伤寒病愈后，或有目复大病者，以其清阳之气不升，而余邪上走空窍也。其病隐涩赤胀
，生翳羞明，头脑骨痛，宜作群队升发之剂饵之，数服斯愈。《伤寒论》曰∶冬时严寒，万
类深藏，君子固密，不伤于寒，触冒之者，乃名伤寒。其伤于四时之气者，皆能为病。又《
生气通天论》曰∶四时之气，更伤五脏，五脏六腑一病，则浊阴之气不得下，清阳之气不得
上。今伤寒时病虽愈，浊阴清阳之气，犹未来复，浊阴清阳之气未复，故余邪尚炽不休，故
其走上而为目之害也。是以一日而愈者，余邪在太阳；二日而愈者，余邪在阳明；三日而愈
者，余邪在少阳；四日而愈者，余邪在太阴；五日而愈者，余邪在少阴；六日而愈者，余邪
在厥阴。七日而复，是皆清阳不能出上窍，而复受其所害也。当为助清阳上出，则治，人参
补阳汤主之，羌活胜风汤主之，加减地黄丸主之， 鼻碧云散亦宜用也。忌大黄、芒硝
苦寒通利之剂；用之，必不治。
强者，盛而有力也；实者，坚而内充也。故有力者，强而欲抟；内充者，实而自收。是
以阴阳无两强，亦无两实。惟强与实，以偏则病。内抟于身，上见于虚窍也。足少阴肾为水
，肾之精上为神水；手厥阴心包络为相火，火强抟水，水实而自收。其病神水紧小，渐小而
又小，积渐之至，竟如菜子许。又有神水外围，相类虫蚀者。然皆能睹而不昏，但微觉
羞涩耳。是皆阳气强盛而抟阴，阴气坚实而有御，虽受所抟，终止于边鄙皮肤也，
内无所伤动。治法∶当抑阳缓阴则愈。以其强耶，故可抑；以其实耶，惟可缓而弗宜助，助
之则反胜，抑阳。酒连散主之。大抵强者则不易入，故以酒为之导引，欲其气味投合，入则可
展其长，此反治也，还阴救苦汤主之，疗相火药也。亦宜用 鼻碧云散。然病世亦间见
，医者要当识之。
伤寒病痊愈后，有的人眼睛再次发生严重疾病，这是因为清阳之气不能上升，而残余的病邪向上侵入头面空窍所致。病症表现为眼部隐痛、涩滞感、发红肿胀，长出翳膜、畏光，以及头脑和骨骼疼痛，应当服用具有升发作用的复方药剂治疗，服用几剂后即可痊愈。《伤寒论》说：冬季天气严寒，万物深藏，君子注意固护肌表，不致受寒，如果触犯冒犯寒气，才称为伤寒。凡是受到四季气候异常影响的，都能导致疾病。另外，《生气通天论》说：四季的气候交替伤害五脏，五脏六腑中只要有一个脏腑生病，那么浊阴之气就不能下行，清阳之气就不能上行。如今伤寒等时行疾病虽然已经痊愈，但浊阴与清阳之气尚未恢复平衡，由于浊阴和清阳之气未复，所以残余的病邪仍然炽盛不止，因此向上侵犯而导致眼睛受害。所以，一天就痊愈的，残余病邪在太阳经；两天痊愈的，残余病邪在阳明经；三天痊愈的，残余病邪在少阳经；四天痊愈的，残余病邪在太阴经；五天痊愈的，残余病邪在少阴经；六天痊愈的，残余病邪在厥阴经。七天以后恢复，这些都是因为清阳之气不能出于上窍，反而受到病邪侵害的缘故。此时应当采用帮助清阳之气上升的方法治疗，以人参补阳汤为主方，羌活胜风汤为主方，加减地黄丸为主方，鼻用碧云散也适宜使用。忌用大黄、芒硝等苦寒通利的药物；如果使用这些药，必定无法治愈。
所谓“强”，是指气势旺盛且有力；所谓“实”，是指质地坚硬且内部充实。因此，有力的事物，强劲而想要聚结；内部充实的事物，坚实而自然收敛。所以阴阳不会同时都强盛，也不会同时都充实。只有当“强”与“实”出现偏颇时才会致病。这种偏盛之气内聚于身体，向上反映在虚窍（如眼目）之中。足少阴肾属水，肾的精气向上化为神水（眼中清澈的液体）；手厥阴心包络属相火，如果火气过强逼迫肾水，肾水因实而自行收敛。其病症表现为神水紧缩变小，逐渐越来越小，积累到极点，竟然像菜籽那样大小。又有神水外围看起来类似被虫蛀蚀的情况。然而这些情况都能看见东西而不昏花，只是略微感到羞涩不适罢了。这都是因为阳气强盛而逼迫阴气，阴气坚实而有抵御能力，虽然受到逼迫，但仅限于边缘皮肤部位，内部没有受到损伤动摇。治疗方法：应当抑制阳热、舒缓阴气即可痊愈。因为它是“强”盛的，所以可以抑制；因为它是“实”的，只宜舒缓而不宜助长，助长它反而会使其更胜，从而抑制阳热。酒连散为主方。大抵“强”盛的东西不容易进入，所以用酒作为引导，希望药物的气味能够投合，进入体内后可以发挥其特长，这属于反治法，还阴救苦汤为主方，这是治疗相火的药物。也适宜使用鼻用碧云散。然而这类病世间也偶尔见到，医生们一定要认识清楚。
After the recovery from Shanghan disease (Cold Damage), some individuals may suffer severe eye diseases again. This is because the clear Yang Qi (vital energy ascending to the head and senses) fails to ascend, while residual pathogenic factors move upward into the orifices. The symptoms include dull pain, astringency, redness, swelling, formation of corneal opacities (翳), photophobia, headache, and bone pain. It is appropriate to administer decoctions with ascending and dispersing properties; after several doses, the condition will resolve. *Shanghan Lun* (Treatise on Cold Damage) states: "In winter, when the cold is severe, all things are deeply hidden. The gentleman keeps himself secure and does not injure himself with cold. Those who are exposed to it are named as having Shanghan. Injuries caused by the Qi of the four seasons can all lead to disease." Furthermore, *Shengqi Tongtian Lun* (Treatise on the Connection between Heaven and Human Life) states: "The Qi of the four seasons alternately injures the Five Zang organs. If any of the Five Zang or Six Fu organs becomes diseased, then turbid Yin Qi cannot descend, and clear Yang Qi cannot ascend." Although the Shanghan or seasonal disease has now healed, the balance between turbid Yin and clear Yang Qi has not yet been restored. Because this balance is unrestored, residual pathogens remain vigorous