Cymene is a terpene that is commonly found in both cumin and thyme. Medical marijuana patients in need of a pain-relieving strain should keep their eyes open for a strain high in cymene, due to its anti-inflammatory and analgesic properties. Researchers are always searching for new ways to eliminate pain without the negative side effects associated with pharmaceutical pain-killers, and a study published in 2012 found that cymene significantly increased the amount of time it took for mice to feel pain caused by heat and inflammation. Another study published in 2015 found similar results, theorizing that cymene is able to significantly reduce pain and inflammation by modulating the opioid system. These results, while similar to the study in 2012, go a step further by attempting to determine the cause of relief. While it is clear that cymene has powerful medicinal effects, more research is needed to determine its mechanisms of action as well as its potential in replacing pharmaceutical pain-relievers.
