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.)
