Terpenes are found in essential oils and hold numerous medical benefits. Terpenes (and terpenoids) are aromatic organic compounds found in many plants and even some insects. Plants developed terpenes to ward off herbivores that might eat them and to attract helpful predators and pollinators. Cannabis has naturally high levels of terpenes. Pungent cannabis flowers get their strong odours from being rich in terpenes.
With the help of ongoing research of the many benefits of essential oils, we are now beginning to understand the many benefits of strain specific terpenes and their synergy with CBD and THC.
