Ginger has a spicy, woody aroma and is a warming and stimulating oil. The oil is extracted by means of steam distillation from the dried, ground-up root (rhizome) of the plant. It is a good travel companion as it relieves nausea, making it great for morning and travel sickness, and it helps with digestive complaints. It can be used in a massage oil to soothe aching joints and muscles, good for arthritis and stimulating circulation, and as a warming ingredient in a chest rub for a cold or flu.
