I'm writing this to offer newcomers to aromatherapy some guidance.
There are, of course, more elaborate, more thorough, and more expensive ways to check the purity and/or quality of an essential oil, but here I'm just describing some simple techniques we can try in the comfort of our own homes.
The main thing to remember about all these tests is that none of them is sure-fire—and that's a two-way deal.
Some adulterated oils may pass the “tests” with flying colors; some perfectly good oils may fail them.
If your most beloved, tried-and-true oil fails one of these tests, it may not be the oil's fault!
