A Powerful Source of Antioxidants
Lemongrass contains several key antioxidant compounds, including chlorogenic acid, isoorientin, and swertiajaponin, which protect the body from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to chronic diseases like heart disease and cancer. By neutralizing these free radicals, the antioxidants in lemongrass play a crucial role in cellular protection.
Anti-Inflammatory and Antimicrobial Properties
Chronic inflammation is a root cause of many health problems, including arthritis, heart disease, and diabetes. Lemongrass contains powerful anti-inflammatory compounds, most notably citral, which help to suppress the release of inflammation-causing markers in the body. This makes it a potential natural remedy for soothing inflammatory conditions. Furthermore, studies have shown that both lemongrass oil and extracts possess strong antimicrobial properties, demonstrating effectiveness against various bacteria, fungi, and even some viruses. This has led to its use in traditional medicine to fight infections and promote healing.
Supporting Digestive Health
Lemongrass has long been used as a folk remedy for upset stomach, indigestion, and other digestive issues. Animal studies suggest that lemongrass oil can help protect the stomach lining from damage, particularly from common medications like aspirin and from alcohol. A warm cup of lemongrass tea can help calm an upset stomach and ease bloating. The diuretic properties of lemongrass can also help flush toxins from the body and support healthy kidney function.
Promoting Oral Hygiene
In many cultures where lemongrass grows natively, chewing on its stalks has been a traditional practice for improving dental health. This has been backed by modern research, with studies indicating that lemongrass essential oil can be effective in combating the bacteria responsible for tooth decay, including Streptococcus mutans. Research has also shown that mouthwashes containing lemongrass oil significantly reduce plaque and improve gum health, sometimes more effectively than conventional alternatives. This makes it a compelling natural option for maintaining oral hygiene.

Potential Role in Managing Blood Pressure and Cholesterol
Research into lemongrass suggests a potential benefit for cardiovascular health. Several studies have pointed towards the herb's anti-hypertensive properties, with some human trials showing a moderate reduction in systolic blood pressure among those who drank lemongrass tea. Furthermore, a 2022 review highlighted that lemongrass extracts may help inhibit cholesterol absorption, though more human studies are needed to confirm these findings.
Further Benefits and Considerations
- Relief from Menstrual Cramps: Lemongrass tea is used in folk medicine to help soothe menstrual cramps and alleviate bloating, offering potential relief during menstruation.
- Potential Anticancer Properties: The compound citral, found in lemongrass, has shown promising anticancer properties against certain cancer cell lines in test-tube studies. However, this research is in its early stages and should not be considered a substitute for professional medical treatment.
- Diuretic Effects: As a natural diuretic, lemongrass can increase urination, which helps rid the body of excess fluid and sodium.
Conclusion: A Versatile and Beneficial Herb
Lemongrass is a versatile and valuable herb with a wide array of potential health benefits, supported by both traditional use and emerging scientific research. From its potent antioxidant and anti-inflammatory effects to its positive impact on digestive and oral health, this plant offers a natural way to support overall wellness. While many studies have focused on lemongrass essential oil and more research is needed to fully understand the effects of consuming lemongrass tea or using the herb in cooking, the evidence suggests it is a beneficial addition to a healthy diet. As with any herbal remedy, it is always best to consult with a healthcare professional before using lemongrass to treat a specific medical condition.
