Clinical Trial: Oral CBD Dosing Reduces Pericarditis Pain and Recurrences
BY NORML POSTED ON JULY 30, 2026
Rochester, MN: The twice-daily administration of an oral formulation of purified CBD reduces pericarditis (chest) pain and recurring inflammation, according to Phase II clinical trial data published in the Journal of the American Heart Association.
Researchers at the Mayo Clinic in Minnesota and the Cleveland Clinic in Ohio assessed the safety and efficacy of orally administered CBD in 27 patients with recurrent pericarditis. Investigators assessed participants’ pain at baseline and following eight weeks of treatment. Some patients opted to continue using CBD for an additional 18 weeks.
Patients’ pericarditis pain scores fell 3.7 points on average (on a 10-point pain scale) following eight weeks of treatment. Over the full 26 weeks, patients’ pain scores fell 4.3 points on average. Seventy-one percent of patients who took CBD for the entire length of the trial remained free from pericarditis recurrence. Study participants were also able to reduce their use of prescription medications during the trial.
“In symptomatic patients with recurrent pericarditis, treatment with pharmaceutically manufactured cannabidiol resulted in reductions in pericarditis pain and systemic inflammation,” the study’s authors concluded. “The majority of patients remained free of recurrence during the extension period with weaning and discontinuation of background pericarditis medications. … Overall, these findings support larger, definitive randomized controlled trials evaluating the efficacy and safety of pharmaceutically manufactured cannabidiol in pericarditis.”
