i LOVE eucalyptus EO, use it more than anything else as an anchor in blends. i especially love it with white thyme, but that's prone to seizure. it blends wonderfully with mints, herbals like rosemary and thyme, juniper, ginger, etc. one of my absolute favorite blends is eucalytus and fir or spruce. be adventurous with it, it's hard to go wrong with eucalyptus!
