Herbal Treatments for High Blood Pressure: Key Herbal Remedies
Garlic, Celery, and Other Common Herbal Medicines for Hypertension
Several herbal remedies have shown potential in lowering high blood pressure. Garlic (Allium sativum), celery (Apium graveolens), and hibiscus (Hibiscus sabdariffa) are among the most studied herbs. Research consistently finds that these herbs can significantly reduce both systolic and diastolic blood pressure in people with hypertension or prehypertension. For example, garlic can lower systolic/diastolic blood pressure by about 18/9 mmHg, celery by 38/15 mmHg, and hibiscus by up to 61/66 mmHg. Other herbs with evidence of benefit include black cumin (Nigella sativa) and ginseng (Panax ginseng) Lachovicz2025Sari2024Sari2024+3 MORE.
Additional Herbal Options: Green Tea, Rosella, Gotu Kola, and More
Other herbal treatments that have been reported to help manage high blood pressure include green tea, rosella flower, gotu kola, turmeric, cucumber juice, bay leaf, papaya juice, starfruit, African leaves, suruhan herbs, ginger, and cat’s whiskers. These plants are often used in traditional medicine and are believed to work through various mechanisms such as vasodilation, anti-inflammatory, and antioxidant effects Sari2024Sari2024Febyanesti2024+2 MORE.
Mechanisms of Action: How Herbal Remedies Lower Blood Pressure
Herbal medicines may lower blood pressure by several mechanisms. These include:
- Acting as vasodilators to widen blood vessels
- Providing antioxidant effects to reduce oxidative stress
- Blocking calcium channels
- Strengthening the endothelium (the inner lining of blood vessels)
- Inhibiting angiotensin-converting enzyme (ACE)
- Increasing nitric oxide production
- Reducing biogenic amines that can raise blood pressure Sari2024Febyanesti2024Siregar2023+2 MORE.
Herbal Supplements and Extracts: Evidence from Meta-Analyses
Meta-analyses and systematic reviews show that herbal supplements rich in phenolic compounds, such as resveratrol, cherry juice, beetroot juice, bergamot extracts, barberry, and pycnogenol, can also help reduce blood pressure. These supplements have a measurable effect on both systolic and diastolic blood pressure, but it is important to use the correct dosage to avoid possible digestive side effects Lipert2022Lachovicz2025.
Safety, Accessibility, and Traditional Use
Herbal treatments are often preferred in many communities because they are easy to obtain, cost-effective, and generally have fewer side effects compared to conventional medications. Many people use these remedies as part of their primary health care, especially in developing countries Siregar2023Wahyuni2023Febyanesti2024.
Conclusion
Herbal treatments such as garlic, celery, hibiscus, green tea, and several other plant-based remedies have demonstrated potential in lowering high blood pressure. These herbs work through multiple mechanisms and are widely used due to their accessibility and safety profile. However, while the evidence is promising, more high-quality clinical studies are needed to confirm their effectiveness and determine the best dosages for safe use. Herbal remedies can be considered as part of a comprehensive approach to managing hypertension, especially when combined with lifestyle changes.
