There isn’t enough research on lemongrass tea to recommend a standard dosage for any condition. For dosing recommendations, consult a doctor or a qualified natural health practitioner.
To limit your risk of side effects, start with one cup daily. If you tolerate this well, you can drink more. Stop drinking the tea or cut back if you experience side effects.
If you don’t like drinking lemongrass, try cooking with it. Add a stalk or two to your favorite soup — it pairs well with chicken noodle. You can also add it to poultry or fish before baking. You can eat lemongrass raw, but mince it well since it tends to be stringy.
