DON'T: Don't buy perfume oils thinking they are the same thing as essential oils. Perfume oils do not offer the therapeutic benefits of essential oils. Even if you only intend on using aromatherapy in your lifestyle for the sheer enjoyment of the aroma, essential oils that are breathed in can offer therapeutic benefits. These benefits do not occur with the use of perfume oils.
DON'T: Don't buy essential oils with rubber glass dropper tops. Essential oils are very concentrated and will turn the rubber to a gum thus ruining the oil.
DO: Be selective of where you purchase your essential oils. The quality of essential oils varies widely from company to company. Additionally, some companies may falsely claim that their oils are undiluted or pure when they aren't.
DO: Learn to compare apples to apples when shopping for oils. Anise, Lavender, Bay, Cedarwood, and Eucalyptus are examples of the common names of plants used to create essential oils. There are different varieties of each of these plants. To differential these varieties, the botanical name (also referred to as the Latin name) is used to tell them apart.
DO: It is also helpful to note the country of origin for the oil. Most good essential oil sellers will readily supply the botanical names and country of origin for the oils that they sell. When comparing one company's oils with another's, also pay attention to if either company's oils are organic, wild-crafted or ethically farmed.
DON'T: It is wise not to purchase oils from vendors at street fairs, craft shows, or other limited-time events. Some vendors know beginners have no recourse against them later. This is not to say that there are not highly reputable sellers at such events, but this is a caution for beginners who are not able to reliably judge quality.
DO: Purchasing oils from reputable mail-order companies may result in obtaining higher quality oils at less expense than purchasing oils from a generic local health food establishment. Again, there is a wide variance in the quality of oils from company to company and store to store.
DO: Store your oils in dark glass (amber or cobalt blue) and in a cool, dark place. I have two wooden hinged boxes that I store some of my oils in. Unfinished wooden boxes may be purchased at craft stores. These boxes allow me to move my oils from different areas of the house easily. Wooden floppy disk holders can also serve this purpose well.
DO: Pay special attention to all safety information on all essential oils that you use. This is even more important if you have any medical condition or are pregnant.
