Supports Digestion: Known for soothing properties, the tea helps relieve bloating, cramps, and indigestion, and may protect the stomach lining.
Anti-inflammatory: Research suggests lemongrass's citral content can help reduce inflammation, a factor in chronic diseases.
May Lower Blood Pressure: Some studies indicate it can promote vasodilation, contributing to lower blood pressure.

What Makes Lemongrass Tea So Beneficial?

Lemongrass (Cymbopogon citratus) is a tropical plant known for its fresh, citrus aroma and taste. It has been used for centuries in cooking and traditional medicine in Asia because of its healing properties. The health benefits of drinking lemongrass tea come from its rich mix of citral, flavonoids, and phenolic compounds.

A Closer Look at Antioxidant Power

Antioxidants are important for protecting cells from free radicals that can cause chronic diseases. Lemongrass tea is a natural source of these protective compounds. A review from 2021 showed that lemongrass has antioxidants, such as chlorogenic acid, isoorientin, and swertiajaponin, that help fight oxidative stress. This cellular defense mechanism is vital for overall health and lowers the risk of health problems.

Soothing Digestive Wellness

One of the most well-known traditional uses for lemongrass tea is to support digestive health.

Relieves bloating and cramping: The tea is a remedy for settling upset stomachs, reducing bloating, and easing stomach cramps.
Combats ulcers: Animal studies suggest that lemongrass oil may help protect the stomach lining from damage caused by agents like aspirin and alcohol.
Addresses gastritis: Rich in anti-inflammatory flavonoids and tannins, lemongrass can help neutralize stomach acid, which benefits those with acid reflux and gastritis.

Anti-inflammatory and Antimicrobial Effects

Chronic inflammation is a major risk factor for many illnesses, including heart disease and diabetes. Research indicates that lemongrass has anti-inflammatory benefits that may help stop the release of inflammation-causing markers in the body. It also has antimicrobial capabilities.

Fights fungal infections: Lab studies show that lemongrass oil has antifungal effects against Candida albicans, a common cause of yeast infections.
Supports oral hygiene: Some studies indicate that lemongrass oil can be effective in reducing plaque and gingivitis.

Potential Benefits for Heart Health

Studies have looked at the potential role of lemongrass in supporting heart health. Its anti-hypertensive properties are thought to lower blood pressure by helping blood vessels relax and widen. Additionally, some research suggests it may help regulate cholesterol levels by preventing cholesterol absorption. These findings are promising, though more extensive human studies are needed.
