Now that you have your essential oils, and are beginning to use them regularly, it’s important that you store them properly. Although essential oils do not become rancid, they do oxidize, deteriorate and lose their beneficial therapeutic properties over time. Oils such as citrus oils will oxidize and begin to lose their aroma and therapeutic properties in as little as six months, especially if they are kept in the heat. The aroma of essential oils such as Patchouli and Sandalwood mature with age. Make sure to store your oils in amber or cobalt blue bottles. All essential oils should be stored in a cool dark place. Value your essential oils, they support you and your family’s health, and should become an essential part of your lifestyle.
