琥按上方。乃治肺胃烦热之剂。盖劳则气耗。而生烦热故也。今方家惟大青一味不见用。纲目云。其茎叶深青。
其性大寒其味苦甘。乃草药中之无毒者。医人不可以不知也。

疗伤寒病后男子阴易方。
薤（一大把。肘后方作蓝。即板蓝根也。叶可作靛。今处处种之。） 鼠粪（十四枚。 音加。雄鼠也。其粪两头
尖者是。）
上二味。以水五升。煮取二升。尽饮之温卧。汗出便愈。亦理劳复。
琥按薤味辛温。蓝味苦寒。亦各因其证而用之。（又疗交接劳复卵肿。腹中绞痛。便绝死。竹皮汤方此方又疗伤寒
病瘥。语言书疏。坐起行步劳复者。）
（一升）
上一味。以水三升。煮五六沸。绞去滓。顿服。立愈。
琥按上主疗云。交接劳复。乃女劳复。而非阴阳易也。劳复之证。有阴虚生内热者。此方可选而用之。
又疗阴阳易。
大青（四两） 甘草（二两，炙） 阿胶（二两，炒） 香豉（二两）
以上四味药。切碎，用水一斗煎煮，取汁三升。滤去药渣。每次温服一升，每日服用五六次，直到药力耗尽。再次煎制，常备有药汤。口渴时即可饮用。此方无毒，能清热止吐泻。适用于伤寒一二日，甚至长达十数日，病情危重，发汗后热势不退；或经吐下治疗后，热邪仍未清除者。对于止住严重的痢疾效果极佳。先煎煮大青和甘草，取汁四升，滤去药渣。加入阿胶和香豉，待阿胶完全溶化后，滤去豆渣。不要让香豉煮烂。应当预先浸泡阿胶使其溶解。
琥按：上方是治疗肺胃烦热的方剂。大概是因为劳累导致气耗散，从而产生烦热所致。如今医家很少使用大青这一味药。《本草纲目》记载：它的茎叶呈深青色，性大寒，味苦甘，是草药中无毒的一种。医生不可以不知道这一点。
又用于治疗伤寒病愈后。
葵子（二升） 粱米（一升）
以上两味药，合在一起煮成稀粥。饮用它，多多益善。出汗后即可立即痊愈。
琥按：上方是滑利肠胃兼和中气的方剂。大概是用葵子的甘寒之性来通利窍道，用粱米的甘凉之性来养胃。
治疗伤寒病后男子阴易的方子。
薤（一大把，《肘后方》作蓝，即板蓝根。叶子可制作靛蓝染料，现在到处都有种植。） 鼠粪（十四枚，音“加”，指雄鼠。其粪便两头尖的是。）
以上两味药，用水五升煎煮，取汁二升。全部温服，盖被静卧。出汗便痊愈。也能调理劳复证。
琥按：薤味辛温，蓝（板蓝根）味苦寒，也是根据各自的症状而使用的。（又治交接引起的劳复，睾丸肿胀，腹中绞痛，甚至昏厥假死。竹皮汤方。此方也治疗伤寒病愈后，因言语、书写、坐起行走等劳累导致的劳复。）
（一升）
以上一味药，用水三升，煮沸五六次，绞去药渣，一次性服下，立即痊愈。
琥按：上述主治说明提到：交接劳复，是指女劳复，而不是阴阳易。劳复的证候，有阴虚生内热的情况，此方可选而用之。
又治疗阴阳易。
Daqing (4 liang) Gancao (2 liang, honey-fried) Ejiao (2 liang, stir-fried) Xiangchi (2 liang)
The above four herbs. Cut into pieces, decoct with one dou of water, reduce to three sheng. Strain the dregs. Take one sheng warm each time, five or six times a day until the course is completed. Prepare again, always keeping some decoction available. Drink when thirsty. Non-toxic. Clears heat and stops vomiting and diarrhea. Indicated for Shanghan (Cold Damage) from one to two days, up to ten or more days, where the condition is critical, sweating fails to resolve the heat, or after emesis and purgation, the heat persists. It is excellent for stopping severe dysentery. First decoct Daqing and Gancao, obtain four sheng of liquid, strain the dregs. Add Ejiao and Xiangchi. Once Ejiao is completely dissolved, filter out the residue of Xiangchi. Do not let Xiangchi disintegrate. It is advisable to soak Ejiao in advance to facilitate dissolution.
Hu notes: The above formula is an agent for treating irritability and heat in the Lung and Stomach. This arises because exertion consumes Qi, thereby generating irritability and heat. Currently, few practitioners use Daqing. *Bencao Gangmu* states: Its stems and leaves are deep green; its nature is greatly cold, and its taste is bitter and sweet. It is a non-toxic herb among medicinal plants. Physicians must be aware of this.
Also treats post-Shanghan recovery.
Kuizi (2 sheng) Liangmi (1 sheng)
The above two ingredients. Cook together into a thin porridge. Drink it. More is better. Sweating will lead to immediate recovery.
Hu notes: The above formula lubricates the intestines and harmonizes the Middle Jiao Qi. It uses the sweet and cold nature of Kuizi to benefit the orifices, and the sweet and cool nature of Liangmi to nourish the Stomach.
Formula for Nanzi Yiyi (Male Yin-Yi Exchange) after Shanghan disease.
Xie (one large handful. *Zhou Hou Fang* uses Lan, i.e., Banlangen/Isatis Root. Leaves can make indigo dye. Now planted everywhere.) Shufen (14 grains. Pronounced "jia". Male rat feces. Those with pointed ends are selected.)
The above two ingredients. Decoct with five sheng of water, reduce to two sheng. Drink all while warm, lie down covered. Recovery occurs upon sweating. Also regulates Laofu (post-illness relapse due to overexertion).
Hu notes: Xie is acrid and warm; Lan is bitter and cold. Each is used according to its specific indication. (Also treats Laofu caused by sexual intercourse, characterized by testicular swelling, colicky abdominal pain, and syncope-like death. Zhupi Tang formula. This formula also treats Laofu after Shanghan recovery caused by fatigue from speaking, writing, sitting up, or walking.)
(1 sheng)
The above single ingredient. Decoct with three sheng of water, boil five or six times. Strain the dregs. Take in one dose. Immediate recovery.
Hu notes: The aforementioned indications state: Laofu from sexual intercourse refers to Nv Laofu (female-induced relapse), not Yinyi Yi. Among Laofu syndromes, there are cases of internal heat generated by Yin deficiency; this formula can be selected for use.
Also treats Yinyi Yi.
