《鬼遗》云∶阳疽起足趺及足下，二十日不穴死。十日可刺，发赤白脓血不多，其疮
上痒及赤黑者死。跗亦作趺，足面也。其处结毒肿痛，亦名足发背，属足厥阴肝、阳明
胃经之会，多因湿热乘虚而下注。宜服活命饮加木瓜、肉桂，牛膝及隔蒜灸之，继以十
全大补汤、托里温中汤。脓稠可治，脓清紫陷者死。 一人脚背患此，赤肿作痛，隔蒜
灸三十余壮痛止，以活命饮四剂而溃，更以托里消毒药而愈。 一人脚背患之，色黯而
不肿痛，烦躁大渴，尺脉大而涩，此精气已绝不治，后殁。 赵子固母刘氏，年六十，左
足面一疮，下连大指，上延外踝，以至 骨。每岁辄数发，发必兼旬累月。昏暮痒甚抓搔，
移时出血如泉流，呻吟痛楚，殆不可忍，夜分即渐已，明月复然。每一更药，则疮转大
而剧，百试不验，如是二十余年。淳熙甲辰仲冬之末，先生为太府丞，一夕母病大作，相
对悲泣无计。困极就睡，梦四神僧默出一室，傍有一长榻，子固亦坐，因而发叹。一僧问
其故，子固答之以实。僧云∶可服牛黄金虎丹。又一僧云∶朱砂亦可。既觉颇惊异，试
取药半粒强服之，良久大痛，举家相泣且悔。俄而下 物如铁石者数升，是夕疮但微痒
不痛而无血，数日成痂，自此遂愈。朱砂之说，竟不复试。先生因图僧像如所梦者而记
其事。金虎丹出《和剂局方》，本治中风痰涎壅塞，所用牛黄、龙脑、腻粉、金箔之类，皆
非老人所宜。今乃取奇效。意热积脏腑而发于皮肤，岁久根深，未易洗涤，故假凉剂以
攻之，不可以常伦。神僧之梦，盖孝感云。

药不瘥者。

灰研细，以纱片筛去沙土，麻油调敷。痒入轻粉；痛入麝香少许效。
治疗脚趾缝溃烂的疮疡，取鹅掌皮（即脚底脱落的厚皮），烧成炭灰但保留药性，研成细末外敷。（用桐油涂抹，效果也很好。）
《鬼遗科》说：阳疽发于足背及足底，若二十天不切开排脓就会死亡。十天左右可以针刺，如果流出赤白脓血不多，且疮口上部发痒、颜色呈赤黑者，预后不良会死亡。“跗”也写作“趺”，指足面。该部位结毒肿痛，也称为足发背，属于足厥阴肝经与足阳明胃经交汇之处，多因湿热之邪乘虚下注所致。适宜服用活命饮加木瓜、肉桂、牛膝，并配合隔蒜灸法，随后继服十全大补汤、托里温中汤。若脓液稠厚可治，若脓液清稀、疮色紫暗凹陷者则预后不良致死。有一人脚背患此病，红肿疼痛，隔蒜灸三十余壮后疼痛停止，服用四剂活命饮后化脓溃破，再用托里消毒药而痊愈。另一人脚背患病，肤色暗黑且不肿不痛，伴有烦躁和大渴，尺脉大而涩，这是精气已绝的征象，无法救治，后来去世。赵子固的母亲刘氏，六十岁，左足面生一疮，向下连至大拇指，向上延伸至外踝，直至脚踝骨。每年发作数次，每次发作必持续数十日乃至数月。黄昏时瘙痒剧烈，抓挠后出血如泉涌，呻吟痛苦，几乎难以忍受，半夜时分症状逐渐缓解，天亮后又复发。每更换一次药物，疮口反而扩大加重，尝试无数方法均无效，如此二十多年。淳熙甲辰年冬末，先生担任太府丞，一天晚上母亲病情突然加剧，相对悲伤哭泣却无计可施。极度困倦入睡，梦见四位神僧默默走出一个房间，旁边有一张长榻，赵子固也坐在上面，因而叹息。一位僧人问其原因，赵子固如实回答。僧人说：“可以服用牛黄金虎丹。”另一位僧人说：“朱砂也可以。”醒来后颇为惊异，试着取药半粒强服下去，许久后剧烈疼痛，全家相泣并后悔。不久排出如铁石般的硬物数升，当晚疮口仅微痒不痛且不出血，数日后结成痂皮，从此痊愈。关于朱砂的说法，最终没有再尝试。先生因此绘制了梦中神僧的画像并记录了此事。金虎丹出自《和剂局方》，原本治疗中风痰涎壅塞，所用牛黄、龙脑、腻粉、金箔等药，都不适合老年人服用。如今却取得奇效。推测是热毒积聚在脏腑而发于皮肤，日久根深，不易清除，所以借用凉性药物来攻伐，不能按常规常理看待。神僧之梦，大概是孝心感应的结果。

