申斗垣曰∶流水麻根疮，多生于足后跟下，赤烂内有肉丝缕缕如麻根相似，故
名之。是足太阳膀胱经，多血少气，又沾房事，况在跟下最难收功，必去阴染死肉
臭气，用红升药加苎麻根 灰干掺。（《启玄》）宜内服肾气丸。
《心法》曰∶土粟又名琉璃疽，生在足跟之旁，形如枣粟，亮而色黄，肿若琉璃，
此由行走崎岖之路，劳伤筋骨血脉而成。脓熟针之，脓少水多者，陀僧膏贴之。（《金鉴》）
申斗垣曰∶两足心凸肿，上生黑痘疮，其硬如疔，胫骨有碎孔髓流出，身发寒战，
惟思饮酒，此名足疔怪病。乃肝肾二经寒热毒瓦斯相合而成。（《启玄》）
《心法》曰∶冷疔生足跟，由湿寒凝结而成。形如枣粟，起紫白泡，疼痛彻骨，渐
生黑气，腐烂孔深，时流血水气秽，经久不敛者，宜神灯照之。（《金鉴》）

申斗垣说：流水麻根疮，多生长在足跟下方，患处红肿溃烂，内部有肉丝缕缕相连，形状像麻根一样，因此得名。这是足太阳膀胱经（主管体表防御的经络，多血少气）受邪，加之房事不节所致，况且位于足跟下方最难治愈，必须去除阴寒感染导致的坏死组织和臭气，使用红升药（一种含汞的腐蚀性外用丹药）加入苎麻根灰干燥后掺撒在伤口上。（《启玄》）适宜内服肾气丸（温补肾阳的经典方剂）。
《医宗金鉴·心法要诀》说：土粟又名琉璃疽，生长在足跟旁边，形状像枣或粟米，光亮且颜色发黄，肿胀如同琉璃一般，这是由于行走崎岖道路，劳损筋骨血脉而形成的。脓液成熟后用针穿刺排脓，若脓少水多者，用陀僧膏贴敷。（《金鉴》）
申斗垣说：两足心凸起肿胀，上面生出黑色痘疮，质地坚硬如疔疮，胫骨上有碎孔髓液流出，身体发冷颤抖，只想饮酒，这名叫足疔怪病。这是肝肾二经的寒热毒气相互结合而形成的。（《启玄》）
《医宗金鉴·心法要诀》说：冷疔生于足跟，由湿寒凝结而成。形状像枣或粟米，起紫白色水泡，疼痛彻骨，逐渐产生黑气，腐烂孔洞深，时常流出带秽气的血水，经久不愈合的，宜用神灯照法治疗。（《金鉴》）
铁粉散（出自《金鉴》）
生铁粉（即针砂，如果没有，可用黑铅四两，在铁勺中熔化，倾入水中冷却定型取出，再熔化再倾倒，直到用完为止，去掉水分取得纯净粉末三钱）、黄丹（用水飞法精制）、轻粉、松香（各一钱）、麝香（一分）
分别研磨成细粉，混合在一起，再次研磨均匀。将患处以葱汤清洗，洗去血水和腐臭气味，用香油调匀涂抹在患处，盖上油纸并用线扎紧。
Application Method
Ru Xiang (Frankincense), Mo Yao (Myrrh), Hai Piao Xiao (Cuttlefish Bone), Chi Shi Zhi (Red Halloysite) (equal parts each)
Grind into fine powder. Melt Huang La (Yellow Beeswax), mix evenly with the powder to form a cake, apply to the affected area and bandage; it will heal immediately.
Shen Douyuan stated: "Liushui Mageng Chuang" (Flowing Water Hemp-Root Sore) mostly occurs below the heel. The area is red, ulcerated, and contains thread-like flesh strands resembling hemp roots, hence the name. This involves the Foot-Taiyang Bladder Meridian (a meridian governing the exterior defense, characterized by abundant blood and deficient qi). It is often caused by excessive sexual activity. Furthermore, since it is located at the sole of the heel, it is difficult to cure. One must remove the foul-smelling necrotic tissue caused by yin infection. Use Hong Sheng Yao (Red Ascending Medicine, a corrosive external calx containing mercury) mixed with dried ash of Ramie Root (Zhu Ma Gen) applied as a dusting powder. Internal administration of Shen Qi Wan (Kidney Qi Pill) is advisable. (From *Qi Xuan*)
*Yi Zong Jin Jian · Xin Fa Yao Jue* states: "Tu Su" is also known as "Liuli Ju" (Glaze Carbuncle). It appears beside the heel, shaped like a jujube or millet grain, shiny and yellow in color, swelling like glaze. This results from walking on rough terrain, causing trauma to the sinews, bones, and blood vessels. Once pus matures, puncture it with a needle. If there is little pus but much fluid, apply Tuo Seng Gao (Tuo Seng Ointment). (From *Jin Jian*)
Shen Douyuan stated: "When both soles of the feet are convexly swollen, and black pock-like sores appear on top, hard as a Ding sore (carbuncle), with marrow flowing from fragmented holes in the tibia, accompanied by chills and tremors of the body, and a strong desire for alcohol, this is named 'Zu Ding Guai Bing' (Strange Disease of Foot Ding). It is formed by the combination of cold and heat toxic vapors from the Liver and Kidney meridians." (From *Qi Xuan*)
*Yi Zong Jin Jian · Xin Fa Yao Jue* states: "Leng Ding" (Cold Ding) occurring on the heel is caused by the coagulation of dampness and cold. It resembles a jujube or millet grain, presenting as purple-white blisters, with pain penetrating to the bone. Gradually, black gas appears, rotting deep holes form, and foul-smelling bloody fluid flows intermittently. For cases that do not heal over time, Shen Deng Zhao (Divine Lamp Illumination Therapy) is suitable. (From *Jin Jian*)
Tie Fen San (Iron Powder Powder) (From *Jin Jian*)
Sheng Tie Fen (Raw Iron Powder, i.e., Zhen Sha/Needle Sand; if unavailable, use 4 liang of Black Lead [He Qian], melt in an iron spoon, pour into water to cool and solidify, repeat melting and pouring until exhausted, drain water and take 3 qian of pure powder), Huang Dan (Lead Monoxide, refined by water flotation), Qing Fen (Calomel), Song Xiang (Pine Rosin) (each 1 qian), She Xiang (Musk) (1 fen)
Grind each into fine powder separately, mix together, and grind again until uniform. Wash the affected area with Cong Tang (Scallion Decoction) to remove bloody fluid and foul odor. Mix with Xiang You (Sesame Oil) and apply to the lesion. Cover with oil paper and tie securely with thread.
