Aroma oil burners are simple and easy to use; they cost little, and, properly taken care of, will last indefinitely. ... Unlike incense, the burning of essential oil in an aroma oil burner produces no smoke, and leaves behind no ash or debris.
To use your oil burner, find an oil you like. I like to use oil blends as well as patchouli, geranium or peppermint.
In aromatherapy, you should never diffuse more than an hour long of any essential oil, but some more potent oils or blends should only be diffused for 20 minutes! Another issue with diffusing essential oils is pet safety, please make sure your oil burner is out of your pets reach.
Place 3-5 drops of the oil together with some water into the top of an oil burner until it's 1/2-3/4 of the way full. The oil/water mixture will start to heat and evaporate, scenting the room
