Anemarrhea is often used clinically for local rubbing after mosquito bites, which can play an anti-inflammatory and swelling effect, but not for external wound rubbing, mainly for the following reasons: First, if the patient’s wound is a clean wound, the wound is not obvious infection and exudate, at this time external rubbing anemarrhea can not play the role of local disinfection, and will not promote faster healing of the wound. Second, for infected wounds should use vital iodine, hydrogen peroxide, saline for wound disinfection, and to remove the local fluid, pus and necrotic tissue. If you use windex, it may cause external bacteria and toxins to enter the infected wound, aggravating the local infection and causing delayed healing of the wound, which is not conducive to faster recovery of the patient.
