Don’t be scared by a name that sounds like a chemical. Essential Oil chemicals are naturally within the plants. Chemical components in essential oils give the oils natural therapeutic effects. Terpinen-4-ol is a great example. Oils rich in terpinen-4-ol are great for dealing with infection and helping to support the immune system.
Plai (Northeastern) Zingiber cassumunar, Sweet Marjoram Origanum marjorana and Tea Tree Melaleuca alternifolia have significant amounts of Terpinen-4-ol.
Want to know the nitty gritty scientific facts about this component?
- Terpinen-4-ol works by suppressing 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: (1) replenish resident macrophages and dendritic cells under normal states, and (2) in response to inflammation signals, monocytes can move quickly to sites of infection in the tissues and divide/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.

Love this helpful info! It is nice to have it written like this in a small, digestible portion. Thank you.
Thanks Laura, I appreciate your comment!
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.
