Eucalyptus globulus, Frankincense, pine, peppermint , rosemary, wintergreen, or lemon to name a few good ones. Use them to inhale and spread on the bottom of your feet by diluting with coconut oil or other vegetable oils. We use alot of essential oils but I do use an Essential Oils Desk Reference and for children it's best to dilute, supervise and keep away from eyes as essential oils are very powerful and can cause irritations. Using a steam inhaler made for the use of essential oils is the best method in my opinion.
