One of the most important spices in China and India, ginger provides a digestive stimulant in the cuisine of both nations. Ginger essential oil has a different aroma to the pungency of fresh ginger root—the oil is softer and sweeter with a very pleasant, spicy fragrance.
The anti-inflammatory and antibacterial qualities of ginger essential oil are due to a high concentration of sesquiterpenes. The oil may increase photosensitivity, however, so keep this in mind when using topically. As with other essential oils, dilute ginger essential oil to avoid the risk of irritation.
