Smells like chemicals, not eucalyptus. Acerbic, unpleasant, probably artificial smell. I have eucalyptus essential oil that I love, and this is entirely different. I burned it for a couple hours, hoping that the chemical smell would burn off, but it smelled horrible the whole time. I’m really bummed because I really like both these herbs, but whatever this is, it’s not those smells. I had to trash it. I wouldn’t give this to an enemy. Well … maybe if I actually had an enemy, I would.
