My husband began using the staph medication on August 8, and immediately saw his infection start to disappear. His knee was swollen, red, and hot. Within a week it was completely back to normal with no actual sore ever forming and no drainage. We've had staph in our family before, and have always treated with prescription medication and been left with several scars. This product will be the first I reach for if we ever have another infection. Calista Stephens
