The outstanding scent and valuable chemical constituents of our certified organic Narrow Leaf Eucalyptus (Eucalyptus radiata) makes it our favorite Eucalyptus essential oil – its aroma is refreshing, very diffusive, penetrating, cineolic, with subtle citrus and peppery-floral overtones. Narrow Leaf Eucalyptus is also known as Grey, Black or Narrow-Leaved Peppermint Eucalyptus. It is extremely beneficial for the respiratory system and provides gentle yet superb immune support that is particularly appropriate for children and elders.
