名
【鸭肪】
味甘，无毒。主治风虚证，寒热往来。
白鸭屎：别名鸭通。主要功效为杀灭石药毒，解除结滞束缚，消散蓄积之热。
鸭肉：具有补益虚损，清除内热，调和脏腑功能，通利水道的作用。
这里的“鸭”分为家鸭和野鸭，前代《神农本草经》中记载的是雁脂（雁的脂肪），其治疗作用略有不同，此处所述则专门指家鸭的脂肪。
【牡蛎】
味咸，性平、微寒，无毒。主治伤寒病，寒热往来，温疟发作时战栗发抖，惊恐愤怒之气，解除肢体拘挛缓急，鼠瘰（颈部淋巴结结核），女子赤白带下。去除关节间留滞之热，清退营卫虚弱所致忽冷忽热的虚热，消除烦闷胀满，止汗，治疗心痛气结，生津止渴，祛除陈旧瘀血，收敛大肠小肠，止住大小便失禁，治疗遗精滑泄，喉痹，咳嗽，心胁下痞塞发热。长期服用可强健骨节，驱除邪祟，延年益寿。别名蛎蛤，又名牡蛤。产于东海池泽之中。采集没有固定时间。（贝母为其引经药，配伍甘草、牛膝、远志、蛇床子效果良好，忌与麻黄、吴茱萸、辛夷同用。）
传说牡蛎是百岁老雕所化，以十一月采集为佳。使用时需去掉肉质部分，经过二百天处理成粉状。现在出产于东海，永嘉、晋安两地所产者品质较好。道家方术中认为向左顾盼的是雄牡蛎，所以名叫牡蛎；向右顾盼的是雌牡蛎。它们附着在石头上生长，通常口朝上，将其举起腹部向南观察，若口部斜向东则是正品。也有人说以尖头朝向左侧为左顾盼者，但不清楚哪种说法正确。一般以大个者为佳。另外广州出产，南海地区也是如此，只是多为右顾盼者而不被使用。炼丹方术中使用泥锅时，都要除去甲壳边缘，只取内部如粉末状的物质。世人使用也是如此，海边人都用其煮盐锅，耐水火而不破裂渗漏。
【魁蛤】
味甘，性平，无毒。主治痿痹证，泄泻痢疾，大便脓血。别名魁陆，又名活东。产于东海，形状正圆且两头中空，表面有纹理，采集没有固定时间。
形状像纺锤，细小狭长，外面有纵横交错的纹理，说是由老蝙蝠变化而来，药用价值较少。而《神农本草经》中记载的海蛤，别名……
[Anatum Fat]
Sweet in taste, non-toxic. It treats wind deficiency syndromes and alternating chills and fever.
White duck feces: Also known as Yatong (Duck Pass). It primarily neutralizes the toxicity of mineral drugs, resolves stagnation and binding, and dissipates accumulated heat.
Duck meat: Tonifies deficiency, clears internal heat, harmonizes the Zang-Fu organs, and promotes the free flow of water passages.
The term "duck" here refers to both domestic and wild ducks. The earlier *Shennong Bencao Jing* recorded goose fat (fat from geese), which has slightly different therapeutic effects; the description here specifically refers to the fat of domestic ducks.
[Ostreae Concha]
Salty in taste, neutral and slightly cold in nature, non-toxic. It treats cold damage diseases, alternating chills and fever, shivering during the onset of warm malaria, fright and anger qi, relieves limb stiffness and flaccidity, scrofula (tuberculous lymphadenitis of the neck), and red and white leukorrhea in women. It eliminates lingering heat in the joints, clears deficiency heat of Ying and Wei (nutritive and defensive levels) characterized by irregular temperature fluctuations, relieves irritability and fullness, stops sweating, treats heart pain with qi stagnation, generates fluids to stop thirst, removes old blood stasis, astringes the large and small intestines, stops diarrhea and urinary incontinence, treats seminal emission, bi-syndrome of the throat (sore throat with obstruction), cough, and epigastric/hypochondriac stuffiness with heat. Long-term consumption strengthens bone and joints, expels evil spirits, and prolongs life. Also known as Lige, or Mu Ge. It grows in the pools and marshes of the East Sea. It can be collected at any time. (Fritillariae Bulbus is its guiding herb; it works well when combined with Glycyrrhizae Radix, Achyranthis Bidentatae Radix, Polygalae Radix, and Cnidii Fructus; it is incompatible with Ephedrae Herba, Evodiae Fructus, and Magnoliae Flos.)
It is said that Ostreae Concha is transformed from an eagle that has lived for a hundred years. It is best collected in the eleventh lunar month. The flesh should be removed, and it takes two hundred days to process into powder. Currently, it is produced in the East Sea, with those from Yongjia and Jin'an being of good quality. In Daoist formulas, the one facing left is considered male, hence named "Mu Li" (Male Oyster); the one facing right is female. They attach themselves to rocks, usually with the mouth facing upward. When held up with the abdomen facing south, if the mouth slants toward the east, it is authentic. Some say the pointed end indicates the left-facing side, but it is unclear which view is correct. Generally, larger shells are preferred. They are also produced in Guangzhou and the South Sea region, but mostly the right-facing ones are not used. In alchemical formulas using clay crucibles, the shell edges are removed, and only the inner powdery substance is taken. This method is also used by common people; coastal residents use it to line salt-boiling pots, which withstand fire and water without cracking or leaking.
[Qu Ge]
Sweet in taste, neutral in nature, non-toxic. It treats flaccidity and bi-syndromes, diarrhea and dysentery, and pus and blood in the stool. Also known as Kuilu, or Huodong. It grows in the East Sea. It is perfectly round with hollow ends and has patterns on its surface. It can be collected at any time.
Its shape resembles a spindle, small and narrow, with longitudinal and transverse textures on the outside. It is said to be transformed from an old bat, and its medicinal use is minimal. The *Shennong Bencao Jing* mentions Hai Ge (Sea Clam), also known as...
