王肯堂曰∶疥有五种∶一曰大疥, 赤痒痛,作痒有脓。二曰马疥,隐起带根,
(搔不知痛。)三曰水疥,( 含浆,摘破出水。)四曰干疥,(痒而搔之,皮起干痂。)五曰湿疥,(薄皮小疮,
常常淫汁者是也。)宜分治之。(《准绳》)
陈实功曰∶疥疮皆因脾经湿热,肺经风毒,客于肌肤,毒之浅者为疥;毒之深
者成癣;脾受 湿之热,发为脓窠烂疮、疥癣。皆有小虫,染人最易。切忌热汤浸洗,
图片刻之快畅,殊不知热毒攻里,虫愈深入,虽有良方,何能刻日奏效,患者戒之。
兼忌一切发物海鲜。(《正宗》)
生疥疮不可在浴室内去浴,必须以药汤在自家屋内浴之。至于药裹纸内,或在
火炉,或在被内熏治,切不可为训,恐引毒入脏腑害人,慎之,慎之。(《石室秘录》)
蒋示吉曰∶疥有干疥、湿疥、虫疥、砂疥、紫疥之称,小如疹子,干而且痒者是。
此乃风热虫也。宜内服疥灵丹,外搽三黄丹自愈。(《说约》)
《心法》曰∶疥有干、湿、虫、沙、脓五种。如肺经燥热盛则生干疥,瘙痒皮枯
而起白屑;脾经湿盛则生湿疥, 肿作痛,破津黄水,甚流黑汁;肝经风盛则生虫疥,
瘙痒彻骨,挠不知痛;心血凝滞则生沙疥,
形如细砂, 赤痒痛,抓之有水;肾经湿热则生脓窠疥,形如豆粒,便利作痒,脓
清淡白。或脾经湿盛亦生脓窠疥,但顶含稠脓,痒痛相兼为异。而体虚之人亦生,以
便秘为实,便利为虚;亦有虚而便燥者,如气秘则便燥,血分枯燥则便涩。又在疮之形色,脉之有无力辨之。
Wang Kentang stated: There are five types of scabies (Jie): The first is called Da Jie (Large Scabies), characterized by redness, itching, and pain, with pus exuding upon scratching. The second is Ma Jie (Horse Scabies), presenting as隐起的 lesions with roots, (where scratching does not cause pain). The third is Shui Jie (Water Scabies), (containing serous fluid that flows out when broken). The fourth is Gan Jie (Dry Scabies), (characterized by itching where scratching causes the skin to flake and form dry crusts). The fifth is Shi Jie (Damp Scabies), (thin-skinned small sores that frequently ooze fluid). These should be treated separately. (From *Yixue Zhunsheng*)
Chen Shigong stated: Scabies arises from damp-heat in the Spleen Meridian and wind-toxin in the Lung Meridian, lodging in the skin and muscles. When the toxin is superficial, it manifests as scabies; when deep, it becomes tinea (Xuan). If the Spleen is affected by damp-heat, it may develop into pustular ulcers or scabies/tinea. All these conditions involve tiny insects and are highly contagious. One must strictly avoid soaking in hot water for washing; although this may provide temporary relief, it inadvertently drives heat-toxin inward, causing the insects to burrow deeper. Even with excellent prescriptions, how can quick results be expected? Patients must beware. Additionally, one must avoid all "fa wu" (stimulating foods) and seafood. (From *Waike Zhengzong*)
When suffering from scabies, one should not bathe in public bathhouses but must use medicinal decoctions to bathe at home. Methods such as wrapping medicine in paper and placing it near a stove, or fumigating under blankets, should never be followed, as this risks driving the toxin into the zang-fu organs and harming the body. Be extremely cautious, most cautious. (From *Shishi Milu*)
Jiang Shiji stated: Scabies is referred to as Gan Jie (Dry Scabies), Shi Jie (Damp Scabies), Chong Jie (Insect Scabies), Sha Jie (Sand Scabies), and Zi Jie (Purple Scabies). They appear like small rashes, are dry, and itchy. This is caused by wind-heat insects. Internal administration of Jie Ling Dan (Scabies Spirit Pill) and external application of San Huang Dan (Three Yellows Powder) will lead to self-healing. (From *Yizong Shuyue*)
*Yizong Xinfa* stated: Scabies has five types: Dry, Damp, Insect, Sand, and Pustular. If Lung Meridian dry-heat is excessive, Dry Scabies occurs, characterized by itching, dry skin, and white scales. If Spleen Meridian dampness is excessive, Damp Scabies occurs, characterized by swelling, pain, yellow fluid upon rupture, and potentially black fluid in severe cases. If Liver Meridian wind is excessive, Insect Scabies occurs, characterized by intense itching penetrating to the bone and insensitivity to scratching. If Heart Blood stagnates, Sand Scabies occurs, resembling fine sand grains, with redness, itching, pain, and fluid upon scratching. If Kidney Meridian damp-heat exists, Pustular Scabies occurs, resembling bean-sized lesions, with itching during bowel movements/urination and clear, pale pus. Alternatively, if Spleen Meridian dampness is excessive, Pustular Scabies also occurs, but the top contains thick pus, with combined itching and pain being the distinguishing feature. Weak individuals may also suffer from this; constipation indicates excess syndrome, while loose stools indicate deficiency syndrome. However, some deficient patients have dry stools; for instance, Qi stagnation leads to dry stools, and dryness of the Blood aspect leads to difficult passage. Differentiation should also be made based on the color and shape of the sores and the strength or weakness of the pulse.
