Terpene Isolates 101: Eucalyptol (AKA: Cineol)

If you're just getting started with terpenes, odds are you're wondering how each isolate can be used. Terpene isolates can be used in hemp, CBD, and cannabis products as well as concentrates, vapes, foods, beverages, and aromatherapy infusions. In fact, adding terpenes to health and beauty products, cosmetics, vaporizers, foods and beverages, and aromatherapy infusions is a great way to add an extra boost of body-nourishing benefits to your products and make THC/CBD products more effective. This week, we're diving deeper into the cooling, mint-scented terpene known as Eucalyptol.

Eucalyptol Isolate

Eucalyptol, also known as Cineol, is most commonly found in eucalyptus trees. This terpene offers a huge variety of benefits for the mind and body and offers a cooling, menthol-like aroma to cosmetics, aromatherapy infusions, and vape products. It only makes up about 0.06% of a cannabis strain’s terpene profile, but it can be found in many other beneficial plants and essential oils.

You can find Eucalyptol as a flavoring agent in many health products, including Vick’s Vapor Rub, toothpaste, cough drops, and pain-reducing lotions and creams. It can also be found naturally in a variety of spices, herbs, and foods. Below, you’ll find everything you need to know about Eucalyptol terpenes, their benefits and uses, and where you can find them naturally.


Benefits of Eucalyptol Terpenes

There are several benefits associated with Eucalyptol. However, it’s important to note that in high doses it can be toxic when ingested. While the lethal dose of Eucalyptol is a very large amount in rats, there isn’t a lot of data available for how much Eucalyptol is too much for humans. Always consult your doctor before beginning any supplement regimen with terpenes to rule out possible complications.

In normal doses, like the small amounts you get from eating Eucalyptol-rich foods, Eucalyptol offers a variety of benefits to the mind and body. Like most of the terpenes we’ve covered, Eucalyptol is a natural antibacterial agent. It can help kill or reduce the spread of bacteria, viruses, microbes, and fungal spores. In a study, Eucalyptol was able to kill e.coli, staph, and more. Another study showed that Eucalyptol could also be a viable treatment for treatment-resistant strains of tuberculosis. Also like many terpenes, the cooling mint scent of Eucalyptol can repel and kill some insects.

Eucalyptol is also very popular in aromatherapy. Inhaling eucalyptol can reduce pain and lower blood pressure. However, it’s frequently added to things like cough drops and cold medicine for its ability to reduce inflammation in the lungs and airways and help suppress coughs. Studies have shown that Eucalyptol can improve lung functionality and reduce the symptoms of asthma when inhaled through a humidifier or an essential oil diffuser. Last but not least, it can successfully treat sinus infections.


When applied topically, Eucalyptol can improve circulation and decrease pain. It has the ability to directly antagonize receptors to prevent them from sending chemicals that relay the message of pain. It’s a popular terpene to add to cosmetics and beauty products for its soothing cooling effects. You can find it in things like Vick’s Vapor Rub to help improve breathing and clear airways. It’s even used in some arthritis creams, like Bengay for its pain-reducing and circulation-improving properties.

Eucalyptol offers a lot of physical benefits, but it’s also shown to be helpful for mental clarity. It helps balance sleep patterns and boost your mental state to keep it functional. Most interestingly, it’s being studied as a potential treatment for some of the symptoms of Alzheimer’s for its ability to reduce inflammation in brain cells and neuroreceptors. It may even make it easier for you to focus!

When taken internally, Eucalyptol has shown its ability to prevent both the spread of malignant cells and the creation of cholesterol. In one study, Eucalyptol was able to cause colon cancer cells and leukemia cells to self-destruct (apoptosis).


Natural Sources of Eucalyptol Terpenes

Eucalyptol is most commonly found in eucalyptus leaves, though you can also find it in turmeric, rosemary, and ginger. However, it can also be found in small concentrations in plants that contain earthier terpene profiles high in a-phellandrene, myrcene, and b-caryophyllene terpenes. In cannabis, Eucalyptol only makes up around 0.06% of a strain’s complete terpene profile. Strains higher in Eucalyptol include Headband, Super Silver Haze, and Bubba Kush.

Common Uses for Eucalyptol Terpenes

Whether through your favorite fruits and herbs or through a diffuser, Eucalyptol isolate smells and tastes great and works wonders within your body.

Eucalyptol terpenes can be safely added to all sorts of products to reduce inflammation, soothe airways and help with a variety of other ailments. It can safely be eaten, drank, infused, and inhaled with a little bit of mixing. It can also be used to improve cannabis products like vapes and concentrates that may have lost cannabinoid potency or terpene content during extraction.

Add Eucalyptol terpenes to foods and beverages to enjoy the anti-inflammatory, breathing-improving, and antibacterial properties within the whole body. A dash of water-soluble Eucalyptol terpenes in your favorite foods or beverages add a menthol-like mint flavor that can help improve your breathing, freshen your breath, and reduce pain and inflammation.


Add Eucalyptol terpenes to essential oil diffusers and aromatherapy infusions to kill airborne bacteria, viruses, microbes, and fungal spores and help you breathe easier. The bright minty aroma is also great for promoting energy.

Add Eucalyptol terpenes to cannabis concentrates and hemp oils made from strains with higher citrus/floral terpene content, such as Pinene or a-Phellandrenel since Eucalyptol is often found alongside these primary terpenes. Try it in products made from strains like Girl Scout Cookies, Super Silver Haze, and Headband. Eucalyptol terpenes can make them smell and taste better and boost the potency of THC/CBD effects.
