May reduce pain

Inhaling eucalyptus essential oil may help to alleviate discomfort. Many anti-inflammatory chemicals, such as cineole and limonene, are found in eucalyptus and may work as pain relievers. A three-day study of 52 persons who had knee replacement surgery discovered that breathing eucalyptus oil dissolved in almond oil for 30 minutes every day significantly reduced reported pain and blood pressure levels when compared to inhaling pure almond oil.

Another study of 123 cancer patients revealed no reduction in felt pain after breathing eucalyptus oil for 3 minutes prior to medical treatment, indicating that additional research is needed.
