Ginger oil is a steam-distilled essential oil from the rhizomes of Zingiber officinale Roscoe. It consists primarily of sesquiterpene hydrocarbons including alpha-zingiberene (30-40%), beta-sesquiphellandrene, ar-curcumene, and beta-bisabolene, with smaller amounts of monoterpenes such as camphene and geranial. The oil exhibits a warm, pungent, spicy aroma and is widely used as a flavoring agent in foods and beverages. In traditional medicine it supports digestion and has demonstrated anti-inflammatory, antioxidant, and antimicrobial activities in scientific studies. Ginger oil is lipophilic and volatile, making it suitable for aromatherapy and topical applications when diluted.
