Monoterpenol-rich Essential Oils

Essential Oil Science & Chemistry Corner

Some of us are really curious about the chemistry of Essential Oils. I have so many questions in my head at times as my Aromatherapy Certification doesn’t leave any details out. The reason I personally think it is important to understand the chemistry of our oils, is beyond the aroma only. I can’t tell you how empowering it is, being able to help somebody by understanding my oils and to mix the right oils together for a therapeutic effect.

With the growth of Essential Oils in our regular lives, many of us start out with Essential Oils and might feel lost after a while. The options of mixing truly working blends is an art and it is chemistry.

Essential Oils are fascinating to me and for my own good I created the “Essential Oil Science & Chemistry Corner”. For the real nerdy ones. It will be my reference guide and maybe you will find some use in it too. Let me know if you have anything to add or discuss. I’m happy to chat.

Properties of monoterpenol-rich oils:

  • Antifungal
  • Antibacterial
  • Antiviral (some of them)
  • Anti-infectious (as they are alcohols)
  • Antiseptic
  • Mostly non-toxic 
  • Mild when using them in skin-care products
  • Warm and cooling properties (like Peppermint ~ cooling)
  • Nourishing to the immune system
  • Some of them have a sedating effect (Clary Sage and Lavender for example are great for sleep-less nights)


  • Mostly these are all safe oils when applied and used correctly. The only caution I would spell out is Peppermint as mossible skin-irritant. Peppermint should not be used for children under 5!

And here is my recipe for monoterpenol-rich oils:

No matter where you get your oils from. If you would like to mix for therapeutic effects you will need to know and familiarize yourself with the suppliers GC/MS reports. They must provide you with the reports and preferable BEFORE you buy your oils. There is so many fake oils on the market and suppliers can label them as they’d like due to missing label guidelines.

For me it is very simple, if my supplier doesn’t supply me with the GC/MS report, I will not buy from them. You do want to know what you spend your money on. Especially when they are supposed to be “therapeutic, pure, organic oils”.

As always, Thank you for reading!
