蛤蚧，味咸，气平，有小毒。主肺虚声咳无休，治肺痿，定喘止嗽，益精血，助阳道，
血咯
不已，逐传尸痨疰，祛着体邪魅，仍通月经，更利水道。至神功用，全在于尾，尾损则无用
也。然亦必得人参、麦冬、五味子、沙参乃奇。
蛤蚧生于西粤者佳，夜间自鸣声至八九声者为最胜。捕得之须护其尾，尾伤即有毒，所
断之
尾反可用也。
蛤蚧，善能固气，含其尾急趋，多不动喘，故止喘实神。
蝼蛄，即土狗也。味咸，气寒，无毒，《本草》言其利水，宜分上下左右，然亦不必拘
也。
通身用之以利湿，神效。此物兼能接续骨伤，治口疮乳毒亦效，但不宜与虚人，因其性急过
利也。
鳗鱼，味甘，气寒，有毒。杀诸虫，调五脏，除五痔，逐腰背之风湿浸淫，治男女骨蒸
痨瘵
，兼疗香港脚，产户虫疮，并崩漏不断者，多食最效。骨烧薰床上衣箱，百虫皆死。非补益之
药，然食之杀虫，使尸虫尽绝。痨瘵重生，又不可为，非补也。大约于丸散中，同补阴药修
合为佳耳。
鳗鱼治痨瘵，自是杀虫，然必须淡食为佳。盖咸则尽入于肾中，而淡则无经不达也。
或问鳗鱼亦杀痨虫，何以不同鳖方共治？曰∶鳖与鳗，虽同是杀虫之物，而性各别，鳖喜攻
入，而鳗喜攻出也。虽二物亦可同用以出奇，然用之以治骨蒸，宜分用而不宜同用。一欲出
一欲入，两相拂意，反相忘其杀虫矣，况骨内之虫，驱外出而杀之，不若攻入内而尽诛之
也
。故用鳗又不若用鳖之更胜。倘单用鳗鱼作食以杀虫，此鳖又不若鳗鱼之功也。盖鳖肉但补
而不攻耳。
或问鳗鱼杀虫而不补精，何以能愈骨蒸之病，岂杀虫即可以愈骨蒸乎？曰∶鳗鱼实只杀
痨虫
，而骨蒸之病可全愈者，必胃健能食，有滋补之味也。倘胃气不开，又无填精降火之药，徒
恃鳗鱼之杀虫也，亦何益乎。
蛤蚧，味道咸，性质平和，有小毒。主治肺虚导致的咳嗽不止，治疗肺痿，平息喘息、停止咳嗽，补益精血，助益阳气，对于咯血不止有效，驱逐传尸痨疰（一种具有传染性的慢性消耗性疾病），祛除附着于身体的邪气魅惑，同时能疏通月经，更利于水道通畅。其神妙的功效，全在于尾部，尾部受损则失去效用。然而，也必须配合人参、麦冬、五味子、沙参使用才能发挥奇效。
产于西粤（今广西一带）的蛤蚧品质最佳，夜间鸣叫声音达到八九声的为最上乘。捕捉时必须保护其尾部，尾部受伤即产生毒性，但折断下来的尾部反而可以使用。
蛤蚧善于固护元气，含着它的尾巴急走，大多不会气喘，所以止喘效果确实神奇。
蝼蛄，就是土狗。味道咸，性质寒，无毒。《本草》说它有利水作用，适宜分上下左右部位使用，但也不必拘泥于此。
全身入药以利用其利湿功效，效果神妙。此物兼能接续骨伤，治疗口疮和乳部毒疮也有效，但不宜用于体质虚弱的人，因为其药性急迫且利水太过。
鳗鱼，味道甘，性质寒，有毒。能杀灭各种寄生虫，调和五脏，消除五种痔疮，驱逐腰背部的风湿浸淫之邪，治疗男女骨蒸劳瘵（阴虚发热、形体消瘦的慢性消耗性疾病），兼治香港脚（脚气病）、产户虫疮以及崩漏不止者，多吃最为有效。将鳗鱼骨烧成灰熏蒸床上的衣物箱柜，百虫皆死。它不是补益类药物，但食用它能杀虫，使体内的尸虫彻底绝灭。如果患痨瘵的人重新生病，就不能再这样处理了，这并非补益之法。大约将其制成丸散，与补阴药配合使用为佳。
鳗鱼治疗痨瘵，主要是靠杀虫，但必须清淡饮食为佳。因为咸味药物会全部进入肾中，而淡味药物则无处不到。
有人问：鳗鱼也能杀痨虫，为什么不与鳖方共同治疗？回答说：鳖与鳗鱼，虽然都是杀虫之物，但性质各异，鳖喜欢攻入体内，而鳗鱼喜欢攻出体外。虽然这两样东西也可以同用以求出奇制胜，但用来治疗骨蒸时，适宜分开使用而不宜同用。一个想排出，一个想攻入，两者相互抵触，反而忘记了杀虫的作用，况且对于骨内的虫子，驱赶出去再杀死，不如攻入体内彻底诛杀更好。所以使用鳗鱼不如使用鳖更胜一筹。倘若单用鳗鱼作为食物来杀虫，这时鳖又不若鳗鱼的功效大。因为鳖肉只补而不攻。
有人问：鳗鱼杀虫而不补精，怎么能治愈骨蒸的病？难道杀虫就可以治愈骨蒸吗？回答说：鳗鱼实际上只是杀死痨虫，而骨蒸的病能完全痊愈，必定是因为胃气强健能够进食，有滋补的味道。如果胃气不开，又没有填精降火的药物，仅仅依靠鳗鱼的杀虫作用，又有什么益处呢。
Gejie (Gekko gecko), salty in flavor, neutral in nature, slightly toxic. It primarily treats incessant cough due to Lung deficiency, manages Lung萎 (Lung atrophy/flaccidity), calms asthma and stops coughing, benefits essence and blood, assists Yang function, is effective for persistent hemoptysis, expels Chuan Shi Lao Zhu (a contagious chronic consumptive disease), dispels pathogenic influences adhering to the body, unblocks menstruation, and promotes the smooth flow of water passages. Its miraculous efficacy lies entirely in its tail; if the tail is damaged, it becomes useless. However, it must be combined with Renshen (Ginseng Root), Maidong (Ophiopogon Tuber), Wuweizi (Schisandra Fruit), and Shashen (Glehnia Root) to achieve extraordinary results.
Gejie produced in Western Yue (modern Guangxi) is superior. Those that call eight or nine times at night are considered the best quality. When caught, the tail must be protected; a damaged tail becomes toxic, but the severed tail can still be used.
Gejie excels at consolidating Qi. Holding its tail while moving quickly often prevents panting, making its anti-asthmatic effect truly miraculous.
