又方 落鸦枪根，擂酒暖服，以渣敷患处。
代指者，先肿 热痛，色不黯，缘爪甲边结脓，剧者爪皆脱落，但得一物冷药汁，
渍之佳。爪者筋之余，筋赖血养，血热甚注于指端，故指肿热结聚成脓，甚则爪甲脱落。
此病类于指疽，然无蕴毒，故色不黯黑，虽久亦不杀人。内服方《圣济总录》有漏芦汤、
蓝花汤中用漏芦、蓝花、升麻、大黄、黄芩、玄参、朴硝。既无蕴毒，何为用硝黄下药？轻
病重治，能无过乎！故今不取。

〔丹〕 治手指忽肿痛，名为代指。以乌梅入醋研，浸患处立瘥。

手指关节处发生结毒，表现为红肿疼痛，又被称为病茧，又称蛇节疔，又称钉节天蛇，又称病蛇节。其治疗方法与天蛇头（指端痈疽）大同小异。
金鸡舌散：用于治疗病茧。取金鸡舌根，研磨后兑酒服用；或者研磨后兑入一半米泔水、一半醋，加热后外涂患处。
代指（指甲周围炎），起初肿胀、发热、疼痛，颜色不发暗，原因是爪甲边缘化脓，严重时指甲会全部脱落。只要用一种寒性药物的汁液浸泡患处，效果很好。指甲是筋的余气所生，筋依赖血液滋养，当血热严重并注于手指末端时，就会导致手指肿胀、发热、结聚成脓，严重时甚至导致指甲脱落。此病类似于指疽（手指部的疽证），但没有蕴积之毒，所以颜色不发黑，即使病程长久也不会致死。内服方剂中，《圣济总录》记载的漏芦汤、蓝花汤使用了漏芦、蓝花、升麻、大黄、黄芩、玄参、朴硝。既然没有蕴积之毒，为何还要使用芒硝、大黄这类泻下药？这是轻病重治，难道不会有过误吗？因此现在不采用这些方剂。
升麻汤：
升麻、甘草（各半两）
将药材细细切碎。用水二升，煎煮至一升，滤去药渣，加入半两芒硝末，搅拌均匀。温热时浸泡手指数十次，变冷后再加热，以痊愈为度。另一版本，使用栀子仁、甘草各一两。另一版本，单用甘草。另一版本，单用芒硝。另一版本，单用麻黄。均按照上述方法煎煮浸泡。
《千金方》治疗手指疼痛欲脱，用猪脂和盐煮至融化，趁热让手指在其中停留一顿饭的时间。《千金翼方》中加入干姜。另一版本，使用酱汁。另一版本，将酱和蜜煎沸，稍热敷，每天五到七次。
〔丹〕（朱丹溪）治疗手指突然肿痛，名为代指。将乌梅放入醋中研磨，浸泡患处，立即痊愈。
治疗手指肿胀，在酸浆水中加入少量盐，加热浸泡，变冷即更换。
Finger joint nodular toxin presents with redness, swelling, and pain. It is also known as "Bing Jian" (Disease Callus), "She Jie Ding" (Snake Joint Carbuncle), "Ding Jie Tian She" (Nail Joint Heavenly Snake), or "Bing She Jie" (Disease Snake Joint). Its treatment method is largely similar to that of "Tian She Tou" (Tip of the Finger Carbuncle).
Jinji She San (Golden Chicken Tongue Powder): Treats Bing Jian. Grind the root of Jinji She (likely *Lobelia chinensis* or similar local herb) and take it mixed with wine. Alternatively, grind it and mix with half rice water and half vinegar, warm it, and apply externally to the affected area.
Another prescription: Grind the root of Luoya Qiang (likely *Paederia scandens* or similar local herb), mix with wine for warm internal consumption, and apply the dregs to the affected area.
Dai Zhi (Paronychia/Ingrown Nail Infection) initially presents with swelling, heat, and pain, but the color does not turn dark. This occurs because pus forms at the edge of the nail; in severe cases, the entire nail may fall off. Soaking the affected part in the juice of a single cold-natured medicinal plant yields good results. The nail is considered the surplus of sinews (tendons/ligaments), which rely on blood for nourishment. When blood heat is severe and flows to the finger tips, it causes swelling, heat, and accumulation leading to pus formation in the fingers; in extreme cases, the nails fall off. This condition resembles Zhi Ju (Digital Carbuncle/Gangrene), but lacks accumulated toxic heat, hence the color does not turn black, and even if prolonged, it is not fatal. Internal prescriptions in *Shengji Zonglu* include Lou Lu Tang (Leuzea Decoction) and Lan Hua Tang (Blue Flower Decoction), which use Lou Lu (Radix Euphorbiae Humifusae), Lan Hua (likely *Centranthera chinensis* or similar), Sheng Ma (Rhizoma Cimicifugae), Da Huang (Radix et Rhizoma Rhei), Huang Qin (Radix Scutellariae), Xuan Shen (Radix Scrophulariae), and Po Xiao (Natrii Sulfas). Since there is no accumulated toxicity, why use purgatives like Po Xiao and Da Huang? Treating a mild disease with heavy measures risks error. Therefore, these are not adopted currently.
Sheng Ma Tang (Cimicifuga Decoction):
Sheng Ma (Rhizoma Cimicifugae), Gan Cao (Radix Glycyrrhizae) (each 0.5 liang).
Finely chop the herbs. Add two sheng of water, decoct until one sheng remains, strain, then add 0.5 liang of powdered Mang Xiao (Natrii Sulfas), and stir well. Warm-soak the fingers dozens of times; re-warm when cool, continuing until healed. Another version uses Zhi Zi Ren (Semen Gossypii Herbacei Preparatum - note: usually Zhi Zi is Gardenia, here likely typo for Zhi Zi or specific variety) and Gan Cao (1 liang each). Another version uses only Gan Cao. Another uses only Mang Xiao. Another uses only Ma Huang (Herba Ephedrae). All are prepared by decoction and soaking as described above.
*Qianjin Fang* treats painful fingers threatening to detach by boiling pig fat with salt until melted, keeping the finger immersed while hot for the duration of one meal. *Qianjin Yi Fang* adds Gan Jiang (Rhizoma Zingiberis). Another version uses Jiang Zhi (Sauce Juice). Another version boils Jiang (Soy Sauce/Paste) with Mi (Honey), applies slightly warm compresses, five to seven times daily.
[Dan] (Zhu Danxi) treats sudden swelling and pain of the fingers, named Dai Zhi. Grind Wu Mei (Fructus Mume) in vinegar and soak the affected area for immediate cure.
To treat finger swelling, add a little salt to Suan Jiang Shui (Sour Fermented Rice Water), heat and soak; change when cool.
