Beta-Caryophyllene
Beta-caryophyllene is the spicy, peppery terpene found in black pepper and cloves. It is unusual among terpenes because it can also interact with the body's CB2 receptors, which is why researchers are interested in it. It shows up in many dessert strains like GSC and Gelato.
What it smells like
Peppery, spicy, woody. You'll also find it in Black pepper, cloves, cinnamon.
Boiling point
About 266°F / 130°C. If you use a temperature-controlled vaporizer, terpenes vaporize at different points, which is one reason the same flower can taste different at different settings.
A note on terpenes and effects
Terpene research in cannabis is still young. Aromas are real; claims about specific effects are generalizations. The best guide is your own experience with a strain, starting low.
