Myrcene (β-Myrcene)

Overview

Myrcene is one of the most abundant terpenes in cannabis, known for its earthy, spicy, and musky aroma with subtle clove-like undertones. It is also naturally present in hops, mango, basil, thyme, and bay leaves.

Myrcene plays a central role in shaping the overall aromatic and physiological profile of many cannabis cultivars.
