方剂：加味太乙膏（见溃疡门）
【方歌】田螺疱生于足底，由体内湿气与外部寒邪蒸腾郁结而成。症状表现为如豆粒大小的黄色水疱，伴有闷胀感、质地坚硬，破溃后流出臭水，导致皮肤水肿腐烂并疼痛。
【注】此病症多发生于足底，手掌处罕见。病因多为脾经湿热下注，加之外部寒邪闭塞；或因身体发热时涉水，湿冷之气蒸腾郁结所致。初起时形状如豆粒，为黄色水疱，感觉闷胀，质地坚硬且疼痛，难以着地行走。若连续长出数个水疱，因皮厚难以自行破裂，蔓延三至五个成片，会导致皮肤湿烂；严重时足背也会肿胀，出现忽冷忽热的症状。治疗法则适宜用苦参、石菖蒲、野艾煎汤热洗，随后用线针将水疱挑破，放出臭水，外贴加味太乙膏。接着剪去疱皮，宜用石膏、轻粉等份研成粉末撒在患处，仍以加味太乙膏覆盖贴敷，内服解毒泻脾汤。更有常年不愈者，属于下部湿寒，常服金匮肾气丸（Jinkui Shenqi Wan, Kidney Qi Pill from the Golden Cabinet）效果显著。

【方歌】肉刺证由缠脚引起，或是穿着窄鞋长途行走所致。行走艰难且疼痛剧烈，用玉簪根捣碎后贴涂有效。
【注】此证生于脚趾，形状像鸡眼，故俗名鸡眼。根部深陷肉里，顶部凸起变硬，疼痛导致无法行走。或因缠脚，或穿窄鞋远行，皆可引发此病。治疗法则适宜贴敷加味太乙膏以滋润患处，或用紫玉簪花根捣烂贴涂，上面覆盖油纸。另外，用地骨皮和红花等份研细，用香油调敷也有效。
[Prescription Verse] Tianluo Pao (Snail Blister) arises on the sole of the foot, formed by the steaming and stagnation of internal dampness and external cold. The symptoms present as yellow blisters the size of a bean, accompanied by a stifling sensation, hardness, and upon rupture, foul-smelling fluid that causes edema, rotting of the skin, and pain.
[Commentary] This condition mostly occurs on the soles of the feet, rarely on the palms. It is caused by damp-heat pouring downward from the Spleen Meridian, combined with external cold blocking the pores; or it results from wading in water while the body is hot, where damp-cold qi steams and stagnates. Initially, it appears like a bean-sized yellow blister, feeling stifled and swollen, hard and painful, making it difficult to walk on the ground. If several blisters grow together, their thick skin makes self-rupture difficult; spreading into patches of three to five, they become wet and rotten. In severe cases, the dorsum of the foot swells, and there are alternating chills and fever. The treatment method should involve boiling Kushen (Sophorae Flavescentis Radix), Changpu (Acori Tatarinowii Rhizoma), and Yeai (Artemisiae Argyi Herba) for hot washing. Subsequently, use a thread needle to puncture the blisters to drain the foul fluid, then apply Jiawei Taiyi Gao (Modified Taiyi Plaster). After trimming off the blister skin, sprinkle a powder made of equal parts Shigao (Gypsum Fibrosum) and Qingfen (Calamina) onto the lesion, and cover it again with Jiawei Taiyi Gao. Internally, administer Jiedu Xiapi Tang (Detoxifying and Spleen-Draining Decoction). For those who do not heal for years, it is due to damp-cold in the lower part of the body; regularly taking Jin Kui Shen Qi Wan (Kidney Qi Pill from the Golden Cabinet) is very effective.
Formula: Jiedu Xiapi Tang (Detoxifying and Spleen-Draining Decoction)
Ingredients: Shigao (calcined Gypsum Fibrosum), Niubangzi (fried and ground Arctii Fructus), Fangfeng (Saposhnikoviae Radix), Huangqin (Scutellariae Radix), Cangzhu (fried Atractylodis Rhizoma), Gancao (raw Glycyrrhizae Radix et Rhizoma), Mutong (Akebiae Caulis), Shanzhi (raw and ground Gardeniae Fructus).
Preparation: Use two zhong (approx. 400 ml) of water and twenty roots of Dengxincao (Junci Medullae), decoct until reduced to eight fen (approx. 160 ml), and take orally.
[Prescription Verse] Jiedu Xiapi Tang contains Huangqin and Niubangzi, along with Fangfeng, Shigao, Gancao, Cangzhu, Mutong, and Shanzhi. When Tianluo Pao arises, it is suitable to decoct and take this prescription, which clears heat, disperses wind, and removes dampness.
Another Formula: Jiawei Taiyi Gao (Modified Taiyi Plaster) (See Ulcer Section)
Jin Kui Shen Qi Wan (i.e., Guifu Dihuang Wan plus Cheqianzi and Nixi, each one liang. See Facial Malar Ulcer section)
[Prescription Verse] Roci (Corn/Callus) arises from foot-binding or walking long distances in narrow shoes. Walking is difficult and pain is severe; applying crushed Yuzan Gen (Tricyrtis Rhizome) externally is effective.
[Commentary] This condition occurs on the toes, resembling a corn, hence commonly known as "chicken eye." The root sinks deep into the flesh, while the top protrudes hard, causing pain that prevents walking. It can be caused by foot-binding or walking long distances in narrow shoes. The treatment method should involve applying Jiawei Taiyi Gao to moisten the area, or using crushed Ziyuzizan Huagen (Purple Tricyrtis Flower Root) applied externally, covered with oiled paper. Alternatively, grinding Gudupi (Phellodendri Cortex) and Honghua (Carthami Flos) in equal parts and mixing them with sesame oil for application is also effective.
