Essential oils are concentrated, hydrophobic liquids that contain aroma compounds from plants. They are sometimes called volatile or ethereal oils. The term essential does not relate to any necessary or important substances within the oil, only to the fact that the oil carries distinctive essence of the plant. The category essential oils does not have any unifying chemical properties, beyond conveying characteristic fragrances.
Essential oils are generally used in perfumes and cosmetics and for flavoring food and drink, and for scenting incense and cleaning products.
Interest in essential oils undergone a revival recently with the popularity of aromatherapy, a branch of alternative medicine that stressed the curative effects of aromatherapy. Some popular types of essential oil are sweet orange, mentha arvensis, peppermint, cedarwood, lemon and clove.
Essential Oils should not be applied directly onto the skin because of they can cause severe irritation of allergic reaction. They should instead be blended with a vegetable carrier oil before being applied. Common carrier oils include olive, hazlenut, almond and grapeseed.
