Anti-arrhythmic agents work by modulating the electrical activity of the heart, improving circulation, and supporting the cardiovascular system to prevent or manage irregular rhythms. Herbs with anti-arrhythmic properties often have calming, circulatory, or adaptogenic actions. Hawthorn (Crataegus spp.) is widely used to support heart function and regulate heart rhythms by enhancing blood flow and strengthening the heart muscle. Motherwort (Leonurus cardiaca), known for its calming effects, is traditionally used to ease palpitations and mild arrhythmias associated with stress or anxiety. Linden (Tilia spp.) can also support cardiovascular health by relaxing tension in the heart and blood vessels. These herbs offer gentle, natural support for maintaining a steady and healthy heartbeat.
