Receptor targets
5-HT1A · TRPV1 · GPR55 · CB1/CB2 (negative allosteric modulator)
Mechanism of action
Acts on serotonin (5-HT1A) and vanilloid (TRPV1) receptors and dampens CB1 signalling as a negative allosteric modulator rather than a direct agonist, which is why it does not produce a 'high'.
Reported effects
Common terpenes
