Important: general information only, not medical advice. Lemongrass is a tisane, which makes it neither true tea nor a treatment. Some tisanes come with real cautions, from liquorice raising blood pressure to herbs that clash with medicines or are not advised in pregnancy. Pregnant, medicated or managing a condition? Tell a pharmacist or GP before drinking lemongrass regularly.

What it is

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 cooking and a common, gentle everyday drink across the region.

How it tastes

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.

What the evidence shows

Some preliminary research on lemongrass compounds exists. It is a pleasant, culturally widespread drink rather than a proven treatment; the accurate description is "a nice, refreshing tisane". 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.
