You mean olive oil will kill it if injested or if you apply it topically?
Both... It is called organic oil of oregano it comes in a tincture and you take 30 drops two to three times a day...This is not like the food grade you cook with, although that is healthy on its own. I'm told that topical and injested is a strong defense for staph. My daughters doctor also told us to give her collodial silver.
