黄连（四两） 黄芩（二两） 芍药（二两） 阿胶（三两） 鸡子黄（二枚） 上五味，以水六升，先煮三物，
煮取二升，去渣，纳胶烊尽，小冷，纳鸡子黄，小冷而纳鸡子黄，则不至凝结而相和。搅令相得，温服七合，日三服。
少阴病，得之二、三日以上，心中烦，不得卧，黄连阿胶汤主之。此少阴传经之热邪，扰动少阴之
气，故以降火养阴为治，而以鸡子黄引药下达。
赤石脂（一斤，一半全用，一半筛末） 干姜（一两） 粳米（一升） 上三味，以水七升，煮米令熟，去渣、纳
赤石脂末，方寸匕，温服七合，日三服、若一服愈，余勿服。兼末服，取其留滞收涩。
少阴病，下利，便脓血者，寒热不调，则大肠为腐，故成脓血，与下利清谷绝不同。桃花汤主之。
《本草》∶赤石脂∶疗下利赤白。
少阴病，二、三日至四、五日，腹痛，小便不利，下利不止，便脓血者，桃花汤主之。
半夏（洗） 桂枝（去皮） 甘草（炙） 上三味，等分，各别捣筛；已合治之，白饮和服方寸匕，日三服。

少阴病，咽中痛，足少阴之脉，循喉咙，挟舌本。半夏散及汤主之。《本草》∶半夏治喉咽肿痛。桂枝
治喉痹，此乃咽喉之主药，后人以二味为禁药，何也？
黄连（四两） 黄芩（二两） 芍药（二两） 阿胶（三两） 鸡子黄（两个） 以上五味药，用六升水，先煎煮前三味药，
煮至剩余二升，滤去药渣，加入阿胶使其完全溶化，待药液稍凉后，再加入鸡子黄，如果药液太热就加入鸡子黄，就会导致鸡蛋凝结而不能与药液混合均匀。搅拌使药液与鸡蛋充分融合，每次温服七合，每日服用三次。
少阴病（少阴经受邪所致的病证），患病两三天以上，心中烦躁，无法入睡，应用黄连阿胶汤主治。这是少阴经传入的热邪，扰动少阴经的气机，所以治疗以降心火、养肾阴为主，并用鸡子黄引导药力下达。
赤石脂（一斤，一半整块使用，一半研成细末） 干姜（一两） 粳米（一升） 以上三味药，用七升水，煮米至熟烂，滤去药渣，加入赤石脂细末，每次服用一方寸匕的量，温服七合，每日服用三次。如果一次服药后病愈，剩下的药就不要服用了。将药末混入药液中一起服用，是为了利用其滞留收敛的作用。
少阴病，出现腹泻，大便带有脓血的情况，是因为寒热不调，导致大肠腐败，从而形成脓血，这与下利清谷（腹泻排出未消化的食物）完全不同。应用桃花汤主治。
《本草》记载：赤石脂，治疗下利赤白（痢疾，大便带脓血）。
少阴病，从两三天到四五天，出现腹痛，小便不利，腹泻不止，大便带有脓血的情况，应用桃花汤主治。
半夏（洗净） 桂枝（去皮） 甘草（炙烤） 以上三味药，等量分配，分别捣碎过筛；然后混合在一起处理，用白饮（米汤）调和，每次服用一方寸匕的药散，每日服用三次。
如果不能服用散剂，则用一升水，煮沸七次，加入两方寸匕的药散，再煮沸三次，离火，待药液稍凉，少量多次地咽下。治疗上焦疾病的药物，应当减小剂量。
少阴病，咽喉疼痛，足少阴肾经的经脉，沿着喉咙，挟持舌根。应用半夏散及汤主治。《本草》记载：半夏治疗喉咽肿痛。桂枝
治疗喉痹（咽喉闭塞不通），这两味是治疗咽喉疾病的主药，为什么后人将它们列为禁药呢？
Huanglian (Coptidis Rhizoma, four liang) Huangqin (Scutellariae Radix, two liang) Shaoyao (Paeoniae Radix Alba, two liang) Ejiao (Colla Corii Asini, three liang) Jizihuang (Ovi Galli Albumen, two pieces) The above five herbs are boiled in six sheng of water. First, boil the first three herbs until two sheng remain. Strain out the dregs, add Ejiao and melt it completely. When the decoction has cooled slightly, add the Ovi Galli Albumen. If added when too hot, the albumen will coagulate and fail to mix well. Stir thoroughly to ensure uniformity. Take seven ge warm, three times a day.
Shaoyin disease (disease pattern involving the Shaoyin channel), presenting after two or more days with mental restlessness and inability to sleep, is primarily treated with Huanglian Ejiao Tang. This condition involves heat pathogen transmitted into the Shaoyin channel, disturbing the Qi of Shaoyin. Therefore, the treatment principle is to descend heart fire and nourish yin, using Ovi Galli Albumen to guide the medicinal action downward.
Chishizhi (Halloysitum Rubrum, one jin; half used whole, half sifted into powder) Ganjiang (Zingiberis Rhizoma, one liang) Jingmi (Oryza Sativa var. glutinosa, one sheng) The above three herbs are boiled in seven sheng of water until the rice is cooked. Strain out the dregs, then add the Halloysitum Rubrum powder. Administer one fangcun bi per dose. Take seven ge warm, three times a day. If symptoms resolve after one dose, discontinue the remaining medication. Mixing the powder into the decoction utilizes its astringent and retaining properties.
In Shaoyin disease, if diarrhea occurs accompanied by pus and blood in the stool, it results from disharmony of cold and heat causing putrefaction in the large intestine, forming pus and blood. This is distinctly different from diarrhea with undigested food. It is primarily treated with Taohua Tang.
Bencao states: Halloysitum Rubrum treats dysentery with red and white discharge.
In Shaoyin disease, progressing from two to five days, if abdominal pain, difficulty in urination, persistent diarrhea, and pus and blood in the stool occur, it is primarily treated with Taohua Tang.
Banxia (Pinelliae Rhizoma, washed) Guizhi (Cinnamomi Ramulus, peeled) Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried) The above three herbs are taken in equal parts, each separately pounded and sifted, then mixed together. Mix with Baiyin (rice water) and administer one fangcun bi of the powder per dose, three times a day.
If the powder cannot be taken dry, boil one sheng of water for seven boils, add two fangcun bi of the powder, boil for another three boils, remove from heat, let cool slightly, and swallow slowly in small amounts. Medications treating the upper jiao should have reduced dosages.
For Shaoyin disease manifesting as throat pain, since the Foot-Shaoyin Kidney channel traverses the throat and surrounds the root of the tongue, Banxia San Ji Tang is primarily indicated. Bencao states: Pinelliae Rhizoma treats soreness and swelling of the throat and pharynx. Cinnamomi Ramulus treats throat obstruction (houbi). These two are primary herbs for throat diseases; why did later practitioners prohibit their use?
