Lemon Eucalyptus has a fresh, lemon, medicinal aroma. It is a good addition to inhalation and room spray formulations that are intended to help combat cold and flu symptoms and germs due to its antibacterial and antiviral properties as well as minor first aid treatment for cuts, infections, fungal infections, bacterial infections, and chickenpox. For hair, it can be added to shampoo formulations to assist with dandruff.
