Woman, 56, struck by dangerous arrhythmia after taking CBD for 4 month

Herbal supplements like hemp oil that contain CBD (cannabidiol) are celebrated for their benefits. Researchers have found that CBD can help with stress relief and several other ailments. But doctors who recently treated a woman, 56, for heart problems after taking CBD for four months warned, ‘the potential negative side effects are often not foreseeable’.The researchers, who wrote about their patient in the journal HeartRhythm Case Reports, explained that the ‘exact composition’ of the supplements often varies widely.They also suggested there is still a lot to be learned about the properties of these supplements.The woman they treated went to the hospital after passing out but had suffered from dizziness for a month before admission. It turned out the dizziness was down to a change in her heart rhythm.She had developed a potentially life-threatening heart rhythm change known as Torsades de pointes.READ MORE: Dyschezia could signal spreading tumour of bowel cancer – sign that strikes on loo A woman who took CBD three to four times a day developed an abnormal heart beat (Image: GETTY)Dizziness, palpitations, fainting, and being short of breath are all common symptoms of changes in your heart’s rhythm, according to the Cleveland Clinic.The woman had been taking two types of hemp oil three to four times daily for four months.
