甘平无毒。
发明 蛏生江湖中，与蚌蛤相类。闽人以田种之，谓之蛏田，其肉可为淡干。肠鼻糟之
以充海错，妇人产后虚热宜之。
俗名蚶子，即瓦楞子
肉甘平，壳咸平，无毒。
发明 蚶肉仅供食品，虽有温中健胃之功，方药曾未之及。其壳 灰则有消血块，散痰
积，治积年胃脘瘀血疼痛之功。与鳖甲、虻虫同为消疟母之味，独用醋丸则消胃脘痰积。观
制蚶饼者，以蚶壳灰泡汤搜糯粉则发松异常，软坚之力可知。
一名蜃
咸冷无毒。
发明 车螯是海中大蛤，以其吐气成楼，故名曰蜃。所谓雀入淮为蛤，雉入海为蜃者是
也。其肉解酒毒，消渴；壳治疮肿痈毒，烧赤醋淬为末，同甘草等分酒服，并以醋调敷之，
《日华》法也。
咸平小毒。烧赤捣细如面，以清酒淘过用。白者入气分，紫者入血分，花者兼入
血气。
《本经》主目翳五癃利水道，鬼疰虫毒，腹痛下血。
发明 贝生南海，云南极多，土人用为钱货交易。因其味咸软坚，故《本经》专主目翳
，其治五癃等病，取咸润走血之力。《千金》香港脚丸中用之，专取咸能破坚之意，虽数十年
之疾，靡不克效，以其透入骨空搜逐湿淫之气，和诸药蒸蒸作汗，次第而解也。古方点目用
贝子粉入龙脑少许，有息肉加珍珠末吹点，亦入老翳诸方。紫贝治小儿 疹、目翳。今人用
以砑纸谓之砑蠃，大者曰珂，亦名马轲螺。治目消翳，去筋膜 肉与贝子相类，分紫、白，
灰用之。
甘平无毒。
【发明】蛏子生长在江河湖泊中，外形与蚌蛤相似。福建人采用在田地里养殖的方式培育它，称为“蛏田”，其肉质可以制成淡干品。将肠鼻部分用酒糟腌制以作为海味佳肴，适合产后妇女因虚热引起的不适。
俗名蚶子，即瓦楞子。
肉性甘平，壳性咸平，无毒。
【发明】蚶肉仅作为食品食用，虽然具有温中健胃的功效，但在方药中从未被使用。其贝壳煅烧成灰后，具有消除血块、消散痰积、治疗多年胃脘部瘀血疼痛的功效。它与鳖甲、虻虫一样，属于消除疟母（疟疾形成的肿块）的药物；单独使用醋制丸剂则可以消除胃脘部的痰积。观察制作蚶饼的过程可知，用蚶壳灰浸泡在水中搅拌糯米粉，会使面团异常蓬松，由此可知其软坚散结的力量。
又名蜃。
性咸冷，无毒。
【发明】车螯是海中大型蛤蜊，因为它吐气能形成楼阁状的景象，所以名叫蜃。这就是所说的“麻雀进入淮河变成蛤，野鸡进入大海变成蜃”的情况。其肉质能解酒毒、缓解口渴；贝壳用于治疗疮肿痈毒，将其烧红后用醋淬炼研成粉末，与甘草等量混合用酒送服，并用醋调匀外敷，这是《日华子本草》记载的方法。
性咸平，有小毒。需烧红后捣碎如面粉状，用清酒淘洗后使用。白色入气分，紫色入血分，花斑色兼入气血。
《神农本草经》主治目生翳膜、五种淋证、通利水道，以及鬼疰（慢性传染病）、虫毒、腹痛下血。
【发明】贝子产于南海，云南地区极多，当地人将其作为钱币进行交换交易。因为其味咸能软坚散结，所以《本经》专门用于主治目翳。它治疗五种淋证等疾病，是利用其味咸润下、走血分的特性。《千金方》中的香港脚丸中使用它，专门取其咸能破坚的意思，即使是几十年的疾病，没有不能治愈的，因为它能透入骨空搜逐湿邪之气，配合其他药物使身体蒸蒸发汗，依次解除病邪。古方点眼时使用贝子粉加入少许龙脑，如果有息肉则加入珍珠末吹点，也用于含有老翓的各种方剂中。紫贝用于治疗小儿麻疹、目翳。现在的人用它来打磨纸张，称为“砑蠃”，大的叫做“珂”，也叫马轲螺。治疗眼睛消除翳膜，去除筋膜赘肉，与贝子的功效类似，分为紫色和白色，煅烧成灰后使用。
Sweet and neutral, non-toxic.
