Eucalyptus Organic Essential Oil is probably most well known for its wonderful benefits for respiratory applications including helping to ease congestion and pressure, colds, flu, fever and bronchitis. It's also a great essential oil to use in massage or other topical blends to ease muscular pain and arthritis.rnEucalyptus Essential Oil primarily consists of the oxide 1,8 cineole (also known as eucalyptol or just cineole). The cineole content is what is primarily responsible for giving Eucalyptus globulus its aroma and key therapeutic benefits for respiratory health and pain relief.
