Myrcene

Myrcene (β-myrcene) is a monoterpene hydrocarbon with the molecular formula C₁₀H₁₆. It is the most abundant terpene found in cannabis, comprising between 29% and 66% of the essential oil in many strains. Beyond cannabis, myrcene occurs widely in hops (giving beer its peppery, balsam aroma), mangoes, lemongrass, cardamom, and bay leaves.

Research suggests myrcene has sedative, muscle-relaxant, and anti-inflammatory properties. It is believed to enhance THC absorption across the blood-brain barrier, which may explain the folk wisdom that eating a mango before consuming cannabis intensifies the experience. In traditional Brazilian medicine, lemongrass tea rich in myrcene has long been used as a calming remedy.

Myrcene's dominance in a strain's terpene profile is often associated with the classic “indica couch-lock” sensation. Strains high in myrcene tend to produce deeply relaxing, sedating effects that are favored for evening use, pain management, and sleep support.
