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.
