I was not aware that there was a cherry essential oil. I could be wrong. I haven't looked it up. You might be talking about an absolute or fragrance. If I find one, I am sure it would be expensive, because I don't know any suppliers that have it, or more likely, even possible.
Sorry, I found a cherry extract, but not an essential oil. I also looked it up in my book and it's not listed. I think if you find an essential oil, it is fake or not a true essential oil (absolute, extract, infusion, etc). One doesn't exist.
