足跟是督脉发源的地方，也是肾经经过的部位。如果饮食没有节制，起居作息不当，导致足三阳经亏损，就会形成疮疡。
如果是阴火引起的，用前面的汤剂配合六味丸。如果痰涎上涌，口舌生疮，属于肾水干涸所致，用前面的汤剂配合加减八味丸。凡是这些情况都应当滋养其化源（根本），如果只治疗外部症状就错了。俗话所说的“兔啮疮”，大概是因为猎人被兔子咬伤足跟，时间久了伤口不愈合，气血耗竭所致。
【医案实录】
大尹陈汝邻，双腿酸软无力，有时发红有时发白，足跟肿胀，有时疼痛有时瘙痒，之后疼痛加剧，皮肤感觉像没有皮一样，或者像皱纹裂开，从下午到夜晚，出现胀痛和发热。我用补中益气汤加入八味丸的药料，通过补益肝肾而治愈。
一个男子足跟疼痛，伴有发热、口渴、身体疲倦，小便像淋证一样不畅，误用了败毒散，导致头痛、恶寒、想呕吐、不想吃东西、吐痰、咳嗽。这是足三阴经亏损，而且药物又进一步损伤了正气。我使用十全大补汤、加减八味丸，各服用五十多剂后痊愈。
一个男子平时不注意起居养生，内有虚热引致饮水，感到口渴、身体疲倦，两脚发热，后来足跟疼痛。有人给他用清热除湿的药剂，反而加重了傍晚时的发热，这是因为足三阴经亏损。早晨服用十全大补汤，晚上服用加减八味丸，外用当归膏敷贴，两个多月后痊愈。
那些服用消毒类药物而死的人，数不胜数。
另一个男子也患此病，服用消毒散，涂抹追蚀药（腐蚀性药物），导致虚症层层叠出，形体消瘦如骨立，自己断定必死无疑。我使用十全大补汤，兼加山茱萸、山药，两个多月后痊愈。
一个生活优裕、喜食肥甘厚味的人，双脚发热且口渴，左尺脉数而无力。我说：这是足三阴经亏损，要预防疽病的发生。他不相信，反而继续服用……（原文此处似有缺漏，指代前文提到的错误疗法或他药）。我使用补中益气汤、六味地黄丸，服了一百多剂。而那些不相信我的建议，患上疽病以致无法挽救的人太多了！
一个妇人劳累后足跟发热疼痛，我认为这是三阴虚损，使用八珍汤而痊愈。后来全身搔痒，误服了祛风药，出现发热、抽搐，肝脉洪大而数。这是肝血虚火盛而生风，我用天竺黄、胆星制成丸药，用四物汤、麦门冬、五味子、黄芩、黄连、炙甘草、山栀、柴胡煎汤送下丸药而痊愈。
一个妇人两脚发热，两足跟疼痛，傍晚时发热更严重。我认为这是肝肾血虚，使用加味逍遥散、六味地黄丸，五十多剂后，各种症状全部痊愈。
一个妇人原本血虚，因为过度劳累，两脚发热、傍晚发热，月经过期不来。有人给她用四物汤、黄连，导致饮食减少、思虑减退，胸膈痞闷、吐痰。又用二陈汤、枳实、黄连，导致大便不成形，吐痰无度，足跟疼痛。我说：足热、傍晚发热、月经过期，乃是肝脾血虚。胸膈痞闷、吐痰、饮食减少，是脾胃虚弱。因为胃是五脏的根本，胃气一虚，各种病症都会到来。先用补中益气汤加白茯苓、半夏，使脾胃逐渐强健。然后佐以六味地黄丸，以补益脾肾，不到两个月就痊愈了。
一个妇人月经不调，发热、傍晚发热，胸膈不利，饮食减少。服用清热宽中消导的药物，前面的症状更加严重，更兼肢体酸痛；服用除湿化痰等药，月经两个月来一次；服用通经降火等药剂，两足跟趾疼痛，热度像被火烤一样。我认为这是足三阴经亏损，使用补中益气汤、六味地黄丸，两个月后各种症状逐渐消退；又用前面的汤剂配合八珍散，两个月后康复。
一个妇人足跟肿胀，双腿酸软无力，有时发红有时发白，有时瘙痒有时疼痛，之后感觉像没有皮一样，或者像皱纹裂开，从下午到夜晚，出现胀痛和发热。这是足三阴经亏损，使用加减八味丸，以及逍遥散加熟地黄、川芎，一百多剂后痊愈。

The heel is the origin of the Du Mai (Governor Vessel) and the pathway of the Kidney Meridian. If diet is irregular or daily routine is improper, leading to deficiency of the Foot Triple-Yang Meridians, sores will form.
If it is caused by Yin Fire (deficiency fire), use the aforementioned decoction combined with Liuwei Wan (Six-Ingredient Pill with Rehmannia). If phlegm-fluids rise causing mouth and tongue ulcers, it belongs to dryness and depletion of Kidney Water; use the aforementioned decoction combined with Jiawei Bawei Wan (Modified Eight-Ingredient Pill). In all such cases, one must nourish the source of transformation (the root cause); treating only the external symptoms would be a mistake. The common term "Rabbit Bite Sore" likely refers to a wound on the heel bitten by a rabbit that fails to heal over time due to exhaustion of Qi and Blood.
[Case Records]
Chen Rulin, Da Yin (a minor official), suffered from soreness and weakness in both legs, which appeared red or white at times. His heels were swollen, sometimes painful, sometimes itchy, followed by intensified pain. The skin felt as if absent or wrinkled and cracked. From late afternoon into the night, he experienced distending pain and heat. I used Bushi Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) added with ingredients of Bawei Wan (Eight-Ingredient Pill), tonifying the Liver and Kidneys until he recovered.
