卫生散、补中益气汤、十全大补汤、肾气丸、八珍汤、离宫锭子、绀珠丹（均见本书首卷）、荣卫返魂汤（见肿毒门）、八味逍遥散（见瘰疬门）、拔疔散（见疔疮门）、五香流气饮（见流注门）。
经络：足背归属于肝、胆、胃三条经脉。足大趾归属于肝、脾两条经脉。第二趾和第三趾均归属于胃经。第四趾归属于胆经。小趾归属于膀胱经。
足跗发：又名足发背。属于肝、胃二经交汇之处。由湿热之邪乘虚下注所致。初期宜用卫生散，加木瓜、槟榔、紫苏等作为引经药。体质壮实者，多由风痰热积而成。宜用牛黄金虎丹，继以十全大补汤、托里温中汤治疗。阳疽发于足背，脓液稠厚者可治，脓液清稀者难治，若出现紫色凹陷、黑血者不治。
足心痈：又名涌泉疽。初起时涌泉穴处发热是其征兆。由肾阴虚损所致。宜采用隔蒜灸法，服用活命饮，送服六味地黄丸。若有表证或里证，酌情使用发汗或攻下法。已成脓者，用十全大补汤、八味地黄丸，大剂量服用。并用多年羊角灯燃烧产生的烟熏患处。若出现黑色凹陷、不肿胀、不溃破流脓秽物、烦躁口渴、呕吐逆气、小便淋漓涩痛、疼痛彻骨、脉象微细或代脉者，为三阴败症，不治。
脱疽：生于足大趾，也生于手大趾。初起呈黄色水泡，随后如煮熟的红枣，久则黑色气蔓延，相传至五指。由饮食肥甘厚味及服用丹石热药所致。此毒积聚于骨髓，若不紫黑者生，未过关节者可治。若黑色蔓延五指，上传至足背，形体枯瘦、筋脉拘挛、疼痛且气味臭秽者死。此症若在肉上则割除，在指头上则截肢，欲使筋随骨出，以泄其毒，也不会痛苦。若等待毒筋在内断裂，虽去骨但仍溃烂者，亦不治。有人因不忍伤害遗体而致死，则更加悲伤。然而又不可独自决定治疗方案，必须与众人商议，并听取患者的意愿方可。因为病情变化驳杂不定。
截肢法：在未蔓延扩散时，用十余根头发，缠绕患指近节指骨末端，扎十余圈，逐渐收紧。随即用蟾酥饼放在原起米粒大小的患处，加艾灸至肌肉枯萎、疮口坏死为止。次日，患指全部变黑，方用利刀，寻至近节指骨缝隙中，将患指慢慢顺向取下。若流血，用金刀散止血。其余肿胀用离宫锭子涂抹。次日，若有黑色之气未尽，单用蟾酥饼研末撒布，膏药覆盖。黑色之气自退，脓液自生。用红黑二膏，按常规方法生肌收口。内服滋肾、健脾、安神、补气、养血等药物。须体内无变症，体外无混杂，十人中可治三四。若割取之后，黑色之气仍蔓延，肿痛更甚，气味臭秽无脓，口干舌硬，神志昏迷不能进食者，死。一灸有关穴位。有因修剪指甲受伤、咬伤、冻伤，女子因扎伤所致者，宜详查病因，分别治疗。此为形似而非真穴受异邪。
敦疽：只有大趾患的是脱疽，其余足趾患之则为敦疽。又名足指发。肿痛赤色，自行溃破者，由元气虚弱而湿毒壅盛所致。宜隔蒜灸，或用阳燧锭子灸，离宫锭子涂敷。服用无忧散、托里散。已溃破者，用十全大补汤、加减八味丸。灸踝骨尖数壮。若先渴后痛，或先痛后渴，色黑而不溃不痛者，此由饮食肥甘损伤脾胃，房劳损伤肾脏，精气已竭所致。不治。或按前述方法治疗，也有得生者。
甲疽：因剪指甲伤及肌肤，或指甲过长侵入肉中，致使气血受阻不通。久之腐溃而生疮泡，或胬肉包裹向上生长，指甲肿痛者。这是肌肉的疾病，不循经络，也不显现在脉诊上。大抵甲疽，只宜剔除指甲，则不用药也可痊愈。先用陈皮煎汤浸泡清洗，次用木棉旋转折叠，塞入甲内，渐渐添加。待指甲翘起，用刀剪去除。搽乌倍散。
足跟疽：生于足跟骨下，又名兔啮，像兔子咬一样。此处是督脉发源之地，肾经经过之处。若疮口不合，则跷脉之气不能发生，肾气由此泄露。只宜大补，否则成为终身疾病。如漫肿寒热，身体疲倦食少者，为脾虚下陷。用补中益气汤。傍晚发热作痛，头目不清爽者，为脾虚阴火。用补中益气汤并六味地黄丸。痰涎上升，口舌生疮者，为肾水干涸。用补中益气汤并加减地黄丸。皆以滋养化源为主。外用盐汤清洗，白术研末撒布，两日换一次。
