I love using essential oils. Even took a course in it once and used to teach it (as well as making your own liquers) at pagan festivals
A friend of mine started making bath and cosmetic products because of her sensitivities, with combinations of essential oils maximized for therapeutic effect. Bar none, they are the best things ever. Lip balm, foot scrubs, green clay facial masks - they're all better than any commercial product I've ever come across.
I hope you can continue with your instructional essential oil sessions in some venue. I'm not a big proponent of alt health remedies, but I've found essential oils to have real benefit, especially given that they have such a long history of being used to great effect medicinally. Fortunately, we're no longer burned at the stake for such knowledge. At least not literally.
