《病源》天行阴阳易病者，是男子妇人天行病新瘥未平复，而与交接得病者，名为阴阳
易也。其男子病新瘥未平复，而妇人与之交接得病者，名为阳易；其妇人新病瘥未平复，男
子与之交接得病者，名为阴易。若二男二女并不相易，所以呼为易者，阴阳相感动，其毒度
着于人，如换易也。其病状，身体热冲胸，头重不能举，眼中生眵，四肢拘急，小腹绞痛，
手足拳，皆即死。其亦有不即死者，病苦小腹里急，热上冲胸，头重不欲举，百节解离，经
脉缓弱，血气虚，骨髓竭，便嘘嘘吸吸，气力转少，着床不能摇动，起止仰人，或岁月方死
。（出第九卷中）

《诸病源候论》中关于天行阴阳易病的记载：所谓天行阴阳易病，是指男子或女子在天行病（传染性外感热病）刚刚痊愈、身体尚未完全恢复时，因进行房事而染病的情况，这被称为“阴阳易”。如果是男子病初愈未复，与女子交合而致病，称为“阳易”；如果是女子病初愈未复，与男子交合而致病，称为“阴易”。如果是两个男子之间或两个女子之间，则不会相互传染，之所以称之为“易”，是因为阴阳之气相互感应，病毒转移附着于人身上，就像更换替换一样。其病症表现为：热气上冲胸部，头部沉重难以抬起，眼中分泌物增多，四肢拘挛紧急，小腹绞痛，手足蜷曲，这种情况通常会立即致死。也有不立即死亡的，患者痛苦于小腹内部拘急，热气上冲胸部，头部沉重不想抬起，全身关节松散无力，经脉松弛软弱，血气虚弱，骨髓枯竭，呼吸短促微弱，体力逐渐减少，卧床无法动弹，起身行走需要依靠他人，有的甚至过了一年半载才死亡。（出自第九卷）
《深师方》治疗男子感染女子“阴易”之病，如果是由于房事或其他虚劳引起，出现小腹坚硬、绞痛、阴器收缩、病情危重欲死的情况，可用以下方法：灸阴头穴一百壮即可好转，最多可灸三百壮以彻底痊愈，效果极好，且不影响日后生育。（《范汪方》与此相同，没有禁忌）
又有一个治疗阴阳易病的方子。
取两只小猪的睾丸，温热后用酒送服，病即可痊愈。（出自第十四卷）
《诸病源候论》关于妇人营卫先虚的论述：妇女原本营卫之气虚弱，又遭受邪热侵袭，在发汗、催吐、泻下等治疗后，经络受损，阴阳之气衰竭，虽然虚邪暂时散去，但真气依然稀少，五脏仍然虚弱，脾胃运化功能未恢复，缺乏津液来滋养身体，因此导致形体消瘦虚弱并产生各种疾病。（出自第九卷）
崔氏治疗烦躁且口渴不止，伴有恶寒，同时热势亢盛的病症，常用竹叶汤，效果也很好。此方不仅用于治疗天行病，凡是久病体虚羸弱，以及疟疾后胸中有痰热的情况，服用此方皆妙。
甘草（二两，炙） 大枣（十五枚，掰开） 半夏（一两，洗） 芍药（三两） 前胡（一两） 黄芩（一两） 小麦（五合） 人参（二两） 粳米（一升） 知母（二两） 麦门冬（四合，去心） 栝楼（一两） 生姜（适量，原文此处似有缺漏，依常理补全或保留原意）
以上十四味药，切碎，用竹筒盛装的清水一斗五升，煎煮至剩余五升，分三次服用。如果不是天行病，而是久病体虚羸弱，胸中生痰热，也可以服用此方，此时需加黄柏二两，去掉黄芩，减少知母一两，去掉栝楼，使用此加减方效果显著。忌食羊肉、海藻、白菜、饴糖。（出自第一卷，按语：这里的“竹 ”指小竹，即箭竹）
《千金方》用于补虚，大病之后正气不足，各类虚劳病症均可参考此方。
取五岁以上、七岁以下新生黄牛的一升乳汁，加入四升水，煎煮浓缩至一升。像喂婴儿吃奶一样，慢慢少量饮用，不可过量，连续服用十天，效果更佳。（出自第十卷）
According to the *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases), regarding Tianxing Yin-Yang Yi Disease: The so-called Tianxing Yin-Yang Yi disease refers to a condition contracted by men or women after recovering from Tianxing disease (infectious febrile diseases) but before their bodies have fully recovered, due to sexual intercourse. This is called "Yin-Yang Yi" (Exchange of Yin and Yang). If a man contracts the disease through intercourse with a woman while his illness has just healed but he has not yet recovered, it is called "Yang Yi"; if a woman contracts the disease through intercourse with a man while her illness has just healed but she has not yet recovered, it is called "Yin Yi". If two men or two women interact, they do not transmit the disease to each other. It is called "Yi" (Exchange) because the Qi of Yin and Yang mutually influence each other, and the pathogenic toxin transfers and attaches to the person, similar to a replacement or exchange. The symptoms include: heat rushing up to the chest, heaviness in the head making it difficult to lift, excessive eye discharge, spasticity and tightness in the four limbs, severe colic in the lower abdomen, and curling of the hands and feet. In such cases, death may occur immediately. There are also cases where death does not occur immediately; the patient suffers from urgency and tightness inside the lower abdomen, heat rushing up to the chest, heaviness in the head making them unwilling to lift it, a sensation of joints separating, slack and weak meridians, deficiency of blood and Qi, exhaustion of bone marrow, short and shallow breathing, decreasing physical strength, inability to move while lying in bed, requiring others to assist when getting up or walking, and some may die after a year or more. (From Volume 9)
