《病源论》云∶青 蛇者，正绿色，喜绿树及竹上，自挂树竹色一种，人看不觉，若人
林中行，有落人颈背上者，然自不甚啮人，啮人必死。此蛇无正形，大者不过四、五尺，世
人皆呼为青条蛇，言其与枝条同色，乍看难觉，其尾二、三寸，色黑者，名 。毒最猛烈，
中人立死。
《葛氏方》云∶青 中人，立死。竹中青 蛇螫人方∶
灸疮中三壮，毒即不行也。猝无艾，刮竹皮及纸，皆可以丸，又了无此者，便以火烬就
热烧疮。
又方∶破乌鸡冠血，及热以拓疮上。
《范汪方》治青 蛇螫人方∶

《诸病源候论》说：青蝮蛇，体色正绿，喜欢栖息在绿树和竹子上，其颜色与树木竹子相同，人眼难以察觉。如果人在林中行走，有蛇落在人的颈背上的话，这种蛇虽然平时不太咬人，但一旦咬人，被咬者必死无疑。这种蛇没有固定的形状，大的不过四、五尺长，世人都叫它青条蛇，意思是它的颜色与枝条相同，乍看很难发现，它的尾巴二、三寸长，尾部颜色发黑的，名叫[缺字]（注：原文此处似有脱漏或异体字，通常指青蝮蛇的一种特征），毒性最为猛烈，中人立即死亡。
《葛氏方》说：青蝮蛇咬中人，立即死亡。治疗竹林中青蝮蛇咬伤的方法：在伤口处灸三壮，毒气就不会扩散了。如果没有艾草，刮取竹皮及纸张，都可以做成丸药敷用；如果连这些都没有，就用火灰趁热敷烧伤口。
《范汪方》治疗青蝮蛇咬伤的方法：将雄黄和干姜研成末，敷在伤口上，效果很好。
《葛氏方》治疗蛇缠绕人不肯松口的方法：用热水淋浇，蛇就会松开。如果没有热水，让人对着尿尿也可以让蛇松开。（现在按语：《千金方》、《集验方》也是这么说的。）
《葛氏方》治疗蛇钻进人口中出不来的方法：用艾灸蛇的尾巴，蛇就会出来。如果没有火，用刀环绕割断蛇尾的皮肤，只要皮断开，就可以把蛇引出来，蛇皮会倒着脱落从而取出。
《千金方》治疗蛇钻进人口中出不来的方法：用刀剖开蛇尾，塞入生花椒三、四颗，一会儿蛇就出来了。
《葛氏方》治疗蛇咬人，牙齿折断留在肉中出不来，疼痛难忍的方法：取蛤蟆的肝脏，敷在伤口上，牙齿立刻就会出来。（《短剧方》也是这么说的。）
又说：治疗蛇骨刺伤人，毒痛肿胀发热，与蛇咬伤无异的方法：取如大豆大小的铁精，用管子吹入伤口中。
又一方：烧死老鼠捣成末，敷在伤口中。
The *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Symptoms of All Diseases) states: The Qingfu snake (Green Viper, *Qing She*), which is bright green in color, prefers to inhabit green trees and bamboo. Its color blends with that of the trees and bamboo, making it difficult for humans to perceive. If a person walks in a forest and a snake falls upon their neck or back, although this snake rarely bites people normally, if it does bite, the victim will certainly die. This snake has no fixed shape; the largest individuals are no more than four or five chi long. People generally call it the "Qing Tiao Snake" (Green Strip Snake), implying its color is identical to branches, making it hard to notice at first glance. Its tail is two or three cun long, and those with black tails are named [missing character]. Its venom is extremely potent; a bite causes immediate death.
The *Ge Shi Fang* (Prescriptions by Ge Hong) states: A bite from the Qingfu snake causes immediate death. Prescription for treating bites from Qingfu snakes in bamboo forests: Moxibustion of three moxa cones directly on the wound will prevent the poison from spreading. If mugwort is unavailable, scraping bamboo bark and paper can be formed into pills for application. If neither is available, apply hot ash to the burned wound.
Another prescription: Break open the comb of a black chicken to obtain blood, and apply it while hot to the wound.
The *Fan Wang Fang* (Prescriptions by Fan Wang) for treating Qingfu snake bites: Apply a powder of Realgar (Xionghuang, 雄黄) and dried ginger (Ganjiang, 干姜) to the wound; this is effective.
The *Ge Shi Fang* for treating a snake coiling around a person and refusing to let go: Pour hot water over it, and it will release. If hot water is unavailable, urinating on it will also cause it to release. (Current commentary: The *Qianjin Fang* and *Jiyan Fang* agree with this.)
The *Ge Shi Fang* for treating a snake that has entered a person's mouth and cannot get out: Apply moxibustion to the snake's tail, and it will exit. If fire is unavailable, use a knife to cut around the snake's tail skin until it breaks, then pull gently; the skin will slip off backwards, allowing the snake to be removed.
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) for treating a snake that has entered a person's mouth and cannot get out: Cut open the snake's tail with a knife, insert three or four raw Sichuan peppercorns (Shengjiao, 生椒), and the snake will come out shortly.
The *Ge Shi Fang* for treating a snake bite where the fang is broken off and embedded in the flesh, causing unbearable pain: Take the liver of a toad (Xiamu, 虾蟆) and apply it to the wound; the fang will emerge immediately. (The *Duanju Fang* agrees with this.)
Furthermore, regarding treatment for injuries caused by snake bones piercing the skin, resulting in toxic pain, swelling, and heat, which are no different from snake bites: Take Iron Efflorescence (Tiejing, 铁精) the size of a soybean and blow it into the wound using a tube.
Another prescription: Burn a dead mouse, grind it into powder, and apply it to the wound.
The *Seng Shen Fang* (Prescriptions by Monk Shen) for treating a snake fang broken off and embedded in the flesh: Apply fresh blood from a live mouse to the wound, wrap it with cotton, and the fang will emerge after two days.
Another prescription: For injuries caused by snake bones piercing the skin, take Realgar (Xionghuang, 雄黄) the size of a soybean and insert it into the wound.
