Geranium oil is grown in many regions, including Europe and Asia. There are many varieties and strains of the pink flower with a fresh, floral fragrance. Each variety differs in scent, but is near-identical in terms of composition, benefits, and uses. Geranium oil is widely used as an ingredient in perfumes and cosmetics. The essential oil is also used in aromatherapy to treat a number of health conditions. In aromatherapy, essential oils are inhaled using a diffuser, or diluted with carrier oils and applied to the skin for soothing benefits.
