Lemon Scented Gum (corymbia citriodora)
A bold, bright lemon-scented eucalyptus that likes to be noticed. It is the best source of citronellal, the active ingredient in citronella, and as such makes an excellent insect repellent. It also has strong antibacterial and antiviral properties. It blends well with eucalyptus, peppermint gum and tea tree. You only need a small amount of this powerful oil in any blend.
