Eucalyptus oil is one of my all-time favorite oils to use. I use it for colds, allergies, and for just the smell of it! Making your own soap can be one method of utilizing eucalyptus essential oil, rather than just burning it.
I always use this recipe from diynatural.com when I need to make a batch of soaps. When the step comes to add oils, I just dropped about 20 drops of eucalyptus oil in the mixture. As always, I use Barefut oils. They’re the most convenient, cost-efficient, and therapeutic (in my opinion).
