What is Myrcene?

Myrcene is the most abundant terpene found in cannabis, typically comprising 20-65% of a strain's total terpene profile. This monoterpene is characterized by its earthy, musky aroma with subtle notes of cloves and herbal undertones. Myrcene serves as a key indicator of cannabis effects, with concentrations above 0.5% generally associated with sedating, indica-like properties. Beyond cannabis, myrcene occurs naturally in hops, lemongrass, thyme, and mangoes. In the cannabis plant, myrcene concentrations can range from trace amounts to over 2% by dry weight. Research suggests myrcene may enhance the permeability of cell membranes, potentially allowing other cannabinoids like THC to cross the blood-brain barrier more effectively—a phenomenon known as the "entourage effect." Commercially significant cannabis strains high in myrcene include OG Kush (often 0.5-1.5% myrcene), Granddaddy Purple (frequently 1-2%), and various Skunk varieties. Myrcene-dominant strains are often marketed for evening use due to their potential relaxing properties, though individual responses vary significantly. The terpene's boiling point is approximately 166-168°C (331-334°F), making it somewhat volatile during cannabis processing. This characteristic influences extraction methods and storage considerations for cannabis products. Many concentrate manufacturers specifically preserve myrcene through controlled temperature processes to maintain desired product profiles. Laboratory testing for myrcene is standard in regulated cannabis markets, with results typically expressed as percentages or milligrams per gram. States like California, Colorado, and Washington require comprehensive terpene testing, including myrcene quantification, for retail cannabis products. This data helps consumers make informed choices based on desired effects and flavor preferences. **Disclaimer:** This information is for educational purposes only and does not constitute medical advice.
