As for me (and I believe for many in the field), I do use essential oils internally and undiluted and have for 25 years. I don't think it should be foolishly done nor advocated as if safety concerns are not relevant. But I do believe there needs to be greater education in this area.
The biggest concern seems to be, and rightly so, that given a little room to use essential oils internally or undiluted, then those without proper education will potentially cause injury to self and others because they lack understanding of how, when, why and most of all, how much. To this, I agree.
I would love to hear from you about if and how you have used essential oils either internally or undiluted and how really they have helped with something specific. Thank you!
