An infusion of lemongrass (Cymbopogon), a citrusy grass; a caffeine free tisane, not true tea, see what counts as tea. Its traditional use is broad: lemongrass is a staple of South East Asian cuisine and a common soothing everyday drink across the region.

Bright, lemony, slightly grassy and clean; refreshing hot or iced, naturally low in bitterness. Cold brewed with a little mint it is one of the better summer tisanes in this cluster.

Some preliminary research on lemongrass compounds exists. It is a pleasant, culturally widespread drink rather than a proven remedy; the accurate description is "a nice, refreshing tisane", not a treatment. The wider herbal tea guide keeps that line throughout.

How to brew it

Boiling water, longer steep, no bitterness penalty; the grass releases slowly and forgives distraction. Great iced with a sprig of fresh mint, see iced tea.

Cautions

Generally well tolerated as a culinary herb and drink. The only flag is the cluster standard pregnancy and medication check before heavy regular use; check with a pharmacist or GP if relevant, see the disclaimer above.
