猪胆一枚，银铫中微火熬成膏，再入冰脑米许，点入眼中。
郭太尉者，真州人，久患目盲，有白翳膜遮睛，遍服眼药，无能效者。有亲仲监税在常
州守官，闻张鼍龙之名，因荐于太尉。太尉请张视之曰∶予眼缘热药过多，乃生外障，视物
昏黑，更无所睹，医者以肝肾虚损治之愈盲。张曰∶请太尉将药点眼并服之，一月取翳微消。
后果一月翳退，双目如旧。因求点药方。乃只用前件修制，点入眼中，微觉翳轻。后又将猪
胆白膜皮曝干，捻作绳子烧灰，待冷点翳，云盛者亦能治之。此方甚好，勿妄传。昆谓猪胆
汁者，甲木之精也，可以莹润乙窍。冰脑者，辛温之品也，可以旋开目翳。膜灰者，化烂之
品也，可以消去翳膜。
羯羊胆出其中，再填入好蜜拌匀，蒸之候干，入钵细研为膏。
福州人病目，两睑赤湿流泪，或痛或痒，昼不能视物，夜不可近灯，兀兀痴坐。其友赵
谦子春语之曰∶是为烂缘血风眼也，我有一药，正治此疾，名曰二百味花草膏。病者惊曰∶
用药品如是，世上方书所未有，岂易遽办？君直相戏耳！赵曰∶我适间有药，当以与君。携
一钱匕，坚凝成膏，使以匙抄少许入口，一日泪止，二日肿消，三日痛定，豁然而愈。乃往
谒赵致谢，且叩其名物。赵笑以前方授之曰∶以蜜采百花，羊食百草，故隐其名以眩人耳。
昆谓内热则睑赤，肝热则出泣，微热则痒，热盛则痛，或痛或痒，皆火之故也。气热则神浊
昏冒，故令昼不能视物；阳胜者善恶火，故令不可以近灯光，此经所谓天明则日月不明，邪
害空窍也。羯羊胆，苦物也，足以胜热；蜜，润物也，足以济火。然曰入口，不曰入眼，则
固服食之剂耳。用之者，使频频噙之，药力相继为良。
【鼍龙点眼方】
取一枚猪胆，在银锅中用微火熬制成膏状，再加入少许冰脑（即冰片），滴入眼中。
郭太尉是真州人，长期患有眼盲症，有白色翳膜遮挡瞳孔，遍试各种眼药均无效。他的亲戚仲某在常州担任监税官，听闻张鼍龙的名声，便将他推荐给郭太尉。郭太尉请张鼍龙诊治，张鼍龙说：“您的眼睛是因为热性药物使用过多，导致生成了外障（指生于黑睛或白睛表面的翳膜），视物昏暗漆黑，完全看不见。医生们用补益肝肾虚损的方法治疗，反而使失明加重。”张鼍龙说：“请太尉将药点入眼中并内服，一个月后翳膜会微微消退。”后果然一个月后翳膜退去，双眼恢复如初。于是请求获得点眼的药方。张鼍龙只用了前面提到的药材进行炮制，点入眼中，感觉翳膜变轻。后来又将猪胆内的白膜皮晒干，搓成绳子烧成灰，待冷却后点敷在翳膜上，声称即使是重症也能治愈。这个方子很好，不要随意传播。吴昆认为，猪胆汁是甲木（肝）的精气，可以滋润乙窍（目）。冰脑是辛温性质的药物，可以迅速开通目翳。膜灰是化腐消烂性质的药物，可以消除翳膜。
【二百味花草膏】
取羯羊（公羊）的胆，从中取出胆汁，再填入优质蜂蜜拌匀，蒸至干燥，放入钵中细细研磨成膏状。
福州有一人患眼病，两眼眼睑红肿潮湿流泪，有时疼痛有时瘙痒，白天不能视物，晚上不敢靠近灯光，呆呆痴坐。他的朋友赵谦（字子春）对他说：“这是烂弦血风眼（一种以眼睑边缘溃烂、痒痛为主要特征的眼病），我有一种药，正好治疗此疾，名叫‘二百味花草膏’。”病人惊讶地说：“用药品种如此之多，世间医书从未有过，难道能轻易办到吗？您只是在开玩笑吧！”赵谦说：“我刚才说的药，现在就给您。”他带了一钱匕（古代量器，此处指少量）药，坚硬凝结成膏状，让病人用勺子舀少许入口服用。一天后眼泪停止，两天后肿胀消退，三天后疼痛止住，豁然痊愈。于是病人前往拜见赵谦致谢，并询问药名和成分。赵谦笑着把前面的方子给他看，说：“用蜂蜜采集百花之精，羊食用百草之叶，所以我隐去具体名称来迷惑世人。”吴昆认为，内热则眼睑发红，肝热则流泪，轻微的热邪则发痒，热盛则疼痛，无论痛还是痒，都是火邪造成的。气分有热则神志浑浊昏冒，所以白天不能视物；阳气偏胜者厌恶火光，所以不敢靠近灯光，这就是《内经》所说的“天明则日月不明，邪害空窍”。羯羊胆是苦味药物，足以克制热邪；蜂蜜是滋润之物，足以济助降火。既然说是入口服用，而不是点入眼中，这固然是内服的药剂。使用者应频繁含漱吞咽，使药力相继发挥作用，这样效果才好。
[Tuolong Eye-Dropping Formula]
Take one pig gallbladder, simmer it over a gentle fire in a silver pot until it becomes an ointment, then add a small amount of Bingnao (Borneol), and instill into the eyes.
