【鱼】滋养中和，调理胃气
纸鱼（专门作用于脾胃）。就是书中所说的“残鱼”。气味甘甜、平和。不用于药物治疗。据书籍记载，它只出产于苏州、松江和浙江地区。大的不过三四寸长。身体圆滑无鳞。洁白如银。小的更加优良。新鲜食用味道最美。晒干后也很好。做成羹汤食用，能够宽中健胃，而没有油腻损伤脾胃的弊端。
【鱼】服用此鱼有毒，令人头痛腹泻
石斑鱼（专门作用于□）属于有毒之物。凡是服用的人，无不出现头痛并伴随腹泻的症状。大概是因为这种鱼生长在南方溪流山涧的水石之间。长度数寸。有白色鳞片和黑色斑点。浮游在水面上。听到人声就迅速潜入深处。这种鱼只有雌性没有雄性。在二三月间与蜥蜴在水上交配。其胎毒伤害人体。南方有一种土蜂。当地人杀死这种鱼挂在树上，引诱鸟类食用，从而让土蜂全部退去。所以服用它会导致上述疾病发作。但是肉类稍微好一点，而鱼子和鱼肠毒性尤其严重。现在捕鱼的人，经常混杂这种鱼卖给他人食用。必须谨慎对待。
【无鳞鱼】治疗经期风邪，兼补肝肾之气，强健筋骨
鳅鱼（专门作用于经络，兼入肝肾）。禀受土的阳气而生。本性善于钻穴。力量坚实而锐利。没有脚却能穿行。与蛇性质相同。（李时珍说：南方人在黄鳝店里，用缸盛水，养几百条。晚上用灯照，那些身上有花纹的黄鳝，脖子下一定有白点，通身浮在水面上，就要丢弃它们。或者把蒜瓣投入缸中，群鳝就会跳跃不停，这也是物性相互制约的缘故。）所以书籍都记载它能通经达络，能治疗十二经的风邪，以及耳目等孔窍的疾病。比如风邪侵入血脉，导致口眼歪斜，用它的尾血配合少许麝香，右侧患病涂左侧，左侧患病涂右侧，症状停止后立即洗去。（《千金方》说：用鳖血、鸡冠血混合伏龙肝，共同治疗口眼歪斜。）耳痛、鼻出血，痘疹后眼睛生翳，用血滴点即可痊愈。（用血主治，是取其同类相从的道理。）恶疮蛀烂，将鳝鱼打死，用香油涂抹腹部。（涂抹在鳝鱼腹部。）系在疮口上，等到疼痛时取下，观察鳝鱼是否有虫子爬入即去除。（如果没除尽再做一次，之后用人腿骨灰调油外敷。）产后恶露淋漓不尽，肠鸣湿痹，用此鱼煮食即可消除。老人虚痢不止，将此鱼晒干，煅灰存性，调服即可断绝。而且它能通力壮筋，所以大力丸取此鱼同熊筋、虎骨、当归、人参等分进服。（用大鳝鱼重一斤多的取肉，酒蒸后同药物制成丸剂，空腹酒送服两许。）阳道不长，不能延续子嗣，用此鱼血同蛤蚧等药物入药。（方剂见蛤蚧条目内。）都是借助它们的性力来相助。但这种鱼味甘性热，其力量能补益。如果病属虚热，以及流行病后阴虚火旺，食用则必然导致气弱动风和气逆的变化，不可不谨慎。
[Fish] Nourishes harmony and regulates the Stomach Qi.
Zhiyu (Paper Fish) (specifically enters the Spleen and Stomach). This is what books refer to as "Can Yu" (Remnant Fish). Its flavor is sweet, and its nature is neutral. It is not used for therapeutic treatment. According to records, it is produced only in Suzhou, Songjiang, and Zhejiang regions. The large ones are no more than three or four cun long. They have a round body without scales. They are white as silver. The smaller ones are even superior. Fresh consumption tastes best; dried form is also good. Consuming it as soup can broaden the middle and strengthen the Stomach, without the detriment of greasiness damaging the interior.