厉痈：生于小趾，延及足旁，形状不大。
四淫：生于足上下部，形状为大痈。
这两种症状辨别外形如同脱疽，用药如同敦疽。另外足趾缝肿胀瘙痒出水者，脚心发热作痒、肌肉消瘦、口渴吐痰者，俱用六味地黄丸、补中益气汤，以滋养化源。肿胀坚硬色白不溃破者，由阴虚被外寒侵袭所致。用大防风汤。若专攻其毒，未见有生还者。足趾缝腐烂至足底，大块厚皮脱落，外表浅而内部深，疼痛难以行走者，取向东生长的桑树根白皮四两捣烂，同生白酒放入瓶内，隔水煮沸数十次取汁服用，再饮酒至醉为止。
臭田螺：生于足趾丫间，起白斑腐烂，瘙痒疼痛流水，甚至寒热，足面俱肿，由胃经湿热下注所致。用甘草汤清洗，嚼碎细茶涂敷。或用鹅掌皮烧存性敷贴。或用生桐油调敷。严重者用蟾酥饼搽涂。三日后更换珍珠散，肿胀处敷金黄散。
牛程蹇：足根肿胀，皮肉顽硬，由热脚下水见风，导致气滞血枯所致。初起用一个盆，内放砖，砖上放鸽粪，粪上盖罩篱，以脚踏在罩篱上，再从旁冲入滚水，蒸浸之，冷则更换。或用新砖烧红，用韭菜汁和醋泼洒，以脚踏之熏蒸。内脓攻注者针刺，硬皮敲裂者剪开，破流脓水者用牛角散，肉不生者用绛珠膏，皮不生者用珍珠散。
土栗：生于足跟旁边，黄肿如琉璃，无脓，由行路崎岖，跌伤筋骨所致。宜用活命饮，脓熟针刺。
冷疔：生于足跟，初起紫白色水泡，疼痛彻骨，渐至腐烂紫黑，深孔出血水，气味臭秽，经久不愈。宜用神灯照灼，铁粉散敷贴。
香港脚疮：足膝间生疮，由肾虚风湿相搏所致，久则渐增肿痛，出黄水，身热，经久不愈。宜服犀角散，洗漏芦汤，敷龙骨散。
田螺泡：生于足间，忽如火燃，随即生紫白黄水泡，胀痛，由脾经风热所致。服解毒泻脾汤，外用挑破贴膏。
肉刺：俗名鸡眼。用针拨破，用五分蟾酥溶于汤中，调一钱铅粉，涂之裹之。或用刀修净厚皮，取河豚鱼胆涂纸上贴之，二三次不再发。或以胆阴干收藏使用。
Weisheng San (Hygiene Powder), Buzhong Yiqi Tang (Decoction for Replenishing the Middle and Augmenting Qi), Shiquan Dabux Tang (Decoction for Perfect Tonification of All Deficiencies), Shenqi Wan (Kidney Qi Pill), Bazhen Tang (Eight Treasures Decoction), Ligong Dingzi (Ligong Paste), Gan Zhu Dan (Crimson Pearl Pill) (all see Volume 1), Rongwei Fanhun Tang (Decoction for Returning Ying and Wei to the Soul) (see Chapter on Swelling and Toxins), Bawei Xiaoyao San (Eight-Ingredient Free Wanderer Powder) (see Chapter on Scrofula), Badingsan (Boil-Pulling Powder) (see Chapter on Carbuncles), Wuxiang Liuqi Yin (Five-Aromatic Flowing-Qi Drink) (see Chapter on Flowing Abscesses).
