葛洪云∶鬼疰是五尸之一疰，其病变动有若干种，大略使人寒热淋沥，沉沉默默，不得
知所苦，无处不恶，积年累月，渐就沉滞，以至于死。传于旁人，乃至灭门。觉如是候者，
急治獭肝一具，阴干杵末，服方寸匕，日三，未止再作。《肘后》亦云此方神良。夫獭，一
兽也，其肝能治鬼疰，此何以故哉？凡物恶人而辟处，夜出而昼伏者，皆阴类也。以阴类而
治幽隐之疾，《大易》所谓同气相求，《内经》所谓衰之以属是也。獭有五脏六腑，而独用其
肝者，肝为厥阴，其主藏魂，用之尤精良也。谚称鸱枭能疗心头气痛，亦是假阴类以疗幽隐
尔。
许学士《本事方》云∶宣和间，天庆观一法师，行考石极精严，时一妇人投状，率患人
所附。须臾召至附语云∶非我为患，别是一鬼，亦因病患命衰为祟耳。渠今已成形，在患人
肺中，为虫食其肺系，故令吐血声嘶。师掠之，此虫还有畏忌否？久而无语。再掠之，良久
云∶容某说，惟畏獭爪屑为末，酒调服之，则去矣。患家如其言而得愈。此予所目见者也。
夫獭肝、獭爪，一体也。肝极獭之阴，爪极獭之阳，肝蕴獭之精，爪利獭之用，故皆为尽妙。
《稽神录》云∶有人多得劳疾，相因传死者数人。后一女子病，生置之柜中，钉之沉于
江，冀绝传染之患。流之金山，有渔人异之，引至岸，见一女子犹然活，因取置渔舍，多得
鳗鲡鱼食之，病愈，遂为渔人之妻。又越州镜湖邵长者女十八，染瘵疾累年，刺灸无不求治，
医亦不效。有渔人赵十煮鳗羹与食，食竟，内热之病皆无矣。世人得此二说，凡遇瘵疾，即
以鳗鱼食之，率多不效。昆谓鳗鱼之性，天和则伏，风汹则动，是逐风之鳞也。若用之以疗
风尸，无不愈者。若概以之治瘵，则恐不能。风尸者，五疰之一，其证淫濯四肢，不知痛之
所在，每发昏沉，得风雪便作，渐就危笃，以至于死也。
葛洪说：鬼疰是五尸疰中的一种，这种病的变化有多种表现，大体上使人出现寒热往来、淋漓不适，神情沉默抑郁，不知道具体哪里痛苦，全身都不舒服，经过长年累月，逐渐变得身体沉重停滞，以至于死亡。还会传染给旁人，甚至导致全家灭门。如果觉察到有这样的症状，应当紧急治疗，取獭肝一副，阴干后捣成粉末，每次服用方寸匕的量，每天三次，如果病没好就再制作服用。《肘后备急方》也说这个方子神奇灵验。獭只是一种野兽，它的肝脏能治疗鬼疰，这是什么原因呢？凡是厌恶人类而避开人群，夜间出来白天潜伏的动物，都属于阴类。用阴类的动物来治疗幽隐难见的疾病，这正是《周易》所说的“同气相求”，以及《黄帝内经》所说的“衰之以属”（即利用同类属性来削弱病邪）的道理。獭具备五脏六腑，但唯独使用它的肝脏，因为肝属于厥阴经，主藏魂，所以用它尤为精良。谚语称猫头鹰能治疗心头气痛，也是借助阴类动物的特性来治疗幽隐之疾罢了。
许叔微在《本事方》中说：宣和年间，天庆观的一位法师，行刑拷问非常严厉精严。当时有一位妇人呈递状纸，声称自己被人附体。片刻之后，被附体者说话道：“不是我作祟，而是另一个鬼，也是因为病人生命衰败才成为祸害的。”它说现在已经成形，在病人的肺中，化作虫子啃食肺系，所以导致吐血、声音嘶哑。法师鞭打它，问这只虫子还有没有畏惧忌讳的东西吗？过了很久没有回答。再次鞭打它，过了许久才说：“容我说，只怕獭爪磨成的粉末，用酒调服，它就会离去。”病人家属按照这个方法做，果然痊愈了。这是我亲眼所见的事情。獭肝和獭爪，都是獭身体的一部分。肝脏极尽獭的阴柔之性，爪子极尽獭的阳刚之用；肝脏蕴藏着獭的精气，爪子利于獭的功能发挥，所以两者都极其奇妙有效。
《稽神录》记载：有人得了劳损之疾，互相传染死了数人。后来有一个女子生病，人们把她放在柜子里，钉死沉入江中，希望断绝传染的祸患。尸体漂流到金山，有个渔人觉得奇怪，把她拉到岸边，看见那个女子还活着，于是把她带回家放在渔舍里，给她吃很多鳗鲡鱼，她的病就好了，后来成了渔人的妻子。另外，越州镜湖邵家一位十八岁的女儿，染上痨瘵之疾多年，针灸求治的方法都用遍了，医生也无效。有个叫赵十的渔人煮鳗鱼羹给她吃，吃完后，内热等病症全都消失了。世人得到这两种说法，凡遇到痨瘵之疾，就用鳗鱼来吃，大多不见效。我认为鳗鱼的药性，天气平和时潜伏不动，风浪汹涌时则活动，它是逐风的鳞介类动物。如果用它来治疗风尸，没有不愈的。如果一概用它来治疗痨瘵，恐怕不行。风尸是五疰之一，其症状是四肢游走性疼痛，不知道疼痛的具体位置，每次发作时昏沉，遇到风雪天气就会发作，逐渐变得危重，以至于死亡。
Ge Hong stated: "Gui Zhu (Ghost Tethering Disease) is one of the Five Shi Zhu (Five Corpse Tethering Diseases). Its pathological changes manifest in various ways, generally causing chills and fever, dripping discomfort, a silent and depressed demeanor, with the patient unaware of specific sources of pain, feeling unwell everywhere. Over years and months, it gradually leads to stagnation and debility, eventually resulting in death. It can transmit to others, even wiping out an entire family. Upon perceiving such symptoms, one should urgently treat with one liver of a water civet (Tan), dried in the shade, pounded into powder, taken as one 'Fang Cun Bi' (a square-inch measure) per dose, three times daily. If not cured, prepare another batch. The *Zhou Hou Bei Ji Fang* (Handbook of Prescriptions for Emergencies) also states this prescription is miraculous and effective. The water civet is merely a beast, yet its liver can cure Gui Zhu; why is this? Generally, creatures that shun humans and dwell apart, emerging at night and hiding by day, belong to the Yin category. Using a Yin-category creature to treat obscure and hidden diseases aligns with what the *I Ching* (Book of Changes) calls 'same qi attracts same qi' (Tong Qi Xiang Qiu), and what the *Huang Di Nei Jing* (Yellow Emperor's Inner Canon) refers to as 'diminishing [pathogens] through their affinity' (Shuai Zhi Yi Shu). The water civet possesses all five zang and six fu organs, yet only its liver is used. The Liver belongs to Jueyin (Jueyin Meridian), governs the storage of the Hun (Ethereal Soul), making its use particularly refined. A proverb states that owls can treat chest qi pain; this too relies on using Yin-category entities to treat obscure ailments."
