10 of the Best Essential Oils

7. Eucalyptus Oil

Consumers will find eucalyptus oil in an array of medicinal products for the treatment of respiratory conditions, sinus congestion, influenza, the common cold, and joint pain due to its antibacterial, antioxidant, antiseptic, and anti-inflammatory benefits.

However, there is little scientific documentation available for these specific uses, so effects may not be pronounced. People who take medications for seizures or ADHD should check with a physician before using eucalyptus oil because it can lower the effectiveness of these prescriptions.
