Beta-caryophyllene

A common terpene with selective CB2-receptor activity — bridging the terpene–cannabinoid distinction.
Beta-caryophyllene is a sesquiterpene found in cannabis, black pepper, cloves, and rosemary. It is unusual among terpenes in being a **selective CB2 receptor agonist** — meaning it engages directly with the endocannabinoid system rather than acting only through aromatic or modulatory mechanisms.
This CB2 selectivity makes caryophyllene a candidate for anti-inflammatory and immune-modulatory effects without the psychoactive effects associated with CB1 activation. Pre-clinical research has explored it in chronic-pain, gastrointestinal-inflammatory, and anxiety models.
In Section 21 prescribing, caryophyllene content is rarely an explicit prescribing target — it is a feature of the broader full-spectrum profile of certain extracts. Patients on isolate-only formulations (CBD or THC alone) miss any caryophyllene contribution; patients on full-spectrum oils receive variable caryophyllene depending on the source material.
