I started an Olive Leaf extract once a day 500mg and after 6 weeks of taking it once a day my PVCs went down from 20 per minute resting to 0 resting and rare during exercise at cardio re-hab when working out. I can't take beta blockers due to allergies so this came up in a comment by a gentleman using this support group. Toniiq LLC is the distributor. Absolutely, no side effects. I am sold on it.
