We’re studying lots concerning the methods THC and CBD work together with the endocannabinoid system (ECS) to stimulate urge for food and assist deal with ache, nervousness, and epileptic seizures. However hashish accommodates an enormous array of minor cannabinoids as nicely. What’s their therapeutic potential and the way do they work within the physique?
These are questions {that a} research from Robert Laprairie’s lab on the College of Saskatchewan sought to reply. They discovered that THC, CBD, and 6 minor cannabinoids—tetrahydrocannabinolic acid (THCA), tetrahydrocannabivarin (THCV), cannabidiolic acid (CBDA), cannabidivarin (CBDV), cannabigerol (CBG), and cannabichromene (CBC)—interacted with cannabinoid receptors and lots of had constructive results in mice.
THC is thought to exert its influence partly by activation of essentially the most well-researched cannabinoid receptors, CB1 and CB2. The pharmacology of CBD just isn’t as nicely understood however is prone to work by interacting with different parts of the ECS, together with different receptors.
All eight cannabinoids examined had some degree of binding to CB1 however, apart from for THC, this binding was weak. Many of the cannabinoids additionally certain to CB2, together with THC, THCV, and CBDA. As anticipated, CBD certain poorly to this receptor.
In mice, they discovered that THC, THCA, and THCV—however not CBD—diminished ache, whereas THC, CBD, THCA, THCV, and CBG all had a constructive influence on nervousness. The authors concluded THCA and THCV, which certain each CB1 and CB2, could possibly scale back ache, irritation, and nervousness when both is used within the absence of different cannabinoids. This discovering is important since there’s a rising curiosity within the medical functions of single-cannabinoid preparations.
Given the plethora of firms which have reported the artificial manufacturing of particular person cannabinoids utilizing cell tradition strategies, pharmacological research like this one will play a key position in assessing how every cannabinoid behaves within the physique.