Lougu (Mole Cricket), also known as Tu Gou. Salty in flavor, cold in nature, non-toxic. *Ben Cao* states it promotes diuresis, suitable for use targeting upper/lower or left/right areas, though one need not be rigid about this. Using the whole body to promote dampness removal yields miraculous effects. This substance also aids in healing bone injuries and is effective for treating mouth ulcers and breast toxins, but it is unsuitable for patients with deficiency constitutions due to its rapid and overly draining nature.
Man Yu (Eel), sweet in flavor, cold in nature, toxic. It kills various parasites, harmonizes the Five Zang organs, eliminates five types of hemorrhoids, expels wind-dampness infiltrating the waist and back, treats Gu Zheng Lao Zhai (bone-steaming consumptive disease in both men and women), and concurrently treats Hong Kong Jiao (podagra/foot qi), perineal parasitic sores, and continuous metrorrhagia. Consuming it in large quantities is most effective. Burning eel bones to fumigate beds, clothes, and chests kills all insects. It is not a tonic herb, but eating it kills parasites, ensuring the complete eradication of corpse-worms. If a patient with Lao Zhai were to relapse, such treatment would be inadvisable, as it is not tonifying. Generally, preparing it into pills or powders and combining it with Yin-nourishing herbs is optimal.
In treating Lao Zhai, Man Yu works primarily by killing parasites, but a light diet is preferred. Salty flavors enter exclusively into the Kidneys, whereas light flavors penetrate everywhere without restriction.
One might ask: Since Man Yu also kills Lao worms, why is it not used together with Bie (Turtle Shell) prescriptions? The answer is: Although Bie and Man Yu are both parasiticidal substances, their natures differ. Bie tends to attack inwardly, while Man Yu tends to attack outwardly. While they can be used together for unexpected results, when treating bone-steaming heat, they should be used separately rather than together. One seeks to expel, the other to invade; these opposing actions conflict and negate their parasiticidal effects. Moreover, driving parasites out from the bone before killing them is inferior to attacking them internally and exterminating them completely. Therefore, using Bie is superior to using Man Yu. However, if using Man Yu alone as food to kill parasites, Bie is less effective than Man Yu, because Bie meat only tonifies without attacking.
One might ask: Man Yu kills parasites but does not nourish essence; how can it cure bone-steaming disease? Does killing parasites equate to curing bone-steaming? The answer is: Man Yu essentially only kills Lao worms. The complete recovery from bone-steaming disease depends on strong Stomach Qi and appetite, providing nourishing value. If Stomach Qi is stagnant and there are no herbs to fill essence and descend fire, relying solely on Man Yu’s parasiticidal action offers no benefit.
