Essential oils are concentrated oils that are derived from plants. Several types of oils are produced from citrus species, including oranges, lemon, and grapefruit.
Orange essential oil is extracted from the rind of the sweet orange, Citrus sinensis. This is done by a method called cold pressing, which uses pressure to squeeze the oils from the rind. Sometimes, the leaves and flowers from the orange plant can be used as well.
Research has shown that some essential oils may have specific health benefits.
