has it ever been opened? just for like smelling purposes? (i only ask because I'm highly allergic to eucalyptus but my mom really likes it LOL so if I was to win this auction and the eucalyptus had been opened at one point could I request like clear wrap (like what you use to wrap food up) to go around the eucalyptus just in case it leaks. I'd really hate to spend my christmas in the hospital LOL!
