14.邪气传里必先胸, 由胸及胁少阳经, 太阳脉浮惟胸满, 过经不解
有阳明. 干呕潮热胸胁满, 大柴加消两解行. 心腹引胁硬满痛, 干呕
尿秘十枣攻.
【注】邪气传里必先自胸, 若脉浮惟胸满而不及胁者, 仍属太阳表分
也,宜麻黄汤. 因胸及胁而皆满者, 属少阳经也, 宜小柴胡汤. 若十
余日不解, 而胸胁满, 兼干呕潮热者, 是少阳兼有阳明也, 宜大柴胡
汤加芒硝两解之. 若表己解, 心下及腹引胁, 满硬而痛, 干呕小便不
利者, 是停饮内实也, 宜十枣汤攻之.
15.呕病因何属少阳? 表入里拒故为殃, 太阳之呕表不解, 食谷欲呕
在胃阳, 太阴有吐而无呕, 厥阴涎沫吐蛔长, 少阴呕痢有水气, 饮呕
相因是水乡.
【注】呕病诸经皆有, 因何属少阳也? 因表邪入里, 里气拒格, 上逆
作呕, 故为殃属少阳也, 宜小柴胡汤. 心下硬而烦, 或不大便, 宜大
柴胡汤. 表不解之呕属太阳也, 宜柴桂汤. 食谷欲呕, 属胃阳；胃阳
,阳明也. 属中寒, 宜吴茱萸汤; 得汤更呕属表热, 宜葛根加半夏汤
.呕吐涎沫, 或呕吐蛔, 属厥阴也. 宜吴茱萸汤; 吐蛔者, 宜乌梅丸
.呕而下痢, 是有水气, 属少阴也, 宜真武汤. 饮而呕, 呕而饮, 饮
呕相因不已, 是停水也, 宜五苓散.
14. 邪气传入体内必然先经过胸部，随后由胸波及胁部，涉及少阳经。若太阳病脉象浮仅表现为胸部胀满，而病程超过本经期限仍未解除，则可能兼有阳明病。出现干呕、潮热、胸胁胀满的症状，应使用大柴胡汤加芒硝，以同时解表攻里。若心腹部牵引胁肋部出现硬满疼痛，伴有干呕、小便不通畅，应用十枣汤进行攻逐水饮治疗。
【注】邪气传入体内必然先从胸部开始。如果脉象浮仅见胸部胀满而未波及胁部，说明病邪仍在太阳经的表分，适宜使用麻黄汤。如果病变由胸部波及胁部且两者皆胀满，则属于少阳经病证，适宜使用小柴胡汤。若十余日病情未解，出现胸胁胀满，并伴有干呕、潮热等症状，这是少阳病兼有阳明病的表现，适宜使用大柴胡汤加芒硝，以双解少阳与阳明之邪。若表证已解，但心下及腹部牵引胁肋部，出现胀满、坚硬且疼痛，伴有干呕、小便不利，这是水饮停聚且内有实邪的表现，适宜使用十枣汤进行攻逐。
15. 呕吐病因为何归属于少阳？因表邪入里，正气拒格于内，导致气机上逆作呕，故为祸患而归属于少阳。太阳病的呕吐因表证未解所致；进食后欲呕吐，多属胃阳不足（此处指中焦虚寒或胃气上逆）；太阴病仅有吐而无呕；厥阴病常伴有涎沫呕吐或蛔虫吐出；少阴病呕吐伴下痢，是有水气存在；饮水与呕吐互为因果，是停水（水饮内停）的表现。
【注】呕吐一症各经均可出现，为何特指归属于少阳？这是因为表邪入里，里气抗拒格拒，气机上逆而作呕，故为祸患归属于少阳，适宜使用小柴胡汤。若心下硬满且心烦，或者不大便，适宜使用大柴胡汤。因表证未解引起的呕吐属于太阳病，适宜使用柴桂汤（柴胡桂枝汤）。进食后欲呕吐，属于胃阳问题（此处原文语境倾向于阳明或中焦寒热错杂/虚寒，注中进一步辨析）：若属中焦虚寒，适宜使用吴茱萸汤；若服用吴茱萸汤后呕吐加剧，则属表热，适宜使用葛根加半夏汤。呕吐涎沫，或呕吐蛔虫，属于厥阴病，适宜使用吴茱萸汤；若吐出蛔虫，适宜使用乌梅丸。呕吐且伴有下痢，是有水气存在，属于少阴病，适宜使用真武汤。饮水后呕吐，呕吐后又想饮水，饮与呕相互关联不止，这是水饮停聚的表现，适宜使用五苓散。
14. Pathogenic factors entering the interior must first affect the chest, then spread from the chest to the hypochondrium, involving the Shaoyang (Lesser Yang) channel. If the Taiyang (Greater Yang) disease presents with a floating pulse and only chest fullness, but the disease persists beyond its proper period, it may involve the Yangming (Yang Brightness) disease. Symptoms such as dry retching, tidal fever, and chest-hypochondriac fullness should be treated with Da Chai Hu Tang (Major Bupleurum Decoction) plus Mangxiao (Natrii Sulfas) to resolve both exterior and interior pathogens simultaneously. If there is hard, full pain in the heart and abdomen radiating to the hypochondrium, accompanied by dry retching and urinary retention, Shizao Tang (Ten Jujube Decoction) should be used to purge fluid retention.
