Gingerol and ginger extract has been known to decrease the growth of bacteria and can be helpful in fighting infection in open sores, minor cuts, or scrapes. Ginger oil can be applied to the wound topically to keep the area clean and to prevent infection. It can be used as a natural antiseptic the next time you have any minor cuts or scrapes, but it should not be used as a sole treatment, especially for larger or more severe wounds.
