Millions live with smoldering, low-grade inflammation that erodes arteries, joints, and organs over decades without obvious symptoms until a diagnosis arrives—often too late for simple reversal. A major 2025 analysis in Pharmacological Research – Natural Products examined citral from lemongrass (Cymbopogon citratus) and found it interrupts cellular signals that perpetuate this chronic state, offering a direct challenge to the pharmaceutical reliance on anti-inflammatory drugs that rarely address upstream causes.
Chronic inflammation as a silent accelerator
The review distinguishes acute inflammation—a short, protective response to injury—from chronic inflammation, a persistent, systemic process that damages tissues quietly for years. Citral modulates pathways including NF-κB and COX-2 suppression while reducing pro-inflammatory cytokines, according to the authors. This upstream action aligns with natural health principles that prioritize root-cause correction over temporary symptom relief.
Blood pressure improvements in human trials
Human studies provide concrete evidence of cardiovascular impact. In one trial with 72 male volunteers, daily lemongrass tea consumption produced a moderate reduction in systolic blood pressure and a lower heart rate compared with controls. Participants showed improved vascular function without reported adverse effects. A broader 2022 review of multiple human and animal studies reinforced these outcomes, attributing the effects to citral's ability to promote vasodilation, enhance blood flow, and support sodium/fluid balance. With nearly half of U.S. adults facing hypertension, these findings highlight an accessible, side-effect-sparing option that contrasts sharply with conventional medications.
Traditional use meets modern validation
Lemongrass has been steeped as tea in South and Southeast Asian traditions for centuries, valued for digestive, calming, and wellness support. Phytochemical studies confirm the whole plant delivers antioxidants alongside citral, contributing to antimicrobial and anti-inflammatory activity. Fresh stalks are now common in grocery stores; simply bruising and steeping them in hot water releases the active compounds.
Complementary natural strategies
Natural health practitioners frequently combine lemongrass with other anti-inflammatory plants such as turmeric and ginger, whose compounds target overlapping pathways for broader systemic support. This whole-food approach counters the inflammatory burden from processed diets and environmental exposures, empowering individuals to reduce reliance on synthetic interventions.
The 2025 review strengthens the case for citral as a modulator of chronic inflammation, with existing human data on blood pressure offering practical, immediate relevance. As chronic illness rates climb, lemongrass stands out as a low-cost, time-tested plant that delivers measurable physiological shifts without prescription dependency.
