桑螵蛸

桑螵蛸是螳螂在桑树枝上产下的卵鞘，古人特别看重'生于桑上'这一细节，认为桑木得四时之正气,螳螂卵鞘附着其上,便同时兼得了虫性与木气的双重滋养。

李时珍在《本草纲目》中特别强调，唯有采自桑树上的螳螂卵鞘方称'桑螵蛸'，若在其他树上采得，则药力大减，这份对'附生之木'的严格要求,体现了本草学取材的精细讲究。

Mantis egg case is the ootheca that the praying mantis deposits upon mulberry branches. Ancients placed special importance on this detail of 'growing upon the mulberry,' believing that mulberry wood receives the correct qi of the four seasons, so a mantis egg case attached to it gains the dual nourishment of both insect nature and wood qi.

Li Shizhen specifically emphasized in the Compendium of Materia Medica that only mantis egg cases gathered from mulberry trees may be called 'sang piao xiao'; if collected from other trees, their potency is greatly diminished. This strict requirement regarding the 'host tree' reflects the meticulous care taken in sourcing materials for materia medica.

桑螵蛸善治小儿遗尿、成人尿频遗精，古方'桑螵蛸散'配伍龙骨、龟甲等固涩之品,专治肾气不固所致的诸般滑脱之症,是补肾缩尿的经典配伍。

民间常用桑螵蛸炖汤给夜尿频多的老人调养，这份'以固为补'的用药思路,与螳螂产卵鞘'一巢护数百卵'的自然特性遥相呼应,颇具取象比类的巧思。

Mantis egg case excels at treating childhood bedwetting and adult frequent urination or seminal emission. The classical formula 'Sangpiaoxiao San' combines it with dragon bone and tortoise shell—astringent substances—specifically treating various forms of leakage caused by unsecured kidney qi, a classic pairing for tonifying the kidney and reducing urination.

Folk practice often stews mantis egg case into soup for elderly people troubled by frequent nighttime urination. This approach of 'tonifying through securing' echoes, at a distance, the mantis's natural habit of 'one case guarding hundreds of eggs'—a clever instance of reasoning by symbolic correspondence.

螳螂产卵时会分泌一种特殊泡沫状物质包裹卵粒，遇空气迅速凝固成坚韧的卵鞘,内部结构层层分隔,既能保温又能防御天敌啄食,堪称昆虫界精妙的'育儿仓'设计。

一枚卵鞘中往往藏有上百枚卵粒,来年春天幼螳螂破壳而出的场景蔚为壮观，这份'一鞘百子'的繁衍智慧,让古人对桑螵蛸生发出'固精多子'的联想。

When laying eggs, the mantis secretes a special foam-like substance to encase the eggs; upon contact with air, it rapidly hardens into a tough ootheca with internally layered, compartmented structure—retaining warmth while defending against predators. It stands as an ingenious 'nursery chamber' design within the insect world.

A single egg case often conceals over a hundred eggs; the scene of young mantises emerging the following spring is a spectacular sight. This reproductive wisdom of 'a hundred offspring from one case' led ancients to associate mantis egg case with the notion of 'securing essence and fostering fertility.'

深秋初冬，桑叶落尽，正是采集桑螵蛸的最佳时节，采药人穿梭于光秃的桑园之间,在枝杈间寻觅那一枚枚灰褐色的卵鞘,须得仔细辨认才能与树皮区分开来。

采得的卵鞘须蒸透以杀死其中虫卵，方可入药，否则来年春天卵鞘中孵出的幼螳螂便会破壳而出,这份炮制工艺中的巧思,兼顾了药效与实用的双重考量。

In late autumn and early winter, when mulberry leaves have fallen, is the prime season for gathering mantis egg cases. Herb gatherers move through the bare mulberry groves, searching the branches for grayish-brown egg cases, which require careful discernment to distinguish from the bark itself.

Gathered egg cases must be thoroughly steamed to kill the eggs within before they can be used medicinally; otherwise, young mantises would hatch and break free the following spring. This ingenuity in the processing method balances both medicinal efficacy and practical necessity.

本草文献中记载桑螵蛸有'团螵蛸''长螵蛸''黑螵蛸'三种，分别对应大刀螳、小刀螳、巨斧螳等不同螳螂种类所产的卵鞘,形态与药力略有差异。

这份对'同一药材、不同来源'的细致区分,展现出本草学并非笼统的经验总结,而是建立在长期细致观察之上的系统知识体系。

Materia medica literature records three kinds of mantis egg case—'round egg case,' 'long egg case,' and 'black egg case'—corresponding respectively to the oothecae produced by different mantis species such as the Chinese mantis, the narrow-winged mantis, and the giant mantis, with slight variations in form and potency.

This careful distinction of 'the same medicine, different sources' shows that materia medica is not a vague summary of experience, but a systematic body of knowledge built upon prolonged, meticulous observation.