Xu Shuwei, in his *Ben Shi Fang* (Prescriptions from My Cabinet), wrote: "During the Xuanhe era, a Daoist priest at Tianqing Temple conducted interrogations with extreme rigor. At that time, a woman submitted a petition claiming she was possessed. Shortly after, the possessed individual spoke, saying: 'It is not I who am tormenting you, but another ghost, which acts because the patient’s vital energy is declining.' It stated that it had already taken form within the patient's lungs, transforming into a worm that eats the lung channels, thus causing hemoptysis (coughing up blood) and hoarseness. The priest whipped the entity, asking if this worm had any fears or taboos. After a long silence, upon being whipped again, it finally said: 'Let me speak; I fear only powdered water civet claws mixed with wine. If taken, I will depart.' The patient's family followed this advice, and she recovered. This is something I witnessed personally. Water civet liver and claws are parts of the same body. The liver embodies the extreme Yin nature of the civet, while the claws embody its extreme Yang utility. The liver stores the civet's essence, and the claws facilitate its function; therefore, both are extraordinarily effective."
The *Ji Shen Lu* (Records of Divine Spirits) records: "Someone suffered from Lao Ji (Consumptive Disease), which transmitted among several people, causing multiple deaths. Later, a young woman fell ill. People placed her in a cabinet, nailed it shut, and sank it in the river, hoping to cut off the source of infection. Her body drifted to Jinshan, where a fisherman found it strange, pulled her ashore, and saw she was still alive. He took her to his fishing hut and fed her many eels. Her illness healed, and she later became his wife. Additionally, the eighteen-year-old daughter of Elder Shao from Mirror Lake in Yuezhou suffered from Zhai Ji (Phthisis/Tuberculosis) for years. She sought treatment via acupuncture and moxibustion without success, and physicians were ineffective. A fisherman named Zhao Shi boiled eel soup for her to eat. After finishing it, her internal heat and other ailments vanished. Hearing these two accounts, people began feeding eels to anyone suffering from Zhai Ji, but most did not recover. I believe the nature of the eel is to remain dormant when weather is mild and active when winds are rough; it is a scaled creature that drives away wind. If used to treat Feng Shi (Wind Corpse), there is no case that does not heal. However, if used indiscriminately for Zhai Ji, it may not work. Feng Shi is one of the Five Zhu diseases. Its symptoms include wandering pain in the four limbs with unclear localization, frequent episodes of drowsiness and confusion, exacerbation during wind and snow, progressing to critical severity and death."