[Annotation] Pathogenic factors entering the interior must start from the chest. If the pulse is floating and there is only chest fullness without involvement of the hypochondrium, the pathogen still resides in the exterior aspect of the Taiyang channel, and Mahuang Tang (Ephedra Decoction) is appropriate. If the condition spreads from the chest to the hypochondrium causing fullness in both areas, it belongs to the Shaoyang channel, and Xiaochaihu Tang (Minor Bupleurum Decoction) is appropriate. If the disease remains unresolved for more than ten days, presenting with chest-hypochondriac fullness, dry retching, and tidal fever, this indicates a combination of Shaoyang and Yangming diseases; Da Chaihu Tang (Major Bupleurum Decoction) plus Mangxiao (Natrii Sulfas) should be used to resolve both aspects. If the exterior syndrome has resolved, but there is hard, painful fullness in the epigastrium and abdomen radiating to the hypochondrium, accompanied by dry retching and difficulty urinating, this indicates internal fluid retention and excess; Shizao Tang (Ten Jujube Decoction) should be used to purge it.
15. Why does vomiting belong to the Shaoyang? It is because pathogenic factors enter from the exterior into the interior, where the interior Qi resists and blocks, causing upward rebellion and vomiting, thus becoming a calamity belonging to the Shaoyang. Vomiting due to Taiyang disease results from an unresolved exterior syndrome; desire to vomit after eating relates to Stomach Yang; the Taiyin disease involves spitting but not retching; the Jueyin (Terminal Yin) disease often features vomiting of saliva/phlegm or roundworms; Shaoyin (Lesser Yin) vomiting with diarrhea indicates the presence of water Qi; drinking and vomiting reciprocally indicate fluid retention.
[Annotation] Vomiting can occur in all channels; why is it specifically attributed to Shaoyang? Because pathogenic factors enter from the exterior into the interior, the interior Qi resists and blocks, causing upward rebellion and vomiting, thus becoming a calamity attributed to Shaoyang, and Xiaochaihu Tang (Minor Bupleurum Decoction) is appropriate. If there is hardness and irritability in the epigastrium, or constipation, Da Chaihu Tang (Major Bupleurum Decoction) is appropriate. Vomiting due to an unresolved exterior syndrome belongs to Taiyang, and Chaigui Tang (Bupleurum and Cinnamon Twig Decoction) is appropriate. Desire to vomit after eating relates to Stomach Yang: if it belongs to Middle Jiao cold, Wuzhuyu Tang (Evodia Decoction) is appropriate; if vomiting worsens after taking the decoction, it belongs to exterior heat, and Gegen Banxia Tang (Pueraria and Pinellia Decoction) is appropriate. Vomiting of saliva/phlegm or vomiting of roundworms belongs to Jueyin disease; Wuzhuyu Tang (Evodia Decoction) is appropriate; if roundworms are vomited, Wu Mei Wan (Mume Pill) is appropriate. Vomiting accompanied by diarrhea indicates the presence of water Qi and belongs to Shaoyin disease; Zhenwu Tang (True Warrior Decoction) is appropriate. Drinking followed by vomiting, or vomiting followed by thirst for drinking, where drinking and vomiting reciprocally persist, indicates fluid retention; Wuling San (Five-Ingredient Powder with Poria) is appropriate.
