顾世澄说：八角虱就是八角虫，又名阴虱疮，其形状像花蜘蛛，叮咬在阴毛之上，生长在前阴部的毛际处。瘙痒感如同锥刺一般。病因在于肝肾之气浑浊产生热邪，加上淫欲过度且缺乏清洗，导致二精不洁，郁滞而成。瘙痒难以忍受，抓破后颜色发红，中间含有紫点，适宜内服芦柏地黄丸为主进行治疗。
又说：这种虫子最容易传染，得了此病的人不要接近女子，如果接近，妇女就会生出这种虫子，不可不谨慎。

It bites onto the pubic hair and grows at the junction of the anterior yin region. The itching feels like being pierced by an awl. The pathogenesis involves turbid Qi of the Liver and Kidney generating heat, combined with excessive sexual desire and lack of hygiene, leading to impurity of essence and stagnation. The itching is unbearable; scratching causes redness with purple spots in the center. Internal administration of Lubai Dihuang Wan (Lubai Dihuang Pill) is indicated as the primary treatment.
