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.
