Myrcene: An Overview of a Common Terpene
Myrcene, or $\beta$-myrcene, is a naturally occurring monoterpene and a primary organic compound found in a wide variety of plants, contributing to their distinct flavor and aroma profiles. It is most notably associated with an earthy, musky, and herbal scent, sometimes with hints of tropical fruit and spice. Beyond its sensory contributions, myrcene is also studied for potential health benefits, including anti-inflammatory, analgesic (pain-relieving), and sedative effects.
This terpene plays a significant role in the entourage effect, a theory that posits that the synergistic interaction between cannabinoids and terpenes in plants like cannabis can create more pronounced and specific effects than any single compound alone. Its presence is therefore of great interest to both culinary enthusiasts and those in the natural wellness space.
The Fruit Champion of Myrcene: Mango
When the conversation turns to which fruit has the most myrcene, the clear winner among commonly consumed fruits is the mango. The sweet, musky, and earthy aroma of a ripe mango comes largely from its myrcene content. The concentration varies by variety and ripeness, with some reports suggesting levels of up to 6.5 mg per 100g of fruit in specific cases.
While mango is the top contender in the fruit category, it is important to note that its myrcene content pales in comparison to other natural sources. This fact challenges the widely circulated myth that eating a mango can significantly enhance a cannabis high. The amount of myrcene in a single mango is far too low to have a meaningful pharmacological effect, especially when compared to the concentrated levels found in many cannabis strains.
Beyond Fruit: Herbs, Hops, and Spices
While mangoes are the best fruit source, the highest concentrations of myrcene are found in other parts of the plant kingdom. The truly potent sources of this terpene are often herbs, spices, and hops.
Hops (Humulus lupulus)
Hops, the primary flavoring agent in beer, are exceptionally rich in myrcene. In some varieties, myrcene can constitute between 30% and 60% of the total hop oil content, and can even exceed 70% in some American varieties like Cascade and Centennial. This high concentration contributes significantly to the herbal, citrusy, and earthy notes of certain beer styles, particularly IPAs.
Thyme (Thymus vulgaris)
Thyme is another major source of myrcene. Wild thyme leaves have been shown to contain up to 40% myrcene by weight. This makes thyme a potent source of the terpene, and its essential oil is used in aromatherapy and for its traditional medicinal properties.
Lemongrass (Cymbopogon citratus)
Lemongrass, a staple in Southeast Asian cuisine, also contains myrcene, with some essential oils having concentrations as high as 8%. It is often used to make relaxing teas in folk medicine.
Other Sources
Other plants containing notable amounts of myrcene include:
- Bay Leaves: Contain smaller amounts of myrcene.
- Basil: Offers a fresh, spicy aroma partly from its myrcene content.
- Parsley: Also contains myrcene.
- Cardamom: Contributes to its warm and spicy flavor profile.
Comparing Myrcene Levels: Fruit vs. Herb
The following table illustrates the relative myrcene content in various plant sources, offering a clear comparison between the top fruit and other contenders.
| Source | Myrcene Concentration (approx.) | Notes |
|---|---|---|
| Hops (total oil) | 30-70% or more | Very high concentration; volatile during heating. |
| Wild Thyme (leaves) | Up to 40% by weight | One of the most concentrated non-cannabis sources. |
| Lemongrass (essential oil) | 7-11% | Popular for teas and cooking. |
| Mango (pulp) | 0.09-1.5% by weight or 6.5 mg per 100g | Highest fruit source, but highly variable. |
| Parsley | ~3.7 mg per 100g | A culinary herb with modest myrcene. |
As the table shows, while mango is the leader among fruits, its myrcene concentration is significantly lower than that found in herbs and hops. For someone seeking the highest possible natural intake of this terpene, focusing on herbs and spices would be far more effective than relying solely on fruit.