Meridians: The dorsum of the foot belongs to the Liver, Gallbladder, and Stomach meridians. The great toe belongs to the Liver and Spleen meridians. The second and third toes both belong to the Stomach meridian. The fourth toe belongs to the Gallbladder meridian. The little toe belongs to the Bladder meridian.
Dorsal Foot Inflammation: Also known as "Foot Back Inflammation." It occurs at the convergence of the Liver and Stomach meridians, caused by damp-heat pathogens sinking downward due to deficiency. Initially, Weisheng San should be used, with Mugua (Papaya), Binglang (Areca Seed), Zisu (Perilla Leaf) etc., added as guiding herbs. In robust individuals, it is formed by wind-phlegm and heat accumulation. Niuhuang Jinhudans (Ox Gallstone and Tiger Bone Pills) should be used, followed by Shiquan Dabux Tang (Decoction for Perfect Tonification of All Deficiencies) and Tuoli Wenzhong Tang (Decoction for Supporting the Interior and Warming the Middle). Yang abscesses occurring on the dorsum of the foot are treatable if the pus is thick; they are difficult to treat if the pus is thin. If purple depression and black blood appear, it is untreatable.
Abscess of the Sole: Also known as Yongquan Carbuncle. Fever at the Yongquan acupoint in the early stage is its sign. It is caused by Kidney Yin deficiency. Garlic-separated moxibustion should be applied, Huoming Yin (Life-Saving Drink) taken, accompanied by Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). If exterior or interior syndromes exist, sweating or purging methods should be used appropriately. Once suppuration has occurred, large doses of Shiquan Dabux Tang (Decoction for Perfect Tonification of All Deficiencies) and Bawei Dihuang Wan (Eight-Ingredient Rehmannia Pill) should be administered. Smoke from old sheep horn lamps should be used to fumigate the area. If black depression appears without swelling, no foul pus discharges, irritability and thirst occur, vomiting and regurgitation happen, dysuria with pain persists, pain penetrates the bone, and the pulse is faint or intermittent, this indicates a failure of the Three Yin meridians and is untreatable.
Gangrene of the Toe: Occurs on the great toe of the foot and also the thumb of the hand. It begins as a yellow blister, then resembles a cooked red date. Over time, black gas spreads, potentially affecting all five toes. It is caused by excessive consumption of rich foods and hot medicinal pills containing cinnabar and sulfur. This toxin accumulates in the bone marrow. Survival is possible if there is no purple-black discoloration; treatment is feasible if the joint is not involved. If blackness spreads to all five toes and ascends to the dorsum of the foot, with emaciation, tendon retraction, severe pain, and foul odor, death ensues. If the lesion is in the flesh, it should be excised; if on the toe, amputation is required. The goal is to allow tendons to emerge with the bone to drain the toxin, causing minimal pain. If one waits for the toxic tendons to break internally, even after bone removal, ulceration will persist, rendering it untreatable. Some die because they cannot bear to harm the body, which is even more tragic. However, treatment decisions must not be made unilaterally; consultation with others and consideration of the patient's wishes are necessary, as the disease progression is variable.