A man suffered from heel pain, accompanied by heat, thirst, fatigue, and dysuria resembling strangury. He mistakenly used Baidu San (Detoxification Powder), resulting in headache, aversion to cold, nausea, anorexia, expectoration, and coughing. This was due to deficiency of the Foot Three-Yin Meridians, further injured by medication. I administered Shiquan Dabu Tang (Ten-Agent Great Tonifying Decoction) and Jiawei Bawei Wan (Modified Eight-Ingredient Pill), each taken for over fifty doses, until he recovered.
Another man, who neglected his daily routine, suffered from internal heat inducing thirst,渴 (thirst), fatigue, and heat in both feet, later developing heel pain. Someone prescribed herbs to clear heat and drain dampness, which exacerbated his evening fever. This was due to deficiency of the Foot Three-Yin Meridians. I prescribed Shiquan Dabu Tang in the morning and Jiawei Bawei Wan in the evening, with external application of Danggui Gao (Angelica Ointment). He recovered after more than two months.
Those who died from taking disinfectant-type drugs are too numerous to list.
Another man suffered from this condition, taking Xiaodu San (Disinfectant Powder) and applying corrosive medicines (Zhuisi Yao). This led to a succession of deficiency symptoms, leaving him emaciated to the point of being skeletal. Believing himself doomed to die, I treated him with Shiquan Dabu Tang, supplemented with Shanzhuyu (Cornus Fruit) and Shanyao (Dioscorea Rhizome). He recovered after more than two months.
A person accustomed to rich food and drink suffered from heat and thirst in both feet, with a rapid and weak pulse at the left Chi position. I stated: "This is deficiency of the Foot Three-Yin Meridians; beware of Ju (deep abscesses)." He did not believe me and instead took... [text missing/implied incorrect treatment]. I used Bushi Yiqi Tang and Liusheng Dihuang Wan (Six-Ingredient Rehmannia Pill) for over a hundred doses. Many others who did not heed my advice developed Ju and could not be saved!
A woman suffered from heat and pain in her heels upon exertion. I diagnosed it as deficiency of the Three Yin, and she recovered using Bazhen Tang (Eight-Treasure Decoction). Later, she experienced generalized pruritus. Mistakenly taking wind-dispelling herbs, she developed fever and convulsions, with a surging and rapid Liver pulse. This was wind generated by Liver Blood deficiency and hyperactive fire. I prepared pills made of Tianzhu Huang (Bambusa Textilis Tuber) and Dansheng (Arisaema Cum Bile), administering them with a decoction of Siwu Tang (Four-Substance Decoction), Maimendong (Ophiopogon Root), Wuweizi (Schisandra Fruit), Huangqin (Scutellaria Root), Huanglian (Coptis Rhizome), Zhigancao (Prepared Licorice Root), Shanzhi (Gardenia Fruit), and Chaihu (Bupleurum Root). She recovered.
A woman suffered from heat in both feet and pain in both heels, with severe heat in the late afternoon. I diagnosed it as Liver and Kidney Blood deficiency. Using Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder) and Liusheng Dihuang Wan for over fifty doses, all symptoms resolved.
A woman with inherent Blood deficiency suffered from heat in both feet and evening fever due to excessive labor, along with delayed menstruation. Someone prescribed Siwu Tang and Huanglian (Coptis Rhizome), leading to poor appetite, chest fullness, and expectoration. Subsequently, Erchen Tang (Two-Aged Phlegm Resolving Decoction), Zhishi (Immature Bitter Orange), and Huanglian were used, resulting in loose stools, excessive expectoration, and heel pain. I said: "Foot heat, evening fever, and delayed menstruation indicate Liver and Spleen Blood deficiency. Chest fullness, expectoration, and poor appetite indicate Spleen and Stomach deficiency. The Stomach is the foundation of the Five Zang Organs; once Stomach Qi is deficient, various symptoms arise." I first used Bushi Yiqi Tang added with Baifuling (Poria) and Banxia (Pinellia Tuber) to strengthen the Spleen and Stomach. Then I supplemented with Liusheng Dihuang Wan to tonify the Spleen and Kidney. She recovered in less than two months.
A woman with irregular menstruation suffered from fever, evening fever, chest diaphragm discomfort, and poor appetite. After taking herbs to clear heat, broaden the middle, and promote digestion, her previous symptoms worsened, accompanied by limb soreness and pain. Taking herbs to drain dampness and resolve phlegm resulted in menstruation occurring only once every two months. Taking agents to unblock menstruation and descend fire caused pain in the heels and toes, with heat feeling like burning. I diagnosed this as deficiency of the Foot Three-Yin Meridians. Using Bushi Yiqi Tang and Liusheng Dihuang Wan, her symptoms gradually receded over two months. Then, using the aforementioned decoction combined with Bazhen San (Eight-Treasure Powder), she recovered after another two months.
A woman suffered from swelling of the heels, soreness and weakness in both legs, appearing red or white at times, with itching or pain. Later, the skin felt as if absent or wrinkled and cracked, with distending pain and heat from late afternoon into the night. This was due to deficiency of the Foot Three-Yin Meridians. Using Jiawei Bawei Wan (Modified Eight-Ingredient Pill) and Xiaoyao San (Free and Easy Wanderer Powder) added with Shudi (Prepared Rehmannia Root) and Chuanxiong (Ligusticum Rhizome) for over a hundred doses, she recovered.
