Research notes below describe isolated terpene mechanisms and early findings. They do not guarantee effects from this strain and are not medical advice.
Russo 2011: naloxone-sensitive analgesia, potentiates barbiturate sleep; dominant sedating terpenoid; blocks hepatic carcinogenesis by aflatoxin.
~28%
spicy
●●○○
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: sedative properties; enhances transdermal pharmaceutical penetration; antimalarial; PMC11060501: GABAergic-mediated antinociception.
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.
⚡
energetic
morningAssociated with ocimene/terpinolene profiles; stimulating without sedation; largely emergent from absence of sedating compounds rather than a direct mechanism.
△
uplifted
morningLimonene anxiolytic/antidepressant via serotonin elevation in prefrontal cortex (Russo 2011); mood improvement without full euphoria; key for balanced-1-1 profiles.

How accurate is this data?
See the "Data confidence" card in the sidebar. Terpene profiles and effects are chemistry-informed estimates — individual responses depend on phenotype, source, and personal chemistry.
