Wholesale Certified Organic Narrow Leaf Eucalyptus Essential Oil

100% pure Narrow Leaf Eucalyptus essential oil steam distilled from the leaves of Eucalyptus radiata trees, Certified Organically grown in South Africa. Eucalyptus radiata may be the Eucalyptus with the most broadly therapeutic action and a nice, bright aroma. One of the most important factors in the cineol-rich essential oils is that the stock be very fresh, and we take special care to ensure this quality for you. Our Narrow Leaf Eucalyptus Essential Oil is available from sample size up to 1kg or more.


A relatively smaller variety of this evergreen species, the 'narrow leaf peppermint' Eucalyptus is native to Southwestern Australia and only reaches a maximum height of 15 meters.


This oil is light, clear, and slightly blue-tinted. It is steam-distilled from the leaves of Certified Organically cultivated South African trees. While Eucalyptus generally originated in Australia, there was a great effort to transplant many of the varieties (Blue Gum, Dives, Citradora, etc...) to South Africa in the 1980's. The trees did spectacularly well and their essential oil is of the highest quality.

Aromatherapy Notes

This oil is cooling with bright citrus-like top notes, a camphoraceous middle note and slightly sweet, cedar-like undertones. It blends well with Thyme, Rosemary, Lavender, Marjoram, Pine Cedarwood, and Lemon.

Traditional Uses

The oil and leaves of Eucalyptus are a traditional folk remedy in Australia: the leaves, smoked like tobacco, are believed to improve asthmatic conditions. It is also an effective insect repellent.

Eucalyptus in Research

Eucalyptol (1,8-cineol) is one of the most common and most therapeutic compounds found in essential oils. Named after eucalyptus, it is one of the primary components of eucalyptus oil, making up over 80% of both varieties of the eucalyptus oils we carry. Eucalyptol has been extensively studied in scientific research and has been reported to have strong anti-inflammatory, analgesic (pain-blocking)3, antimicrobial4, antioxidant5, anti-ulcer6, and asthma relieving properties7,8.

Summary of Research Studies

  • Eucalyptol had significant anti-inflammatory, analgesic (pain-blocking), and sedative effects in mice.3
  • Eucalyptus essential oil has been reported to have anti-microbial, fungicidal, insecticidal/insect repellent, herbicidal, acaricidal and nematocidal activities and has been proposed as an effective natural alternative to traditional pesticides.4
  • Both the eucalyptus radiata and globulus varieties showed significant antioxidant and antibacterial activity in vitro.5
  • Cineol (eucalyptol) administered to rats significantly decreased the formation and severity of ulcers in the colon, confirming "the anti-inflammatory action of 1,8-cineole and [suggesting] its potential value as a dietary flavoring agent in the prevention of gastrointestinal inflammation and ulceration."6
  • Application of eucalyptol to human cell culture showed a significant decrease in the production of cell-signaling proteins that cause inflammation airway mucus hypersecretion. The authors suggest that this is evidence that eucalyptol may have a role as a "long-term treatment to reduce exacerbations in asthma, sinusitis, and COPD."7
  • In a clinical trial with patients with steroid-dependent bronchial asthma, daily doses of eucalyptol led to a significant decrease in the patients' dependency on the steroid prednisone to treat their asthma symptoms.8

Application and Use


Externally non-toxic and when in water dilution Eucalyptus oil is a non-sensitizing non-irritant. NOT FOR INTERNAL USE; ingestion of as little as 3.1oz has been reported fatal. If you are pregnant or breast-feeding, consultation with a physician is recommended.