Amputation Method: Before the spread, wrap the proximal interphalangeal joint of the affected toe with about ten strands of hair, tying it tightly. Place Chansu Pie (Toad Venom Cake) on the initial rice-grain-sized lesion and apply moxibustion until the tissue necroses. The next day, if the toe is entirely black, use a sharp knife to sever it at the joint line. If bleeding occurs, stop it with Jindao San (Golden Knife Powder). Apply Ligong Dingzi (Ligong Paste) to reduce swelling. If black gas remains, apply powdered Chansu and cover with ointment. The black gas will recede, and pus will form. Use Honghei Er Gao (Red and Black Ointments) to promote granulation and wound closure according to standard methods. Internally administer herbs that nourish the Kidney, strengthen the Spleen, calm the Spirit, tonify Qi, and nourish Blood. Treatment is successful in three out of ten cases if there are no internal complications or external mixed infections. If after amputation, black gas spreads further, swelling and pain worsen, there is foul odor without pus, dry mouth, stiff tongue, coma, and anorexia, death occurs. Moxibustion on relevant acupoints may help. Cases caused by nail trimming injuries, bites, frostbite, or needle pricks in women require etiology-specific treatments. These resemble true lesions but are not caused by specific acupoint pathologies.
Tun Ju (Dun Abscess): Only the great toe suffers from Gangrene; other toes suffer from Tun Ju, also called Toe Inflammation. Symptoms include swelling, pain, and redness. Spontaneous ulceration indicates deficient Yuan Qi and abundant damp-toxin. Apply garlic-separated moxibustion or Yangsui Dingzi (Yang Mirror Paste) moxibustion, and apply Ligong Dingzi (Ligong Paste). Administer Wuyou San (Carefree Powder) and Tuoli San (Interior-Supporting Powder). For ulcerated cases, use Shiquan Dabux Tang (Decoction for Perfect Tonification of All Deficiencies) and Jiaban Bawei Wan (Modified Eight-Ingredient Pill). Moxibustion on the ankle bone tip is beneficial. If thirst precedes pain, or pain precedes thirst, and the area is black, non-ulcerated, and painless, it indicates Spleen damage from rich diet and Kidney damage from sexual excess, with exhaustion of Essence and Qi. It is untreatable, though prior methods may occasionally yield survival.
Onychocryptosis (Ingrown Nail): Caused by nail trimming injuring the skin or long nails invading the flesh, obstructing Qi and Blood circulation. Prolonged obstruction leads to rot, ulceration, blister formation, or hyperplastic tissue wrapping the nail, causing swelling and pain. This is a muscle disorder, not following meridians, and not visible in pulse diagnosis. Generally, removing the nail alone can cure it without medication. Soak in Chenpi Decoction (Tangerine Peel Decoction), insert folded cotton wool under the nail gradually. When the nail lifts, cut it off with scissors. Apply Wubei San (Galla Powder).
Heel Carbuncle: Occurs below the heel bone, also known as Rabbit Bite, resembling a rabbit bite. This area is the source of the Du Meridian and passes through the Kidney Meridian. If the wound does not heal, Qiao Meridian Qi cannot generate, and Kidney Qi leaks. Major tonification is essential, otherwise it becomes a lifelong ailment. Diffuse swelling with chills and fever, fatigue, and poor appetite indicate Spleen Qi sinking; use Buzhong Yiqi Tang (Decoction for Replenishing the Middle and Augmenting Qi). Evening fever with pain and unclear head/eyes indicate Spleen deficiency with Yin Fire; use Buzhong Yiqi Tang combined with Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill). Rising phlegm-saliva and mouth ulcers indicate Kidney Water depletion; use Buzhong Yiqi Tang combined with Jiaban Dihuang Wan (Modified Rehmannia Pill). All aim to nourish the source of transformation. Externally wash with salt water and sprinkle Baizhu Powder (Atractylodes Macrocephala Powder), changing every two days.
