Peppermint has long been used to calm uneasy stomachs, and is easily used. One drop (it is strong!) in a cup of warm water, sweetened if you like, can be sipped before and during the voyage. For the fussy ones, a drop can be added to a small amount of honey and taken from a spoon for the same effect.

Ginger essential oil is also known for its calming of upset stomachs - a little inhaled from a tissue or diluted in a carrier and rubbed on the abdomen can bring relief. One can also add a drop of ginger to warm water and drink as a strong tea - this may be effective for some food-related stomach issues as well, particularly when combined with the abdomen massage method.

Peppermint can also be uplifting to the weary driver or passenger - a drop or two placed on tissues in the car or near your seat will release the aroma into your surroundings. Be careful with this oil however, as getting it on sensitive areas of the skin (directly under the nose, and certainly near the eyes) can cause irritation. Tissues with the oil on it should not touch these areas directly.
