Loving Terpinen-4-ol

by Andrea on August 12, 2010

terpinen-4-ol-1Don’t be scared by a name that sounds like a chemical!

Essential oil chemicals are naturally found within the plants. These chemical components give the oils their natural therapeutic effects. Terpinen-4-ol is a great example.

Oils rich in terpinen-4-ol are great for dealing with infection and supporting the immune system.

Northeastern Plai (Zingiber cassumunar), Sweet Marjoram (Origanum marjorana) and Tea Tree (Melaleuca alternifolia) have significant amounts of terpinen-4-ol.

And now for the nitty gritty scientific facts about this component!

Terpinen-4-ol suppresses inflammatory mediator production by activating human monocytes. Monocytes are a type of white blood cell–part of the human body’s immune system. Monocytes have two main functions in the immune system:

  • Monocytes replenish resident macrophages and dendritic cells under normal states.
  • In response to inflammation signals, monocytes can move quickly to sites of infection in the tissues, where they divide or “differentiate” into macrophages and dendritic cells to elicit an immune response.

What does this mean exactly?  Basically, terpinen-4-ol gives your body a boost when it comes to fighting infections and illnesses.  Oils rich in this component amplify blends for the flu, colds, and even digestive issues.  Keep it in your back pocket as we approach the cold and flu season!

Hi Andrea. You have such a wonderful way of explaining the chemistry of the oils. Can you speak to the antioxidant aspect of oils, terpenes in particular. Thanks for your expertise and generosity.


Admin November 2, 2010 at 8:58 am

Holly-there is a lot of research on the antioxidant activity of specific essential oils components and individual essential oils. You can go to PubMed (http://www.ncbi.nlm.nih.gov/pubmed) and find many articles on the subject.

Hi Andrea,

Great info!
What is the difference between Central Plai and Northeastern Plai?


Andrea Butje December 8, 2014 at 3:21 pm

Hi Cristina – it has to do with the chemistry of the oil, and in this case you would need to see the GC/MS report for each of the 2 plai oils and then we would know the difference. Hope this helps :)
