Arnold, Iain S., McGregor and Mark Connor Cannabis and Cannabinoid Research, 2019, Vol. 4, No. 3 doi : 10.1089/can.2019.0016 Abstract Introduction: Compounds present in Cannabis sativa such as phytocannabinoids and terpenoids may act in concert to elicit therapeutic effects. Cannabinoids such as Δ9-tetrahydrocannabinol (Δ9-THC) directly activate cannabinoid receptor 1 (CB1) and cannabinoid receptor 2 (CB2); however, it is not known if terpenoids present in Cannabis also affect cannabinoid receptor signaling. Therefore, we examined six common terpenoids alone, [...]
