Terpene Field Guide
my’-seen · the most-common terpene in cannabis
Earthy, ripe, sedating. The reason a heavy chemovar feels heavy.
If a strain smells like a hot greenhouse, mango skin, ripe fruit on the verge of turning, or wet basil left in the sun, you are smelling myrcene. It is heavy. It is grounded. It is the terpene most likely to make you say "this smells like weed."
It is also abundant in mango, lemongrass, hops, thyme, and bay leaves. The hop note in a heavy IPA is mostly myrcene. So is the back-of-the-mouth weight in a really ripe mango. Once you can name it, you smell it everywhere.
Myrcene is the terpene most associated with the couch side of cannabis. Body-heavy, slow, hands-getting-tingly, eyelids-getting-curious. Users commonly report deeper relaxation, easier physical settling, and a softer transition into sleep. It pairs well with strong THC for that classic indica weight, and softens harsher strains when it is the dominant terpene.
It is not a guarantee. Strains with the same myrcene percentage can land differently depending on the rest of the entourage and the person inhaling. But if you reach for a flower at the end of the day and want it to do most of the work, myrcene-dominant is a defensible bet.
These are well-known myrcene-leading strains. Real batches vary, so always check the label or the Terpenology scan for the actual percentage. Treat this as the starting line, not the finish line.

Myrcene is the most abundant terpene in commercial cannabis. Strains with more than about 0.5% myrcene by mass are typically the ones described as sedating or "heavy."
In animal models, myrcene shows sedative and muscle-relaxant effects independent of cannabinoids. The behavior in animals lines up with the body-weight feeling people describe.
Some researchers propose myrcene increases the permeability of the blood-brain barrier, which could enhance the effects of THC and other cannabinoids. The mechanism is plausible but not yet proven in humans.
The "mango trick" — eating a mango before consuming cannabis to intensify the effect — is widely shared in stoner folklore. The idea is that mango myrcene boosts THC uptake. Probably overstated, but not crazy on its face.
