味咸，寒，有毒。主胸中邪气热结痛， 僻，面肿，败漆烧之致鼠，解结散血，愈漆疮，
养筋益气。爪，主破胞，
堕胎。生伊芳洛池泽诸水中，取无时。
杀莨菪毒、漆毒。蟹类甚多，蝤 、拥剑、彭 皆是，并不入药。惟蟹最多有用，仙方
以化漆为水，服之长生。以
黑犬血灌之，三日烧之，诸鼠毕至。未被霜甚有毒，云食水茛所为，人中之，不即疗多死。
目相向者亦杀人，服冬瓜汁、
紫苏汁及大黄丸皆得瘥。海边又有彭
江，不识而啖之，几死，叹
曰∶读
《尔雅》不熟，为劝学人所误。
味辛，寒，有毒。主面痈肿，皮肤说说，时痛，腹中益气，破寒热积聚，除惊悸，去面
黑
生令浦山谷。十月、十二月取。
恶白蔹、白薇。方家不复用，俗不识也。
〔谨案〕《李氏本草》云∶即伏翼屎也，伏翼条
中
名仙鼠，伏翼条以论也。
雄者有小毒。主益精气，强阴道，交接不倦，亦止精。屎，温，无毒。主肠鸣，热中，
消渴，风痹，瘾疹。
原蚕是重养者，俗呼为魏蚕。道家用其蛾止精，其翁茧入术用。屎，名蚕沙，多入诸方
用，不但熨风而以也。
味甘，有毒。主五痔，疮 ，杀诸虫。
能缘树食藤花，形似鳝，取作 食之。炙以熏诸木竹，辟蛀虫。膏，疗诸 疮；又有蝤，
亦相似而短也。
〔谨案〕此
膏，又疗耳中虫痛者。鲵鱼，有四脚，能缘树。陶云鳗鲡，便是谬证也。
味咸，性寒，有毒。主治胸中邪气、热结疼痛，身体歪斜（僻），面部肿胀，由接触生漆或烧漆引发的鼠类疾病（注：此处原文“致鼠”疑为衍文或特定古称，结合下文解漆疮，指漆毒相关病症），化解凝结、消散瘀血，治愈漆疮，滋养筋脉、补益元气。蟹爪，主治胞衣不下，堕胎。生于伊水、洛水等池泽水域中，随时可捕捉。能杀灭莨菪毒和漆毒。蟹的种类很多，蝤蛑、拥剑蟹、彭越蟹等都是，但都不入药。只有普通螃蟹最有药用价值，仙方用它来将生漆化为水状服用以求长生。用黑狗血灌喂它，三天后焚烧，各种老鼠都会聚集而来。未经历霜冻的螃蟹毒性很大，据说是因为吃了水茛菪的缘故，人如果中了这种毒，不及时治疗大多会死亡。眼睛相对而生的螃蟹也会杀人，服用冬瓜汁、紫苏汁以及大黄丸都能痊愈。海边又有彭越蟹，不认识而误食的人，几乎丧命，感叹道：“读《尔雅》不熟，被劝学之人误导了。”
味辛，性寒，有毒。主治面部痈肿，皮肤瘙痒疼痛，时常感到疼痛，腹中益气，破除寒热积聚，消除惊悸，去除面部黑斑。生长在浦地山谷中。十月、十二月采集。畏白蔹、白薇。医家不再使用，世俗之人也不认识。〔谨案〕《李氏本草》说：就是伏翼（蝙蝠）的粪便，在伏翼条中名为仙鼠，在伏翼条中进行论述。
雄性有小毒。主治补益精气，强健性功能，性交不知疲倦，也能固精止遗。粪便，性温，无毒。主治肠鸣，中焦有热，消渴病，风痹，瘾疹。原蚕是第二次饲养的蚕，俗称为魏蚕。道士用它的蛾来止精，它的雄茧加入术类药物中使用。粪便，名为蚕沙，多用于各种方剂中，不仅用于熨治风邪而已。
味甘，有毒。主治五种痔疮，疮疡，杀灭各种寄生虫。能够爬树吃藤花，形状像鳝鱼，捕获后煮熟食用。烤炙后用来熏蒸各种木竹，防止蛀虫。膏脂，治疗各种疮疡；又有蝤蛑，也相似但较短小。〔谨案〕此膏脂，还能治疗耳中虫痛。鲵鱼，有四只脚，能爬树。陶弘景说鳗鲡就是鲵鱼，这是错误的证明。
Salty, cold in nature, toxic. Primarily treats evil qi in the chest, painful heat accumulation, deviation of the body (pì), facial swelling, and diseases caused by contact with raw lacquer or burning lacquer (referred to as "zhi shu" in the text, related to lacquer poisoning). It resolves stagnation, dissipates blood stasis, heals lacquer sores, nourishes sinews, and benefits qi. The claws primarily treat retained placenta and induce abortion. It lives in pools and marshes such as the Yi River and Luo River, and can be caught at any time. It neutralizes the toxicity of Datura metel (Lángdàng) and lacquer. There are many types of crabs; Scylla serrata (yóu móu), fiddler crabs (yōng jiàn), and other varieties are among them, but none are used in medicine. Only common crabs have significant medicinal value. Immortal prescriptions use it to dissolve raw lacquer into a liquid for consumption to achieve longevity. If irrigated with black dog blood and burned after three days, various mice will gather. Crabs that have not yet experienced frost are highly toxic, said to be