Our tea tree oil soap contains two "Melaleucas", Australian Tea Tree and Cajeput. Most people know "Melaleucas" (tea tree oil genus)as having great anti bacterial agents, great for acne, fighting fungus, etc.. Cajeput has a bit more "woodsy" smell to it, similar to Eucalyptus but a touch less "camphorous". We put generous portions of both oils in this bar for a healthy, lathery shower.
