Onion
Studies show that a kitchen ingredient like onion can be used to treat minor cuts. Onions contain Allicin, which is an antimicrobial compound that helps prevent wound infection. When you get a small cut or wound, the first thing to do is to apply a disinfectant on the injured area. Onions have anti-inflammatory features that help reduce inflammation and heal various wounds. The simplest way to use onions for this purpose is to blend it and make a paste out of it to apply on the wound. This will help kill bacteria before it is able to spread infection.
