The most abundant terpene in modern cannabis — earthy, musky, and deeply relaxing.
Myrcene is typically the most abundant terpene in commercial cannabis cultivars, often comprising 20–65% of the total terpene fraction. It is a monoterpene found throughout nature — in hops (Humulus lupulus), mangoes, lemongrass, thyme, and bay leaves. Its earthy, musky, clove-like aroma is the dominant scent note in many indica-dominant strains. Myrcene is widely believed to enhance THC's sedative effects by increasing blood-brain barrier permeability, though direct human evidence for this mechanism remains limited.
Most abundant terpene in cannabis; the only terpene with credible (though still preclinical) evidence for blood-brain barrier permeability enhancement.

Biosynthesis Pathway
Synthesized via the MEP (methylerythritol phosphate) pathway from geranyl pyrophosphate (GPP) by myrcene synthase in cannabis trichomes.
Key Facts
Mechanism: GABA-A potentiation and CNS depression reduce sleep latency and increase sleep duration in rodent models
Animal studies show dose-dependent sedation. No human RCTs for isolated myrcene. Anecdotal reports of sleep enhancement are common but uncontrolled.
Mechanism: Indirect opioid receptor activation and COX inhibition reduce pain signaling in animal models
Demonstrated analgesic effects in hot-plate and writhing tests in mice. No human clinical trials for isolated myrcene analgesia.
Mechanism: Inhibits prostaglandin E2 synthesis and reduces inflammatory cytokine production
Anti-inflammatory effects shown in carrageenan-induced paw edema models. Human data absent for isolated myrcene.
Mechanism: GABA-A potentiation produces anxiolytic effects similar to benzodiazepines in animal models
Elevated plus-maze studies in rodents show reduced anxiety behaviors. No controlled human studies.
Mechanism: Central muscle relaxant effects via GABA-A modulation and reduced spinal cord excitability
Muscle relaxant effects observed in animal models. Widely reported anecdotally but no human RCTs.
