厥雄赤紫，厥雌青黑，色晔 如蜃甲光，目亦如之，山中人谓有目而无视也。春夏布丝草
，人物触丝，激射迅于矢，忽不见已攫肉去矣，杀人至死；霜降丝脆，开商树杪，施吐白涎
，乌鹊下啄，则吞之。惟鹿以为膳，猎获之，前左足扼其腰中，首尾盘绕，右足又趾寸解，

治风痹蝮伤，人被其啮者，还食其肉则生。

《蛇谱》记载：这种蛇产自三佛齐国，身体呈环状，直径从几围到几十围不等。它追逐野兽时奔跑迅速，就像在千仞高的山上车轮滚动一样。野兽落入其缠绕中，服用它的油脂后，刀剑便无法伤害人体。
《珍异药品》记载：形状像弯曲的弓，长度大约五、六寸，盘绕成圈。治疗疖毒和痈疽效果良好。
《湖州府志》记载：武康山盛产蝮蛇，名叫“碧飞”，大的像瓮一样粗，小的也像杯案大小。头部呈斧形，眼睛突出，鳞片呈方形纹理且颜色舒缓。雄蛇呈赤紫色，雌蛇呈青黑色，光泽如蜃甲般耀眼，眼睛也是如此。山里人认为它有眼睛却看不见。春夏季节，它散布丝草（指蛇蜕或毒液形成的丝网），人或动物触碰到丝线，会被迅速喷射出的毒液击中，瞬间消失并已被抓走吃肉；致人死亡。霜降时节丝线变脆，它在树梢张开嘴吐出白涎，乌鹊下来啄食，就被它吞食。只有鹿把它当作食物，猎人捕获它后，用前左足扼住它的腰部，头尾盘绕，右足又趾寸解，吃得不剩一点。人得到它后晾干制成干肉，可以入药。凡是西北各地的山，从余英岭以内，都是这种蛇。治疗风痹和蝮蛇咬伤，人被咬后，如果吃掉它的肉就能活命。
赵学敏按语：地方志所说的“碧飞”，我在杭州的山乡里有很多，当地人叫它“方胜板”，因为它全身的花纹像锦缎中的方胜形状，扁平像板，所以得名。咬人最毒，只有野猪能吃它。当地人说冬天蛇冬眠在地里，野猪闻到气味，就会翻石头挖土出来吃掉它。蛇性大热，野猪吃三条，就能度过严冬。《本草纲目》将蝮虺分为两种，蝮就是方胜板，虺就是土锦，俗称灰地匾。恶风顽痹，不用这种猛烈积热的药性来驱除，那么肢体废弛的人就不能再举起，这大概是“以毒攻毒”的意思，猜想碧飞可能是同类但名字不同，记录在此以等待考证。
《尔雅》记载：蟒，即王蛇（注：蛇中最大者，所以叫王蛇），现在深山到处都有，大小不一，颜色像菜花蛇，也有黑色的，当地人叫它乌蟒。捕蛇人有呼唤蛇的方法，不管什么种类的蛇，一呼唤蛇都会围伏不动，听凭选择抓取，唯独不敢伤害蟒蛇，因为蟒蛇受伤则其他蛇就没有了王，会环绕起来唆使人攻击。听说那个人说，蟒蛇天生就有这种种类，生来头上都有“王”字，所以不论大小，蟒蛇一到，各种毒蛇都不敢伤人。
治疗漏疮集验方：取蟒油在铜锅内熬熟，随即把黄蜡放入油内搅匀，涂在油纸上摊成膏药贴在患处，十几天伤口就会封口。
赵学敏按语：蟒蛇名叫王字蛇，它的头上天生有一个“王”字。我在庚子年在奉化长桥，看见一个乞丐手里拿着这条蛇乞讨钱财，这条蛇也不太大，性情很温顺，于是用一千钱买下放生了。《本草纲目》遗漏了这种蛇，因此急忙补录。
The *Snake Spectrum* records: This snake originates from the Kingdom of Samboja (Sanfoqi), with a body shaped like a ring, ranging in girth from several *wei* to dozens of *wei*. When chasing prey, it runs swiftly, resembling a wheel rolling down a cliff thousands of ren high. If an animal falls into its coils and consumes its fat, blades and swords cannot injure the human body.
