Scabies, a kind of skin disease frequently seen in the period of Warring States and Qin-Han Dynasties. By investigating the epidemic condition, disease title, recognition on the disease and the prevention and its treatment through the textual documents, unearthed texts, and dictionaries of this period, it can be seen that ＂scabies＂ refers to the itching and corrugation of skin. It was also called ＂jia＂ （scar） and belonged to the ＂dry itching＂ disease. At that time, people also knew the seasonal, and geographical rules of its incidence and its pathogenic agent, the scabies parasite （ sacoptic mite）. Treatments included hot compress, rubbing, bathing, and internal medications, mostly inherited in later generations.
