20 Genius Hacks to Heal Bruises Naturally
13. Raw Potato Poultice

This old-school remedy might sound odd, but raw potato slices contain enzymes and starches that naturally reduce inflammation and promote skin healing. Grate a chilled raw potato, wrap the pulp in cheesecloth or a clean thin cloth, and place it directly on the bruise for 20–30 minutes. The coolness soothes the area while the compounds in the potato help break down dried blood under the skin. Repeat twice a day for best results. This trick is especially effective in the early stages of a bruise and is gentle enough for use on children.
