蛤蜊（文蛤）禀受水中的阴气而生，味道咸，性质寒冷，无毒。归入足阳明胃经。五脏都属于阴，凡是获得水气之阴的事物，其性质滋润且能助生津液，所以能够滋润五脏、止住消渴、增进食欲。咸味能入血分并软化坚硬之物，所以主治妇女的血块以及因老积癖引起的寒热症状。煮熟食用能解酒，也是因为它进入阳明经从而清除热邪。然而，人们服用丹石类药物后，会导致腹部结聚疼痛。对于气虚引起的水肿，可用大蒜十个捣成泥状，加入蛤粉制成梧桐子大小的药丸，每次饭前用白开水送服二十丸，服完后，小便排出数桶水即可痊愈。对于白浊和遗精，可用蛤粉一斤，黄柏用蜜炙过的一斤，研为细末，用水泛丸如梧桐子大，每次服用一百丸，空腹时以酒送服，每日两次，这是因为蛤粉味咸能补肾阴，黄柏味苦能降心火并坚固肾气。
蛤蜊壳，能去除老积癖、顽痰和血块，并能迅速清热。蛤蜊肉煮熟食用能开胃、滋润五脏、止消渴、解酒毒，治疗老积癖引起的寒热及妇女血块。蚬（河蚌类小贝）体型小而色黑，其肉能解酒毒和湿毒，其黄色部分能去除热气、时行疫病引起的目赤肿痛，开胃脘，压制丹石毒性，促进乳汁下行，通利小便，生捣汁液涂抹可治秃疮。
牡蛎得海气凝结而成，味道咸，性质微寒，无毒。归入肝、胆、肾三经。具有清热、软化坚硬、化痰散结、收敛固脱的功效。虽然主治病症很多，但因其咸味独胜，主要发挥走肾、收敛涩滞的作用。与生地黄、黄芪、龙眼肉、五味子、酸枣仁、麦门冬、白芍药、茯神、黄柏、当归同用，可治疗心肾虚损引起的盗汗；与黄柏、五味子、地黄、山茱萸、枸杞子、车前子、沙苑蒺藜、莲须、杜仲同用，可治疗梦遗滑精；加牛膝则可兼治赤白浊。与地黄、黄柏、阿胶、木耳、炒黑的香附、白芍药、地榆、麦门冬、续断、青蒿、鳖甲、蒲黄同用，可止住妇女崩中下血及赤白带下。对于虚劳盗汗，用牡蛎粉、麻黄根、黄芪等分为末，每次服用二钱，水煎服。对于水病囊肿，用牡蛎二两、干姜炮制一两，研细，用冷水调匀外敷，片刻后囊皮发热如火，干了再敷，待小便通利即愈。另一方法是用葱汁和白面调和。小儿不用干姜。对于男女瘰疬，用牡蛎粉四两，玄参末三两、甘草一两，用面糊制成梧桐子大小的药丸，每次三十丸，酒送服，每日三次，服完可除根，无论是否破溃均有效。对于月经不止，将牡蛎研细末，用醋调和成团，再研成末，用米醋调艾叶末熬膏，制成梧桐子大小的药丸，每次用醋汤送服四五十丸。

Wenli (Clam) is born by inheriting the Yin Qi of water. Its taste is salty, its nature is cold, and it is non-toxic. It enters the Foot-Yangming Stomach Meridian. The Five Zang Organs all belong to Yin. Anything that obtains the Yin of Water Qi has a moistening nature and assists in generating body fluids; therefore, it can moisten the Five Zang Organs, stop Xiao Ke (wasting-thirst syndrome), and stimulate appetite. Salty flavor can enter the Blood level and soften hardness; thus, it mainly treats blood masses in women and chills and fever caused by old accumulations (Lao Pi). Boiled consumption can sober up intoxication because it enters the Yangming Meridian and eliminates heat. However, after people consume Dan Shi (mineral pills), it causes abdominal knotting and pain. For edema due to Qi deficiency, use ten cloves of garlic mashed into a paste, add Ge Fen (Clam Shell Powder) to form pills the size of wu zi (loquat seeds). Take twenty pills before each meal with plain warm water. After finishing the course, urinating several buckets of urine will lead to recovery. For Bai Zhuo (white turbid discharge) and nocturnal emission, use one jin of Ge Fen and one jin of Huang Bo (Phellodendron Bark) honey-fried, grind into powder, make water pills the size of wu zi. Take one hundred pills at an empty stomach with wine, twice daily. This is because Ge Fen is salty and can tonify Kidney Yin, while Huang Bo is bitter and descends Heart Fire to strengthen the Kidney.
