图经文具鳖甲条下。
陈藏器∶按 鱼合作鼍字，《本经》作鼍。鱼之别名，已出《本经》。今以鼍为 ，非也，

吐气成雾致雨，力至猛，能攻陷江岸，性嗜睡，恒目闭，形如龙，大长者，自啮其尾，极难

周兴嗣常食其肉，后为鼍所喷，便为恶疮，此物灵强，不可食。既是龙类，宜去其鱼。肘
后方∶治五尸。鼍肝一具，熟煮切食尽，亦用蒜齑食之。
味辛，微温，有毒。主要治疗心腹部的症瘕（腹部结块），潜伏坚硬的积聚，寒热往来，女子崩漏（非经期大量出血），下血五色，小腹及阴部相互牵引疼痛，疮疥死肌，五种邪气引起的涕泪和时常惊悸，腰部沉重疼痛，小儿气癃（小便不通）溃烂。
肉：主要治疗少气、呼吸短促，双脚无力站立。生于南海的池泽中。随时可以采集。（蜀漆为其辅药，畏惧狗胆、芫花、甘遂。）
陶隐居说：鼍，就是现在的鼍甲，使用时应当炙烤。皮可以用来蒙鼓，肉非常补益。这种动物很难杀死，用沸水浇入口中，进入腹部后，很久才能剥开。鼋肉也有补益作用，食用方法与鼍相同。这些老年的鼍和鼋多能变化为邪魅，如果不是紧急情况不要食用。现在参考陈藏器《本草》说：主要治疗恶疮，腹内症瘕。甲更好，炙烤后浸酒服用，口中唾液有毒。臣禹锡等谨按《蜀本图经》说：生长在湖畔土窟中，形状像守宫（壁虎）但较大，长一丈多，背尾都有鳞甲，现在江南各州都有。《药性论》说：鼍甲，臣，味甘，平，有小毒。主治百邪鬼魅，治疗妇人带下，去除腹内血积聚伏坚相互牵引结痛。孟诜说：鼍，治疗惊恐及小腹气疼。日华子说：鼍，治疗牙齿疾病、疳积、宣露（牙龈萎缩）。甲用法功效相同，入药需炙烤。又说鼋甲，臣，平，无毒。主治五脏邪气，杀灭百虫毒，消除百药毒，接续人筋骨，又用其脂涂抹铁烧之便明亮。淮南王方：在术中使用它。陈藏器说：鼋甲功用同鳖甲，炙烧后浸酒。主治瘰疬，杀虫风，疮，风顽疥瘙。肉，主治湿气，邪气，各种蛊毒。张鼎说：膏，摩治风及恶疮。
《图经》详细记载在鳖甲条下。
陈藏器：按，鱼应作“鼍”字，《本经》作“鼍”。鱼的别名，已出《本经》。现在以鼍为“鱼”，是不对的，宜改为“鼍”。
鼍能吐气成雾致雨，力量至猛，能攻陷江岸，性格嗜睡，常闭眼，形状像龙，大的长者，自咬其尾，极难死，声音很可怕。人在穴中挖掘它，百人挖掘也须百人牵拉，一人挖掘也须一人牵拉，不然终究不可出来。梁周兴嗣常吃它的肉，后来被鼍喷到，便生恶疮，此物灵性很强，不可食用。既然是龙类，宜去掉其“鱼”旁。《肘后方》：治疗五尸。鼍肝一副，煮熟切食尽，也可用蒜泥佐食。
Pungent, slightly warm, toxic. Primarily treats zhangjia (abdominal masses) in the heart and abdomen, latent and hard accumulations, alternating chills and fever, metrorrhagia (profuse non-menstrual bleeding) in women, discharge of blood in five colors, mutual pulling pain in the lower abdomen and yin region, sores, scabies, and necrotic tissue, frequent startle with tears and nasal discharge caused by five pathogenic factors, heavy and painful sensation in the waist, and infantile qi long (urinary retention) with ulceration.
Meat: Primarily treats shortness of breath, labored breathing, and inability to stand on the feet. Grows in ponds and marshes of the South Sea. Can be collected at any time. (Shuqi [Patrinia Herba] is its assistant herb; it fears gou dan [Dog Gallbladder], Yuanhua [Daphne Genkwa Flower], and Gansui [Kansui Root].)
Tao Hongjing states: Tuosuo (Alligator Sinensis Shell), also known as tuo jia, should be roasted before use. Its skin can be used to drum heads, and its meat is highly nourishing. This creature is difficult to kill; even if boiling water is poured into its mouth and enters the stomach, it takes a long time to peel open. Yuansuo (Softshell Turtle) meat is also nourishing; eat it in the same manner as Tuosuo. These older creatures often transform into evil spirits; do not eat them unless in an emergency. Currently, according to Chen Cangqi's Bencao: It primarily treats malignant sores and abdominal zhangjia. The shell is better; roast it and take it soaked in wine, as the saliva is toxic.臣 Yuxi et al. note according to Shuben Tujing: It grows in earthen burrows by lake shores, resembling a gecko but larger, over one zhang long, with scales and armor on its back and tail; it is found in all prefectures of Jiangnan. Yaoxing Lun states: Tuojia, minister, sweet, neutral, slightly toxic. Primarily treats various evils and ghosts, manages leukorrhea in women, and removes internal blood accumulations causing hard, latent, pulling pain. Meng Shen states: Tuosuo treats fright and qi pain in the lower abdomen. Rihuazi states: Tuosuo treats dental issues, ganji (childhood malnutrition syndrome), and gingival recession. The shell has the same efficacy and should be roasted for medicinal use. He also states: Yuanjia, minister, neutral, non-toxic. Primarily treats pathogenic factors in the five zang organs, kills hundred-insect toxins, eliminates hundred-drug toxins, reconnects human tendons and bones, and its fat applied to iron makes it bright when burned. Huainan Wang Fang: Uses it within Shu preparations. Chen Cangqi states: Yuanjia functions similarly to Biejia (Trionycis Carapax); roast and burn, then soak in wine. Primarily treats luoli (scrofula), kills wind parasites, treats sores, and stubborn scabies caused by wind. Meat primarily treats dampness, pathogenic factors, and various gu poisons. Zhang Ding states: Ointment, massage for wind and malignant sores.
The detailed description is under the entry for Biejia in Tujing.
Chen Cangqi: According to records, "Yu" should be written as "Tuo"; Benjing writes it as "Tuo". The alias "Yu" has already appeared in Benjing. Using "Tuo" as "Yu" now is incorrect; it should be corrected to "Tuo".
Tuosuo can exhale air to form fog and cause rain, possesses immense strength capable of breaching riverbanks, is lethargic with eyes often closed, resembles a dragon, large individuals may bite their own tails, is extremely difficult to kill, and has a terrifying voice. When digging it from its burrow, a hundred people digging require a hundred people pulling, or even one person digging requires one person pulling; otherwise, it cannot be extracted. Liang Zhou Xingsi once ate its meat and was later spat upon by a Tuosuo, resulting in malignant sores; this creature has strong spiritual power and should not be eaten. Since it belongs to the dragon category, the "fish" radical should be removed. Zhoubian Fang: Treats wushi (five corpse poisons). One pair of Tuogan (alligator liver), cooked thoroughly, sliced and consumed entirely; can also be eaten with minced garlic.
