For thousands of years, people have enjoyed the fresh earthy scent of eucalyptus plants. However, scientists only recently discovered what gives the eucalyptus genus its distinctive aromatics. One terpene called “eucalyptol” or “cineol” seems to be responsible for eucalyptus’s cooling properties. Interestingly, recent data suggests that eucalyptol may be present in many popular CBD hemp strains.

When evaluating Certificates of Analysis (COAs) for full-spectrum CBD oils, you may run across eucalyptol. Therefore, it’s important to know the potential flavors and effects eucalyptol produces. 

How Does Eucalyptol Make CBD Hemp Strains Smell?

If you have experience sniffing the eucalyptus plant, then you know how difficult it is to describe its distinctive aromas. However, most people who’ve encountered eucalyptus suggest it has “cooling” properties. While eucalyptol may not be the same as mint or menthol, it’s naturally present in mint leaves. Therefore, it’s common to compare the eucalyptol terpene with the flavors you’d expect from fresh mint sprigs.

Words often used to describe eucalyptol include “herby,” “earthy,” and “floral.” Hemp strains with higher concentrations of eucalyptol may have a “chilly” effect on your throat, potentially reducing coughing. Hemp smokers may also report flavors that remind them of a refreshing walk in the woods. 

Note: Eucalyptol rarely dominates a hemp strain’s terpene profile. Unlike limonene or myrcene, eucalyptol is a “secondary cannabinoid,” which means it tends to play a supporting role. You may not notice eucalyptol’s full force until you gain more experience testing various CBD hemp strains. 

Does Eucalyptol Have Any Special Benefits? 

There’s not much data on eucalyptol’s benefits, but some studies suggest it has potential therapeutic properties. Most significantly, some doctors believe eucalyptol can naturally decrease inflammation, especially in the sinuses. Indeed, some trials suggest eucalyptol could be a natural aid for sinus pressure and congestion. 

Some early reports suggest eucalyptol’s anti-inflammatory effects may help with pain management and brain health. There are even a few studies that indicate eucalyptol may have neuroprotective effects. However, it’s still too early to draw any definitive conclusions about eucalyptol’s effect on brain issues like dementia. Hopefully, as more scientists look into eucalyptol’s properties, we’ll better understand how it functions on its own and when paired with CBD. 

Always Check Your Terpene Percentages On Third-Party Lab Tests! 

Eucalyptol is rarely the “star of the show” in CBD hemp strains, but it can have a noticeable impact on a CBD hybrid’s scent and effects. People who are interested in cooling & earthy strains will probably appreciate a high presence of eucalyptol. Also, since eucalyptol has a strong association with sinus relief, it may be a great choice for people who struggle with nasal congestion. 

You must examine your brand’s third-party lab results to find out how much eucalyptol is in your favorite CBD hemp strains.
