how much eucalyptus oil can you ingest?
Small doses of eucalyptus oil (0.05 to 0.2 milliliters a day) can be taken internally by adults. Always dilute the oil in warm water before consuming it. To prepare an infusion, boil one to two teaspoons of the chopped leaves in a cup of water and steep for 10 minutes. You can drink up to two cups a day.
