As it relates to cannabis, these are the large class of organic hydrocarbons present in the cannabis plant and responsible for the fragrant aromas which also maintain therapeutic benefits. According to MedicalJane, “terpenes are synthesized in cannabis in secretory cells inside glandular trichomes, and production is increased with light exposure”. Terpenes are found in higher concentration in cannabis plants that have yet to be dried and cured (fresh flower). Steam distillation and vaporization allow for extraction of these essential oils from the plant to be later integrated into extracted concentrates.