The Health Benefits and Effects of Myrcene
Beyond flavor, myrcene has been the subject of research for its therapeutic potential. Its most studied properties include:
- Anti-inflammatory: Studies, including one on human cartilage cells, have shown myrcene's anti-inflammatory effects, suggesting it could slow disease progression in conditions like osteoarthritis.
- Analgesic: Myrcene has demonstrated central and peripheral pain-relieving effects in animal models.
- Sedative: It has calming and sedative properties, with lemongrass tea (rich in myrcene) traditionally used as a sleep aid.
- Antioxidant: Research indicates myrcene may protect against UV-induced skin aging by acting as an antioxidant.
- Antimicrobial: A 2001 study showed that myrcene, along with other terpenes, possesses antimicrobial properties that can fight bacteria.
These potential benefits, while promising, often require higher concentrations than a single fruit can provide. Most research uses concentrated extracts or essential oils. For consumers, the effect of myrcene from foods is more subtle, contributing to the overall aromatic and flavor profile rather than providing potent therapeutic effects.
Conclusion: The True Myrcene Powerhouses
In conclusion, if you are looking for the fruit with the most myrcene, the answer is the mango. However, the mango is not the most concentrated source of myrcene in nature by a long shot. Herbs like wild thyme and spices like hops contain far higher levels of this earthy and musky terpene.
Understanding the myrcene content across different plants provides a more complete picture of this intriguing compound. Whether for culinary purposes or exploring its potential health benefits, knowing the true powerhouses of myrcene allows for a more informed approach. For those seeking the highest concentration, turning to herbs and hops is far more effective than relying on fruit alone.

A Comprehensive Comparison: Myrcene in Different Plant Sources
To further illustrate the disparity, consider that some hop varieties can have myrcene content that is orders of magnitude higher than that found in mangoes. While a ripe mango might have myrcene levels up to 6.5 mg/100g, some hops have myrcene making up over 50% of their essential oil, a comparison that highlights the true scale of concentration.
This information is valuable for a wide range of applications, from brewing craft beer to understanding traditional herbal remedies. The myrcene present in lemongrass tea, for instance, has long been associated with its calming effects in folk medicine, a property linked to its terpene content. Ultimately, while the mango holds the title among fruits, the crown for the overall most myrcene-rich food source belongs firmly to the herbal and spice categories.
Health Effects and Practical Use
The reported effects of myrcene, including its anti-inflammatory and sedative properties, are primarily observed in studies involving concentrated extracts or very high doses. The amount of myrcene consumed from eating a mango, for example, is minimal and unlikely to produce noticeable therapeutic effects on its own. The synergistic interaction with other compounds, particularly cannabinoids, is what makes its role so interesting in the context of cannabis. However, the idea that a single mango can drastically alter a cannabis high is more folklore than scientific fact due to the low bioavailability of myrcene from fruit compared to other sources.
Summary of Myrcene Sources
In summary, while mangoes are the leading fruit source of myrcene, the highest natural concentrations are found in herbs and hops. Thyme, in particular, stands out as an incredibly potent source. The health benefits associated with myrcene are typically linked to higher doses found in concentrated products rather than standard dietary intake from fruits. Consumers looking for the most myrcene from a food source should focus on herbs and hops, reserving the mango for its delicious flavor and modest terpene contribution.
What This Means for Consumers
For consumers, understanding the myrcene landscape is key. If you're seeking the calming or anti-inflammatory benefits associated with this terpene, you might find more success with myrcene-rich essential oils or specific herbal teas, rather than relying on fruit consumption alone. For those interested in the full spectrum of effects within cannabis, appreciating myrcene's contribution to the overall profile is important, but tempering expectations regarding the effect of a mango is wise.
Ultimately, the knowledge that certain herbs and hops contain far more myrcene than any fruit enriches our appreciation for the diverse chemical makeup of the plant world. The next time you enjoy a hoppy beer, a mango smoothie, or a dish seasoned with thyme, you'll have a more complete understanding of the musky, earthy terpene that makes each so unique.
