Topically, Ginger Essential Oil can be useful in blends and formulations intended to help improve circulation. It's a frequent addition to blends for massage, arthritis and muscle aches and pains.
When used topically at low dilutions or in a diffuser, Ginger Oil can help to ease nausea and motion sickness. Since Ginger Oil is so strong, I do not recommend that anyone without a formal education in herbalism or aromatherapy take it without being under the care of a qualified aromatherapy practitioner (instead, try Ginger Tea or Crystallized Ginger).
Aromatically, Ginger Essential Oil is spicy and warming. Though it is especially well suited for fall and winter months, I use it all year round. I love combining Ginger Oil in the diffuser with citrus oils and other spice oils.
