Peppermint
The scent of peppermint oil has proved to be an effective treatment for nausea as research [4] conducted showed that it helped relieve symptoms in women who had undergone C-section better than a placebo. Asides from the soothing effects [5] of peppermint oil, the tea is another healthy form of relieving gastrointestinal discomfort.
It helps to relax the stomach muscles, allows food to break down quickly, and induces bowel movements, improving gut health and fighting constipation.
Lemon
Lemon is another food that helps treat nausea. It contains citric acid, which forms compounds that helps relieve [6] gastrointestinal discomfort that causes nausea. For example, constipation is when you experience reduced and difficult bowel movements, which causes stool to fill up the intestines, causing bloating and feelings of vomiting.
Limited bowel movements also cause an increase in gut bacteria, inducing nausea. Lemon has proved to be an effective remedy for pregnancy sickness; it can be mixed with honey for a less sour taste. Asides from ingesting lemon, a study showed that the scent of lemon oil helped reduce nauseousness in one hundred pregnant women better than antiemetics.