The *Shen Shi Fang* (Deep Master's Formulas) treats men who have contracted the "Yin Yi" disease from women. If caused by sexual activity or other forms of deficiency-labor, presenting with hardness and severe colic in the lower abdomen, retraction of the genitals, and critical condition nearing death, one can apply moxibustion to the glans penis for one hundred burns (zhuang) to see improvement, up to three hundred burns for complete recovery. The effect is excellent, and it does not affect future fertility. (The *Fan Wang Fang* agrees, with no contraindications.)
Another formula for treating Yin-Yang Yi disease:
Take two pig testicles, warm them, and swallow them with wine. The disease will then heal. (From Volume 14)
Regarding the discussion in the *Zhu Bing Yuan Hou Lun* on women with prior deficiency of Ying and Wei: Women whose Ying and Wei Qi were previously deficient, having been struck by pathogenic heat, and after undergoing sweating, vomiting, or purging therapies, suffer damage to the meridians. The Yin and Yang Qi become exhausted. Although the pathogenic factors have dispersed, the True Qi remains scarce, the five Zang organs are still deficient, the function of digestion and transformation (Gu Shen) has not recovered, there is a lack of body fluids to nourish the body, leading to emaciation and the generation of various diseases. (From Volume 9)
Cui Shi treats irritability and unquenchable thirst accompanied by aversion to cold and intense heat using the Zhuye Tang (Bamboo Leaf Decoction), which is commonly effective. This formula is not only used for Tianxing disease but is also an excellent prescription for chronic deficiency and emaciation, as well as for phlegm-heat in the chest following malaria.
Gancao (Licorice Root, 2 liang, honey-fried)
Zao (Jujube, 15 pieces, split)
Banxia (Pinellia Tuber, 1 liang, washed)
Shaoyao (Peony Root, 3 liang)
Qianhu (Peucedanum Root, 1 liang)
Huangqin (Scutellaria Root, 1 liang)
Xiaomai (Wheat, 5 he)
Renshen (Ginseng Root, 2 liang)
Jingmi (Rice Grain, 1 sheng)
Zhimu (Anemarrhena Rhizome, 2 liang)
Mendong (Ophiopogon Tuber, 4 he, heart removed)
Gualou (Trichosanthes Fruit, 1 liang)
Shengjiang (Fresh Ginger, appropriate amount)
Cut the above fourteen ingredients, add water from a bamboo vessel totaling 1 dou 5 sheng, decoct until 5 sheng remain, and divide into three doses. If it is not Tianxing disease but rather chronic deficiency and emaciation with phlegm-heat in the chest, this formula can also be used. In this case, add Huangbo (Phellodendron Bark, 2 liang), remove Huangqin, reduce Zhimu by 1 liang, and remove Gualou. Using this modified formula yields significant effects. Avoid mutton, seaweed, Chinese cabbage, and maltose syrup. (From Volume 1, note: "Zhu " refers to small bamboo, i.e., arrow bamboo.)
The *Qian Jin Fang* (Thousand Gold Formulas) is used for tonifying deficiency. After major illnesses, when vitality is insufficient, and for all types of deficiency-labor, this formula can be referenced.
Take one sheng of milk from a newborn yellow cow aged between five and seven years old. Add four sheng of water, decoct until one sheng remains. Administer slowly in small amounts, like feeding an infant. Do not consume too much at once. Take continuously for ten days for best results. (From Volume 10)
