【方歌】蜣螂蛀由痰气凝，指节坚肿蝉肚形，初起不疼久方痛，
溃久脓清痨病成。
【注】此证多生于体虚人手指骨节，由湿痰、寒气凝滞而成。
初起不红不热不痛，渐次肿坚，形如蝉肚，屈伸艰难，
日久方知木痛。初肿时，宜先服六君子汤益气、除湿、
化痰；外以离宫锭姜汁磨敷，或兼阳燧锭于坚痛处灸之
自消。若失于调治，肿处渐渐腐烂，肿如溃水，淋沥不
已，肿仍不消。然在骨节之处，溃久大泄气血，每成疮
痨之证。宜豫服人参养荣汤补之，外贴蟾酥饼子，陀僧
膏盖之。遇壮年人，如法治之可愈；若年老及虚嬴之人
，不能收功。
方剂：六君子汤（香砂六君子汤减去藿香、砂仁。见肿疡门）
离宫锭（见肿疡门）
阳燧锭（见首卷烙法）
人参养荣汤、蛇僧膏（见溃疡门）

【方歌】瘑疡每发指掌中，两手对生茱萸形，风湿痒痛津汁水，
时好时发久生虫。
【注】此证生于指掌之中，形如茱萸，两手相对而生。亦有成
攒者，起黄白脓疱，痒痛无时，破津黄汁水，时好时发
，极其疲顽，由风湿客于肤腠而成，以润肌膏擦之。若
日久不愈，其痒倍增，内必生虫，治以杀虫为主，用藜
芦膏擦之甚效。忌动风、鸡鹅、鱼腥等物。
方剂：藜芦膏
组成：藜芦 苦参（各一两）
猪脂油八两，将二味炸枯，滤去渣；入松香一两溶
化开，离火，再加枯矾末、雄黄末各一两。搅匀，候温
涂之，以痊为度。

【方歌】蜣螂蛀这一病症由痰湿与气机郁结凝滞所致，表现为指节坚硬肿胀，形状像蝉的腹部。初期不疼痛，日久才出现疼痛，溃破后脓液清稀，最终形成类似痨病的慢性消耗性疮疡。
【注】此证多发生于体质虚弱者的手指骨节处，是由湿痰和寒气凝滞而形成的。
初起时局部不红、不热、不痛，逐渐变得肿胀坚硬，形状如同蝉肚，手指屈伸困难，
时间久了才会感到麻木疼痛。在初次肿胀时，适宜先服用六君子汤（Six君子 Decoction）以益气、除湿、化痰；外用离宫锭（Ligong Ding），用姜汁磨开后敷贴，或者配合阳燧锭（Yangsui Ding）在坚硬疼痛处进行灸治，肿块自然消散。如果延误调理治疗，肿胀部位逐渐腐烂，流出如溃烂般的清水，淋漓不止，肿胀依然不消退。然而病变位于骨节之处，溃破日久会大量耗伤气血，往往演变成疮痨之证。此时宜预先服用人参养荣汤（Renshen Yangrong Tang）进行补益，外贴蟾酥饼（Chansu Bing），再用陀僧膏（Tuoseng Gao）覆盖。若是青壮年患者，按此法治愈有望；若是年老体弱或极度消瘦之人，则难以取得疗效。

【方歌】瘑疮（Qie Chuang）每发于指掌之中，两手相对而生，形状像茱萸果实。伴有风湿引起的瘙痒疼痛及渗出黄水，病情时好时坏，日久生虫。
【注】此证生于手指和手掌之间，形状像茱萸，两手对称生长。也有聚集成簇的情况，起初出现黄白色的脓疱，瘙痒疼痛无定时，破溃后流出黄色汁水，病情反复发作，极其顽固难愈，这是由于风湿邪气客居于皮肤腠理之间所致，可用润肌膏（Runji Gao）擦拭治疗。如果日久不愈，瘙痒加倍剧烈，体内必然生虫，治疗应以杀虫为主，使用藜芦膏（Lilu Gao）擦拭效果显著。忌食动风食物以及鸡肉、鹅肉、鱼类腥膻之物。
方剂：藜芦膏
组成：藜芦（Lilu）、苦参（Kushen）各一两。
取猪脂油八两，将上述两味药炸至枯焦，滤去药渣；加入松香一两使其熔化，离火后，再加入枯矾末、雄黄末各一两。搅拌均匀，待温度适宜时涂抹患处，以痊愈为度。
【方歌】藜芦膏中苦参功效良，猪油炸滤后加入松香，再加枯矾与雄黄搅拌均匀，
用于杀虫止痒，涂抹治疗瘑疮。

