When it comes to fibromyalgia symptoms, those three are significant. A 2017 paper published in Expert Opinion on Therapeutic Targets suggested CBD as a possible way to diminish the activity of brain cells called glia, which leads to central sensitization. That’s a major feature of fibromyalgia and other central sensitivity syndromessuch as chronic fatigue syndrome, irritable bowel syndrome, and migraine.

Fibromyalgia also involves something called endocannabinoid deficiency. That’s the system that deals with your body’s natural endocannabinoids as well as cannabis products that you may take in. That makes cannabis products a promising treatment.A 2016 review published in Cannabis and Cannabinoid Research found evidence that CBD is effective in migraine and irritable bowel syndrome, which are related to fibromyalgia. It also stated that some cannabis-based treatments appeared effective for fibromyalgia. The authors stated that CBD is often preferable to patients due to the high and other effects associated with THC.

Several studies have suggested that CBD can fight inflammation. Fibromyalgia isn’t currently classified as an inflammatory condition, but research suggests that at least some cases may involve inflammation of a body-wide web of connective tissue called the fascia. If that’s accurate, it could be one more reason CBD should be considered.
