For example, terpenes appear to play a part in influencing the effects of THC and CBD in the body. In a review of people with epilepsy, those who took full-spectrum CBD extract—including cannabinoids and terpenes—experienced improved symptoms and fewer side effects than those who took CBD isolate, only containing cannabinoids. Full-spectrum cannabis extract is whole-plant medicine, containing cannabinoids, terpenes, and other compounds that are present in the plant.
The researchers also found that full-spectrum CBD extract was four times more potent than the CBD isolate, meaning patients could take a significantly lower dose, and attributed this to the therapeutic synergy of cannabinoids and other compounds, such as terpenes.
More recent research has found that terpenes boost cannabinoid activity, but high concentrations of terpenes were needed to see this enhancement.
It’s vital to acknowledge that much is still unknown about terpenes and their interactions with other terpenes, cannabinoids, and flavonoids present in cannabis. In addition, the majority of the research we do have is based on animal or test-tube models.
Nonetheless, growing clinical interest in these aromatic compounds is yielding some fascinating findings. It’s likely that the coming years will see a more sophisticated understanding of terpenes develop, and how they behave both individually and synergistically.