due to consuming water Datura (shuǐ làngdàng). Humans who ingest this poison and do not receive immediate treatment often die. Crabs with eyes facing each other are also lethal. Consumption of winter melon juice, Perilla juice, and Rhubarb pills can cure the poisoning. By the sea, there is another type called Péngyuè crab; those who eat it without recognizing it nearly die, sighing: "My unfamiliarity with the *Erya* led me astray by those urging learning."
Pungent, cold in nature, toxic. Primarily treats facial carbuncles and swelling, skin itching and pain, frequent abdominal discomfort, benefits qi in the abdomen, breaks up cold-heat accumulations, eliminates palpitations and fright, and removes facial hyperpigmentation. Grows in valleys of Pu region. Collected in October and December. Adversely interacts with Ampelopsis japonica (Báilián) and Clematis chinensis (Báiwēi). Physicians no longer use it, and laypeople do not recognize it. [Note] *Li's Materia Medica* states: This is the feces of the flying squirrel (Fúyì/bat). In the entry for Fúyì, it is named Xiānshǔ (Immortal Mouse), and discussed within the Fúyì section.
Males have slight toxicity. Primarily tonifies essence and qi, strengthens sexual function, prevents fatigue during intercourse, and stops seminal emission. Feces are warm in nature and non-toxic. Primarily treats borborygmus, heat in the middle jiao, xiaoke (wasting-thirst syndrome), wind-bi syndrome, and urticaria. The original silkworm is reared for a second time, commonly known as Wèicán. Daoists use its moth to stop seminal emission, and its male cocoon is added to formulas containing Atractylodes macrocephala (Zhú). The feces, named Cánshā (Silkworm excrement), are widely used in various prescriptions, not only for moxibustion-like warming therapies against wind.
Sweet, toxic. Primarily treats five types of hemorrhoids, sores, and kills various parasites. It can climb trees to eat vine flowers, resembling an eel. Caught and cooked for food. When roasted, it is used to fumigate wood and bamboo to repel insects. The ointment treats various sores; there is also Scylla serrata (Yóumóu), which is similar but shorter. [Note] This ointment also treats ear pain caused by insects. The giant salamander (Níyú) has four feet and can climb trees. Tao Hongjing claimed that Mánlí (Anguilla marmorata) is Níyú, which is an erroneous identification.
