Myrcene is one of the more researched terpenes because of the synergistic properties that it brings to the plants that emit it. Learn more about terpenes every Terpene Thursday on the blog.

This issue we featured β-Myrcene, citing studies that show its abilities to help reduce inflammation while also increasing our brain’s ability to soak up more THC and reducing the resistance of the blood brain barrier. 

Molecular Mass: 136.23404 g/mol

Decarboxylation Point: 115-145°C (239°F to 293°F)

Boiling Point: 168 °C (334 °F)

Vapor Pressure: 7.00 mm Hg ( 20 °C)

LD50 (Lethal Dose): >5g/kg (Compared to Nicotine: for rats – 50 mg/kg,  for humans – 0.5-1 mg/kg)

Aside from being most stoner’s favorite terpene myrcene is also commonly used in the perfume industry but as an intermediary ingredient in preparing other flavors such as linalool, citronellal, and geraniol among others. There is a bush in Brazil that has been proven after the fact to have high amounts of β-myrcene was used as an ancient remedy for hypertension, diarrhea, dysentery, and diabetes which provides evidence that we’re not the first culture to appreciate the benefits of this terpene. Myrcene is found in a lot of common herbs, fruits, and flowers that we use daily including cannabis. Many strains that test higher in myrcene will have less psychoactive effects while experiencing more effects in the body. 

Myrcene is an olefinic natural organic hydrocarbon that can be found in:

  • Lemongrass
  • Mangoes
  • Cannabis
  • Sweet Basil
  • Bay Laurel
  • Ylang ylang
  • Wild thyme
  • Parsley
  • Hops

The phenol emits a scent that has been described as fruity, earthy and even clove-like. Cannabis strains that have tested high in terpenes in the past include White Widow, Skunk #1, Pure Kush, Himalayan Gold, and El Nino.  When smoked in the form of cannabis or inhaled through aromatherapy it has been found that myrcene influences an endogenous opioid system in the body which is why some people associate the phenol with ‘couch-lock’ effects in cannabis.
Of all of the terpenes that are known to exist in cannabis flowers myrcene is by far the most studied. In these studies, it was concluded that myrcene can have anti-anxiety effects and, in high doses, can cure those sleepless nights insomniacs are all too familiar with. Many people in cannabis culture know about myrcene because of how the terpene makes it more straightforward for cannabinoids and terpenes to reach receptors by making the blood brain barrier easier to penetrate. This fact is why myrcene gets the reputation for enhancing all of the effects of cannabis.  

Various studies have shown myrcene to be:

  • Analgesic
  • Anti-bacterial
  • Anti-diabetic
  • Anti-inflammatory
  • Antidepressant
  • Anti-insomnia
  • Anti-Proliferative/Anti-Mutagenic
  • Antipsychotic
  • Antispasmodic
