Limonene
Bright citrus — lemon, orange peel, grapefruit
Limonene is the citrus terpene, and the second-most-common terpene in cannabis. Patients often describe limonene-forward products as uplifting, mood-brightening, and less physically heavy than myrcene-dominant strains. It's a common go-to for daytime medicating.

Deep dive
Limonene has some of the strongest published research of any cannabis terpene for anxiety and mood. Isolated limonene has been studied for anti-anxiety effects at doses far higher than what appears in cannabis — but the entourage effect (terpenes and cannabinoids working together) means small amounts in a full-spectrum product can still contribute meaningfully.
Patients treating PTSD, depression-adjacent symptoms, or general anxiety often gravitate to limonene-forward products because they don't produce the couch-lock that myrcene does. Limonene is also part of why some citrus-forward strains feel 'cleaner' — you can function on them.
On a Kentucky COA, limonene above 0.3% is meaningful. Above 0.5% and it will usually be the defining note of the strain's aroma. Look for products where limonene is stacked with pinene for daytime clarity, or with linalool for a calmer citrus profile.
