melpatbat:Arnica helps as well. It's a homeopathic remedy that comes in a cream form or the little balls that you dissolve with water.
You can also by a gel formula, too. You have to rub it in only a couple of times and no bruise or swelling.Dr. Oz recommends it.
A friend swears by vitamin E. You buy it in gelcaps and pop it open on the bruise.