[Fish] Ingestion causes toxicity leading to headache and diarrhea.
Shiban Yu (Stone-spotted Fish) (specifically enters □) belongs to toxic substances. Those who consume it invariably suffer from headache accompanied by diarrhea. This is likely because this fish inhabits the rocky streams and rivulets of southern regions. It measures several cun in length. It has white scales and black spots. It swims on the water surface. Upon hearing human voices, it dives deeply. This fish exists only in females, with no males. In the second and third lunar months, it mates with lizards on the water surface. Its embryonic toxin harms the human body. There is a type of earth bee in the south. Locals kill this fish and hang them on trees to attract birds to eat them, thereby driving away the earth bees. Thus, consuming it leads to the manifestation of these ailments. However, the meat is relatively less harmful, while the roe and intestines are particularly toxic. Currently, fishermen often mix this fish with others to sell for consumption. One must exercise caution.
[Scaleless Fish] Treats wind-pathogens affecting the menses, supplements Qi of the Liver and Kidney, strengthens sinews and bones.
Qiu Yu (Loach/Eel) (specifically enters the meridians, additionally enters the Liver and Kidney). It is born endowing the Yang Qi of Earth. Its nature is adept at burrowing into holes. Its force is solid and sharp. It moves without feet. It shares the same nature as snakes. (Li Shizhen said: In the south, people keep hundreds of eels in water-filled vats in shops. At night, they illuminate them with lamps. The eels with patterns on their bodies must have white spots under their necks; if they float entirely on the surface, they should be discarded. Alternatively, throwing garlic cloves into the vat causes the eels to jump incessantly, which is also an example of mutual restriction among species.) Therefore, texts record that it can unblock meridians and collaterals, treating wind-pathogens of the twelve meridians, as well as diseases of the ears, eyes, and other orifices. For instance, when wind-pathogen invades the blood vessels causing deviation of the mouth and eye, use its tail blood mixed with a small amount of Moschus (She Xiang), applying to the healthy side (right lesion applied to left, left lesion applied to right); wash off immediately once symptoms cease. (*Qianjin Fang* states: Using Trionycis Carapax et Plastrum (Bie Xue) and Gallus gallus domesticus comb blood (Ji Guan Xue) mixed with Long Gu Tu (Fu Long Gan) treats facial paralysis). For ear pain, epistaxis, and corneal opacity after smallpox/variolous eruption, apply blood drops for cure. (Using blood treats the condition, following the principle of similarity). For foul ulcers and rotting sores, kill the eel, smear sesame oil on its belly (apply to the eel's belly), tie it to the sore, remove when painful, and check if worms have entered the eel; discard if found. (Repeat if not fully cleared; afterwards, apply human tibia ash mixed with oil). For postpartum lochia dripping continuously, borborygmus, and damp bi-syndrome, boiling and eating this fish eliminates them. For elderly patients with persistent deficiency-type dysentery, dry this fish, calcine to ash retaining its nature, and take with mixture to stop it. Furthermore, it can enhance strength and fortify sinews. Thus, Dali Wan (Great Strength Pill) takes this fish along with Ursine Sinew (Xiong Jin), Tiger Bone (Hu Gu), Angelicae Sinensis Radix (Dang Gui), and Ginseng Radix (Ren Shen) in equal parts for administration. (Take flesh from a large eel weighing over one jin, steam with wine, mix with herbs to make pills, take two xu with wine on an empty stomach). For impotence and infertility, use this fish blood combined with Gecko (Ge Jie) and other herbs. (Formula see entry for Ge Jie). All utilize their inherent properties and forces for assistance. However, this fish is sweet in flavor and hot in nature; its power is tonifying. If the disease belongs to deficiency-heat, or yin-deficiency with fire-flaring after epidemic illness, ingestion will inevitably lead to changes such as Qi weakness stirring wind and Qi rebellion. Caution is imperative.
