（卵生）入肾补火益精
雄蚕蛾（专入命门。）即二蚕所出之雄者也。味咸性温。其性最淫。出茧便媾。诸书皆
载能起
阴痿。益精强志。敏于生育。交接不倦。并敷诸疮灭瘢。止尿血。暖肾。盖取其性淫助阳。
咸温入肾之功耳。是以千金方治丈夫阴痿不起用此。一夜每服一丸。（以蚕蛾二升去翅足。
微火灼黄为末。蜜丸如梧桐子大。酒下。）以菖蒲止之。但此止为阳痿求嗣而见。若使阴虚
火盛而用此为淫戏之术。则阴愈竭而火益盛。欲不速毙。其可得乎？故古补方多不具载。恐
人借此以为斫丧之具也。取未交雄者佳。蚕退纸烧灰。可敷走马牙疮。（蚕退纸灰入麝和蜜
。敷走马牙疳。加白矾妙。）并治邪祟发狂悲泣。

雄蚕蛾（专门进入命门经。）就是两只蚕交配后产卵所孵出的雄性蚕蛾。味道咸，性质温。它的性情最淫欲旺盛。一出茧便进行交配。各种书籍都记载它能治疗阳痿不起，增加精气，增强意志，提高生育能力，性交不知疲倦。并且外敷可治疗各种疮疡，消除疤痕，止尿血，温暖肾脏。大概是利用它性淫以助阳、味咸性温以入肾的功效罢了。因此，《千金方》治疗男子阳痿不起时使用此药。每晚服用一丸。（用二升蚕蛾，去掉翅膀和脚，用微火烤至微黄，研成粉末，用蜂蜜制成梧桐子大小的丸剂，酒送服。）并用菖蒲来节制。但这仅适用于因阳痿求子而见的情况。如果是阴虚火旺的人将其作为纵欲的手段，那么阴液会更加枯竭，火势更加旺盛，想要不迅速死亡，可能吗？所以古代的补益方剂大多不详细记载此药，是担心人们借此作为损耗身体的工具。取未交配的雄蚕蛾为佳。蚕退纸烧成灰，可以外敷治疗走马牙疳。（将蚕退纸灰与麝香混合，加蜂蜜，外敷治疗走马牙疳，加入白矾效果更好。）并治疗邪祟引起的发狂、悲泣等症状。
冯楚瞻说：天一生水，所以肾是万物的源头，也是人体的宝贝。无奈人们自己砍伐这个源头，导致根本不牢固，于是劳热发作。发热则精血枯竭，身体憔悴瘦弱，腰痛脚酸，自汗盗汗，发热咳嗽，头晕目眩，耳鸣耳聋，遗精便血，消渴淋沥，失音喉疮舌燥等症状，没有不是因此显现出来的。如果不滋水镇火，就无法控制其炎灼之势。我按语：滋水的药物，品类很多，但终究不如地黄为正统。因为地黄性温而润，色黑体沉，可以入肾滋阴，以救先天之精。至于气味稍寒，能辅助地黄去除骨蒸痞疟症状的，则有龟板、龟胶。胶比板的效果更好。辅助地黄补肌泽肤，以去除枯竭症状的，则有人乳、猪肉。肉与人乳有所不同。辅助地黄通便治疗燥症的，则有火麻仁、胡麻。胡麻比火麻仁更有益血功效。至于水亏导致眼睛不明，则需要辅助枸杞。水亏导致胎气不利、胎不下者，则有辅助冬葵子、榆白皮。水亏导致风湿不去除的，则有辅助桑寄生。水亏导致心肾不交的，则有辅助桑螵蛸、龟板。水亏导致阳痿不起的，则有辅助楮实。水亏导致筋骨不健康的，则有辅助冬青子。水亏导致精气不足的，则有辅助燕窝。水亏导致血热吐衄的，则有辅助干地黄。水亏导致阴茎坚而不软（指异常勃起或僵硬不适，此处语境似指虚损导致的机能障碍，原文“坚不软”可能有误或特指某种状态，结合上下文多为虚证，此处直译），则有辅助食盐。水亏导致虚怯不能镇静的，则有辅助磁石。水亏导致气不收及血不行的，则有辅助牛膝。水亏导致噎隔不能进食的，则有治疗用的黑铅。但黑铅为水之精华，凡是服用地黄而不能见效的，必须用黑铅镇压，使水退回北方位置，这样才对水有补益作用。然而必须是火胜水涸的情况下，才敢用它作为辅助。如果水火都衰弱，则应当辅助性温的药物以温暖肾脏，否则危害人不轻。
(Ass silkworm moth) enters the Kidney channel, supplements Mingmen Fire (Gate of Vitality Fire), and benefits Essence and Qi.
