Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Pomegranate (Punica granatum) has been studied for its potential effects on hypertension (high blood pressure). Several clinical and preclinical studies suggest that pomegranate juice and extracts may help reduce blood pressure, largely attributed to their rich content of polyphenols, particularly punicalagins and anthocyanins. These compounds possess potent antioxidant and anti-inflammatory properties, which are believed to improve endothelial function—the ability of blood vessels to relax and contract properly.

Randomized controlled trials (RCTs) have provided evidence supporting the antihypertensive effects of pomegranate. For example, a meta-analysis published in 2017 in Pharmacological Research concluded that pomegranate juice consumption was associated with significant reductions in both systolic and diastolic blood pressure. The presumed mechanisms include enhancement of nitric oxide bioavailability, inhibition of angiotensin-converting enzyme (ACE) activity, and reduction of oxidative stress in the vascular system.

However, while results are promising, the evidence is not yet robust enough to recommend pomegranate as a sole or primary therapy for hypertension. Many studies have small sample sizes, short durations, and varying dosages and formulations. Nonetheless, as an adjunct to conventional antihypertensive strategies, pomegranate juice may offer modest benefits without significant adverse effects. Thus, its use is justified by a moderate level of scientific evidence.
