Lemon balm (Melissa officinalis), balm, common balm, or balm mint, is a perennial herbaceous plant in the mint family Lamiaceae and native to south-central Europe, the Mediterranean Basin, Iran, and Central Asia, but now naturalized in the Americas and elsewhere.
It is grown as an ornamental plant and for its oil (to use in perfumery). The tea of lemon balm, the essential oil, and the extract are used in traditional and alternative medicine, including aromatherapy.
