按九虫论云∶蛲虫多所，变化多端，或作 、疥、痔、 ，无所不为。其汤熨针石

《养生方·导引法》云∶龙行气，低头下视，不息十二通。愈风疥、恶疮、热不能入咽
干疥但痒，搔之皮起，作干痂。此风热气深，在肌肉间故也。
湿疥起小疮，皮薄，常有水汁出，此风热气浅，在皮肤间故也。
诸阳气在表，阳气盛则表热，因运动劳役，腠理则虚而开，为风邪所客，风热相搏，留
于皮肤则生疮。初作瘭浆，黄汁出；风多则痒，热多则痛；血气乘之，则多脓血，故名热疮
凡身体发疮，皆是风热所为。然血虚者，亦伤于邪，若重触风寒，则冷气入于疮，令血
涩不行，其疮则顽，令不知痛痒，亦经久难瘥，名为冷疮。
此疽疮，是 之类也，非痈疽之疽。世云 疽，即是此也。多发于指节脚胫间
，相对生，币币作细孔，如针头，其里有虫，痒痛，搔之黄汁出，随瘥随发。皆是风邪客于
皮肤，血气之所变生。亦有因诸浅疮经久不瘥，痒痛抓搔之，或衣揩拂之，其疮则经久不瘥
，而变作疽疮者。里皆有细虫。
疥疮，有几种类型：有大疥、马疥、水疥、干疥和湿疥。多生于手足部位，甚至遍布全身。
大疥，表现为形成疮疡，有脓液流出，伴有红肿、瘙痒和疼痛。
马疥，表现为皮肤肌肉隆起不平，根部坚硬，搔抓时感觉不到疼痛。这两种病情较重。
水疥，表现为结节如小水泡，挑破后有水流出。这一种病情较轻。
干疥，仅表现为瘙痒，搔抓后皮肤起屑，形成干燥的痂皮。
湿疥，表现为小疮，皮薄，经常有汁液渗出。这些类型的疥疮中都有虫，人们往往能用针头挑出，形状像水中的虫子。这都是由于皮肤受到风邪和热气侵袭所致。
根据《九虫论》记载：蛲虫种类繁多，变化多端，有时引发瘰疬、疥疮、痔疮等病症，无所不为。其治疗所用的汤药、熨法、针刺和砭石，另有专门的方剂，补益调养和导引功法，现附在后面。
《养生方·导引法》记载：龙行气功，低头向下看，屏息十二次。可以治愈风疥、恶疮以及热邪不能入咽的症状。
干疥只是瘙痒，搔抓后皮肤起屑，形成干燥的痂皮。这是因为风热之邪较深，位于肌肉之间。
湿疥起小疮，皮薄，经常有水汁流出，这是因为风热之邪较浅，位于皮肤之间。
诸阳经之气在体表，阳气旺盛则体表发热，因运动劳役，腠理（毛孔）空虚而张开，风邪乘虚而入，风热相互搏结，停留在皮肤上则生疮。初起为小水泡，流出黄色汁液；风邪重则痒，热邪重则痛；血气受扰，则产生多量脓血，所以称为热疮。
凡是身体发生疮疡，都是风热所致。然而血虚之人，也容易受邪气伤害，如果再次触犯风寒，冷气进入疮口，导致血液涩滞不行，疮口就会变得顽固，使人不知痛痒，经久难以痊愈，称为冷疮。
这种疽疮，属于疳类疾病，不是痈疽那种疽。世人所说的疳疽，就是指的这种病。多发于手指关节和脚胫之间，对称生长，密集地生出细孔，如针头大小，里面有虫，感到瘙痒疼痛，搔抓后有黄汁流出，随愈合随即复发。这都是因为风邪客居皮肤，血气发生变化所生成。也有因为各种浅表疮疡经久不愈，因瘙痒疼痛而抓挠，或衣物摩擦，导致疮疡经久不愈，进而转变为疽疮的情况。里面也都有细小的虫子。
Jie (Scabies) presents in several types: there is Da Jie (Great Scabies), Ma Jie (Horse Scabies), Shui Jie (Water Scabies), Gan Jie (Dry Scabies), and Shi Jie (Wet Scabies). It commonly occurs on the hands and feet, and can even spread over the entire body.
Da Jie (Great Scabies) manifests as sores with pus discharge, accompanied by redness, itching, and pain.
Ma Jie (Horse Scabies) manifests as raised, uneven skin and flesh with hard roots; scratching does not elicit a sensation of pain. These two types are considered severe.
Shui Jie (Water Scabies) manifests as nodules resembling small vesicles; when broken, water flows out. This type is relatively mild.
Gan Jie (Dry Scabies) is characterized merely by itching; scratching causes the skin to flake and form dry scabs.
Shi Jie (Wet Scabies) manifests as small sores with thin skin, often exuding fluid. All these types contain parasites; people often find them using the head of an needle, and they resemble worms found in water. All of these are caused by the skin being invaded by Wind pathogenic factors and Heat qi.
According to *Jiu Chong Lun* (Treatise on Nine Parasites): Nictalopes (pinworms) are numerous and variable in their manifestations; they may cause Luoli (scrofula), Jie (scabies), hemorrhoids, and other conditions, doing everything possible. The treatments involving decoctions, moxibustion/heat application, acupuncture, and stone therapy have separate specific formulas. Tonification, nourishment, and Dao Yin (guiding and pulling) exercises are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Dao Yin Fa* (Guiding and Pulling Methods) states: Long Xing Qi (Dragon Moving Qi) involves lowering the head and looking down, holding the breath twelve times. It cures Feng Jie (Wind Scabies), malignant sores, and heat that cannot enter the throat.
Gan Jie (Dry Scabies) only itches; scratching causes the skin to rise and form dry scabs. This is because the Wind-Heat pathogenic factor is deep, located between the muscles.
Shi Jie (Wet Scabies) presents as small sores with thin skin, often exuding fluid. This is because the Wind-Heat pathogenic factor is shallow, located in the skin.
The Qi of all Yang meridians resides on the exterior. When Yang Qi is abundant, the exterior becomes hot. Due to physical exertion or labor, the Cou Li (pores/cutaneous interstices) become deficient and open, allowing Wind pathogenic factors to invade. Wind and Heat contend and remain in the skin, generating sores. Initially, they appear as small vesicles exuding yellow fluid; if Wind predominates, there is itching; if Heat predominates, there is pain. If Blood and Qi are involved, there is much pus and blood, hence it is named Re Chuang (Heat Sore).
Any sores appearing on the body are caused by Wind-Heat. However, those with Blood deficiency are also susceptible to pathogenic factors. If additionally exposed to Cold-Wind, Cold Qi enters the sore, causing Blood stasis and obstruction. The sore becomes stubborn, leading to a loss of sensation of pain and itchiness, and heals slowly over a long period, named Leng Chuang (Cold Sore).
This Ju Chuang (Ju Sore) belongs to the category of Gan diseases, not the Ju of Yong Ju (carbuncles and ulcers). What the world calls Gan Ju is precisely this condition. It frequently occurs between the finger joints and the shins, growing symmetrically, densely forming fine pores like needle heads. There are parasites inside, causing itching and pain; scratching yields yellow fluid. It heals and recurs repeatedly. All of this is generated by Wind pathogenic factors lodging in the skin and changes in Blood and Qi. There are also cases where various superficial sores fail to heal for a long time; due to scratching from itching and pain, or friction from clothing, the sore fails to heal for a long period and transforms into Ju Chuang. There are also fine parasites inside.
