10 Herbs to Support the Heart
Cardiac health is vital to overall wellness, and incorporating herbal allies into a heart-healthy lifestyle may provide significant support. Below, we’ll explore 10 powerful herbs that have been traditionally and scientifically shown to support cardiac function. Always consult a healthcare provider before introducing potent herbs, especially when managing complex heart conditions.
1. Adonis vernalis (Adonis)
Adonis, a lesser-known herb, has cardiotonic properties due to its cardioactive steroid glycosides, such as adonitoxin. It improves the heart’s pumping efficiency (positive inotropic effect) and is especially useful in mild cardiac insufficiency and arrhythmias.
Indications: Cardiac insufficiency (NYHA stages I & II), arrhythmias
Dosage: Up to 3.0g/day of standardized Adonis powder
Caution: Do not combine with digitalis, as the effects may be additive.
2. Allium sativum/cepa (Garlic & Onion)
Garlic and onion have a long history of cardiovascular support. Animal studies show their potential to reduce arrhythmias caused by ischemia, possibly by enhancing circulation and reducing oxidative stress.
Indications: Ischemic arrhythmias, general cardiovascular support
Benefits: May reduce ventricular tachycardia and fibrillation during cardiac stress
3. Ammi visnaga (Bishop's Weed)
This herb supports coronary and myocardial circulation while offering mild inotropic and antispasmodic effects. It is particularly beneficial in angina and mild cardiac insufficiency.
Indications: Angina pectoris, tachyarrhythmias, cardiac insufficiency
Caution: May cause reversible cholestatic jaundice or phototoxicity in sensitive individuals.
4. Crataegus oxyacantha (Hawthorn)
Hawthorn is a star in herbal cardiology, improving coronary blood flow, reducing peripheral resistance, and supporting mild heart failure. Its vasodilatory and positive inotropic properties make it a cornerstone for long-term cardiac care.
Indications: NYHA stage II, mild bradyarrhythmias, hypertension
Dosage: 160–900 mg of standardized extract/day for at least 6 weeks
Key Point: Acts gently but effectively over time.
5. Leonurus cardiaca (Motherwort)
Motherwort is a soothing cardiac tonic. Its mild sedative and hypotonic effects make it suitable for arrhythmias associated with stress or anxiety.
Indications: NYHA stages I & II, arrhythmias, stress-induced palpitations
Dosage: Acute use: 5 drops of liquid extract every 30-60 minutes; chronic use: 5 drops 1-3 times daily
Note: Also supports nervous system balance.
6. Berberine (Hydrastis canadensis, Berberis species)
Berberine alkaloids are highly effective in reducing arrhythmias caused by ischemia and may lower the frequency of premature ventricular contractions (PVCs).
Indications: Tachyarrhythmias, ischemic heart conditions
Evidence: Studies suggest a 50–90% reduction in PVCs for most patients.
7. Convallaria majalis (Lily of the Valley)
Lily of the Valley is a potent cardiac tonic, helping to reduce elevated left ventricular diastolic pressure and improve venous hypertension. Its inotropic effects make it suitable for mild heart failure and arrhythmias.
Indications: Arrhythmia, cor pulmonale, NYHA stages I & II
Dosage: 0.6g/day of tincture or liquid extract
Caution: Monitor closely for toxicity, particularly with co-administration of medications like calcium salts or glucocorticoids.
8. Digitalis purpurea (Foxglove)
A potent and historically significant herb, Digitalis provides strong inotropic effects while slowing the heart rate (negative chronotropy). However, its narrow therapeutic window requires extreme caution.
Indications: Atrial fibrillation, atrial flutter
Dosage: Maintenance dose of 0.25mg/day (as digoxin equivalent)
Caution: Monitor ECG and serum levels to avoid life-threatening toxicity.
9. Rauwolfia serpentina (Rauwolfia)
This herb, from which the drug reserpine is derived, provides significant antihypertensive and sedative effects. It may also help reduce sinus tachycardia and anxiety-related cardiac issues.
Indications: Hypertension, sinus tachycardia, anxiety
Dosage: Equivalent to 0.25–0.5mg reserpine BID
Caution: Overdose may lead to confusion and depression.
The Importance of Safety and Supervision
Many of these herbs have powerful effects on the cardiovascular system and may interact with conventional medications or other herbs. Proper dosage and monitoring are critical to ensure safety and efficacy. Collaborating with a healthcare provider who understands herbal medicine is essential for tailoring treatment to individual needs.
By integrating these herbal allies into a heart-centered care plan, we can honor nature’s gifts in supporting cardiovascular health and holistic well-being.
