Peppermint oil is a good home remedy for nausea and headaches. To quickly alleviate the pain of a headache, simply apply it in a diluted form directly on the forehead. Inhaling peppermint oil can eliminate the effects of nausea and motion sickness, simply because of its relaxing and soothing effects. Its cooling and anti-inflammatory properties are part of the reason why it is so successful at relieving headache symptoms, and it is even used to reduce the pain of migraines in certain patients within 15 minutes of topical application, according to a study done in 2007.
