螃蟹完全禀受了天地间至阴之气，所以味道咸、性平、无毒，这明显是象应水的表现。但是它的甲壳颜色青而对应木行，所以主要入肝经和肾经。它是软化坚积、清除虚热、补益虚弱、消除瘕块积聚、治疗痞疾息肉、阴部蚀疮痔疮、疟母劳热、血瘕骨蒸劳复以及产后蓐劳的重要药物。
鳖甲，用于治疗劳损消瘦、骨蒸潮热、温疟（一种以寒热往来为特征的疟疾）、往来寒热、癖瘕（腹内结块）、息肉、阴部蚀疮痔疽等症。它能退除潜伏在骨骼中的伏热，滋养肝肾的阴气，治疗小儿胁下坚硬、妇人产后虚劳，去除痞块、化解积滞，治疗血瘕腰痛，治愈肠痈，消肿并下行瘀血，且有堕胎作用。蟹肉味甘而性冷，主治中焦损伤、益气、凉血清热、补益阴虚。但不宜过量食用，因为其性寒冷，孕妇食用会导致胎儿颈部短小。
按语：龟甲以自然腐烂者为佳，鳖甲以未经过热水烫煮者方为上乘，如果肝肾没有热邪的人应当忌用。
螃蟹禀受水气而生，味道咸，气味果决，《黄帝内经》说它有毒，然而现在人们多吃它大多没有害处。那些真正有毒的，大抵是形态质地怪异的，就像后文所记载的那样。螃蟹外有硬壳内有肉，这是阴包裹阳的表现。它入足阳明胃经和足厥阴肝经。《黄帝内经》说：“热邪蕴结于内，用咸寒之品治疗。”所以螃蟹主治胸中邪气热结疼痛。面瘫口眼歪斜，是由于厥阴经风热所致；面部肿胀，是由于阳明经热邪壅盛所致。解除这两条经络的热邪，则筋脉得到滋养，气机自然受益，口眼歪斜和面部肿胀自然消退。咸味入血分并能软化坚积，所以能解散结节、消散瘀血。漆树汁遇到螃蟹就会化为水，焚烧螃蟹可以招集老鼠到庭院中，这种物性的相互感应与制约，其深奥的道理无法穷尽。治愈漆疮，是因为螃蟹能解漆毒。蟹爪性质迅利，所以能破胞堕胎。治疗产后腹痛、恶露不下者，用酒送服蟹肉；治疗筋骨骨折损伤者，将生蟹捣碎炒熟，用于治疗断绝的骨骼。去掉蟹壳，同黄柏捣烂微炒，纳入疮口中，筋脉就能连接。治疗小儿囟门不合（解颅），用蟹螯同白及粉末，捣碎涂抹，直到囟门闭合为止。骨节离脱，用生蟹捣烂，倒入热酒。连续饮用数碗，剩下的药渣涂在患处，半天内骨肉间发出响声即痊愈。中了黄鳝鱼毒，吃螃蟹即可解毒。治疗孕妇跌倒僵仆，胎气上抢心胸。有蟹爪汤神奇地治疗死胎在腹中，或双胎中一死一生，服用此药令死者排出，生者平安，神效验灵。用蟹爪一升，甘草二尺，东流水一斗，用芦苇柴火煮至二升，滤去药渣，加入真阿胶三两，使其溶化，一次性服下，或分两次服用。如果病人困倦不能服药，灌入也能救活。蟹性寒冷，能散血热致病，所以跌扑损伤、血热瘀滞者适宜食用；如果是因寒凝结的血瘀，脾胃虚寒滑泄，腹痛喜热，怕冷的人，都不适宜食用。有独螫（一只钳子）、独目（一只眼睛）、两目相对、六足四足、腹下有毛、腹中有骨头、背有星点、足上有斑纹、眼睛赤红的螃蟹，都有毒，不可食用。被其毒所伤，可用冬瓜汁、紫苏、蒜豉、芦根汁来解毒。不可与柿子及荆芥同食，否则能引发霍乱、动风，木香汁可以解毒。
螃蟹，能散血解结、益气养筋、清除胸中热闷烦扰、去除面部肿胀和口眼歪斜、治愈漆疮、化痰、续接筋骨使筋脉连接。风疾患者食用，疾病会复发。孕妇食用，会导致胎儿横位难产。蟹壳能合拢小儿的囟门，蟹爪能使孕妇堕胎。生蟹捣碎敷于赤白游肿（丹毒类皮肤病）处。作为食物不宜多吃，能诱发疮疡、动气。小儿误食蟹、鸡、犬肉，尤其不要给它们吃。海马种类也属于此类，雌雄不分离，头部像马，身体……（原文此处可能有缺漏或异体字，依语境推测为描述形态）。布网于水面。主下胎易产，是难产的圣药。兴阳不痿，辅助房中术春方。水母又名海重，东海多生长，形状像白沫，游泳时依靠虾作为眼睛，主治妇人生产劳损血凝、小儿风疾火丹毒。
Crabs completely inherit the supreme Yin Qi of heaven and earth, thus their taste is salty, nature is neutral, and they are non-toxic, which is as clear as water. However, the shell color is green corresponding to Wood, so it specifically enters the Liver meridian and benefits the Kidney. It is a key herb for softening hardness, clearing heat, tonifying deficiency, removing masses, treating warm malaria with alternating chills and fever, fixed masses (Zhen Jia),痞疾 polyps, genital erosion and hemorrhoids, malaria mother (Nan Mu) with consumptive fever, blood masses (Xue Jia) with bone-steaming consumption relapse, and postpartum confinement consumption.
