Not only is it great for travel, but also for winter season cold/flu prevention. You can put a drop on your hands as a natural hand sanitizer (make sure not to rub your eyes!) or just take a deep inhalation before or after being in a crowded or contaminated space.
Make your own:
4 parts Clove Essential Oil
4 parts Cinnamon Essential Oil
2 parts Eucalyptus Essential Oil
1 part Lemon Essential Oil
1 part Rosemary Essential Oil
**Other optional immune boosting oils: Tea Tree, Sage, Lavender, Thyme
**Use a base oil like sesame, almond, or jojoba to make the blend last longer.
