ABSTRACT
The scented Pelargonium hybrid cultivars used in the production of essential oil are large bush-like plants with small pink flowers and pointed scented leaves. They are widely cultivated in Madagascar, China, Algeria, Tunisia, Morocco, South Africa and India and various other countries. Essential oil of geranium is obtained by steam- or hydrodistillation of the leaves plus stems of Pelargonium cultivars, or from the herbaceous part. The essential oil is sparingly used in food and drinks, not only as flavor but also as a food preservative. It presumably has antibacterial, antifungal and insecticidal properties. Geranium oil is popular in aromatherapy, where it is used for menopausal problems, skin disorders, nervous tension and anxiety. Geranium oil is an amber to greenish yellow, clear mobile liquid which has an odor with floral rosy notes and green and minty accents. Contact allergy to/allergic contact dermatitis from geranium oil has been reported in over 30 publications.
