After 48 hours of ointment is solidified stereotypes. Such as the injury in the neck, armpits, popliteal fossa, prescription thicker, within 48 hours after bandaging internal injuries don't buckling, in case of cream off the skin aging. 10 ~ 15 days to dismantle gauze and lime cream, visible bubble absorption, eschar fall off on their own. To the burning hot area is larger, the wound surface has infected patients, to control infection in time, to prevent shock, keep the balance of water and electrolyte. (4) in the treatment of tinea capitis, in just the weathering of lime half bowl, add water to 1 bowl, stir precipitation after 3 minutes, take the upper emulsion, add 4 drops of tung oil, vigorously, remove excess water make into paste, cha outside affected part.
