Hello: No matter what the disease is, I think it is unscientific and undesirable to use your father's method! ! If it is scabies, 1% sulfur ointment (5% sulfur ointment for infants) is generally used externally. Before treatment, take a bath with hot water and soap, and then apply medicine, from the neck down, first to the skin lesions, and then to the whole body, once or twice a day, for 3-4 days as a course of treatment. During the application, do not take a bath or change clothes, so as to maintain the efficacy and completely eliminate the scabies on the skin and clothes. After the treatment, change to clean clothes.
