A spicy, peppery terpene unique for its ability to bind directly to CB2 receptors, offering potential anti-inflammatory effects.
Beta-caryophyllene is a spicy, peppery terpene found in cannabis, black pepper, cloves, cinnamon, and oregano. What makes caryophyllene unique among terpenes is its ability to directly bind to CB2 receptors in the endocannabinoid system, making it the only known terpene that functions as a dietary cannabinoid.
Because caryophyllene activates CB2 receptors, it can produce anti-inflammatory and analgesic effects without any psychoactive component. A 2014 study in the European Journal of Pain found that topical application of beta-caryophyllene reduced inflammatory pain in animal models. Its CB2 activity also gives it potential for conditions involving immune dysregulation. This dual identity as both a terpene and a functional cannabinoid makes it one of the most pharmacologically interesting compounds in cannabis.
Strains with prominent caryophyllene profiles include GSC (Girl Scout Cookies), Original Glue (GG4), Bubba Kush, Chemdawg, and Cookies and Cream. If you bite into a black peppercorn and your cannabis smells similar, it is likely rich in caryophyllene. Interestingly, sniffing or chewing black pepper is a folk remedy for THC-induced anxiety, possibly because caryophyllene's CB2 activation helps counterbalance an overstimulated CB1 response.