Li Yong (Severe Carbuncle): Occurs on the little toe, extending to the side of the foot. The shape is small.
Si Yin (Four Licentious Ones): Occurs on the upper and lower parts of the foot. The shape is a large carbuncle.
Differentiate these two conditions like Gangrene; treat them like Tun Ju. Additionally, for swollen, itchy, weeping toe webs, hot itching soles, emaciation, thirst, and expectoration, use Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) and Buzhong Yiqi Tang (Decoction for Replenishing the Middle and Augmenting Qi) to nourish the source. For hard, white, non-ulcerated swelling caused by Yin deficiency attacked by external cold, use Dafangfeng Tang (Great Saposhnikovia Decoction). Attacking only the toxin rarely results in survival. For toe web rot extending to the sole, with thick skin peeling off, superficially shallow but deeply painful, boil four taels of white bark from mulberry roots growing eastward in raw white wine, drink the decoction, and follow with alcohol to intoxication.
Stinking Snail Ulcer: Occurs between toes, presenting as white blisters that rot, itch, hurt, and weep. Severe cases involve chills, fever, and foot dorsum swelling. Caused by damp-heat sinking from the Stomach Meridian. Wash with Gancao Tang (Licorice Decoction), apply crushed fine tea, or burn Goose Palm Skin to ash and apply. Alternatively, apply raw Tung Oil. Severe cases use Chansu Pie (Toad Venom Cake). After three days, change to Zhenzhu San (Pearl Powder) and apply Jinhuang San (Golden Yellow Powder) to swollen areas.
Niu Cheng Jian (Ox Journey Lameness): Heel swelling with hard skin and flesh, caused by walking barefoot in water after heating feet and exposing to wind, leading to Qi stagnation and Blood exhaustion. Initially, place a brick in a basin, pigeon dung on the brick, cover with a basket, and step on the basket. Pour boiling water alongside to steam and soak. Replace when cool. Alternatively, heat a new brick, pour leek juice and vinegar on it, and step on it to fumigate. Puncture internal abscesses, cut cracked hard skin, apply Niujiao San (Ox Horn Powder) for draining pus, Jiangzhu Gao (Crimson Pearl Ointment) for non-healing flesh, and Zhenzhu San (Pearl Powder) for non-healing skin.
Tu Li (Earth Chestnut): Occurs beside the heel, yellow and swollen like glass, without pus. Caused by rough walking damaging bones and tendons. Use Huoming Yin (Life-Saving Drink). Puncture when pus matures.
Cold Ding (Cold Thorn): Occurs on the heel. Begins as purple-white blisters, penetrating bone pain, progressing to purple-black rot, deep holes bleeding fluid, foul odor, and chronic non-healing. Use Shendeng Zhaozhao (Divine Lamp Illumination) and tie Tie Fen San (Iron Powder Powder).
Hong Kong Jiao Chuang (Athlete's Foot Ulcer): Ulcers between foot and knee, caused by Kidney deficiency and Wind-Damp interaction. Progressively increases swelling, pain, yellow discharge, fever, and chronic non-healing. Take Xijiao San (Rhinoceros Horn Powder), wash with Lulutang (Reed Catkin Decoction), apply Longgu San (Dragon Bone Powder).
Tian Luo Pao (Snail Blister): Appears suddenly like fire burning on the foot, generating purple, white, or yellow blisters with distending pain. Caused by Wind-Heat in the Spleen Meridian. Take Jiedu Xiapi Tang (Detoxifying and Draining Spleen Decoction). Externally puncture and apply plaster.
Mei Ci (Flesh Thorn): Commonly known as Corn. Break with a needle, dissolve 5 fen of Chansu (Toad Venom) in soup, mix with 1 qian of Lead Powder, apply and bandage. Alternatively, trim thick skin with a knife, apply Pufferfish Gall on paper. Repeat 2-3 times to prevent recurrence. Can also be dried and stored for use.
