In a small saucepan, combine hot water, chopped lemongrass, lime juice, ginger and honey.
Give everything a stir and bring it up to a boil.
Reduce to low heat and let simmer for 5 minutes.
If adding green tea leaves, remove from heat, add in the tea, cover with a lid and let it steep for an additional 5 minutes.
Strain the lemongrass tea through a sieve and enjoy hot, or let it cool completely to enjoy iced.
Tip: Don't discard the lemongrass, lime and ginger just yet -- throw it into a large pot and fill with cold water. Bring it to a low simmer and it will infuse your home with an all-natural scent.
