Lemongrass tea may help treat oral infections and cavities, thanks to its antimicrobial properties.
Two of the main compounds in lemongrass, citral and geranial, are thought to be responsible for its anti-inflammatory benefits.
The citral in lemongrass is also thought to have potent anticancer abilities against some cancer cell lines. This occurs either by causing cell death directly or boosting your immune system so that your body is better able to fight-off cancer on its own.
Lemongrass is a known diuretic. A diuretic makes you urinate more often, ridding your body of excess fluid and sodium. Diuretics are often prescribed if you have heart failure, liver failure, or edema.