Grand Marshal Guo was from Zhenzhou. He had suffered from blindness for a long time, with a white nebula obstructing his pupils. Having tried various eye medicines without effect, he was recommended to Zhang Tuolong by his relative, Zhong, who served as a tax supervisor in Changzhou. Grand Marshal Guo invited Zhang Tuolong to examine him. Zhang said, "Your eye condition arose from excessive use of hot-natured drugs, resulting in an external nebula. You see dimly and darkly, unable to discern anything. Physicians treated you for liver and kidney deficiency, which worsened your blindness." Zhang instructed, "Please apply this medicine to your eyes and take it orally. Within one month, the nebula will slightly recede." Indeed, after one month, the nebula subsided, and both eyes returned to normal. He then requested the formula for the eye drops. Zhang simply prepared the aforementioned ingredients and applied them to the eyes, noting a slight alleviation of the nebula. Later, he dried the white membrane skin inside the pig gallbladder, twisted it into a rope, burned it to ash, and upon cooling, applied the ash to the nebula, claiming it could treat even severe cases. This formula is excellent; do not disseminate it casually. Kun opines that pig bile juice is the essence of Jia Wood (Liver), capable of moistening and nourishing Yi Orifices (Eyes). Borneol is a pungent-warm substance, capable of rapidly opening ocular nebulae. Membrane ash is a substance that resolves putrefaction, capable of eliminating nebulae.
[Hundred-and-Twenty Herb and Flower Ointment]
Extract the bile from a ram's gallbladder, fill it with fine honey, mix well, steam until dry, grind finely in a mortar, and form an ointment.
A man in Fuzhou suffered from an eye disease: his eyelids were red, wet, and tearing, alternating between pain and itching. He could not see during the day and dared not approach lamps at night, sitting dazedly. His friend, Zhao Qian (courtesy name Zichun), told him, "This is Lanxian Xuefeng Yan (Rotting Margins Blood-Wind Eye). I have a remedy specifically for this ailment, named 'Hundred-and-Twenty Herb and Flower Ointment'." The patient exclaimed in surprise, "Such a vast number of medicinal ingredients are unprecedented in medical texts. Is it truly feasible? Are you jesting?" Zhao replied, "I have the medicine ready; I shall give it to you now." He brought a small quantity (one qianbi) of the medicine, which was hard and congealed like paste. He instructed the patient to take a spoonful orally. By the first day, tearing ceased; by the second, swelling subsided; by the third, pain resolved, and he recovered abruptly. The patient visited Zhao to express gratitude and inquire about the names and ingredients. Zhao smiled and presented the previous formula, saying, "Using honey to gather the essence of hundred flowers, and sheep eating the leaves of hundred herbs, I concealed the specific names to mystify people." Kun opines that internal heat causes red eyelids; Liver heat causes tearing; mild heat causes itching; excess heat causes pain. Both pain and itching are due to Fire pathogenic factors. Heat in the Qi level causes turbid spirit and dizziness, leading to inability to see during the day; Yang excess leads to aversion to fire/light, making one unable to approach light sources. This corresponds to the *Neijing* statement: "When Heaven shines bright, the sun and moon lose their clarity, and evil harms the empty orifices." Ram bile is bitter, sufficient to overcome heat; honey is moistening, sufficient to mitigate fire. Since it is taken orally rather than instilled into the eyes, it is indeed an internal preparation. Users should frequently hold it in the mouth and swallow, allowing the medicinal power to act continuously for optimal efficacy.
