Eucalyptol

Eucalyptol, sometimes referred to as “cineol,” is a terpene found in the cannabis plant, eucalyptus trees, and several other commonly used plants such as bay leaves, cardamom, tea tree, and sage. It has a vibrant fresh scent that is often described as minty and cooling. Research suggests eucalyptol may help with sinus infections and pain, as well as decrease blood pressure and improve cognitive function for those with dementia. 

“There might be enough eucalyptol in this coughdrop to soothe your throat.”

What is eucalyptol used for?

One of the most common uses of eucalyptol is to relieve sinus and nasal congestion. Specifically, double-blind, randomized, placebo-controlled clinical trials suggest it’s safe and effective for the treatment of rhinosinusitis, or a common sinus infection.

There is also evidence that it can effectively treat pain. In one study, recipients of total knee replacement surgeries reported a decrease in pain and demonstrated a decrease in blood pressure when using eucalyptol by comparison to almond oil.

Moreover, eucalyptol has been shown to have potential benefits for cognitive function in elderly people. In a study of eucalyptol’s effect on the cognitive function of cognitively impaired nursing home residents, patients’ Dementia Behavior Disturbance Scale (DBD) scores improved significantly after taking it, even though no subject reported perceiving the scent.

How do you use eucalyptol?

Eucalyptol can be used in various ways, but is generally inhaled through traditional aromatherapy methods—diffusing oils, as well as burning candles or herbs. In cannabis, look for products with lab results showing high levels of eucalyptol. It is found in high amounts in cannabis strains like Dutch Treat, Girl Scout Cookies, and Super Silver Haze.
