Myrcene is usually the most abundant terpene in cannabis, and it is the one most people are describing when they call a strain "earthy" or "dank." It is not a cannabis exclusive though. You have met myrcene in mango, in hops, and in lemongrass, whether you knew it or not.

Where you find it in nature

Mango, hops, lemongrass, thyme, and bay laurel. The hops connection is why myrcene is a familiar note to anyone who knows craft beer.

Aroma and flavor

Earthy, musky, herbal, with a faint sweet-fruit edge underneath. It is the grounding, mellow base note in a terpene profile rather than the loud top note.

What the research says

Myrcene has a longer research trail than most terpenes, going back decades, though again it is mostly animal work.

• One of the earliest single-molecule studies, Rao and colleagues in the Journal of Ethnopharmacology in 1990, reported that myrcene produced analgesic (pain-response-reducing) effects in standard mouse tests.
• A 2002 study by do Vale and colleagues in Phytomedicine found that myrcene and limonene, given at high doses, increased sleeping time in mice by roughly 2.6 times.
• More recently, a 2024 study by Wang and colleagues in Pharmaceuticals identified beta-myrcene as a sedative and hypnotic component of lavender essential oil in a mouse insomnia model, and tied the effect to serotonergic signaling.
• Traditionally, myrcene-rich hops have long been used in folk sleep preparations, which is part of why it has the reputation it does.

The caveats matter here too. These are animal studies, and the doses used in the lab are far higher than anything in a food product. The mechanisms are still being worked out. This is research about the compound myrcene, not about our chews.

Where myrcene shows up in MONDAYS

Myrcene tends to sit in the more grounded, Evening-leaning profiles. If earthy and mellow is what you want, look at Raspberry Relief (LA Confidential) and Pound Town (London Pound Cake).
