Ginger is a perennial herb that can stand up to about 3 - 4 feet high and has a thick spreading tuberous rhizome. The root of ginger is distilled over high heat, for extracting the oil. This essential oil is widely demanded by aroma therapists for aromatherapy practices due to its warm nature. Ginger oil is also widely demanded for topical application over muscles and joints owing to its warming and energizing effect. It is considered as a must have oil to use in winters due to its distinct therapeutic properties.