*Rare Medicinal Substances* records: The shape is like a curved bow, approximately five or six cun in length, coiled into a circle. It is effective in treating furuncles, toxic sores, carbuncles, and ulcers.
The *Huzhou Prefecture Gazetteer* records: Wukang Mountain abounds with pit vipers, named "Bi Fei." The large ones are as thick as urns, while the small ones are as wide as cups or tables. Their heads are axe-shaped with protruding eyes; scales have square patterns and a relaxed coloration. Males are crimson-purple, females are cyan-black, shining with luster like nautilus shell armor, including their eyes. Locals believe they have eyes but cannot see. In spring and summer, they spread silk-like grass (referring to shed skin or venomous webbing); if humans or animals touch the threads, they are struck by rapidly projected venom, disappearing instantly having been seized and eaten; this can be fatal. At the time of Frost Descent, the silk becomes brittle; at the tips of trees, they open their mouths to spit white saliva. Magpies and sparrows come down to peck at it, only to be swallowed. Only deer consume it as food. Hunters capture them, pinning the waist with the front left foot, while the head and tail coil around; the right foot's toes split apart, consuming every bit without remainder. Humans dry them to make jerky for medicinal use. In all mountains northwest of the Yu Ying Ridge, such snakes exist. They treat wind-bi syndrome and viper bites; if bitten, eating the viper's meat ensures survival.
Zhao Xuemin notes: The "Bi Fei" mentioned in the local gazetteer is common in the mountain villages of Hangzhou. Locals call it "Fang Sheng Ban" (Square Knot Board) because its whole-body pattern resembles the square knot design on brocade, and its flat shape resembles a board. It is extremely venomous when biting; only wild boars can eat it. Locals say that in winter, when snakes hibernate underground, wild boars smell their scent, turn over stones, dig up soil, and eat them. Snake nature is intensely hot; after eating three snakes, a wild boar can endure severe winter. *Bencao Gangmu* (Compendium of Materia Medica) divides fu and hui into two types: fu is Fang Sheng Ban, and hui is Tu Jin, commonly known as Hui Di Ban. For stubborn bi syndrome caused by evil wind, unless driven out by this intense, accumulating heat property, paralyzed limbs cannot be raised again. This likely embodies the principle of "using poison to attack poison." I speculate Bi Fei may be the same species under a different name. I record this here awaiting verification.
*Erya* records: Python, also known as King Snake (Note: the largest among snakes, hence called King Snake). Now found everywhere in deep mountains, varying in size. Colors resemble the vegetable flower snake (*Dinodon rufozonatum*), and there are also black ones, locally called Black Python. Snare catchers have methods to call snakes; regardless of species, upon calling, snakes gather and lie still, allowing selection. However, they dare not harm pythons. If a python is injured, other snakes lose their king and will surround and incite attacks. It is said that pythons naturally possess this type, born with a "King" character on their heads, regardless of size. When a python appears, all venomous snakes dare not harm people.
Collection of Proven Experiences for Treating Fistulas: Take python oil, boil it thoroughly in a copper pot, then add yellow beeswax into the oil and stir evenly. Spread onto oiled paper to form a plaster, apply to the affected area. Within ten-plus days, the wound will seal shut.
Zhao Xuemin notes: The python is named Wang Zi She (King Character Snake) because a "King" character is naturally formed on its head. In the Gengzi year, at Changqiao in Fenghua, I saw a beggar holding this snake to beg for money. The snake was not very large and had a quite docile temperament, so I bought it for one thousand cash and released it. *Bencao Gangmu* omitted this snake, so I urgently supplement this entry.
