If you love scenting your home, don’t use the commercial air fresheners. Those contain chemicals that are known to cause birth defects and reproductive problems. Instead, make your own. Air fresheners can be made at home. The easiest way to make your own is with a spray bottle, water, some essential oil and a little bit of vodka. If you have some fragrant herbs in your garden, you can infuse them with alcohol for a week then skim out the herbs.
