Lemon (Citrus limon) essential oil has a bright, fresh aroma and a wide variety of applications, making it a well-known essential oil powerhouse. Aura Cacia Lemon Essential Oil comes from the United States. Like other citruses, lemon is one of the few essential oils expressed from the peel of the fresh fruit. The expression method uses pressure to physically squeeze the oil from plant tissue which is practical for citrus because of the unique oil-bearing structure of the rind.  This item is not available for expedited shipping and must be shipped via ground service.
