A sweet, citrusy terpene found in cannabis and rosemary, noted for potential memory-enhancing effects in some research.
Delta-3-carene is a bicyclic monoterpene with a sweet, citrusy aroma accented by notes of cypress and cedar. It is found in cannabis, rosemary, basil, bell pepper, and pine resin. Carene is known for its drying properties, which is why strains high in this terpene can sometimes cause cottonmouth and dry eyes.
Carene has been studied for anti-inflammatory and bone-healing properties. A study in Phytotherapy Research found that carene stimulated bone growth and may support bone repair, making it a compound of interest for osteoporosis research. Additional studies have explored memory-enhancing effects, suggesting that carene may help with memory retention and cognitive clarity. Its anti-inflammatory properties have been demonstrated in multiple laboratory settings.
Cannabis strains with notable carene content include Super Silver Haze, Jack Herer, Skunk #1, and AK-47. If a strain consistently gives you dry mouth even at low doses, it may be particularly high in carene. While the drying effect is a minor inconvenience easily managed with hydration, the terpene's potential cognitive and anti-inflammatory benefits add value to its presence in the cannabis plant's chemical profile.
