Key result
Garlic supplementation lowers blood pressure comparably to standard antihypertensive medications in mild-to-moderate hypertension.
Why the study?
Hypertension is a major modifiable cardiovascular risk factor with barriers to optimal pharmacological management, prompting interest in complementary approaches like garlic supplementation.
Does garlic supplementation reduce blood pressure in hypertensive patients?
Does garlic supplementation reduce blood pressure in hypertensive patients?
Garlic supplementation is a culturally acceptable, cost-effective complementary therapy that can modestly reduce blood pressure in hypertensive patients.
Hypertension represents a widespread global health concern and is a primary modifiable risk factor for cardiovascular diseases (CVDs), playing a significant role in global mortality rates. Although effective pharmacological treatments exist, various obstacles such as inadequate medication adherence, side effects, and limited access impede optimal blood pressure management, especially in low-resource environments. Approaches in complementary and integrative medicine (CIM), such as dietary phytotherapeutics, have garnered attention as supplementary strategies. Garlic (Allium sativum), in particular, has been thoroughly examined for its advantages to cardiovascular health. It contains bioactive sulfur compounds like allicin, diallyl disulfide, and S-allyl cysteine, which demonstrate vasodilatory, antioxidant, anti-inflammatory, lipid-lowering, and antithrombotic effects. These compounds enhance endothelial function, regulate nitric oxide bioavailability, inhibit angiotensin-converting enzyme (ACE), and positively affect lipid metabolism and inflammatory pathways. Clinical research, including randomized controlled trials and meta-analyses, validates garlic's effectiveness in lowering both systolic and diastolic blood pressure, with results comparable to standard antihypertensives in cases of mild to moderate hypertension. Additionally, garlic's availability, cost-effectiveness, and cultural acceptance make it a practical complementary intervention, particularly in resource-limited areas. This narrative review consolidates current findings regarding garlic’s pharmacodynamics, clinical effectiveness, safety, and its incorporation into hypertension treatment strategies. The review further emphasizes the vital role of nurses in evaluation, patient education, monitoring, and culturally sensitive care to safely introduce garlic supplementation into holistic hypertension management plans. Integrating garlic into comprehensive cardiovascular care may enhance blood pressure regulation and diminish CVD risk, aligning with global public health initiatives advocating for sustainable, food-based solutions.