Ge Qiao (Clam Shell) can remove old accumulations, stubborn phlegm, and blood masses, and clears heat with immediate effect. The meat, when boiled and eaten, can stimulate appetite, moisten the Five Zang Organs, stop wasting-thirst, resolve alcohol toxicity, treat chills and fever from old accumulations, and women's blood masses. Xian (Small freshwater clam) is small and black. Its meat resolves alcohol and dampness toxicity. Its yellow part removes heat qi, eye redness from seasonal epidemics, stimulates the epigastrium, suppresses Dan Shi toxicity, promotes lactation, promotes urination, and raw juice applied externally treats alopecia.
Muli (Oyster Shell) forms by condensing sea Qi. Its taste is salty, its nature is slightly cold, and it is non-toxic. It enters the Liver, Gallbladder, and Kidney meridians. It is used for clearing heat, softening hardness, resolving phlegm, dissipating nodules, and astringing to prevent collapse. Although it treats many conditions, its salty flavor is predominant, so its main functions are entering the Kidney and astringent actions. Combined with Sheng Di Huang (Rehmannia Root), Huang Qi (Astragalus Root), Long Yan Rou (Longan Aril), Wu Wei Zi (Schisandra Fruit), Suan Zao Ren (Ziziphus Seed), Mai Men Dong (Ophiopogon Tuber), Bai Shao Yao (White Peony Root), Fu Shen (Poria with Hostwood), Huang Bo, and Dang Gui (Angelica Sinensis), it treats night sweats due to Heart and Kidney deficiency. Combined with Huang Bo, Wu Wei Zi, Di Huang, Shan Zhu Yu (Cornus Fruit), Gou Qi Zi (Goji Berry), Che Qian Zi (Plantago Seed), Sha Yuan Ji Li (Astragalus Complanatus Seed), Lian Xu (Lotus Stamen), and Du Zhong (Eucommia Bark), it treats dream emission and seminal leakage. Adding Niu Xi (Achyranthes Root) also treats red and white turbidity. Combined with Di Huang, Huang Bo, E Jiao (Donkey-hide Gelatin), Mu Er (Wood Ear Mushroom), Chao Hei Xiang Fu (Cyperi Rhizoma stir-baked black), Bai Shao Yao, Di Yu (Sanguisorba Root), Mai Men Dong, Xu Duan (Dipsacus Root), Qing Hao (Artemisia Annua Herb), Bie Jia (Tartar Testudinis Carapax), and Pu Huang (Typha Pollen), it stops Bing Zhong Xia Xue (metrorrhagia) and red-white leukorrhea in women. For deficiency consumptive night sweats, equal parts Muli Fen, Ma Huang Gen (Ephedra Root), and Huang Qi are ground into powder. Take two qian per dose, decocted in water. For hydrocele cysts, use two liang of Muli and one liang of Pao Gan Jiang (Prepared Ginger), finely ground, mixed with cold water for external application. The scrotum becomes hot like fire shortly; reapply when dry. Recovery occurs when urination improves. Another method uses green onion juice and wheat flour for mixing. Children do not use Gan Jiang. For Luo Li (scrofula) in men and women, use four liang of Muli Fen, three liang of Xuan Shen (Scrophularia Root), and one liang of Gan Cao (Licorice Root), made into pills with wheat paste the size of wu zi. Take thirty pills with wine, three times daily. Finishing the course eradicates the root, effective whether broken or unbroken. For continuous menstruation, grind Muli into fine powder, knead into a ball with vinegar, regrind into powder, mix with Ai Ye (Mugwort Leaf) powder boiled in rice vinegar to make a paste, form pills the size of wu zi. Take forty to fifty pills with vinegar-infused water per dose.
Muli Fen (Oyster Shell Powder) specifically enters the Kidney Meridian. Salt processing helps eliminate sores, prevents enuresis and seminal emission, astringes Yin sweat and night sweats, dissolves old phlegm and old blood, and treats Qi-deficiency leukorrhea. It treats Shu Lou (scrofula), Hou Bi (sore throat), cough, irritability, chest fullness, heart pain, and Qi stagnation. It can stop thirst, astringe the intestines, dissipate Ying (goiter), and clear turbid urine. Overall, it is sour, astringent, and slightly cold, serving as an agent for resolving phlegm, softening hardness, astringing, and consolidating. However, long-term use may damage Middle Jiao Yang causing internal cold.