Treatment for ulcerative sores between the toes: Take goose palm skin (thick skin shed from the sole of the foot), burn it to ash while preserving its medicinal properties, grind into fine powder, and apply externally. (Applying tung oil is also effective.)
The *Gui Yi Ke* states: Yang abscesses arising on the dorsum or sole of the foot will cause death if not incised within twenty days. Incision can be performed around the tenth day. If the discharge of red-white pus and blood is scant, and the sore is itchy with a reddish-black color, the prognosis is fatal. "Fu" (dorsum of foot) is also written as "Fu". This area involves swelling and pain due to toxic accumulation, also known as "Foot Back Erysipelas" (Zu Fa Bei). It belongs to the intersection of the Foot Jueyin Liver Meridian and the Foot Yangming Stomach Meridian, often caused by damp-heat pathogens sinking downward due to deficiency. It is advisable to administer Huo Ming Yin (Life-Saving Decoction) augmented with Papaya (Mugua), Cinnamon Twig (Rougui), and Achyranthes Root (Niuxi), combined with Garlic-Separated Moxibustion. Subsequently, follow with Shi Quan Da Bu Tang (Ten Significant Tonifying Decoction) and Tuo Li Wen Zhong Tang (Support Interior and Warm Middle Decoction). Thick pus indicates a treatable condition; clear pus with purple depression indicates a fatal prognosis. One patient suffered from this on the dorsum of the foot, presenting with redness, swelling, and pain. After more than thirty moxa cones of garlic-separated moxibustion, the pain ceased. Four doses of Huo Ming Yin led to suppuration and rupture, followed by recovery using interior-supporting and detoxifying herbs. Another patient had a dark-colored lesion on the dorsum of the foot without swelling or pain, accompanied by restlessness and extreme thirst. The radial pulse was large and choppy, indicating exhaustion of essence and qi, which is untreatable; the patient subsequently died.
Zhao Zigu's mother, Lady Liu, aged sixty, had a sore on the dorsum of her left foot extending down to the big toe and up to the lateral malleolus and ankle bone. It recurred several times a year, lasting for weeks or months each time. Severe itching occurred at dusk, leading to bleeding like a spring upon scratching, with unbearable groaning pain that subsided by midnight but returned at dawn. Each change of medication exacerbated the sore. This persisted for over twenty years. In late winter of the Jiachen year of Chunxi, when Mr. Zhao served as Vice Director of the Department of the Treasury, his mother's illness suddenly worsened one night. They wept in despair. Exhausted, he fell asleep and dreamed of four divine monks emerging silently from a room. A long couch was nearby, and Zhao Zigu sat beside them, sighing. One monk asked the reason, and he answered truthfully. The monk said, "You may take Niu Huang Jin Hu Dan." Another monk added, "Cinnabar is also suitable." Upon waking, he was startled, tried taking half a pill forcibly, and after a while experienced severe pain, causing his family to weep and regret. Soon, he expelled several sheng (a unit of volume) of iron-stone-like hard matter. That night, the sore only itched slightly without pain or bleeding. It scabbed over in a few days and healed completely thereafter. The suggestion regarding cinnabar was never tested again. Mr. Zhao drew portraits of the monks as seen in the dream and recorded the event. Jin Hu Dan originates from the *He Ji Ju Fang*, originally used for stroke with phlegm-turbidity obstructing the orifices. Ingredients such as Calculus Bovis (Niu Huang), Borneolum Syntheticum (Long Nao), Calomel (Ni Fen), and Gold Leaf (Jin Bo) are generally unsuitable for the elderly. Yet, it achieved miraculous results here. It is hypothesized that heat-toxin accumulated in the zang-fu organs and manifested in the skin, becoming deeply rooted over years, difficult to cleanse. Thus, cold-natured herbs were borrowed to attack the pathogen, deviating from standard protocols. The dream of divine monks is likely attributed to filial piety moving heaven.