and ceaseless, thus moving upward to harm the eyes. Therefore, if one recovers in one day, the residual pathogen is in the Taiyang channel; if in two days, in the Yangming channel; if in three days, in the Shaoyang channel; if in four days, in the Taiyin channel; if in five days, in the Shaoyin channel; if in six days, in the Jueyin channel. Recovery after seven days indicates that clear Yang Qi could not emerge from the upper orifices and was instead harmed by them. Treatment should focus on assisting the clear Yang Qi to ascend. The primary formulas include Renshen Buyang Tang (Ginseng Decoction for Supplementing Yang), Qianghuo Shengfeng Tang (Notopterygium Decoction for Overcoming Wind), Jiadi Dihuang Wan (Rehmannia Pill with Modifications), and Biyun San (Green Cloud Powder for the Nose) is also suitable. One must avoid bitter-cold purgatives such as Dahuang (Rhei Radix et Rhizoma) and Mangxiao (Natrii Sulfas); using them will certainly fail to cure the disease.
"Qiang" (Strong) refers to being vigorous and powerful; "Shi" (Excess/Solid) refers to being firm and internally full. Therefore, what is powerful tends to gather and condense; what is internally full tends to contract due to its solidity. Thus, Yin and Yang do not become strong or solid simultaneously. Disease arises only when there is an imbalance of "Qiang" and "Shi." Internally condensed within the body, it manifests externally in the hollow orifices. The Foot-Shaoyin Kidney belongs to Water; the essence of the Kidney ascends to form Shen Shui (divine water, referring to the clear fluid in the eye). The Hand-Jueyin Pericardium belongs to Ministerial Fire. If Fire is strong and forces Water, Water becomes solid and contracts. The symptom is that the Shen Shui becomes tight and small, gradually shrinking until, at its extreme, it resembles the size of a vegetable seed. There may also be cases where the periphery of the Shen Shui appears similar to insect erosion. However, vision remains clear without blurriness, though there is a slight sensation of astringency or discomfort. These conditions occur because Strong Yang forces Yin, and Solid Yin resists. Although subjected to force, the impact is confined to the peripheral skin, causing no internal injury or disturbance. The treatment method is to suppress Yang and soothe Yin, which leads to recovery. Because it is "Qiang" (strong), it can be suppressed; because it is "Shi" (solid), it should only be soothed, not assisted. Assisting it would cause it to prevail further, thereby suppressing Yang. Jiulian San (Wine-Processed Coptis Powder) is the primary formula. Generally, things that are "strong" are difficult to penetrate; therefore, wine is used as a guide to ensure the medicinal flavors match and enter effectively, allowing them to exert their full effect. This is a contrary treatment method. Huanyin Jiuku Tang (Decoction for Restoring Yin and Saving from Bitterness) is the primary formula, which treats Ministerial Fire. Biyun San (Green Cloud Powder for the Nose) is also suitable. Although such diseases are occasionally seen in the world, physicians must recognize them.
