Green ointment is actually a topical gel preparation, and the main ingredients of this gel preparation are actually lidocaine and lincomycin. These two drugs, one is an antibiotic, one is a narcotic anti-itch drug, generally in clinical use mostly for some epidermal mild burns and mild trauma, etc., so that can play a certain anti-infection and anti-inflammatory effect, but also has a certain narcotic anti-itch effect and pain relief, such as just due to skin trauma and the formation of local tingling, so that can play a certain pain relief effect. But this ointment can not be used for a long time, because after all, it contains some antibiotics, which are mainly for septic diseases formed by gram-positive bacteria infection, such as Staphylococcus aureus. The use of this ointment when the skin is just traumatized can contain the local infection to a certain extent.
