Like sage and eucalyptus, tea tree is a camphor, which means it has a lot of the same beneficial properties. When used in its essential oil form, the pungent but strangely delightful smelling tea tree oil is body care gold. It's naturally antifungal, antibacterial, antiseptic, antimicrobial and antiviral. And it's affordable, to boot. It's most typically found in soaps and shampoos, but is also popular in lotions and face care as well because of its anti-acne properties.
