Lice

Lice disease (pediculosis) is a kind of itchy skin disease caused by lice parasitizing on the human biting skin. The response to lice bites varies from person to person. After repeated bites, a sensitive reaction occurs, and itching and rash appear. Some people do not respond after repeated bites. The first bite does not respond. The principle of treatment is to kill insects and eggs, and it is best to shave the head and pubic lice first. The commonly used drugs are 50% pupa (Chinese pupa is immersed in dilute alcohol or white wine, filtered after 24 hours for backup), 20% benzene Benzyl formate emulsion and the like.
