Limonene is the second most common terpene in nature and one of the most recognizable cannabis terpenes due to its unmistakable citrus aroma. This cyclic monoterpene is the primary component of citrus peel oils, giving lemons, oranges, and grapefruits their characteristic scent. In cannabis, limonene-dominant strains are typically associated with uplifting, energizing effects.
Clinical research on limonene has shown promising results for mood regulation and anxiety reduction. A 2013 study published in Behavioural Brain Research demonstrated that limonene inhalation produced measurable anti-anxiety effects in laboratory settings. Additionally, limonene has shown potential as an anti-inflammatory and antifungal agent, and its ability to increase the absorption of other compounds through skin and mucous membranes makes it valuable in topical formulations.
For terpene formulators, limonene provides a bright, clean top note that can cut through heavier, earthier profiles. It pairs exceptionally well with pinene for an invigorating forest-citrus blend, or with linalool for a balanced, mood-enhancing combination.
