Dear Christina,
I know very little about the use of 'essential oils' as a trend, which is occurring today. However, it seems to me that if you use the oils — which are natural by-products of vegetables — with no spiritual or occult intention, there wouldn't be a problem.
In other words, if oil is used for food or medicinally, and you're not piggy-backing on any so-called spiritual or occult wish or claim, it's probably fine.
Let's see if my colleagues would like to add anything to this.
