Witch hazel is an ancient and widely trusted home remedy for many different afflictions, including bruises. When you bruise yourself, you have broken certain blood vessels beneath the skin, and these must be healed before the bruise and tenderness will disappear. Witch hazel is an excellent stimulant for the healing process, and can also work to reduce the inflammation and swelling that follows an impact injury. You should be pain-free and your skin should be clear within a few days of regular application of witch hazel.
