Did you know that 90% of eucalyptus oil is imported from elsewhere and many oils labelled as Tea Tree or Eucalyptus are diluted with pine oil? ETTO medicinal oils are grown and steam extracted on ETTO farms in Western Australian and NSW. Our Pure Tea Tree and Blue Mallee Eucalyptus oils are distilled without the use of chemicals or solvents. They are extracted from the highest grade plants grown for therapeutic purposes (not a by-product of the paper industry like many eucalyptus oils) this means they have a potency of their key bioactive components 1,8-cineole and terpinen-4-ol that is superior to standard oils. With their well known remedial properties, they are truly nature's solution to many everyday problems. Enjoy these 100% pure, potent and great Australian oils.
