I don't wear this oil (it has a dominating menthol aroma), but I put maybe 4-5 drops in to a spray bottle with about 6 oz. of rubbing alcohol. I use this mix to spray down our bedding (sheets, pillowcases), and our fabric couch, as well as the fabric bathmat and sneakers and insides of shoes and boots.
I believe it slows down the accumulation of body odor and mustiness in general, as well as helping to open up the breathing passages.
Very useful.
