Are you wondering about the Vitality Line, and which oils are safe to ingest and which are not? I was as a little confused at first as well. I think you'll find this statement taken directly from Young Living's blog helpful:
There’s no difference in purity and authenticity when it comes to our Vitality™ oils and our topical/aromatic oils, but our Vitality line is clearly labeled for internal use.
