There are some rules you need to know on how to buy essential oils especially with buying essential oils on the internet.
Quality and Safety Control
Essential oils that are used in aromatherapy are not always easy to find. The Food and Drug Administration does not regulate essential oils so you, the consumer, will have to carefully read the ingredients of any oil you purchase to make sure that it is in its purest form.
In order to get the most benefit from aromatherapy, oils in their purest form should be used.
Finding the Best Essential Oils
Try to avoid synthetic oils. Essential oils are the only way to get therapeutic benefit from aromatherapy. They will not be cheap nor should many different kinds of oils be priced the same as the process of distilling them is varied.
Light exposure decreases the ability of an essential oil to work, so only buy oils that are sold in dark bottles.
The term “oil” is often a misnomer as many of them are not at all oily. To test how distilled an oil is try dropping it on a piece of paper to see if it dissolves quickly and does not leave an oil spot.
If you have a health store in your area shop there instead of a perfume store. It is more likely that they will have real essential oils for sale.
