beta-caryophyllene is bicyclic sesquiterpenoid found in the essential oils of Cannabis sativa, Clove and rosemary. The beta-caryophyllene is the first dietary cannabinoid approved by FDA. It selectively binds to the cannabinoid receptor type 1 (CB1) and (CB2). It is used in the treatment regimens of inflamation, pain, osteoporosis and atheroscelerosis [Gertsch08]. (E)-BCP is identified as a functional nonpsychoactive CB2 receptor ligand in foodstuff and as a macrocyclic antiinflammatory cannabinoid in Cannabis [Gertsch08]. As a component of clove oil extracted from syzigium, used in herbal medicine to treat pain, it is shown to posses aneasthetic activity [Ghelardini].
Since it is extensively used as a fragrance chemical in food and cosmetics, its allergen potential was evaluated and shown that it rapidly oxidizes upon exposure to air and the caryophyllene oxide can be a mild skin allergen [Skold06].
The enzyme that catalyzes the cyclization of FPP to form beta-caryophyllene has been characterized from a number of plant species included maize where it has been shown that this trait was lost and regained during cycles of domestication [Kollner08a].