The male silkworm moth (specifically targets the Mingmen). It is the male offspring hatched from eggs laid after two silkworms have mated. Its taste is salty, and its nature is warm. Its disposition is most lustful; it mates immediately upon emerging from the cocoon. Various texts record that it can treat impotence (erectile dysfunction), increase Essence, strengthen willpower, enhance fertility, and allow for sexual intercourse without fatigue. Externally applied, it treats various sores, eliminates scars, stops hematuria, and warms the Kidneys. This is likely due to its lustful nature aiding Yang, and its salty-warm properties entering the Kidney. Therefore, in *Qianjin Fang* (Prescriptions Worth a Thousand Gold), this herb is used to treat male impotence. One pill is taken per night. (Take two sheng of silkworm moths, remove wings and feet, roast lightly over low fire until yellowish, grind into powder, form pills the size of paulownia seeds with honey, and swallow with wine.) Use Changpu (Acorus tatarinowii Rhizome) to restrain it. However, this is only indicated for cases seeking conception due to impotence. If those with Yin deficiency and hyperactive Fire use it as a means for licentious play, their Yin will be further depleted while Fire becomes more vigorous. Is it possible to avoid rapid death? Thus, ancient tonifying formulas rarely list it, fearing people might use it as a tool for self-destruction. The un-mated male is preferred. Ash from mulberry paper (silkworm excrement paper) burned can be applied to treat gan gangrene (noma). (Mix ash of mulberry paper with musk and honey, apply externally to treat gan gangrene; adding calcined alum improves efficacy.) It also treats mania, weeping, and crying caused by evil influences.
Feng Chuzhan said: "Heaven generates Water with One," thus the Kidney is the source of all things and the treasure of the human body. Alas, people often destroy this source themselves, causing the root to become unstable, leading to labor-heat (deficiency heat). Heat causes depletion of Essence and Blood, resulting in emaciation, weakness, lower back pain, soreness of the legs, spontaneous sweating, night sweats, fever, cough, dizziness, vertigo, tinnitus, deafness, spermatorrhea, hematochezia, Xiao Ke (wasting-thirst) with dribbling, loss of voice, throat sores, and dry tongue. These symptoms all manifest because of this. Without nourishing Water and suppressing Fire, one cannot control the scorching intensity of the pathogenic heat. My commentary: There are many categories of herbs that nourish Water, but none are as orthodox as Di Huang (Rehmanniae Radix). Di Huang is warm in nature and moistening in texture, dark in color and heavy in substance, allowing it to enter the Kidney to nourish Yin and rescue congenital Essence. As for herbs with slightly cold flavor and property that assist Di Huang in removing bone-steaming and abdominal masses/malaria-like syndromes, there are Gui Ban (Testudinis Carapax et Plastrum) and Gui Jiao (Colla Testudinis). The glue (Gui Jiao) is superior to the shell (Gui Ban). To assist Di Huang in tonifying muscle and moistening skin to eliminate depletion syndromes, there are Ren Ru (Human Milk) and Zhu Rou (Porcine Meat); meat differs from milk. To assist Di Huang in unblocking bowels and treating dryness syndromes, there are Huo Ma Ren (Cannabis Fructus) and Hu Ma (Sesami Fructus); Hu Ma is better at benefiting blood than Huo Ma Ren. When Water deficiency leads to unclear vision, Gou Qi Zi (Lycii Fructus) should be added. When Water deficiency leads to difficult urination or retained fetus, Dong Kui Zi (Malvae Semen) and Yu Bai Pi (Ulmus Cortex) serve as assistants. When Water deficiency fails to dispel wind-dampness, Sang Ji Sheng (Taxilli Herba) is used. When Water deficiency results in Heart-Kidney non-interaction, Sang Piao Xiao (Mantidis Ootheca) and Gui Ban are assistants. When Water deficiency causes impotence, Chu Shi (Broussonetiae Fructus) is added. When Water deficiency leads to weak sinews and bones, Dong Qing Zi (Ilicis Cornus Fructus) is an assistant. When Water deficiency results in insufficient Essence and Qi, Yan Wo (Nestor's Swiftlet Nest) is used. When Water deficiency causes blood heat with vomiting or epistaxis, Gan Di Huang (Prepared Rehmanniae Radix) is added. [Note: Text says "Jian bu ruan" - hard not soft, context implies pathological rigidity or specific dysfunction]. When Water deficiency leads to timidity and inability to calm, Ci Shi (Magnetitum) is an assistant. When Water deficiency causes Qi to fail to consolidate and Blood to fail to circulate, Niu Xi (Achyranthis Bidentatae Radix) is added. When Water deficiency causes dysphagia and inability to eat, Hei Qian (Plumbum) is used for treatment. However, Hei Qian is the essence of Water. Whenever Di Huang fails to produce a tonifying effect, Hei Qian must be used to suppress and anchor, guiding Water back to its northern position, thereby benefiting Water. Yet, this should only be employed when Fire is excessive and Water is dried up. If both Fire and Water are deficient, one should instead add warm-natured herbs to warm the Kidney; otherwise, the harm to the patient will be severe.
