Because lemongrass contains significant amounts of antioxidants, including flavonoids, polyphenols, and terpenoids, it is considered healthy for everyone to consume it daily. This means that in addition to providing you with health benefits that many other teas may not deliver, the herb also has some interesting properties when consumed on its own. For example, when used as an alternative sweetener, it has comparable calorie and carbohydrate content to sugar. However, it does not cause any harmful side effects like sugar can cause when consumed in large quantities.
