臭田螺，是由足阳明胃经的湿火邪气攻注侵蚀而形成的。这种病症多发生于脚趾和脚缝之间，起初出现白斑并溃烂，先感到瘙痒后转为疼痛，破溃后流出恶臭液体，形状像田螺的壳；严重的会导致整个脚面肿胀，伴有怕冷和发热。治疗上应先使用甘草汤清洗患处，然后贴上蟾酥饼，连续三天共贴三枚，之后用珍珠散配合猪脊髓调和成膏涂抹覆盖，并在肿胀处敷上真君妙贴散，这样肿胀会逐渐消退。期间要禁止行走活动。
牛程蹇，是因为赶路匆忙，热脚下水后又受风侵袭，导致气机阻滞、血液枯竭，结成坚硬肿块，皮肤肌肉得不到荣卫之气的滋养，逐渐产生肿痛；肿块高高突起，支撑着脚难以行走，时间久了会破裂，脓水和血水混合流出。每天用温热水洗净患处，涂抹牛角散。如果有内部脓液攻注且皮肤坚韧难以刺破的情况，用大线针的针头挑破，排出脓液后症状就会缓解。如果是硬皮，敲破后用剪刀剪除；如果肌肉不长新肉，用玉红膏促进生长；如果肌肉长满但不生表皮，涂抹珍珠散，待表皮生出即可痊愈。
僵螂蛀，多生于手指关节中，不红也不热，肿胀像蝉的腹部，这是由手少阴心经的痰气凝滞所导致的。初起时不疼痛，日久才痛，疼痛久了才会腐烂，但肿胀仍不消退。用蟾酥饼膏贴敷，逐渐化为稀薄的脓液；病程近的约一年，远的可达三年，这种情况多见于体质虚弱的人。内服补益药剂，以免转变为痨瘵（消耗性疾病）。
Choutianluo (Stinky River Snail), is caused by the attack and infiltration of damp-heat fire in the Foot-Yangming Stomach Meridian. This condition mostly occurs on the toes and between the feet, initially presenting with white patches that ulcerate; it first feels itchy then painful, breaks open to discharge foul-smelling fluid, and resembles a snail shell in shape. In severe cases, the entire dorsum of the foot swells, accompanied by aversion to cold and fever. Initially, cleanse the area with Gancao Tang (Licorice Decoction), apply Chansu Bing (Toad Venom Cake) for three days (three cakes total). Subsequently, apply Zhenzhu San (Pearl Powder) mixed with pig spinal cord as an ointment cover, and fumigate the swelling with Zhenjun Miaotie San (Miraculous Lord's Adhesive Powder). The swelling will gradually subside. Avoid walking during this period.
Niuchengjian (Ox Hoof Callus), results from rushing along a journey, stepping into water with hot feet, and subsequently being exposed to wind. This leads to qi stagnation and blood depletion, forming hard nodules. The skin and muscles fail to receive nourishment from Ying and Wei (Nutritive and Defensive Qi), gradually developing swelling and pain; the swelling protrudes high, making it difficult to bear weight on the foot. Over time, it may rupture, discharging pus and fluid. Wash the area daily with warm water and apply Niujiao San (Horn Powder). If internal pus accumulates and the skin is tough and difficult to penetrate, puncture it with the head of a large linear needle; releasing the pus brings relief. For hardened skin, break it and cut it away with scissors; if flesh does not regenerate, apply Yuhong Gao (Jade Red Ointment) to promote growth; if flesh fills the wound but epidermis fails to grow, apply Zhenzhu San (Pearl Powder) until the skin regenerates and heals.
Jianglangzhu (Mantis Worm Infestation), mostly occurs in the finger joints. It is neither red nor hot, with swelling resembling the abdomen of a cicada. It arises from the stagnation of phlegm and qi in the Hand-Shaoyin Heart Meridian. Initially painless, pain develops after a long duration; prolonged pain leads to putrefaction, yet the swelling persists. Apply Chansu Bing (Toad Venom Cake) paste, which gradually transforms into thin pus. The course lasts about one year for recent cases or up to three years for distant ones; this condition is common in individuals with weak constitutions. Internal administration of tonifying agents is necessary to prevent transformation into Laozhai (Consumption Disease).
