Can CBD, herbal supplements affect the heart?

The patient even developed a feared and potentially deadly consequence of QT prolongation called Torsades de pointe, which can degenerate to sudden cardiac death,” he told MNT.Dr. Paz said that thanks to the clinical team the cause of these effects was identified, and the electrical abnormality resolved after the patient stopped taking them.This particular case study examined supplement use in one individual and the potentially severe cardiac problems that may follow. Pharmacology expert Professor Gary Stephens from the University of Reading, who was also not involved in the study, noted to MNT that more clinical trials regarding the use of these supplements were needed because of the limited data.We need to perform controlled clinical trials with properly defined medicines of standardized composition,” he said.However, Prof. “I’m unfamiliar with berberine, but the authors point out themselves that it has been reported to cause the cardiac side effect in the title of the paper,” he added.Dr. Stephen Alexander with the University of Nottingham, and a cannabis expert who was not involved in the study, said people should use supplements cautiously. “I would not expect the use of CBD or hemp oil to have a widespread negative impact on cardiovascular health, but it does underline the need to respect these agents and to treat them seriously (rather than to exceed recommended doses or combine with other poorly characterized supplements),” he told MNT.He said the study highlighted the need for greater awareness and education about the use of supplements, in particular those derived from cannabis.Disclaimer: Professor Gary Stephens has done some consultancy work for Jazz Pharmaceuticals.
