服食、使发不白、故本经有自还神化之称。）皂荚水洗净。入罐固 。存性。
补阴。
味甘、咸，性平。能益精，滋润脏腑，止住烦渴。生长于温州的海泥中，形状像车螯但较扁平。经常吐出一寸多长的肉，形状类似舌头，因此得名。
（屠本畯说：这是沙蛤上面的肉，产于吴航，形状像蛤蜊但更大更长，有一块白色的舌状物，名叫西施舌，《闽部疏》说：海味出产于东四郡的，以西施舌为第一，牡蛎次之。西施舌，原本名叫车蛤，因为美味而得名，产于长乐湾中。）
泻湿热。
味咸，性大寒。煎汤外洗，对鹤膝风有效。煅烧后研成粉末，涂抹在湿烂疮上效果神奇。（《岭表录异》记载：海月，广东人叫它膏药，由两片合而成形，壳是圆的，中间非常莹滑洁白，光照下像云母一样。壳内有小肉，像蚌蛤，腹中有蟹子，非常小。饿了蟹就出来吃食，蟹吃饱了它也饱。靠近火烤，蟹就会跑出来，离开肠腹，立刻死亡；或者生剖开，蟹子还活在腹中，不久也会死。屠本畯说：海月形状圆如月亮，也叫蛎镜，当地人常磨砺它的壳，使其通透明亮，像鱼鳞一样排列用来覆盖天窗，岭南称之为海镜，又叫明瓦。按此即海月的壳，一名玳瑁，郭璞所说的“腹蟹”，谢灵运诗中有“挂席拾海月”的诗句就是指的这个。李时珍把它当作江瑶柱，是错误的。）以上属于蛤蚌类。
又名血余。补阴。
味苦，性平。入足少阴肾经、足厥阴肝经。（肾、肝。）补阴消瘀，治疗各种血病。（能去除心窍的血，所以也能治疗惊痫。）
血痢、血淋、舌出血（用茅根汤送服）、鼻出血（吹入鼻腔）。小儿惊热。（与鸡蛋黄一起煎汁服用，鸡蛋能去除风痰。）配合其他药物煎膏，凉血，去瘀生新长肉。胎发尤其好。补益衰败枯竭。（《内经》说：肾是精的储藏所，其荣华表现在头发，是髓之海，头发是脑的荣华。脑髓减少则头发变白。李时珍说：头发是血的剩余，埋在土中千年不腐烂，用火焚烧它，凝结成血质，煎煮到干枯，仍有液体流出。误吞入腹，会化为症虫。炼制服用，能使头发不白，所以《本经》有“自还神化”的称号。用皂荚水洗净，装入罐中密封固封，存性。）
Tonifies Yin.
Sweet, salty, and neutral in nature. Benefits essence, moistens the zang-fu organs, and relieves thirst and restlessness. Grows in the sea mud of Wenzhou, resembling a clam (Che'ao) but flatter. It often protrudes flesh over an inch long, resembling a tongue, hence the name.
(Tu Benjun stated: This is the flesh of the sand clam, produced in Wuhang, resembling a clam but larger and longer, with a white tongue-like part, named Xishishe. *Minbu Shu* states: Among seafood from the four eastern commanderies, Xishishe is ranked first, followed by oysters. Xishishe was originally called Chege, named for its deliciousness, and produced in Changle Bay.)
Drains damp-heat.
Salty and very cold in nature. Decocted as a soup, washing externally is effective for knee-crab disease (He Xi Feng). Calcined and ground into powder, applied topically to weeping ulcers with miraculous effect. (*Lingbiao Luyi* records: Haiyue, known as "plaster" by people in Guangdong, consists of two halves forming a shape; the shell is round, internally very smooth and white like mica. Inside the shell is small flesh like a mussel or clam, containing tiny crabs in its belly. When hungry, the crab comes out to eat; when the crab is full, it is also full. Approaching with fire causes the crab to flee, leaving the intestines and abdomen, dying immediately; or if dissected raw, the crab lives in the belly but dies shortly after. Tu Benjun stated: Haiyue is round like the moon, also called Li Jing. Locals polish its shells to make them transparent, arranging them like scales to cover skylights. In Lingnan, it is called Haijing or Mingwa. This is the shell of Haiyue, also known as Dai Mao. Guo Pu referred to it as "crab in the belly," and Xie Lingyun's poem mentioning "hoisting sails to gather Haiyue" refers to this. Li Shizhen mistakenly identified it as Jiangyao Zhu.) The above belong to the category of clams and mussels.
Also known as Xueyu. Tonifies Yin.
Bitter and neutral in nature. Enters the Foot-Shaoyin Kidney Meridian and Foot-Jueyin Liver Meridian. (Kidney, Liver.) Tonifies Yin and resolves stasis, treating various blood disorders. (Can remove blood from the heart orifices, thus also treating fright and epilepsy.)
Blood dysentery, bloody strangury, bleeding from the tongue (taken with Mugwort Root Decoction), epistaxis (snuffed into the nose). Pediatric fever due to fright. (Decocted with egg yolk; eggs can dispel wind-phlegm.) Combined with other herbs to decoct into a paste, cools blood, removes stasis, and promotes tissue regeneration. Fetal hair is particularly effective. Tonifies decline and depletion. (*Neijing* states: The Kidney stores essence, its luster manifests in the hair; it is the Sea of Marrow, and hair is the luster of the brain. When brain marrow decreases, hair turns white. Li Shizhen said: Hair is the surplus of blood. Buried in soil for a thousand years without decay. Burned with fire, it condenses into a blood-like substance. Boiled until dry, liquid still exudes. Swallowed accidentally, it transforms into abdominal masses. Refined and taken orally, it prevents graying of hair, hence the *Shennong Bencao Jing* calls it "returning to divine transformation." Washed clean with soap pod water, placed in a jar, sealed tightly, and preserved for medicinal use.)