[Prescription Verse] Qianglang Zhu (Beetle-bitten Fungus) arises from the coagulation of phlegm and qi stagnation, presenting as hard swelling of the finger joints with a shape resembling a cicada's abdomen. Initially painless, it becomes painful after a long duration; upon ulceration, the pus is clear, eventually forming a chronic wasting condition akin to tuberculosis.
[Note] This condition mostly occurs in the finger joints of individuals with weak constitutions, resulting from the stagnation of damp-phlegm and cold qi.
Initially, there is no redness, heat, or pain; gradually, it swells and hardens, taking on a shape like a cicada's abdomen, making flexion and extension difficult.
Only after a long time does one feel numbness and pain. At the initial stage of swelling, it is appropriate to first administer Liujunzi Tang (Six Gentlemen Decoction) to tonify qi, resolve dampness, and transform phlegm; externally apply Ligong Ding (Palace Separation Paste), ground with ginger juice for application, or alternatively use Yangsui Ding (Sun-warming Paste) for moxibustion on the hard and painful areas, which will naturally dissipate. If treatment is neglected, the swollen area gradually rots, oozing clear fluid continuously, while the swelling persists. However, since the lesion is located at the joint, prolonged ulceration severely depletes qi and blood, often evolving into a condition known as "chuang lao" (fungal tubercle). At this stage, it is advisable to preemptively take Renshen Yangrong Tang (Ginseng Nourishing Harmony Decoction) for supplementation, externally apply Chansu Bing (Toad Venom Cake), and cover it with Tuoseng Gao (Lead Oxide Plaster). For young and robust individuals, cure is possible following this method; however, for the elderly or those who are emaciated and weak, therapeutic success is unlikely.
Prescriptions: Liujunzi Tang (Xiangsha Liujunzi Tang minus Huoxiang and Sharen. See Chapter on Swollen Ulcers)
Ligong Ding (See Chapter on Swollen Ulcers)
Yangsui Ding (See First Volume, Moxa Cauterization Method)
Renshen Yangrong Tang, Tuoseng Gao (See Chapter on Ulcerated Sores)

[Prescription Verse] Qie Chuang (Scaly Itch) frequently erupts in the fingers and palms, appearing symmetrically on both hands with a shape resembling cornel fruit. It involves wind-dampness causing itching and pain, with serous discharge, recurring intermittently, and eventually leading to parasitic infestation over time.
[Note] This condition arises between the fingers and palms, shaped like cornel fruit, growing symmetrically on both hands. In some cases, they cluster together, starting as yellowish-white pustules. Itching and pain occur without fixed timing, and upon rupture, yellow fluid exudes. The condition recurs repeatedly and is extremely stubborn and persistent, caused by wind-damp pathogens lodging in the skin and interstices. It should be treated by rubbing Runji Gao (Moisturizing Muscle Ointment). If it persists for a long time without healing, the itching intensifies significantly, implying internal parasitic generation. Treatment should focus primarily on eliminating parasites, using Lilu Gao (Veratrum Ointment) for rubbing, which is highly effective. Avoid foods that stir wind, as well as chicken, goose, and fishy seafood.
Prescription: Lilu Gao
Composition: Lilu (Veratri Radix) and Kushen (Sophorae Flavescentis Radix), each 1 liang.
Take 8 liang of lard, fry the two herbs until charred, filter out the dregs; add 1 liang of pine rosin and melt it, remove from heat, then add 1 liang each of calcined alum powder and realgar powder. Stir evenly, wait until warm, and apply to the affected area until healed.
[Prescription Verse] In Lilu Gao, Kushen works excellently, fried in lard and filtered before adding pine rosin, followed by stirring in calcined alum and realgar,
to eliminate parasites and relieve itching when applied to Qie Chuang.
