Understanding Myrcene

Your Comprehensive Guide to Myrcene

At The Botany Bay, we want you to know more about the compounds that shape your experience with hemp, cannabis, and botanicals. Myrcene is one of the most common terpenes in cannabis and is also found in many herbs and fruits. Known for its earthy, musky, and slightly sweet aroma, myrcene is often associated with calming, relaxing effects and plays a key role in the entourage effect.

What Is Myrcene?

Myrcene is a monoterpene, a type of aromatic compound produced by many plants. In cannabis, it is often the most abundant terpene in indica-leaning strains, though it appears in sativas and hybrids too.

Outside of cannabis, myrcene is found in hops, lemongrass, mangoes, basil, and thyme. It contributes to the earthy, herbal scent in these plants and may influence their traditional uses.

Itโ€™s one of the most common terpenes in nature and is biosynthesized by plants as a defense mechanism โ€” deterring pests and protecting against pathogens.

How Myrcene Works in the Body

While more research is needed, myrcene is believed to interact with the endocannabinoid system indirectly by influencing how cannabinoids bind to receptors. Some research and user reports suggest that myrcene may:

  • Contribute to muscle relaxation and a sense of calm

  • Affect the permeability of the blood-brain barrier, potentially enhancing the effects of cannabinoids

  • Influence sedation at higher concentrations

In cannabis, high-myrcene strains are often described as having a โ€œcouch-lockโ€ effect, though this is anecdotal.

These reported effects are not FDA-approved and are based on early research and user reports.

Natural Sources of Myrcene

While myrcene is well known in cannabis and hemp, it is found in a wide range of plants, fruits, and herbs that people encounter every day. Some of the most notable sources include:

  • Mangoes โ€” give off a tropical sweetness with an earthy undertone from myrcene

  • Lemongrass โ€” a citrusy herb rich in myrcene, often used in teas and cooking

  • Hops โ€” the plant that gives beer its distinct aroma, also a high-myrcene source

  • Thyme and basil โ€” culinary herbs with earthy and slightly spicy aromas

  • Bay leaves โ€” used in soups and sauces, contain myrceneโ€™s herbal depth

  • Parsley โ€” a fresh herb with subtle earthy notes

  • Guava โ€” tropical fruit containing both fruity and herbal terpenes

The exact myrcene content varies based on growing conditions, plant variety, and freshness. For example, ripe mangoes often have more noticeable myrcene aroma than underripe ones, and freshly harvested herbs generally contain more than dried or processed versions.

If youโ€™ve ever enjoyed a hoppy craft beer or the aroma of fresh mango, youโ€™ve experienced myrcene outside of cannabis.

Reported Effects and Benefits of Myrcene

Users often associate myrcene with:

  • A calming or sedating effect in higher amounts

  • Earthy, herbal, and slightly sweet flavors

  • A role in enhancing cannabinoid effects through the entourage effect
