！治疗饮证的六个方剂中，每个方剂都含有二陈汤的成分，五个方剂都含有桂枝和生姜，三个方剂都含有白术，这也可见治疗饮证用药的大法了。这是祖怡的注解。
Liu Yin (Retained Fluid) refers to fluid retention that remains in the body and is not expelled. The symptoms include epigastric fullness and obstruction, hiccups, and dizziness. It is primarily treated with Xiong Gui Gui Po Tang (Sichuan Lovage and Angelica Cinnamon and Magnolia Bark Decoction).
Xiong Gui Gui Po Tang (Self-made Formula)
Chuanxiong Rhizoma (8 fen) Danggui Radix (2 qian) Guizhi Ramulus Cinnamomi (8 fen) Houpo Cortex Magnoliae Officinalis (1 qian) Zhishi Fructus Aurantii Immaturus (1 qian) Chenpi Pericarpium Citri Reticulatae (1 qian) Banxia Rhizoma Pinelliae Preparatum (1.5 qian) Fuling Sclerotium Poriae (3 qian) Tianma Rhizoma Gastrodiae (6 fen) Juhua Flos Chrysanthemi (2 qian) Shengjiang Rhizoma Zingiberis Recens (3 slices)
Chuanxiong and Danggui are blood-invigorating herbs entering the Liver channel; Shengjiang and Guizhi open the Taiyang channel; Zhishi, Houpo, Chenpi, Banxia, and Fuling eliminate phlegm and dampness; Tianma and Juhua assist Chuanxiong and Danggui in ascending the medicinal power. While most formulas direct qi downward, this one alone directs it upward. It uniquely employs blood-invigorating herbs because cold-fluid invasion affects the Liver, causing poor blood circulation. This is an annotation by Zu Yi.
Fu Yin (Hidden Fluid) refers to fluid hidden within the body that cannot be discharged. Symptoms include excessive phlegm, chest fullness, wheezing, coughing, and expectoration. Upon attack, there are alternating chills and fever, back pain, waist pain, and severe trembling of the body. This occurs because the Qi of the Three Yang channels is suppressed by Yin pathogens, leading to stagnation and failure to diffuse smoothly. It is primarily treated with Guizhi Banxia Tang (Cinnamon Twig and Pinellia Decoction).
Guizhi Banxia Tang (Self-made Formula)
Guizhi Ramulus Cinnamomi (8 fen) Banxia Rhizoma Pinelliae Preparatum (1.5 qian) Fuling Sclerotium Poriae (3 qian) Chenpi Pericarpium Citri Reticulatae (1 qian) Baizhu Rhizoma Atractylodis Macrocephalae (2 qian) Jiezi Semen Sinapis (1 qian) Houpo Cortex Magnoliae Officinalis (1 qian) Zisu Folium Perillae (1 qian) Beimu Bulbus Fritillariae Cirrhosae (2 qian) Gancao Radix Glycyrrhizae (4 fen) Shengjiang Rhizoma Zingiberis Recens (3 slices)
This formula combines Ling Gui Zhu Gan Tang (Poria, Cinnamon Twig, Atractylodes, and Licorice Decoction) with Er Chen Tang (Two-Cured Decoction). Then, Jiezi is added to remove water from beneath the skin and between membranes. Combined with Shengjiang and Guizhi, its warming and unblocking power is greatly enhanced. Zisu assists Shengjiang and Guizhi; Beimu assists Banxia; Houpo assists Chenpi. Formulas for treating Fu Yin can also be used to treat Nue Ji (Malaria). Generally, without phlegm, malaria does not form. Seeing symptoms such as alternating chills and fever, and severe bodily trembling, is it not a sign that hidden fluid/phlegm fails to discharge and has signs of transforming into malaria? Among the six formulas for treating Yin syndromes, each contains components of Er Chen Tang; five contain Guizhi and Shengjiang; three contain Baizhu. This reveals the major principles of medication for treating Yin syndromes. This is an annotation by Zu Yi.
