这就是鳢鱼，俗称里鱼。
味甘、性寒，无毒。
发明：鳢鱼潜伏于泥土中却能战胜水邪。因此能治疗水肿，治愈五种痔疮，治疗湿痹，主治脚气病。妊娠期间出现面部浮肿、脚部肿胀者，用赤小豆煮食鳢鱼非常有效。《丹方》治疗腹部胀大的水肿病，使用活鳢鱼，去除腹内污垢，填入一颗完整的蒜头使其填满，外部涂抹湿润的黄泥，用炭火烤熟后食用，屡见疗效。身上有疮疡的人不可食用，否则会导致疤痕变白。
味甘、性平，有小毒。嘴宽的称为鳗鱼，嘴尖的称为鲡鱼。
发明：鳗鱼虽然有毒，但性能补虚损、益阴精，久病体虚劳瘵者适宜食用。大便稀溏泄泻者不宜使用。其功效专在于滋补真阴，杀灭劳瘵虫，与蛇同类，所以主治功能也相近。
味甘、性大温，无毒。
发明：鳝鱼禀受己土之气，能补益中气、滋养血液。妇女产后恶露淋漓不尽、肠鸣、湿痹都适宜食用。将其晒干存性（烧成灰保留药性），可治疗老年人虚证痢疾。体重一斤以上的大鳝鱼，能助长力气，食用后若感到全身疼痛胀满，需尽力捶打身体。大力丸使用熊筋、虎骨、当归、人参等分研为末，将大鳝鱼用酒蒸熟取肉捣烂制成丸药，每日空腹时以酒送服两许（约一两左右），气力会迅速增长。鳝鱼血力量能助阳，壮年男子阴茎发育不长者，可用育龟丸治疗。该方使用石龙子、蛤蚧、生犀角、生附子、草乌头、乳香、没药、血竭、细辛、黑芝麻、五倍子、阳起石等分研为末，用生鳝鱼血和丸，朱砂为衣，每日空腹时以酒送服一百丸。曾有人服用此药得以延续后代，不能将其视为房中术来讨论。其尾部的血液能治疗口眼歪斜，配合少许麝香，右侧歪斜涂左侧，左侧歪斜涂右侧，症状纠正后立即洗去。其骨头烧成灰，用香油调和涂抹，对汤火烫伤非常有效。
本名鳖鱼。
味甘、性温，有小毒。
发明：鳖鱼无鳞而有甲，所以俗名叫作着甲。江淮地区、黄河、辽河深水处都有生长。身长二三丈，逆流而上龙门能化为龙，味道极其肥美。但容易发动风气，与荞麦同食会让人失音。其肝脏的味道胜过河豚，食用后会导致皮肤干枯脱落，这也是其动风的验证。
This is the snakehead fish (Liyu), commonly known as Liyu.
Sweet, cold in nature, non-toxic.
Invention: The snakehead fish lurks in the soil yet can overcome water pathologies. Therefore, it treats edema (fluid retention swelling), cures five types of hemorrhoids, treats damp-bi syndrome (painful obstruction due to dampness), and primarily addresses Hong Kong foot (a term for beriberi or gout-like conditions). For pregnant women presenting with facial puffiness and foot swelling, boiling and eating this fish with Adzuki beans (Vigna angularis) is highly effective. *Dan Fang* prescribes live snakehead fish for treating abdominal distension due to edema: remove the internal viscera, fill the cavity with a single clove of garlic, coat externally with wet yellow mud, roast over charcoal fire, and eat; this has proven effective repeatedly. Those with sores should not consume it, as it may cause scars to turn white.
Sweet, neutral in nature, slightly toxic. The broad-mouthed variety is called Mianyu (Eel); the pointed-mouthed variety is called Liyu.
Invention: Although Mianyu possesses toxicity, its properties can tonify deficiency and nourish Yin essence, making it suitable for those suffering from chronic illness and consumptive diseases (laozai). It should be avoided by those with loose stools or diarrhea. Its efficacy lies specifically in nourishing True Yin and killing parasites associated with consumptive diseases. Being similar to snakes, its therapeutic indications are also comparable.
Sweet, very warm in nature, non-toxic.
Invention: Eel (Shanyu) inherits the Qi of Ji Earth, capable of tonifying the Middle Jiao and benefiting blood. It is suitable for consumption by women after childbirth experiencing lingering lochia, borborygmus (intestinal rumbling), and damp-bi syndrome. When dried and processed to retain its medicinal nature (charred but retaining essence), it treats deficiency-type dysentery in the elderly. Large eels weighing over one jin can enhance physical strength. After consumption, if one experiences generalized body pain and distension, vigorous massage or beating of the body is required. "Dali Wan" (Great Strength Pill) uses Bear tendon, Tiger bone, Angelica sinensis (Danggui), and Ginseng (Renshen) ground into powder in equal parts; large eels are steamed with wine, the meat extracted, pounded into a paste, and formed into pills. Taken daily on an empty stomach with wine (approx. 1 liang), physical strength increases rapidly. Eel blood powerfully assists Yang energy. For young men with underdeveloped genitalia, "Yugui Wan" (Turtle Nurturing Pill) is used. This formula consists of Shilongzi (Dragon Lizard), Gejie (Gecko), Raw Rhinoceros horn (Xijiao - note: use modern substitutes due to conservation laws), Raw Aconite (Fuzi), Caowutou (Aconitum kusnezoffii), Frankincense (Ruxiang), Myrrh (Moyao), Dragon's Blood (Xuexie), Asarum (Xixin), Black Sesame (Heizhima), Chinese Gallnut (Wubeizi), and Calcined Pyrite (Yangqishi) ground into powder in equal parts. Pills are formed using fresh eel blood and coated with Cinnabar (Zhusha). Taken daily on an empty stomach with wine (100 pills). There are records of individuals using this prescription to produce offspring; it should not be dismissed merely as sexual technique. The blood from the tail treats facial paralysis (deviation of mouth and eyes): apply mixed with a small amount of Musk (Shexiang) to the unaffected side (right deviation applied to left, left to right); wash off immediately once corrected. Bones charred to ash and mixed with sesame oil are highly effective for scalds and burns.
Originally named Bieyu (Soft-shelled turtle).
Sweet, warm in nature, slightly toxic.
Invention: The soft-shelled turtle lacks scales but has a shell, hence the common name "Zhuojia" (wearing armor). It is found in deep waters of the Jianghuai region, the Yellow River, and the Liao River. Reaching lengths of two to three zhang, it can swim upstream through the Dragon Gate and transform into a dragon; its taste is extremely rich and delicious. However, it tends to stir up wind pathogens. Consuming it with Buckwheat causes loss of voice. Its liver tastes superior to that of the pufferfish; consuming it leads to dry, peeling skin, which serves as evidence of its wind-stirring properties.
