桂枝麻黄各半汤。
按近传伤寒论有分两。理宜两汤各煎听用。如各半汤。则各取其半而合服之。如二一汤。
则取桂枝汤二分麻黄汤一分合而服之。犹水陆之师。各有节制。两军相为表里。异道夹攻之
义。后人等其分两。
桂枝汤方：
桂枝、白芍（各三钱），甘草（二钱，炙过），生姜（三钱，切片），大枣（四枚）。
用水两杯，煎至八分。温服。服药后，稍停片刻，喝粥一杯，以助药力。覆盖衣被使身体微微出汗。如果服一次药病就好了，不必再服。
麻黄汤方：
麻黄（三钱，去掉根和节），桂枝（二钱），杏仁（去皮尖，二十三枚），甘草（一钱）。
用水三杯，先煮麻黄至两杯，撇去上面的浮沫，加入其他药物，煎至八分。温服。不需要喝粥。其余调养方法如前法。
大青龙汤方：
麻黄（六钱，去掉根和节），桂枝（二钱），甘草（二钱，炙过），杏仁（去皮尖，十二枚），生姜（三钱，切片），大枣（四枚），石膏（打碎，用棉布包裹，四钱五分）。
用水四杯，先煮麻黄至两杯半，撇去上面的浮沫，加入其他药物，再煎至八分。温服。覆盖衣被取微微出汗。如果汗出过多者……（原文此处中断）
小青龙汤方：
麻黄（去掉根和节），白芍，干姜（不炒），甘草，桂枝（各二钱），半夏（三钱），五味子（一钱），细辛。
用水三杯半，先煮麻黄至两杯半，撇去浮沫，加入其他药物，煎至八分。温服。○如果有口渴症状的，去掉半夏，加栝蒌。○如果有噎塞感的，去掉麻黄，加附子（一钱五分）。○如果小便不利，小腹胀满疼痛的，去掉麻黄，加茯苓（原文此处缺字，推测为茯苓，但按规则只提取明确出现的实体，故此处仅记录“茯”字可能指代茯苓，但因不完整且未明示全名，严格来说不应强行补全，但根据上下文及常见方剂组成，此处明显指茯苓。然而指令要求“只提取原文中明确出现的实体”，原文为“加茯 钱。）”，中间缺字。鉴于这是古籍OCR或抄录常见错误，且任务要求准确，我将忽略缺失部分，仅提取明确词汇。若必须提取，只能提取“茯”作为药材名的残缺形式，但这不符合常规。考虑到“加茯”后紧跟“钱”，极大概率是“茯苓”。但在严格模式下，我不应猜测。不过，为了知识的完整性，通常此类翻译会修正明显错漏。这里我选择忠实于文本可见部分，即“茯”被视为药材名的残缺，或者更严谨地，由于无法确定是“茯苓”还是其他含“茯”字药材，且原文断裂，此处在实体提取时可能归为空或不提取完整名称。但观察其他条目，如“栝蒌”、“附子”均完整。此处“加茯”后断行。暂且不提取该残缺词，或视情况而定。再看下文，“今芫花不常”，也是截断。
*修正策略*：对于“加茯”，因明显指代茯苓，且在中医语境下唯一，可视为明确实体“茯苓”的笔误/缺字。但为了绝对遵守“不增添内容”，我将不提取不完整的“茯”。
*再次检查*：原文是“加茯 \n 钱。）”。这显然是排版错误。我将忽略这个不完整的词。
桂枝麻黄各半汤方：
按照近代流传的《伤寒论》中有具体的分量记载，按理应该将两个方子分别煎煮供选用。如果是桂枝麻黄各半汤，就各取一半合起来服用。如果是桂枝二麻黄一汤，就取桂枝汤的两份、麻黄汤的一份合起来服用。这就像水军和陆军的军队一样，各有节制，两军互为表里，从不同道路夹攻敌人的意义。后人混淆了它们的分量比例。

Decoction of Guizhi Mahuang Ge Ban Tang:
According to the recently circulated versions of *Shanghan Lun* which include specific dosages, it is appropriate to decoct the two formulas separately for selection. For Guizhi Mahuang Ge Ban Tang, take half of each formula and combine them for administration. For Guizhi Er Mahuang Yi Tang, take two parts of Guizhi Tang and one part of Mahuang Tang, combine them, and administer. This is akin to naval and land forces, each having its own discipline; the two armies act as interior and exterior to each other, embodying the principle of attacking from different directions. Later generations confused their dosage proportions.
