Limonene

Limonene is the terpene that hits your nose the moment you peel an orange or zest a lemon — that bright, clean citrus burst. In cannabis, it's one of the most recognizable aromas and is strongly associated with strains that deliver uplifting, mood-boosting effects. You'll find it concentrated in the rinds of citrus fruits, as well as in juniper, peppermint, and rosemary.

Research on limonene has shown promising antidepressant and anti-anxiety properties. Consumers frequently report that limonene-forward strains cut through stress and bring a sense of clarity and positivity without the heaviness of sedating terpenes. It's also one of the reasons citrus-scented strains tend to feel more energizing and social.