Bie Jia (Turtle Shell), used for consumptive emaciation with bone-steaming fever, warm malaria, alternating chills and fever, fixed masses (Pi Jia), polyps, genital erosion and hemorrhoid abscesses, withdraws latent heat from the bones, nourishes Yin in the Liver and Kidney, treats hardness under the hypochondrium in children, postpartum consumption in women, removes痞 masses and resolves accumulations, treats blood masses and lower back pain, cures appendicitis (Chang Yong), reduces swelling and expels stasis, and induces abortion. Crab meat has a sweet taste and cold nature, primarily treating middle jiao injury, benefiting Qi, cooling blood heat, and tonifying Yin deficiency. It should not be consumed excessively due to its cold nature; pregnant women eating it may result in infants with short necks.
Note: Gui Jia (Tortoise Shell) is best when naturally decayed; Bie Jia is superior when not boiled in hot water. It is contraindicated if there is no heat in the Liver and Kidney.
Crabs are born from Water Qi, have a salty taste and decisive aroma. The Classic states they are toxic, yet nowadays people consume them frequently without harm. Those that are toxic generally have strange forms or textures, as recorded later. They have an external shell and internal flesh, representing Yin enveloping Yang. They enter the Foot-Yangming Stomach meridian and Foot-Jueyin Liver meridian. The Classic says: "When heat dominates internally, treat with salty-cold substances." Therefore, they mainly treat evil qi and heat knots causing pain in the chest. Facial deviation (Kou Yan Pi Xie) is due to Jueyin wind-heat; facial swelling is due to Yangming heat obstruction. Resolving the heat in these two meridians allows the sinews to be nourished and Qi to benefit, curing facial deviation and swelling. Salty flavors enter Blood and soften hardness, thus resolving knots and dissipating blood stasis. Lacquer juice turns into water upon contact with crab; burning crabs can attract mice to the courtyard. This mutual induction and restraint of material natures cannot be fully explored. Treating lacquer dermatitis works because it resolves lacquer toxicity. Crab claws have a swift and sharp nature, thus breaking membranes and inducing abortion. For postpartum abdominal pain with stagnant lochia, consume crab meat with wine. For bone and joint fractures, crush fresh crabs and stir-fry them to treat severed bones. Remove the shell, mash with Huang Bo (Phellodendron Bark), lightly stir-fry, and apply to the wound to reconnect sinews. For pediatric fontanelle non-closure (Jie Lu), mix crab claws with Bai Ji (Bletilla Rhizome) powder, mash, and apply until healed. For dislocated joints, crush fresh crabs, pour hot wine over them, drink several bowls continuously, and apply the residue to the affected area; if bones and flesh make sounds within half a day, it heals. To antidote eel poisoning, eat crab. To treat pregnant women who fall stiffly with fetal Qi rushing to the heart, there is a miraculous Crab Claw Decoction for dead fetus retention, or twins where one dies and one lives; taking it expels the dead and protects the living. Use one sheng of crab claws, two chi of Gan Cao (Licorice Root), and ten dou of flowing water from the east. Boil with reed fire until reduced to two sheng, filter dregs, add three liang of genuine E Jiao (Donkey-hide Gelatin), melt, and take at once or divide into two doses. If the patient is too weak to swallow, force-feed to revive. Crab nature is cold and disperses blood heat pathologies, suitable for traumatic injuries with blood heat stasis. Contraindicated for those with cold coagulation of blood, spleen-stomach cold diarrhea, abdominal pain preferring warmth, and aversion to cold. Crabs with single pincers, single eyes facing each other, six legs with four feet having belly hair, bones in the abdomen, star spots on the back, spotted feet, and red eyes are all toxic and inedible. Their poison is resolved by winter melon juice, Zi Su (Perilla Leaf), garlic and fermented soybean paste, or reed root juice. Do not eat with persimmons or Jing Jie (Schizonepeta), as this triggers cholera and wind movement; Mu Xiang (Aucklandia Juice) resolves this.
Crab disperses blood, resolves knots, benefits Qi, nourishes sinews, clears chest heat and irritability, removes facial swelling and deviation, cures lacquer dermatitis, transforms phlegm, reconnects sinews and bones making sinews join. Patients with wind diseases relapse after ingestion. Pregnant women eating it causes transverse presentation. Crab shells close pediatric fontanelles; claws induce abortion in women. Crushed fresh crab applied externally treats erysipelas (Chi Bai You Zhong). As food, do not eat excessively as it triggers sores and moves Qi. Do not feed crab to children, chickens, or dogs. Seahorses belong to this category; males and females do not separate, heads resemble horses, bodies... spread nets on the water surface. Mainly induces delivery and facilitates birth, a holy medicine for dystocia. Promotes yang erection without flaccidity, assists sexual techniques and spring formulas. Shui Mu (Sea Cucumber/Jellyfish context implies specific marine organism, here likely referring to a jellyfish-like entity or sea cucumber depending on interpretation, but text says "Hai Chong" often meaning jellyfish or similar gelatinous marine life in ancient texts, literally "Sea Heavy/Weight") is also named Hai Chong, abundant in the East Sea, shaped like white foam, swimming relying on shrimp as eyes. Mainly treats postpartum consumption and blood coagulation in women, and pediatric wind diseases with fire-dan toxin.
