What is myrcene in cannabis?

Wondering what gives your cannabis that earthy, musky, mango-like aroma, and why some strains glue you to the couch? The answer might be myrcene.

When you spark up a joint or open a jar of fresh buds, that rich, herbal scent drifting out is not just THC doing its thing, it is myrcene, one of the most abundant and influential terpenes in cannabis. This aromatic compound shapes both the flavor and the feel of your favorite strains, from the sweet fruitiness of mango to the deep relaxation offered by evening varieties.

In this guide, we will break down what myrcene is, explore how it affects your cannabis experience, and highlight which high-myrcene strains deliver those signature relaxing vibes. You will also learn how to preserve myrcene in your stash and how it compares to other terpenes like limonene and pinene. Whether you are a seasoned smoker, a wellness-focused user, or a curious cultivator, understanding the potential of the myrcene terpene can completely change the way you choose and enjoy cannabis.

What is myrcene?

Known as the “mother of all terpenes,” myrcene (or β-myrcene) is the most abundant terpene in cannabis, responsible for its earthy, musky, and fruity aroma. Its name comes from Myrcia sphaerocarpa, a Brazilian plant long used in traditional medicine.

Chemically, the myrcene structure is an acyclic monoterpene (C₁₀H₁₆) that contributes heavily to the plant’s characteristic scent. Beyond cannabis, it is also found in mangoes, lemongrass, hops, thyme, and cardamom, and is used in cosmetics and flavorings for its rich fragrance.

Among its isomers, beta-myrcene is the most common and bioactive form. In cannabis, it may interact with cannabinoids like THC through the entourage effect, enhancing feelings of relaxation. Learn more about terpenes in our guide to flavonoids, terpenes, and terpenoids.

What does myrcene do in cannabis?

Ever wondered why some cannabis strains leave you feeling blissfully heavy and glued to the couch? That deep relaxation is often linked to the effects of the myrcene terpene. Known for its soothing qualities, myrcene is believed to promote relaxation, making it a defining component of many body-heavy, stoning strains. These are the myrcene terpene effects most commonly associated with calming, full-body varieties.

Some research suggests that beta-myrcene may increase the permeability of the blood-brain barrier, allowing cannabinoids like THC to work more efficiently, which is a key part of what is known as the entourage effect. This synergy could explain why high-myrcene strains are popular among users seeking deep relaxation and unwinding.

Beyond its physical effects, myrcene also influences how cannabis smells and tastes. Its earthy, herbal, slightly fruity profile defines the myrcene terpene flavor found in many of today’s most relaxing strains.

What does myrcene smell and taste like?

If you have ever opened a jar of cannabis and caught a musky, earthy, and slightly tropical aroma, you have likely encountered myrcene. The myrcene terpene flavor is known for its rich, herbal depth. It is earthy and musky, with tropical mango undertones and subtle hints of cloves and damp soil.

When smoked or vaped, myrcene in cannabis produces a smooth, slightly sweet taste with spicy and fruity undertones, reminiscent of mango, balsamic herbs, and a hint of citrus. This complexity makes it both grounding and inviting, one reason strains high in myrcene often feel as soothing to the senses as they do to the body. Because myrcene is a volatile monoterpene, even slight exposure to heat, light, or air can dull its aroma, making proper storage key to preserving that signature scent and flavor.

How to preserve myrcene in cannabis

Like all terpenes, myrcene is delicate. It begins to evaporate at relatively low temperatures, which means improper storage can quickly strip your buds of their key traits. To preserve their effects and flavor:

• Store your cannabis in airtight, light-proof containers, ideally made of amber glass or UV-protected material.
• Keep it in a cool, dark, and dry place, with temperatures between 15–21°C and humidity levels around 55–62%.
• Avoid frequent opening of containers, since repeated air exposure accelerates terpene loss.
• Steer clear of plastic bags or transparent jars left in sunlight, since light, oxygen, and heat are the main enemies of terpene preservation.

By following these simple guidelines, you will maintain the earthy, mango-like essence of myrcene and keep your buds potent, flavorful, and aromatic for weeks to come. If you are looking for more tips on storing your cannabis, take a look at our dedicated article.

Myrcene vs other terpenes

While myrcene stands out for its earthy aroma and potentially soothing effects, it is only one piece of the cannabis terpene puzzle. Each terpene contributes something unique to the plant’s character and the overall experience it offers.

By contrast, limonene offers uplifting effects, with bright citrus aromas reminiscent of lemons and oranges. It is common in energizing strains that promote motivation and focus. Pinene, on the other hand, contributes pine-like freshness and may support mental clarity and alertness, serving as a balance to the more stoning qualities of myrcene.

Other notable terpenes such as linalool, which has a floral lavender scent, and caryophyllene, which has a peppery and spicy aroma, add further nuance. Each works in harmony with cannabinoids to shape a strain’s unique personality.

In short, choose myrcene-rich strains when you want relaxation. Choose limonene or pinene when you want to stay clear-headed and inspired. For a deeper dive into how different terpenes work together, visit our guide to terpenes and terpenoids.

Is myrcene safe? Potential benefits and considerations

Myrcene is generally regarded as safe in natural amounts, especially when consumed through cannabis, fruits, or herbs. It has long been used as a flavoring and fragrance compound in foods, perfumes, and cosmetics, thanks to its pleasant, earthy, herbal aroma.

Although synthetic beta-myrcene was removed from the FDA’s food additive list for regulatory reasons, naturally occurring myrcene, such as what is found in cannabis, is still considered non-toxic and well-tolerated. Studies suggest potential anti-inflammatory and sedative effects, although most evidence comes from preclinical and anecdotal research.

Possible side effects are minor and usually limited to drowsiness associated with high-myrcene strains. In short, myrcene in weed and food sources is safe for typical use, offering potentially relaxing benefits without significant health concerns.

Make myrcene a part of your life

Now that you know what myrcene is and how it shapes the cannabis experience, you can use that knowledge to make smarter and more satisfying strain choices. Whether you want relaxing evenings or simply richer aromas, myrcene-rich cannabis offers a sensory and therapeutic edge that is well worth exploring.
