（宋《图经》）
【集解】颂曰∶鳖之无裙，而头足不缩者，名曰纳。亦作 。
肉
【气味】有毒。
颂曰∶食之令人昏塞。以黄 、吴蓝煎汤服之，立解。
甲
【气味】有小毒。
【主治】传尸劳，及女子经闭（苏颂）。
（《纲目》）
【释名】三足鳖。
【集解】时珍曰∶《尔雅》云∶鳖三足为能。郭璞云∶今吴兴阳羡县君山池中出之。或
以鲧化黄熊，即此者，非也。
肉
【气味】大寒，有毒。
颂曰∶食之杀人。
时珍曰∶按∶姚福《庚己编》云∶太仓民家得三足鳖，命妇烹，食毕入卧，少顷形化为
血水，只存发耳。邻人疑其妇谋害，讼之官。时知县黄廷宣鞫问不决，乃别取三足鳖，令妇
如前烹治，取死囚食之，入狱亦化如前人。遂辨其狱。窃谓能之有毒，不应如此。然理外之
事，亦未可以臆断也。而《山海经》云∶从水多三足鳖，食之无蛊疫。近亦有人误食而无恙
者，何哉？盖有毒害人，亦未必至于骨肉顿化也。
【主治】折伤，止痛化血，生捣涂之。道家辟诸厌秽死气，或画像止之
（《拾遗》）
【集解】藏器曰∶生南海。大如钱，腹赤如血。云在水中着水马脚，皆令仆倒也。
时珍曰∶按∶《淮南子》云∶朱鳖浮波，必有大雨。
【主治】丈夫佩之，刀剑不能伤。妇女佩之，有媚色（藏器）。
（宋代《图经本草》）
【集解】苏颂说：没有裙边（甲壳边缘的软肉），且头脚不能缩回的鳖，名叫“纳”。也写作“能”（音同奴来切）。
【气味】有毒。
苏颂说：食用它会导致人昏沉闭塞。用黄芩、吴蓝煎汤服用，立刻就能解毒。
【甲（鳖甲）】
【气味】有小毒。
【主治】治疗传尸劳（一种慢性消耗性传染病，类似肺结核），以及女子经闭不通（苏颂）。
（李时珍《本草纲目》）
【释名】三足鳖。
【集解】李时珍说：《尔雅》记载：鳖长三只脚叫“能”。郭璞说：现在吴兴郡阳羡县的君山池塘里出产这种鳖。有人说这是鲧死后化为黄熊，就是这种鳖，这种说法是不对的。
【肉】
【气味】大寒，有毒。
苏颂说：食用它会致人死亡。
李时珍说：查考姚福的《庚己编》记载：太仓有一户人家得到一只三足鳖，让一位命妇烹煮，吃完后躺下休息，不久身体化为血水，只留下头发而已。邻居怀疑这位妇人谋害丈夫，告到官府。当时的知县黄廷宣审讯未能决断，于是另外取来一只三足鳖，让那位妇人按照之前的方法烹制，找一名死囚犯食用，死囚犯进入监狱后也像前人一样化为血水。于是判决了这起案件。我私下认为，“能”鳖虽然有毒，但不应该导致骨肉瞬间化尽。然而，情理之外的事，也不能凭主观臆断。而且《山海经》记载：从水这个地方有很多三足鳖，吃了它们不会遭受蛊疫之害。近来也有人误食而没有生病的，这是为什么呢？大概是因为有毒害人，也未必至于让骨肉顿时化成水。
【主治】治疗跌打损伤，止痛并消散瘀血，生捣碎后外敷。道家用来辟除各种厌秽之气和死气，或者画它的像来镇止邪气。
（《本草拾遗》）
【集解】陈藏器说：生长在南海。大小如铜钱，腹部红得像血。据说在水中遇到水马（一种水生昆虫）的脚，都会让人跌倒。
李时珍说：查考《淮南子》记载：朱鳖浮在水面上，必定会有大雨。
【主治】男子佩戴它，刀剑不能伤害；女子佩戴它，会有迷人的色泽（陈藏器）。
(Song Dynasty *Tu Jing Ben Cao*)
[Collected Explanations] Su Song stated: The soft-shelled turtle (*Trionyx sinensis*) that lacks the skirt (the soft marginal membrane of the carapace) and whose head and limbs cannot retract is called "Na". It is also written as "Neng" (pronounced like 'nu lai').
[Flesh]
[Flavor and Toxicity] Toxic.
Su Song stated: Consuming it causes dizziness and mental cloudiness. Drinking a decoction of Huang Qin (Scutellariae Radix, 黄芩) and Wu Lan (Isatidis Folium, 吴蓝) will immediately resolve the toxicity.
[Carapace]
[Flavor and Toxicity] Slightly toxic.
[Indications] Treats Chuan Shi Lao (Transmitted Corpse Consumption, a chronic consumptive disease similar to tuberculosis), and amenorrhea in women (Su Song).
(Li Shizhen's *Ben Cao Gang Mu*)
[Name Explanation] Three-legged turtle.
[Collected Explanations] Li Shizhen stated: *Er Ya* records: A turtle with three legs is called "Neng". Guo Pu said: Currently, these are produced in Junshan Pond, Yangxian County, Wuxing Commandery. Some claim this is the form into which Gun transformed after death into a yellow bear; this is incorrect.
[Flesh]
[Flavor and Toxicity] Greatly cold, toxic.
Su Song stated: Consuming it kills people.
Li Shizhen stated: According to Yao Fu's *Geng Ji Bian*: A family in Taicang obtained a three-legged turtle and had a titled lady cook it. After eating, she lay down, and shortly thereafter, her body turned into blood water, leaving only hair behind. Neighbors suspected the lady of murder and sued her. The local magistrate, Huang Tingxuan, could not reach a verdict through interrogation alone. He then obtained another three-legged turtle, instructed the lady to prepare it as before, and had a condemned prisoner eat it. The prisoner entered prison and transformed just like the previous person. Thus, the case was resolved. I privately believe that although "Neng" is toxic, it should not cause bones and flesh to dissolve instantly. However, matters beyond ordinary reason cannot be dismissed by subjective speculation. Furthermore, *Shan Hai Jing* states: In Congshui, there are many three-legged turtles; consuming them prevents gu poison and epidemics. Recently, some people have mistakenly eaten them without harm. Why is this? Perhaps while toxicity harms people, it does not necessarily lead to instantaneous dissolution of bones and flesh.
[Indications] Treats traumatic injuries, relieves pain, and resolves blood stasis; apply externally as a fresh paste. Daoists use it to ward off various repulsive foul qi and dead qi, or draw its image to suppress evil influences.
(*Ben Cao Shi Yi*)
[Collected Explanations] Chen Zangqi stated: Grows in the South Sea. Size like a coin, belly red as blood. It is said that encountering the feet of the "water horse" (a type of aquatic insect) in the water causes one to fall.
Li Shizhen stated: According to *Huainanzi*: When the Zhu Turtle floats on waves, heavy rain is certain.
[Indications] Men who wear it are protected from sword and knife injuries. Women who wear it acquire a charming allure (Chen Zangqi).
