Five Botanicals.
One Precision Formula.
One Precision Formula.
Each ingredient targets a specific aspect of cardiac rhythm regulation — from qi tonification to blood stasis resolution — working synergistically through atrial-selective sodium channel modulation.
Codonopsis
Dang Shen
Qi-tonifying adaptogen that strengthens cardiac contractility and supports energy metabolism in heart muscle cells.
Polygonatum
Huang Jing
Yin-nourishing herb that modulates autonomic tone and reduces oxidative stress in myocardial tissue.
Notoginseng
San Qi
Potent blood-activating agent that improves microcirculation and resolves cardiac blood stasis.
Amber
Hu Po
Calming mineral resin that settles the heart spirit, eases palpitation anxiety, and promotes restful sleep.
Nardostachys
Gan Song
Aromatic rhizome with documented antiarrhythmic properties that regulates qi flow in the cardiac meridian.

Important: This product is not intended to replace prescribed antiarrhythmic medication without cardiologist consultation. Always consult your electrophysiologist before making changes to your cardiac treatment plan.
Frequently Asked Questions
Wenxin Keli carries CFDA Pharmaceutical Approval in China, where it is one of the most prescribed cardiac herbal medicines. In Western markets it is available as a dietary supplement. Its efficacy is validated by a 1,200-patient RCT published in Chinese Medical Journal and mechanistic studies published in Heart Rhythm by Charles Antzelevitch — one of the world's foremost cardiac electrophysiologists.
Clinical research has shown that Wenxin Keli combined with Amiodarone produces superior outcomes compared to Amiodarone alone. However, because it has real antiarrhythmic activity, you must consult your cardiologist before combining it with any prescription antiarrhythmic to avoid additive effects.
In the 1,200-patient clinical trial, significant PVC reduction was measured at 4 weeks. Many users report noticing fewer palpitations within 2-3 weeks. The recommended course is 1 packet dissolved in warm water, 3 times daily for up to 6 weeks.
Research by Burashnikov and Antzelevitch published in Heart Rhythm demonstrated that Wenxin Keli selectively inhibits sodium-channel current in atrial tissue while having minimal effects on ventricular electrophysiology. It also regulates calcium handling, reduces reactive oxygen species, and improves gap junction protein (connexin-43) expression — all critical for preventing arrhythmias.
In the 1,200-patient placebo-controlled trial, only 3 mild adverse events were reported in the treatment group versus 4 in placebo — meaning the treatment group actually had fewer side effects than placebo. No significant changes in liver function, kidney function, or ECG parameters were observed. Multiple reviews confirm it is "less proarrhythmic" than conventional antiarrhythmics.
