And some states have legalized cannabis and its terpenes. You will always want to check to understand the regulations in your state to assure you are using a legal substance.


How Does Eucalyptol Play a Role in the Cannabis Plant?

Not only do terpenes like Eucalyptol give cannabis products their distinctive aroma, but they also possess the ability to enhance the health effects of cannabinoids.

Although it has medicinal benefits on its own, it also plays a role by contributing to the entourage effect.

The entourage effect is a term that describes how cannabis components, such as CBD, THC, and terpenes, work together in synergy. Early research has observed that terpenes work side by side with cannabinoids to boost their beneficial health effects. [13] 

The sum of all the parts, such as cannabis combined with terpenes, produces more significant health advantages than each individual substance alone. This process is the entourage effect. Eucalyptol is not as abundant as some other terpenes, like humulene.
