●●○○
Russo 2011: only terpene that is a selective full CB2 agonist (100 nM); Gertsch et al. 2008: acts as dietary cannabinoid; unique anti-inflammatory and gastric cytoprotective properties.
Russo 2011: acetylcholinesterase inhibitor (IC50 0.44 mM) counteracting THC-induced short-term memory deficits; most widely encountered terpenoid in nature; anti-inflammatory via PGE-1.
Effects
Reported effects — derived from terpene chemistry and cannabinoid profile.
creative
morningAssociated with terpinolene/limonene profiles; dopaminergic and serotonergic modulation via limonene 5-HT1A supports divergent thinking.
uplifted
morningLimonene anxiolytic/antidepressant via serotonin elevation in prefrontal cortex (Russo 2011); mood improvement without full euphoria; key for balanced-1-1 profiles.
