Yes, but it's not the best for your skin or for deeper wounds and infections. (Hydrogen peroxide is harsh on the skin and while it can treat an infection, it's not recommended for deep wounds or sores that may originate below the first couple of layers of skin because it can cause further damage to tissue.) If the boil seems ulcerated, do not use peroxide, but seek treatment in the form of antibiotic therapy to treat the infection or ulceration. Meanwhile, to treat a boil that is not ulcerated and encourage drainage, apply warm most compress as often as possible throughout the day/evening at 30 minute intervals.
