In the last post on Eucalyptus,, I wanted to keep talking about 1,8-cineole because there is so much to learn! Realizing that the blog would be a ramble down a rabbit-hole, I decided to make this a part 2. The chemical component in most eucalyptus is 1,8-cineole. But it is also in Rosemary, Ravintsara and cardamom, so let’s learn more about these Oxides.

The percentage of high 1,8-cineole rich oils.

  • Helichrysum ct. Gymnocephalum 59%
  • Hyssop ct. 1,8-cineole 56%
  • Ravintsara 56%
  • Niaouli ct. 1,8-cineole 54%
  • Cajeput 48%
  • Laurel leaf 46%
  • Rosemary 42%
  • Saro 39%
  • Cardamom 32%
  • Myrtle (red) 31%
  • Spike lavender 29%
  • Rosalinda 29%

There is significant 1,8-cineole content in all the oils listed above, if there are safety concerns with this component it is good know. Always research oils before blending.

In future blogs, I will go into more of the individual oils listed above. For now, I just want to focus on the chemical components.

Helichrysum gymnocephalum is a 1,8-cineole rich oil at 59%. This percentage is almost as high as the percentage in radiata.

Uses for cineole-rich oxides other than a cold.

Cardamom is an anti-inflammatory and an analgesic. It is best used for digestion, but can be irritating to the skin and mucus membranes. Use at a dilution of 1% or less in blends.

Spike lavender has many therapeutic benefits: Anti-inflammatory, analgesic, antibacterial, antifungal as well as being a decongestant and expectorant. This oil is also high in linalool at 45%.

Ravintsara is analgesic, anti-inflammatory, antibacterial, antifungal and antiviral.

Rosemary is also many of the above, plus a CNS stimulant for memory and alertness. Rosemary is rich in a-pinene at 12% and camphor at 11% which enhances its therapeutic benefits.

So, the point is—if 1,8-cineole is a problem for you, there is more than Eucalyptus to research and be concerned about.

Safety is always the first concern when working with essential oils.

Happy Blending,
