Myrcene is oftentimes the most abundant terpene in cannabis and it is the reason why some strains smell of cloves and hops. Myrcene has been meticulously studied and the results show that this terpene causes both sedative and analgesic effects with the potential to minimize inflammation. As early as 1990, researchers discovered that myrcene possesses the unique ability to stimulate the release of endogenous opioids, which explains how it is able to reduce nociceptive pain. In the same year, a separate group of researchers also concluded that myrcene offered powerful pain-relieving properties, suggesting that it should be offered as an alternate form of pain medication to the traditionally prescribed aspirin-like pharmaceutical alternatives. Cannabis patients who are looking for a strain that will improve the quality of their sleep should seek a strain that is high in myrcene. A 2002 study showed that myrcene promoted muscle relaxation and increased the sleeping time of mice compared to the control counterparts. Most would assume that the sedative effects produced by myrcene would also work as an anti-depressant and stress reducer, but research has proven this to be false. Interestingly, according to a study published in the Journal of Phytomedicine, high amounts of myrcene can increase anxiety instead of reducing it - something medical cannabis patients want to actively avoid.
