Peppermint

Peppermint has been used in folk medicine and aromatherapy for centuries. As with many plants, the chemicals responsible for the health benefits are found in the oily component. Many studies have indicated that peppermint oil can help with pain management in those who suffer from irritable bowel syndrome, or IBS. It appears to act by relaxing the smooth muscles of the colon, relieving discomfort associated with bowel motions. It also aids in the reduction of abdominal bloating, a typical digestive ailment.

There has also been some research that demonstrates that using peppermint in aromatherapy can aid with nausea. Peppermint aromatherapy significantly reduced nausea in a trial of over 1,100 women in childbirth. It has also been found to alleviate nausea following surgery and C-section deliveries.
