Beta-caryophyllene (BCP) is a natural terpene found in plants like black pepper, cloves, hops, and cannabis. It provides spicy, woody, and pepper-like aromas and is studied for its unique properties, including CB2 receptor interaction. In cannabis, BCP influences aroma profiles in strains like OG Kush and Girl Scout Cookies. Its quality depends on source, extraction, testing, and purity standards. Unlike CBD and THC, BCP is a terpene, not a cannabinoid.
