I did a few booths at local shows this past week and one of my favorite things to tell people is how easy it is to use oils. When you first start, they can be so overwhelming. My favorite tip is putting distilled water and a few drops of oil into an essential oil safe bottle- buy a 4-pack here- and easy peasey, room spray! Shake before you use each time, I use on my sheets for bedtime, in the bathrooms, and in my boys' stinky shoes. So easy and so much better for you than the store-bought chemical air fresheners.
Some scents that work well for this is cinnamon leaf, peppermint, and orange. Roman Chamomile is great for sleeping. You can even mix and match!
