The administration of plant-derived CBD is associated with improvements in patients suffering from insomnia, according to a review of human trials published in the journal Cannabis and Cannabinoid Research.
Investigators affiliated with Luther College in Iowa and with the Mayo Clinic in Rochester, Minnesota reviewed data from 34 human trials assessing the use of CBD on insomnia symptoms.
“All studies reported improvement in the insomnia symptoms of at least a portion of their participants,” the investigators reported. They concluded, “The results of our systematic review suggest that CBD alone or with equal quantities of THC may be beneficial in alleviating the symptoms of insomnia.”
Randomized, placebo-controlled trial data published in December reported that the short-term use of plant-derived cannabis extracts is well-tolerated and effective in patients diagnosed with insomnia, NORML noted. Patients in the study were administered either extracts containing 10mg of THC and 15mg of CBD or placebo for two weeks. Those receiving cannabis extracts experienced improved sleep quality by up to 80 percent and “60 percent of participants no longer classified as clinical insomniacs at the end of the two-week intervention period.”
