The best way to heal a bone bruise is to allow your body to do its job the best it can. This means avoiding strenuous activities that can "re-bruise" your bone. Even slightly hitting that same bone again can undo all the repair that your body has started and make the healing process start all over again. It takes time for the new bone and calcium to become super strong, so you have to be tender with a bone bruise to allow the bone to repair most successfully.
