Lemongrass tea is made from the dried leaves or stalks of the lemongrass plant known by the botanical name Cymbopogom. The lemongrass plant grows in warmer temperatures and is native to South Asia. Today, the plant is frequently cultivated for use in tea and essential oils in Southeast Asia including Indonesia and the Philippines.

The lemongrass plant is also commonly known as tanglad, barbed wire grass, citronella grass, and silky heads. The plant has many different species including citronella grass, but the species used for tea is largely Cymbopogon citratus. The tea is naturally caffeine-free and can be enjoyed all day without adverse side effects for sleep. Thanks to its acidity, the tea leaves can be added in place of lemon juice to Butterfly Pea Flower Tea to turn the tea from a rich blue to a vibrant purple. It\\\\\\\\\\\\\\\'s also commonly added as a flavoring to black tea.