[Invention] The razor clam (Chen) grows in rivers and lakes and is similar to mussels and clams. People in Fujian cultivate it in fields, calling it "clam fields," and its meat can be processed into dried salted products. The intestines and siphons are pickled with wine lees to serve as seafood delicacies; it is suitable for postpartum women suffering from deficiency-heat.
Commonly known as Hanz, i.e., Valvatae Concha (Walengzi).
The meat is sweet and neutral; the shell is salty and neutral, non-toxic.
[Invention] Hanz meat is only used as food. Although it has the effect of warming the middle and strengthening the stomach, it has never been used in prescriptions. Its calcined ash has the function of resolving blood stasis masses, dissipating phlegm accumulation, and treating chronic epigastric pain due to blood stasis. It shares the property of eliminating malaria masses (Nuomother) with Bie Jia (Testudinis Carapax et Plastrum) and Meng Chong (Blaberidae), but when used alone as vinegar pills, it resolves epigastric phlegm accumulation. Observing the preparation of Hanz cakes, where Hanz shell ash is soaked in water to mix with glutinous rice flour, causing the dough to become exceptionally fluffy, reveals its powerful softening and hard-resolving capability.
Also known as Shen.
Salty and cold, non-toxic.
[Invention] Che'ao is a large sea clam. It is named Shen because it exhales air that forms tower-like shapes. This refers to the saying "sparrows entering the Huai River turn into clams, pheasants entering the sea turn into Shens." Its meat resolves alcohol toxicity and relieves thirst; its shell treats sores, swelling, and carbuncles. When calcined red, quenched in vinegar, and ground into powder, taken in equal parts with Gancao (Licorice Root) with wine, or applied externally mixed with vinegar, this is the method recorded in *Ri Hua Zi Ben Cao*.
Salty and neutral, slightly toxic. Calcined until red, ground fine like flour, and rinsed with clear wine before use. White shells enter the Qi level; purple shells enter the Blood level; variegated shells enter both Qi and Blood.
*Shennong Bencao Jing* states it primarily treats leukoma (eye opacity), five types of strangury, promotes urination, treats Guizhu (chronic infectious diseases), insect toxins, abdominal pain, and bloody stool.
[Invention] Beizi (Concha Meretricis) originates from the South Sea and is abundant in Yunnan, where locals use it as currency for trade. Because its salty taste softens hardness, *Bencao Jing* specifically uses it for leukoma. In treating the five types of strangury, it utilizes the moistening and blood-invigorating power of salt. It is used in *Qianjin Fang*'s Hongjiao Wan (Hongjiao Pill), specifically for its ability to break firmness through saltiness. Even diseases lasting decades can be cured because it penetrates bone cavities to search out damp pathogenic qi, and when combined with other herbs, induces steaming sweat to resolve pathogens sequentially. Ancient eye-drop formulas used Beizi powder with a small amount of Longnao (Borneolum Syntheticum); if polyps were present, Zhenzhu Mo (Pearl Powder) was added for insufflation; it is also included in formulas for old leukoma. Zi Bei (Purple Clam Shell) treats pediatric measles and leukoma. Currently, people use it to polish paper, called "Ya Luo"; larger ones are called Ke, also known as Ma Ke Luo Snail. Treating eye leukoma and removing membrane overgrowths, its efficacy is similar to Beizi. It is divided into purple and white varieties and used after calcination.
