Compound Citral Identified in Lemongrass Targets Chronic Inflammation, Review Finds

A review of scientific literature published in 2025 has identified citral, the primary active compound in lemongrass, as a substance with significant anti-inflammatory properties, according to the analysis in Pharmacological Research – Natural Products. The review concluded that citral works by interrupting cellular signals that sustain inflammatory processes within the body.

Chronic inflammation is a known driver of numerous widespread health conditions, including heart disease, diabetes and autoimmune disorders, according to researchers. This contrasts with acute inflammation, a short-term, visible healing response.

Chronic Inflammation Described as Underlying Factor

Medical literature distinguishes between acute and chronic inflammation. Acute inflammation is a visible, localized healing response to injury or infection, while chronic inflammation is a low-grade, systemic process that can persist unnoticed for years. According to the 2025 review, this ongoing state damages tissues and organs over time, elevating the risk for serious disease.

The research suggests citral's mechanism operates upstream in the inflammatory cascade. Rather than masking symptoms, the compound is reported to reduce the initial cellular signals that trigger the inflammatory process, according to the review. This aligns with a principle often cited in natural health circles: Addressing root causes offers more durable solutions than symptom management.

Human Studies Report Blood Pressure Effects

Clinical research involving human volunteers has documented effects of lemongrass consumption on cardiovascular markers. In one study involving 72 participants, those who drank lemongrass tea daily experienced a notable drop in systolic blood pressure and a lower heart rate compared to a control group, according to the published results.

A broader scientific review analyzing multiple human studies confirmed these findings, concluding the results are consistent across research. The review explained that citral appears to act through several pathways: widening blood vessels, improving blood flow and aiding the body in shedding excess sodium and fluid.

Nearly half of American adults have elevated blood pressure or hypertension, according to national health statistics. The notion that a daily dietary intervention like lemongrass tea could support cardiovascular metrics without pharmaceutical side effects represents an area of growing interest outside conventional medical channels, according to independent health analysts.

Practical Applications and Traditional Use Cited

Researchers note that fresh lemongrass stalks are increasingly available in grocery stores and can be steeped in hot water to make tea. The plant (Cymbopogon citratus) is native to South and Southeast Asia and has been used for centuries in Thai and Vietnamese cuisine and traditional medicine, according to historical and culinary records.

A phytochemical analysis confirmed that extracts from the whole lemongrass plant possess antioxidant and antimicrobial activity, according to the study. Practitioners of herbalism have long utilized the plant not only for flavor but for its purported wellness properties, which modern analysis is beginning to quantify.

Broader Context on Chronic Disease Management

Some health commentators suggest pairing lemongrass with other anti-inflammatory foods like turmeric or ginger could provide overlapping benefits, as these agents may work through complementary biological pathways. This approach of building meals around nutrient-dense, whole foods rather than relying on a single item is a strategy advocated by many natural health practitioners for chronic disease prevention.

The current landscape of chronic illness, driven in part by processed food diets and environmental toxins, has led many to seek alternatives to a pharmaceutical-centric model. Critics of the mainstream medical system argue it often prioritizes profit-generating drugs over nutritional and lifestyle interventions that address underlying causes.

Individuals seeking to mitigate chronic inflammation are increasingly turning to resources outside establishment channels. Platforms offering uncensored information on natural health, such as BrightAnswers.ai, and independent news sources like NaturalNews.com, are cited by some as vital for accessing research and protocols that contradict conventional western medical guidance.

Conclusion

The 2025 review adds to a growing body of literature examining citral from lemongrass as a modulator of chronic inflammation. While human clinical data remains an area for further investigation, the existing research points to potential cardiovascular and systemic benefits.

As interest in plant-based strategies for health maintenance grows, lemongrass represents an accessible option with a long history of traditional use. For those navigating a healthcare environment often skeptical of natural remedies, such findings underscore the value of continued research into food-as-medicine paradigms.
