Bruises occur when a blood vessel is ruptured and blood pools in the tissue around it. Bruising often results from impact, but can also be caused by bacterial or viral infections. It can also occur when blood doesn’t clot well.Structured silver helps remove the blood from the tissue, improving the bruise. Simply soak a sterile bandage in liquid silver and place it on the bruise. Structured silver gel can also be applied to the wound one to four times a day.
